Phys.org / Early Cambrian fossil uncovers key buoyancy structure at the dawn of cephalopod evolution
Extant and ancient cephalopods—including octopuses, squids, extinct ammonites, cuttlefish and nautiluses—have all had to solve the problem of buoyancy, whether they have hard external shells or not.
Phys.org / Female birds have shorter lifespans than male birds across 35 North American species, researchers find
Birds have a lot to do in their short lives: defend territories, build nests, raise chicks and feed themselves. But the toll of these activities may be greater for female birds than for male birds. A new study by UCLA ornithologists ...
Phys.org / Ancient smallpox genomes reveal how European colonization brought the disease to the Americas
Researchers from Trinity College Dublin have recovered and analyzed the first ancient smallpox virus genomes ever identified in the Americas, providing the strongest direct evidence to date that the disease was introduced ...
Phys.org / Astronomers identify one of the universe's rarest black hole events
A team of astronomers at the University of North Carolina at Chapel Hill has observed an extremely rare "wandering" black hole located tens of thousands of light-years from the center of its galaxy. This finding could reshape ...
Medical Xpress / Immune navigation system discovery could lead to better treatments for chronic inflammation
A scientific collaboration between the University of Bath (UK) and the UMass Chan Medical School (U.S.) has determined how a specific type of white blood cell—neutrophils—moves through the body.
Phys.org / Scientists solve mystery of how muscle cells grow and stay healthy
In a study published in Nature Communications biophysicists unravel the mystery of how muscles form at the molecular level and maintain their function. The findings may help design treatments for muscle diseases such as dilated ...
Phys.org / Ice Age artists carved thumbnail-size bird figurines from mammoth ivory 40,000 years ago
Excavations at Hohle Fels Cave in the UNESCO World Heritage area of the Swabian Jura in southwestern Germany have again yielded two spectacular 40,000-year-old depictions of birds carved from mammoth ivory. The two figurines ...
Phys.org / Japan probe made closest-ever asteroid flyby: space agency
A Japanese probe flew 400 meters (1,312 feet) from a near-Earth asteroid this month, marking the closest approach ever recorded for such a mission, the space agency said.
Phys.org / The oceans near Australia may be the best places to fertilize for removing carbon dioxide
Deploying ocean iron fertilization—a strategy for carbon dioxide capture—in higher latitudes rather than near the equator could reduce environmental impacts while still achieving removal of carbon dioxide from the atmosphere, ...
Phys.org / New Ribo-Tweezer tool can pluck individual protein pieces out of a working ribosome
Every human cell has millions of ribosomes that make proteins. For decades, biologists thought of ribosomes as tiny, uniform machines. But now a Stanford Medicine team is showing that ribosomes are much more interesting and ...
Tech Xplore / Muscle radar unlocks potential for future robotic limbs
University of Queensland researchers have developed new noninvasive sensors that measure muscle forces, unlocking new possibilities for wearable robotic mobility devices. Ultra-wideband radar sensors measure electromagnetic ...
Phys.org / Spectroscopy system detects aerosols using light reflected from traffic signs and tree trunks
Researchers have developed and tested an infrared spectroscopy system that can rapidly detect chemical aerosols from a distance by using light reflected from common surfaces such as traffic signs, tree trunks or painted surfaces. ...
