Phys.org / When Americans migrate from violent states, the risk of future violence follows them
Americans who grow up in historically violent states may move to a safer state, but they remain far more likely to die violently, according to new research co-authored at the University of California, Berkeley.
Phys.org / Newly discovered star opens 'laboratory' for solving cosmic dust mystery
Seventy light-years from Earth, a star called Kappa Tucanae A harbors one of astronomy's most perplexing mysteries: dust so hot it glows at more than 1,000 degrees Fahrenheit, existing impossibly close to its host star, where ...
Phys.org / Crickets munch on microplastics—especially if they have a big mouth
To a human, microplastics are very small at less than 5 millimeters (mm) wide. But to an insect, microplastics might be the same size as the food they usually eat. Researchers reporting in the journal Environmental Science ...
Phys.org / Seeing physics as a mountain landscape for classification of nonlinear systems
Imagine standing on top of a mountain. From this vantage point, we can see picturesque valleys and majestic ridges below, and streams wind their way downhill. If a drop of rain falls somewhere on this terrain, gravity guides ...
Phys.org / X-ray laser offers new look at protein movement inside cells
At European XFEL, researchers have observed in detail how the vital iron protein ferritin makes its way in highly dense environments—with implications for medicine and nanotechnology.
Phys.org / Sounding the 6,000-year-old shell trumpets of Catalonia
Archaeologists have played shell trumpets from Neolithic Catalonia, revealing they were highly effective for long-distance communication and may have also been used as musical instruments.
Phys.org / Light-triggered nanoscale heating can control communication between nerve cells
Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, report the successful creation of artificial synaptic vesicles that can be remotely controlled by near-infrared (NIR) light. By embedding ...
Phys.org / First fertilizer: A chemical process that may have sparked life on Earth
University of Alberta geochemists have discovered a missing piece to one of the great mysteries of science—the origin of life on Earth.
Phys.org / Southern Annular Mode in most positive state in 1,000 years, review finds
A new review has revealed that the Southern Annular Mode (SAM), the Southern Hemisphere's most influential climate driver, is now in its most positive state in more than 1,000 years. If greenhouse gas emissions continue to ...
Phys.org / Adjustable DNA 'shield' can control timing and rate at which mRNA produces proteins in vivo
mRNA, widely known from the COVID-19 vaccine, is not actually a "therapeutic agent," but a technology that delivers the blueprint for functional proteins in the body and induces therapeutic effects. Recently, its application ...
Phys.org / Newly discovered viral enzymes act like molecular scissors to disable immune alarm signals
Viruses and their hosts—whether bacteria, animals, or humans—are locked in a constant evolutionary arms race. Cells evolve defenses against viral infection, viruses evolve ways around those defenses, and the cycle continues.
Phys.org / Define your dating goals: Study shows clarity is key to dating satisfaction
Single people who date without a clear understanding of what they are looking for in a relationship experience more loneliness and decreased life satisfaction, McGill researchers have found.
