Phys.org / Poking a nanostring: Scientists uncover energy cascades in tiny resonators
Scientists at TU Delft have designed a nanostring that, when poked, doesn't lose its energy to the environment immediately. Instead, the energy leaks out within the string, triggering a cascade of distinct vibrational modes. ...
Phys.org / Discovery of natural mechanism behind ferroptosis solves longstanding puzzle in cell biology
After more than a decade of research, scientists have discovered the natural mechanism behind a novel form of cell death called ferroptosis. The work, described in the current issue of Cell, points toward an entirely new ...
Phys.org / Late scientist's notebooks help finish study of rare 55-million-year-old tarpon fossil
Recently-revealed notebooks belonging to a late paleontologist contain the missing information needed to help researchers finish their study of a remarkable fossil discovered nearly three decades ago.
Phys.org / Brain structure volume linked to increased social tolerance in macaques
Researchers have found that the size of the amygdala—a region of the brain involved in processing emotions—could be linked to social tolerance in macaque monkeys. Their research, published today in eLife, is described ...
Phys.org / Four decades of data give unique insight into the sun's inner life
Scientists have analyzed more than 40 years of astronomical data to uncover evidence that the sun's internal structure subtly changes from one solar cycle minimum to the next. Publishing their findings in Monthly Notices ...
Phys.org / Paternal mitochondria in plants can rescue defective maternal DNA, study reveals
In most plants and animals, including humans, mitochondria are inherited exclusively, or nearly exclusively, from the mother. By contrast, paternal transmission is observed only occasionally, and the mechanisms behind this ...
Phys.org / Newly excavated Maya wetland settlement shows the civilization's adaptation to changing climate
Past civilizations have been significantly affected by climate change, but how they adapted to new conditions centuries ago is less clear. In research newly published in the Proceedings of the National Academy of Sciences, ...
Phys.org / Studying snakes' ability to stand upright could inform soft robotics and more
Snakes may be best known for slithering. But consider that these animals also perform one of the most extreme feats of posture control found in nature: They can stand nearly straight upright on a narrow perch without falling, ...
Phys.org / Jackdaw chicks listen to adults to learn about predators
Jackdaw chicks learn about predators by listening to adults, new research shows. Scientists played recordings of predator calls to chicks in their nests—and paired the sounds with either adult jackdaw "alarm" calls or "contact" ...
Phys.org / The 'Bloom cycle' is a newly described biochemical pathway that explains key plant processes
For decades, the basics of plant growth have been taught in grade school: Plants make their food out of water from the soil, light from the sun and carbon dioxide from the air in a process called photosynthesis. What gets ...
Medical Xpress / 7 hours 18 mins may be optimal sleep length for avoiding type 2 diabetes precursor
Sleeping for 7 hours and 18 minutes every night may be the sweet spot for warding off the risk of insulin resistance—the precursor to type 2 diabetes—suggests a large observational study published in the open access journal ...
Tech Xplore / Deepfake songs are exploding, but a new tool shuts them down
Artificial intelligence models can now clone a voice with just a few seconds of audio, fueling a surge of deepfake songs online and creating a growing crisis for musicians who don't want their voices hijacked. Beyond the ...
