Medical Xpress / Deciding for others can lower confidence in one's own judgments
From the moment we wake to the time we hit the bed at night, we make numerous decisions, some big but mostly small. Although decision-making is a fundamental part of human life, researchers have found that the level of difficulty ...
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 / 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 / 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 / 'Mismatched' plant water isotopes vanish with better sampling: Study points to better drought forecasts
For decades, scientists have relied on a chemical fingerprint inside water molecules to determine where plants get their moisture. The method shaped our understanding of drought resilience, groundwater use, and ecosystem ...
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 ...
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 ...
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 / How an underground fungal map of the world's oldest, slowest-growing rainforest trees can boost Earth's resilience
The temperate rainforests of the Chilean Coast Range are home to a spectacular array of life: iridescent blue lizards, tiny wild cats called kodkods, and curly vines of waxy red bellflowers. Towering over this biodiversity ...
Phys.org / A fanged frog long thought to be one species is revealing itself to be several
When a new species is discovered, it's tempting to imagine an adventure novel, said Chan Kin Onn of Michigan State University. "Most people have this image of an intrepid explorer braving an isolated mountain or some other ...
Phys.org / Hard-to-make diastereomers: How a cage-like allyl reagent changes the outcome
Diastereomers are structurally identical molecules that are not mirror images of each other. Diastereomers can have different biological activities, potencies or toxicities, which means they can influence biological systems, ...
Tech Xplore / Europe should focus on industrial AI, SAP says
Europe should focus on competing in industrial AI, a top executive at German software giant SAP said, as the continent plays catch-up in the race for the cutting-edge technology against the United States and China.
