What began as a straightforward question from one water-quality advocate has morphed into a high-stakes battle over an oil pipeline at the highest levels of the U.S. government – with implications that go far beyond the fate of a technical legal conflict.

The question arose after a 2010 Enbridge Energy oil spill in Michigan. The advocate asked what other Michigan waterways were at risk from crude oil spills. But in the wake of, among other issues, two ships doing damage to an underwater section of another Enbridge oil pipeline, the conflict has now come all the way to the U.S. Supreme Court.

On Feb. 24, 2026, the justices will hear oral arguments and thereafter deliberate about the future of Enbridge Energy’s Line 5 oil pipeline, which runs through Michigan and Wisconsin.

As a water policy scholar with a focus on the Great Lakes, I have participated directly in the Line 5 debate as a gubernatorial appointee to an advisory board, as well as analyzed its implications. I see this moment in the Supreme Court as one layer of a complex debate that Line 5 has stirred up about states’ rights, Indigenous rights and the future of the fossil fuel economy.

Enbridge Energy vs. Dana Nessel

The actual issue in front of the Supreme Court is procedural: In 2019, Michigan Attorney General Dana Nessel sued Enbridge in a Michigan state court, seeking to shut down the pipeline, alleging “violations of the public-trust doctrine, common-law public nuisance, and the Michigan Environmental Protection Act.” Federal law allowed Enbridge to seek to move the case to federal court within 30 days of the initial filing.

Enbridge did not do so, but the Canada-based multinational company has since argued that it still should be allowed to deal with the case in federal court, as it is doing in a similar case brought by Michigan Gov. Gretchen Whitmer in 2020.

The specific question before the Supreme Court is a very technical legal one: Even though Enbridge failed to request the move to federal court in a timely way, should that prevent Enbridge from moving it later?

A sensitive waterway

There is no debate that Line 5’s crossing of the Straits of Mackinac – which separate Michigan’s Upper and Lower Peninsulas right where Lakes Michigan and Huron meet – lies within Michigan’s territorial boundaries.

The lawsuits from Nessel and Whitmer are attempting to stop Enbridge from operating the pipeline in this sensitive area of the Great Lakes.

The risks became clearer to the public when a ship’s anchor struck the underwater pipeline in 2018 and another ship damaged one of the pipe’s supports in 2020. In the 2018 incident, some fluid – not crude oil – leaked into the lake water.

But Enbridge is refusing to shut the pipeline down. The company says the dispute belongs in federal court because state laws and regulations generally do not apply to this pipeline, which carries mostly Canadian oil to mostly Canadian refineries, using Michigan and the Great Lakes as a shortcut. Enbridge maintains that a treaty with Canada supersedes state authority.

The ruling from the Supreme Court will likely be narrow and procedural. However, all parties seem to agree that the decision will also have much wider consequences, including being a key determinant and signal of states’ rights to protect their waterways and other natural resources in the face of industry opposition.

Bad River Band vs. Enbridge Energy

Meanwhile, in Wisconsin, the Line 5 oil pipeline passes through the reservation of the Bad River Band of Lake Superior Chippewa, and the pending legal outcome in a separate federal court case is well beyond procedural.

The band revoked Enbridge’s easement in 2013, but Enbridge has refused to remove the pipeline, so – after years of failed negotiations – the Bad River Band sued in 2019.

U.S. District Judge William Conley ruled in 2023 that Enbridge had been trespassing for 10 years and awarded US$3 million in damage payments. Conley gave Enbridge until June 2026 to find an alternative route around the Bad River Band’s land, or shut the pipeline down.

As this date approaches with no clear resolution in sight, the Trump administration joined Enbridge in seeking to reverse that decision and keep Line 5 open. While Conley’s decision is being contested by both Enbridge and the Bad River Band in an appeals court one level below the U.S. Supreme Court, the status of the pipeline during this legal process is very much in question.

Line 5 cannot operate without the Bad River Band reservation section, but the deeper issue is about Indigenous peoples’ rights to control their own lands and future on reservations. If Enbridge wins, many analysts believe that Indigenous rights to self-determination on reservations will be significantly eroded.

Attempts to reroute

Enbridge has a two-pronged strategy to save Line 5 from decommissioning: fight in the courts against the state of Michigan and the Bad River Band, while simultaneously working to reroute the pipeline around these problematic areas.

In the Straits of Mackinac, that means attempting to put Line 5 in a tunnel underneath Lake Michigan. This requires federal permits – which will likely be issued soon – as well as state permits. The permission issued by the Michigan Public Service Commission to build the tunnel is being challenged in the Michigan Supreme Court, while advocates are pressuring Whitmer not to issue another state permit that is also required.

The situation is similar in Wisconsin, where federal permits for rerouting the pipeline outside the reservation – but not beyond the watershed serving the Bad River Band’s land – were issued in October 2025 by the Trump administration. The state permit is caught up in legal and political challenges.

In each case, the immediate issue is about the direct environmental impacts of the projects. But also in each case, the underlying battle is about the long-term effects of projects involving fossil fuels. Environmental advocates want the state and federal agencies to consider the permits in light of the potential for more climatic, health and environmental damage from burning the oil the pipeline carries. Enbridge and its allies want to focus narrowly on local ecological impacts and not on the larger debate about the future of fossil fuels.

The bigger debate

As the highest court in the land considers what some might see as a very mundane and localized issue, I believe it’s useful to peel back the layers and see deeper meaning. Jeffrey Insko, an American studies professor at Oakland University and tireless chronicler and analyst of the Line 5 saga, summarizes this depth well:

“If shutting down Line 5 were about nothing more than getting an aging pipeline out of the water, if it weren’t about addressing the climate crisis, about reducing fossil fuel consumption, about a habitable future, about cultivating better relations with the more-than-human world, about respecting Indigenous rights and lifeways, it wouldn’t be a movement worth having. It would just be a technical problem with a technical solution, one that basically accepts the way things are. But shutting down Line 5 is ultimately a step toward changing the way things are.”

The Supreme Court’s ruling may be on technical grounds, but its repercussions could be very wide indeed.

