Ultrathin nanotubes reach 1 nanometer, opening path to smaller electronics

Before testing new therapies in animals, researchers now have a more efficient starting point—lab-grown canine muscle cells that can help identify what works and what doesn't.

By integrating findings from 140 studies and nearly 66,000 individuals, researchers from the Biosocial team at the Max Planck Institute for Human Development in collaboration with Columbia University in New York have shown that lower socioeconomic status and exposure to discrimination are consistently associated with accelerated biological aging, measured in the epigenome.

To truly understand what an asteroid is made of, we need to send a probe to it. Remote sensing from ground-based telescopes, or even orbiting observatories, can only do so much. A new white paper submitted to the U.K. Space Agency's 2035 Space Frontiers program (available on the arXiv preprint server) pitches just such a mission architecture. Called the REndezvous Mission for Orbital Reconstruction of Asteroids (REMORA), the plan calls for a swarm of autonomous CubeSats to tag, track and charact

Most people have experienced a heat wave on land. But heat waves can strike in the ocean too. And as the planet continues to warm, marine heat waves are growing longer and deadlier, hurting the seafood supply that billions of people worldwide rely on for their food and livelihoods.
