Medical Xpress / Fueling growth, blinding immunity: The two-way amino acid trap inside tumors
Tumors possess myriad mechanisms to ensure their survival even at the peril of the host. Now scientists are delving deeper into how cancer cells alter the metabolism of specific amino acids to support the malignancy's growth ...
Phys.org / India's cobras share genetic ties across the mainland, while Sri Lankan cobras form a distinct genetic lineage
The spectacled cobra (Naja naja) is one of India's "big four" snakes responsible for most serious snakebite cases. It is currently considered one species, which lives across much of South Asia, with regional differences in ...
Phys.org / Shredded star reveals a massive black hole wandering far from its galaxy's center
Astronomers have discovered a star being torn apart by a massive black hole more than 1,000 parsecs from the center of its host galaxy. The tidal disruption event, TDE 2023mfm, was first discovered by ZTF and then studied ...
Medical Xpress / Popular sports supplement may help shield the brain from damage linked to gut inflammation
The gut-brain axis is a two-way biochemical hotline, with messages zipping back and forth all day long. When the gut is chronically inflamed, inflammatory signals travel through the body to the brain and trigger neuroinflammation. ...
Phys.org / Finding new ways to catch a thief—via intruders' airborne eDNA
Environmental DNA (eDNA) is increasingly being investigated by forensic scientists as a tool to help solve criminal cases that lack biological traces—and attention is also turning to collecting trace airborne eDNA left behind ...
Medical Xpress / Intensive blood pressure control protects the heart—with no added kidney failure risk detected
High blood pressure forces the heart to work harder to pump blood. Over time, this extra strain can thicken the heart muscle and narrow the arteries, further complicating cardiovascular health. Even in people with no other ...
Dialog / Could meditation reveal an SU(3) symmetry shared by the observer and the universe?
You sit down to meditate. A conversation returns, then thoughts. You bring your attention back to the breath. Sometimes, after many such returns, the effort eases. Thoughts lose their urgency, while awareness remains clear. ...
Tech Xplore / AI agents get better by anticipating errors in their own software changes
Some artificial intelligence agents can modify the programs and instructions governing their own work, with the goal of improving performance. These changes, however, can introduce errors, while testing unsuccessful modifications ...
Phys.org / Storing memory on a chip with flowing water
Like the folds in crumpled sheets or the footprints on recently trodden sand, certain materials mark their histories. Now, Yale researchers show that networks of flowing water and other fluids can store their own memories—similar ...
Phys.org / Reinforced vertebrae allow plunge-diving seabirds to survive high-speed impact
A northern gannet scans the sea for fish from 100 feet (30 meters) in the air. Upon seeing a school, it pitches its body into a nosedive, somehow breaking the surface at 70 miles per hour (113 kilometers per hour) without ...
Phys.org / Scientists uncover mystery of how snail shells coil to the right or to the left
Scientists have discovered a gene that determines whether Japanese snails develop shells that are left- or right-coiling—with implications for understanding the underlying handedness of our own bodies. The researchers from ...
Phys.org / Recycled fertilizers from sanitation systems are as effective as conventional fertilizers, study finds
Agriculture depends on a reliable supply of nutrients. Phosphorus, nitrogen and potassium, for example, are indispensable for agricultural crop production. However, natural reserves are limited, vary greatly in regional availability ...
