    What Happens to Harvard If Trump Successfully Bars Its International Students?

    by

    If President Trump makes good on all his threats, Harvard may lose much of its influence and prestige. It could also become even harder to afford.As President Trump and his team dialed up the pressure on Harvard University last month, threatening to bar its international students, the school issued what was at once a warning and a plea.“Without its international students, Harvard is not Harvard,” school officials wrote in a lawsuit asking a judge to stop the federal government’s actions.It left unsaid what Harvard, if it were no longer Harvard, would become.It’s a scenario that some inside Harvard are beginning to imagine and plan for as the Trump administration lobs attacks from all angles, seeking to cut the university off from both students and billions of dollars in federal funding.Top leaders at Harvard, one of the nation’s oldest universities, including its provost, John F. Manning, a conservative legal scholar who once clerked for the former Supreme Court justice Antonin Scalia, are meeting more frequently to strategize.The school’s board of trustees, the Harvard Corporation, has discussed whether hundreds, if not thousands, of people will need to be laid off.And on 8:30 a.m. Zoom calls once or twice a week, administrative officials meet with senior leaders of Harvard’s undergraduate and graduate schools to share updates about the latest Trump developments, which keep coming rapid-fire.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Gun Deaths of Children Rose in States That Loosened Gun Laws, Study Finds

      by

      Researchers looked at firearm fatalities in the 13 years immediately after the Supreme Court limited local governments’ ability to restrict gun ownership.Firearm deaths of children and teenagers rose significantly in states that enacted more permissive gun laws after the Supreme Court in 2010 limited local governments’ ability to restrict gun ownership, a new study has found.In states that maintained stricter laws, firearm deaths were stable after the ruling, the researchers reported, and in some, they even declined.Guns are the leading cause of death in the United States for people under 18. Dr. Jeremy Faust, an emergency room doctor at Massachusetts General Brigham Hospital in Boston, who was the study’s lead author, said he was dismayed to find that most of the children’s deaths were homicides and suicides.“It’s surprising how few of these are accidents,” Dr. Faust said. “I always thought that a lot of pediatric mortality from guns is that somebody got into the wrong place, and I still think safe storage is important, but it’s mostly homicides and suicides.”John Commerford, executive director of the NRA Institute for Legislative Action, called the study “political propaganda masquerading as scientific research.”The study, published Monday in JAMA Pediatrics, examined the 13-year period after the June 2010 Supreme Court ruling that the Second Amendment, which protects an individual’s right to bear arms, applies to state and local gun-control laws. The decision effectively limited the ability of state and local governments to regulate firearms.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Ancient Trees, Dwindling in the Wild, Thrive on Sacred Ground

      by

      The Putuo hornbeam, a hardy tree that thrives in the damp air by the East China Sea, could be easily overlooked by visitors to the Huiji Temple on an island in the Zhejiang Province.The tree has an unremarkable appearance: spotty bark, small stature and serrated leaves with veins as neatly spaced as notebook lines. But its status is singular. As far as conservationists can tell, no other mature specimen of its species is alive in the wild.The holdout on the island, Mount Putuo, has been there for about two centuries. And according to a study published Wednesday in the journal Current Biology, its setting may have been its salvation.The study found that religious sites in eastern China have become refuges for old, ancient and endangered trees. Since the early years of the Common Era, Buddhist and Taoist temples have sheltered plants that otherwise struggled to find a foothold, including at least eight species that now exist nowhere else on earth.“This form of biodiversity conservation, rooted in cultural and traditional practices, has proven to be remarkably resilient, persisting even in the face of modern civilization and rapid economic development,” said Zhiyao Tang, a professor of ecology at Peking University and one of the study’s authors.The trees survived at religious sites in part because they were planted and cultivated there. The report noted that Buddhism and Taoism emphasize spiritual association with plants and the temples tended to be left undisturbed, shielding the areas from deforestation.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Is Peeing ‘Just in Case’ Bad for Your Bladder Health?

