Medical Xpress / These shoes are best for hip and knee arthritis, according to science
People with hip and knee osteoarthritis are advised to wear "appropriate footwear" to minimize their pain. Does that mean heels are out? Does it matter if you wear runners or something a little stiffer? How about using insoles?
Phys.org / Animal muscles inspire biomaterial design for agriculture, fabrics and medicine
Natural muscle fibers are made up of spring-like proteins that can contract and stretch without losing their original form, dissipate mechanical energy as heat and maintain incredible tensile strength for all sorts of physical ...
Phys.org / Near-infrared study finds no clear counterpart to mysterious gamma-ray source
Spanish astronomers have conducted a near-infrared study of an ultra-high energy gamma-ray source designated LHAASO J2108+5157. The new study, published February 11 on the arXiv preprint server, tries to unravel the mysterious ...
Phys.org / Symbiotic bacteria in planthoppers break record for smallest non-organelle genome ever found
Many insects rely on heritable bacterial endosymbionts for essential nutrients that they cannot get through their diet. A new study, published in Nature Communications, indicates that the genomes of these symbiotic bacteria ...
Phys.org / Auroras on Ganymede and Earth share striking similarities
New observations of Ganymede reveal a striking similarity between the auroras on the largest moon in the solar system and those on Earth. The international team of astrophysicists, led by researchers from the University of ...
Phys.org / Living tissues are shaped by self-propelled topological defects, biophysicists find
With a new mathematical model, a team of biophysicists has revealed fresh insights into how biological tissues are shaped by the active motion of structural imperfections known as "topological defects." Published in Physical ...
Phys.org / Tuning in to fluorescence to farm smarter: Monitoring plant light use saves indoor farm energy costs
Plant owners with a so-called green thumb often seem to have a more finely tuned sense of what their plants need than the rest of us. A new "smart lighting" system for indoor vertical farms grants this ability on a facility-wide ...
Phys.org / Quantum entanglement could link distant telescopes for sharper images
To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, entails comparing the ...
Phys.org / Human activity is making the Arctic's waters louder
Climate change is having a profound impact on the Arctic. We know that the region is warming significantly faster than the global average, resulting in the melting of sea ice and disrupted habitats.
Medical Xpress / Rising temperature may shift sex ratios at birth, analysis of five million births finds
"Temperature and sex ratios at birth," a new study led by researchers at the Department of Sociology at the University of Oxford and published in Proceedings of the National Academy of Sciences, provides new evidence that ...
Medical Xpress / New 'liver-on-a-chip' device could make drug safety testing more reliable
Creating a drug that might help treat or cure a health condition in humans is a long, complex process. After developing a candidate drug that shows potential—a process that, in and of itself, can take decades—scientists ...
Medical Xpress / Historical trends in U.S. heroin use: Initiation after 2000 differs from earlier patterns
The production, distribution, and consumption of illegal opioids create problems for public health and safety in many countries. Overdose rates are particularly high in Canada and the United States, which experienced three ...
