Lab-grown canine muscle cells offer solution for early therapeutic testing‎

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.

Faster biological aging consistently linked to poverty and discrimination‎

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.

Meet REMORA: The autonomous space fleet built to tag and track asteroids‎

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 characterize multiple near-Earth asteroids.

Solar geoengineering could shield up to 75% of oceans from heat waves‎

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.

Gulf Stream shifted north during 12,900-year-old cold snap, first direct evidence shows‎

During an abrupt global cold snap nearly 13,000 years ago, the Gulf Stream ocean current shifted farther north, temporarily disrupting eastern Canada's oceanic ecosystems, a process that could happen again as the climate changes, a new study by UCL researchers finds.

Jurassic viral gene may have helped apple snails start laying eggs on land‎

Pomacea canaliculata, commonly known as the apple snail, is a pest commonly found in Hong Kong's wetlands and farmlands. It feeds on aquatic plants and produces toxic pink egg masses resembling miniature grapes that adhere to plants or stone bunds. It is listed by the International Union for Conservation of Nature (IUCN) among 100 of the World's Worst Invasive Alien Species.
