Phys.org / Life with one less: Engineered bacteria break the 20-amino-acid rule
One of life's many mysteries is how it ended up choosing only a set of 20 amino acids to build proteins for its wide catalog of organisms, from single-celled bacteria to behemoth whales. From a chemical standpoint, many of ...
Phys.org / Physics-based weather models more accurate than AI at predicting extreme weather
Weather forecasting is another aspect of modern life that artificial intelligence is transforming. Models like GraphCast, Pangu-Weather, and Fuxi are already better than traditional physics-based climate models at predicting ...
Phys.org / Drivers help study road-trip mystery: what became of bug splats?
Long an emblem of the summer road trip, squashed bugs on the car have become less numerous over the years, many people say—causing concern about the health of the world's insect populations.

Tech Xplore / Can AI ascertain our personality traits from our ChatGPT history?
Large language models (LLMs), the computational models underpinning the functioning of ChatGPT, Gemini, and similar conversational platforms, are now used daily by many people worldwide. As these models can rapidly answer ...
Phys.org / Buried electrical pathways across the US reveal new clues about Earth's interior and power grid risks
A solar storm like the one that caused a nine-hour blackout across Quebec in 1989 could have even more dramatic effects if it struck the eastern United States today. Now, scientists have developed new tools to detect these ...
Medical Xpress / Omega-3 supplements may be linked to faster cognitive decline in seniors, study finds
Omega-3 supplements are popular among many older adults to help combat age-related issues. They are often marketed as supporting cardiovascular health and reducing the risk of cognitive decline and dementia. However, a new ...
Phys.org / A tiny world beyond Neptune has an atmosphere that shouldn't exist
A team of professional and amateur Japanese astronomers have found evidence for a thin atmosphere around a small body in the outer solar system. The object is so small that it should not have a sustainable atmosphere, raising ...
Phys.org / A lost galaxy called 'Loki' may be hiding inside the Milky Way
The Milky Way galaxy grew into its current form with the help of smaller galaxies over time, which it has "consumed" or merged with. Astronomers are able to pick out which stars in the Milky Way came from other galaxies by ...
Phys.org / DESI-HVS1 is an old hypervelocity star ejected from the galactic center, observations suggest
Chinese astronomers report the discovery of DESI-HVS1, which may be an old metal-poor hypervelocity star of galactic center origin. The finding, based on the data from the Dark Energy Spectroscopic Instrument (DESI) and ESA's ...
Phys.org / A better way to search for extraterrestrial intelligence
When you're looking for signs of extraterrestrial intelligence, it helps to know what you're looking for and to go about it in the most efficient way. But work so far has generally not done so, writes Benjamin Zuckerman, ...
Phys.org / We might have massively underestimated Io's thermal output
Io is a world of extremes. It is by far the most volcanically active world in our solar system. Being continually squeezed in the never-ending tug-of-war between Jupiter and its larger satellites will do that to a moon. As ...