      by

      Q: A urologist recently told me I shouldn’t go to the bathroom “just in case.” Is that true?As children, many of us were encouraged to pee before we left the house or whenever a bathroom was nearby. There was a good reason: using the bathroom “just in case” can help prevent accidents among children prone to “holding it.”Urologists call this practice “convenience” or “proactive” voiding, and people of all ages do it, often before heading out the door or going to sleep.An occasional “just in case” bathroom break won’t do much harm, said Dr. Ariana Smith, a professor of urology at the University of Pennsylvania Perelman School of Medicine. But doing it several times a day, she said, can increase the likelihood of bladder issues by disrupting the natural feedback loop between your bladder and your brain.How does peeing ‘just in case’ affect bladder health?To understand why proactive voiding can be harmful, it helps to know how the bladder works. As your kidneys filter blood to remove waste, they produce urine, which is carried to your bladder. Women can typically hold up to 500 milliliters of urine, or around two cups, in their bladders; men can store 700 milliliters, or nearly three cups.We generally feel the urge to use the bathroom well before we hit that limit, when our bladder contains between 150 and 250 milliliters of liquid. As the bladder fills up, it sends nerve signals to the brain, letting us know it’s time to go.The experts we spoke with said that when you pee “just in case,” your bladder starts alerting your brain too early, before having the standard amount of urine. This disruption can reduce “the volume your bladder can hold over time,” said Siobhan Sutcliffe, an epidemiologist and professor of surgery at Washington University.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Exercise Extends Life for People With Cancer, Study Shows

      by

      The trial, in people treated for colon cancer, showed clear evidence that an exercise program lowered the risk of disease recurrence and death.A first-of-its kind study adds powerful new evidence to research showing that exercise improves cancer survival.The study, a randomized controlled trial of nearly 900 patients at 55 cancer centers in six countries, showed that people who participated in a structured exercise program lived longer without their cancer coming back and without the occurrence of new cancers. Participants in the exercise program had a 37 percent lower risk of dying and a 28 percent lower risk of recurrent or new cancer than those in the control group.Earlier research had suggested such a benefit, but the data were from observational studies that did not prove a causal link, experts said.“We now have definitive evidence that exercise is not just an intervention for quality of life and fitness. This is an intervention that improves survival and should be standard of care,” said Dr. Christopher Booth, the senior author of the paper and a professor of oncology at Queen’s University in Canada.The study, which was published Sunday in the New England Journal of Medicine, looked at patients with Stage III or high-risk Stage II colon cancer who received standard surgery and chemotherapy treatment. Researchers randomly assigned these patients to a control group, which received educational materials promoting physical activity and healthy nutrition, or to a treatment group, which also received support from a “physical activity consultant” — a hybrid of personal trainer and life coach — over three years to increase their aerobic exercise and sustain it. Patients could choose a number of activities, such as biking, jogging, swimming or kayaking, but most opted for a brisk walk of 45 minutes four times a week, Dr. Booth said.Eighty percent of patients in the exercise group remained disease-free after five years, compared to 74 percent of patients in the control group. After eight years, the exercise program had prevented one death for every 14 people who participated in the exercise arm of the study.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Trump Officials Unveil Budget Cuts to Aid for Health, Housing and Research

      by

      The new blueprint shows that a vast array of education, health, housing and labor programs would be hit, including aid for college and cancer research.The Trump administration on Friday unveiled fuller details of its proposal to slash about $163 billion in federal spending next fiscal year, offering a more intricate glimpse into the vast array of education, health, housing and labor programs that would be hit by the deepest cuts.The many spending reductions throughout the roughly 1,220-page document and agency blueprints underscored President Trump’s desire to foster a vast transformation in Washington. His budget seeks to reduce the size of government and its reach into Americans lives, including services to the poor.The new proposal reaffirmed the president’s recommendation to set federal spending levels at their lowest in modern history, as the White House first sketched out in its initial submission to Congress transmitted in early May. But it offered new details about the ways in which Mr. Trump hoped to achieve the savings, and the many functions of government that could be affected as a result.The White House budget is not a matter of law. Ultimately, it is up to Congress to determine the budget, and in recent years it has routinely discarded many of the president’s proposals. Lawmakers are only starting to embark on the annual process, with government funding set to expire at the end of September.The updated budget reiterated the president’s pursuit of deep reductions for nearly every major federal agency, reserving its steepest cuts for foreign aid, medical research, tax enforcement and a slew of anti-poverty programs, including rental assistance. The White House restated its plan to seek a $33 billion cut at the Department of Housing and Urban Development, for example, and another $33 billion reduction at the Department of Health and Human Services.Targeting the Education Department, the president again put forward a roughly $12 billion cut, seeking to eliminate dozens of programs while unveiling new changes to Pell grants, which help low-income students pay for college.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      China to Launch Tianwen-2 Mission to Capture Pieces of Near-Earth Asteroid

