Supreme Court justices’ political leanings got a lot more newspaper coverage after the 2016 death of Scalia – and reporters have been mentioning them ever since

The U.S. Supreme Court has always ruled on politically controversial issues. From elections to civil rights, from abortion to free speech, the justices frequently weigh in on the country’s most debated problems.

And because of the court’s influence over national policy, political parties and interest groups battle fiercely over who gets appointed to the high court.

The public typically finds out about the court – including its significant decisions and the politics surrounding appointments – from the news media. While elected officeholders and candidates make direct appeals to their voters, the justices and Supreme Court nominees are different – they largely rely on the news to disseminate information about the court, giving the public at least a cursory understanding.

Recently, something has changed in newspaper coverage of the Supreme Court. As scholars of judicial politics, political institutions and political behavior, we set out to understand precisely how media coverage of the court has changed over the past 40 years. Specifically, we analyzed the content of every article referencing the Supreme Court in five major newspapers from 1980 to 2023.

Of course, people get their news from a variety of sources, but we have no reason to believe the trends we uncovered in our research of traditional newspapers do not apply broadly. Research indicates that alternative media sources largely follow the lead of traditional beat reporters.

What we found: Politics has a much stronger presence in articles today than in years past, with a notable increase beginning in 2016.

When public goodwill prevailed

Not many cases have been more important in the past quarter-century or, from a partisan perspective, more contentious than Bush v. Gore – the December 2000 ruling that stopped a ballot recount, resulting in then-Texas Governor George W. Bush defeating Democratic candidate Al Gore and winning the presidential election.

Bush v. Gore is particularly interesting to us because nine unelected, life-tenured justices functionally decided an election.

Surprisingly, the court’s public support didn’t suffer, ostensibly because the court had built up a sufficient store of public goodwill.

One reason public support remained steady following Bush v. Gore might be newspaper coverage. Although the court’s decision reflected the justices’ ideologies, with the more conservative members effectively voting to end the recount and its more liberal members voting in favor of the recount, newspapers largely ignored the role of politics in the decision.

For example, the New York Times case coverage indicated the justices’ names and their votes but mentioned neither the party of the president who appointed them nor their ideological leanings. The words “Democrat,” “Republican,” “liberal” and “conservative” – what we call political frames – do not appear in the Dec. 13, 2000, story about the decision.

This epitomizes court-related newspaper articles from the 1980s to the early 2000s, when reporters treated the court as a nonpolitical institution. According to our research, court-related news articles in The New York Times, The Washington Post, Chicago Tribune, Los Angeles Times and The Wall Street Journal hardly used political frames during that time.

Instead, newspapers perpetuated a dominant belief among the public that Supreme Court decisions were based almost completely on legal principles rather than political preferences. This belief, in turn, bolstered support for the court.

Recent newspaper coverage reveals a starkly different pattern.

A contemporary political court

It would be nearly impossible to read contemporary articles about the Supreme Court without getting the impression that it is just as political as Congress and the presidency.

Analyzing our data from 1980 to 2023, the average number of political frames per article tripled. To be sure, politics has always played a role in the court’s decisions. Now, newspapers are making that clear. The question is when this change occurred.

Across the five major newspapers, reporting about the court has gradually become more political over time. That isn’t surprising: America has been gradually polarizing since the 1980s as well, and the changes in news media coverage reflect that polarization.

Take February of 2016, when Justice Antonin Scalia unexpectedly died. Of course, justices have died while serving on the court before. But Scalia was a conservative icon, and his death could have swung the court to the center or the left.

How the politics of naming his successor played out after Scalia’s death was unprecedented.

President Barack Obama’s nomination effort to put Merrick Garland on the court were stonewalled. The Senate majority leader, Republican Mitch McConnell of Kentucky, said the Senate would not consider any nomination until after the presidential election, nine months from Scalia’s death.

Republican candidate Donald Trump, seeing an opening, promised to fill the vacancy with a conservative justice who would overturn Roe v. Wade. The court and the 2016 election became inseparable.

Scalia vacancy changed everything

February 2016 brought about an abrupt and lasting change in newspaper coverage. The day before Scalia’s death, a typical article referencing the court used 3.22 political frames.

The day after, 10.48.

We see an uptick in political frames if we consider annual changes as well. In 2015, newspapers averaged 3.50 political frames per article about the Supreme Court. Then, in 2016, 5.30.

Using a variety of statistical methods to identify enduring framing shifts, we consistently find February 2016 as the moment newspapers shifted to higher levels of political framing of the court. We find the number of political frames in newspapers remained elevated through 2023.

How stories frame something shapes how people think about it.

If an article frames a court decision as “originalist” – an analytical approach that says constitutional texts should be interpreted as they were understood at the time they became law – then readers might think of the court as legalistic.

But if the newspaper were to frame the decision as “conservative,” then readers might think of the court as ideological.

We found in our study that when people read an article about a court decision using political frames, court approval declines. That’s because most people desire a legal court rather than a political one. No wonder polls today find the court with precariously low public support.

We do not necessarily hold journalists responsible for the court’s dramatic decline in public support. The bigger issue may be the court rather than reporters. If the court acts politically, and the justices behave ideologically, then reporters are doing their job: writing accurate stories.

That poses yet another problem. Before Trump’s three court appointments, the bench was known for its relative balance. Sometimes decisions were liberal; other times, conservative.

In June 2013, the court provided protections to same-sex marriages. Two days earlier, the court struck down part of the Voting Rights Act. A liberal win, a conservative win – that’s what we might expect from a legal institution.

Today the court is different. For most salient issues, the court supports conservative policies.

Given, first, the media’s willingness to emphasize the court’s politics, and second, the justices’ ideologically consistent decisions across critical issues, it is unlikely that the news media retreats from political framing anytime soon.

If that’s the case, the court may need to adjust to its low public approval.

College ‘general education’ requirements help prepare students for citizenship − but critics say it’s learning time taken away from useful studies

What do Americans think of when they hear the words “general education”?

By definition, general education covers introductory college courses in arts and humanities, social sciences, and science and mathematics. It has different names, including core curriculum or distribution requirements, depending on the college or university.

It is also sometimes called liberal education, including by the American Association of Colleges and Universities, which describes it as providing “a sense of social responsibility, as well as strong and transferable intellectual and practical skills.”

