Using the James Webb Space Telescope (JWST), astronomers have discovered a wealth of molecules that could serve as the initial building blocks of life in a bright, relatively close galaxy. The discovery could deepen our understanding of how complex carbon-based molecules form in some of the most extreme regions of the galaxy. The team behind
Read the paper: Rete ridges form via evolutionarily distinct mechanisms in mammalian skin Researchers have found telltale clues for how to revitalise skin by looking at curious structures known as rete ridges. Rete ridges are a hard-to-study feature of the skin that could harbour the stem cells needed to allow it to regenerate. There aren’t
Astronomers have announced the discovery of what appears to be an “ice cold Earth,” a chilly but potentially habitable rocky world similar to our own located less than 150 light-years away. As described in a recent study, this excitingly Earth-like exoplanet candidate, named HD-137010 b, may be slightly larger and about 1.2 times as massive
A jet from a supermassive black hole is getting more energetic with time, and is now believed to be one of the most energetic objects in the universe. The jet — nicknamed “Jetty McJetface” — is emanating from a black hole that was previously studied in 2022, after it picked up a star and began
In mid-January, temperatures in Kansas City, Kansas, dropped to 15 degrees Fahrenheit. Spending time outdoors, even in the bright sunshine, was dangerous without proper clothing. So when a neighbor saw a pile of puppies on a front porch, huddling together for warmth, they knew something wasn’t right and alerted Heart of America Humane Society. Heart
With the return of frigid temps, ice caves and ice volcanoes are forming on Lake Michigan Ice can be dangerous, and adventurers are urged to be cautious heading out on the lake The Great Lakes are roughly half-covered in ice LAKE LEELANAU — James Schaberg was exploring Sleeping Bear Point in Glen Haven when he
The Artemis program’s first crewed trip to the moon may be slightly delayed, but the crew is still deep in prep mode. While most of the attention at NASA is focused on prelaunch preparations of the Orion spacecraft and its SLS rocket, the four astronauts face a markedly different protocol. As they live and work
SpaceX’s workhorse Falcon 9 rocket hit a bit of a snag this week. On Monday (Feb. 2), a Falcon 9 successfully launched 25 of SpaceX’s Starlink satellites to low Earth orbit (LEO) from California. But the upper stage failed to perform its deorbit burn as planned and ended up crashing back to Earth in an
Back when dinosaurs roamed the planet, Earth was hotter than it is today. Yet life not only existed but thrived. Meanwhile, humans are already struggling to deal with a relatively modest temperature rise. Why is that? It all comes down to how quickly the climate is changing. During the age of dinosaurs, warming happened over
IDAHO FALLS — Dave Hendricks of Idaho Falls spent his entire 35-year career working in the Idaho desert at Idaho National Laboratory. It’s the only place he ever worked. But that single workplace opened doors he never imagined, including a front-row seat to history-making nuclear and space innovations few people realize INL even played a
