Phys.org / Stardust study resets how life's atoms spread through space
Starlight and stardust are not enough to drive the powerful winds of giant stars, transporting the building blocks of life through our galaxy. That's the conclusion of a new study from Chalmers University of Technology, Sweden, ...
Phys.org / Toddlers with facial tattoos: How Christianity expanded body art in Nile Valley civilizations
Ancient Nubians who lived between the 7th and 9th centuries tattooed the cheeks and foreheads of their infants and toddlers. This surprising discovery was made during a systematic survey of more than 1,000 human remains from ...
Phys.org / Decades-long quest leads to first scholarly accurate fossil replica of 'dinosaur-killer' croc
Dr. David Schwimmer, an expert on the giant North American crocodilian genus Deinosuchus and a Columbus State University geology professor, has contributed his research to the creation of the first-ever scholarly accurate, ...
Phys.org / AI uncovers double-strangeness: A new double-Lambda hypernucleus
Researchers from the High Energy Nuclear Physics Laboratory at the RIKEN Pioneering Research Institute (PRI) in Japan and their international collaborators have made a discovery that bridges artificial intelligence and nuclear ...
Phys.org / Simulations explore Neanderthal and modern human encounters in ancient Europe
Using a specially developed simulation model, researchers at the University of Cologne have traced and analyzed the dynamics of possible encounters between Neanderthals and anatomically modern humans on the Iberian Peninsula ...
Phys.org / Deepest gas hydrate cold seep ever discovered in the Arctic at 3,640 m depth
A multinational scientific team led by UiT has uncovered the deepest known gas hydrate cold seep on the planet. The discovery was made during the Ocean Census Arctic Deep–EXTREME24 expedition and reveals a previously unknown ...
Phys.org / PFAS concentrations can double with every step up the food chain
A new UNSW-led global meta-analysis shows that PFAS concentrations can double at every step up the food chain, leaving top predators—and humans—potentially exposed to higher chemical loads.
Phys.org / ALMA observations reveal multiscale fragmentation in massive star formation
Researchers from Yunnan University, the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences, and the National Astronomical Observatory of Japan have unveiled new insights into the fragmentation mechanisms ...
Phys.org / Artificial metabolism turns waste CO₂ into useful chemicals
In a breakthrough that defies nature, Northwestern University and Stanford University synthetic biologists have created a new artificial metabolism that transforms waste carbon dioxide (CO2) into useful biological building ...
Phys.org / Ancient sea anemone sheds light on animal cell type evolution
One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet still gives rise to a kaleidoscope of different cell types and tissues. A neuron doesn't look nor behave ...
Phys.org / The sound of droplets striking water: How cowbirds control two sound sources in the syrinx to create 'liquid notes'
Cowbirds are special among songbirds for the "watery" timbre of their singing, which resembles the sound of falling droplets striking water, a quick burst followed by a fading ripple.
Phys.org / Warming may make tropical cyclone 'seeds' riskier for Africa
An existing body of research indicates that climate change is making tropical cyclones wetter and more powerful. Now, a new study is indicating the same thing may be happening to the precursors of these storms: the wet weather ...