The liberal label can be fodder for conservative groups who argue that today’s general education is part of an indoctrination into higher education’s purported left-leaning belief systems. Some other conservatives support general education as a concept but want more emphasis on so-called traditional values and less on cross-cultural understanding. These initiatives position general education and college as a space for ideological battles.

As a scholar of historical connections between literacy and social class, I know that general education was designed to provide opportunity for all students without regard for their political preferences.

An education for all

Eighty years ago, a group of Harvard University faculty created what many colleges and universities still follow as a template for general education. This plan was outlined in the book “General Education in a Free Society.”

Harvard’s plan was meant for all students, including veterans studying under the GI Bill, and others we today refer to as first generation, where neither parent had a college degree.

General education made college more accessible to students who were not becoming doctors or lawyers but who also wanted careers outside the vocational trades. It helped make college a place for educating all citizens, not just students of socioeconomic privilege.

Expanding access to higher education was central to the 1947 special report Higher Education for American Democracy, commissioned by President Harry Truman. The goal was to provide a foundational education for all, especially in math and science. But the report, commonly known as the Truman Commission Report, also included disciplines that help students understand the world – such as writing and communication, literature, psychology and history.

The purposes of general education are central to two competing views of college today, views that I also hear expressed by students and parents I’ve met in my 28 years as a professor.

One view of college is of an on-campus experience steeped in the liberal arts that holistically prepares students to live in a functioning democracy. These benefits are seen as worth the time and costs.

The other view is of college as a sum of career-focused credentials that can begin and end anywhere, not specific to one college campus. These benefits are completely financial, to be gained via the cheapest, quickest means.

Both of these views are informed by national perspectives that further divide citizens on higher education as a whole, such as Vice President JD Vance’s 2021 statement that “there was a wisdom in what Richard Nixon said approximately 40, 50 years ago. He said, and I quote, ‘The professors are the enemy.’”

Both these groups of Americans, however, hope that obtaining a college degree will pay off for graduates who find employment and reach a standard of living better than their parents’ generation.

For the first group, general education is critical to developing the whole student for jobs and life. For the latter, it is an expensive obstacle to it.

Not surprisingly, these views on education and college often correspond to political party identification and whether a person attended college themselves.

A July 2023 Lumina Foundation and Gallup Poll showed that only 36% of Americans have a “great deal” of confidence in higher education, with significant partisan differences between the 20% of Republicans who have this confidence, the 56% of Democrats and the 35% of independents who have it. There are also measurable differences between those who have earned a postgraduate degree and those who have not.

Questioning value

As college costs continue to rise in 2025, families are struggling – even taking on payment plans for everyday purchases, also known as phantom debt – to make ends meet.

General education represents about a third of the requirements of a bachelor’s degree and most of an associate degree.

For those who see college as a waste of money, general education courses are a calculable loss on future income. In the past two decades, this – and the increasingly competitive admissions process for college – has contributed to a tenfold increase in low-income students who take Advanced Placement courses and a 50% increase since 2021 in the number of students in dual-credit coursework. Both programs allow students to complete general education-equivalent courses for free while still in high school.

Complete College America, a nonprofit advocacy group that works with states to increase college completion rates, supports these moves by students and parents, classifying general education under “gateway courses” to be completed “as soon as possible.”

Other groups promote stackable units of credit toward college degrees. This push to complete general education requirements before entering college is gaining momentum, despite studies that show Advanced Placement classes, and exams, favor and benefit mostly white, middle- to upper-class students because these students tend to have more time and resources to devote to AP coursework and also take multiple exams in order to earn college credit.

Understanding the world

While arguments for streamlining college and its costs are evergreen, foundational lessons taught across fields of study are as relevant in 2025 as they were in 1945. The U.S. faces threats to its democracy, is navigating rapid advances in technology, and is adapting to population shifts that will change how its residents live and work.

General education gives students broad foundational knowledge that can be used in a variety of careers. By design, it teaches an understanding of the world outside one’s own and how to live in it – a core requirement for a functioning democracy.

Data can show if government programs work or not, but the Trump administration is suppressing the necessary information

Source: The Conversation – USA (2) – By Sarah James, Assistant Professor of Political Science, Gonzaga University

Do government programs work? It’s impossible to find out with no data. Andranik Hakobyan/iStock via Getty Images Plus

The U.S. has the highest rate of maternal mortality among developed nations. Since 1987, the Centers for Disease Control and Prevention has administered the Pregnancy Risk Assessment Monitoring System to better understand when, where and why maternal deaths occur.

In April 2025, the Trump administration put the department in charge of collecting and tracking this data on leave.

It’s just one example of how the administration is deleting and disrupting American data of all kinds.

The White House is also collecting less information about everything from how many Americans have health insurance to the number of students enrolled in public schools, and making government-curated data of all kinds off-limits to the public. President Donald Trump is also trying to get rid of entire agencies, like the Department of Education, that are responsible for collecting important data tied to poverty and inequality.

His administration has also begun deleting websites and respositories that share government data with the public.

Why data is essential for the safety net

I study the role that data plays in political decision-making, including when and how government officials decide to collect it. Through years of research, I’ve found that good data is essential – not just for politicians, but for journalists, advocates and voters. Without it, it’s much harder to figure out when a policy is failing, and even more difficult to help people who aren’t politically well connected.

Since Trump was sworn in for a second time, I have been keeping an eye on the disruption, removal and defunding of data on safety net programs such as food assistance and services for people with disabilities.

I believe that disrupting data collection will make it harder to figure out who qualifies for these programs, or what happens when people lose their benefits. I also think that all this missing data will make it harder for supporters of safety net programs to rebuild them in the future.

Why the government collects this data

There’s no way to find out whether policies and programs are working without credible data collected over a long period of time.

For example, without a system to accurately measure how many people need help putting food on their tables, it’s hard to figure out how much the country should spend on the Supplemental Nutrition Assistant Program, formerly known as food stamps, the federal supplemental nutrition program for women, infants and children, known as WIC, and related programs. Data on Medicaid eligibility and enrollment before and after the passage of the Affordable Care Act in 2010 offers another example. National data showed that millions of Americans gained health insurance coverage after the ACA was rolled out.

Many institutions and organizations, such as universities, news organizations, think tanks, and nonprofits focused on particular issues like poverty and inequality or housing, collect data on the impact of safety net policies on low-income Americans.

