“For a long time now, a large number of [escaped slaves] have established themselves on lofty Maroon Hill in the mountains toward the west end of the island [of St. Croix]. … They are there protected by the impenetrable bush and by their own wariness.”

Those are the words of Christian Oldendorp, a Danish missionary who visited the Caribbean island of St. Croix in 1767. His account is one of the few Danish historical records of Maronberg, a community of escaped slaves, known as Maroons, in the northwest mountain ranges of the island.

In 1733, the Danish West India-Guinea Company purchased St. Croix from France and quickly expanded the island’s sugar and cotton production. This also meant expanding the slave population to harvest lucrative plantations. But the Danes were never able to fully control the island – or the enslaved. By the end of the 1700s, nearly 1,400 people – more than 10% of the enslaved population – successfully escaped captivity. But where did they escape to? Only recently have researchers started to shed more light on this centuries-old mystery.

As an archaeologist specializing in slavery and resistance, I’ve excavated plantations in the Americas and used geographic information systems to model Maroon escape routes by sea. Recently, I turned my attention to Maroon settlements on land, working with a team of archaeologists to locate Maronberg.

Honoring a legacy

I first learned about Maronberg on a nature tour of St. Croix given by local activist and University of the Virgin Islands professor Olasee Davis in 2016. At that time, I was on the island to excavate a sugar plantation, a project that gave my colleagues and me a unique perspective on the enslaved experience in the Danish-controlled Caribbean.

In August 2025, Davis’ decades-long campaign to create an official heritage sanctuary to protect Maronberg finally came to fruition. The local government purchased 2,386 acres of land to serve as the U.S. Virgin Islands Maroon Territorial Park.

But one problem remains: We have yet to find the physical remains of the settlement. Locating and preserving Maronberg’s historical artifacts and buildings could provide new insight into residents’ way of life and give greater meaning to the sanctuary.

Fortunately, advanced computer modeling and high-resolution maps are helping us get closer to pinpointing the settlement.

Finding what was meant to remain hidden

Many Maroon settlements in the Americas have proved difficult to locate. This makes sense when you consider that their inhabitants were trying to hide from colonial settlers. If the Danes had found Maronberg, they would have either killed its inhabitants or forced them back into slavery.

Runaways tended to settle in areas that were intentionally difficult to access, like remote swampy or mountainous terrain. Houses and other shelters often consisted of semipermanent structures so that Maroons could relocate as needed to avoid detection.

The boundaries of Maronberg and the size of the settlement along the northwestern mountain range remain unknown. Colonial militias attempted periodic raids, but historical records report that they were met with rugged terrain, booby traps and counterattacks.

The missionary Oldendorp wrote: “[The Maroons] keep every approach safe by attempting carefully to conceal small, pointed stakes of poisoned wood so that the unwary pursuer might wound his foot on them and therefore be prevented from continuing the chase as a result of the unbearable pain.”

All those precautions paid off: The Danes were never able to penetrate the Maroons’ encampment.

Using new tech to see 300 years into the past

Recent attempts by researchers to locate Maronberg began in 2007, with more extensive geographic information systems mapping conducted in 2008. These digital, computer-based geographic programs allow researchers to store a range of geological data and model spatial patterns across vast terrains.

Pairing a historical map with a low-resolution elevation map from the U.S. Geological Survey, archaeologist Bo Ejstrud created a predictive model to assess the probable location of the Maroon settlement. He considered elevation, slope and colonial infrastructure to identify the most remote areas of St. Croix with the least visibility from colonial lines of sight.

Back in the 1700s, urban centers accounted for only a small percentage of the overall landmass of the 83-square-mile (215-square-kilometer) island. Much of the land was either plantations or uninhabited forests and mountains. Ejstrud’s model reaffirmed the likelihood of a Maroon settlement in the northwest region. But it left us with a massive survey area. The map also didn’t account for the possibility that the settlement moved over time.

In 2020, I teamed up with archaeologists Steven Wernke, from Vanderbilt University’s Spatial Analysis Research Laboratory, and Lauren Kohut, from Winthrop University’s Geospatial Environmental Modeling Lab. Together, we developed and visualized a more dynamic model using advances in mapping since 2008.

We began by digitizing two of the most detailed colonial maps of St. Croix – one from 1750 and another from 1799. These maps, created by Danish military engineers and surveyors, detail the spread of plantations, roads and settlements over time.

Next, in order to build a digital elevation model of the island’s terrain, we incorporated high-resolution light detection and ranging, or lidar, data collected by the National Oceanic and Atmospheric Administration. Whereas traditional digital elevation models can be skewed by dense vegetation and trees, lidar uses laser pulses that penetrate through the forest canopy to map the Earth’s surface. This technology allows us to analyze some of the most secluded, inaccessible areas on the island. Prior to 2013, lidar was too costly for archaeological research purposes. But these days, it’s built into many cellphones.

By layering these datasets in geographic information systems software, we created a suitability model that estimated where Maroon settlements were most likely to have existed. In addition to isolation and visibility, we also incorporated accessibility to water sources and terrain ruggedness to model the degree of mobility through the landscape.

This approach allowed us to simulate how the opportunities and constraints the landscape offered to people seeking refuge shifted as colonial society grew over time.

Mapping changes

In addition to providing more nuance to the picture of the areas where Maroons potentially settled, our research suggests that the Maroon settlement wasn’t static, but likely waned as colonial infrastructure increased on the island. Our model implies that the area of suitable land for clandestine Maroon communities shrank by more than 90% in just 50 years.

It’s possible that over time there were fewer runaways. More likely, more Maroons left the island by boat for destinations such as Puerto Rico and Tortola.

Where we go from here

Though our findings still don’t provide an exact location for Maronberg, they get us one step closer to locating the physical remains of this centuries-old Maroon community. The next step will be to visit these sites and survey them for evidence of historical settlement. Archaeological research at these sites would help us understand more about the Maroons who turned a rugged landscape into a sanctuary for freedom.

Ultimately, identifying artifacts and historical sites within the newly established U.S. Virgin Islands Maroon Territorial Park would help us develop educational tours and honor the Maroon legacy.

Latin American literature contains warnings for American universities that yield to Trump

As university leaders work to make deals with the Trump administration, many college presidents are at an ethical crossroads. On the one hand, they must do all they can to restore funding for vital research. On the other, they risk ceding to the demands of a president with views that don’t align with their missions.

As the fall semester begins, academic administrators could look to literature for guidance. Latin America’s rich archive of fiction over the past century features this dilemma in numerous stories about living under dictatorships.

Among many others, Peruvian novelist Mario Vargas Llosa, Colombian writer and journalist Gabriel García Márquez and Argentine author Luisa Valenzuela have mined the region’s turbulent political history to explore how authoritarian rulers bend institutional leaders to their will by cultivating fear.

