Phys.org / GRIT remaps the world's rivers, branching into the unknown to aid global flood modeling
A team led by researchers at the University of Oxford has created the most complete map of the world's rivers ever made, offering a major leap forward for flood prediction, climate risk planning, and water resource management ...
Phys.org / Nerve fibers enabling language connection discovered in chimpanzee brains
Language processing in humans depends on the neuronal connection between language areas in the brain. Until recently, this language network was thought to be uniquely human.
Phys.org / AI predicts bacterial resistance to cleaning agents
A group of researchers, including scientists from the DTU National Food Institute, have developed a method that, with the help of artificial intelligence and DNA decoding, can predict how well disease-causing bacteria such ...
Phys.org / Stem cell model replicates human amniotic sac development past two weeks
Researchers at the Francis Crick Institute have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. ...
Phys.org / A plant hormone's secret passage: Researchers elucidate molecular mechanism of auxin influx
Auxin is the first plant hormone—or "phytohormone"—ever identified, with its discovery dating to the late 19th and early 20th centuries. With its discovery, scientists began to understand how small, self-produced organic ...
Phys.org / Plants ignore gravity during droughts to forage for water
Roots "feel" gravity to extend and anchor themselves in the soil, but they can alter their growth direction toward a water source when needed. However, according to a new study by scientists at the Institute of Science and ...
Phys.org / Dual associations with two fungi found to improve tree fitness
When trees and soil fungi form close associations with each other, both partners benefit. Many tree species have further enhanced this cooperation by forming a concurrent symbiosis with two different groups of mycorrhizal ...
Phys.org / Queensland sites offer play and rest for migrating humpbacks
A new study has compared how migrating humpback whales use two stopover sites along the Queensland coast, finding that one was more social in nature and the other was used primarily by mothers and calves.
Phys.org / Sea expedition helps unravel why mercury levels are so high in the Arctic
Mercury (Hg) is a naturally occurring element found across the globe, yet it becomes highly toxic as it accumulates up the food chain. Pollution from human activities has pumped increasing amounts of mercury into the atmosphere, ...
Phys.org / This flat-bodied South African gecko was a 'lost' species. It's been found again after 34 years
Researchers who were dropped off by helicopter in a largely inaccessible and remote canyon in South Africa say they have discovered a type of gecko that hadn't been seen in more than 30 years and was thought to be extinct—or ...
Phys.org / How whisker-generated sounds are encoded in the auditory cortex of mice
Nestled in dark burrows, with a limited sense of vision, mice brush their whiskers against their environment to navigate and to detect objects around them. This behavior, termed whisking, has been extensively studied in the ...
Phys.org / Ancient ambidextrous protein breaks the rules of molecular handedness
A study has found that an ancient protein motif that binds to nucleic acids is functionally "ambidextrous." This means that the motif can interact with both natural and mirror-image nucleic acids, an occurrence that has never ...
