The new director of the National Institutes of Health said today her highest priority is making NIH-funded clinical research more inclusive and more accessible to the public. “Equity will guide my approach to leading NIH,” Monica Bertagnolli told reporters in her first news conference, a 40-minute Zoom call. But Bertagnolli, a cancer surgeon who became head of NIH last month,...

The New England Journal of Medicine ( NEJM ) is launching a new series today examining its own complicity in perpetuating slavery and its legacy in the United States. In doing so, the 211-year-old journal joins several other publications and medical organizations that have, in recent years, interrogated harmful aspects of their own histories. In...

The Southeastern Archaeological Conference (SEAC) announced yesterday it will maintain a new image policy that prohibits its flagship journal from publishing photographs of objects buried with Indigenous ancestors. The decision reflects a vote held on the issue that concluded on 4 December. Many tribes with ties to the U.S. Southeast say seeing such images is a...

You’re only as old as you feel, so the adage goes. But new research suggests you may really be as old as your oldest organ. Scientists say they have developed a simple, blood test–based method to measure the speed of aging in individual organs such as the heart and brain. When an organ is substantially “older” than a person’s actual age, the risk of death and diseases related to...

Even after the billions of doses given during the pandemic, messenger RNA (mRNA) vaccines still hold surprises. A study out today reveals they may unexpectedly prompt cells to produce small amounts of unintended proteins. There is no evidence that these mistakes compromise the safety of the COVID-19 vaccines, which saved millions of lives, and the researchers have already proposed a fix...

Centrifuges: They’re not just for jet pilots and James Bond villains . Scientists in Germany have raised locusts in the spinning devices to see how the enhanced gravity affects their skeletons. It turns out that, just like in people, the mechanical stresses make their “bones” stronger. The findings, published today in Proceedings of the...

Polar bears are tough animals to track. Scientists must brave frigid Arctic landscapes to observe them, if they can spot them at all. And if they want to collect genetic information, they often have to dart and capture the animals—a risky proposition for both researcher and bear. A new approach may lend a paw to such efforts. In two new studies, scientists report that they can...

Scopus, a widely used database of scientific papers operated by publishing giant Elsevier, plays an important role as an arbiter of scholarly legitimacy, with many institutions around the world expecting their researchers to publish in journals indexed on the platform. But users beware, a new study warns. As of September, the database listed 67 “hijacked” journals—legitimate...

Once touted as the next big thing in cancer therapy, tumor-attacking viruses have been a letdown, failing in multiple clinical trials as far back as 1949. But preliminary results from a small phase 3 study presented at a conference last week suggest these unconventional cancer treatments, known as oncolytic viruses, might work after all. The data showed that an oncolytic virus developed...

It’s not easy to work with captive horseshoe bats, as Linfa Wang discovered. In 2005, the molecular virologist wanted to infect the animals with the virus that had caused the outbreak of severe acute respiratory syndrome (SARS) a few years earlier to find out whether it would evolve to grow well in the bats. Working in a maximum-biosecurity lab, he and his team at the Australian Animal...

In a trial beginning today in Maryland, a jury will consider whether the powerful Howard Hughes Medical Institute (HHMI) discriminated against a scientist by terminating her plum investigator award after she became disabled and asked for accommodations. Experts on disability rights say the trial will bring attention to an overlooked and pervasive form of discrimination in science. HHMI...

The carbon dioxide (CO 2 ) and methane (CH 4 ) that have such palpable effects on climate are frustratingly elusive. Even advanced satellites struggle to pinpoint plumes of the gases, which are the dominant drivers of global warming. Instead, countries assess their emissions by piecing together direct measurements, statistics on agriculture and fossil fuel...

When lightning ignited fires around California’s Big Basin Redwoods State Park north of Santa Cruz in August 2020, the blaze spread quickly. Redwoods naturally resist burning, but this time flames shot through the canopies of 100-meter-tall trees, incinerating the needles. “It was shocking,” says Drew Peltier, a tree ecophysiologist at Northern Arizona University. “It really...

Last week, a day after voters in the Netherlands delivered a surprise victory to far-right parties that have vowed to restrict immigration, Vinod Subramaniam, a nanoscientist and president of the board at the University of Twente, sent a letter to students and employees. “We are concerned about the effects of these results on higher education in general, and...