Lessons from the bookshelves

In these works, some threats are more overtly coercive than others.

Vargas Llosa’s “The Feast of the Goat” details how Dominican dictator Rafael Trujillo reportedly fed insubordinate underlings to voracious crocodiles, an image that, for me, has echoes in Florida’s Alligator Alcatraz. In García Márquez’s “The Autumn of the Patriarch,” an illiterate strongman takes over all institutions to such an extreme that “él solo era el gobierno” – he alone was the government.

Yet to me, the greatest danger that Latin American literature foretells for higher education is the insidious way capitulation to authoritarians changes both individuals and institutions.

This is the subject of “The Censors,” a 1976 short story by Valenzuela. Back then, all but four Latin American countries were dominated by authoritarian regimes.

The main character in Valenzuela’s story is an average Joe – aptly named Juan – who writes a letter to his beloved Mariana, now living in Paris. Soon after he mails the letter, Juan is beset by fear that despite its innocuous sentiments, his message will be construed by authorities as subversive. He worries that secret military forces will fly to Paris and kidnap Mariana from her apartment. (Masked men forcing people into unmarked vehicles is a common sight in dictatorships, then and now.)

Juan decides he must “sabotage the machinery, throw sand in its gears.” So he becomes a censor for the regime in hopes of intercepting his own letter as it works its way through the painfully slow Post Office Censorship Division.

University leaders, much like Juan, begin with the best of intentions. They initially collaborate with the government’s demands because they want to protect the university’s mission.

But once the concessions are made, things begin to change.

In “The Censors,” Juan discovers he has a knack for redacting questionable letters. Assigned to a division that checks correspondence for explosives, he watches as a co-worker’s right hand gets blown off. Yet when a colleague tries to organize a demonstration advocating for safer working conditions, Juan reports him to the authorities and is rewarded with a swift promotion.

Juan justifies his opportunism as a one-off rather than a personal transformation: “Una vez no crea hábito” – “One time doesn’t create a habit” – he reassures himself as he leaves his boss’s office.

As he reaches the highest echelons of the censorship authority, Juan’s sense of purpose blurs beyond recognition. He now considers flagging subversive letters and condemning their authors to be “a truly patriotic task, both self-sacrificing and uplifting.”

At this exact moment, Juan encounters his own letter to Mariana. “Naturally,” the narrator declares acidly, “he censored it without regret.” In the last lines of the story, the narrator reveals that Juan was executed the following day.

Juan, Valenzuela concludes with devastating irony, is “one more victim of devotion to his work.”

Universities in the crosshairs

In his zeal to capitulate, Juan deals himself a death blow, and I can’t help but wonder if universities are heading down the same perilous path.

In an official statement, Brown University noted on July 30, 2025, that it will “comply with the Trump administration’s vision” on admissions practices. Likewise, Columbia University has agreed to direct governmental oversight of its Middle East studies department, while the University of Pennsylvania will no longer allow trans women on female sports teams.

At the University of Virginia, where I’m an associate professor of Spanish, President James E. Ryan resigned under intense pressure from the Department of Justice in June 2025.

For most of his seven years in leadership, Ryan set out to make the university more diverse and open doors for first-generation and low- to middle-income students.

By the time of his resignation, however, the university had already yielded to demands from a conservative alumni group to de-emphasize the history of enslavement during campus tours. And it had adopted “institutional neutrality,” meaning it would no longer take a position on, say, mass starvation in Gaza.

In March 2025, the university’s governing board voted to dismantle the university’s diversity, equity and inclusion office at the behest of Virginia Gov. Glenn Youngkin.

Three months later, Ryan was gone.

More to come?

As the White House continues its pressure campaign, academic administrators may face more funding threats in the future. I worry that if humanities programs are cut – the University of Chicago just paused admissions to doctoral programs in literature, philosophy, the arts and languages, citing “this moment of uncertainty” – students will lose the opportunity to be introduced to works like “The Censors.”

Columbia maintains it has safeguarded academic freedom by making a deal. But as Wesleyan University President Michael Roth told PBS, the academic community remains skeptical about the durability of these agreements.

Perhaps some administrators believe, as Juan did, that “one time doesn’t create a habit.”

But higher education, I fear, is being swallowed by its leaders’ “devotion to their work.”

How stripping diversity, equity and inclusion from health care may make Americans sicker

Source: The Conversation – USA (3) – By Abigail Folberg, Assistant Professor of Psychology, University of Nebraska Omaha

President Donald Trump’s administration has dramatically reshaped health and medical research by rolling back federal funding from institutions that have diversity, equity and inclusion initiatives and by cutting federal funding for research projects that the administration considers related to DEI.

As of Aug. 20, 2025, the National Institutes of Health has terminated over 5,100 grants totaling over US$4.4 billion in research funding. Likewise, the National Science Foundation, which seeks among other things to advance the nation’s health, has rescinded over 1,700 research grants totaling over $1 billion in funding.

These terminations have disproportionately affected projects that study the experiences of marginalized groups and funding to scientists from social groups that are underrepresented in academia. The federal judge overseeing a case challenging cuts to NIH grants said that he had “never seen government racial discrimination like this.”

Many Americans may view these cuts to health-related research as disconnected from the health care they receive. However, as a psychologist and a chemical engineer who study how gender and racial inequality affect well-being and the incidence and progression of disease, we believe that these changes will make all Americans less healthy.

Health repercussions for minority groups

The Trump administration’s funding cuts will most directly affect the health of members of marginalized groups, including, but not limited to, people of color, women and people who identify as lesbian, gay, bisexual, intersex and transgender. The website grant.witness.us includes a list of the project descriptions of canceled grants. The NIH grants that were terminated include ones that funded research investigating the effects of food insecurity and stress on prenatal and birth outcomes among women of color, sex differences in major depression, and risk factors for suicidal behavior among gender minority adolescents.

The White House has also indicated that it intends to ax the National Institute on Minority Health and Health Disparities, which funds research on groups that tend to have poorer health outcomes, in its planned reorganization of the NIH.

These cuts will likely make these groups’ health outcomes worse. One of the reasons for these health disparities is that the health experiences and outcomes of members of marginalized social groups, such as women of color, have historically received less attention. Health disparities cannot be closed without high-quality research.

The case of endometrial cancer

One example of a disease where differences in health outcomes vary depending on race is endometrial cancer. The endometrium is an inner layer of the uterus, and endometrial cancer therefore primarily affects women. As we discussed in a 2023 review article, Black women are more likely than white women to have worse disease outcomes and to die from endometrial cancer. Some of the reasons for these disparities are unclear. For example, researchers do not know why Black women are more likely to get the more aggressive of two subtypes of endometrial cancer. This knowledge gap underscores the need to study these disparities.

