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
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
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,
Panda lovers are expected to line up Friday at Zoo Atlanta to see a new pair of giant pandas make their public debut.
Disasters and debt. Escaping the 'climate-debt doom loop' and more — today's news signal.
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.
For the first time, an international team of researchers from Germany, Thailand, India, China and the United States has created a three-component Hubbard system with tunable interactions in the laboratory. In doing so, the team used a quantum gas microscope to make the individual
A new study has found that a self-reinforcing interaction between temperature, soil moisture and atmospheric pressure is being triggered at high temperatures, making extreme heat waves 10% hotter than they would otherwise be. The study was published in Science Advances and led by
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.
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 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
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
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
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
Want to fly to the moon and help build a permanent lunar base? NASA is accepting applications for a new astronaut class that will help grow the Artemis program.
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 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 investigating a 2,800-year-old Siberian tomb discovered roughly 1,000 cannabis seeds and chemical evidence suggesting ancient Scythians used the plant for its intoxicating effects. The remarkable find, surrounded by evidence of elaborate burial rituals and animal sacri
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 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
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
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 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
Scientists have discovered a surprising quantum limit that prevents electrons from being tracked with unlimited precision in both space and time. The breakthrough could pave the way for manipulating chemical reactions and developing electronics hundreds of thousands of times fast
