Phys.org / How the female baboon body has the final say in sperm selection
Just because a female olive baboon has mated with a specific male doesn't mean he will be the father of her offspring. According to a new study published in PLOS Biology, mate selection continues long after copulation as ...
Phys.org / Teachers tend to help the same kids repeatedly when using AI-powered tutoring tools
A new study finds teachers tend to provide assistance to similar subsets of students when using AI-powered educational tools, rather than touching base regularly with everyone in their classes. The findings could be used ...
Medical Xpress / A big step toward safe, reversible male contraception
Cornell scientists have taken a major step toward developing a safe, reversible, long-acting and 100% effective nonhormonal male contraceptive, considered the holy grail of male contraception. A proof-of-principle study in ...
Phys.org / Hot-dry extremes could hit 28% of humanity five times more often by end of century
In their current state, climate policies around the world could leave a significant chunk of the global population exposed to simultaneous extreme heat and drought over five times more often by the end of this century than ...
Tech Xplore / Latest Anthropic AI model finds cracks in software defenses
Anthropic on Tuesday said its yet-to-be-released artificial intelligence model called Claude Mythos has proven keenly adept at exposing software weaknesses.
Phys.org / Analysis finds geometric thinking may come from wandering, not a human-only math module
Debates over how geometry is understood and learned date back at least to the days of Plato, with more recent scholars concluding that only humans possess the foundations of this understanding. However, a new analysis by ...
Phys.org / Bird flu spread could be impacted by where waterfowl like to live
The movement patterns of waterfowl, including ducks, swans and geese, may affect the spread of highly pathogenic avian influenza in bird populations, according to a new study from the University of Georgia. The findings are ...
Phys.org / Rich biodiversity found in Japan's deepest ocean trenches, including an unidentified 'mystery' species
A new study published in the Biodiversity Data Journal provides a profound look at life up to nearly 10 kilometers below the ocean's surface in the Japan, Ryukyu, and Izu-Ogasawara trenches. The research catalogs at least ...
Phys.org / Parasitic tapeworm—a risk to domestic dogs and humans—found in Washington coyotes
New evidence suggests that a disease-causing tapeworm that has been spreading across the United States and Canada has arrived in the Pacific Northwest. The tapeworm, called Echinococcus multilocularis, lives as a parasite ...
Phys.org / Ranks of Disparity: New approach fixes flaw in fairness algorithms
As organizations increasingly rely on algorithms to rank candidates for jobs, university spots, and financial services, a new method, named hyperFA*IR, offers a more principled approach when picking candidates based on a ...
Phys.org / Social honey bees stay cool: How groups mitigate heat-triggered hormone spikes
Heat can change a honey bee's hormone levels, but only if the bee is alone. New research from MSU entomologist Zachary Huang shows that isolated honey bees experience a rapid hormonal rise when exposed to high temperatures, ...
Phys.org / Astronomers thought the early universe was full of hydrogen: Now they've found it
The Eberly Telescope Dark Energy Experiment (HETDEX) has discovered tens of thousands of gigantic hydrogen gas halos, called "Lyman-alpha nebulae," surrounding galaxies 10 billion to 12 billion years ago. Known as Cosmic ...
