Phys.org / Chimps' love for crystals could help us understand our own ancestors' fascination with these stones
Crystals have repeatedly been found at archaeological sites alongside Homo remains. Evidence shows that hominins have been collecting these stones for as long as 780,000 years. Yet, we know that our ancestors did not use ...
Medical Xpress / Using digital cognitive assessments for dementia diagnosis: Are primary care providers ready?
A Gerontological Society of America (GSA) report summarizes survey findings on the readiness of the primary care workforce to adopt digital cognitive assessments (DCAs) for use in the diagnostic process for cognitive impairment ...
Phys.org / The Black Death's counterintuitive effect: As human numbers fell, so did plant diversity
Between 1347 and 1353, Europe was gripped by the most catastrophic pandemic in its history: the Black Death. Killing many millions, the plague wiped out between one-third and a half of Europe's population.
Phys.org / Toward practical laser-driven light sails using photonic crystals
Most space missions rely on chemical rockets for propulsion. Rockets must carry fuel, which increases spacecraft mass and limits their speed and travel distance. For decades, researchers have explored light sails as an alternative. ...
Phys.org / Carbon emissions now more than double the planetary boundary, analysis finds
Earth is not infinite. Pollution beyond certain levels threatens the climate and ecosystems. To prevent this, scientists have proposed planetary boundaries, defining the safe operating limits of the Earth system. A KAIST ...
Phys.org / Almost a third of Gen Z men agree a wife should obey her husband, global study finds
Some 31% of Gen Z men agree that a wife should always obey her husband and one third (33%) say a husband should have the final word on important decisions, according to a new global study of 23,000 people. Gen Z men (born ...
Phys.org / Missing technosignatures? Turbulent plasma may blur ultra-narrow signals before they leave their home star systems
A new study by researchers at the SETI Institute suggests that stellar "space weather" could make radio signals from extraterrestrial intelligence harder to detect. Stellar activity and plasma turbulence near a transmitting ...
Phys.org / How to live a long and healthy life, according to the ancients
Just like in the modern world, people in ancient times wanted to know how to live a long and healthy life.
Phys.org / Satellite images uncover new threat to emperor penguins during their annual molt
The tall black-and-white residents of Antarctica, who waddle around its icy landscape, are in peril thanks to the rapidly warming global climate. Emperor penguins go through an annual transformation called catastrophic molting, ...
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 / 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 / Dense, dark forests in Europe are a modern phenomenon
For over 20 million years, the landscape of Europe has been a tree-rich mosaic of grasslands, scrubs and more or less open woodlands with an abundance of wildflowers. This is the conclusion of a new and comprehensive study ...
