NASA’s x-ray telescope faces a long goodbye

The end is nigh for NASA’s nearly 25-year-old Chandra X-ray Observatory. Funding for the space telescope was slashed last week in President Joe Biden’s budget request, which calls for winding the mission down over several years. Astronomers are up in arms over the announcement. They argue that the telescope is as productive as ever and remains a cornerstone of U.S....

West Virginia opens the door to teaching intelligent design

In 2005, then–U.S. District Court Judge John Jones ruled that intelligent design (ID)—the idea that life is too complex to have evolved without nudging from supernatural forces—cannot be taught in public school biology courses because it is not a scientific theory. This month, the West Virginia legislature found a workaround, and passed a bill that doesn’t name ID but will...

Mystery illness among U.S. diplomats did not cause permanent brain damage

For several years, dozens of U.S. diplomats and intelligence agents have fallen ill with a perplexing array of symptoms that some politicians, intelligence analysts, and physicians have speculated may have been triggered by a so-called directed-energy weapon. Whatever caused these anomalous health incidents (AHIs), as the cases have been labeled by the U.S. government, it did not leave...

‘Lab-leak’ proponents at Rutgers accused of defaming and intimidating COVID-19 origin researchers

Fraudsters. Liars. Perjurers. Felons. Grifters. Stooges. Imbeciles. Murderers. When it comes to describing scientists whose peer-reviewed studies suggest the COVID-19 virus made a natural jump from animals to humans, molecular biologist Richard Ebright and microbiologist Bryce Nickels have used some very harsh language. On X (formerly Twitter), where the two scientists from Rutgers...

A treaty to prepare the world for the next pandemic hangs in the balance

“Me first”—that’s how Tedros Adhanom Ghebreyesus, head of the World Health Organization (WHO), described the wealthy world’s response to the COVID-19 pandemic when he kicked off negotiations for a global “pandemic treaty” in December 2021. Even before vaccines had proved safe and effective, rich countries had purchased enough doses to cover their entire population several...

Department of Energy’s science chief announces her unexpected departure

After 22 months on the job, Asmeret Asefaw Berhe, director of the Department of Energy’s (DOE’s) Office of Science, is stepping down. Yesterday Berhe sent a letter to the office’s 815 employees saying her last day would be 28 March. With a budget of $8.2 billion, the office is the United States’s single largest funder of the physical sciences. Berhe, who was born in...

Honesty researcher committed research misconduct, according to newly unsealed Harvard report

Honesty researcher Francesca Gino “committed research misconduct intentionally, knowingly, or recklessly,” according to an investigation completed last year by the Harvard Business School(HBS) that was publicly released this week as part of Gino’s ongoing lawsuit against the university. On Tuesday, despite objections from Gino, a judge granted Harvard’s motion to unseal...

Watch out! This colorful bird raises a nest of cannibals

It might seem wasteful, but many birds lay more eggs than will successfully hatch. Scientists have long believed these extra eggs represent a form of insurance, ensuring that at least some offspring ultimately leave the nest. But for the Eurasian hoopoe—known for its showy orange crest and the whooping cry that gives the bird its name—a new study suggests these extra eggs exist for a...

Analysis: How NSF’s budget got hammered

Two summers ago, officials at the National Science Foundation (NSF) had good reason to anticipate years of healthy budget increases for the basic research agency. In August 2022, President Joe Biden had signed the CHIPS and Science Act, landmark legislation to revive the U.S. semiconductor industry that included a promise to more than double NSF’s budget, to $18.9 billion, by...

‘Cold blob’ of Arctic meltwater may be causing European heat waves

Global warming disrupts weather in many ways, but Europe’s string of record-breaking hot and dry summers has defied an easy link to climate change. Climate models do show Europe warming faster than the rest of the planet , but the recent scorchers were triggered by peculiar weather conditions: masses of hot, dry air parked over the continent , blocking...

We ‘baby talk’ our dogs. So why don’t we ‘baby face’ them?

“Who’s so cute? Yes you are. You are so cute!” Baby talk sounds pretty similar, whether we’re cooing to our infants or our dogs. We pitch our voices high and use many of the same phrases. But a new study has spotted a crucial difference: When baby talking our tots, our faces tend to be overly expressive—wide-open eyes, high eyebrows, and exaggerated smiles. With...

On its third try, Starship rocket flies through space but fails during re-entry

An hour after sunrise this morning, a roaring steel titan more than 120 meters tall ascended from South Texas over the Gulf of Mexico: SpaceX’s Starship, the largest and most powerful rocket ever built. This launch, the rocket’s third full test flight, wasn’t perfect and ended with Starship’s upper stage breaking apart during re-entry into Earth’s atmosphere. However,...

Some of our key gut microbes likely came from cows—and we’re losing them

Even strict vegetarians need a little help digesting plants. Although enzymes within the human mouth, stomach, and intestines can break down the simple carbohydrates found in candy and potatoes, they cannot on their own dissolve cellulose, the key component of plant cell walls. Instead, people rely on cellulose-chomping bacteria in their guts to do the dirty work. Our species may have...

Sensor protein explains how mice—and maybe people—know it’s cold

People wear gloves when making a snowman for a reason: Handling cold stuff can hurt. A new mouse study reveals what may be a key player in this response: a protein already known to enable sensory neurons in worms to detect cold . New evidence published this week in Nature Neuroscience confirms that this protein has the same...
