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
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;
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,
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
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.
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.
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.
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
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
The less internal noise you have, the more reliably you can tell similar sounds apart
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 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.
Scientists have discovered that fasting for just 24 hours increases a beneficial gut bacterium that helps the intestines regenerate after radiation damage. The preclinical findings could pave the way for new treatments that protect healthy tissue during cancer therapy,
MIT scientists have developed nanoparticles that reprogram immune cells directly inside the body to attack cancer and harmful immune cells, eliminating tumors and reversing liver damage in mouse experiments. The breakthrough could make powerful immune therapies dramatically
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
A major international study tracking more than 26,000 men found that very low testosterone levels were associated with an 18% higher risk of dying from cancer later in life. Surprisingly, testosterone itself showed no clear link to prostate cancer, although two other sex
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
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
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
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
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
A study of more than 17,700 US adults found that people who use cannabis in multiple forms have dramatically higher rates of daily consumption and addiction symptoms than those who stick primarily to one method. Nearly 67% of those who used almost every form met criteria for