No doubt these nongovernmental data collection efforts will continue, and maybe even increase. However, it’s highly unlikely that these independent efforts can replace any of the government’s data collection programs – let alone all of them.

The government, because it takes the lead in implementing official policies, is in a unique position to collect and store sensitive data collected over long periods of time. That’s why the disappearance of thousands of official websites can have very long-term consequences.

What makes Trump’s approach stand out

The Trump administration’s pausing, defunding and suppressing of government data marks a big departure from his predecessors.

As early as the 1930s, U.S. social scientists and local policymakers realized the potential for data to show which policies were working and which were a waste of money. Since then, policymakers across the political spectrum have grown increasingly interested in using data to make government work better.

This focus on data grew starting in 2001, when President George W. Bush made holding government accountable to measurable outcomes a top priority.

He saw data as a powerful tool for reducing waste and assessing policy outcomes. His signature education reform, the No Child Left Behind Act, radically expanded the collection and reporting of student achievement data at K-12 public schools.

How this contrasts with the Obama and Biden administrations

Presidents Barack Obama and Joe Biden emphasized the importance of data for evaluating the impact of their policies on low-income people, who have historically had little political clout.

Obama initiated a working group to identify ways to collect, analyze and incorporate more useful data into safety net policies. Biden implemented several of the group’s suggestions.

For example, he insisted on the collection of demographic data and its analysis when assessing the impacts of new safety net policies. This approach shaped how his administration handled changes in home loan practices, the expansion of broadband access and the establishment of outreach programs for enrolling people in Medicaid and Medicare.

Why rebuilding will be hard

It’s harder to make a case for safety net programs when you don’t have relevant data. For example, programs that help low-income people see a doctor, get fresh food and find housing can be more cost-effective than simply having them continue to live in poverty.

Blocking data collection may also make restoring government funding after a program gets cut or shut down even more challenging. That’s because it will be more challenging for people who in the past benefited from these programs to persuade their fellow taxpayers that there is a need for investing in a expanding program or creating a new one.

Without enough data, even well-intended policies in the future may worsen the very problems they’re meant to fix, long after the Trump administration has concluded.

Children living near oil and gas wells face higher risk of rare leukemia, studies show

Acute lymphocytic leukemia is one of the most commonly diagnosed cancers in children, although it is rare. It begins in the bone marrow and rapidly progresses.

Long-term survival rates exceed 90%, but many survivors face lifelong health challenges. Those include heart conditions, mental health struggles and a greater chance of developing a second cancer.

Overall cancer rates in the U.S. have declined since 2002, but childhood acute lymphocytic leukemia rates continue to rise. This trend underscores the need for prevention rather than focusing only on treatment for this disease.

A growing body of literature suggests exposure to the types of chemicals emitted from oil and natural gas wells increases the risk of developing childhood acute lymphocytic leukemia.

We are environmental epidemiologists focused on understanding the health implications of living near oil and natural gas development operations in Colorado and Pennsylvania. Both states experienced a rapid increase in oil and natural gas development in residential areas beginning in the early 21st century. We’ve studied this issue in these states, using different datasets and some different approaches.

2 studies, similar findings

Both of our studies used a case-control design. This design compares children with cancer, known as cases, with children without cancer, known as controls. We used data from statewide birth and cancer registries.

We also used specialized mapping techniques to estimate exposure to oil and natural gas development during sensitive time windows, such as pregnancy or early childhood.

The Colorado study looked at children born between 1992 and 2019. The study included 451 children diagnosed with leukemia and 2,706 children with no cancer diagnosis. It considered how many oil and natural gas wells were near a child’s home and how intense the activity was at each well. Intensity of activity included the volume of oil and gas production and phase of well production.

The Colorado study found that children ages 2-9 living in areas with the highest density and intensity wells within eight miles (13 kilometers) of their home were at least two times more likely to be diagnosed with acute lymphocytic leukemia. Children with wells within three miles (five kilometers), of their home bore the greatest risk.

The Pennsylvania study looked at 405 children diagnosed with leukemia between 2009 and 2017 and 2,080 children without any cancer diagnosis. This study found that children living within 1.2 miles (two kilometers) of oil and natural gas wells at birth were two to three times more likely to be diagnosed with acute lymphocytic leukemia between ages 2 to 7 than those who lived farther than 1.2 miles away.

The risk of developing leukemia was more pronounced in children who were exposed during their mother’s pregnancy.

The results of our two studies are also supported by a previous study in Colorado published in 2017. That study found children diagnosed with acute lymphocytic leukemia were four times more likely to live in areas with a high density of oil and natural gas wells than children diagnosed with other cancers.

Policy implications

To extract oil and natural gas from underground reserves, heavy drilling equipment injects water and chemicals into the earth under high pressure. Petroleum and contaminated wastewater are returned to the surface. It is well established that these activities can emit cancer-causing chemicals. Those include benzene, as well as other pollutants, to the air and water.

The U.S. is the world’s largest producer of oil and natural gas. There are almost 1 million producing wells across the country, and many of these are located in or near residential areas. This puts millions of children at increased risk of exposure to cancer-causing chemicals.

In the U.S., oil and natural gas development is generally regulated at the state level. Policies aimed at protecting public health include establishing minimum distances between a new well and existing homes, known as a setback distance. These policies also include requirements for emission control technologies on new and existing wells and restrictions on the construction of new wells.

Setbacks offer a powerful solution to reduce noise, odors and other hazards experienced by communities near oil and gas wells. However, it is challenging to establish a universal setback that optimally addresses all hazards. That’s because noise, air pollutants and water contaminants dissipate at different rates depending on location and other factors.

In addition, setbacks focus exclusively on where to place oil and natural gas wells but do not impose any restrictions on releases of air pollutants or greenhouse gases. Therefore, they do not address regional air quality issues or mitigate climate change.

Furthermore, current U.S. setback distances range from just 200 feet to 3,200 feet. Our results indicate that even the largest setback of 3,200 feet (one kilometer) is not sufficient to protect children from an increased leukemia risk.

Our results support a more comprehensive policy approach that considers both larger setback distances and mandatory monitoring and control of hazardous emissions on both new and existing wells.

Future research

More research is needed in other states, such as Texas and California, that have oil and natural gas development in residential areas, as well as on other pediatric cancers.

