Phys.org / Asteroid that wiped out dinosaurs had limited impact on sharks and rays, study shows
A new study using advanced artificial intelligence (AI) has revealed that the asteroid strike that wiped out the dinosaurs 66 million years ago caused only a modest decline in shark and ray species. The findings, published ...
Phys.org / Changes to cougar diets and behaviors reduce their competition with wolves in Yellowstone, study finds
A new study shows that interactions between wolves and cougars in Yellowstone National Park are driven by wolves stealing prey killed by cougars and that shifts in cougar diets to smaller prey help them avoid wolf encounters. ...
Phys.org / Essential oils may provide a natural remedy for antibiotic resistance
Thyme, rosemary, and lavender have long been associated with natural medicine. Today, however, these aromatic plants are increasingly being studied by researchers. "In an era of ever-increasing microbial resistance to antibiotics, ...
Phys.org / A possible ice-cold Earth discovered in the archives of the retired Kepler Space Telescope
Scientists continue to mine data gathered by NASA's Kepler Space Telescope, retired in 2018, and continue to turn up surprises. A new paper reveals the latest: a possible rocky planet slightly larger than Earth, orbiting ...
Medical Xpress / Fecal transplant capsules show promising results in clinical trials for multiple types of cancer
Fecal microbiota transplants (FMT) can dramatically improve cancer treatment, suggest two groundbreaking studies published in the Nature Medicine journal. The first study shows that the toxic side effects of drugs to treat ...
Phys.org / From stellar engines to Dyson bubbles, alien megastructures could hold themselves together under the right conditions
New theoretical models have strengthened the case that immense, energy-harvesting structures orbiting their host stars could exist in principle in distant stellar systems. With the right engineering precautions, calculations ...
Phys.org / Amazon Leo satellites exceed brightness limits, study finds
Seeing a satellite zip across the night sky can be a fascinating sight. However, what may be spectacular for people on the ground is becoming a major problem for astronomers. A new study published on the arXiv preprint server ...
Phys.org / Massive runaway stars in the Milky Way: Observational study explores origins and ejection process
Researchers from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC), in collaboration with the Institute of Astrophysics of the Canary Islands (IAC), ...
Phys.org / The Great Mongolian Road: Japanese Imperial Army maps reveal first detailed documentation
In a study published in the Journal of Historical Geography, researchers Dr. Chris McCarthy and his colleagues have documented, for the first time, the Great Mongolian Road, a major yet understudied east-west caravan route ...
Phys.org / Surprising green ice on Lake Lipno: Cyanobacteria bloom in mid-winter
An unusual natural phenomenon appeared on Lake Lipno in South Bohemia, the Czech Republic, at the end of 2025. Large amounts of accumulated cyanobacteria in the water caused the ice to turn green. The phenomenon was thoroughly ...
Medical Xpress / These two viruses may become the next public health threats, scientists say
Two emerging pathogens with animal origins—influenza D virus and canine coronavirus—have so far been quietly flying under the radar, but researchers warn conditions are ripe for the viruses to spread more widely among ...
Phys.org / Spider monkeys pool their knowledge to find the best fruit
When spider monkeys want to tell others about the best fruit trees in the forest or ones they've missed, they do so by changing their social groups to share what they know, according to a new study published in the journal ...
