Phys.org / Copper's oxygen-rich early oxidation layer could inform catalyst design and nuclear waste storage
Copper roofs lose their reddish color over time because a pale green layer of copper oxide forms on their surface, protecting the roof from further corrosion for many years. But what exactly happens during the first steps ...
Phys.org / Farewell black spruce? How climate change and pests are reshaping North America's forests
More than 80% of North American forests could face greater threats from pests and diseases by midcentury, a University of British Columbia-led study finds. If global emissions continue unchecked, rising temperatures and shifting ...
Tech Xplore / Thousands of OpenAI AI agents took over German website, researchers say
Thousands of autonomous AI agents built by OpenAI defied their instructions and took over a German website, according to research released Friday, amid fears that the dangers of artificial intelligence are not being taken ...
Phys.org / Deadly floods of 2021—Researchers identify gaps in hazard mapping
The catastrophic flooding in July 2021 claimed the lives of more than 200 people in Germany and Belgium. The high death toll makes it clear that hazard mapping and risk communication must be improved urgently. Researchers ...
Phys.org / Ancient fossil from China reveals animal‑microbe partnerships dating back 550 million years
We often think of microbes as organisms that live around us, like the Salmonella bacteria and flu viruses that cause illness. But some of our most intimate relationships are with the microbes living inside us.
Medical Xpress / Five subtypes of common liver disease discovered—including rapidly progressing genetic forms
A liver disease affecting nearly 30% of adults worldwide is not a single illness but five biologically distinct subtypes, Mayo Clinic researchers have found. Each carries different risks for heart disease, liver failure, ...
Phys.org / When panic freezes people: Virtual quake tests capture real-time fear and injury risk
Growing up, many of us were taught to drop, cover and hold on during an earthquake. The guidance is straightforward, but how people actually respond when the ground starts shaking can be far more complicated. Now, UC Berkeley ...
Phys.org / Metabolic networks provide clues about the earliest stages of enzyme evolution
The enzymes found in modern organisms are complex proteins, often with multiple folded substructures and specialized catalytic sites. Proteins are encoded by genes. Tracing the history of enzymes across all living organisms ...
Phys.org / Before mixing starts, initial catalyst structure governs fuel-cell ink dispersion
Researchers from Kanazawa University, the University of Tokyo and HORIBA, Ltd. have shown that the initial state of platinum-on-carbon (Pt/C) catalyst particles before they are mixed with an ionomer strongly influences how ...
Phys.org / In tune with nature: Human speech follows a rhythm that is also found in the animal kingdom
The temporal structure of speech rhythms resembles that of the communication signals of numerous animal species. This is shown by a study conducted by a research team from the Leibniz Center for General Linguistics (ZAS) ...
Medical Xpress / T cell protein could unlock new treatment for the most-feared joint replacement complication
Bone and joint infections cause significant health problems for patients and lead to millions of dollars in added health costs per year, but clinicians lack reliable tools to predict which patients will develop severe or ...
Phys.org / Nature's color palette explains why everything we see is a mix of red, yellow, green and blue
Biologists and linguists alike have long puzzled over the universal human tendency to see and name colors as a combination of four "pure" hues—red, yellow, green and blue.