One such cancer is acute myeloid leukemia. This is another type of leukemia that starts in bone marrow and rapidly progresses. This cancer has exhibited a strong link to benzene exposure in adult workers in several industries, including the petroleum industry. Researchers have also documented a moderate cancer link for children exposed to vehicular benzene.

It remains unclear whether benzene is the culprit or if another agent or combination of hazards is an underlying cause of acute myeloid leukemia.

Even though questions remain, we believe the existing evidence coupled with the seriousness of childhood acute lymphocytic leukemia supports enacting further protective measures. We also believe policymakers should consider the cumulative effects from wells, other pollution sources and socioeconomic stressors on children and communities.

When grief involves trauma − a social worker explains how to support survivors of the recent floods and other devastating losses

The July 4, 2025, floods in Kerr County, Texas, swept away children and entire families, leaving horror in their wake. Days later, flash floods struck Ruidoso, New Mexico, killing three people, including two young children.

These are not just devastating losses. When death is sudden, violent, or when a body is never recovered, grief gets tangled up with trauma.

In these situations, people don’t only grieve the death. They struggle with the terror of how it happened, the unanswered questions and the shock etched into their bodies.

I’m a social work professor, grief researcher and the founder of The Young Widowhood Project, a research initiative aimed at expanding scholarship and public understanding of premature spousal loss.

I was widowed when I was 36. In July 2020, my husband, Brent, went missing after testing a small, flat-bottomed fishing boat called a Jon boat. His body was recovered two days later, but I never saw his remains.

Both my personal loss and professional work have shown me how trauma changes the grieving process and what kind of support actually helps.

To understand how trauma can complicate grief, it’s important to first understand how people typically respond to loss.

Grief isn’t a set of stages

Many people still think of grief through the lens of psychiatrist Dr. Elisabeth Kübler-Ross’ five stages of grief, popularized in the early 1970s: denial, anger, bargaining, depression and acceptance.

But in fact, this model was originally designed for people facing their own deaths, not for mourners. In the absence of accessible grief research in the 1960s, it became a leading framework for understanding the grieving process – even though it wasn’t meant for that.

Despite this misapplication, the stages model has shaped cultural expectations: namely, that grief ends once people reach the “acceptance” stage. But research doesn’t support this idea. Trying to force grief into this model can cause real harm, leaving mourners feeling they’re grieving “wrong.”

In reality, mourning is often lifelong. Most people go through an acute period of overwhelming pain right after the loss. This is usually followed by integrated grief, where the pain softens but the loss is still part of everyday life, returning in waves.

Although grief is unique to each person and relationship, researchers have found that mourners often strive to a) make sense of the death; b) adjust to a world without their loved one; c) form an ongoing connection with their deceased loved one in new ways; and d) figure out who they are without their loved one.

It’s difficult and at times disorienting work, but most people find ways to carry their grief and keep living.

When grief and trauma collide

However, some losses carry an extra layer of pain, confusion and trauma.

Sudden, unexpected, accidental, violent or deeply tragic deaths – like those experienced during the recent floods – can lead to what researchers call traumatic bereavement: grief that is disrupted by the traumatic nature of the death.

People experiencing traumatic bereavement often endure a longer and more intense acute grief period. They may be haunted by disturbing images, nightmares or relentless thoughts about how their loved one died or suffered. Many wrestle with dread, spiritual disorientation and a shattered sense of safety in the world.

Some of these deaths are also considered “ambiguous” – unclear or unconfirmed loss – such as when a body is never recovered or is too damaged to view. Without physical confirmation, mourners often feel stuck in disbelief and helplessness.

This was true in my case. Not seeing my husband’s body left a part of me suspended between knowing and not knowing. I knew he had died but couldn’t fully believe it, no matter how much I lived with the reality of his absence. For a long time, I caught myself repeating these words every morning: “Brent is dead. Brent is dead.”

In many cases, these reactions aren’t short term. Many people affected by traumatic loss remain overwhelmed and sometimes physically and emotionally impaired for years. Symptoms may taper over time, but they rarely disappear entirely.

Supporting mourners

Traumatic bereavement can feel unbearable. Many mourners struggle with intense, long-lasting reactions that can leave them feeling helpless, altered or even unrecognizable to themselves. They may appear withdrawn, forgetful or emotionally drained because their systems are overwhelmed. Coping can look messy or self-destructive, but these are often survival strategies, not conscious choices. I’ve also seen how those same struggles become more survivable when mourners don’t have to carry them alone. If you’re supporting someone through traumatic loss, here are three ways to help.

  • Make space for the horror. Listen without flinching. Acknowledge the full weight of what happened and how terrifying and unjust the loss was. This means saying things like, “This should never have happened,” or “What you went through is beyond words.” It means staying present when the mourner speaks about what haunts them. Let them know they don’t have to carry this alone. You may feel the urge to say something hopeful such as, “At least the body was recovered,” but there is no silver lining in these cases. Instead, say: “There’s nothing I can say to fix this, but I’m not going anywhere.”

  • Help them find others who can understand. Trauma can be isolating. Mourners often feel uniquely overwhelmed or confused. Support groups, peer companions and therapists trained in treating grief and trauma can offer the kind of recognition and validation that even the most devoted friend may not be able to provide.

  • Take care of yourself, too. Being present for someone in deep grief takes energy, especially if you were personally affected by the loss. Stay connected to replenishing people, practices and routines. If you don’t, you may begin to experience trauma, too. Taking care of yourself will help you remain grounded so that you can show up.

I believe supporting someone through traumatic bereavement is one of the most meaningful things you can do. You don’t need perfect words or a plan. What sustains them won’t be advice or solutions, but your simple, powerful act of staying.

Babies born with DNA from three people hailed as breakthrough – but questions remain

Source: The Conversation – UK – By Cathy Herbrand, Professor of Medical and Family Sociology, De Montfort University

Ten years after the UK became the first country to legalise mitochondrial donation, the first results from the use of these high-profile reproductive technologies – designed to prevent passing on genetic disorders – have finally been published.

So far, eight children have been born, all reportedly healthy, thanks to the long-term efforts of scientists and doctors in Newcastle, England. Should this be a cause for excitement, disappointment or concern? Perhaps, I would suggest, it could be a bit of all three.

The New England Journal of Medicine has published two papers on a groundbreaking fertility treatment that could prevent devastating inherited diseases. The technique, called mitochondrial donation, was used to help 22 women who carry faulty genes that would otherwise pass serious genetic disorders – such as Leigh syndrome – to their children. These disorders affect the body’s ability to produce energy at the cellular level and can cause severe disability or death in babies.

