Imagine you and I are playing a simple game of chance. We each throw $50 into a pot and start flipping a coin. Heads, you get a point; tails, I get one. The first person to reach 10 points walks away with the full $100. The game gets underway, and the score is currently eight to six in your favor. Suddenly, my phone rings: there’s an emergency, and I must leave in a hurry. Now we have a problem. You don’t want to just hand me my $50 back because you’re winning. But I’m reluctant to give you the whole pot because I still have a chance to hit a lucky streak and mount a comeback. What is the fairest way to split the cash?
Known as the “problem of points,” or “problem of the division of the stakes,” this puzzle stumped mathematicians for more than 150 years. And it did so for good reason: probability theory hadn’t been invented when the problem was first posed. Two greats of 17th-century math, Blaise Pascal and Pierre de Fermat, corresponded about the problem in a famous series of letters. They not only discovered the correct way to share the pot but also created the foundations of modern probability theory in the process. To this day, the solution is the basis for risk assessments of all kinds, helping us make smarter bets on everything from buying a stock to insuring a home along a coastline.
In 1494, Italian mathematician Luca Pacioli first took an early crack at the problem of points in his textbook, the title of which translates to Summary of Arithmetic, Geometry, Proportions and Proportionality. He proposed that players should split the pot in proportion to how many points they each have at the time of interruption. In our running example, you have won eight of the 14 flips thus far. According to Pacioli’s solution, you would take eight fourteenths of the pot, which equals about $57.14. I would take the remaining six fourteenths. The solution sounds sensible, but more than 50 years later, Niccolò Fontana “Tartaglia” noticed that it failed in cases where the point ratio between players was extreme. What if the interruption came after a single coin toss? Under Pacioli’s rule, the winner of that one flip would take the entire pot, even though the game was far from decided. This would be clearly unfair—and the problem of points is all about seeking a fair split.
Tartaglia proposed an alternative method. Imagine that, in our hypothetical game, you’re ahead by two flips. You have one fifth of the 10 flips needed to win. Because that’s one fifth closer to the goal, Tartaglia reasoned that you should get your full stake back and take one fifth of my stake: the original $50 you put in plus one fifth of my $50, for a total of $60. This new approach seems to operate more equitably, especially at the extremes. Now if the game got interrupted after one flip, then the winner of that flip would take only one tenth of their opponent’s stake instead of all of it. While Pacioli’s method rewards the winning player based on the size of their lead relative to the number of flips thus far, Tartaglia’s method rewards them based on the size of their lead relative to the total length of the game. Tartaglia doubted his own innovation, though, writing, “In whatever way the division is made there will be cause for litigation.” He believed that no perfect mathematical solution existed and that the problem was designed to cause arguments. It turns out he was at least right to doubt his own solution. Imagine that one player had 199 points and that the other had 190 points during a game with a goal of 200 points. Tartaglia would award the first player only nine two-hundredths of their opponent’s stake, or $2.25, even though their opponent would need 10 tails in a row to win. The first player’s measly payout hardly seems to reflect their overwhelming likelihood of winning at that stage of the game.
The debate went nowhere until the mid-17th century, when a French gambler and intellectual socialite enlisted the help of mathematician Blaise Pascal. Pascal immediately saw that the solution lay not in the score at the time of interruption but in the future possibilities of the score, and he wrote to his friend and fellow mathematician Pierre de Fermat to help him prove it. Their correspondence yielded two completely unique approaches to the problem. Amazingly, their disparate approaches always arrived at the same solution. This convergence sealed their confidence in their results, and mathematicians now agree that they had found the fairest way to divide the stakes.
Fermat’s solution was to look at all possible continuations of the game after the point at which it was interrupted and count the number of those continuations that result in a win for each player. A fair percentage of the total pot awarded to a player should be the percentage of possible futures in which that player wins the game. Take our recent example game’s score of eight to six with a goal of 10 points; Fermat would notice that the game must end within five coin flips. If the first player won one flip and the second won three, then they would be tied at nine to nine, and the game would end on the next flip. If the game stopped at this point, Fermat’s method for dividing the pot would list all possible outcomes of those five coin flips and then tally the ones that amassed 10 points for each player. In some of those possible futures a player will win in fewer than five flips, but that’s okay: we can imagine that if the game ends early, the players flip the coin a few extra times just to make the accounting easier. The figure below reveals the answer to our puzzle. The first player wins in 26 out of the 32 possible continuations of the game, so they are due 26 / 32 = 81.25 percent of the pot, or $81.25.