Artists and writers are often hesitant to disclose they’ve collaborated with AI – and those fears may be justified

Source: The Conversation – USA (2) – By Joel Carnevale, Assistant Professor of Management, Florida International University

In a recent survey of more than 2,500 creative professionals, 83% reported using AI in their work. EuroChild/iStock via Getty Images

Generative artificial intelligence has become a routine part of creative work.

Novelists are using it to develop plots. Musicians are experimenting with AI-generated sounds. Filmmakers are incorporating it into their editing process. And when the software company Adobe surveyed more than 2,500 creative professionals across four continents in 2024, it found that roughly 83% reported using AI in their work, with 69% saying it helped them express their creativity more effectively.

The appeal is understandable. Emerging research shows that generative AI can support the creative process and, at times, produce outputs that people prefer to work made by humans alone.

Yet there’s an important caveat that my colleagues and I have recently begun to explore in our research: Positive views of creative work often shift once people learn that AI was involved.

Because generative AI can produce original content with minimal human input, its use raises questions about quality, authorship and authenticity. Especially for creative work closely tied to personal expression and intent, AI involvement can complicate how audiences interpret the final product.

Organizational behavior researchers Anand Benegal, Lynne Vincent and I study how people establish, maintain and defend their reputations, particularly in creative fields.

We wanted to know whether using AI carries a reputational cost – and whether established artists are shielded from the backlash.

No one is immune

When we set out to examine these questions, two competing possibilities emerged.

On one hand, individuals with strong reputations are often granted greater latitude. Their actions are interpreted more favorably and their intentions given the benefit of the doubt. So established artists who use novel technologies like AI may be seen as innovative or forward-thinking, while novices are viewed as dependent or incompetent.

On the other hand, established creators may be held to higher standards. Because their reputations are closely tied to originality and personal expression, AI use can appear inconsistent with that image, inviting greater scrutiny rather than leniency.

To test these competing possibilities, we conducted an experiment in which participants listened to the same short musical composition, which was described as part of an upcoming video game soundtrack.

For the purposes of the experiment, we misled some of the participants by telling them that the piece had been written by Academy Award–winning film composer Hans Zimmer. We told others that it had been created by a first-year college music student.

Across the experimental conditions, some participants were informed that the work was created “in collaboration with AI technology,” while others received no such information. We then measured changes in participants’ perceptions of the creator’s reputation, perceptions of the creator’s competence and how much credit they attributed to the creator versus the AI.

Our results showed that the creator’s existing reputation did not protect them: Both Zimmer’s reputation and that of the novice took a hit when AI involvement was disclosed. For creators considering whether their past success will shield them, our study suggests this might not be the case.

Credit where credit is due?

That said, reputation was not entirely irrelevant – it did shape how evaluators interpreted the creator’s role in the work.

The preexisting reputations of established creators did provide a limited advantage. When we asked participants to indicate how much of the work they attributed to the human creator versus the AI, evaluators were more likely to assume Zimmer had relied less on AI.

In other words, an artist’s prior reputation shaped how people judged authorship, even if it didn’t shield them from reputational damage.

This distinction points to an important implication. The backlash may not stem simply from the presence of AI but from how observers interpret the balance between human contribution and AI assistance.

At what point does collaborating with AI begin to be perceived less like assistance and more like handing over control of the creative process? In other words, when does AI’s role become substantial enough that it is seen as the primary author of the final product?

For instance, a composer might use AI to clean up background noise, adjust timing or suggest alternative harmonies – decisions that refine but do not fundamentally alter their original work. Alternatively, the composer might ask AI to generate multiple melodies, select one they like and make minor adjustments to tempo or instrumentation.

Our study did not vary the degree of AI involvement; participants were told only that AI was used or not mentioned at all.

But the findings suggest that how much AI is used – and how central it appears to the creative process – matters. For creators and organizations, the question may not be whether AI is involved but whether audiences are made aware of the extent of its involvement.

To disclose or not to disclose?

A practical question that naturally follows is whether creators should disclose their AI use.

The New York Times recently reported that some romance novelists were quietly incorporating AI tools into their writing process without disclosing it to readers. This reluctance appears to be widespread: A 2025 workplace survey found that nearly half of employees conceal their use of AI tools, often out of concern that others will view them as cutting corners or question their competence.

Is silence strategically wiser than transparency?

In our first experiment, the composer’s work either mentioned AI collaboration or didn’t mention AI at all.

But we went on to conduct a second experiment to examine disclosure more directly. This time, participants evaluated an employee at an advertising agency.

Everyone first learned that this employee had a strong reputation for creativity. Then, depending on the version of the scenario they saw, the employee either openly said they used AI to help with their creative work; said they used AI only for administrative tasks, such as scheduling meetings; explicitly said they avoided using AI because creativity should come from one’s own thoughts and experiences; or said nothing about AI at all.

This allowed us to see how both using AI and how that use was disclosed influenced judgments of the employee’s creativity and reputation.

The results were clear in one respect: Disclosing AI use harmed the employee’s reputation.

Just as importantly, explicitly stating that AI was not used did not improve evaluations. In other words, there was no reputational advantage to publicly distancing oneself from AI. Staying silent led to evaluations that were at least as favorable as explicitly saying no AI was used.

Our findings suggest that disclosure decisions are asymmetric. For creators who use AI, transparency carries costs. For those who abstain, making clear that they didn’t use AI doesn’t confer an advantage over remaining silent.

Debates over disclosure of AI use in creative fields will continue to be hotly debated. But from a reputational standpoint – at least for now – our findings suggest that disclosing AI use carries costs.

Florida’s proposed cuts to AIDS drug program threaten patient care and public health

More than 128,000 Floridians are living with HIV. The state has the second-highest rate of new HIV diagnoses after Georgia, with approximately 4,500 new diagnoses in 2023, the most recent year for which data is available.

But access to treatment could be in jeopardy if potential budget cuts, announced in January 2026 by the Florida Department of Health, are enacted.

These changes, set to go into effect on March 1, would cut funding for the state’s AIDS Drug Assistance Program, which helps more than 31,000 Floridians with HIV/AIDS afford care.

I am an emeritus professor of medicine and a practicing clinician in the Tallahassee area who specializes in HIV/AIDS treatment. Many of my patients have been treated through this state program over the past 17 years, so I am deeply concerned about threats to its funding.