The technique, developed by the Newcastle team, involves creating an embryo using DNA from three people: nuclear DNA from the intended mother and father, and healthy mitochondrial DNA from a donor egg. During the parliamentary debates leading up to The Human Fertilisation and Embryology (Mitochondrial Donation) Regulations in 2015, there were concerns about the effectiveness of the procedure and its potential side effects.

The announcement that this technology has led to the birth of eight apparently healthy children therefore marks a major scientific achievement for the UK, which has been widely praised by numerous scientists and patient support groups. However, these results should not detract from some important questions they also raise.

First, why has it taken so long for any updates on the application of this technology, including its outcomes and its limitations, to be made public? Especially given the significant public financial investment made into its development.

In a country positioning itself as a leader in the governance and practice of reproductive and genomic medicine, transparency should be a central principle. Transparency not only supports the progress of other research teams but also keeps the public and patients well informed.

Second, what is the significance of these results? While eight babies were born using this technology, this figure contrasts starkly with the predicted number of 150 babies per year likely to be born using the technique.

The Human Fertilisation and Embryology Authority, the UK regulator in this area, has approved 32 applications since 2017 when the Newcastle team obtained its licence, but the technique was used with only 22 of them, resulting in eight babies. Does this constitute sufficiently robust data to prove the effectiveness of the technology and was it worth the considerable efforts and investments over almost two decades of campaigning, debate and research?

As I wrote when this law was passed, officials should have been more realistic about how many people this treatment could actually help. By overestimating the number of patients who might benefit, they risked giving false hope to families who wouldn’t be eligible for the procedure.

The safety question

Third, is it safe enough? In two of the eight cases, the babies showed higher levels of maternal mitochondrial DNA, meaning the risk of developing a mitochondrial disorder cannot be ruled out. This potential for a “reversal” – where the faulty mitochondria reassert themselves – was also highlighted in a recent study conducted in Greece involving patients who used the technique to treat infertility problems.

As a result, the technology is no longer framed by the Newcastle team as a way to prevent the transmission of mitochondrial disorders, but rather to reduce the risk. But is the risk reduction enough to justify offering the technique to more patients? And what will the risk of reassertion mean for the children born through it and their parents, who may live with the continuing uncertainty that the condition could emerge later in life?

As some experts have suggested, it may be worth testing this technology on women who have fertility problems but don’t carry mitochondrial diseases. This would help doctors better understand the risks of the faulty mitochondria coming back, before using the technique only on women who could pass these serious genetic conditions to their children.

This leads to a fourth question. What has been the patient experience with this technology? It would be valuable to know how many people applied for mitochondrial donation, why some were not approved, and, among those 32 approved cases, why only 22 proceeded with treatment.

It also raises important questions about how patients who were either unable to access the technology, or for whom it was ultimately unsuccessful feel, particularly after investing significant time, effort and hope in the process. How do they come to terms with not having the healthy biological child they had been offered?

This is not to say we shouldn’t celebrate these births and what they represent for the UK in terms of scientific achievement. The birth of eight healthy children represents a genuine scientific breakthrough that families affected by mitochondrial diseases have waited decades to see. However, some important questions remain unanswered, and more evidence is needed and it should be communicated in a timely manner to make conclusions about the long-term use of the technology.

Breakthroughs come with responsibilities. If the UK wants to maintain its position as a leader in reproductive medicine, it must be more transparent about both the successes and limitations of this technology. The families still waiting to have the procedure – and those who may never receive it – deserve nothing less than complete honesty about what this treatment can and cannot deliver.

East African countries and open borders: great strides, but still a long way to go

Source: The Conversation – Africa – By Alan Hirsch, Senior Research Fellow New South Institute, Emeritus Professor at The Nelson Mandela School of Public Governance, University of Cape Town

It’s not uncommon to find a Ugandan taxi driver in Rwanda’s capital, Kigali, just as one regularly meets Zimbabwean Uber drivers in South Africa. But there is a big difference. A Ugandan working in Rwanda most likely has a secure legal right to be there, whereas Zimbabweans working in South Africa are often uncertain of their current or future legality.

East Africa has made greater strides towards the free flow of people crossing borders and seeking work than most of Africa. Only the Economic Community of West African States (Ecowas) is in the same league.

While the African Union’s Free Movement of Persons protocol has faltered at a continental level, some of the regional economic communities have made progress. The Southern African Development Community (SADC) allows visa-free travel across almost all its borders.

Ecowas and the East African Community (EAC) have driven ambitiously towards regional common markets including the freeing up of job-seeking, residential settlement and business development across the borders of member states.

The New South Institute, a think-tank focused on governance reforms in the global south, is nearing the end of a research programme on migration governance reform in Africa. Our new report is on East Africa.

We have found that unlike much of the global north, the African continent is moving towards more open borders for people. In some of the global south the promise of economic growth outweighs political fears. Yet progress is slow, and not coordinated. Mostly migration reform happens in regions and between neighbours.

The progress in the East African Community is particularly notable compared with other African regional communities. We identify a number of reasons for this, including strong leadership and co-operation between state and non-state actors.

The commitment to free movement

The East African Community adopted its Common Market Protocol in 2010. The bloc is made up of Tanzania, Uganda, Kenya, Rwanda, Burundi, South Sudan, the DRC and Somalia.

The regional body’s common market pact includes the movement of goods, services, capital and people. It gives people the right – on paper at least – to find employment across borders, the right to reside and the right to establish a business. There is also a commitment to the harmonisation and mutual recognition of academic and professional qualifications and labour policies to ease mobility.

Even before the common market protocol, the regional bloc began to establish one-stop border posts on many of its internal borders to facilitate the flow of goods and people. Though they don’t all operate the same way or equally well, they have been successful at easing movement.

Uneven outcomes

The common market’s impact on the movement of people has been uneven within the region. Most integrated are Uganda, Kenya and Rwanda, which allow the cross-border movement of citizens with standardised identity documents – they do not need passports.

It is also relatively easy to get jobs across these borders.

Tanzania and Burundi are close to the inner circle but still require passports, though no visas. The three states which joined more recently, South Sudan, the DRC and Somalia, are all fragile states with governance systems that do not always meet the standards needed for acceptance into all the privileges of the regional bloc.

