Phys.org / Seabirds trade their own survival to raise more chicks after energy-intensive breeding seasons
Wild seabirds that face high energy demands during the breeding season go on to migrate farther and raise more chicks the next year, but at a cost to their own survival. An international team led by researchers from Nagoya ...
Phys.org / Prolonged stretching reorganizes tissue scaffolds and uncages cell nuclei
How do tissues cope with being stretched for hours or even days? A study led by researchers at the Institute for Bioengineering of Catalonia (IBEC) has uncovered an unexpected answer: Cells radically reorganize their internal ...
Phys.org / Kids who own cellphones have poorer reading comprehension scores than those who don't, researchers find
School cellphone bans might seem like a good way to improve learning for elementary school children, but new research published in Behavioral Sciences shows that simply owning a cellphone correlates with worse reading comprehension. ...
Phys.org / Hubble shows star formation in Andromeda galaxy is winding down
A new study using data from NASA's Hubble Space Telescope finds that star formation in the nearby Andromeda galaxy has undergone a 500-million-year decline, with an even steeper drop in the last 40 million years. Andromeda, ...
Phys.org / Molecular switch that activates cell growth signaling may offer more precise route for anticancer therapy
Cells carry their own growth switches. When enough nutrients—amino acids in particular—are available, cells flip this switch on and begin to grow. Researchers at KAIST and Yonsei University have uncovered the molecular mechanism ...
Phys.org / Astronomers identify one of the universe's rarest black hole events
A team of astronomers at the University of North Carolina at Chapel Hill has observed an extremely rare "wandering" black hole located tens of thousands of light-years from the center of its galaxy. This finding could reshape ...
Medical Xpress / Scientists decipher how T cells sense enemies—such as cancer—at point of contact
Every encounter between a T cell and a potential target—especially when that target is a developing tumor—begins with a rapid series of molecular decisions. Within seconds, the immune cell must determine whether to launch ...
Medical Xpress / Silver diamine fluoride treatment could halt cavities without shots, drilling or sedation
Every year, untreated tooth decay sends thousands of young U.S. children to emergency departments for dental problems doctors can't treat. Many eventually undergo surgery under general anesthesia, while others endure pain ...
Phys.org / Thin films 'dance' with substrates that are no longer inert, opening path toward 3D chips
Many of today's electronic devices—from the semiconductors in your cell phone to the photovoltaic cells in your solar panels—are built on thin-film substrates. The thin film is an electrically conductive material, while the ...
Phys.org / How invasive rats rewire coral reef food webs to create winners and losers
Invasive rats on tropical islands are creating winners and losers among the tiny underwater animals near the bottom of the food chain that inhabit surrounding coral reefs. Scientists say the changes to these marine ecosystems ...
Phys.org / California wildfire damage risk map uses factors most closely linked to severe property losses
By analyzing 100,000 California Department of Forestry and Fire Protection inspection records from 2013 to 2024, researchers at the University of California, Irvine have identified the key environmental and human factors ...
Phys.org / Quantum neural networks get their first hardware test
Neural networks have transformed how machines find patterns in data, from recognizing faces in photos to predicting the shapes of proteins. So far, all of this progress has been made on ordinary classical computers, but with ...