Funding access to care

Since its creation in 1996, the Florida AIDS Drug Assistance Program has been funded through the Ryan White CARE Act, which Congress passed into law in 1990. The law ensures people with HIV have access to clinical care, housing support, nutrition, case management, and behavioral and substance use care. Most importantly, it guarantees access to medications to treat HIV and its complications.

More than half of those served by the Florida AIDS Drug Assistance Program earn less than US$22,024 per year, which is 138% of the federal poverty level. While researchers can’t say exactly how many lives have been saved by this program, modeling studies have determined that AIDS drug assistance programs across the U.S. are cost-effective.

But the Florida Department of Health says that it is facing a $120 million budget shortfall, and that the federal Ryan White funds are no longer enough to keep the program going without major cuts to services.

Loss of care and insurance

Currently, the program provides access to medication for low-income, HIV-positive Floridians either by directly giving them prescription medications or by paying for insurance coverage for them that includes HIV medications.

The proposed cuts would stiffen the eligibility requirement for the program from earning 400% of the federal poverty level or below, about $88,000 per year, down to 130% or below, about $21,000 per year. This would immediately remove financial support used by about 16,000 patients to access lifesaving medications.

The cuts would also stop program funds from being used to purchase health insurance for eligible patients. The Department of Health has also proposed changing which drugs the program can cover, removing the recommended and most commonly prescribed drug for treating HIV, Biktarvy.

Without access to insurance coverage and medication, these patients face worse health outcomes, and HIV transmission is likely to increase. Ultimately, this would lead to higher health care costs in Florida and more deaths from HIV/AIDS.

Pushing back

AIDS Healthcare Foundation, a national HIV advocacy and provider network, is suing the Florida Department of Health to require that it go through the normal rulemaking process to make changes to the program. Florida statute requires that substantive changes to a program undergo a process of public announcement, followed by a public comment period, before the change is enacted, which did not happen in this case.

An administrative judge has approved an expedited hearing for the lawsuit and will issue a ruling before March 1.

The foundation has also filed a second suit to determine the cause of the Department of Health’s $120 million budget shortfall.

Meanwhile, in the state legislature, both the Florida Senate and House have attempted to include additional funding for the program in their respective budget proposals. But the final budget won’t be voted on until later this March, and Gov. Ron DeSantis has line-item veto authority.

For now, I, along with other health care providers, am scrambling to ensure that patients do not lose access to their medications. We worry that if the drug assistance program is cut, Florida could see a return to the days of increasing HIV-related complications, hospitalizations and deaths.

Why standing in solidarity with immigrants is an act of accompaniment in Catholic philosophy

Source: The Conversation – USA (3) – By Kristy Nabhan-Warren, Elizabeth Kahl Figge Chair in Catholic Studies, University of Iowa

In Portland, Oregon, people wearing inflatable frog costumes – The Portland Frog Brigade – danced outside immigration offices. In Chicago, parents and neighbors walked children to and from school, forming “magic schoolbuses” for families who feared detention.

Thousands of Americans have taken to the streets since fall 2025 to protest against U.S. Immigration and Customs Enforcement’s tactics. These public demonstrations include the more familiar-looking protest signs and chanting, as well as other everyday ways of showing solidarity with minority groups being targeted.

The Americans taking part come from many different faith traditions, and none. But this type of solidarity reminds me of “accompaniment,” a concept I study as a scholar of American Catholicism and Roman Catholicism more broadly.

The idea of accompaniment is rooted in modern Catholic social thought. It was first coined by the late Pope Francis in his 2013 Apostolic Exhortation “Evangelii Gaudium,” or “Joy of the Gospel.”

Accompaniment and its history

Apostolic exhortations are letters written by popes that urge Catholics and non-Catholics alike to demonstrate their faith in everyday actions such as caring for neighbors, the poor and the dispossessed. They also respond to specific issues and challenges of the particular time, such as famine, war and poverty.

Francis penned his call to action soon after he became the pope in the midst of escalating global humanitarian and refugee crises – notably, the death of thousands of migrants crossing the Mediterranean to the island of Lampedusa, near Sicily, in June 2013.

Francis demanded that Catholics and the broader global community pay attention to the dignity and humanity of migrants and called for a reawakening of people’s consciences “so that what happened would not be repeated.” Francis called the apathy to the death of migrants “globalization of indifference” to suffering.

He urged Catholics around the world to show love and mercy for the most vulnerable people in demonstrable ways. Calling it the “art of accompaniment,” he used the imagery of walking alongside the poor and taking off sandals in a sign of solidarity.

As the first pope from Latin America, Francis’ teachings on accompaniment were rooted in the Catholic liberation theology that spread throughout the region in the late 1960s and 1970s.

Liberation theology embraces putting the needs of the most vulnerable first and is grounded in biblical teachings. It prioritizes a “preferential option for the poor.”

Francis stands within a long tradition of Catholic social teaching that can be traced back to Pope Leo XIII. Leo was the first modern pope to coin the term “social doctrine,” an official Catholic teaching on how to build and maintain just and equitable economies.

Leo issued the papal document “Rerum Novarum” – “On Capital and Labor” – in May 1891 in the midst of the Industrial Revolution. Rerum Novarum emphasized the dignity of work and called for fair wages and humane working conditions.

The Catholic Church today and immigration

In more recent times, Pope Leo XIV – like his predecessor Francis and the earlier pope whose name he chose – has embraced a preferential option for the poor and an ethic of accompaniment. On Oct. 9, 2025, he issued his first exhortation, “Dilexi Te” – “I Have Loved You” – continuing Francis’ and the modern church’s focus on caring for vulnerable people.

In a section dedicated to migrants, he wrote that humans will be judged by how well they treat people who are poor, sick, imprisoned and foreign. Demonstrating love and concern for the poor, Leo emphasized, was a “hallmark of faith.”

Leo also endorsed a Nov. 12 pastoral message from the U.S. Catholic Council of Bishops urging immigration reforms that “recognize the fundamental dignity of all persons,” while maintaining national security interests, as both were possible. He urged Catholics and other “people of goodwill” to “listen carefully” to this message.

