Medical Xpress / Depression and tau pathology linked to faster rise in risky driving among older adults
Driving is a complex skill that involves a wide range of mental processes and abilities. Drivers need to pay close attention to what is happening around them, remember the meaning of road signs, respond quickly to unexpected ...
Phys.org / Hidden chemical pathway could keep phosphorus from fueling lake algal blooms
Why do some lakes remain plagued by harmful algal blooms even after phosphorus pollution has been reduced? Part of the answer lies beneath the surface. A new Concordia study has uncovered a previously overlooked chemical ...
Phys.org / Scarce emergence of new species drove the decline of African megaherbivores, study suggests
A study by the National Museum of Natural Sciences (MNCN-CSIC), the National Research Center on Human Evolution (CENIEH) and the University of Alcalá offers a new explanation for the decline of African megaherbivores. These ...
Phys.org / Ruby-forming mineral found by Mars rover hints at violent impacts
So far, most of the minerals found on Mars tell a story of lava poured out by ancient volcanoes, followed by long stretches in which water trickled through and slowly reshaped the rock. However, some rocks scattered across ...
Phys.org / A new approach to building noise-resistant quantum sensors
Quantum sensors, devices that collect measurements by exploiting quantum-mechanical phenomena, could potentially detect extremely weak magnetic, gravitational and electromagnetic signals with greater sensitivity than classical ...
Phys.org / Seeing the unseen: A new tool visualizes hidden structures in complex biological data
Modern biology research can now generate valuable data on an unprecedented scale. But there is one major obstacle: making sense of these complex high-dimensional datasets. A team at the University of Basel, Switzerland, has ...
Phys.org / Iron hydride enters an exotic state of matter under Earth's inner-core conditions
Earth's inner core, composed primarily of iron with a small percentage of light elements, may enter a superionic state at extreme pressure and temperature, according to experimental results from researchers at Science Tokyo. ...
Phys.org / Stellar spin may explain why repeated black hole flares grow dimmer
At the center of most galaxies lies a supermassive black hole, with a mass millions to billions of times that of our sun and some of the most extreme gravity in the universe.
Phys.org / Turning a quantum battery's environmental sensitivity into an advantage
Quantum batteries, devices that store energy by exploiting quantum mechanical phenomena, could, in principle, be charged faster and more efficiently than classical ones. Despite their potential, connecting these batteries ...
Phys.org / Twenty years and 7,500 fossils reveal what blurs Earth's marine fossil record
In productive marine environments, a square meter (10.8 square feet) of seafloor can be perforated by hundreds to thousands of isolated and interconnected tunnels through which crawl and writhe a cornucopia of clams, shrimp, ...
Phys.org / China's solar push linked to bird diversity losses across 2,344 counties
The global push for solar energy expansion could carry hidden biodiversity costs, according to a study on China published in the journal Science on Thursday.
Medical Xpress / High-dose vitamin D may improve cognition among those at risk of dementia, study finds
With more than 7 million Americans living with Alzheimer's dementia—a number projected to reach nearly 13 million by 2050—new Emory University research suggests that higher vitamin D supplement intake may be associated with ...
