Tech Xplore / Metal foam front rails could make cars safer in collisions
A new study finds that composite metal foam (CMF) could significantly improve automobile safety during frontal collisions. Using computational models to run detailed simulations, researchers found that incorporating CMF into ...
Medical Xpress / Stress proteins actively sustain joint inflammation in osteoarthritis, study finds
Why do some joints remain chronically inflamed in osteoarthritis and other rheumatic diseases? Researchers have taken an important step toward answering this question. Their findings, published in the journal Cell Death & ...
Phys.org / Underwater meadows sustain millions in extreme poverty
A study provides the first large-scale empirical evidence that seagrass meadows act as a critical safety net for millions of coastal people living in extreme poverty across the Indo-Pacific.
Phys.org / Heavy water's atmospheric fingerprints boost weather forecasts for up to five days
Weather forecasts rely on many different kinds of data, including temperature, humidity and wind. For the first time, researchers, including those at the University of Tokyo, have demonstrated that a long-theorized improvement ...
Phys.org / Study reveals pupils most at risk of school suspension and what may help them
School suspensions are associated with a complex combination of socioeconomic disadvantage, special educational needs, peer relationships and students' experiences of school, according to new research from The University ...
Phys.org / Wrinkled or smooth? Cell growth mechanics determine shape of plant organs
When inner and outer cell layers of sepals—the leaf-like plant organs that cover and protect the flower bud before it opens—all grow upward, the organs stay smooth and uniformly stiff, which is optimal for the plant, according ...
Medical Xpress / More frequent cannabis use linked to poorer mental health
More frequent cannabis use is associated with fewer days of good mental health among adults, particularly men, according to a study co-authored by a University of Miami Business School professor.
Phys.org / What's in an 'O'? Unusual Greek spelling may unlock mystery of ring tied to Pontius Pilate
It's a small, simple ring made of copper alloy and engraved with a handful of Greek letters and the image of a pottery vessel. But its unremarkable appearance belies a remarkable history: The signet was likely connected in ...
Phys.org / AI-designed proteins enable a new generation of RNA transporters
RNA-based therapeutics use RNA as a blueprint that enables cells to produce specific proteins—including proteins that can precisely modify genes. For this to work, the RNA must reach the inside of the cell intact. Delivery ...
Phys.org / Surf's up: How the seafloor shapes breaking waves
A new study led by surfing scientists at the Scripps Institution of Oceanography at UC San Diego revealed the physical relationships underlying a pattern familiar to generations of surfers.
Phys.org / How stressed cells put the brakes on protein 'shipping'
Cells synthesize proteins in the endoplasmic reticulum (ER), and these proteins are transported to the Golgi apparatus for distribution to their ultimate destinations inside and outside the cell. The structures that transport ...
Phys.org / Pigment found in beets linked to plants' adaptation to harsh environments
The pigments that give beets their red color may have helped a major group of flowering plants repeatedly adapt to dry environments, setting the stage for the evolution of traits that allowed plants to adapt to some of the ...