Accompaniment and people of goodwill

Accompaniment is uniquely Catholic, but the social thought it describes goes far beyond any religious denomination. From Los Angeles to Washington, D.C., everyday Catholics and non-Catholics alike have been demonstrating solidarity with the immigrants.

They are rejecting ICE’s aggressive tactics while demonstrating that they value human dignity and human rights.

Accompaniment appears to be a common language of solidarity – a way for “people of goodwill,” as Leo put it – to stand in solidarity with the most vulnerable people and refuse to accept immigration policies they see as being dehumanizing.

Baptists have helped shape debate about religious freedom for over 400 years – up to today’s 10 Commandments laws

Louisiana can proceed with a law requiring public schools to display the Ten Commandments, according to a federal court decision on Feb. 20, 2026. The U.S. Fifth Circuit Court of Appeals voted that it is too early to determine whether the requirement violates the First Amendment of the Constitution, which protects religious liberty and prohibits the government from establishing religion. The judges heard arguments in Louisiana’s law and a similar Texas one in January 2025 but have yet to rule on the latter.

One of the plaintiffs in a lawsuit filed against the Texas law is Rev. Griff Martin, a Baptist pastor. Martin has criticized the Ten Commandments mandate as not just a violation of American precepts but religious ones as well. In a press release by the American Civil Liberties Union of Texas, which is representing the plaintiffs, he stated that “the separation of church and state (is) a bedrock principle of my family’s Baptist heritage.”

Speaker of the House Mike Johnson, who represents Louisiana, is also the country’s most prominent Baptist politician – and perceives the matter differently. The Louisiana law is not an effort to establish religion, but to acknowledge the country’s “history and tradition,” he told reporters in 2024.

Baptists have long advocated for religious freedom. But as a scholar of Baptist theology and history, I know that this record is far from simple. In fact, both Martin and Johnson have ample precedent for their opinions on Baptist identity and the relationship between church and state.

Historians and political scientists often divide interpretations of the First Amendment into two broad categories: “separationism” and “accommodationism.” According to separationists, government and religion should have no formal relationship. Accommodationists, on the other hand, believe government depends on and should encourage religion in general – or Christianity, specifically.

An honest look at their history reveals that Baptists have taken various stances in this debate, reflecting their overall diversity.

Call for separation

The phrase “separation of church and state” is famously traced back to an exchange between Thomas Jefferson and a group of Baptists.

A formal portrait of a man in a gray wig, black jacket and white scarf.

After Jefferson’s election as president in 1800, the Danbury Baptist Association in Connecticut wrote a letter of congratulations. Jefferson responded, celebrating their shared beliefs in religious liberty. He cited the First Amendment, which says that “Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof.” In Jefferson’s interpretation, religion is a matter between individuals and God, and so these clauses rightly erected a wall that defended conscience from the government.

But the image of a barrier between church and state is older than Jefferson’s letter. It first appears in the writing of Roger Williams, a radical preacher who founded Rhode Island in 1636. This was the first American colony to grant religious freedom for all people. Williams also helped organize America’s first Baptist church. In one of his works, Williams explained that the “hedge or wall of Separation” protected the “Garden of the Church” from the world.

Baptist separationism goes back to the beginning of the movement. The first Baptists were a group of English exiles living in Amsterdam in 1609. The church split, and part of the community returned to Britain under the leadership of Thomas Helwys.

In 1612, Helwys boldly delivered a book to King James called “A Short Declaration of the Mystery of Iniquity.” In it, he offered the first defense of absolute religious liberty in the English language.

Helwys declared the king was mortal and not God. Therefore, a ruler “hath no power over the mortal soul of his subjects” in matters of religion. He argued for tolerance not just of different Christian sects but other religions and nonbelievers: “Let them be heretics, Turks, Jews, or whatsoever, it appertains not to the earthly power to punish them in the least measure.”

King James had Helwys thrown in prison for his impudence, where he eventually died.

Baptists who argue for strict separation of church and state have done so for several reasons. They believe that the conscience of each individual must be respected. They contend that government is not competent to judge between true and false religion. And they fear that an alliance with state power corrupts the church’s witness to the gospel.

Seeking accommodation

As much as contemporary Baptists quote Helwys, his work was forgotten for many years following his death. In the American Colonies, many people saw Williams’ Rhode Island colony as a land of dangerous anarchy.

Baptists faced legal obstacles and sometimes violent persecution in colonies with established churches, such as Massachusetts and Virginia. They became fierce advocates for religious liberty during the American Revolution and the framing of the Constitution. But even as they believed in liberty for individuals and churches, many Baptists also believed government should support Christian faith and morals.

A significant figure who illustrates accommodation was Isaac Backus, a Massachusetts pastor. Backus fervently opposed taxation to benefit the Congregationalist Church in some New England colonies. But he also felt that the state should reflect shared religious tenets. As a result, he endorsed various morality laws, religious tests for office and the government printing of Bibles.

Baptists who support accommodation – the idea that government should cooperate with religion – tend to see the United States as a Christian nation, not simply a nation with Christian citizens. Today, 63% of Americans identify as Christian.

Second, they argue that successful governance relies on the population being virtuous, and that the best guarantee of virtue is practicing Christianity.

Religious faith as a prerequisite for civic stability was a common belief in early America. George Washington expressed this view in his farewell address.

Johnson advocates a similar perspective today. In a 2022 lecture at Louisiana Christian University, the Baptist college that formerly employed him, Johnson asserted that God lies at America’s foundations, and decline has occurred because biblical morality has been abandoned. He has also declared in a social media post that “just government” depends on the fear of “eternal judgment.”

Divided by faith

Are you a good Baptist if you oppose government-mandated displays of the Ten Commandments? Or are you a good Baptist if you support them? From a historical perspective, the answer to both questions is yes.

Religious liberty and church-state separation remain contested concepts not just politically but theologically. Some Baptists support a neutral government and the full equality of religious minorities. At the other end of the spectrum, a few explicitly embrace Christian nationalism.

The historian Barry Hankins proposed that Baptists’ opinions on church and state depend on their perceptions of culture. Separationists see themselves comfortably finding their place in a pluralistic society. Accommodationists, meanwhile, worry that a secularized country will curtail the free exercise of religion.

