Phys.org / Shear flow in narrow channels sparks amyloid formation, experiments reveal
Many cars and not enough lanes is a recipe for traffic jams. Now, researchers from Japan show that even proteins can get backed up and start behaving poorly when too many try to squeeze too quickly through a small space.
Phys.org / MOF-coated catalyst converts CO₂ to CO nearly five times faster under ultrasonic vibration
Researchers at the University of Osaka have developed a catalyst that uses mechanical vibration to convert carbon dioxide (CO2) into carbon monoxide (CO), an important chemical feedstock. The catalyst consists of barium titanate ...

On Sunday, Aug. 30, the Nancy Grace Roman Space Telescope is expected to launch from NASA's Kennedy Space Center in Florida. The observatory will join the Hubble Space Telescope, launched in 1990, and the James Webb Space ...
Phys.org / Researchers reveal the unique 'tagging' mechanism that guides the sleeping brain in remembering key thoughts
Why do we remember certain moments while forgetting others? Every day, our minds are bombarded with thousands of pieces of information, yet our brains have a limited capacity to consolidate these experiences into lasting ...
Phys.org / Egypt's deserts were once home to a diverse shark community
During the Late Cretaceous period, parts of Egypt were covered in water. A new study, published in the journal Cretaceous Research, describes new evidence that this tropical sea was home to a diverse community of sharks. ...
Phys.org / XY or ZW? Gecko chromosomes reveal evolution's hidden playbook
Why do humans rely on XY chromosomes to determine sex, while birds use ZW—and many reptiles use neither, letting temperature decide instead? Sex determination is remarkably diverse across the animal kingdom. In genotypic ...
Medical Xpress / Pre-cancerous blood cells may fuel disease risk by prematurely aging the bone marrow
Precancerous blood cells can actively reshape their surroundings, prematurely aging cells in the bone marrow to create conditions that favor their own growth and potentially increase the risk of blood cancer, according to ...
Phys.org / The hidden physics behind the shape of rose thorns
Roses are known for their thorns, the sharp structures that can sting and prickle the skin. Thorns, botanically known as prickles, are thought to discourage animals from feeding on plants and may also help climbing roses ...
Medical Xpress / Male sex hormones may protect lungs from asthma by boosting nerve connections
The differences in male and female sex hormones are most evident during growth, puberty and reproduction, when they help shape how the body develops and functions. Beyond their more visible effects, these chemical messengers ...
Medical Xpress / Brain activity patterns may 'tag' experiences for later memory-making during sleep
The brain may "tag" experiences during learning to better consolidate memories of them during sleep, according to a study published Aug. 27 in the journal PLOS Biology by Dan Denis from the University of York, United Kingdom, ...
Phys.org / Wills, passwords, tricky conversations: What to do now to make your death easier for your family
Most of us don't like thinking about our own death. But there is a practical reason to do so: When you die, somebody else has to sort out what you leave behind.
