Phys.org / Noisy bubbles hinder ultrasound-boosted chemical reactions, sonochemistry model shows
Ultrasound is a powerful way to drive chemical reactions. When high-frequency sound waves pass through a liquid, tiny bubbles form and then violently collapse in a process called acoustic cavitation. During this collapse, ...
Phys.org / A new take on interpreting chemical bond analysis in solids
Researchers from Skoltech, SberUniversity, the M.N. Mikheev Institute of Metal Physics of UB RAS and Ural Federal University have published a review of a novel approach to interpreting chemical bonding in solids. The method ...
Phys.org / Venus's polygonal plains could point to a watery past
Venus may be overwhelmingly inhospitable today, but many planetary scientists believe that it wasn't always this way. Billions of years ago, some observational evidence suggested that our planetary neighbor may have looked ...
Tech Xplore / Human-aware robots adapt to partners, reducing back strain during team lifting
When people work in pairs or teams, they can often solve a wider range of problems, completing some tasks faster and more efficiently than they would alone. To assist users similarly to how other humans would, robots should ...
Medical Xpress / Why laughter can trigger sudden muscle weakness in people with narcolepsy
Narcolepsy is a chronic neurological condition characterized by disruptions in the regulation of sleep-wake cycles. People with this condition often experience extreme sleepiness during the day and, in some cases, a sudden ...
Science X / HIV's hidden history: New study reveals much deeper roots stretching back millions of years
Researchers used to think that HIV and its relatives were pretty recent things, maybe only a few hundred years old. But a growing body of evidence now suggests their history is far more ancient, with viruses closely related ...
Medical Xpress / Patients with IBD face elevated risk of psychiatric disorders
Patients with inflammatory bowel disease (IBD) face a significantly higher risk of psychiatric disorders starting two to three years before diagnosis and lasting up to a decade afterward, according to a nationwide study published ...
Medical Xpress / Your bedroom could be the unhealthiest room in your home
Close the door, shut the windows and turn up the heat, and you have all the ingredients for a sick bedroom in your home—and you spend about eight hours there every night.
Phys.org / Total eclipse gives scientists chance to probe sun's mysteries
Scientists plan to use a total solar eclipse that will be visible in Spain next week as a rare chance to learn more about the stormy, unpredictable nature of our star.
Phys.org / Bird flu decimated South America's marine mammals. What can Australia do differently?
Australia is now confronting an outbreak of a deadly bird flu strain. As of Monday, the highly pathogenic H5N1 virus had been detected in 78 wild birds across mainland Australia. Until now, there had been no evidence of a ...
Tech Xplore / Waste heat becomes cooling energy: Research team develops next-generation heat pump system
A next-generation heat pump system that can provide cooling using low-temperature waste heat of approximately 40°C (104°F) from factories and data centers has been developed. Unlike conventional air conditioning systems, ...
Medical Xpress / Aerobic fitness may be a teller of some brain health, study suggests
Look at a group of kids, and you're going to see many different shapes and sizes.