On this issue, and many others, I believe Baptists will long remain a people divided by their shared faith.

Scorpions can pose a deadly threat to children – we’re identifying the global hotspots

Source: The Conversation – UK – By Michel Dugon, Head of the Venom System Lab, University of Galway

For people living in temperate regions of Europe, the Americas and much of Asia, scorpion stings are rarely a concern. But for millions of children growing up across the subtropical belt, a scorpion sting can have devastating consequences.

While snakebites are receiving increasing international attention and funding under the leadership of the World Health Organization, scorpionism (the medical term for illness caused by scorpion venom) remains under-reported, under-funded and under-researched. Worse still, this silent epidemic appears to be growing, fuelled by a combination of climate change, urbanisation, global trade and human encroachment into natural habitats.

In Brazil, scorpion stings have tripled over the past decade, as scorpions settle in major cities around the country. In Sudan, the construction of the Merowe Dam in 2009 and the rapid development of gold mining complexes displaced scorpion populations into nearby settlements, triggering localised epidemics.

In November 2021, torrential rains in Aswan, southern Egypt, drove thousands of deathstalker scorpions into homes and in the streets, injuring more than 450 residents and overwhelming local hospitals.

Globally, at least 1.2 million scorpion stings are recorded each year. While most victims recover fully, an estimated 3,000 people die annually as a direct result of scorpion stings, mostly children under the age of 13, typically from poor rural communities.

Global hotspots for scorpion deaths:

Scorpionism is not evenly distributed across the tropics. Most fatal cases occur in a dozen geographic hotspots including parts of Latin America, north Africa, the Levant, Iran and western India. All these areas have warm climates with seasonal extremes that favour scorpion activity, as well as poor housing, rapid urbanisation and limited access to healthcare that also contribute to the problem.

Scorpions thrive where people live and work – in cracks in walls, beneath rubble, among stored goods, in outdoor latrines and across agricultural land. But they are not aggressive animals. Most stings occur defensively when a scorpion is accidentally trapped or pressed against the skin.

Lethal scorpions

Of the roughly 2,500 known scorpion species worldwide, only 50 to 100 are considered lethal to humans. Severe envenoming – cases that requiring extensive medical attention and a hospital stay – usually involves intense local pain rapidly followed by profuse sweating, excessive salivation, vomiting and irregular heartbeat. In severe cases, fluid accumulates in the lungs, leading to respiratory failure.

Intensive care beds, ventilation support and medications that stabilise heart and lung function are essential to help young patients withstand the first 24 to 36 hours following severe envenoming.

Antivenom serum developed over a century ago has significantly helped to reduce death rates in parts of Mexico, South America and Egypt. But it is not a magic bullet.

The antivenom must be administered early, requires trained personnel and appropriate facilities, and is only effective if it matches the venom of the species responsible for the sting. It can also cause severe allergic reactions including anaphylaxis. For many vulnerable communities, its cost and limited availability remain major barriers to effective treatment.

Morocco’s scorpion hotspots

Morocco illustrates the complexity of managing scorpion stings. The country hosts more than 55 scorpion species including some of the most dangerous in the world, such as members of the genus Androctonus (“man-killer” in Greek).

After years of limited success with antivenom therapy, in the early 2000s Moroccan health authorities shifted away from antivenom to focus on using respirators and other drugs to control patients’ heart rates and maintain vital organ function while in intensive care. They also began large-scale public education campaigns.

This led to a significant drop in the death rate due to scorpion stings.

Today, Morocco records around 25,000 stings annually, resulting in 50 to 100 deaths. But some areas are much more at risk than others. The rural district of Kalaat Sraghna on the northern slopes of the Atlas Mountains, for example, represents less than 2% of Morocco’s population but accounts for roughly 20% of stings nationwide. Geographic isolation, scorpion diversity and urban expansion are all likely to be contributing factors.

In most cases, the species responsible for a sting is never identified, yet this information can be critical for diagnosis and treatment. Scorpions often look similar and typically escape immediately after stinging. Neither victims nor healthcare workers can reasonably be expected to identify them accurately.

This is where zoology and ecology intersect with public health. In a new study, our team comprising Moroccan and Irish researchers conducted field surveys of 19 scorpion species and then used machine learning (a type of artificial intelligence) to understand where else they might be located throughout Morocco.

Our model identifies the environmental conditions scorpion hotspots might share, including average or extreme seasonal temperatures, annual rainfall, vegetation type and land use. It then scans the landscape for areas with similar conditions, generating probability maps of where each species is most likely to occur.

In our study, we found that soil type was the most important variable driving the distribution of high-risk scorpions across central Morocco.

We recently presented our results at the Pasteur Institute of Morocco in Casablanca, part of the country’s public health system. Our predictive maps can help prioritise intensive care capacity, ensure medications are available locally, and strengthen emergency response in rural areas by helping doctors anticipate which species have been responsible for the stings.

Importantly, this approach can be adapted to other countries facing similar challenges. Scorpionism is still overlooked on the global health agenda. But better integration of ecology, climate science and clinical sciences offers a powerful tool to prevent deaths, especially among vulnerable children.

Rain is coming to Antarctica – here’s what will change

Rain is rare in Antarctica. Scientists doing fieldwork there dress for cold and glare, not wet weather – duvet jackets, snow trousers, goggles and sunscreen. Planes land on gravel runways which are rarely icy, since there is no precipitation to freeze. Historic huts remain well preserved in the dry air.

But this is beginning to change.

Rain is already falling more frequently on the narrow and mountainous Antarctic Peninsula, the northernmost finger of the continent pointing towards South America. Already the warmest part of Antarctica, the Peninsula is warming faster than the rest of the continent, and far faster than the global average. It provides an advanced sign of what coastal Antarctica – especially the fragile West Antarctic Ice Sheet – may experience in the coming decades.

I recently led a team of scientists looking at how the Antarctic Peninsula will change this century under three scenarios: high, medium and low greenhouse gas emissions. We found that, as the peninsula warms, precipitation will rise slightly – and will increasingly fall as rain rather than snow. As days above 0°C become more common, this rainfall will fundamentally change the peninsula.