But many causes of these disparities are known – and they are social in nature. For example, researchers discovered that Black women were less likely than white women to know about the early warning signs of endometrial cancer, such as postmenopausal vaginal bleeding. Black women were, therefore, more likely to be diagnosed later and die from endometrial cancer. Additionally, many Black women use chemical hair straightening kits, or perm kits, which have recently been linked to endometrial cancer incidence.

Also, Black patients and members of other groups, such as LGBTQ people and women, also routinely experience discrimination from health care providers. For example, studies suggest that some providers may fail to provide the best possible medical care and express discriminatory attitudes toward Black and sexual minority patients, which may prompt patients to avoid seeking future medical care. More generally, the stress from experiencing discrimination can also lead to physiological changes in the body that contribute to poorer physical and mental health.

Addressing social factors that influence health

DEI initiatives may address some of these social factors. For example, efforts to promote diversity among medical professionals may be beneficial because patients of color may experience better outcomes when they are treated by doctors who share their racial or ethnic identity, and more diversity among primary care physicians may reduce racial health disparities. Black patients are also more likely to trust their providers when their providers signal awareness of systemic inequality – and trust, in turn, may encourage people to make use of preventive health services such as routine checkups.

Medical care is also supported by scientists from many disciplines who research the progression and treatment of disease. These researchers’ identities may influence what they choose to study and how they choose to study it. DEI initiatives, such as peer-mentoring programs and intentional efforts to recruit diverse faculty, help institutions to recruit and retain people whose backgrounds and experiences are traditionally underrepresented in academia. Better representation across many scientific fields may also contribute to the research and training of physicians and other scientists who contribute to the health of the nation.

Diversity in health care benefits everyone

Slashing support for DEI initiatives in health care as well as funding for minority health is likely to reshape the health of all Americans, not just people of color and others from underrepresented groups.

For example, the government has scrubbed the mention of words that are associated with DEI, such as “women,” “Black” and “bias” from federal agencies and has increased scrutiny of grants submitted to the NIH and the National Science Foundation. Among the canceled grants was research examining women’s reproductive health, which affects both women and anyone who wishes to become a parent, regardless of whether they carry or birth that child.

Other canceled research grants examined ways to reduce the incidence of new HIV/AIDS infections among transgender women and men of color. Although this research specifically examined transgender people, research on reducing the transmission of HIV is a key strategy for eradicating HIV/AIDS, which affects about 1.2 million people in the U.S. and about 40.8 million people worldwide.

Moreover, because trainees from many different research areas were supported by grants that support biomedical researchers from underrepresented groups, canceling those grants has curtailed the study of diseases that affect many people. For example, these cuts have hit research on Parkinson’s disease, which is rising in prevalence and affects more men than women.

Health disparities also have profound economic costs – and poorer care for people from marginalized social groups result in costs that are borne by everyone. A 2018 study, for example, estimated that in 2018 alone, racial health disparities cost society $421 billion to $451 billion in excess medical care expenses, lower labor force productivity and premature death. The same study estimated that health disparities among those who did and did not have a college education cost between $940 billion and $978 billion.

Abundant evidence shows that improving the nation’s health requires medical research and education that broadens participation in science and attends to the health and well-being of all Americans, including those whose experiences were historically overlooked in the biomedical and psychological sciences. In our view, a more inclusive and pluralistic vision of science and health care is the best way to promote better health care for all.

Pregnancy brings unique challenges for people with autoimmune diseases – but with early planning, pregnancy outcomes can be greatly improved

Source: The Conversation – USA (3) – By Kristen Demoruelle, Associate Professor of Rheumatology, University of Colorado Anschutz Medical Campus

Early discussions and proactive planning for pregnancy are critically important for those with autoimmune diseases. d3sign/Moment via Getty Images

Only a few decades ago, a diagnosis of lupus could mean giving up the dream of having children. Women with systemic autoimmune diseases like lupus were warned that pregnancy was too risky – both for them and their unborn babies. Fast forward to today, and the story is remarkably different.

Thanks to scientific research and medical advances, pregnancy outcomes have greatly improved over the past several decades, and the outlook for pregnancy in people with autoimmune disease is more hopeful than ever.

However, pregnant women with autoimmune diseases still face a far higher likelihood of having serious complications, including preterm birth or even fetal loss. So while the outlook has improved, navigating pregnancy with these conditions still comes with a unique set of challenges and considerations. This is due to the medicines used to treat the disease, the effects of inflammation on the body and imbalances of the immune system, including some that researchers like me don’t yet fully understand.

I’m a rheumatologist and biomedical researcher with medical training and expertise in rheumatology and reproductive health. Rheumatology is a medical specialty that treats people with systemic autoimmune and inflammatory diseases, like the ones discussed in this article. We’re sometimes thought of as arthritis doctors, but systemic autoimmune diseases can involve the whole body, and we care for all of those effects.

I think it is essential that women with autoimmune diseases are equipped with a realistic understanding of their potential pregnancy journey – both the advances that have made motherhood more possible for them and the risks that still remain.

Autoimmune diseases disproportionately affect women

Systemic autoimmune diseases are chronic medical conditions in which the immune system, which normally protects the body from infections, mistakenly attacks the body’s own tissues. These conditions can include lupus, rheumatoid arthritis and antiphospholipid syndrome, to name a few.

Some autoimmune diseases attack only one part of the body. For instance, the thyroid is the only part of the body targeted in a disease called Hashimoto’s thyroiditis. But in systemic autoimmune diseases, the immune system can attack multiple parts of the body, like the skin, lungs and kidneys in those with lupus.

Autoimmune diseases disproportionately affect women. Lupus, for instance, occurs nine times more often in women than in men, and rheumatoid arthritis is three times more common in women. Since many women are diagnosed with these conditions in their 20s and 30s, when women are in their prime childbearing years, pregnancy can introduce new and unexpected challenges to their health care.

Increased pregnancy complications

Preeclampsia – a high blood pressure complication of pregnancy – preterm birth and stillbirth all occur at higher rates in women with autoimmune diseases. This is especially true for women with lupus and a condition called antiphospholipid syndrome. Women with these autoimmune disorders are five times more likely to experience these complications.

Autoimmune diseases are also linked to higher rates of miscarriage and postpartum depression.

Some women with lupus and a condition called Sjogren’s syndrome have an antibody in their blood that can cross the placenta and cause a rare but serious congenital heart condition. Studies have also found higher rates of autism spectrum disorders in women with autoimmune diseases.

Testing and early planning can improve outcomes

Fortunately, thanks to advances in research and medicine, doctors and researchers like me now have helpful tools to assess a woman’s individual risk. This allows people with autoimmune diseases to better understand and manage their health before getting pregnant.