Pope Leo XIV on Thursday denounced the Iranian regime’s killing of protesters but stressed that, “as a pastor,” he cannot support the US-Israeli war with Iran.
The pope’s remarks, made to reporters on board the papal plane returning from his trip to Africa, follow President Donald Trump’s attacks on the pontiff for his stance on the Middle East conflict.
During an in-flight press conference, the pope also addressed the topic of immigration, saying that in some cases immigrants are being treated “worse than pets.”
The first American pope told CNN last month that he hoped Trump would find an “off-ramp” to end the war in Iran, and he spoke out against justifying conflict on religious grounds. But in the hours before the pope took off for Africa on April 13, the US president sharply criticized the pope.
“As a pastor, I cannot be in favor of war,” Leo told reporters flying with him from Malabo, Equatorial Guinea. “I would like to encourage all to make efforts to look for answers that come from a culture of peace and not from a place of hate and division.”
Leo said the US and Israeli bombing of Iran has created a “chaotic situation for the global economy,” along with “a whole population in Iran, of innocent people, which is suffering because of this war.” Highlighting the human cost of conflict, the pope revealed that he carries a photo of a Lebanese Muslim boy, who had carried a sign welcoming the pontiff to the country at the end of last year and who was killed in the war.
The question of Iran is evidently very complex,” he told reporters flying with him from Malabo, Equatorial Guinea, to Rome. “The negotiations they are trying to do — one day Iran says yes, and the United States says no, and vice versa, and we don’t know where it goes.”
Regardless of whether “there is regime change or no regime change,” the emphasis should be on preventing the “death of so many innocents,” Leo said. He cited a letter from the families of school children who died on the first day of the Iran war.
“For me, if there is regime change or not, it’s not clear what the regime is at this moment after the first days of the … attacks of Israel and the United States against Iran,” he said.
The pope, who alternated between English, Spanish, and Italian when answering questions, also criticized the Iranian regime’s killing of protesters in his first remarks on the topic.
Asked if he condemned Tehran’s deadly crackdown on protests in January, Leo said: “I condemn all actions that are unjust. I condemn the taking of people’s lives. I condemn capital punishment. I believe that human life is to be respected,” Leo, 70, said. “When a regime, when a country, takes decisions which take away the lives of people unjustly, then obviously that is something that should be condemned.”

On a sweltering night in August 2024, moments before Robert F. Kennedy Jr. endorsed then-candidate Donald J. Trump at a packed rally in Arizona, a conservative young wellness podcaster named Alex Clark had a fleeting backstage conversation with the once-and-future president.
“I said, ‘Mr. President, please keep talking about food and pharma; this has a massive impact with undecided female voters,’ ” recalled Ms. Clark, now a leading conservative voice in Mr. Kennedy’s “Make America Healthy Again” movement. Witnessing the two men join forces, she said, “was the greatest political moment of my life.”
Not quite two years later, the MAHA movement is still a political force. But MAHA leaders warn that many of those who embrace the cause are dispirited and disillusioned — and that when the November elections come around, some may just stay home.
Six of the movement’s most prominent leaders, who together have millions of social media followers, said in separate interviews that the mostly white, mostly female voters who followed Mr. Kennedy into Mr. Trump’s camp are so disappointed with the president that Republicans risk losing them. But they said Democrats would need to work hard to win their votes.
“Republicans would be stupid, moronic,” Ms. Clark said, “to let these voters just slip through our fingers.”
The MAHA PAC, run by Tony Lyons, a conservative-leaning publisher and close Kennedy ally, launched an ambitious initiative in March to raise $100 million to elect “MAHA-aligned, Trump-endorsed” Republicans — a goal that would far exceed the $1.2 million the group raised through the end of February, according to recent campaign finance filings.
But the MAHA leaders who spoke to The New York Times said their voters belong to no individual party. They will vote the person, not party.
