Phys.org / Comb jelly embryos reveal embryonic signaling center shared across early animal evolution
In order for vertebrate embryos to develop their body axes, they require what is known as an embryonic signaling center. This group of cells provides the instructions that determine where up and down, left and right, and ...
Phys.org / Molecular fossils reveal secrets of Earth's recovery from ancient global warming event
Scientists have uncovered new evidence from one of Earth's most extreme ancient warming events, revealing how the climate may recover long after human-driven CO2 emissions cease.
Dialog / 'Contaminated' cultures: Can conservation protect nature while excluding Indigenous peoples?
At an international heritage symposium in Japan, I heard a word that stayed with me: "contaminated." The discussion concerned whether Indigenous peoples needed to be named explicitly in a new World Heritage framework. One ...
Phys.org / Atlantic and Pacific may follow different rules on long-term warming, analysis shows
Florida State University researchers have identified key differences in the root causes of long-term sea-surface temperature changes across the Atlantic and Pacific oceans, a finding that could help guide future research ...
Phys.org / A 19-year 'goldmine' of mountain cloud and rainwater samples provides fresh insights about air pollution
Rainfall history is just as critical to predicting air pollution as where the air came from, a team led by University of Michigan Engineering researchers, in collaboration with scientists at the Appalachian Mountain Club ...
Phys.org / Cockroach genomes are packed with DNA transferred by their endosymbiont bacterial partners
Genes aren't just transferred from parents to their offspring. Nature has found other ways to pass on genetic information, even between different species. And a new study, published in the journal Proceedings of the National ...
Phys.org / Why just sharing a stick while walking can significantly improve balance
Could the secret to preventing dangerous falls be surprisingly simple? For older adults, these unexpected tumbles are a leading cause of injury, affecting roughly 1 in 4 people 65 and older each year. What if the key isn't ...
Phys.org / AI could be trapped in a 'Carbon Valley' unless action is taken soon
AI is growing fast, and keeping up means building more data centers, manufacturing advanced chips and powering the tech behind it. All of that comes with a carbon cost. AI advocates claim that in the long run, AI will save ...
Phys.org / Baby fossils reveal link between human and Neanderthal development
An international study of infant remains from 50,000–75,000 years ago has provided new evidence about the developmental trajectory of our evolutionary "cousins," Neanderthals.
Phys.org / Quantum Hall effect gains a new twist in graphene moiré systems
Physicists have long been drawn to the nonlinear Hall effect: a subtle variant of the classical Hall effect, in which an electric voltage appears perpendicular to a current flowing through a material. Unlike its classical ...
Phys.org / Goats listen to human voices to find hidden food treats
Goats appear to have a rare ability not shared by many in the animal kingdom, and that is being able to follow the direction of a human voice to locate hidden objects. While dogs have been shown to do this, even our closest ...
Phys.org / Ancient amber fossil captures mites marching in line
Many animals exhibit fascinating collective behaviors, which allow them to move, search for food, reproduce and avoid threats more effectively than they would alone. One of these behaviors is queuing migration, which essentially ...
