How do water and hydrogen interact in planetary evolution? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a | Space
In a social media post on Friday, Elon Musk said his startup xAI has acquired his social media company X.
Researchers have developed a tiny magnetic robot that can take 3D scans from deep within the body and could revolutionise early cancer detection.
The team, led by engineers from the University of Leeds, says this is the first time high-resolution three-dimensional ultrasound images taken from a probe deep inside the gastrointestinal tract, or gut, have been generated.
It paves the way to transforming the diagnosis and treatment of several forms of cancer by enabling ‘virtual biopsies’ – noninvasive scans that provide immediate diagnostic data. These scans allow doctors to detect, stage, and potentially treat lesions in a single procedure, eliminating the need for physical biopsies.
Wenzhou Medical University and collaborating institutions have identified a population of human neural retinal stem-like cells able to regenerate retinal tissue and support visual recovery.
Vision loss caused by retinal degeneration affects millions worldwide. Conditions such as retinitis pigmentosa and age-related macular degeneration involve the irreversible loss of light-sensitive neural cells in the retina. While current treatments may slow progression, they do not replace damaged tissue.
For decades, scientists have explored whether stem cells could be used to regenerate the retina, but the existence of true retinal stem cells in humans has remained uncertain. In fish and amphibians, the outer edge of the retina houses stem cells that regenerate tissue continuously. Whether a comparable system exists in the human eye has been debated for more than two decades.
Well done Gaia & crew. [ https://www.spacedaily.com/reports/Star-mapping_space_telesc…t_999.html](https://www.spacedaily.com/reports/Star-mapping_space_telesc…t_999.html)
After more than a decade mapping out our home galaxy, the Gaia space telescope was powered down and sent into “retirement orbit” around the Sun on Thursday, the European Space Agency said.
Since launching in 2013, the telescope has been charting the positions, motion and properties of nearly two billion stars to create a vast map of the Milky Way, revealing many secrets of the cosmos along the way, the ESA said in a statement.
Gaia uncovered evidence of massive galaxies slamming into each other, identified vast clusters of stars, helped discover new exoplanets and mapped millions of galaxies and blazing galactic monsters called quasars.
After 25 years of smashing gold nuclei together at light speeds, Brookhaven National Laboratory’s Relativistic Heavy Ion Collider is hanging up its boots—erm, superconducting magnets.
The collider’s final run—its 25th—kicked off this week on Long Island, in a swan song for the venerable collider that will be succeeded—in fact, transformed into—Brookhaven Lab’s Electron-Ion Collider (EIC). Over the course of 2025, RHIC physicists will complete data collection on quark-gluon plasma, the soup of particles that existed in the earliest days of the universe.
“The original idea behind RHIC was to create, for the first time on Earth, a state of matter that existed in the universe a few microseconds after the Big Bang: the quark-gluon plasma, and we did,” said James Dunlop, the associate department chair for nuclear physics at Brookhaven Lab, in a call with Gizmodo. “That’s one of the big legacies—that we actually created it—but the more interesting thing is that its properties were quite different from what we’d expected them to be.”
Fans of Studio Ghibli, the famed Japanese animation studio behind “Spirited Away” and other beloved movies, were delighted this week when a new version of ChatGPT let them transform popular internet memes or personal photos into the distinct style of Ghibli founder Hayao Miyazaki.
A team of MIT researchers recently created the first synthetic muscle actuator that can flex in multiple directions. This study opens the door for more capable soft robots and other advanced medical breakthroughs. Here’s how the team utilized a new 3D printing method, alongside specially made stamps, to grow synthetic muscles in the lab that can replicate the real thing.
Understanding Muscle Architecture and Movement
To understand why you can’t just make a motor that does what a muscle does, you first need to look at how your body operates. When you move your hand, there is a lot more going on than just your muscles pulling in a single direction. Many multidirectional skeletal muscle fibers form intricate patterns and are mounted at angles to produce the exact motions of the human body.
Our machines will be smart enough and eventually we will through intelligence enhancement.
For over a century, Einstein’s theories have been the bedrock of modern physics, shaping our understanding of the universe and reality itself. But what if everything we thought we knew was just the surface of a much deeper truth? In February 2025, at Google’s high-security Quantum A-I Campus in Santa Barbara, a team of scientists gathered around their latest creation — a quantum processor named Willow. What happened next would leave even Neil deGrasse Tyson, one of the world’s most renowned astrophysicists, in tears. This is the story of how a cutting-edge quantum chip opened a door that many thought would remain forever closed, challenging our most fundamental beliefs about the nature of reality. This is a story you do not want to miss.
From Star Wars dreams to battlefield reality, laser weapons are finally here—but are they worth the hype? Here’s everything you need to know about the tech, the failures, and the future.