“The only thing that matters is action,” said Zen Honeycutt, who founded Moms Across America, an advocacy group that threw its weight behind Mr. Kennedy. “Not a political party.”
Leslie Manookian, a former Wall Street executive who became a homeopath and founded the Health Freedom Defense Fund, which fights vaccine and other medical mandates, said this about MAHA: “I don’t think it’s led by anybody. It’s a populist, grass roots movement.”
A Loose Coalition
Long before Mr. Kennedy gave it a Trump-inspired nickname, the MAHA movement was a loose-knit collection of groups.
Vaccine skeptics fought mandates under the “health freedom” banner. Environmental activists fought chemical exposures, allying themselves with fans of organic food and alternative medicine. They are now held together by Mr. Kennedy, and a shared suspicion of government and industry.
Vaccine skeptics complain that the White House seems to be muzzling Mr. Kennedy on what had been his signature issue. Health and wellness activists are thrilled with Mr. Kennedy’s Eat Real Food agenda promoting red meat and rejecting processed foods, but are upset that Dr. Casey Means, a wellness influencer whose emphasis on diet as a way to combat chronic disease make her a MAHA heroine, is struggling to win Senate confirmation as surgeon general.
And both food and environmental activists feel deeply betrayed by Mr. Trump’s recent executive order aimed at ramping up production of glyphosate, the weedkiller marketed as Roundup, which some scientists suspect causes cancer. The president said he issued it on national security grounds to protect the food supply and because its core ingredient is used to make munitions.
“It’s very hard to support a movement that is labeled MAHA when two opposing things are happening at the same time,” said Vani Hari, a wellness personality who markets herself as “The Food Babe.” “It’s like, ‘Yes, we can eat all the real food we want, but it’s covered in Roundup.’ ”
Whether the MAHA moniker — a riff on MAGA, Mr. Trump’s acronym for Make America Great Again — survives is an open question. MAHA leaders say the components of their movement will thrive and grow no matter what it is called. Both Ms. Hari and Ms. Clark worry about getting MAHA voters to the polls.
“They have nowhere to go,” said Ms. Clark, who works for Turning Point U.S.A., the right-wing organization founded by Charlie Kirk. “They feel like their vote is useless. They have lost the energy. They have lost the enthusiasm. They feel like the Democrats don’t care about them. They feel like the Republicans lied to them, and they’re not planning on voting.”

Every day, the human body replaces billions of cells, flushing out the old and generating the new, healthy ones. The average lifespan of a red blood cell is just under four months, while skin cells last about a month, and those in the intestinal lining exist for just a few days. This turnover is the default, but there’s one part of the body in which humans and other mammals don’t seem geared toward generating new cells: the brain.
Aging and damaged brain cells, or neurons, can cause memory problems and limit the brain’s ability to recover from illnesses. Some scientists have posited that if we could just turn on the ability to make new neurons in the brain—a process called neurogenesis—some of these deleterious changes might be reversed. But a new study suggests neurogenesis may be more destructive than we thought, adding weight to a countertheory that our brain’s apparent limitation is actually an evolved protection.
“Birds, reptiles, fish: they all have widespread neurogenesis throughout their forebrains throughout life,” says Benjamin Scott, the study’s senior author and an assistant professor at Boston University. “It’s really in mammals where we see this restricted.”
In the new paper, published today in Current Biology, Scott and his colleagues analyzed the brains of Zebra Finches, small songbirds that undergo neurogenesis throughout their life. The researchers wanted to know how adult neurogenesis affected surrounding brain tissue, so they used an electron microscope to watch how new neurons reach their destination in the brain. Researchers had previously assumed neurons might follow structures in the brain called glial scaffolds, which guide neurons to the right place during development. But Scott and his team observed that the new neurons tunneled straight through older neural pathways and that the new brain cells were more rigid than “squishy” mature neurons.
“They’re just sort of everywhere in the tissue,” Scott says of the new neurons. “They’re touching all the mature cells. They’re right in the middle of all of the action.”
