'Stupendously large' primordial black holes ruled out as a dark matter source

Primordial black holes are hypothetical objects that could have formed directly from dense clumps of matter in the very early universe. If they exist, their dramatic origins would set them apart from the black holes we see today, which form when massive stars collapse. Some theor

Stronger flu shot linked to nearly 55% lower Alzheimer's risk

A surprising new study suggests that a stronger flu shot could offer older adults significantly greater protection against Alzheimer's disease. Researchers at UTHealth Houston analyzed nearly 200,000 adults ages 65 and older and found that those who received a high-dose influenza

Personalized savings reminders can help boost retirement savings

Private retirement savings are an increasingly important topic in public debate. One popular idea is to phrase savings reminders in one of two ways: either you emphasize what someone stands to lose if they don't save, or you emphasize what they stand to gain if they do. To date,

Disasters and debt. Escaping the 'climate-debt doom loop'

It took around 480,000 trucks to haul away 4.8 million metric tons (5.3 million tons) of rubble across western Jamaica after Hurricane Melissa tore through the Caribbean in 2025, United Nations satellites showed.

Atom-scale model could help improve material growth for advanced electronics

Penn State researchers have refined an atom-scale model of how silicon carbide changes from a solid into vapor during crystal growth, work that could help manufacturers produce higher-quality material for advanced electronics while reducing costly trial-and-error experiments.

World-first successful wild release of endangered broad-headed snake

The broad-headed snake (Hoplocephalus bungaroides), one of Australia's most endangered snakes, has been given a lifeline, with at least four of six captive-bred juveniles surviving the critical first few months after their release into the wild.

Why bandicoots and bilbies evolved such different snouts

Why does a quenda have a short, sturdy snout, while its relative the bilby has such a remarkably long one? New research led by Murdoch University's Harry Butler Institute suggests millions of years of adaptation to different environments across Australia and New Guinea may help e

A galaxy nicknamed Misty Moons offers a glimpse of early star formation

Gravitational lensing is one of astronomy's best tricks for seeing the early universe. When a massive galaxy cluster sits in between the observer and a distant object, its gravity bends and magnifies the distant object's light, acting like a giant natural magnifying glass. Galaxi

Game theory helps SETI search for alien civilizations

The search for extraterrestrial intelligence (SETI) is mostly concerned with where to look for technosignatures from another civilization. Between 2012 and 2015, SETI's Project Phoenix targeted about 1,000 sun-like stars for signs of intelligent life. But where to look might not

Chimp sanctuary delivers an ape's food by drone amid Florida floods

A Florida chimpanzee sanctuary had to deliver food to one of its 200 apes by drone this week because the property was swamped by heavy rain. But the animals stayed safe, and the water finally was receding significantly on Saturday, the organization said.

A nuclear blast could save Earth from an asteroid, but there's a catch

A nuclear explosion might save Earth from a deadly asteroid, but new research suggests that hitting the wrong side could make the difference between success and disaster. Scientists found that an asteroid's irregular shape can dramatically affect how it responds to an X-ray blast

Scientists discover hidden brain changes linked to common sleep disorders

Scientists have discovered that sleep disorders are associated with structural changes in brain regions that control attention, decision-making, and emotions, potentially explaining why disrupted sleep can affect everyday thinking and behavior. The findings, drawn from 57 brain i

Scientists squeeze record-breaking X-ray power into an incredibly tiny spot

Scientists have created record-breaking X-ray flashes lasting just 300 attoseconds, concentrating enormous power into an incredibly tiny spot. The breakthrough could unlock a new way to observe electrons in action and potentially control the ultrafast processes that drive chemica

Why the tropics lose the most birds when cities expand

Tropical ecosystems are famous for their teeming, exuberant diversity. In fact, the dramatic increase in biodiversity from the poles to the tropics—known as the latitudinal diversity gradient—is pervasive across branches of the tree of life, and fossil evidence suggests it has ex

Mysterious gas leaks suggest Mars may still be volcanically alive

Mysterious gas emissions and fresh volcanic fissures suggest that Mars may not be geologically dead after all, with hot magma potentially still active deep underground. The discovery could point to hidden pockets of warmth and chemical energy capable of supporting microbial life