      by

      The robotic Tianwen-2 spacecraft will collect samples from Kamoʻoalewa, which some scientists suspect is a fragment of the moon.China has a space station and, in just a few short years, has landed robots on the moon and Mars. This week the country’s space agency is targeting new, far-flung destinations and setting off for an asteroid that could contain secrets that explain how Earth and the moon formed.The country’s Tianwen-2 spacecraft is set to lift off aboard a Long March 3B rocket from the Xichang Satellite Launch Center in southwest China some time on Thursday (it will be Wednesday in New York).After about a year, the robotic mission will arrive at 469219 Kamoʻoalewa, a near-Earth asteroid. There, it will perilously try to scoop up some rocky matter, and then swing back around to Earth. A capsule filled with geologic treasure would then plunge toward the planet for retrieval by scientists in late 2027.If Tianwen-2 pulls this off, China will become the third nation — after Japan and the United States — to retrieve pristine material from an asteroid.“All Chinese planetary scientists are now finger-crossed for this historic mission,” said Yuqi Qian, a lunar geologist at the University of Hong Kong.The spacecraft also has a secondary target, an unusual comet that it could study as part of an extended mission.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Trump Wants $3 Billion in Harvard Grants Redirected to Trade Schools

      by

      In a social media post, the president mused about redirecting $3 billion in research grant funding that his administration has frozen or withdrawn, but he gave no details.President Trump floated a new plan on Monday for the $3 billion he wants to strip from Harvard University, saying in a social media post that he was thinking about using the money to fund vocational schools.“I am considering taking THREE BILLION DOLLARS of Grant Money away from a very antisemitic Harvard, and giving it to TRADE SCHOOLS all across our land,” Mr. Trump posted on Truth Social, his social media platform.The announcement, among the president’s Memorial Day social media messages, did not appear to refer to any new cut in funding, but rather to a redistribution of money the administration already announced it had frozen or stripped from Harvard and its research partners.Mr. Trump gave no details about how such a plan would work.The message was accompanied by yet another post accusing Harvard of being slow to respond to the administration’s requests for information on “foreign student lists.” Mr. Trump said his administration wanted them in order to determine how many “radicalized lunatics, troublemakers all, should not be let back into our Country.”The posts seemed intended to keep up public relations pressure on Harvard, the nation’s oldest and wealthiest university. Harvard is engaged in an epic battle with the White House, rooted in the administration’s claims that the university tolerates antisemitism and promotes liberal ideology.Harvard declined on Monday to comment on the president’s post.The university is battling the White House in federal court in Boston to secure the reinstatement of grants and contracts that the government has frozen or withdrawn, amounting to more than $3 billion. In a separate lawsuit, the university is also fighting Mr. Trump’s plan to take away the university’s right to admit international students.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      A Blood Test for Alzheimer’s: What to Know

      by

      The test may make it easier to identify whether people with memory and thinking problems have Alzheimer’s or not.A blood test that can help diagnose Alzheimer’s disease has received clearance from the Food and Drug Administration. This is a step toward a goal of scientists and doctors to one day be able to diagnose a confounding illness with the prick of a finger. But there is still a long way to go.Here is what to know:What is the test, and how should it be used?The test, manufactured by Fujirebio Diagnostics, is intended to be used only by specialists in Alzheimer’s, the F.D.A. said. Its mouthful of a name — Lumipulse G pTau217/ß-Amyloid 1-42 Plasma Ratio — describes what the test measures: levels of two proteins, amyloid and tau, that are hallmarks of Alzheimer’s disease.In people who develop Alzheimer’s, amyloid begins to accumulate and form plaques in the brain more than 20 years before any symptoms of cognitive impairment. Tau accumulates later, forming tangles in the brain, and is much more closely correlated with cognitive decline.Can people who don’t have memory problems take the blood test?No. The F.D.A., and Alzheimer’s experts, emphasized that the blood test should be given only to people who are already experiencing cognitive decline and are ages 55 and older. Moreover, it should not be used on its own to diagnose or to rule out Alzheimer’s.“Other clinical evaluations or additional tests should be used for determining treatment options,” the F.D.A. said in a statement, adding that “the results must be interpreted in conjunction with other patient clinical information.”The current gold standard for diagnosing Alzheimer’s still involves either imaging using PET scans, which are expensive, or spinal taps, which are invasive. The blood test can help flag the presence of the Alzheimer’s-related proteins, and doctors might then order confirmatory testing with one of the other methods.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