Pregnancy and the postpartum period can sometimes lead to remission, which is a time when inflammation and the disease are quiet, and sometimes lead to flares, or flare-ups, when inflammation increases and the disease is very active. Importantly, women who conceive while their autoimmune disease is quiet, rather than during a flare, have healthier pregnancies. By waiting for a time when one’s autoimmune disease is in remission, a woman can improve her chances of a healthy pregnancy.

Certain blood tests can also give clues about a person’s risk for pregnancy complications. For example, a positive test for lupus anticoagulant, a blood test that looks for certain proteins that can increase the risk of blood clots, can identify women at the highest risk for preeclampsia, preterm birth and fetal loss.

Some women also have antibodies that target proteins inside their cells, called Ro, which are often found in people with Sjogren’s syndrome. If a pregnant person has high levels of anti-Ro antibodies, they are at risk for a serious pregnancy complication called fetal heart block. The good news is that certain medications can lower these risks in women who have these antibodies.

Medications and pregnancy

Researchers and rheumatologists like me also better understand how medications affect pregnancy, in both harmful and helpful ways.

Several medications that are commonly used to treat autoimmune diseases can harm a developing baby or reduce fertility. If a pregnancy is being planned, these medications must be stopped ahead of time and replaced with pregnancy-safe medications.

In cases of unplanned pregnancy, stopping potentially harmful medications quickly can be critical. For those not planning pregnancy, using effective birth control is an important safeguard. Notably, contraception choices can also be influenced by a woman’s underlying autoimmune disease and should be discussed with the person’s rheumatologist or other specialists.

On the other hand, some medications can improve pregnancy outcomes in people with autoimmune diseases. For example, a medication called hydroxychloroquine can reduce the risk of anti-Ro antibody-mediated fetal heart block. Low-dose aspirin taken during pregnancy can lower the risk of preeclampsia.

And recently, a study found that a drug named certolizumab improved pregnancy outcomes in women with antiphospholipid syndrome, which is an autoimmune condition with high rates of pregnancy complications.

Historically, pregnant women were excluded from research studies, but this is starting to change, which could lead to safer pregnancies for those with autoimmune disease.

Looking ahead

With all this in mind, it’s important for people with systemic autoimmune disease to talk with their rheumatologist or other specialists when thinking about pregnancy and throughout the process. Planning ahead gives the best chance for a healthy pregnancy.

Still, even with careful planning, autoimmune disease flare-ups can happen during pregnancy, and treating them promptly is important for both the mom and the baby.

Ongoing care after delivery matters, too, as postpartum flares can interfere with a mother’s ability to care for her newborn. Fortunately, there are safe options available to treat flare-ups during pregnancy or breastfeeding.

Talking to your doctor

With better treatments and growing knowledge, most women with autoimmune disease are now having healthy pregnancies and thriving babies. Fertility options like in vitro fertilization are also safe for many with autoimmune diseases.

Some helpful questions to consider asking your rheumatologist include:

  • What should I expect if I want to get pregnant?
  • Is my disease under control enough to try for pregnancy now?
  • Are my current medications safe if I become pregnant?
  • Do I need to stop or start any medications before trying to conceive?
  • What are my chances of having a healthy pregnancy?
  • What are the possible complications I could face during pregnancy?
  • What treatment options would I have if my disease flared up during pregnancy or after delivery?
  • If I need to wait to get pregnant due to active disease, how long should I wait, and what contraception is best in the meantime?

The American College of Rheumatology and the European Alliance of Associations for Rheumatology offer clear, evidence-based recommendations for pregnancy.

There are also clinical tools available to rheumatologists and resources available to patients to help guide safe, personalized reproductive health care.

I believe it’s essential to have a care team that’s comfortable guiding you through these decisions, and it’s always OK to ask questions or explore additional resources.

Why religious groups are pushing for psychedelics as sacrament

Source: The Conversation – USA (3) – By Pardis Mahdavi, Professor of Anthropology, University of La Verne

Texas passed a landmark law in June 2025, supported by former Gov. Rick Perry, that allocates US$50 million to support research on ibogaine, one of the most powerful psychedelics, for treating opioid addiction and treatment-resistant PTSD.

Arizona passed a similar law in May, funding research on ibogaine’s effectiveness for treating veterans and those with traumatic brain injuries.

These laws come on the heels of states such as Oregon, Colorado, Kentucky and Georgia legalizing ketamine – a psychedelic that has been used in emergency rooms as anesthesia – for therapeutic purposes in the past two years.

Psychedelics, broadly defined, are a class of psychoactive substances that alter perception, cognition and mood through their interaction with neurotransmitters such as serotonin.

As a medical anthropologist I have spent the past 25 years studying the rise of alternative approaches to mental health treatments and have specifically focused in the past four years on the impact of psychedelics on consciousness and spirituality.

The push to legalize psychedelics in America is not new. What distinguishes the latest round of advocacy, however, is its backing by a holy trinity of supporters: some scientists, politicians and clergy.

Several religious groups have historically used psychedelics for sacred healing. Some clergy who have been exposed to these medicines in the past few years are advocating their use for gaining mystical insights.

What does the science say?

There are several kinds of psychedelics. Classic psychedelics include compounds such as lysergic acid diethylamide, or LSD; psilocybin – the active component in “magic mushrooms”; and mescaline, which is derived from peyote and San Pedro cacti. Another psychedelic is N,N-dimethyltryptamine, or DMT, found in ayahuasca and other plants.

Beyond the “classic” category, other psychoactive compounds sometimes grouped with psychedelics include substances such as MDMA, a class of psychoactive drugs that can induce feelings of love, empathy and connectedness with others. A 2021 study on MDMA showed a 67% reduction of PTSD symptoms after three sessions of MDMA therapy. While the study had a limited sample size of 104, it marked a turning point in how the psychologists understood MDMA as a potential healing modality.

Dissociative agents such as ketamine, which can produce altered states of consciousness, are also included as a category of their own. Traditionally used as a medical anesthetic, ketamine has more recently gained attention for mental health treatment, particularly for its antidepressant effects.

Derived from the iboga plant native to West Africa, ibogaine induces powerful visions and dreams. It has a long history of being used by traditional healers in villages throughout Africa to treat mental health issues, such as anxiety and depression. A 2022 National Institutes of Health review of 24 studies showed that ibogaine significantly reduced depression, PTSD and opioid addiction in at least two-thirds of the 743 study participants. This mirrors the scientific evidence provided in the 2024 Stanford brain study, which showed an 88% decrease in PTSD symptoms following use of ibogaine in 30 military veterans.

Clergy and psychedelics

Several mental health practitioners and scientists have been staunch advocates of psychedelic-assisted therapy based on this research. What is somewhat new, however, is the addition of a handful of high-profile clergy to the list of supporters.

