Phys.org / Early hardship may shape how oxytocin influences altruism
While humans are inherently social beings, they can interact and connect with others in very different ways. For instance, while some people tend to be more altruistic, others are less prone to helping their friends, acquaintances ...
Phys.org / Amber fossil reveals firefly relative with unprecedented antennae
Insects rely on a wide range of strategies to sense their surroundings and communicate with their peers. Fireflies (Lampyridae) and some related beetles are known for their ability to produce visible light through chemical ...
Medical Xpress / Tsimané and Moseten peoples of lowland Bolivia demonstrate an intriguing case of epidemiological resilience
Despite widespread COVID-19 infection in the Tsimané and Moseten populations of Bolivia, the mortality rate in these remote Indigenous groups was the lowest ever recorded for any population or region.
Phys.org / Copper's surprising melting behavior provides insights into future fusion design
Future fusion power plants aim to recreate the heart of a star here on Earth to power our future energy needs. While the core fusion plasma will burn at hundreds of millions of degrees, the surrounding structural components ...
Tech Xplore / Engineers connect bacteria to create living transistors
MIT researchers have engineered bacteria that can function as transistors, allowing the team to create living "circuit boards" that can be printed onto a growth medium in a Petri dish.
Medical Xpress / States enact emergency orders on kratom while awaiting federal rules
States are moving faster and further than federal regulators to get kratom off store shelves, with some banning the herb outright while a pending federal rule targets only one of its chemicals.
Phys.org / Gold nanoclusters could help break down Alzheimer's amyloid plaques
Alzheimer's disease is a neurodegenerative brain disorder characterized by progressive memory loss and a decline in other mental functions. Past studies have consistently linked this disorder to the accumulation of the protein ...
Phys.org / Ancient Egyptian tomb shows how burial trends changed over hundreds of years
The Theban Necropolis, opposite Luxor, consists of more than 400 tombs. In a new Frontiers in Environmental Archaeology study, researchers in Spain examined part of one of these tombs—chamber three in tomb TT 209—to reconstruct ...
Phys.org / Immune cells have a 'sense of touch,' scientists discover
Scientists have long believed that tissue-resident memory T cells—which remain in tissues after an infection has cleared and respond rapidly if the threat returns—are shaped primarily by biochemical signals. A McGill University–led ...
Phys.org / Gene-edited beagles produce no detectable major dog allergen, early tests find
Humans love dogs, but petting them can leave some people sneezing and wheezing. About 15% of the world's population lives with a dog allergy, which can increase the risk of hay fever and asthma. The main culprit is Can f ...
Phys.org / Last common ancestor of humans and chimpanzees could have been a vertical climber, no matter its feet
New research suggests that no matter what we eventually determine the last common ancestor of humans and chimpanzees to be, we'll learn it was a primate that climbed trees.
Phys.org / Three photons at once beat the standard photon test
Physicists at the University of Twente have improved the standard test for the quality of individual particles of light. By letting three photons interfere at the same time instead of two, they draw more information from ...