When heat and rain arrive together

Extreme weather is already causing disruption. A heatwave in February 2020 brought temperatures of 18.6°C to the northern peninsula – T-shirt weather, for almost the first time in recorded Antarctic history – while the “ice shelf” surface alongside melted at a record pace.

Atmospheric rivers – long, thin corridors of warm, moist air that start at warmer latitudes – are playing a growing role. In February 2022, one resulted in record surface melt. Another, in July 2023, brought rainfall and temperatures of +2.7°C to the peninsula in the depths of winter. These events are happening more often, delivering rain and melt to regions where neither had been observed before.

What rain does to snow and ice

Snow does not like rain. We’ve all sadly watched snowfall melt away particularly rapidly when it rains.

On the Antarctic Peninsula, rain brings heat and melts and washes away snow, stripping glaciers of their nourishment. Meltwater can also reach the bed of the glacier, lubricating its base and making glaciers slide faster. This increases iceberg calving and the rate of glacier mass loss into the ocean.

On floating ice shelves, rain compacts the snow that has fallen on the surface, meaning water starts forming ponds. This ponded meltwater then warms, as it is less reflective than the surrounding snow and ice, and can melt downwards through the ice shelf to the ocean below, weakening the ice and causing more icebergs to break off.

This can destabilise the ice shelf. Meltwater ponding has been implicated in the collapse of the Larsen A and B ice shelves in the early 2000s.

Sea ice is vulnerable too. Rain reduces snow cover and surface reflectivity, making the ice melt faster. Loss of sea ice also weakens the natural buffers that dampen ocean waves and help prevent the ends of glaciers snapping off and becoming icebergs. It also means less habitat for algae and krill, and reduces breeding platforms for penguins and seals.

Ecosystems under stress

A rainier climate will have a series of ecological impacts.

Water can flood penguin nest sites. Penguins evolved in a polar desert and aren’t adapted for rain. Their chicks’ fluffy feathers are not waterproof, so heavy rain drenches them, sometimes leading to hypothermia and death.

Together with a warming ocean, decreased sea ice and decreased krill, this pressure will affect penguins across the continent. Iconic Antarctic species such as ice-dependent Adélie and chinstrap penguins are at risk of being replaced as more adaptable gentoo penguins expand southwards.

Rainfall also alters life on smaller scales. When it strips away snow cover, it disrupts snow algae – microscopic plants that contribute to Antarctic land ecosystems. These algae feed microbes and tiny invertebrates and can darken the snow surface, increasing solar absorption and accelerating melt.

Snow normally insulates the ground, buffering temperature swings and protecting the organisms underneath. Exposed surfaces face harsher, more variable conditions.

At the same time, warming seas may make it easier for invasive marine species such as certain mussels or crabs to colonise the area.

Challenges for scientists

Humans are also not immune to the challenges posed by a rainier Antarctic Peninsula.

With increasing geopolitical interest, it is likely that human infrastructure will increase, with potential new settlements and bases to serve emerging industries such as tourism or krill fishing.

Research infrastructure was designed for snow, not sustained rainfall. Rain freezing on airstrips renders them unusable until the ice is melted. Slush and meltwater can damage buildings, tents, instruments and vehicles. Clothing and equipment may need to be redesigned.

Some entire research sites may have to move. On nearby Alexander Island, increased surface melt has already disrupted access to long-running ecological research at Mars Oasis – continuously studied since the late 1990s – resulting in gaps in the scientific record.

Heritage at risk

Historic sites are especially vulnerable.

Antarctica contains 92 designated historic sites and monuments, the result of two centuries of exploration and research. Many of these timber huts, equipment stores and early scientific installations are clustered on the peninsula.

In a warmer and wetter climate, thawing permafrost and heavier rainfall threaten the structural integrity of these sites. Timber will deteriorate faster. Foundations will sink. These sites will need more frequent maintenance, in a part of the world where conservation work is already logistically difficult.

The Antarctic Peninsula is already undergoing rapid change. If global warming moves towards 2°C or 3°C this century, extreme weather, rainfall and surface melt will intensify. Damage to ecosystems, infrastructure, glaciers and heritage sites could be severe and potentially irreversible.

Rain, once a rarity in Antarctica, is becoming a force capable of reshaping life on the peninsula. Limiting warming to below 1.5°C won’t prevent these changes entirely. But it could slow how quickly rainfall transforms the frozen continent.

Animals’ perception of time is linked to the pace of their life – new study

Source: The Conversation – UK – By Kevin Healy, Lecturer in Macroecology, University of Galway

As you read this, the screen is probably flashing over 240 times per second, yet, as a human, you won’t notice this flickering light.

However, to a fruit fly hovering above your head, the screen would represent a strobe light fit for an Ibiza rave. This is because the way different species sample time, and the rates at which they can perceive it, varies greatly across the animal kingdom.

To us, a fast moving ball might seem like a blur but to dragonflies, pigeons and even bigclaw snapping shrimp it can be seen in great detail. But for species like snails or certain deep sea fish, like the escolar, the motion is probably too fast to register at all.

But why do animals perceive time differently?

To understand why, my colleagues and I collected published measures of time perception across the animal kingdom and analysed them. Our analysis showed this variation in time perception is largely driven by the pace of a species’s lifestyle.

Devices, such as electroretinograms, can measure time perception. The electroretinogram does this by recording the electrical activity of the retina in response to a flashing light. Gradually increasing the rate of flicker until the animal can no longer see the flashing can help scientists determine the limit of its time perception (scientists call this an organism’s maximum critical flicker fusion rate).

Our analysis showed that temporal perception has even greater variation than scientists may have realised. Our perceptual limit as humans is approximately 65 flashes per second. However, birds, such as the collared flycatcher, can see up to 138 flashes per second while tsetse flies and dragonflies can distinguish up to 300 flashes per second.

At 65 flashes per second (or Hz), humans display respectable temporal perception abilities compared to other animals. It is higher compared to many mammals, such as rats at 47 Hz, but slightly lower than dogs (84 Hz).