A recent study published by New York University and Johns Hopkins University highlights a number of religious practitioners, ranging from Episcopal ministers to Catholic priests, rabbis and Zen monks: 24 of the 29 participants made the case that psychedelics can lead to profound spiritual experiences.

A May 2025 article in The New Yorker noted that several of the clergy who participated in the NYU/Johns Hopkins study went on to become vocal advocates of psychedelics as spiritual medicine. While the sample size was small and heavily composed of Christian religious leaders, the findings are noteworthy. Some 96% of study participants described the use of psychedelics as one of the top five “most spiritually significant experiences of their lives.”

An NIH study conducted in 2019 focused on spiritual encounters experienced through DMT, or N,N-dimethyltryptamine. The study revealed that 75% of the 42 participants reported an “intense mystical encounter” and believed that it brought them closer to the divine. They narrated the experience as one in which they saw flashes of white light, heard angelic sounds, felt tingling in their bodies and had an overall sensation of God’s love.

A ‘chairlift to God’

Leaders and members of churches that use psychedelics as “sacrament” describe the role of these substances as facilitating a deeper connection with the divine. The psychedelics are offered at the beginning of weekly services by the religious leader, and then the congregants move into singing, chanting or prayer. Several leaders of such churches whom I have interviewed have described the role of the psychedelics as facilitating a deeper focus on God for longer periods of time.

The Native American Church, which is considered the largest Indigenous church in America and is located throughout the Southwest, has been legally using peyote, a hallucinogen, for services since the 1990s.

The 1994 American Indian Religious Freedom Act allows Native American churches to use and transport peyote, even though it is a Schedule 1 substance, meaning that its use is technically illegal outside of special circumstances as provided by exemptions to the law. Congregants in the church note that they have been using natural plants like peyote for as long as they can remember – even before it was officially legal.

More recently there have been a series of churches opening up across the U.S. that use ayahuasca as their sacrament.

In May 2025, the Gaia Church in Spokane, Washington, became one of the first churches in America to receive the Drug Enforcement Administration exemption for the use of ayahuasca in religious ceremonies. The DEA exemption makes the use of the substances completely legal for all members of the church as long as it is taken as a sacrament and provided by the spiritual leaders.

One shaman who runs an ayahuasca-focused church in Hawaii whom I interviewed last year described psychedelics as a “chairlift to God” because of the numbers of people in his congregation who report seeing, feeling, glimpsing or sensing God after drinking ayahuasca.

“There is no doubt that psychedelics can induce profound spiritual experiences,” one priest who has become a psilocybin advocate told me. “If this is what can bring people back together and back to the church, then harmonizing the ways of the ancients with plant medicines, modern technologies and religion might be the way to heal societal ills.”

Proceeding with caution

Although most classic psychedelics are considered safe and nonaddictive, they also carry some risks. Psychedelic use can induce acute anxiety, cause panic attacks or lead to paranoia. In rare cases, they could lead to psychotic breakdowns and suicidal thoughts, particularly among individuals with a personal or family history of schizophrenia or other severe mental illnesses.

Psychedelics can also temporarily impair judgment and coordination, which may increase the risk of accidents or unsafe behaviors if taken in recreational settings. Risks can also be amplified by uncertain dosage, adulterated substances and the absence of certified and trained facilitators.

Most mental health practitioners and advocates of these medicines suggest that they be taken under the care of medical or spiritual professionals who have trained in administering and facilitating preparation and aftercare for psychedelic use.

Shamans and Indigenous practitioners have long regarded these substances as sacred medicines and used them for healing. Modern-day science is confirming some of their benefits in supporting future treatments of trauma and addiction. Moreover, the mystical experiences that these medicines offer as pathways to connect people to the divine are profound.

When the government can see everything: How one company – Palantir – is mapping the nation’s data

When the U.S. government signs contracts with private technology companies, the fine print rarely reaches the public. Palantir Technologies, however, has attracted more and more attention over the past decade because of the size and scope of its contracts with the government.

Palantir’s two main platforms are Foundry and Gotham. Each does different things. Foundry is used by corporations in the private sector to help with global operations. Gotham is marketed as an “operating system for global decision making” and is primarily used by governments.

I am a researcher who studies the intersection of data governance, digital technologies and the U.S. federal government. I’m observing how the government is increasingly pulling together data from various sources, and the political and social consequences of combining those data sources. Palantir’s work with the federal government using the Gotham platform is amplifying this process.

Gotham is an investigative platform built for police, national security agencies, public health departments and other state clients. Its purpose is deceptively simple: take whatever data an agency already has, break it down into its smallest components and then connect the dots. Gotham is not simply a database. It takes fragmented data, scattered across various agencies and stored in different formats, and transforms it into a unified, searchable web.

The stakes are high with Palantir’s Gotham platform. The software enables law enforcement and government analysts to connect vast, disparate datasets, build intelligence profiles and search for individuals based on characteristics as granular as a tattoo or an immigration status. It transforms historically static records – think department of motor vehicles files, police reports and subpoenaed social media data like location history and private messages – into a fluid web of intelligence and surveillance.

These departments and agencies use Palantir’s platform to assemble detailed profiles of individuals, mapping their social networks, tracking their movements, identifying their physical characteristics and reviewing their criminal history. This can involve mapping a suspected gang member’s network using arrest logs and license plate reader data, or flagging individuals in a specific region with a particular immigration status.

The efficiency the platform enables is undeniable. For investigators, what once required weeks of cross-checking siloed systems can now be done in hours or less. But by scaling up the government’s investigative capacity, Gotham also alters the relationship between the state and the people it governs.

Shifting the balance of power

The political ramifications of Palantir’s rise come into focus when you consider its influence and reach across the government. U.S. Immigration and Customs Enforcement alone has spent more than US$200 million on Palantir contracts, relying on the software to run its Investigative Case Management system and to integrate travel histories, visa records, biometric data and social media data.

The Department of Defense has awarded Palantir billion-dollar contracts to support battlefield intelligence and AI-driven analysis. Even domestic agencies like the Centers for Disease Control and Prevention and the Internal Revenue Service, and local police departments like the New York Police Department, have contracted with Palantir for data integration projects.

These integrations mean that Palantir is not just a vendor of software; it is becoming a partner in how the federal government organizes and acts on information. That creates a kind of dependency. The same private company helps define how investigations are conducted, how targets are prioritized, how algorithms work and how decisions are justified.

Because Gotham is proprietary, the public, and even elected officials, cannot see how its algorithms weigh certain data points or why they highlight certain connections. Yet, the conclusions it generates can have life-altering consequences: inclusion on a deportation list or identification as a security risk. The opacity makes democratic oversight difficult, and the system’s broad scope and wide deployment means that mistakes or biases can scale up rapidly to affect many people.

