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 ...

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, ...
