Phys.org / Deep-sea volcanoes: Windows into the subsurface
Hydrothermally-active submarine volcanoes account for much of Earth's volcanism and are mineral-rich biological hotspots, yet very little is known about the dynamics of microbial diversity in these systems. This week in PNAS, ...
Phys.org / Fingerprints' moisture-regulating mechanism strengthens human touch: study
Human fingerprints have a self-regulating moisture mechanism that not only helps us to avoid dropping our smartphone, but could help scientists to develop better prosthetic limbs, robotic equipment and virtual reality environments, ...
Phys.org / Researchers offer new theory on 'Venus' figurines
One of world's earliest examples of art, the enigmatic 'Venus' figurines carved some 30,000 years ago, have intrigued and puzzled scientists for nearly two centuries. Now a researcher from the University of Colorado Anschutz ...
Phys.org / New device offers faster way to detect antibiotic-resistant bacteria
Bacterial infections have become one of the biggest health problems worldwide, and a recent study shows that COVID-19 patients have a much greater chance of acquiring secondary bacterial infections, which significantly increases ...
Phys.org / Flashy lizards are more attractive to mates and to predators
In the lizard world, flashy colors attract the interest of females looking for mates. But they can make colorful males desirable to other eyes, too—as lunch.
Medical Xpress / Child HIV treatment cost slashed: Unitaid
A strawberry-flavoured HIV treatment for the 1.7 million children living with the virus will slash the cost of yearly paediatric treatment by three quarters, Unitaid announced on World AIDS Day.
Phys.org / Indian astronomers detect companion star to V1787 Ori
Astronomers from India have reported the finding of a companion star to an intermediate-mass Herbig Ae star known as V1787 Ori. The newly detected object turns out to be of M-type and is about 60% less massive than our sun. ...
Medical Xpress / Cortex over reflex: Study traces circuits where executive control overcomes instinct
When riding your bike to the store you might have two very different reasons to steer: plain old reflex when you something dart into your path, or executive control when you see street signs that indicate the correct route. ...
Phys.org / Researchers explore population size, density in rise of centralized power in antiquity
Early populations shifted from quasi-egalitarian hunter-gatherer societies to communities governed by a centralized authority in the middle to late Holocene, but how the transition occurred still puzzles anthropologists. ...
Medical Xpress / Mystery still shrouds COVID-19 origin
While many scientists are racing to find vaccines to tame the spread of the coronavirus pandemic, other researchers are probing the past, trying to unravel one of the greatest mysteries of the virus: exactly where it came ...
Phys.org / Abnormal conductivity in low angle twisted bilayer graphene
Materials scientists can control the interlayer twist angle of materials to offer a powerful method to tune electronic properties of two-dimensional (2-D) van der Waals materials. In such materials, the electrical conductivity ...
Phys.org / Recombinant collagen polypeptide as a versatile bone graft biomaterial
The current gold standard for bone grafting surgery includes autografts and allografts, although a growing demand exists to develop synthetic biomaterials for enhanced bio-integration in bone tissue engineering. In a new ...
