Bacteria Feed on Toxic and Persistent PFAS Chemicals

Scientists have discovered a bacterium that can break down toxic "forever chemicals" DepositphotosThe so-called "forever chemicals" (PFAS) are increasingly present in the environment, food, drinking water, and even our bodies. However, researchers may have found a new solution to this problem: a bacterium capable of consuming these compounds and their toxic byproducts.Per- and polyfluoroalkyl substances...

An experimental treatment has shown excellent results in mice with the disease and uses a natural substance produced by beneficial gut bacteria.Understanding VitiligoVitiligo is an autoimmune condition that destroys melanocytes, the cells responsible for producing melanin, the pigment that gives skin its...

Enigmatic Blue Tree Rings Uncover History’s Harshest Summers

Blue rings visible in one of the tree samples. (Pawel Matulewski/Liliana Siekacz)A simple blue stain may unlock trees’ memories of cold summers and volcanic winters, offering scientists a precise new tool to reconstruct ancient climates through timber anatomy.By combining the biological stains safranin and astra blue, researchers can highlight areas with low lignin, a compound...

Scientists expected a cooldown after El Niño peaked in early 2024, but extreme heat persists, fueling debate over additional warming factors.Every fraction of a degree...

Claim That ‘2-Degree Target Is Dead’ Sparks Debate on Climate Scenarios

Credit: PixabayKeeping global warming under 2°C—the fallback goal of the Paris Agreement—is now "impossible," according to a controversial new study by prominent climatologist James Hansen and his team. Published in Environment: Science and Policy for Sustainable Development, the paper argues that Earth's climate is more sensitive to greenhouse gas emissions than previously thought.Adding to...

Apple’s Pixar-Style Lamp-Bot Showcases the Friendly Side of Machines

Apple's lamp-bot can depict joy and sadness, and even do a little danceAppleLuxo Jr. has been a charming presence in every Pixar film since 1995, when the animated desk lamp first hopped onto the screen, playfully stomping on the studio's logo in the opening credits. This iconic character has now inspired Apple researchers to...

Octopuses Have a Hidden Sex Chromosome That Predates Dinosaurs

Credit: PixabayUniversity of Oregon researchers have discovered a sex chromosome in the California two-spot octopus that likely dates back 480 million years—long before octopuses and nautiluses diverged. This makes it one of the oldest known animal sex chromosomes.The finding confirms that octopuses and other cephalopods, including squid and nautiluses, use chromosomes to determine sex,...

Watch: Scientists Create the World’s First Lab-Grown Kangaroo Embryo

Marsupials, like kangaroos, give birth to premature offspring that then develop in the mother's pouchDepositphotosFor the first time, scientists have successfully created kangaroo embryos using in-vitro fertilization (IVF), marking a significant breakthrough in efforts to replicate this process across hundreds of marsupial species increasingly at risk of extinction.A research team from the University of...