Beyond law enforcement

Supporters of Palantir’s work argue that it modernizes outdated government IT systems, bringing them closer to the kind of integrated analytics that are routine in the private sector. However, the political and social stakes are different in public governance. Centralized, attribute-based searching, whether by location, immigration status, tattoos or affiliations, creates the capacity for mass profiling.

In the wrong hands, or even in well-intentioned hands under shifting political conditions, this kind of system could normalize surveillance of entire communities. And the criteria that trigger scrutiny today could be expanded tomorrow.

U.S. history provides warning examples: The mass surveillance of Muslim communities after 9/11, the targeting of civil rights activists in the 1960s and the monitoring of anti-war protesters during the Vietnam era are just a few.

Gotham’s capabilities may enable government agencies to carry out similar operations on a much larger scale and at a faster pace. And once some form of data integration infrastructure exists, its uses tend to expand, often into areas far from its original mandate.

A broader shift in governance

The deeper story here isn’t just that the government is collecting more data. It’s that the structure of governance is changing into a model where decision-making is increasingly influenced by what integrated data platforms reveal. In a pre-Gotham era, putting someone under suspicion of wrongdoing might have required specific evidence linked to an event or witness account. In a Gotham-enabled system, suspicion can stem from patterns in the data – patterns whose importance is defined by proprietary algorithms.

This level of data integration means that government officials can use potential future risks to justify present action. The predictive turn in governance aligns with a broader shift toward what some scholars call “preemptive security.” It is a logic that can erode traditional legal safeguards that require proof before punishment.

This short documentary about Palantir includes a former employee expressing concern about how algorithms are transforming government.

The stakes for democracy

The partnership between Palantir and the federal government raises fundamental questions about accountability in a data-driven state. Who decides how these tools are used? Who can challenge a decision that was made by software, especially if that software is proprietary?

Without clear rules and independent oversight, there is a risk that Palantir’s technology becomes normalized as a default mode of governance. They could be used not only to track suspected criminals or terrorists but also to manage migration flows, monitor and suppress protests, and enforce public health measures. The concern is not that these data integration capabilities exist, but that government agencies could use them in ways that undermine civil liberties without public consent.

Once put in use, such systems are hard to dismantle. They create new expectations for speed and efficiency in law enforcement, making it politically costly to revert to slower, more manual processes. That inertia can lock in not only the technology but also the expanded scope of surveillance it enables.

Choosing the future

As Palantir deepens its government partnerships, the issues its technology raises go beyond questions of cost or efficiency. There are civil liberties implications and the potential for abuse. Will strong legal safeguards and transparent oversight constrain these tools for integrated data analysis? The answer is likely to depend on political will as much as technical design.

Ultimately, Palantir’s Gotham is more than just software. It represents how modern governance might function: through data, connections, continuous monitoring and control. The decisions made about its use today are likely to shape the balance between security and freedom for decades to come.

When federal courts fail to punish lawyers for potential misconduct, states can step in

In early August 2025, a federal appeals court in the District of Columbia stopped efforts by federal trial judge James Boasberg to consider whether to hold Trump administration lawyers in contempt of court.

In April, Boasberg had concluded there was probable cause to hold government lawyers in contempt for defying orders he had issued related to the deportation of migrants to a prison in El Salvador.

The appellate court’s ruling found that such contempt proceedings could not go forward on various technical grounds.

As someone who teaches and writes on legal ethics, I believe the questions surrounding whether administration lawyers violated Boasberg’s rulings still can be answered thanks to state bodies that license lawyers to practice law.

State discipline

Boasberg has previously indicated that he might refer lawyers who have defied his orders to state authorities.

This is an option because the U.S. legal profession is largely licensed and regulated at the state level and, in the case of Washington, D.C., by the local D.C. courts. It’s in proceedings before disciplinary bodies – such as California’s State Bar Court, New York State’s attorney grievance committees and the Board on Professional Responsiblity in D.C., for example – where lawyers have to answer for charges that they have violated their professional code of ethics. That includes lawyers in the federal government.

Egregious violations of professional obligations, such as fabricating or destroying evidence or lying to a court, can result in a lawyer being suspended from practice and even disbarred completely.

These systems are a critical component of the checks on the U.S. legal system. It ensures that lawyers uphold their professional obligations as they pursue their clients’ rights.

The U.S. legal system is adversarial in nature. That means lawyers engage in zealous advocacy when they strive to advance the interests of their clients. Lawyers then resolve their disputes within that adversarial system, but even the advocates in that system have to follow its rules of engagement.

A central tenet of that system is that lawyers may not act unethically by abusing their knowledge of the system to illegally advance their clients’ interests – and their own.

This type of abuse of the system occurred when lawyers tried to overturn the results of the 2020 U.S. presidential election, filing dozens of unsuccessful cases to seek to change the election’s outcome. And they made spurious legal arguments in an attempt to halt Congress’ certification of the final vote in the Electoral College.

Some of the lawyers who took part in those efforts have been punished and disbarred for their actions, including former New York City Mayor Rudy Giuliani, who lost his license to practice law in New York and Washington, D.C.

Recently, lesser-known lawyers such as John Eastman and Jeffrey Clark, both involved in the effort to prevent the transfer of presidential power after Trump lost his reelection bid, have also faced disciplinary charges. While these processes have not yet completely run their course, state bodies have recommended that each should lose his license to practice law.

Disciplinary bodies and the rule of law

The state bodies that govern the practice of law, and which license lawyers who practice even in the federal courts and the federal government, serve as a critical check on unprofessional conduct by lawyers.

State proceedings are no panacea, however. They can take time. That’s evident in the cases against Eastman and Clark, which are still working their way through the systems in the District of Columbia, in the case of Clark, and California, in Eastman’s case, for events that happened in late 2020 and early 2021.

And there is always the risk that adversaries can start an escalating war of tit for tat, regardless of whether such complaints have merit.

The Trump administration targeted private law firms for punishment through a series of executive orders that, for example, sought to revoke the firms’ security clearances and bar their lawyers from entering federal buildings. Although all the private law firms that challenged the executive orders issued against them have succeeded in blocking them, the Trump administration has also recently filed ethics charges against at least one of the lawyers involved in a lawsuit against it.

The Trump administration has also instituted a complaint against Boasberg with a federal body that oversees judicial ethics. And just the threat of a complaint, even a baseless one, can certainly have a chilling effect on administration critics, making them less likely to take action in the future.

Sociologist Eliot Freidson notes that one of the hallmarks of a profession is that its members care more about the opinion of their peers than the opinion of the general public. Because professionals should always care about their professional reputation, they should fear taking actions on behalf of a client – no matter who that client is – that exceed the rules that govern the profession. That includes defying court orders, lying on behalf of a client, or making baseless legal arguments.