In practice there is differential treatment. Generally, it is more difficult for citizens of the three latecomers to get regular access and jobs in their regional partners.

Another limitation when it comes to the mobility of people is that little progress has been made in the formal harmonisation of education, health and social welfare systems between member states. This inhibits job seeking across borders.

In addition, national labour laws, which tend to require permits for foreigners, still apply to varying degrees in the region. Some countries are more permissive. For example, Kenya, Uganda and Rwanda have a reciprocal no-fee work permit agreement.

Another shortcoming has been that the outcomes of court processes in enforcing the freedom of movement have been disappointing. This is so even though the regional bloc has an active East African Court of Justice. Its legal mandate includes the enforcement of the bloc’s treaty and its protocols.

In some cases the court has found that national actions inhibiting the movement of persons were trumped by the regional protocol. It has instructed the errant governments to comply. But its ability to enforce the decisions is minimal.

Reasons for success

Leadership has been important. The fact that the strongest economy in the region, Kenya, has been part of the leading echelon is significant.

Rwanda and Uganda have led by example too. Rwanda was one of the first countries on the continent to offer visa-free entry to all other African countries. For its part, Uganda is widely admired for its refugee inclusion programmes.

Another factor outlined in our report has been the opportunity for collaboration fostered by relationships between formal institutions, such as governments, and non-state actors such as the International Organisation for Migration. Interactions between these various players have created opportunities for officials and policymakers from states of the region to meet, discuss issues of concern, and develop relationships of trust and understanding.

Another non-state donor-funded actor, TradeMark Africa, which was established in 2010 to support in the implementation of the common market in east Africa, provided considerable support. For example it supported the implementation of the regional One-Stop Border Post programme..

Way forward

Based on our report we identified changes that could make a positive difference.

Firstly, the development of reliable, harmonised systems in the region to collect and manage data on population mobility and employment. This would build confidence that policy was being made on the basis of reliable information.

Secondly, reducing friction in cross-border monetary transactions, including migrants’ remittances. This would make it easier for migrants to send some of their income to their countries of origin.

Thirdly, improvements to population registers, identity documents, passports and cross-border migration management systems. Improvements would build mutual trust in the integrity of systems and pave the way for further commitments to lowering migration barriers.

Fourth, cooperation on cross-border access to social services such as health and education. This is one of the most important intermediate steps towards freeing up mobility for the citizens of the region.

Fifth, reconsidering some of the amendments made to weaken the East African Court of Justice in 2007. This would strengthen the de jure powers of the court, adding considerably to the entrenchment of cross-border rights in the region.

Ultimately, the key constraint in the region is political and security instability, which holds back social and economic development. Nevertheless, incremental progress on mobility is possible despite issues in the fragile states, even though it may result in asymmetric progress within the East African Community.

Accord de paix RDC-Rwanda: les 4 éléments essentiels pour un processus de paix durable

Source: The Conversation – in French – By Philipp Kastner, Senior Lecturer in International Law, The University of Western Australia

Les gouvernements de la République démocratique du Congo (RDC) et du Rwanda ont conclu un accord de paix en juin 2025, visant à mettre fin à une guerre qui dure depuis des décennies dans l’est de la RDC. Les Nations unies ont salué cet accord comme « une étape importante vers l’apaisement, la paix et la stabilité » dans la région.

J’ai analysé plusieurs négociations et accords de paix différents. Il est important de distinguer ce qui est nécessaire pour amener les parties belligérantes à la table des négociations et ce qui est convenu à la fin des négociations. Dans cet article, j’explique dans quelle mesure l’accord entre la RDC et le Rwanda réunit les quatre éléments essentiels à sa durabilité.

Avant tout, deux observations d’ordre général sur les accords de paix et un point plus spécifique relatif à une complication particulière dans le cas de l’accord RDC-Rwanda.

Premièrement, un seul accord suffit rarement à résoudre un conflit complexe. La plupart des accords font partie d’une série d’accords, parfois entre différents acteurs. Ils font souvent référence à des accords conclus précédemment et seront cités dans les accords ultérieurs.

Deuxièmement, la paix est un processus qui nécessite un engagement large et soutenu. Il est essentiel que d’autres acteurs, tels que les groupes armés, soient impliqués dans le processus. Les acteurs de la société civile doivent également être impliqués. Plus les points de vue sont représentés dans les négociations, plus l’accord sera légitime et efficace.

Mais dans le cas de l’accord RDC–Rwanda, un élément complique la situation : le rôle des États-Unis. Washington ne semble pas avoir agi comme un médiateur neutre. Au contraire, les États-Unis semblent poursuivre leurs propres intérêts économiques. Cela n’est pas bon signe pour la suite.

Il n’existe pas de recette miracle pour un accord de paix efficace, mais les recherches montrent que quatre éléments sont importants : un engagement sérieux des parties, une langage clair et précis, un calendrier clair et des dispositions de mise en œuvre solides.

Les fondements d’un accord efficace

Tout d’abord, les parties doivent prendre l’accord au sérieux et être en mesure de s’engager à en respecter les termes. Il ne doit pas servir de prétexte pour gagner du temps, se réarmer ou poursuivre les combats. Une paix durable ne peut pas reposer uniquement sur des décisions prises au sommet de l’État. Les accords qui sont le fruit de processus plus inclusifs, avec la participation et le soutien des communautés concernées, réussissent mieux en général.

Deuxièmement, l’accord doit traiter les questions qu’il vise à résoudre, et ses dispositions doivent être rédigées avec soin et sans ambiguïté. Lorsque les accords sont vagues ou passent sous silence des aspects essentiels, ils sont souvent de courte durée. Les expériences passées peuvent guider les négociateurs et les médiateurs de paix dans le processus de rédaction. Les bases de données sur les accords de paix établies par les Nations unies et les institutions universitaires constituent un outil utile à cet égard.

Troisièmement, il est essentiel de fixer des délais clairs et réalistes. Ceux-ci peuvent concerner le retrait des forces armées de territoires spécifiques, le retour des réfugiés et des personnes déplacées à l’intérieur du pays, et la mise en place de mécanismes prévoyant des réparations ou d’autres formes de justice transitionnelle.

