Astronomers witness the birth of a magnetar for the first time

A strange "chirping" signal from a distant supernova has revealed the birth of a magnetar, confirming that these incredibly magnetic neutron stars can power the universe's brightest stellar explosions. The discovery also marks the first time Einstein's general relativity has been used to explain the mechanics of a supernova.

5,000-year-old wolves found on remote island rewrite what we know about domestication

Scientists discovered ancient wolves on a tiny Baltic island where they could only have been brought by humans, suggesting an unexpectedly close relationship between people and wolves thousands of years ago. Evidence indicates the wolves were fed, possibly cared for, and may even have been managed or selectively bred long before modern ideas of domestication.

Record-breaking ocean drilling reveals why Japan's 2011 tsunami was so deadly

Scientists have uncovered a hidden weakness beneath the Pacific Ocean that helps explain why Japan’s catastrophic 2011 earthquake and tsunami became so devastating. By drilling deeper into the seafloor than ever before, researchers discovered a thin, slippery layer of ancient clay that allowed the massive rupture to race all the way to the ocean floor, triggering enormous seafloor movement and a powerful tsunami.

The Guardian view on gene-edited humans: darker uses must be acknowledged alongside medical ones | Editorial

Polling shows that the public supports this new technology, but the conversation must move beyond simple questions of safetyEver since Crispr-Cas9 gene-editing technology emerged in the early 2010s, ethical questions around genetically altered humans, so-called designer babies, have become increasingly urgent. There is already a worldwide legal prohibition. No country currently allows human germline editing (meaning genetic changes to an embryo that could also be passed on to its children), and

Scientists discover the deep sleep circuit that builds muscle, burns fat, and boosts the brain

Researchers have identified the brain circuitry that links deep sleep with the release of growth hormone, revealing how the two regulate each other. The newly discovered feedback loop helps explain why poor sleep can interfere with growth, muscle repair, fat metabolism, and brain function. Understanding this system could pave the way for new therapies for sleep disorders and diseases tied to metabolism and the brain, including Alzheimer's and Parkinson's.