Because adult brains are done growing, they don’t have room for new structures, so the tunneling wasn’t a complete surprise to researchers. Still, understanding the destructive side of neurogenesis—doing away with older paths through the brain to make new connections—could help researchers understand why mammals limit this ability in adults.
“One of the things that this study has revealed to us is that, as the new neurons move through the brain, they seem to be pushing or deforming the tissue,” Scott says. “You could imagine that they might be altering the circuit, breaking connections that are the basis of stored memories.”
Humans and other mammals might have evolved to limit adult neurogenesis to preserve important long-term memories, he and his colleagues speculate. But because mammals and birds are so different, it’s hard to know if the same tunneling process happens in mammalian brains, too.
“The human and bird forebrains have different organization patterns…, so some caution is called for in extending parallels to the level of brain circuits and cells,” says Eliot Brenowitz, a neurobiologist at the University of Washington, who was not involved in the new study.

After a rare disease diagnosis left her partially paralyzed, Marion Jones worked her way back from being reliant on a wheelchair to running marathons.
Jones credits her recovery to the doctors and therapists in Boston who helped her relearn how to walk — and eventually run again.
Now, she is running the Boston Marathon as a full-circle tribute to the hospital that treated her, and in support of the rare disease community.
In 2020, Marion Jones was living in Boston working for a green energy company, when she decided it was time to see a doctor. For about a year, she had been experiencing nagging health problems.
“For me, it started to show up as this burning sensation in various parts of my body. It would maybe last for 10 seconds, and then it would migrate to another part of my body,” she said.
When she began to have excruciating back pain, she made an appointment.
The first doctor she saw couldn’t explain the symptoms, but a second doctor suspected multiple sclerosis, or MS. An MRI quickly ruled MS out, and Jones returned to her normal life.
But after developing a headache that lasted for several months, a friend convinced her to visit the emergency room. A doctor prescribed a muscle relaxer and released her, but just 72-hours later, Jones found herself back in the hospital — this time with difficulty moving the right side of her body.
It was there at Beth Israel Lahey that Jones received news that would change her life forever. She was diagnosed with neuromyelitis optica, or NMO — a rare, autoimmune disorder that primarily affects the optic nerves and the spinal cord.
Sometimes referred to as the “cousin of MS”, NMO typically causes severe, rapid, and destructive attacks on the optic nerves and spinal cord, and can lead to permanent vision loss or paralysis.
Things quickly spiraled for Jones. A flare-up caused her to experience partial paralysis, and doctors admitted her to the intensive care unit of the hospital.
Jones was admitted into the ICU after a rare disease diagnosis left her temporarily paralyzed.

But Jones, who had a limited ability to walk and care for herself, needed more specialized care and was eventually admitted to the Encompass Rehabilitation Hospital of New England, a hospital that specializes in inpatient rehab.
For Jones, who was an avid runner prior to her diagnosis, it was a particularly devastating blow.
“In 2019, I had run 35 five Ks in 35 weeks … to not being able to walk or get myself to the bathroom. It was just something that I had never thought would happen to me,” Jones said.
Jones, who had no family in Boston, said the doctors and therapists at Encompass set her on a path towards recovery from day one.
“They really became family for me. In the absence of my family. They were so patient,” Jones said.
Dr. Daniel Lyons, the medical director of Encompass Rehabilitation Hospital of New England, was a member of that team.
“Marion had a situation where her autoimmune illness affected the cervical spinal cord injury. So essentially … she had a spinal cord injury. She had lost her strength in her arms, her legs. There was sensory loss. She also had a lot of pain and muscle tightness from the spinal injury,” Lyons said.
Jones was forced to use a wheelchair after she lost her ability to walk following a diagnosis of NMO. Marion Jones

Jones’ rehab schedule was grueling — three hours of intense therapy every day. But Lyons said the work paid off. “She made an incredible amount of progress from the time she came into the rehab hospital, she was using a wheelchair, non ambulatory. [In] a relatively short time, she had progressed through walking in parallel bars to a walker, and she was able to walk short distances with a walker when she left inpatient rehab hospital.”
Outpatient therapy continued for Jones, and it was during one of those sessions that her therapist challenged her to run on a treadmill. It was difficult for Jones, and she says she could only run for about 30 seconds, but it reawakened her desire to run again.
