Phys.org / Satellite images uncover new threat to emperor penguins during their annual molt
The tall black-and-white residents of Antarctica, who waddle around its icy landscape, are in peril thanks to the rapidly warming global climate. Emperor penguins go through an annual transformation called catastrophic molting, ...
Phys.org / Plant mitochondria actively pull oxygen from chloroplasts, researchers discover
A new study from the University of Helsinki reveals how plant mitochondria draw molecular oxygen away from chloroplasts, an interaction not previously documented. The discovery sheds new light on how plants regulate oxygen ...
Phys.org / Mixed-flower Australian honey packs a stronger anti-microbial punch
Honeybees collecting nectar from a "buffet" of Australian native plants made honey with anti-microbial abilities that is more potent than "single origin" honey made from only one source of plant or flower, a University of ...
Medical Xpress / Harsh parenting may cancel routine's benefits during the preschool-to-first-grade shift
Starting elementary school is a major milestone, but it can be a difficult transition as children can experience separation anxiety or have trouble adapting to school rules and structure. However, a team led by Penn State ...
Medical Xpress / Three distinct ADHD biotypes identified using a novel brain-first, data-driven approach
Attention-deficit/hyperactivity disorder or ADHD translates in different ways across the population, unlike the overgeneralized version presented on social media. A recent study further solidified this idea by identifying ...
Phys.org / Many scientists now use AI but fail to disclose it, study finds
When scientists employ generative AI tools like ChatGPT to help with tasks such as editing and translation for their academic writing, many journals now ask them to disclose this assistance. The rules are intended to maintain ...
Phys.org / Space launches are changing the chemistry of Earth's atmosphere, studies warn. Here's what can be done
Look up on a clear night and you'll see the streaks of our new space age. What you don't see is the growing fallout for the atmosphere that keeps us alive.
Phys.org / Study reveals new technique to identify individual night-flying birds for the first time
Millions of birds invisibly migrate through the night sky each autumn, most flying in near silence toward their wintering grounds. Now, scientists have developed a way to see and identify many of those birds for the first ...
Phys.org / A superradiant clock phase emerges when Rydberg atoms meet quantum light, simulations suggest
Rydberg atoms are atoms with one or more outer electrons excited to very high energy levels, which interact very strongly with each other. These atoms are widely used to run quantum simulations and develop quantum technologies, ...
Phys.org / DART images reveal asteroids can toss slow 'cosmic snowballs' between moons
About 15% of asteroids near Earth have small moons orbiting them, making binary asteroid systems common in our cosmic neighborhood.
Phys.org / Study finds biodiversity credits could boost rewilding, but fall far short
Payments that enable landowners to rewild ecologically degraded land—in the form of biodiversity credits bought by investors wishing to offset their impact on nature—could be an effective component of the emerging market ...
Phys.org / Scientists create a hexagonal diamond that could be even harder than the real thing
To misquote a famous song, "Diamonds are industry's best friend." Cubic diamond is the hardest mineral on Earth and is used in everything from precision cutting tools to high-performance semiconductors as well as expensive ...
