Phys.org / How signals in the embryo tell cells what to become: A lab's final discovery
Getting it over the finish line was a labor of love—and now, more than five years after her death, the lab of former Sloan Kettering Institute Developmental Biology Chair Kathryn Anderson, Ph.D., is publishing its final study.
Phys.org / Deliberate slow growth could explain bacteria survival strategies
Escherichia coli (E. coli) are mostly harmless bacteria that live in the intestines of animals and humans. They are the most well-studied bacteria and, often, when scientists discover something about E. coli, they extrapolate ...
Phys.org / Last-minute launch problem delays satellite rescue mission for NASA
A rush rescue mission to save a NASA space telescope remains grounded, this time because of a last-minute launch problem.
Phys.org / Simulation reveals how glaciers transported rocks across the Alps 24,000 years ago
Many of the boulders scattered across the Swiss landscape did not originate where they now stand. Instead, they were carried by ice nearly 24,000 years ago. For the first time, researchers at the University of Lausanne (UNIL) ...
Phys.org / Austin neighborhood tap water tests uncover lead and arsenic in homes
For more than a decade, residents of Austin's Colony, a neighborhood in an unincorporated area of southeast Austin outside the city service area, have voiced concern about their tap water's intermittent discoloration and ...
Phys.org / Massive sturgeon once bred in Britain's rivers, boosting reintroduction hopes
Atlantic and European sturgeon once called Britain's rivers home and could do so again, following research using Natural History Museum specimens. These fish are among the biggest found in Europe and undertake epic migrations ...
Phys.org / Coral loss may erase up to $3 billion in Hawaiʻi reef recreation by 2100
Coral reef decline driven by climate change could cost Hawaiʻi residents between $1.8 billion and $3 billion in lost reef-related activities by 2100, according to a new study published in Ecological Economics. The research ...
Phys.org / More Canadian than the beaver? Scientists discover a western toad found only in Canada
The beaver and moose may be enduring symbols of Canadian wildlife, but neither is uniquely Canadian from a genetic perspective. But a team of researchers from the University of Ottawa has now discovered something rare: a ...
Phys.org / Scourge of satellites lighting up the sky could be mitigated with help of ultra-black coating
Astrophysicists working to tackle the growing impact of satellite constellations have pioneered a new ultra-black coating as one possible way to mitigate the problem.
Phys.org / How much do friends influence teens' mental health? What a new study can (and can't) tell us
During adolescence, young people become especially sensitive to peer influence—more so than at any other time in life. So how does this affect their mental health?
Phys.org / Ecological factors, not social behavior, explain brain size in cephalopods
Octopuses, squid and cuttlefish may have evolved large brains because of the challenges posed by their environments rather than the demands of social life, according to a new study published in iScience today.
Phys.org / Honeybee queens push pesticides to eggs to protect themselves over their offspring, research reveals
Worker bees are the first line of defense when it comes to removing contamination in honeybee colonies, but a queen has her ways, too. A honeybee queen facing chronic exposure to pesticides will take up that contamination ...
