Phys.org / New method reveals how virus particles can build themselves, molecule by molecule
Oxford University researchers have captured the step-by-step assembly of individual virus-like particles, revealing how simple molecular interactions can reliably build these complex biological structures. The results were ...
Medical Xpress / Blood test shows promise for detecting pancreatic cancer at its earliest stages
Researchers at City of Hope, one of the largest and most advanced cancer research and treatment organizations in the country, led the development of a new investigational blood test that could detect pancreatic cancer at ...
Phys.org / Without bacteria or chemicals: How methanol and formaldehyde form abiotically in nature
The biopolymer lignin—one of the most important carbon reservoirs in plants and soils—not only decays through fungi or bacteria but can also be chemically attacked by iron linked to reactive oxygen species, without the involvement ...
Phys.org / Biophysical model suggests how cells optimize information gathering without using too much energy
In both biological and engineered systems, cells and sensors must make sense of noisy, changing signals to function. However, collecting and using this information consumes valuable energy. A new study, published in Physical ...
Tech Xplore / AI imagines a harsher social world, expecting punishment where people expect inaction
Artificial intelligence (AI) systems, particularly the large language models (LLMs) that underpin ChatGPT and similar platforms, are remarkably skilled at answering queries about a wide range of topics. However, the extent ...
Phys.org / New species of 240-million-year-old prehistoric animal could reshape dinosaur origins timeline
A new prehistoric animal species from Tanzania dating to around 240 million years ago, during the Triassic period, has been described by an international team of researchers. Led by the University of Bristol, the new species, ...
Medical Xpress / HIV injections work better than tablets for young people, clinical trial finds
Young people living with HIV manage their condition better when their antiretroviral therapy is given by injections every eight weeks rather than daily tablets, according to results of a trial in Africa led by UCL (University ...
Phys.org / Snow, monsoons and oceans shift Earth's center of mass each year, satellite tracking shows
Seasonal changes redistribute enough water around Earth to shift the planet's center of mass back and forth by fractions of an inch relative to its geometric center. NASA scientists are on the case, tracking the oscillations ...
Phys.org / Motivational traits may help explain why some people report greater well-being
"People who are determined, passionate and believe in their ability to improve appear more likely to flourish and experience meaningful, engaging lives," says Professor Hermundur Sigmundsson at NTNU's Department of Psychology.
Phys.org / Nearly 50 'ghost galaxies' emerge around three hosts, challenging dwarf galaxy counts
Dwarf galaxies—with a mass equal to about a billion suns, but often considerably less—are the most abundant in the universe. However, because of their low luminosity, they are very difficult to detect. They have mostly been ...
Phys.org / Half-billion-year-old fossils rewrite the origin story of starfish
Scientists have discovered several 518-million-year-old fossils that reshape understanding of the origins of the animal group containing starfish. The fossils show that these animals ate using tentacles rather than passively ...
Phys.org / History is being rewritten at an archaeological site in Morocco. What the discovery of an ancient wall tells us
In the hills of northwestern Morocco, overlooking the river that gives the site its name, research at Oued Beht is bringing to light a previously unknown chapter of the region's past. The discovery of a substantial built ...
