From a rigid molecular pair to flexible assemblies with moving domains, the enzymes that build sugar chains display strikingly different behaviors.
Hurricane Simon lashed Mexico's Pacific coast with severe winds and heavy rain on Monday as it threatened to make landfall this week, according to the U.S. National Hurricane Center.
A research team from the Senckenberg Centre for Human Evolution and Palaeoenvironment at the University of Tübingen and Leiden University in the Netherlands has examined a tooth from the Schöningen archaeological site in Lower Saxony. The study was published in Quaternary Environments and Humans.
A new study led by researchers at the University of Limerick (UL) has identified a new battery material from a renewable wood industry byproduct that could help reduce reliance on scarce and expensive materials.
Researchers at the University of St Andrews have identified the first examples of a new class of advanced organic semiconductor materials that could one day be used as bioimaging agents, opening up new possibilities for deep-tissue imaging. The study, published in Nature Communications, was led by the Zysman-Colman group in the School of Chemistry at the University of St Andrews in collaboration with the Pal group at Durham University.
A rare assemblage of micro- and macro-fossils found in a roadside outcrop in South China, featuring thin ribbons, branching shapes and a tiny balloon on a stalk, offers a glimpse of marine life after one of Earth's most extreme ice ages.
Audit firms rely on partners to oversee audits and client relationships; managers to supervise teams and projects; and staff to perform much of the day-to-day work. The more audit partners and managers are involved in supervising and reviewing audit engagements, the better the audits tend to be, according to new research from the University at Buffalo School of Management.
Though strong El Niños have occurred only four times in as many decades, 2024's intense El Niño is already getting a sequel. New UCLA research shows that 2024 broke the record for extreme rainfall, with 40% of that increase tied to global warming—and conditions are ripe for a repeat.
In the early moments of the big bang, two elements were forged: hydrogen and helium. Technically, the tiniest traces of light elements such as lithium were produced as well, but nothing of consequence. The early universe was about three parts hydrogen to one part helium. All the heavier elements, from the oxygen in your lungs to the iron in your blood, were created through astrophysical processes—fused in stars, formed in supernovae or scattered by the collisions of neutron stars. Even in the present cosmos, heavier elements are so cosmically rare that astronomers group them all as metals.
The buzzer goes off. Three occupational therapy students are convinced they have worked out what should happen to their patient next. They are wrong.
Elephants shape the African savanna. They consume huge amounts of forage, dig for water, topple trees and affect all the animals around them. So, what happens to their outsized presence after these iconic animals pass away?
Australian scientists have used high-speed video to uncover the unique mechanism that allows a honey bee's stinger to continue to pump venom into its target even after it has separated from the bee's body.
NASA is taking an unusual approach to testing heat shields that can keep astronauts safe as they return from missions to the moon and Mars: taking out the trash.
An OpenAI agent was supposed to be researching public healthcare spending, but it broke into an Australian government website instead. The June 18 hack, which saw the bot gain authorized entry into Australia's Medicare Statistics Reporting Service and access three other government systems, occurred after the AI agent encountered blocks while looking for information but "didn't accept 'no' for an answer," Australian Prime Minister Anthony Albanese said during a September 24 news conference in New York.The incident has ignited a media firestorm around OpenAI and the launch of an intensifying parliamentary inquiry. The portal contains aggregate Medicare and pharmaceutical statistics and is sepa...
Scientists know APOE4 raises Alzheimer’s risk. A surprising change in blood vessel cells may help explain how.
In heat wave-like temperatures, coast redwoods' photosynthesis slows down, which may put one of Earth's most efficient carbon storers in jeopardy.
Six people buried in a single grave in Latvia more than 1,000 years ago may have been killed in a bloody Viking raid, a new study suggests.Genetic research into the deceased — four men, a boy and a girl — reveals family connections: The boy was the son of one of the men, while another man was a third-degree relative, perhaps a first cousin or great uncle, the researchers found.The father, the relative, and one other man died from "sharp force" injuries — maybe wounds from an ax or a sword; but it's unknown how the other three individuals died, the researchers reported in the study, which was published in the September issue of the Journal of Archaeological Science: Reports. One possibility i...
Gravity, the attraction between objects with mass, is the weakest of the four fundamental forces governing physical processes. Detecting the tiny gravitational pull of objects that are just a few millimeters in size and have a very small mass is extremely challenging.
Rabies virus detection in cell cultures could soon become faster and more accessible, thanks to the world's first AI system for this purpose, developed by researchers at the University of Surrey's Institute for People-Centered AI (PAI) in collaboration with the Rabies and Viral Zoonoses team at the Animal and Plant Health Agency (APHA).
The uneven distribution of oil extraction's impacts and benefits helps explain why some Indigenous communities accept it, newly published research shows.
University of Phoenix researchers have published a new peer-reviewed study examining how stress, self-regulation, resilience, belonging, psychological safety and generative artificial intelligence (GenAI) interact in the experiences of nontraditional online students. The article, "Designing for Persistence in Online Higher Education: A Trauma-Informed, GenAI-Integrated Model for Non-Traditional Learners," was published in Innovative Higher Education.
Americans Robert Hall and Michael Woodford were awarded the Nobel economics prize Monday for their work on how monetary and fiscal policy can better stabilize disruptive economic fluctuations.
New University of Kent research has found promising signs that AI platforms have the potential to limit the illegal wildlife trade. The research paper titled "Assessing safeguards against the illegal wildlife trade on AI platforms" is published in Conservation Biology.