“After that session, I got home and I got on the bike path and I said, ‘I’m going to see if I can run for a minute,’” Jones said. “As the weeks progressed, the minute became a half a mile, and that half a mile became a mile. And so that’s where I started, really just getting in the mindset of running again.”
Eventually, she regained her form. Jones says she never set out to run a marathon, but that’s where her path led her. Since her diagnosis, Jones has run in six marathons.
On the surface, it appeared as though Antoinette Del Rio was a successful 20-something. She had a flourishing career in advertising, took frequent vacations, and enjoyed an active social life.
But Ms. Del Rio was drinking too much, using weed as a coping mechanism, and spending weekends holed up in her New York City apartment. She had also fallen into debt from impulsive overspending and frequently fought with her friends.
Soon she began to notice a troubling pattern in all of her relationships: They felt either euphoric or devastating, with no middle ground. A seemingly small conflict could cause her to “completely lash out without thinking of any of the consequences,” said Ms. Del Rio, now 33. Sometimes she was so angry that she would pull out her hair or dig her nails into her skin “as hard as possible.”
In 2022, her primary care doctor pieced it all together: Ms. Del Rio was showing telltale symptoms of borderline personality disorder, or B.P.D., a condition characterized by volatile relationships and emotions, alongside reckless behavior and an empty sense of self.
B.P.D. is challenging to effectively treat, which can “scare the pants off therapists,” said Dr. Lois W. Choi-Kain, director of the Gunderson Personality Disorders Institute at McLean Hospital in Belmont, Mass. But people can — and do — get better, she added, even those with additional issues like substance use and disordered eating.
Dr. Choi-Kain said that she had seen people who were very ill develop the skills to “feel good about themselves, and then be able to manage a relationship differently,” she said.
What is a borderline personality?
Mental health practitioners define borderline personality disorder as a pattern of instability in someone’s relationships, self-image, and emotions.
People with B.P.D. have a tendency to do things without thinking, sometimes engaging in activities like reckless sex, substance abuse, or self-harm, which is often what leads them to treatment.
It is estimated that B.P.D. affects 1.6 percent of the population; it isn’t considered by mental health professionals to be rare, yet the disorder is often misdiagnosed at first because some of its symptoms can be mistaken for other conditions, such as bipolar disorder, depression, and attention-deficit hyperactivity disorder.
These conditions can also overlap with B.P.D., which further complicates the diagnosis. In fact, in 1938, B.P.D. was initially described as “borderline” by the psychoanalyst Adolph Stern because it borders on other conditions.
What are the signs and symptoms?
B.P.D. symptoms can include inappropriate outbursts of anger, feelings of emptiness, and desperate efforts to avoid feeling abandoned — for example, continually seeking reassurance or “testing” people to see if they will stay, said Sara Masland, an associate professor of psychological science at Pomona College and an expert in personality disorders.
Other features of B.P.D. include volatile relationships, an unclear sense of self, a tendency to self-harm, recklessness, and suicidal behavior. (Studies have found that as many as 10 percent of people who had B.P.D. died by suicide — a number far greater than that of the general population.)
Patients must have at least five symptoms to be diagnosed, according to the diagnostic manual used by mental health practitioners.
One of the defining features of borderline personality disorder is hypersensitivity — most people swing back and forth between being anxious or fearful of being criticized or disliked, and angry or paranoid when they feel as though people are rejecting them, Dr. Choi-Kain said.
One minute a patient might feel fine, then depressed, then intensely angry. This can lead to relationships that are full of conflict and devoid of peace, harmony, consistency, or depth, said Dr. Frank Yeomans, clinical professor of psychiatry at Weill Cornell Medical College, who has focused on the treatment and research of personality disorders for decades.
When things seem perfect, “you’re in heaven,” Dr. Yeomans added. But “as soon as there’s any flaw in what was nice, you go from heaven to hell.”
Despite the chaos in their personal relationships, people with B.P.D. often find it difficult to be alone, the experts said. This is partly because they don’t have a sense of who they are independent of other people.
“Oftentimes people with B.P.D. will over-rely on relationships to understand who they are, and that can make the relationship instability even more tenuous,” Dr. Masland said.
