Phys.org / Study advocates cross-tier traceability to improve food safety
The Hong Kong SAR imports more than 90% of its food, and it can be very difficult, when food safety incidents occur, to trace the source across a complex supply chain. Prof. Leng Mingming, dean of the Faculty of Business ...
Phys.org / Digital twin predicts Alaska permafrost changes using real-time sensors and AI
Communities around the world have adapted to live on the year-round frozen soil of frigid environments, such as in the Arctic. However, rising temperatures have introduced a new challenge: What happens when the ground under ...
Medical Xpress / Study finds ~15 percent of U.S. pregnant women report drinking in past 30 days
From 2021 to 2024, 15.2% of U.S. pregnant women reported drinking alcohol in the past 30 days, according to research published in the U.S. Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report.
Phys.org / How the invention of glassblowing changed everyday life in ancient Rome
We see glass objects every day and often don't think much about them. Mass-produced glass has become so cheap we barely think about the things it allows us to do.
Medical Xpress / Could seeing themselves in a mirror help babies copy others?
A new study has assessed whether exposure to their own reflection influences the development of facial mimicry, a process associated with empathy and emotion recognition, in 4-month-old infants. The results showed that infants ...
Phys.org / Benzene reaction may explain how DNA and RNA building blocks formed on early Earth
Caltech researchers have identified a novel chemical reaction that could explain the formation of the building blocks of DNA and RNA, the molecules that encode all of life's functions. The work is an important step toward ...
Tech Xplore / Liquid cooling technology for semiconductor chips is 10 times more efficient than previous record
AI data centers are power-hungry. Not only do artificial intelligence computations consume enormous amounts of electricity, but a significant amount of energy is also required to cool the semiconductor chips that heat up ...
Phys.org / A handful of teeth may rewrite the story of marsupial evolution
Researchers have found evidence of a previously unknown branch of the marsupial family tree, a discovery that could reshape our understanding of how Australia's unique mammals evolved. Published in the Journal of Paleontology, ...
Phys.org / Chandra reveals flickering supernova remnants in M83 over 14 years
The aftermath of a supernova, a stellar explosion, is usually a slowly fading cloud of hot gas. So when astronomers pointed NASA's Chandra X-ray Observatory at the nearby galaxy Messier 83 (M83), they did not expect to find ...
Phys.org / A cornerstone of Milky Way history may need rewriting with evidence of multiple ancient mergers
Astronomers may have uncovered new details about one of the Milky Way's most important ancient collisions. Using data from the Dark Energy Spectroscopic Instrument (DESI) and a new clustering algorithm, researchers have found ...
Phys.org / Global data declaration targets illegal fishing
Fifteen countries signed a global declaration Wednesday aimed at combating illegal and destructive fishing with better data.
Dialog / When less is more: Scaling law explains why ultrathin materials get stronger as they get thinner
One of the most fascinating aspects of physics is that nature often behaves in ways that seem completely counterintuitive. A good example comes from ultrathin materials. If I take a sheet of material and make it thinner ...
