Medical Xpress / Vitamin C levels in blood plasma linked with brain connectivity and volume in older adults
A study of 2,044 older Japanese adults found that those with lower vitamin C levels in their blood plasma tended to have a lower volume of gray matter in their brains, as well as lower connectivity among a collection of brain ...
Phys.org / Young coqui frogs 'play it safe' when disease strikes, study finds
For a frog no bigger than a fingernail, survival depends on how it spends every bit of energy. New research from the University of Florida shows that young frogs prioritize growing quickly even when infected with a deadly ...
Phys.org / Pixels preserve world's rarest porpoise to 3D digital archive as extinction risk grows
The vaquita (Phocoena sinus), an elusive porpoise found only in the shallow waters of Mexico's northern Gulf of California, is one of the rarest and most endangered marine mammals on Earth. Measuring about 5 feet (1.5 meters) ...
Phys.org / Female chickadees seek cognitively skilled males for extra‑pair matings, study shows
Female chickadees living in monogamous mating systems will proactively seek out males that have better cognitive skills than their nest mate, according to new findings.
Phys.org / Water-based nanoprinting moves metal films onto delicate 3D surfaces without damage
A new technology allows metal circuits floating on water to be transferred directly onto any desired surface. A South Korean research team has introduced a novel technique capable of transferring ultra-fine nanocircuits onto ...
Medical Xpress / Everyday chemical exposures linked to preterm birth and lower birthweight
In one of the largest studies of chemical exposures during pregnancy to date, new research led by the UNC Gillings School of Global Public Health, Stanford University School of Medicine and Woods Institute for the Environment ...
Phys.org / Distant ocean temperatures found to influence snowfall in Antarctica
Snowfall deep inside East Antarctica has increased in recent decades, and distant ocean temperature changes may be partly responsible. Using long-term climate data and observations from Dome Fuji station, researchers found ...
Phys.org / Chemists reveal one-step 'alkyl swap' that rewrites key amines for drug discovery
For more than a century, chemists have been building complex molecules step by step—bond by bond, atom by atom. But what if, instead of painstakingly reassembling molecules, they could be directly "rewritten"? This is exactly ...
Phys.org / Lava planet has hydrogen-rich, active atmosphere
It's 2158, and you're chugging away on your Ph.D. in planetary volcanology from the University of Utopia Planitia on Mars. Graduate students still get paid a sub-living wage, so you've been stuck eating freeze-dried ramen ...
Medical Xpress / Newborn neurons routinely break then repair DNA during brain cortex formation, study reveals
Newborn nerve cells must squeeze through crowded, narrow spaces—through dense tissue, past other cells, and between fibers—to reach the areas where they form neural circuits in the brain cortex. In a study published in Nature, ...
Tech Xplore / Nanoengineered wood sets new record for transformer insulation
The world's power grid is straining under the surge in electricity demand from data centers, electric vehicles and renewable energy. And a century-old technology, the power transformer, must support this dramatic increase. ...
Phys.org / Q&A: Do high-pressure environments encourage moral disengagement?
Why do individuals and organizations sometimes rationalize decisions that conflict with their stated values? According to Leah P. Hollis, professor of education policy studies in the Penn State College of Education, the answer ...
