Phys.org / Antarctica sits above Earth's strongest 'gravity hole.' Now we know how it got that way
Gravity feels reliable—stable and consistent enough to count on. But reality is far stranger than our intuition. In truth, the strength of gravity varies over Earth's surface. And it is weakest beneath the frozen continent ...
Medical Xpress / After four days with a robotic leg, people still misread how they walk
The way we understand the movement of our own bodies plays an important role when learning physical skills, from sports to dancing. But a new study finds this phenomenon works very differently for people learning to use robotic ...
Phys.org / Amazon rainforest flipped to carbon source during 2023 extreme drought, study shows
The Amazon rainforest is of crucial importance to the Earth's ecosystem, given its capacity to store substantial amounts of carbon in its vegetation. In 2023, the region experienced unusually high temperatures, reaching 1.5°C ...
Phys.org / New species of ancient crocodile named in honor of Welsh school teacher
A new species of crocodylomorph dating to about 215 million years ago has been described from the U.K. It has been called Galahadosuchus jonesi in recognition of David Rhys Jones, a secondary school physics teacher from Ysgol ...
Phys.org / Extreme rainfall is worsening algal blooms along South Korea's coast
Extreme rainfall is reshaping coastal waters along South Korea's shoreline, flushing nutrients from land into the sea and fueling the growth of algal blooms. A new multi-year study, published in Frontiers in Marine Science, ...
Phys.org / How 1.5 million km of undersea internet cables can double up as an earthquake and tsunami warning system
Forecasting earthquakes presents a serious challenge on land, but in the oceans that cover around 70% of Earth's surface it is all but impossible. However, the vast network of undersea cables that crisscross the world's seas ...
Phys.org / Offshore wind farms change ocean current patterns, simulations show
By 2050, offshore wind power capacity in the North Sea is set to increase more than tenfold. Researchers at the Helmholtz Center Hereon have analyzed the long-term overall impact of this large number of wind farms on the ...
Tech Xplore / Why AI may overcomplicate answers: Humans and LLMs show 'addition bias,' often choosing extra steps over subtraction
When making decisions and judgments, humans can fall into common "traps," known as cognitive biases. A cognitive bias is essentially the tendency to process information in a specific way or follow a systematic pattern. One ...
Phys.org / Laser-made surface repels nearly any liquid, even after fivefold stretching
Researchers from North Carolina State University have used laser ablation to create ultra-stretchable, superomniphobic materials without the use of harsh chemical solvents. The materials—which are useful in applications ...
Phys.org / Scientists build successful 'cloud in a box'
In a quiet laboratory, a team of atmospheric scientists and engineers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory recently gathered around a workstation to watch as little floating speckles, illuminated ...
Phys.org / Researchers measure Puijo lichens and microbes for canopy nitrous oxide uptake
The role of soil and forests in greenhouse gas sequestration has been studied for a long time. However, forests are also home to invisible organisms that may affect the climate. "Soil, water and peatlands have been studied ...
Medical Xpress / Ostarine: The performance-enhancing drug giving anti-doping agencies a headache
A drug designed to help cancer patients rebuild wasting muscles has become one of the most contentious substances in elite sport—and the scientist who discovered it now spends more time trying to stop people using it than ...
