The First New Subsea Habitat In 40 Years Is About To Launch

1 month 1 week ago
An anonymous reader quotes a report from MIT Technology Review: Vanguard feels and smells like a new RV. It has long, gray banquettes that convert into bunks, a microwave cleverly hidden under a counter, a functional steel sink with a French press and crockery above. A weird little toilet hides behind a curtain. But some clues hint that you can't just fire up Vanguard's engine and roll off the lot. The least subtle is its door, a massive disc of steel complete with a wheel that spins to lock. Once it is sealed and moved to its permanent home beneath the waves of the Florida Keys National Marine Sanctuary early next year, Vanguard will be the world's first new subsea habitat in nearly four decades. Teams of four scientists will live and work on the seabed for a week at a time, entering and leaving the habitat as scuba divers. Their missions could include reef restoration, species surveys, underwater archaeology, or even astronaut training. One of Vanguard's modules, unappetizingly named the "wet porch," has a permanent opening in the floor (a.k.a. a "moon pool") that doesn't flood because Vanguard's air pressure is matched to the water around it.It is this pressurization that makes the habitat so useful. Scuba divers working at its maximum operational depth of 50 meters would typically need to make a lengthy stop on their way back to the surface to avoid decompression sickness. This painful and potentially fatal condition, better known as the bends, develops if divers surface too quickly. A traditional 50-meter dive gives scuba divers only a handful of minutes on the seafloor, and they can make only a couple of such dives a day. With Vanguard's atmosphere at the same pressure as the water, its aquanauts need to decompress only once, at the end of their stay. They can potentially dive for many hours every day. That could unlock all kinds of new science and exploration.

'Vibe Coding' Named Word of the Year By Collins Dictionary

1 month 1 week ago
Collins Dictionary has named "vibe coding" its 2025 word of the year -- a term coined by Andrej Karpathy for when a user makes an app or website by describing it to AI rather than writing programming code manually. The term, which is confusingly made up of two words, was "one of 10 words on a shortlist to reflect the mood, language and preoccupations of 2025," reports the BBC. From the report: By giving an AI tool a simple description such as "make me a program that schedules my weekly meals", people can use "vibe coding" to make basic apps without any previous programming knowledge. More complicated tools still require skill, but the practice has opened up creating digital platforms to non-coders. As many have discovered, it isn't perfect - with no guarantee the code will actually work or be free of bugs. Alex Beecroft, the Managing Director of Collins, said the term "perfectly captures how language is evolving alongside technology." Other words that made the list include "clanker," "aura farming," "broligarchy," "biohacking," and "coolcation." You can view the full list here.

James D. Watson, Co-Discoverer of the Structure of DNA, Is Dead At 97

1 month 1 week ago
ole_timer shares a report from the New York Times: James D. Watson, who entered the pantheon of science at age 25 when he joined in the discovery of the structure of DNA, one of the most momentous breakthroughs in the history of science, died on Thursday in East Northport, N.Y., on Long Island. He was 97. His death, in a hospice, was confirmed on Friday by his son Duncan, who said Dr. Watson was transferred to the hospice from a hospital this week after being treated there for an infection. Dr. Watson's role in decoding DNA, the genetic blueprint for life, would have been enough to establish him as one of the most important scientists of the 20th century. But he cemented that fame by leading the ambitious Human Genome Project and writing perhaps the most celebrated memoir in science.