Quatrièmement, un accord doit inclure des dispositions relatives à sa mise en œuvre. Un soutien extérieur est généralement utile à cet égard. Des États tiers ou des organisations internationales, telles que les Nations unies et l’Union africaine, peuvent être chargés de superviser cette phase. Ils peuvent également fournir des garanties de sécurité, voire déployer une opération de maintien de la paix. Il est essentiel que ces acteurs s’engagent dans le processus et ne poursuivent pas leurs propres intérêts.

Pour bien évaluer ce qu’on peut attendre d’un accord de paix en particulier, il faut aussi garder à l’esprit qu’il existe plusieurs types d’accords. Certains sont des arrangements préparatoires ou des cessez-le-feu. D’autres sont plus complets et visent à régler le conflit dans sa globalité ou à organiser la mise en oeuvre. Un simple cessez-le-feu entre quelques acteurs ne suffit généralement pas à résoudre un conflit en profondeur.

Pour savoir ce que l’on peut attendre de manière réaliste d’un accord de paix spécifique, il est important de comprendre que ces accords peuvent prendre des formes très différentes. Celles-ci vont des accords préliminaires et des cessez-le-feu aux accords de paix globaux et aux accords de mise en œuvre.

Un simple cessez-le-feu, signé par quelques parties seulement, ne permet généralement pas de régler un conflit durablement.

La RDC et le Rwanda signent un accord de paix négocié par les États-Unis : quelles sont ses chances de succès ?


L’accord entre la RDC et le Rwanda présente de nombreuses lacunes

Il est difficile de dire à ce stade si la RDC et le Rwanda sont vraiment déterminés à instaurer la paix et si leur engagement sera suffisant.

Leur volonté affichée de respecter mutuellement leurs territoires et de renoncer à toute agression est un point important.

Mais le Rwanda a déjà mené des opérations militaires directes en RDC depuis les années 1990. L’accord évoque vaguement un « désengagement des forces » ou la levée de « mesures défensives » par le Rwanda, sans toutefois mentionner clairement le retrait des milliers de soldats rwandais présents dans l’est de la RDC.

Le gouvernement rwandais dirigé par Paul Kagame soutient également les groupes armés dominés par les Tutsis en RDC depuis le génocide rwandais de 1994. Le Mouvement du 23 mars (M23) est l’acteur militaire principal actuellement dans l’est de la RDC. Mais l’accord entre les gouvernements de la RDC et du Rwanda n’inclut pas le M23 ni d’autres groupes. Les deux gouvernements s’engagent uniquement à soutenir les négociations en cours entre la RDC et le M23 facilitées par le Qatar.

L’accord prévoit également la « neutralisation » d’un autre groupe armé, les Forces démocratiques pour la libération du Rwanda (FDLR), dominées par les Hutus. Ce groupe prétend protéger les réfugiés hutus rwandais en RDC, mais est considéré comme « génocidaire » par le gouvernement rwandais. Le groupe a réagi à ce plan en appelant à une solution politique et à un processus de paix plus inclusif.

Ce qui manque à l’accord

L’accord entre la RDC et le Rwanda comprend des dispositions essentielles pour les personnes les plus touchées par le conflit, telles que le retour des millions de personnes déplacées en raison des combats dans l’est de la RDC. Mais d’autres questions essentielles ne sont pas abordées.

Par exemple, hormis un engagement général à promouvoir les droits humains et le droit international humanitaire, il n’est fait aucune mention des violations massives des droits humains et des crimes de guerre qui auraient été commis par toutes les parties. Il s’agit notamment d’exécutions sommaires et de violences sexuelles et sexistes, y compris à l’encontre d’enfants.

Un mécanisme de justice et de réconciliation pour traiter ces violences à grande échelle aurait dû être envisagé. Cela a été le cas dans l’accord signé en 2016 entre le gouvernement colombien et les FARC (Forces armées révolutionnaires de Colombie), qui a connu un certain succès. Ce type de dispositif peut aider à prévenir de nouvelles violences.

Il envoie un message clair : les crimes ne resteront pas impunis. Cela aiderait également la population à se reconstruire et donnerait une meilleure chance à la paix.

Il n’existe pas de modèle unique. La justice dite « transitionnelle » – définie comme « l’ensemble des processus et mécanismes mis en place par une société pour faire face à un passé marqué par des abus à grande échelle, afin d’assurer la responsabilité, rendre justice et favoriser la réconciliation » – demeure un sujet controversé.

Par exemple, le fait de réclamer des procès pour crimes de guerre peut être perçu comme une menace pour un processus de paix encore fragile.

Mais depuis quelques décennies, les accords signés dans le monde, en Libye, en Centrafrique, et ailleurs, s’éloignent des amnisties générales. Ils comprennent de plus en plus de dispositions visant à garantir la responsabilité, en particulier pour les crimes graves. L’accord entre la RDC et le Rwanda reste muet sur ces questions.

Une autre lecture de l’accord

L’accord entre la RDC et le Rwanda est compliqué par le rôle de Washington et la poursuite de ses intérêts économiques.

Les deux États ont convenu de créer un comité de suivi conjoint, composé de membres de l’Union africaine, du Qatar et des États-Unis. L’accord prévoit aussi un cadre d’« intégration économique régionale ». Mais cette initiative est critiquée. Elle pourrait ouvrir la porte à une nouvelle forme d’ingérence étrangère dans les ressources minières du Congo.

Le pays est le plus grand producteur mondial de cobalt, par exemple, un métal essentiel pour le secteur des énergies renouvelables.

Certains y voient un « troc néocolonial » : la paix en échange de l’exploitation des ressources. Ce genre d’accord n’envoie pas un bon signal. Et il a peu de chances de régler un conflit largement alimenté, depuis des années, par l’exploitation de ces richesses.

What will batteries of the future be made of? Four scientists discuss the options – podcast

Source: The Conversation – UK – By Gemma Ware, Host, The Conversation Weekly Podcast, The Conversation

The majority of the world’s rechargeable batteries are now made using lithium-ion. Most rely on a combination of different rare earth metals such as cobalt or nickel for their electrodes. But around the world, teams of researchers are looking for alternative – and more sustainable – materials to build the batteries of the future.

In this episode of The Conversation Weekly podcast, we speak to four scientists  who are testing a variety of potential battery materials about the promises they may offer.

