Dialog / When we eat helps set the liver's metabolic rhythms
When we think about metabolism, we usually ask, "What did I eat? How much sugar, fat or protein was in the meal?" But through our research, we have become interested in another question: "When did I eat it?" This matters ...
Phys.org / Tiny crustacean helps scientists understand genes regulating circatidal rhythms
Scientists at UMass Chan Medical School and the Marine Biological Laboratory at Woods Hole have shown that the four core clock genes responsible for maintaining circadian rhythms in animals—Per, Cry2, Bmal1 and Clk—also regulate ...
Phys.org / Cellular maintenance crew may miss as much as half of certain misfolded proteins
As proteins are made in a cell, they are folded into the 3D structure that allows them to work, but sometimes this process can go wrong. When it does, the misfolded proteins lose some or all of their function and usually ...
Phys.org / NASA rocket takes first multi-point look inside radio-disrupting clouds
High above Earth, thin veils of metallic haze drift through the edge of space. Known as sporadic E layers, these high-altitude "clouds" form from the vaporized dust of burned-up meteors, earning their name from the unpredictable ...
Tech Xplore / AI framework predicts ambulance speeds through city traffic
A new AI framework can predict how fast an ambulance will move through city traffic, giving fire departments a way to test emergency response strategies in a virtual environment before making changes on real streets.
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 ...
Tech Xplore / Australia needs renewable energy fast—but building it is only half the battle
Australia's energy transition has never been more urgent.
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) ...
Phys.org / Scientists discover the key ingredients that make birdsong pretty
What makes birdsong beautiful? Answering this question could help us understand how soundscapes make the natural world relaxing for humans, opening the door to improving parks, upgrading the design of stressful places like ...
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 / 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 / AI automates the creation of custom functional materials atom by atom
Imagine a construction site where the bricks are individual molecules and the "cranes" are microscopic needles so sharp they can feel a single atom. For decades, building at this scale was a laborious, time-consuming task ...
