Phys.org / ISS study identifies thresholds for muscle atrophy and fiber changes in reduced gravity
It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in near-zero gravity (microgravity) environments. However, the gravity threshold needed to maintain sufficient ...
Phys.org / Changing leafcutter ants' food reshapes their microbial gardens, scientists find
A colony of leafcutter ants is home to more than just one species. Each year, studies reveal new layers of complexity in these ecosystems, where various fungi and bacteria thrive alongside the ants, resulting in countless ...
Phys.org / Carbon nanotube 'black paint' absorbs terahertz radiation to cut 6G interference
Skoltech researchers and their colleagues from KTH Royal Institute of Technology, Sweden, have created an important building block for future 6G communication technology, which will make wireless data transfer at superior ...
Phys.org / Clearing circular RNA from cells extends lifespan, C. elegans study reveals
Cells in our bodies produce RNA based on genetic information stored in DNA, and RNA serves as a blueprint for making proteins. Researchers at KAIST have discovered a new phenomenon: Removing "circular RNA" that accumulates ...
Phys.org / The best places to look for alien life: Scientists identify 45 Earth-like worlds to explore for a 'Project Hail Mary'
If we're to find extraterrestrial life in the universe, astronomers have pinpointed the best places to look for it. They have identified just under 50 rocky worlds most likely to be habitable out of the more than 6,000 exoplanets ...
Phys.org / From free love to post-apocalyptic survival: A trend of redefining family has emerged
Chosen families are evolving but remain a cherished—and vital—lifeline for many. Mention "communal living" and the image that may spring to mind is the free-love, back-to-the-earth hippy communes of the 1960s, complete ...
Phys.org / 'Mini earthquakes' turn tiny chips into radio signal powerhouses
From GPS satellites to mobile networks, modern technology relies on ultra-precise radio signals. Engineers have long tried to generate them on chips using interactions between light and sound, but the effect was too weak. ...
Phys.org / Ultra-thin MoSe₂ grating traps infrared light in a 40-nanometer layer
Controlling light at the micro- and nanoscale opens up opportunities for a better understanding of the world and the development of technology. As modern electronics approaches the limits of its capabilities, photonics comes ...
Medical Xpress / High meat consumption linked to lower dementia risk in APOE4 carriers
Older people with a genetic risk of Alzheimer's disease did not experience the expected increase in cognitive decline and dementia risk if they consumed relatively large amounts of meat. This is shown in a new study from ...
Medical Xpress / Trends in youth mental health from 1990 to 2021 reveal a pandemic-era surge
Adolescence, the stage of development between childhood and adulthood, is characterized by many profound physical, mental, and emotional changes. During this critical stage, young people can experience various difficulties ...
Phys.org / Discrete time crystal acts as a usable sensor for weak magnetic oscillations
The bizarre properties of discrete time crystals could be harnessed to detect extremely subtle oscillations of magnetic fields, physicists in the US and Germany have revealed. Publishing their results in Nature Physics, a ...
Medical Xpress / New 'fishhook' bonds help T cells stick longer to prostate cancer cells
UCLA and Stanford Medicine researchers, in collaboration with scientists from the University of Utah and Columbia University, have engineered a new class of supercharged T cells that are stronger, longer-lasting, and more ...
