Phys.org / Self‑replicating circular RNA persists in extreme environments: Insights from hot spring microbiomes
Although the genetic material of most living organisms is DNA, various self-replicating agents rely instead on RNA, including RNA viruses and viroids, which are infectious RNA molecules that are smaller and structurally simpler ...
Medical Xpress / COVID-19 may leave placental damage, but virus disappears after maternal recovery
A new Yale study published in JAMA Network Open finds that the virus that causes COVID-19 does not linger in placental tissue weeks to months after a pregnant woman recovers from infection—offering important reassurance for ...
Tech Xplore / AI can give as good as it gets—or better: The moral dilemma of combative chatbots
AI systems can "learn to seek revenge" because they are able to grasp reciprocating verbal violence when exposed to conflict, new research from Lancaster University shows. In short, AI can give as good as it gets and, eventually, ...
Phys.org / Cell membranes may store memories after electrical stimulation
The science of memories has been pursued and studied since the days of ancient Greece and Aristotle. Today, research conducted by Dima Bolmatov, assistant professor in the Department of Physics & Astronomy at Texas Tech University, ...
Phys.org / A laser inspired by black holes: Extreme physics recreated in the lab
Researchers from Bar-Ilan University have successfully recreated key features of black hole physics in a laboratory setting using an innovative optical system that mimics how black holes behave after violent cosmic events ...
Tech Xplore / 'Seeing clearly even in the fog'—a next-generation infrared image sensor for autonomous driving
Infrared sensors that detect the short-wave infrared (SWIR) region can clearly recognize objects not only during the day and at night, but also in fog or smoke, making them a key component of future intelligent technologies ...
Tech Xplore / YouTube offers deepfake detection to Hollywood
YouTube is offering Hollywood celebrities and entertainers a free detection tool to help combat their deepfakes, expanding the Google-owned video platform's efforts to guard against AI-driven impersonations.
Phys.org / Crabs' iconic sideways walk evolved from common ancestor, study suggests
Researchers have provided new insights into the evolutionary origin of sideways walking in crabs. Their study, published today as a Reviewed Preprint in eLife, presents the largest comparative dataset on crab locomotion to ...
Phys.org / Deep-rooted grass stores significantly more carbon, says new study
Soil biologist Eric Slessarev has some advice for conservationists, landscapers, and farmers with fallow fields: Go touch deep-rooted grass. Or better yet, go plant some. Slessarev, an assistant professor of ecology and evolutionary ...
Phys.org / New device aims to protect the Earth from Martian microbes
The possibility of life on other planets is one of the biggest mysteries in science. But what would happen if we actually found it? Our scientists are preparing for this possibility by helping to develop a new system that ...
Medical Xpress / A fresh take on the 'COVID Generation': How the pandemic may have changed young people for the better
At the peak of the pandemic in 2021, teenagers from Sackets Harbor, N.Y. got certified as ambulance drivers and took over running the local emergency medical service when the usual, much older, volunteers had to step away ...
Medical Xpress / Tourette's tics are not just motor misfires—an emotion-linked brain circuit may open a new treatment frontier
While tics have been considered to result from an aberrant function of the brain's motor cortex, a Kobe University mouse study has now discovered a connection to the brain's emotional functions. The result promises a new ...
