Editor’s note: This interview was conducted in October 2023. As the International Space Station approaches 25 years of continuous human presence on Nov. 2, 2025, it is a meaningful moment to recognize those who have been there since the beginning—sharing the story of human spaceflight with the world. If you have ever witnessed the live Continue Reading
In addition to drilling rock core samples, the science team has been grinding its way into rocks to make sense of the scientific evidence hiding just below the surface. On June 3, NASA’s Perseverance Mars rover ground down a portion of a rock surface, blew away the resulting debris, and then went to work studying Continue Reading
A nerve cell (stained green) growing among a cancer cell culture Simon Grelet and Gustavo Ayala Cancer cells steal energy-generating parts from nerve cells to fuel their spread to distant sites, a discovery that could improve treatments against the deadliest tumours. “This is the first time that mitochondrial exchange has been demonstrated from nerves to Continue Reading
Inhabiting Mars has long been a futuristic fantasy fueled by science fiction. However, successful landings on our neighboring planet over the past half-century have made this seemingly far-fetched idea increasingly plausible. But don’t start packing just yet. First, we must figure out how to build structures millions of miles from Earth. Sending rockets carrying m***ive Continue Reading
Researchers have discovered two new viruses in bats that are closely related to the deadly Nipah and Hendra viruses — pathogens that can cause severe brain inflammation and respiratory disease in humans. The viruses, as well as other new viruses, bacteria, and parasites identified from bat kidneys, were reported this week in the open-access journal Continue Reading
For over a century, scientists have puzzled over a fundamental mystery in our evolutionary history: how did mammals go from sprawling like lizards to striding like cats and dogs? This transition — from a sprawled stance (like a lizard) to an upright (parasagittal) posture — marked a pivotal moment in mammal evolution. While the earliest Continue Reading
“We haven’t designed or validated AlphaGenome for personal genome prediction, a known challenge for AI models,” Google said in a statement. Underlying the AI system is the so-called transformer architecture invented at Google that also powers large language models like GPT-4. This one was trained on troves of experimental data produced by public scientific projects. Continue Reading
In a new paper with implications for preventing Alzheimer’s disease and other neurological disorders, Keith Hengen, an ***ociate professor of biology in Arts & Sciences at Washington University in St. Louis, suggests a new comprehensive approach to understanding how the brain works and the rules it must follow to reach optimal performance. “There’s a common Continue Reading
The skin acts as the body’s first line of defense against external threats. However, as we age, the epidermis — the outermost layer of skin — gradually becomes thinner and loses its protective strength. About 90% of the cells in this layer are keratinocytes, which originate from deeper layers of the epidermis and migrate upward, Continue Reading
Introducing: the Power issue Energy is power. Those who can produce it, especially lots of it, get to exert authority in all sorts of ways. The world is increasingly powered by both tangible electricity and intangible intelligence. Plus billionaires. The latest issue of MIT Technology Review explores those intersections, in all their forms. Here’s just Continue Reading
