Phys.org / Earliest Americans specialized in megafauna hunting from Alaska to South America, analysis of 50 sites reveals
New research led by a University of Alaska Fairbanks archaeologist reveals that the earliest Native Americans had highly specialized diets, primarily hunting the largest animals on the landscape, and they targeted these megafauna ...
Phys.org / Brown leaves before fall could signal lasting heat damage, researchers warn
Due to increasing heat and drought, forests are turning brown more often before autumn, when leaf senescence normally occurs. It is often unclear whether the trees are actively shedding foliage to avoid a breakdown in water ...
Phys.org / How generative AI and physics can help design new antibiotics
By 2050, scientists estimate that antibiotic-resistant infections will be associated with more than 8 million deaths around the world every year.
Phys.org / Off-center stellar death points to wandering supermassive black hole stripped of its own galaxy
Astronomers have uncovered new details about the black hole that ripped apart a star in a tidal disruption event named AT2024tvd. Findings suggest it is a wandering supermassive black hole—the kind that is not located at ...
Phys.org / New biosensor reveals rare lipid gathers in membrane hotspots during cell stress
Inside every cell are lipid molecules that make up cellular membranes, helping organelles communicate and respond to stress. Researchers have struggled to observe lipids in action because current detection tools lack sufficient ...
Phys.org / Prescribed burns may generate over 20% of fine particle pollution in southeastern US
Prescribed fires are vital for reducing wildfire risk and sustaining forest biodiversity. But they also contribute significantly to air pollution and smoke exposure, according to new research from the University of Georgia. ...
Science X / Built-in 'antenna' may help cells sense a healing spark to guide repair after injury
When skin is wounded, it doesn't just send out chemical distress signals; it also generates a subtle electrical field. This "electric beacon" forms as the usual voltage across the tissue collapses, creating a guiding current ...
Phys.org / Conservation genomics faces growing calls to center Indigenous knowledge and data rights
Throughout human ecological history, we have played a variety of roles within ecosystems around the world. In this so-called Anthropocene era, genomic innovations have given us new and powerful ways to influence the environment ...
Phys.org / A WRAP for biology's greasiest problem
Embedded in the boundary between the inside and outside of each cell are membrane proteins. They act as first responders by sensing signals, regulating which molecules enter and leave the cell, and enabling cells to quickly ...
Phys.org / Italy displays paintings from an ancient Etruscan tomb, its latest cultural acquisition
Italy on Tuesday put on display one of the best known examples of Etruscan painting, panels from a tomb that it acquired for 15 million euros ($17 million) in the Culture Ministry's buying spree of big-ticket pieces of the ...
Phys.org / Compromise drives shared risky decisions, but biased blame and credit can break teamwork
Relationships are all about compromise. From deciding on where to eat dinner with a friend to negotiating chore lists at home, we often experience situations that require some flexibility. But what happens when we must work ...
Medical Xpress / Precision fMRI maps prefrontal cortex in individuals, revealing fine-scale structures
Much like camera settings—filters, flashes and focus—affect what we notice in a final photo, the way scientists measure something can affect how we interpret and understand it. This is especially true when imaging things ...