Our eyes seem even more respectable when compared to the slowest eyes in the animal kingdom, such as the deep sea fish, the escolar, which can only perceive 12 flashes per second or the most extreme cases of the crown-of-thorns starfish and giant African snail, both of which can only perceive 0.7 flashes per second.

But why does a dragonfly have such fast eyes while starfish are confined to a world of vision blur? One idea, called Autrum’s hypothesis, is that time perception costs a lot of energy and the evolution of such fast visual systems will only emerge in species with fast paced lifestyles.

Our analysis showed strong support for this idea, with the highest rates of temporal perception found in species which had behaviour that required fast reaction times. For example, animals that fly and predators which pursue their prey, like yellowfin tuna which can swim at over 70 kmph earning them the nickname of cheetah of the sea.

In contrast, the slowest rates of temporal perception were found in slower-moving species, such as the crown-of-thorns starfish which clock a top speed of 22 meters per hour.

We also found that in aquatic environments smaller species had faster vision. For example, while a one gram threespined stickleback fish can see at 67 Hz, a 350kg Leatherback can only see at 15 Hz. This finding supports previous studies which tested the idea that smaller, more manoeuvrable animals would also have faster temporal perceptions.

Although it is still unknown why this relationship is particularly strong in aquatic environments, it may be because water allows for more instantaneous movement.

Dogs have a slighter higher temporal perception than us.

Not all environments or lifestyles encourage the evolution of faster eyes. Our analysis also found that species in dimmer environments had much lower temporal perception abilities. For example, the giant deep sea isopod (which looks a bit like a giant woodlouse) can only see at 4Hz and the nocturnal tokay gecko can only see at 21 Hz.

This lower temporal perception is due to the need to capture every photon, light particle, available in darker environments. Similar to using slower shutter speeds with a camera, eyes with retinal cells that fire more slowly are better adapted at capturing the faintest objects. However, such adaptations to the dark come at the expense of temporal perception, and like a wobbly night time photo, are susceptible to motion blur.

So what does a second feel like to a dragonfly or to a snail? As Thomas Nagel outlined in his 1974 philosophical essay, What Is It Like to Be a Bat, we can never subjectively understand what the temporal perception of a dragonfly or snail feels like. However, by measuring the limitations of their sensory system we can grasp some sense of it.

A cup falling to the floor, a car speeding past on the street or a series of lightning strikes – for us humans, an event on the scale of a second is typically a blur, something we can just about register but not in much detail. But animals all process a different amount of visual information in a second. To us, a dragonfly may seem like Neo in the Matrix experiencing bullet time, seeing the world in slow motion.

And the extremely slow temporal perception of starfish of snails means their experience or the world is probably limited to a series of blurs.

Hence while a second may be physically the same for every organism on Earth, how you perceive it depends on how fast you live.

Hibernating bears reveal clues to fighting muscle loss – new study

Source: The Conversation – UK – By John Noone, Assistant Professor & Course Director BSc Sport and Exercise Sciences, University of Limerick

During hibernation, brown bears spend up to six months lying almost completely still, without eating, drinking or exercising. When spring arrives, they leave their dens with their muscles largely intact.

For humans, the same period of inactivity would usually mean severe muscle loss, weakness and long-term health problems. Even a few weeks in bed after surgery can reduce strength and mobility. For older adults, hospital patients and people with chronic illness, long-term immobility can permanently change quality of life. How do bears manage what humans cannot?

To explore this question, my colleagues and I studied how bears protect their muscles during hibernation. Our findings, published in Acta Physiologica, suggest that the answer lies deep inside their muscle cells, in the way they manage energy over long periods of inactivity.

Muscle cells rely on structures called mitochondria to supply the energy needed for movement and basic function. These structures convert nutrients into fuel, allowing muscles to contract, repair themselves and adapt to stress. In people who stop moving for long periods, mitochondria usually decline in both number and performance. Energy production drops. Muscles weaken. Recovery becomes harder.

Bears take a different approach. During hibernation, their muscles contain fewer mitochondria, but the ones that remain work more efficiently. Rather than allowing their energy systems to deteriorate, bears streamline them. They reduce what is unnecessary and preserve what is essential. It is similar to shutting down some power stations during low demand, while upgrading the remaining ones to run more smoothly.

Inside mitochondria, energy is generated through a series of linked chemical reactions. These reactions normally rely on several entry points and fuel sources. During hibernation, bears reorganise this system.

Our research shows that they shift towards alternative energy pathways that function well at low body temperatures. Some parts of the usual machinery are reduced, while others become more important.

At the same time, bears maintain the ability to use both fat and carbohydrates. Fat provides most of the energy during winter, but flexibility remains essential. If conditions change, their muscles can adapt quickly. This reorganisation allows bears to produce enough energy to preserve muscle tissue, even while their overall metabolism slows dramatically.

Temperature plays a central role. As bears cool during hibernation, chemical reactions slow. Instead of fighting this, their muscles adjust. The structure and function of mitochondria change in ways that suit colder conditions.

This temperature-driven control acts like a natural protective system. It limits damage, reduces waste and helps prevent the breakdown that usually follows long periods of inactivity.

To understand these changes, we studied wild brown bears in Sweden during both winter and summer.

In winter, locating hibernating bears meant tracking them to hidden dens beneath deep snow. Teams worked with wildlife experts and veterinarians to safely monitor the animals and collect small muscle samples.

In summer, the challenge was different. Active bears roam huge areas and are difficult to approach. Helicopters were used to locate them, and professionals carefully sedated the animals so that biopsies could be taken safely.

Once collected, the samples were swiftly analysed. The main technique we used measures how well mitochondria produce energy in real time and only works on fresh tissue.

Comparing winter and summer samples revealed a consistent pattern. Bears reduce the number of mitochondria during hibernation but preserve their function. Energy pathways are reorganised, fuel use remains flexible and cellular damage is limited. Together, these changes allow bears to remain strong despite months of immobility.

Connecting wildlife biology with human health

The findings help explain one of nature’s most impressive examples of physical resilience. But their importance goes far beyond wildlife biology.

In humans, muscle loss is a major problem in ageing, long hospital stays, injury recovery and chronic disease. Once muscle is lost, it is difficult to rebuild. Weakness increases the risk of falls, disability and loss of independence.