They may take on the traits of the people who they’re surrounded by or continually look to those people for validation. But deep down, they may feel empty.
How is B.P.D. treated?
Antidepressants and other medications can address B.P.D. symptoms, but only therapy will get to the root of the problem, the experts said. Many patients benefit from a “life renovation,” not only to help them get back on track but also to “change their concept of themselves and their relationship to other people,” Dr. Choi-Kain said.
In the United States, the most common modality to treat B.P.D. is dialectical behavior therapy or D.B.T., which focuses on helping people develop mindfulness and practical skills to manage their emotions.
Other evidence-based methods of treating B.P.D. include mentalization-based treatment, a type of therapy that aims to help people reflect realistically about what goes on in the minds of themselves or others during social interactions; and transference-focused psychotherapy, which uses the relationship dynamic between the therapist and client to explore how the client perceives others.
Humans are creatures of Earth and, in turn, at the mercy of Earth’s gravity. When we leave the confines of our home planet and enter the microgravity environment of space, our brain and body change. Studies have shown how microgravity can affect astronauts: it can throw off their balance, blur their vision, change the shape of their heart, and nudge the position of their brain inside their skull. And now a new study shows that microgravity, colloquially referred to as zero g, affects astronauts’ motor skills, too. Understanding these changes is critical for the future of human space exploration.
“It’s so important to interact with our environment,” says Philippe Lefèvre, senior author of the new study and a professor of biomedical engineering at the Catholic University of Louvain in Belgium. Unlike on Earth, in space, if an astronaut lets an object slip from their grasp, the consequences are not just different (that object doesn’t drop to the floor) but also possibly dire.
“This study highlights the brain’s remarkable ability to adapt to its physical environment,” says Lionel Bringoux, a professor at Aix-Marseille University in France, who also researches the effects of gravity on motor ability but was not involved in the new paper.
The new research involved 11 astronauts who lived onboard the International Space Station for at least five months. While on the station, they performed a series of experiments that tested how their rhythm and grip changed while they manipulated objects in zero g. Lefèvre and his colleagues found that astronauts tended to move slower in weightlessness and to grip an object more firmly than they would on Earth, as if the object was heavier than they knew it to be.
That was a surprise, Lefèvre says: “The fact that we were exposed to gravity from early childhood for years and decades, we cannot forget it, even after five to six months.” The astronauts knew that the object would feel weightless in zero g, but their brain predicted that it would feel as heavy as it would on Earth. And if the object was moving at speed, the astronauts would grab it and grip it even more tightly, he adds.
Bringoux says that this finding suggests “astronauts tend to apply a larger safety margin” than is strictly necessary for holding on to and moving objects to prevent any unexpected slips. It also suggests that astronauts reach an “optimal” level of adaptation to their weightless surroundings—their sensorimotor skills change enough to ensure they can safely and accurately hold on to and move things around in microgravity but not more than that.
The team ran further experiments to see how the astronauts’ motor skills readapted to the planet’s gravitational force just a day after they returned to Earth—both their grip and ability to move an object at a steady rhythm recovered quickly. “The adaptation that we had to gravity for decades [means] we do not fully adapt to microgravity, but the advantage is that when we go back to Earth, we readapt that very quickly to the Earth’s environment,” Lefèvre says. All in all, the study, which was published on Monday in the Journal of Neuroscience, took about 20 years from when it was first proposed to be completed.
Knowing how human brains adapt to different gravitational environments will be crucial for future space missions—although it’s an open question whether future astronauts traveling to the moon or Mars will show the same adaptations, Lefèvre says. There is some gravity on these worlds, and that could introduce risks, he adds. “Maybe the astronaut will feel gravity, and they will just go back to Earth mode, which is not appropriate because gravitational force [on Mars] is reduced,” he says.
“Studying these differences helps us anticipate and better prepare astronauts for such conditions,” Bringoux agrees.

Democrats maintained their electoral momentum on Tuesday by securing the passage of an aggressively gerrymandered House map in Virginia, which could deliver the party up to four extra seats as it tries to win back control of Congress.
