In a move that has rattled some in the biomedical research community, the U.S. House of Representatives last night approved a ban on federal funding for “gain-of-function” research that modifies risky pathogens in ways that can make them more harmful to people. Scientific groups say the vaguely worded provision could unintentionally halt a large swath of studies, from flu vaccine...

Surprise $200 million bequest has tiny Summer Science Program thinking big
As climate-friendly fuels, hydrogen (H
) and ammonia (NH
) are enticing. Because they lack carbon, they can be burned to produce nothing but environmentally benign water and nitrogen (N
). But if producers do not take care to prevent leaks or incomplete combustion, researchers are now warning, the fuels could generate pollutants that...

Australia’s top science agency faces scrutiny over industry influence
More than 3000 years ago during the Bronze Age, people across Eurasia formed massive trade networks that tied the continent together. But the Pannonian Plain, an open expanse that today includes parts of Romania, Hungary, and Serbia, was considered a relative hinterland. That was true even after archaeologists 2 decades ago uncovered a handful of massive Bronze Age enclosures, some...

New feline coronavirus blamed for thousands of cat deaths in Cyprus
Australia’s leading research agency is facing questions about possible ethical lapses after a U.S. law firm released documents suggesting some of its scientists did not disclose that they had allowed oil giant BP to review studies prior to publication in a journal or presentation at a conference.
“It’s a mystery why BP’s legal team would be reviewing independent...

AI churns out lightning-fast forecasts as good as the weather agencies’
When thousands of cats started to die this year on the Mediterranean island of Cyprus, nicknamed the “island of cats” for its 1-million-strong feline population, the crisis made international news. The animals had fevers, swollen bellies, and lethargy—symptoms that pointed to feline infectious peritonitis (FIP), a common condition caused by a type of cat coronavirus. But scientists...

Cosmic blast seared Earth’s atmosphere from 2 billion light-years away
Meteorologists call it the “

Rarely do severe storms or heat waves catch people unaware. This revolution has saved lives and money, but it also comes with a cost: billions of dollars’ worth of energy-hungry...

On 9 October 2022, for 7 minutes, high energy photons from a gigantic explosion 1.9 billion light-years away toasted one side of Earth as never before observed. The event, called a gamma ray burst (GRB), was 70 times brighter than the previous record holder. But what astronomers dub the “BOAT”—the brightest of all time—did more than provide a light show spanning the...

Misconduct concerns, possible drug risks should stop major stroke trial, whistleblowers say
If a bite of dandelion greens or extra-dark chocolate makes you pucker, there’s good reason. Bitterness can indicate the presence of toxins in potential foods, and animals long ago honed the ability to ferret out harsh tastes.
But the ability to sense bitterness may be even older than many presumed, a new study finds. It likely first evolved in vertebrates roughly 460 million...

Huge variety of eye colors in today’s cats may trace back to distant ancestor’s unusual peepers
The restoration and protection of forests worldwide could help remove about 226 gigatons of carbon from the atmosphere, according to a study published today in
. That’s equivalent to roughly 20 years of emissions from burning fossil fuels and other sources at current rates. Some experts say the analysis provides a more reliable estimate of the carbon-capturing...

Despite sexual harassment shadow, biologist David Sabatini lands job at top Czech institute
If you get lost in the luminous orange peepers of housecats or the baby blues of white tigers, thank the granddaddy of all felines—an ocelotlike creature that lived more than 30 million years ago. A new study finds that this distant ancestor of lions, tigers, and housecats sported brown and gray eyes, the latter of which allowed its descendants to evolve a veritable rainbow of iris...

David Sabatini, the high-flying biologist who lost positions at three prominent U.S. institutions after breaching sexual misconduct policies, last month began a new job as a senior scientist at the Institute for Organic Chemistry and Biochemistry Prague (IOCB), a powerful arm of the Czech Academy of Sciences. The hire has divided Czech scientists and is likely to ignite debate about...

Base editing, a new form of gene therapy, sharply lowers bad cholesterol in clinical trial
- 23/11/12 21:30
A technique for precisely rewriting the genetic code directly in the body has slashed “bad” cholesterol levels—possibly for life—in three people prone to dangerously high levels of the artery-clogging fat. The feat relied on a blood infusion of a so-called base editor, designed to disable a liver protein, PCSK9, that regulates cholesterol.
“It is a breakthrough to have...

Preregistering, transparency, and large samples boost psychology studies’ replication rate to nearly 90%
News at a glance: Fish family tree, AI safety research, and open access’ next steps
For the past decade, psychology has been in the midst of a replication crisis. Large, high-profile studies have found that only about half of the findings from behavioral science literature can be replicated—a discovery that has cast a long shadow over psychological science, but that has also spurred advocates to push for improved research methods that boost rigor.
Now, one of...

Is social media addictive? ‘Digital detox’ study suggests not
Lice DNA records the moment Europeans colonized the Americas
A week of reduced social media usage neither increased nor decreased people’s desire to get back online, a new study finds. The lack of craving to return to social media platforms such as Instagram and X (formerly Twitter) suggests that for most people, the use of social media may not be truly addictive, the authors argue. Some experts remain skeptical, however.

New antifungal kills without toxic side effects
The U.S. Census Bureau may soon change the way one of its nationwide surveys asks about disability. But alarm bells are ringing for many researchers and activists, because the proposed change would dramatically decrease the official number of people in the United States who are considered disabled.
“Disabled people are already underserved,” says Scott Landes, a sociologist at...
The antifungal Amphotericin B (AmB) is an old and effective drug—it saved many COVID-19 patients whose compromised immune systems failed to stop secondary fungal infections. But it sometimes causes life-threatening kidney damage. Now, after more than a decade of sleuthing into this toxicity, researchers have not only found an explanation, but used it and a robotic “chemist” to...
