Crystals hint at a volcano's ability to erupt
University of Queensland researchers have shown tiny crystals are a window to activity inside volcanoes and could provide clues to when they might erupt.

'Burning': Life under the world's dirtiest skies
On the outskirts of India's capital, a short motorbike ride through the urban area with the world's worst air pollution leaves salesman Kanwar Singh coated in toxic dust.
Despite sacrificing people after catastrophic El Niño flooding, ancient societies were generally peaceful
To understand how societies might react to climate change, archaeologists look at social responses to extreme climate events in the past—and in some places, that included measures as drastic as human sacrifice. Mass ritual sacrifices along the desert coast of northern Peru have
A little-known protein could be a major culprit in type 2 diabetes
Scientists have discovered that a buildup of a protein called Miro1 may be a hidden driver of insulin resistance in Type 2 diabetes, with preclinical experiments showing that removing it restores the muscles’ response to insulin. Exercise was also found to lower Miro1 levels in
A new clinical simulation model strengthens the empowerment and autonomy of nursing staff
To date, many of the methods used in clinical simulation have focused primarily on assessing technical skills and compliance with medical standards, often from a generic, interprofessional perspective. Although technical skills are essential, this approach overlooked key
Hidden climate superpower: Why some ocean “snow” carries six times more carbon
Scientists have discovered that the stickiness of underwater “marine snow” plays a surprisingly important role in how much carbon reaches the deep ocean. Gooier particles resist bacterial breakdown and can transport more than six times as much carbon to the depths, revealing an
Radiocarbon analysis uncovers possible traces of hidden earthquakes off Japan's coast
Researchers at the University of Tokyo have used a new type of radiocarbon analysis to study a sediment core taken from the Kumano Sea off the coast of Japan. This has revealed multiple "hidden" traces of previously unknown earthquakes in the Nankai Trough, where the country's
Small histone differences help shape gene regulation during sperm development
Researchers from Kyushu University have found that H3mm15, a histone H3.3 subvariant, contributes to normal sperm development in mice by helping regulate gene expression during spermatogenesis. The findings show that H3mm15 cannot be interchanged with conventional H3.3;
Scientists discover stunning new Amazon fish that may already be endangered
Researchers have discovered a stunning new species of tiny orange-patterned fish in the Brazilian Amazon, but its survival may already be at risk. Named Laimosemion laranja, the brilliantly colored killifish measures less than three centimeters long and was found in just three
Scientists wipe out deadly brain tumors in every mouse tested with new cancer therapy
Scientists at UC San Francisco have developed a powerful new cancer therapy that remains inactive until it reaches the brain, where it switches on to attack deadly tumors. The engineered immune cells, called B-SYNC CAR-T cells, completely eliminated diffuse midline glioma
An ancient ocean full of giant predators reveals a surprising twist in evolution
A remarkable fossil discovery in Colombia is challenging how scientists understand major evolutionary changes in Earth's history. Researchers uncovered an incredibly diverse ancient marine ecosystem where giant reptiles, sharks, and other creatures thrived as older evolutionary
Einstein's equations reveal how gravity could break, reconnect, and release energy
More than a century after Einstein revolutionized our understanding of gravity, scientists have uncovered a surprising new phenomenon hidden within his equations. Researchers at Columbia University and Universidad Adolfo Ibáñez have identified a theoretical process called
Liquid-assisted crystal growth cuts perovskite defects for efficient solar cells and LEDs
A research team led by professor Seong Sik Shin of the SKKU Advanced Institute of Nanotechnology (SAINT) at Sungkyunkwan University (SKKU), in international collaboration with the Korea Research Institute of Chemical Technology (KRICT), the University of California, San Diego,
JWST tracks more than 100 magnified stellar events in the Dragon galaxy
Using the James Webb Space Telescope (JWST), a team of astronomers identified 104 magnified stellar events in a galaxy known as the Dragon, located around 6.5 billion light-years away. This discovery more than doubles the previous record of 44 such detections in the same
How space weather powers auroras in the sky and threatens power grids on the ground
An aurora is one of nature's most spectacular light shows: It looks like green or red curtains rippling across the night sky. When viewed from the ground, this colorful display might seem far away and disconnected from anything happening on Earth's surface.
100 buses long: Scientists map one of the world's largest known coral colonies
A huge coral colony stretching more than 1.5 kilometers (0.93 miles) along the outer reef of the Cocos (Keeling) Islands has been identified by researchers, making it one of the largest known coral colonies ever recorded.
New species of ground-dwelling bird, the largest of its kind, identified in same cave as Homo floresiensis
In 2009, researchers working in the Liang Bua cave on Flores Island came across a leg bone. The 190,000–120,000-year-old fossil was identified as a bird bone and set aside. Like many bird bones before it, it was overlooked and left to collect dust.
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
'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
Why do some people hear pitch better than others? Internal noise may be the key
The less internal noise you have, the more reliably you can tell similar sounds apart
Acorns—not deer—can predict a rise in Lyme-spreading ticks
Despite deer’s essential role in tick reproduction, looking to acorn numbers instead can forecast Lyme disease booms almost two years in advance
Want to fly to the moon? NASA is looking for new astronauts to help grow its Artemis program
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.
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.
