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...

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

ALS drug comes up short in trial
In a major setback for people suffering from amyotrophic lateral sclerosis (ALS), a drug approved in the United States and Canada in 2022 for the debilitating condition has failed in a 664-patient clinical trial, its maker, Amylyx Pharmaceuticals, said last week. Regulators...
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.

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

NASA’s Mars rover probes ancient shorelines for signs of life
THE WOODLANDS, TEXAS—
After a few years of hard labor on Mars, you could excuse the Perseverance rover for taking a trip to the beach.
For the past few months, NASA’s rover, which is collecting rock samples to eventually send to Earth, has explored a ring of rocks just inside the rim of Jezero crater, which is thought to have been filled with water billions...
Should doctors screen all kids for type 1 diabetes?
Millions worldwide live with type 1 diabetes, and for most the diagnosis came as a shock, following mysterious symptoms such as thirst and weight loss. But diabetes specialists have long known that certain blood tests can foretell the disease years earlier. That has left the field wrestling with a difficult question: Should healthy children get these blood tests, and would knowing about...
‘Smart’ fiber-optic cables on the sea floor will detect earthquakes, tsunamis, and global warming
Everybody in Portugal knows the date: 1 November 1755. It was All Saints’ Day, with candles lit in homes to honor ancestors. Then the earthquake struck, cracking the streets of Lisbon open and sparking a firestorm. A tsunami engulfed the port, and tens of thousands died. Even now people are aware of the threat— from a nearby seafloor junction where the grinding tectonic plates of...
Toothed whales—like humans—may go through menopause. And it may help them live longer
Ninety million years of evolution may separate toothed whales from humans, but we may share with them a rare reproductive strategy that allows relatively long life spans.
Toothed whales—including belugas, killer whales, and narwhals—can live into their 90s. Humans can live to 100 and beyond. Menopause may be part of the reason for that longevity, the researchers behind a...

Ladybug becomes powerful foe after ‘stealing’ toxins from invasive insect
In a thicket of prickly pear cacti near Valencia, Spain, a troop of predatory ants moves in for the kill. But their target—the white, shaggy-coated larva of a ladybug known as the mealybug ladybird (
Cryptolaemus montrouzieri
)—is far from defenseless. As the ants mount their attack, the juvenile beetle tenses its muscles and expels a drop of bright red fluid. Called...
Jupiter’s ocean moon may be dead inside
THE WOODLANDS, TEXAS—
With a saltwater ocean hiding under an icy shell, Jupiter’s moon Europa is one of the most promising places in the Solar System to look for life. Later this year, NASA will launch a $5 billion mission, Europa Clipper, to study the ocean and perhaps even sample it—assuming the moon ejects plumes of water through cracks in the ice, as some research...

‘Damning’ FDA inspection report undermines positive trial results of possible Alzheimer’s drug
In September 2022, Food and Drug Administration (FDA) officials arrived at an imposing, glass-dominated research complex at the City University of New York (CUNY). They planned to review records and practices in a lab run by pharmacologist Hoau-Yan Wang, who had been involved in clinical tests for an experimental Alzheimer’s drug. Two years earlier Wang and his colleagues had analyzed...
Amazing diversity of today’s ants tied to rise of flowering plants
As spring’s first buds emerge in the Northern Hemisphere, there’s fresh evidence of the evolutionary importance of angiosperms, better known as flowering plants. Their rise some 150 million years ago, a study concludes, powered the amazing diversification and spread of ants, helping more recent ant species survive, while changing conditions drove earlier forms to extinction. The...
Congress is using more science, but the two parties rarely cite the same studies
Researchers often criticize U.S. lawmakers for ignoring scientific evidence when it comes to writing legislation aimed at challenges such as climate change, gun violence, and access to health care. But members of Congress and their staffers are consuming plenty of research, judging by the number of citations to technical papers found in committee documents over the past few decades, a...
