Phys.org / Shapeshifting gates guard the cell nucleus, challenging old ideas
An international study led by the University of Basel has discovered that nuclear pore complexes—tiny gateways in the nuclear membrane—are not rigid or gel-like as once thought. Their interiors are dynamically organized, ...
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.
Medical Xpress / Brain researchers draw cellular blueprint for how we think and feel
A new study from experts with Georgia State University has achieved a long-standing goal in neuroscience: showing how the brain's smallest components build the systems that shape thought, emotion and behavior.
Medical Xpress / Supplement trio shows promise in reversing autism-linked behaviors in mice
Researchers led by Tzyy-Nan Huang and Ming-Hui Lin from Academia Sinica in Taiwan report that a low-dose mixture of zinc, serine, and branch-chain amino acids can alleviate behavioral deficits in three different mouse models ...
Phys.org / Rapid weather shifts govern how plants influence climate and air quality, study finds
A new study shows that during drought, it's not how hot or how dry it is that determines gas emissions from plants—but how quickly conditions change. This discovery reshapes our understanding of the relationship between ...
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 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.
Tech Xplore / Laser-assisted 3D printing can fabricate free-standing thermoset-based electronics in seconds
Thermosets, such as epoxy and silicon rubbers, are a class of polymer (i.e., plastic) materials that harden permanently when they undergo a specific chemical reaction, known as "crosslinking." These materials are highly durable, ...
Phys.org / Spaceflight-tested menstrual cup offers choice on long missions
Eating from pouches, sleeping in a bag tied to the wall, using a vacuum-powered toilet: Basic processes of human life require scientifically tested solutions in space. It's the same for menstruation, a process female astronauts ...
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 / 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 ...
Medical Xpress / Hospital visits for hallucinogen use linked to six-fold higher risk of later mania
People who have received emergency or hospital care in Canada due to hallucinogen use have a six-fold increased risk of receiving care for mania in the next three years, according to a study published in PLOS Medicine by ...