If professional reputation alone is not enough to prevent such misconduct, the specter of losing the ability to practice, or even the fear of coming before an ethics body, might cause enough lawyers to think twice before they engage in acts that exceed the bounds of permissible, zealous advocacy.

While courts are sometimes where lawyers are sanctioned for improper conduct, including for contempt of court, they are not the only site where attorneys can face discipline for unprofessional conduct.

State ethics bodies have a critical role to play in preserving the rule of law, at least with respect to the conduct of lawyers they oversee.

And if Boasberg, any other judge, or a litigant wants to make referrals to such state institutions when lawyers seek to abuse the system, those bodies certainly have an important role to play in ensuring the legal profession maintains high standards of professionalism and the proper functioning of that system in a manner that comports with the rule of law.

When surgical tools don’t fit: how gender bias in design puts women surgeons at risk

Source: The Conversation – UK – By Gráinne Tyrrell, Doctoral Researcher in Biomedical Device Design, School of Architecture and Product Design, University of Limerick

“If you can’t handle this, you’ll never keep up with your peers.”

That’s what a young vascular surgeon in training reported hearing from a senior colleague during interviews for our study, after she needed two hands to hold a medical device her male peers could operate with one.

Another cardiologist, more than ten years into her career, must regularly hand over part of a procedure because she doesn’t have the grip strength for a particular surgical task. The problem isn’t her skill, focus, or stamina – it’s that the tools were never built for her hands.

Stories like these are sometimes misused to reinforce outdated stereotypes: that women aren’t physically capable of performing certain high-skill roles like heart surgery.

In reality, women surgeons are often working harder – and sometimes risking their own health – to achieve the same results as their male colleagues. The barrier isn’t ability. It’s the long shadow of gender bias in both medicine and design.

Our research team is working to change that. We’ve developed a test rig equipped with sensors and 3D scanning technology to capture precise measurements of grip strength and hand size across a variety of simulated surgical scenarios. So far, we’ve gathered data from 42 cardiologists and vascular surgeons worldwide.

The study involved 24 women vascular surgeons from across the globe, the response was overwhelmingly positive. Many participants shared personal accounts of the strain they endure, describing aching wrists and fear of long-term joint issues – all exacerbated by tools that demand more strength than their bodies can comfortably deliver. For some, the motivation to take part was personal: they want the next generation of surgeons to face fewer barriers.

This data is already being used to inform the design of new cardiovascular devices. Handles are being resized to fit a wider range of hand shapes, and the grip strength required to operate them is being lowered. The aim is simple but critical: reduce injury risk, improve surgeon wellbeing and extend careers.

Built for men, used by everyone

The operating theatre is full of devices designed to fit the “average” surgeon and, for decades, that average has been male. Handle diameters tend to be optimised for larger hands, while buttons and sliders are calibrated to force ranges comfortable for male grip strength.

In vascular and cardiac surgery, precision and power go hand in hand. These procedures require surgeons to maintain awkward positions for extended periods, often in high-pressure situations. Even without design flaws, the risk of muscle and joint strain is significant. But when a handle is too big to grip securely, or a control requires more force than a surgeon can comfortably exert, that risk increases sharply and disproportionately for women.

The impact isn’t only on the surgeon. Fatigue, strain and discomfort can affect concentration and precision, which in turn can influence patient outcomes. In a profession where the margin for error is vanishingly small, ergonomics aren’t a luxury — they’re a safety requirement.

When engineers develop new biomedical devices, they rely on design guidance: technical data on ideal handle sizes, optimal button placement and the comfortable grip force a surgeon should be able to apply.

But these guidelines are built on incomplete data. Historically, women were excluded from research studies, meaning their measurements never made it into the datasets that shape design.

Even when designers look for female-specific data, there either are no data or the sample sizes in studies are very small. One common shortcut is to scale down men’s measurements by 30-40% to “estimate” women’s — a crude approach that doesn’t reflect real-world variation in hand anatomy or grip strength.

The problem isn’t just gender. Ethnicity and age matter too. People of colour have long been underrepresented in health research, compounding the challenges faced by women of colour. The differences can be striking: the average grip strength of a European man is about 49kg, while for an Asian woman it’s around 24kg — yet both may be expected to perform identical surgical tasks with identical tools.

A changing profession needs changing tools

In 2025, women made up the majority of doctors in the UK for the first time — a milestone that signals a profession in transition. But the tools they will use are still rooted in outdated assumptions. The lack of inclusive design isn’t just an equity problem. It’s a practical one, affecting career longevity, workplace safety and ultimately patient care.

Calls to improve ergonomics for women in surgery have been growing louder. Professional organisations, research groups and individual surgeons have all pushed for better-fitting, more adaptable tools. Yet progress has been slow, partly because gathering detailed ergonomic data has traditionally been time-consuming and expensive.

New technologies are changing that. With 3D scanning, advanced sensors, and more sophisticated modelling, it’s now possible to collect accurate, relevant data far more efficiently. This opens the door to design that accounts for the diversity of the surgical workforce — not just in gender and ethnicity, but in body size, strength and working style.

By integrating grip strength and hand size data from a truly representative group of surgeons, designers can move away from the “one-size-fits-all” mindset that has dominated for decades. Lowering the physical demands of surgical tools won’t just help women – it will improve comfort for all surgeons, from smaller men to older practitioners whose grip strength changes over time.

Heart surgery techniques have advanced rapidly in recent years, driving remarkable innovation and design. However, while technological progress has surged ahead, the data guiding these designs remains outdated and exclusionary, oftentimes leaving women in surgery an afterthought.

As today’s operating rooms evolve in diversity, we’re advocating for surgical instrument design to evolve with it – ensuring inclusivity is built into every medical device.

‘Phubbing’: why ignoring your partner for your phone infuriates certain people – and causes them to retaliate

Source: The Conversation – UK – By Claire Hart, Associate Professor of Psychology, University of Southampton

Picture this: you’re out for dinner with your partner. The food arrives, the conversation flows – and then their phone buzzes. They glance down, smile faintly and start typing. You sit there, fork in hand, suddenly invisible.

That moment has a name: phubbing, a mash-up of “phone” and “snubbing.” It’s become an almost inevitable feature of modern relationships, as smartphones claim a place at the table – sometimes literally.

You might think of phubbing as a minor irritation, but our research shows it can erode relationship quality, dent self-esteem, stir up resentment and even trigger retaliation. And some people are far more sensitive to it than others.

Using a daily diary study, we tracked 196 people over multiple days, asking them to report how much they felt phubbed by their partner, how they reacted and how they felt afterwards.

The pattern was remarkably consistent. On days when people felt more phubbed, they reported lower relationship satisfaction, worse mood and more anger or frustration.

