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 / 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 / Mercury reveals short-lived radiation belts during its swing farther from the sun
Mercury was long considered the exception to the rule that magnetic planets have radiation belts similar to Earth's Van Allen belts, but a new study by University of Michigan Engineering and the University of California, ...
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 / Simple semiconductor films break light's front-back symmetry
Light typically interacts with a material the same way whether it enters through the front or the back—like polarized sunglasses that work the same from either side. Cornell researchers have demonstrated a simple route to ...
Phys.org / Light reveals transient electronic step behind a hidden state in metal-organic framework
A fleeting photoinduced electronic state and the subsequent formation of a photoinduced hidden state in a metal–organic framework were captured in just 30 femtoseconds by researchers at Science Tokyo, Tohoku University and ...
Phys.org / Biodegradable implant can deliver targeted cancer immunotherapy while protecting healthy tissue
Scientists at Houston Methodist Research Institute have developed a biodegradable implant designed to deliver cancer-fighting immunotherapy drugs directly into tumors over an extended period, a strategy that could improve ...
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 ...
Medical Xpress / The stomach helps the brain form memories—this is how it may work
When French writer Marcel Proust famously recalled his childhood from the taste of a Madeleine cookie, his stomach may have done some of the work. We generally associate our memories almost exclusively with the brain, which ...
Phys.org / Physicists capture first direct evidence of a Floquet topological state
A new study published in Nature Physics reports the first direct experimental evidence of a Floquet topological state, a novel light-induced phase of matter that, until now, has existed only on paper and in simulations. Topological ...
Tech Xplore / AI gains a tool to identify Kinyarwanda propaganda, with promise for 600 Bantu languages
A new study led by Fabrice Niyigaba '27 reports the first digital tool for identifying online propaganda in Kinyarwanda, the national language of Rwanda's 15 million people—and possibly the first for any of the Bantu languages ...
Phys.org / First 3D views explain how primate cone pigments distinguish red from green
Human color vision depends on three types of cone cells in the retina. Although all three contain the same light-absorbing molecule, 11-cis-retinal, differences in the surrounding protein determine sensitivity to red, green ...
