Medical Xpress / REM and deep sleep, not just total sleep time, associated with disease risk
Greater amounts of REM and deep sleep were associated with lower risks of dozens of diseases, and less than 5 hours of total sleep was associated with high disease risks, according to a new study published Sept. 17 in the ...
Phys.org / Disorder is key to tuning a high-temperature superconductor
Cornell physicists have discovered that minimizing disorder, not varying electron count, is the key factor for controlling superconductivity in the unique material iron selenide (FeSe), a new insight for understanding high-temperature ...
Phys.org / Microfluidic device simulates human tissue and offers an alternative to animal testing
Researchers at the Brazilian Center for Research in Energy and Materials (CNPEM) have developed microfluidic technology that can grow cells in three dimensions (3D). The goal is to conduct toxicity tests on new products by ...
Phys.org / Why global wind energy may stay steady even as storm tracks shift poleward
Understanding how wind changes in response to global warming is necessary for accurately modeling climate and weather, identifying risks to infrastructure, and assessing global wind power capacity.
Phys.org / Vapor-phase synthesis of MXenes could expand their technological applications
MXenes are two-dimensional nanomaterials first synthesized at Drexel University in 2011. They have been recognized by the International Union of Pure and Applied Chemistry as an emerging technology with "true potential to ...
Medical Xpress / Gestures influence the way our brains process grammar
Our hands may do more than complement what we say. They can also help our brains process grammar. In a new neuroimaging study published in PNAS, researchers from the Max Planck Institute for Psycholinguistics (MPI) in Nijmegen ...
Phys.org / NASA spacecraft discovers a huge new crater on the moon
Scientists have discovered a crater on the moon that's bigger than the Roman Colosseum and is the result of a powerful impact two years ago that initially went undetected.
Phys.org / Decoding the DNA switches behind gene regulation
Understanding gene regulation may be key to interpreting human disease genetics. Genes are regulated in part by stretches of DNA called enhancers, which define when, where and how strongly each gene is turned on. Mapping ...
Phys.org / Activated learning-and-memory protein forms growing molecular chains, imaging reveals
Researchers at the Nano Life Science Institute (WPI-NanoLSI) at Kanazawa University, Kyoto University, SOKENDAI and the National Institute for Physiological Sciences have revealed how CaMKIIα—a key brain protein involved ...
Phys.org / Webb measures extreme gas outflows from distant 'dead' galaxies
Astronomers using the James Webb Space Telescope have measured the most powerful gas outflow ever recorded from a "dead" galaxy outside our cosmic neighborhood and found that even outflows this extreme may not be enough to ...
Phys.org / Moles' wide-armed posture reshapes how their shoulder bones carry loads
While the scapula is the primary bone supporting the body in terrestrial quadrupedal mammals, an analysis of internal bone structure in underground moles (family Talpidae) showed a more important role for the clavicle.
Phys.org / Is dark matter 'natural?' Physicist puts the question to the test
Dark matter is one of the oldest open problems in physics. It makes up most of the matter in the universe and shapes how galaxies form and move, yet no one has ever directly detected it. Physicists have proposed dozens of ...
