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 / Most Americans worried about brain health, but few know how to protect it
Nearly all Americans are worried about their brain health as they age, ranking as important or more so than their physical health, a new Alzheimer's Association report says.
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, ...
Tech Xplore / Perovskite solar cells reach 26.61% certified efficiency with cesium-doping strategy
Solar cells, devices that convert sunlight into electricity, are now widely used in many countries. While most existing solar cells are based on silicon, energy engineers have been working on other devices made of so-called ...
Medical Xpress / New cellular target prevents hepatitis E infection
An international team of researchers has identified a promising new approach for treating infections with the Hepatitis E virus (HEV). At the center of the study is the drug Apilimod, which specifically blocks the entry of ...
Tech Xplore / Researchers develop navigation system for underground rescue teams
Operations underground, for example in underground stations, tunnels or mines, are risky and difficult for rescue teams. This is especially true if the technical infrastructure has collapsed due to explosions or fire, and ...
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 / Astronomers precisely date rare brown dwarf companion, offering new test for how these objects cool
Astronomers at the University of Hawaiʻi have precisely measured the age of a nearby sun-like star and its unusual companion, known as a brown dwarf, an object that falls between a planet and a star. The discovery offers ...
Phys.org / Legal categories for animals still divide—and limit—animal rights
The relationships human societies have with animals aren't fixed, but vary according to era, culture, territory and customs.
Medical Xpress / New targeted therapy shows promise against aggressive childhood and adult cancers
Researchers at the University of British Columbia Faculty of Medicine have developed a new targeted cancer therapy that can precisely seek out and destroy tumor cells—showing strong results in preclinical studies that bring ...
Medical Xpress / A hidden DNA region helps drive frailty, exposing brain and immune links that reshape aging risk
Researchers at McMaster University have identified, for the first time, a novel region of DNA and two associated genes connected to frailty, offering neurological and immune-related insights that might help explain why some ...
