Phys.org / Iron, sulfur and purple light unlock greener carbon-carbon bond formation
Much of organic chemistry, including the type used to create and alter medicinal drugs, relies on modifying carbon bonds. Rice University's Julian West has been developing a less expensive, faster and more environmentally ...
Phys.org / The Mediterranean is getting warmer and saltier at an ever-faster pace—even thousands of meters below the surface
Across its basins and thousands of meters down, the Mediterranean Sea is getting warmer and saltier. Now, a new study finds it is also doing so at an increasingly rapid pace. The speedup is largest in the central and eastern ...
Phys.org / Global database reveals hidden diversity and potential of deep-sea microbes
The ocean's aphotic zone—the dark, high-pressure region below the surface, where sunlight cannot reach—is home to a vast wealth of microbial life. Yet scientists know relatively little about the genetic makeup, growth and ...
Phys.org / Hedgehog coronaviruses may threaten cats more than humans, new study finds
Washington State University researchers have discovered how a group of coronaviruses circulating in hedgehogs invades host cells, a key to understanding their potential to jump between species and their risk of causing a ...
Phys.org / Insect remains reveal Indigenous burial practices in the Canary Islands
Archaeologists have analyzed insect remains preserved in the 7th to 9th centuries AD funerary cave of Cruz de la Esquina, Gran Canaria, and found that it was used by the island's Indigenous people for food storage before ...
Phys.org / Ice Age carvers used mammoth tusk patterns to create unique art, study finds
Intricate designs engraved across the surface of 18,000-year-old female figurines carved from mammoth ivory were inspired by the distinctive growth patterns visible in the tusks, a new study published in the journal npj Heritage ...
Phys.org / Deep ocean, familiar trash: Plastic waste found alongside possible new species
It's no secret that plastic and other human trash are a problem for marine life, but our understanding has long focused on the ocean's surface. As described in a study published in PLOS One, a more complete picture is coming ...
Phys.org / Speeding glaciers drive half a century of polar ice loss
The longest satellite record ever assembled shows that Greenland and Antarctica have lost 11.3 trillion metric tons of ice since the 1970s, raising global sea level by more than 3 centimeters (1.2 inches)—and that most of ...
Phys.org / Brazilian sedge reproduces sexually but without DNA reshuffling, producing genetic clones
Sexual reproduction usually reshuffles genetic information, creating offspring that differ from their parents. But one small plant takes an unexpected route. In a new study published in Nature, an international team led by ...
Phys.org / Engineers solve puzzle of Arctic sea ice movement
Arctic sea ice moves and spreads in ways that wind alone cannot explain. A new UC Riverside-led study finds that collisions between individual pieces of ice provide a surprisingly simple explanation for these movements, potentially ...
Phys.org / AI struggles to decipher 'animal language' because sound doesn't equal meaning, experts say
In recent years, numerous attempts have been made to use artificial intelligence to decipher the communication of bats, whales, birds and other animals. However, a new study led by a team of researchers from Tel Aviv University ...
Phys.org / Dual findings reveal how to control coherence in plasmonic nanolasers
Researchers at the University of Eastern Finland have uncovered two complementary mechanisms that govern coherence in miniaturized lasers composed of metallic nanoparticle arrays incorporated into an optical gain material, ...
