Phys.org / Drill core reveals asynchronous land–ocean responses to ancient ocean anoxia
Earth experienced a period of intense, large-scale volcanism during the early Aptian. Around that time, it also experienced widespread ocean deoxygenation during the Oceanic Anoxic Event 1a (OAE1a) as well as the onset of ...
Phys.org / Vocal analysis and AI uncover two new Amazon antbirds in five-species complex
Scientists have discovered that a widely recognized Amazonian antbird is not one, but five distinct species—including two completely new to science. This revelation of hidden biodiversity was achieved by integrating artificial ...
Phys.org / Antibacterial coatings with short-term effect may fail over longer periods of time
Researchers from the Institute of Physics and the Institute of Molecular and Cell Biology of the University of Tartu have shown in a recently published study that antibacterial coatings which initially appear highly effective ...
Phys.org / Evolution of new physical traits in mollusks has declined and grown more predictable over time
Paleobiologist Geerat Vermeij is enthralled with mollusks. Their shells line the surfaces and fill the cabinets and drawers in his office on the second floor of the Earth and Planetary Sciences Building at UC Davis. But Vermeij's ...
Phys.org / Salmonids reveal the cold truth about human impacts on Fennoscandian lakes
A large-scale study led by the University of Jyväskylä revealed that human activity is consistently changing the ecosystems of Northern European lakes. The study shows that hydropower and human activity in catchment areas ...
Phys.org / How pro- and anti-gun PAC contributions after school shootings effectively neutralize each other
Polls consistently show overwhelming support for measures like universal background checks and raising the minimum age for gun purchases. But Congress rarely acts. A new study published in Proceedings of the National Academy ...
Phys.org / Left-handed people may have a psychological edge in competition
Left-handers are more competitive than right-handers, according to a new study published in the journal Scientific Reports. The findings may help explain why left-handedness has persisted throughout evolution despite the ...
Phys.org / Study finds 77% of US national parks are highly vulnerable to climate change
National parks in the United States represent a treasure trove of natural, historical, and recreational landscapes, but their health is at risk. A comprehensive new study on the climate-change vulnerability of national parks, ...
Phys.org / Brazilian fossil site yields smallest rhynchosaur fossil ever recorded
A study published in the Journal of Systematic Palaeontology describes the smallest rhynchosaur fossil ever recorded from the Brazilian Triassic, with the reconstructed skull only measuring around 2.5 cm (~1 inch). Additionally, ...
Phys.org / Hidden atomic dichotomy drives superconductivity in ultra-thin compound
Physicists in China have unveiled new clues to the origins of high-temperature superconductivity in an iron-based material just a single unit-cell thick. Led by Qi-Kun Xue and Lili Wang at Tsinghua University, the team's ...
Phys.org / How an underground fungal map of the world's oldest, slowest-growing rainforest trees can boost Earth's resilience
The temperate rainforests of the Chilean Coast Range are home to a spectacular array of life: iridescent blue lizards, tiny wild cats called kodkods, and curly vines of waxy red bellflowers. Towering over this biodiversity ...
Phys.org / Wildlife imaging shows that AI models aren't as smart as we think
Using AI to identify wildlife reveals a potential "transferability crisis," researchers say. Marketing for AI imaging systems often suggests that models can easily tackle novel scenarios across ecosystems and settings, much ...
