9+ mon, 4+ week ago (416+ words) This deep-sea polar worm looks like it can't decide if it's dressed for a glitzy party or a gruesome massacre. Name: Antarctic scale worm (Eulagisca gigantea) Where it lives: Below 1,640 (500 meters) deep in Antarctica's Southern Ocean What it eats: Unknown. Probably other animals and/or organic debris. Why it's awesome: With their shimmering golden coats, these worms almost look glamorous " until you see their horrifying jaws, which resemble the mouth of the xenomorph from "Alien." The worms are named after the scales (known as elytra) that cover their bodies. These scales look a bit like human teeth, adding to the worms' dazzling-yet-gruesome appearance. Growing up to 8 inches (20 centimeters) long, Antarctic scale worms are a type of ocean-dwelling polychaete, or bristle worm (polychaete is Latin for "many bristles"). Related to earthworms and leeches, there are over 8,000 named polychaete species. They have…...

3+ mon, 1+ day ago (792+ words) "Biological aging tests," also called aging clocks, can predict your risk of age-related disease, disability, early mortality and more " but are they ready for prime time? If you want to know your chronological age, simply count the candles on your next birthday cake. Calculating your biological age, though, is a little more complicated. Scientists have devised a number of "clocks" aimed at determining people's biological ages. Here's how they work and why they might be useful. Think of a battery: New batteries start at 100% capacity, in terms of their ability to reliably hold a charge, but that capacity drops over time as the battery cycles on and off and powers devices. Biological age is a similar concept of capacity, and the tools researchers and clinicians use to measure your capacity are known as aging clocks, also known as "omic clocks…...

2+ mon, 3+ week ago (483+ words) Stem cells age faster and become functionally exhausted in low Earth orbit, making crewed long-duration space travel even more challenging. Human stem cells get worn out and age much faster in space, a new study has found, which is a problem for anyone hoping to take a long trip through our solar system. Scientists used artificial intelligence (AI) to track changes to stem cells delivered by SpaceX resupply missions to the International Space Station (ISS). Up in space, the stem cells lost some of their ability to generate new cells, became more susceptible to DNA damage and aged faster, according to a statement released by the researchers. The study's findings, published Sep. 4 in the journal Cell Stem Cell, build on previous space health research that highlight the challenges of putting people in space for prolonged periods of time " something humanity…...

This week's science news has been dominated by medical marvels, with the announcement of a breakthrough gene therapy that has treated Huntington's disease for the first time. The new therapy introduced a new gene into cells in the two parts of the brain hit hardest by the disease to slow its progression by 75%, marking a remarkable first in the field. And while the treatment remains in clinical trials, the researchers have begun the application process to get it approved in the U.S. and then Europe. Elsewhere, we reported on the intriguing and troubling links between daylight saving time and strokes in a study which argues for abandoning biannual clock switching altogether.

3+ mon, 1+ week ago (475+ words) Keratin extracted from sheep wool has been found to help protect human teeth. It could be coming to your dentist's office soon. Dental treatments from sheep's wool and other hair could be used to coat teeth to repair enamel and prevent tooth decay, according to a new study. After extracting keratin " a protein found in hair, skin and fingernails " from wool and applying it to teeth, scientists found that the substance formed a protective crystal-like coating that mimicked natural tooth enamel. The finding could support sustainable, low-cost treatments for early tooth decay within the next two to three years, according to the researchers.They reported their findings August 12 in the journal Advanced Healthcare Materials. Untreated tooth decay is the world's most common oral health condition, affecting some 2 billion people worldwide. Over time, acidic foods, poor oral hygiene, and everyday wear…...

9+ mon, 4+ week ago (456+ words) A new smart fabric converts light into heat and can raise temperatures by more than 54 degrees Fahrenheit (30 degrees Celsius) after just 10 minutes in the sun. Scientists have invented a smart fabric that converts light into heat and can raise temperatures by more than 54 degrees Fahrenheit (30 degrees Celsius) after just 10 minutes in the sun. The new material could be used in clothing designed for very cold temperatures. Specialized nanoparticles that absorb sunlight and convert it to heat are embedded within the new material, which was described late last year in the journal Advanced Composites and Hybrid Materials. At the same time, temperature-responsive dyes incorporated into the fibers reversibly change color, allowing users to visually monitor temperature fluctuations. For years, scientists have designed wearable heaters to help maintain a comfortable body temperature in cold environments. Such fabrics could be used in mountain…...
