Phys.org / Camera captures first video of a red fox attacking a wolf pup
We are used to seeing a strict order in nature, with apex predators at the top feeding on those lower down the pecking order. But in video footage from a nature reserve in Italy, we see a red fox turning the tables, attacking ...
Medical Xpress / Cheek cells may provide clues to schizophrenia risk
A simple cheek swab could one day provide a quick and noninvasive diagnostic test for schizophrenia. A new study published in Science Advances has identified higher levels of two biological markers in the cheek swabs of patients ...
Phys.org / Many scientists now use AI but fail to disclose it, study finds
When scientists employ generative AI tools like ChatGPT to help with tasks such as editing and translation for their academic writing, many journals now ask them to disclose this assistance. The rules are intended to maintain ...
Phys.org / New species of ancient mollusk found in South Korean waters
Scientists have discovered a new species of chiton, an ancient marine mollusk that has remained virtually unchanged for the last 300 million years. Chitons have an elongated oval shape with a shell composed of eight interlocking ...
Phys.org / Scientists create a hexagonal diamond that could be even harder than the real thing
To misquote a famous song, "Diamonds are industry's best friend." Cubic diamond is the hardest mineral on Earth and is used in everything from precision cutting tools to high-performance semiconductors as well as expensive ...
Tech Xplore / How AI could end online anonymity
The internet is rife with anonymous accounts as users adopt pseudonyms, sometimes for genuine reasons like speaking freely, and other times for nefarious ones. But this era of online privacy could be coming to a close. In ...
Phys.org / Cockroaches that eat each other's wings become exclusive partners
Scientists have discovered that, far from being solitary insects, some cockroaches appear to form an exclusive bond with a partner. And how do they get this relationship off the ground? By eating each other's wings.
Tech Xplore / Bioinspired robot eye adjusts its pupil to handle harsh lighting
Robot vision could soon get a boost thanks to the development of a bioinspired eye that can automatically adjust its pupil size in response to changing light levels. Robots, self-driving cars and drones often struggle with ...
Phys.org / Left-handed people may have a psychological edge in competition
Left-handers are more competitive than right-handers, according to a new study published in the journal Scientific Reports. The findings may help explain why left-handedness has persisted throughout evolution despite the ...
Tech Xplore / AI often escalates to nuclear action in war games
There are some things perhaps we might not want artificial intelligence to handle, at least for the time being. When leading chatbots were put through war-game simulations, they opted for nuclear signaling or escalation in ...
Phys.org / Ancient Greek priestesses may have turned ergot fungus into a psychedelic brew during the Eleusinian Mysteries
The Eleusinian Mysteries were secret religious rites in ancient Greece honoring the goddess Demeter and her daughter Persephone, and aimed to remove the fear of death. The ceremonies included days of fasting, rituals and ...
Phys.org / The climate cost of staying cool: How AC could impact global warming by 2050
It is a double-edged sword. As the planet heats up, more of us are turning up and turning to air conditioning to keep us cool. The trouble is that, as well as consuming vast amounts of electricity, AC also leads to significant ...
Phys.org / Missing methane: Countries may be underestimating wastewater greenhouse gas emissions
The amount of greenhouse gases produced by the wastewater sector may be higher than reports suggest. According to a paper published in the journal Nature Climate Change, countries are missing out on reporting a significant ...
Medical Xpress / Ketamine reduces anxiety and social withdrawal in stressed adolescent mice
Ketamine is a powerful anesthetic used for surgery and acute pain management. But in recent years, it has also gained a reputation as a potential treatment for certain mental health conditions like stress and anxiety. In ...
Phys.org / Stale bread and bacteria could power a new era in green chemicals
Scientists have found a way to use common bacteria as tiny, green chemical factories to replace a process that currently relies on fossil fuels. In industrial hydrogenation, the hydrogen added to molecules to create products ...
