In an unexpected twist, metal-rich nodules found on the seafloor are generating oxygen, new research suggests. This meager but steady supply of the vital gas may help support seafloor ecosystems in areas currently targeted for deep-sea mining, scientists say. Scientists have long presumed that much of the dissolved oxygen in the deep sea was transported … Read more
Menstruation can be messy and uncomfortable, often due to leaky pads, tampons and cups. A new alginate-based powder may solve that problem. The material, which solidifies menstrual blood by turning it into a gel mixture, could reduce leakage in period products without compromising capacity, researchers report July 10 in Matter. Our paper is a proof … Read more
For the first time, astronomers have spotted a middleweight black hole in the nearby universe. The discovery could help solve the riddle of how even heftier black holes form and grow up with their host galaxies. The black hole, which sits about 16,000 light-years from Earth in the center of star cluster Omega Centauri, is … Read more
In the quest to build a quantum internet, scientists are putting their memories to the test. Quantum memories, that is. Quantum memories are devices that store fragile information in the realm of the very small. Theyre an essential component for scientists vision of quantum networks that could allow new types of communication, from ultra-secure messaging to … Read more
A mind-bending parasite may one day deliver drugs to the brain. Toxoplasma gondii is a single-celled parasite that famously makes mice lose their fear of cats, but also can cause deadly foodborne illnesses (SN: 1/14/20). Now, researchers have engineered the parasite to deliver large therapeutic proteins to the brains of mice and into human brain … Read more
In the science-fiction series Dune, the desert-dwelling Fremen of the arid planet Arrakis recycle their bodys moisture using specially designed outfits called stillsuits. Inspired by such imaginings, a new prototype spacesuit converts astronauts urine into drinkable water, researchers report July 12 in Frontiers in Space Technology. Ive been a fan of the Dune series for … Read more
In real life, laws are broken all the time. Besides your everyday criminals, there are scammers and fraudsters, politicians and mobsters, corporations and nations that regard laws as suggestions rather than restrictions. Its not that way in physics. For centuries, physicists have been identifying laws of nature that are invariably unbreakable. Those laws govern matter, … Read more
People with advanced cancers often feel like their bodies are wasting away. Thats because of cachexia, a condition in which impaired metabolism leads to muscle wasting and drastic weight loss (SN: 4/15/15). A new study in mice hints at a way to reverse the condition. Blocking the activity in the brain of an immune protein … Read more
A chemical element thats not even in H2O sulfur is the reason Earth first got its water, a new study finds, bolstering a similar claim made a year ago. The discovery means our planet was born with all it needed to create its own water and so did not have to receive it from elsewhere. … Read more
Forever chemicals are everywhere. Theyre in school uniforms, food packaging, cosmetics and personal care products (SNE: 11/18/22; SN: 6/4/19; SN: 6/15/21). They seep into our food and drinking water. And now new research suggests that some can move through the skin, posing yet another avenue through which humans are intimately exposed to these chemicals, which … Read more