National party leaders had been heavily invested in the outcome, with Representative Hakeem Jeffries of New York, the minority leader, helping orchestrate the statewide Virginia referendum with Democratic state legislators. Speaker Mike Johnson, hanging on to a slim majority, tried to rally the state’s Republicans.
Democrats sought to focus the campaign on President Trump, who instigated the nationwide redistricting fight last summer in Texas to help House Republicans in the midterms. A vote for a gerrymandered House map, Democrats argued, was a vote to help their party stop Mr. Trump’s agenda. The president stayed out of the contest until the final hours before Election Day, when he urged Virginians to block the map.
“Donald Trump tried to rig the midterm elections by gerrymandering the national congressional map,” Mr. Jeffries said in an interview on Tuesday night. “He has failed.”
Here are four takeaways from the election:
Changed maps
Action taken to change maps
+5+1+5+1
+1–2
+1
+2-4
+1–5
Democrats have fought to a draw in the clash over maps — for now.
The vote in Virginia erased the small structural advantage that Republicans had built in the country’s redistricting battle.
Republicans could still seize back their edge, however, with the prospect of a new map in Florida. And the Supreme Court may well set off a political earthquake with a ruling that upends a key provision of the Voting Rights Act, which could lead to more Republican gains.
But for now, Democrats have averted their fears from the start of the gerrymandering fight that Republicans could gain an overwhelming cartographic advantage. And with the political environment shifting in their favor, they are increasingly optimistic about winning back the House.

President Donald Trump’s recent executive order to accelerate research on psychedelic substances and their potential to treat mental health conditions could have wide-ranging science consequences. Experts say the directive could expedite studies on how psychedelic and hallucinatory drugs such as MDMA, psilocybin, LSD and ibogaine may be useful in medicine.
The executive order is “timely,” says Frederick Barrett, director of the Center for Psychedelic and Consciousness Research at Johns Hopkins University. “If this executive order can help us to really push forward promising therapies more quickly, then I think that is a good thing,” he says.
The order directs the administration to promptly evaluate and possibly approve psychedelics for medical purposes, which could also make it easier for researchers to study these substances. It also calls for allocating $50 million to support states’ psychedelic research, including on ibogaine, a compound found naturally in a Central African plant. Some early research suggests that ibogaine could help treat depression and substance use disorders in some people, but it has been shown to have serious side effects.
An estimated 15.4 million adults in the U.S. live with severe mental illness, according to the National Institutes of Health. Veterans are at particular risk: Research shows that suicide rates are nearly twice as high among veterans as they are in the general population. And existing drugs, such as selective serotonin reuptake inhibitors (SSRIs), that are designed to treat depression and other mental health conditions, aren’t always effective or accessible for everyone. An increasingly vocal cadre of researchers believe psychedelic substances could offer more effective treatments. And in some clinical trials, psilocybin, MDMA, and LSD have been found to have promising results in treating mental health conditions.
“We need better treatments,” says Alan Davis, director of the Center for Psychedelic Drug Research and Education at the Ohio State University. “We need to be able to help people, and I think psychedelic therapies will offer a new way in which to do that.”
But research into these drugs is slow and hard to do, not least because the U.S. government categorizes many psychedelics as Schedule I drugs, which means they are considered to be dangerous and to have a high potential for abuse and “no currently accepted medical use,” according to the definition in the Code of Federal Regulations. In most cases, the possession of such drugs is federally criminalized, and that adds significant hurdles for researchers who are trying to study their effects.
That’s part of the reason why very few therapies that use psychedelic drugs have been approved for use in the U.S. One of the most well studied psychedelics, MDMA, was set back in 2024 when, citing insufficient and flawed research, the Food and Drug Administration rejected a proposal to approve it as a treatment for post-traumatic stress disorder.
An FDA approval for one of these drugs would make further research “much less difficult” for scientists, Davis says. “You would change the requirements involved, which means we could do a lot more research for a lot less money on those treatments.”
He hopes that the executive order signals a change in the government’s approach. “It is really quite remarkable that a sitting president has made this statement as part of official executive orders,” Davis says.
“That act, in and of itself, is, I think, going to really escalate the research in this space,” he adds, “and hopefully make these treatments available to people that need them as quickly as possible.”
