Phys.org / El Nino is here and scientists fear it'll be big, bad and costly with heat, floods, droughts, fires
El Niño, Nature's chaotic climate agent, has formed in a warmed-up Pacific Ocean and is expected to grow to historic strength, meteorologists announced Thursday.
Phys.org / New cavity control strategy improves performance of blue vertical-cavity surface-emitting lasers
GaN-based vertical-cavity surface-emitting lasers (VCSELs) are promising for displays, sensing and optical communication, but improving efficiency remains challenging. Researchers have now shown that "cavity tuning," which ...
Tech Xplore / Asynchronous AI cuts computing energy by orders of magnitude while learning continuously
As artificial intelligence systems grow larger and more powerful, their energy demands are rising dramatically. But recent research from the University of Massachusetts Amherst published in Nature Communications suggests ...
Phys.org / Tea compound boosts seaweed hydrogel strength fivefold, while tuning adhesion and breakdown
Could wound healing dressings adhere better, and could drug delivery patches become more sophisticated? A KAIST research team has developed a technology that leverages natural ingredients derived from plants to increase the ...
Medical Xpress / Human traits beyond inherited genes can still leave a measurable imprint on your life, study shows
Our parents' genes, even the ones we didn't inherit, leave a measurable lasting imprint on our lives. An international team led by researchers at the Institute of Science and Technology Austria (ISTA) and the Norwegian Institute ...
Phys.org / Cosmic bombardment may have opened Earth's crust for prebiotic chemistry
Asteroids and planetesimals regularly bombarded Earth between about 4.6 billion and 3.5 billion years ago, during the Hadean and Archean eons. Because few rocks today are more than 4 billion years old, our understanding of ...
Phys.org / Indoor urban agriculture isn't necessarily low carbon, study shows
Growing lettuce indoors in Canadian cities can be as climate-friendly as conventional farming, but only in regions where electricity comes from renewable sources and is therefore low-carbon, according to a new McGill-led ...
Phys.org / Scientists uncover RNA's hidden role as protein chaperone
Proteins are how cells get work done. They carry out nearly every important cellular task, from ferrying messages to controlling which genes are turned on or off. And in order for proteins to perform their various roles, ...
Phys.org / Chloroplast map reveals 'missing link' in plant growth and solar energy
For decades, science has understood the basics of photosynthesis, the process by which plants turn sunlight into food. However, photosynthesis occurs on uniquely specialized membranes that we have only begun to understand. ...
Phys.org / Nature's 'master painters': Study reveals how damselflies break optical barriers to create saturated colors
Scientists at Ben-Gurion University of the Negev (BGU) have uncovered for the first time the "ingenious" biological strategies that allow blue-tailed damselflies to produce strikingly vivid, angle-independent colors. The ...
Medical Xpress / Chile's food warning labels and ad bans cut child obesity risk, analysis suggests
Chile's complementary set of policies targeting food products high in fat, salt and sugar plausibly reduces the risk of school-age children being overweight or having obesity, finds a study published in The Lancet.
Tech Xplore / Researchers discover hidden chip threats and a way to stop them
Every day, billions of people trust computer chips to protect their most sensitive information, ranging from banking passwords to national security secrets. But what if those chips were secretly compromised before they even ...