Since the Russian invasion of Ukraine began nearly 2 years ago, international observers have verified damage to hundreds of buildings , including museums and more than 150 churches. Now, a team of Ukrainian and U.S. archaeologists is surveying another category of destruction: damage to Ukraine’s archaeological heritage, much of which remains underground, often unexcavated...

Pitcher plants in the genus Nepenthes thrive in places where they shouldn’t. There’s very little nitrogen in the Southeast Asian and Australian soils where they grow—but they do just fine, thanks to a macabre source for this essential nutrient: the dissolved flesh of small animals, mostly insects, that slip into their bulbous traps. A new study suggests...

For sleepy humans, nodding off can be inconvenient—say, during a boring lecture—or even downright dangerous, such as while driving a car. But for Antarctica’s nesting chinstrap penguins ( Pygoscelis antarcticus ), these secondslong bits of shuteye known as “microsleeps” may help them survive. These mininaps net the birds about 11 hours of sleep per...

In the medicine of the future, molecular physicians built from a patient’s own cells might ferret out cancer, repair injured tissue, and even remove plaque from blood vessels. Researchers have now taken a step toward that vision: They’ve coaxed tracheal cells to form coordinated groups called organoids that can propel themselves with tiny appendages. When added to wounded neurons...

Maize is one of the world’s most important crops, but its origins have long bedeviled scientists. It took more than a century for scientists to settle on the idea that it was domesticated about 9000 years ago in the lowlands of Mexico from a wild grass: a subspecies of teosinte called parviglumis . But now, a team of geneticists has complicated that...

People who lived in central Siberia thousands of years ago enjoyed a comfortable lifestyle despite the area’s cold winters. They fished abundant pike and salmonids from the Amnya River and hunted migrating elk and reindeer with bone and stonetipped spears. To preserve their rich stores of fish oil and meat, they created elaborately decorated pottery. And they built the world’s...

Approach that effectively adds antacids to seawater could grow into a multibillion-dollar industry

LEADERSHIP Argentina’s president targets science The election last week of libertarian Javier Milei as Argentina’s next president has many of the nation’s scientists fearing the future. Milei, who won 55.7% of the vote, has vowed to close or dramatically restructure the National Scientific and Technical Research Council...

Last week, the World Health Organization (WHO) revealed that the Democratic Republic of the Congo (DRC) was experiencing its largest, most deadly outbreak of mpox ever, with more than 12,000 suspected cases so far this year and nearly 600 deaths, far surpassing those from the global outbreak of the same viral disease over the past 2 years. The WHO report and a study out today also explore...

One of the world’s largest databases of whole genomes has just become a lot larger. The British health study known as the UK Biobank today made the full genetic sequences of nearly 500,000 people available to scientists for analysis, more than doubling the size of an earlier data set. Combined with long-term health data on participants, this “treasure trove” has the potential to...

Cancer treatments that harness the immune system to fight the disease have revolutionized its care in recent years. One strategy, chimeric antigen receptor T cell, or CAR-T, therapy, is a personalized treatment that engineers a cancer patient’s own immune cells to target and destroy their malignant cells. Several such lifesaving treatments are on the market for blood cancers and...

Spain’s much-maligned system for evaluating scientists, in which the sole criterion for career advancement is the publication of papers, is set to be overhauled under new proposals from the country’s National Evaluation and Accreditation Agency (ANECA). The reforms, announced earlier this month, would for the first time see researchers at Spain’s public universities...

The materials cookbook has suddenly grown tens of times longer. Modern technologies, from electronics to airplanes, draw on just 20,000 inorganic materials, largely discovered through trial and error; scientists have predicted but not made tens of thousands more. This week, however, researchers report that with a new artificial intelligence (AI), they have predicted the ingredients and...

Astronomers have discovered a highly unusual planetary system around a nearby star. It holds six planets, all bigger than Earth but smaller than Neptune, a variety that is absent in our Solar System but common across the Milky Way. Moreover, all of the planets orbit in rhythmic harmony, which suggests the system has remained undisturbed since its formation billions of years ago. The...