Phubbing can make the “phubbee” feel excluded, less important and less connected. This fits with equity theory in psychology – relationships feel better when both partners invest equally. If your partner is focused on their phone instead of you, it can signal unequal investment.

Individual differences

Not everyone experiences phubbing the same way. In our 2025 study, published in the Journal of Personality, we found that attachment style – the habitual way people think and feel about relationships – played a big role.

People higher in attachment anxiety – who fear abandonment and crave reassurance – reacted more strongly when phubbed. They reported more depressed mood, lower self-esteem and greater resentment. They were also more likely to retaliate.

Those higher in attachment avoidance – who are uncomfortable with closeness – didn’t report their relationship satisfaction drop as sharply due to phubbing, but they still sometimes retaliated, often by picking up their own phone to seek approval and validation from others when their partner wasn’t meeting these needs.

Narcissism can also play a role. People with high levels of narcissism generally like being the centre of attention, but they may go about it in different ways. In another 2025 study, we examined two sub-types of narcissism: narcissistic rivalry (being antagonistic, insecure and status-defending) and narcissistic admiration (being self-promoting and charm-driven).

We found that people higher in narcissistic rivalry reported lower self-esteem, higher anger and more conflict – whether phubbed or not. When phubbed, they were more curious about what their partner was doing, but also more likely to retaliate out of revenge or to gain approval from others.

People higher in narcissistic admiration tended to have higher relationship satisfaction and wellbeing overall. When phubbed, they were more likely to engage in conflict with their partner than retaliation.

Phubbing as a tit-for-tat game

In our earlier 2022 study, we looked more closely at the type of behaviour phubbed partners engaged in. Common responses included ignoring the phubbing, feeling resentful, asking about the phone use or directly confronting the partner. But one of the most frequent, and telling, responses was retaliation – picking up their own phone and doing the same.

When we asked why people retaliated, three main motives emerged. One was revenge, to “teach the partner a lesson”. The other was seeking support, turning to others for connection when the partner seemed unavailable. And a third was seeking approval – posting on social media or messaging to get validation from others. Boredom was also sometimes mentioned, but it was far less common.

Phubbing might seem trivial – after all, we all check our phones. But in relationships, it can act as a micro-rupture in connection. These small moments can accumulate, creating a sense that your partner’s attention is elsewhere and that you’re less valued.

For people who are already sensitive to signs of rejection – like those high in attachment anxiety or narcissistic rivalry – the impact can be magnified. They may interpret phubbing as a deliberate slight, rather than a mindless habit. This can set off cycles of conflict or withdrawal.

How to break the phubbing cycle

If you’ve ever been accused of phubbing, it doesn’t mean you’re a bad partner, but it might mean your habits need attention.

Simple steps can help protect relationship quality can include creating “phone-free” zones during meals or before bed. It could also be useful to acknowledge the interruption if you must check your phone – explaining why and returning your attention quickly.

Ideally, couples should discuss phone boundaries openly so both partners feel respected. If you’re the phubbee, recognising your own triggers can help. If phubbing hits a deep nerve, it may reflect earlier experiences of feeling ignored or undervalued. Perhaps your partner checking their phone isn’t about your inadequacy but rather about having a bad habit that’s hard to break.
Knowing this can help you respond in ways that repair connection rather than escalate conflict.

Ultimately, smartphones aren’t going away and neither is phubbing. But our findings suggest that the small, everyday choice to be present with your partner matters more than you might think. Put simply, when you put down your phone, you pick up your relationship.

Scientists have been wrong about phantom limbs for decades – new study

Source: The Conversation – UK – By Malgorzata Szymanska, PhD Candidate, Cognition and Brain Science, University of Cambridge

22ImagesStudio/Shutterstock.com

Inside every human brain lies a detailed map of the body, with different regions dedicated to different body parts – the hands, lips, feet and more. But what happens to this map when a body part is removed?

For decades, scientists believed that when a body part is amputated, the brain’s body map dramatically reorganises itself, with neighbouring body parts taking over the area once represented by the missing limb.

This idea of large-scale brain reorganisation became a central pillar of what neuroscientists call adult brain plasticity: the ability of the brain to change its structure and function in response to injuries, new experiences or training.

Our new study, published in Nature Neuroscience, shows the opposite is true: the brain’s body map remains strikingly stable, even years after amputation.
To test what happens in the brain after a person loses a body part, we took a unique approach.

Working with NHS surgeons, we followed three adult patients who were preparing to undergo lifesaving arm amputations for medical reasons, such as cancer or severe problems with blood supply. We scanned their brains with functional magnetic resonance imaging (MRI) before the amputation and repeatedly afterwards – in some cases for as long as five years.

During the MRI scans, we asked patients to move different body parts: tapping their individual fingers, curling their toes or pursing their lips. This allowed us to map brain activity and to construct the brain’s body map.

After the surgery, we repeated the scans, this time asking them to move their missing (phantom) fingers. Phantom movements are not imaginary: most amputees continue to feel vivid sensations of their missing limbs, even though they are physically no longer there. Doing so gave us a rare opportunity to directly compare the brain’s hand map before and after amputation in the same person.

We discovered that, across all three patients, the map of the hand in the brain remained remarkably unchanged and did not get overwritten by other body parts, such as the face. This neural stability helps explain why so many amputees continue to feel their missing limbs so vividly.

For most amputees, however, phantom sensations are not neutral sensations; they are painful and described as burning, stabbing or itching. For years, the dominant explanation for these painful sensations came from the idea that the brain’s body map has reorganised itself. In turn, this theory inspired therapies such as mirror box therapy, virtual reality training, or sensory-discrimination exercises, all aimed at fixing supposedly broken maps.

Mirror-box therapy explained.

Our findings show the brain’s body map is not broken. This helps explain why these therapies consistently fail to outperform placebo treatments in clinical trials. If the map remains intact, trying to fix it is a dead end.

The real culprit

Instead, our results suggest we should look elsewhere, for example, in the nerves that are cut during surgery. Severed nerves can form tangled clusters that misfire signals back to the brain. New amputation surgical techniques are being developed to preserve nerve signalling and maintain stable connections to the brain.

Our findings have important implications for developing prosthetic limbs and brain-computer interfaces. Invasive next-generation brain-computer interfaces can tap directly into the preserved map of the amputated body part to decode what movements are being attempted or even deliver electrical stimulation to the map to enable amputees to feel their missing limb.

These technologies are in development and could, one day, restore natural and intuitive control and sensations of a prosthetic limb, by using the preserved body map.

Our results show that our brains have a resilient model of the body that maintains the representations, even when the sensory input is lost. For amputees, this means that the missing limb lives on in the brain, sometimes as a source of discomfort, but also as a resource for future technologies to use.