Treatments rely mainly on exercise and nutrition, which are often hard to apply when people are very ill or immobile. Bears show that another approach is possible.

By making mitochondria more efficient, reorganising energy systems, and responding to temperature, their muscles remain protected even in extreme conditions. Understanding how this happens could guide future treatments that help preserve muscle in vulnerable people.

This research also has relevance beyond medicine. Astronauts lose muscle rapidly in space, and long space missions require better ways to protect physical health in low-gravity environments.

From frozen dens in Scandinavian forests to high-tech laboratories, this work connects wildlife biology with human health and space science.

Bears do not simply sleep through winter. Their muscles follow a carefully controlled programme of energy management, conservation and protection. In doing so, they leave a clear pawprint for human biology: resilience is not about maintaining everything, but about protecting the systems that matter most.

How Tourette’s causes involuntary outbursts – and what people with the condition want you to know

Source: The Conversation – Global Perspectives – By Melissa Licari, Senior Research Fellow in Child Disability, The University of Western Australia; The Kids Research Institute

Tourette syndrome campaigner John Davidson has explained he left the British Film and Television Awards (BAFTAs) ceremony early on Monday night, aware his outbursts were causing distress.

Davidson was attending the ceremony to support the film I Swear, which tells the story of his life living with the syndrome. Tourette’s can cause involuntary movements and sounds, including words.

Davidson’s outbursts during the ceremony included a racial slur while actors Michael B. Jordan and Delroy Lindon, who are Black, were presenting an award.

In a statement, Davidson stressed the words were not intentional and did not “carry any meaning”. He said he was “deeply mortified” that people might have thought otherwise.

There are valid criticisms about how the BAFTAs and the broadcaster handled the situation and failed to properly acknowledge the hurt caused, whether or not it was intended.

But the syndrome Davidson has spent his life educating people about remains sadly misunderstood. So let’s take a look at Tourette’s and the tics it causes.

A neurological disorder

Tourette’s is a neurological disorder characterised by unintentional movements and vocalisations, known as tics.

While the exact cause of Tourette’s is not fully understood, it is likely to be complex and multifactorial.

Various genes have been linked to the condition, and we know it runs in families, so it likely has a strong genetic basis.

We also know that other environmental exposures during key periods of brain development contribute to the onset and course of the condition, such as complications during pregnancy and birth, illnesses and infections, and intense stress.

Tourette syndrome also rarely occurs in isolation, with many diagnosed with attention-deficit hyperactivity disorder (ADHD), obsessive compulsive disorder (OCD) and learning disorders.

What are tics?

Tics are thought to be caused by changes in brain circuits involved in impulse control and inhibition.

People with tics often experience uncomfortable physical sensations that build up in the body called premonitory urges. These urges are difficult and often impossible to suppress, and the only way to alleviate the urge is to tic.

It is a bit like when we experience itching on our skin or tingling in our nose, sensations we relieve by scratching or sneezing.

Tics vary between people and fluctuate in frequency, type and intensity, which can be challenging to manage.

Some tics are brief movements and sounds, such as forceful blinking, facial grimacing, head jerking, sniffing, throat clearing and grunting. These are referred to as “simple” tics and are very common, particularly in young children.

Other tics involve more elaborate patterns of movements and sounds – often involving several parts of the body.

These are “complex” tics. They include motor tics like hitting oneself, kicking or dropping to the floor, and vocal tics like repeating words or phrases. This can include socially inappropriate terms such as slurs or swearwords.

It is believed the Tourette’s brain sometimes struggles to control “forbidden” impulses. A person may experience urges to say taboo words and phrases, or make inappropriate actions, when they see or hear certain things within their environment.

How common are tics?

Tics are very common among children, with simple tics occurring in up to one in five children aged between five and six. These normally resolve in a short space of time, with many people unaware they are tics.

For one in 100 children, their tics will persist and become more severe. Having both motor and vocal tics for at least 12 months, meets the diagnostic criteria for Tourette syndrome.

While Tourette’s typically first appears in early childhood, onset can also occur during adolescence and adulthood.

For most children, tics will peak during early puberty, typically between 10–12 years of age, before reducing.

But for about one in four people with Tourette syndrome, their tics will be lifelong. Around 50,000 Australians currently live with a life-long tic disorder.

The use of obscene and socially inappropriate words and phrases, referred to as coprolalia, only occurs in about 15–20% of people with Tourette’s.

Unfortunately, coprolalia is often what gets portrayed in media and entertainment, impacting the public’s understanding of Tourette’s.

Is there a cure?

Tourette syndrome currently has no cure.

Ideally, treatment should include evidence-based behavioural interventions for tics. However these can be difficult to access, with few psychologists trained in these interventions.

Other psychological therapies aim to address the person’s stress and anxiety – which are factors known to increase tics – but not their tics.

Medications are also commonly prescribed if the tics are impacting the person, but these are not effective for everyone and often have side effects.

An exhausting and disabling condition

The frequent urge to tic disrupts attention and concentration, and the tics themselves can impact many aspects of daily living, such as dressing, eating, watching TV, and even relaxing.

Tics can also cause discomfort and injury, such as muscle soreness, cramping, whiplash, dislocations and broken bones. The research I’ve done with colleagues shows two-thirds of people sustain injuries from their tics.

I was involved in a national survey in 2025 involving more than 200 people with Tourette’s and their caregivers. They told us about the challenges they faced including:

  • long wait times for diagnosis
  • little understanding of tics and the condition from health workers and teachers
  • a lack of support and limited treatment options
  • a severe negative effect on mental health.

The social stigma, bullying, exclusion and exhaustion of living with this condition often leads to significant mental health struggles.

Our research shows around 70% of people living with Tourette’s struggle with anxiety disorders and one in three experience depression. One in four adults and one in ten children with this disorder have attempted suicide.

People with Tourette’s want to be understood and accepted

Tics are not something they are doing for attention. They increase when a person is stressed, anxious or excited, and trying to hold them in can make them worse.

Not everyone experiences coprolalia but, for those that do, the inability to inhibit taboo language can lead to public scrutiny and cause embarrassment and shame. This leads to many avoiding social situations and a life of isolation.