When lithium-ion batteries emerged in the 1990s, they were a huge breakthrough, says Laurence Hardwick, a professor of electrochemistry at the University of Liverpool in the UK. He explains that lithium-ion batteries “ became commercialised at the same time as the mobile electronics industry really took off”. But their subsequent use in electric cars now presents “a challenge of scale”, given the use of rare earth minerals within their components.

Hardwick is director of the Stephenson Institute for Renewable Energy, named after the 19th-century engineer George Stephenson – builder of the world’s first inter-city rail link between Liverpool and Manchester, which passed close by to the University of Liverpool’s campus.

Hardwick’s work focuses on what other materials could be used either in conjunction with lithium, or on their own, to diversify battery manufacturing away from rare earth metals. Part of this includes research on solid-state batteries, which use ceramic plates rather than a solvents to conduct the ions that provide the charge. “ Solid-state batteries offer a lot of potential energy-gaining benefits and safety benefits,” he says.

Sodium-ion is also being touted as a potential alternative to lithium-ion batteries. Robert Armstrong, principal research fellow in chemistry at the University of St Andrews in Scotland, is part of a consortium of UK-based researchers working on questions around sodium-ion batteries, including what type of electrodes and electrolytes work best.

Like potassium-ion, which is also a potential battery candidate, sodium-ion is heavier than lithium-ion, but Armstrong says sodium is  fairly evenly abundant: “So you don’t have the supply issues that might affect lithium-ion, and you’re not like to see the same price volatility.”

Some Chinese manufacturers in China, such as BYD and CATL, are pushing ahead with sodium-ion batteries for cars, despite the fact they’re heavier than lithium-ion batteries. There’s also interest in sodium-based technology in countries in the Arabian Gulf that use desalination plants. “They’ve got all this sodium kicking around. Why not make use of it?” says Armstrong.

Batteries which biodegrade

Other researchers are looking at how to make batteries out of plant-based materials that are biodegradable. Bill Yen, a PhD candidate in electrical engineering at Stanford University, is part of a team who are developing Terracell, a type of battery that generates power using microbes in the soil.

Their inspiration was how to power environmental sensors in damp environments without leaving lots of electronic waste behind at the end of the battery’s life. Terracell won the energy category of the Prototypes for Humanity 2024 event in 2024 in Dubai, a  showcase for sustainable solutions to the world’s problems.

Also in Dubai was Ulugbek Asimov, a professor of mechanical and construction engineering at Northumbria University in the UK, who is developing BioPower Cells, a type of rechargeable battery made from waste products such as coffee which doesn’t contain any rare earth metals. “  And at the end of its lifespan, we drop it into boiling water and it will be turned into liquid ionic fertilizer,” Asimov said.

Applications are now open for early career researchers to submit their projects for the Prototypes for Humanity 2025 awards and showcase in Dubai.

New discovery at Cern could hint at why our universe is made up of matter and not antimatter

Source: The Conversation – UK – By William Barter, UKRI Future Leaders Fellow, University of Edinburgh

Why didn’t the universe annihilate itself moments after the big bang? A new finding at Cern on the French-Swiss border brings us closer to answering this fundamental question about why matter dominates over its opposite – antimatter.

Much of what we see in everyday life is made up of matter. But antimatter exists in much smaller quantities. Matter and antimatter are almost direct opposites. Matter particles have an antimatter counterpart that has the same mass, but the opposite electric charge. For example, the matter proton particle is partnered by the antimatter antiproton, while the matter electron is partnered by the antimatter positron.

However, the symmetry in behaviour between matter and antimatter is not perfect. In a paper published this week in Nature, the team working on an experiment at Cern, called LHCb, has reported that it has discovered differences in the rate at which matter particles called baryons decay relative to the rate of their antimatter counterparts. In particle physics, decay refers to the process where unstable subatomic particles transform into two or more lighter, more stable particles.

According to cosmological models, equal amounts of matter and antimatter were made in the big bang. If matter and antimatter particles come in contact, they annihilate one another, leaving behind pure energy. With this in mind, it’s a wonder that the universe doesn’t consist only of leftover energy from this annihilation process.

However, astronomical observations show that there is now a negligible amount of antimatter in the universe compared to the amount of matter. We therefore know that matter and antimatter must behave differently, such that the antimatter has disappeared while the matter has not.

Understanding what causes this difference in behaviour between matter and antimatter is a key unanswered question. While there are differences between matter and antimatter in our best theory of fundamental quantum physics, the standard model, these differences are far too small to explain where all the antimatter has gone.

So we know there must be additional fundamental particles that we haven’t found yet, or effects beyond those described in the standard model. These would give rise to large enough differences in the behaviour of matter and antimatter for our universe to exist in its current form.

Revealing new particles

Highly precise measurements of the differences between matter and antimatter are a key topic of research because they have the potential to be influenced by and reveal these new fundamental particles, helping us discover the physics that led to the universe we live in today.

Differences between matter and antimatter have previously been observed in the behaviour of another type of particle, mesons, which are made of a quark and an antiquark. There are also hints of differences in how the matter and antimatter versions of a further type of particle, the neutrino, behave as they travel.

The new measurement from LHCb has found differences between baryons and antibaryons, which are made of three quarks and three antiquarks respectively. Significantly, baryons make up most of the known matter in our universe, and this is the first time that we have observed differences between matter and antimatter in this group of particles.

The LHCb experiment at the Large Hadron Collider is designed to make highly precise measurements of differences in the behaviour of matter and antimatter. The experiment is operated by an international collaboration of scientists, made up of over 1,800 people based in 24 countries. In order to achieve the new result, the LHCb team studied over 80,000 baryons (“lambda-b” baryons, which are made up of a beauty quark, an up quark and a down quark) and their antimatter counterparts.

Crucially, we found that these baryons decay to specific subatomic particles (a proton, a kaon and two pions) slightly more frequently – 5% more often – than the rate at which the same process happens with antiparticles. While small, this difference is statistically significant enough to be the first observation of differences in behaviour between baryon and antibaryon decays.

To date, all measurements of matter-antimatter differences have been consistent with the small level present in the standard model. While the new measurement from LHCb is also in line with this theory, it is a major step forward. We have now seen differences in the behaviour of matter and antimatter in the group of particles that dominate the known matter of the universe. It’s a potential step in the direction of understanding why that situation came to be after the big bang.

With the current and forthcoming data runs of LHCb we will be able to study these differences forensically, and, we hope, tease out any sign of new fundamental particles that might be present.
