CRISPR offers new hope for treating diabetes

news.ycombinator.com Javier Carbajal 2025-10-06 03:45:28

Crispr gene-editing technology has demonstrated its revolutionary potential in recent years: It has been used to treat rare diseases, to adapt crops to withstand the extremes of climate change, or even to change the color of a spider’s web. But the greatest hope is that this technology will help find a cure for a global disease, such as diabetes. A new study points in that direction.

A Terrace, B.C., beekeeper found herself in a nightmare situation late last month when "thousands and thousands of bees" filled her shop. Call it an attempted robbery — the bees were trying to steal sweet, sweet honey. Christine McDonald, owner of Rushing River Apiaries, said it's the first time desperate "robber bees" — bees that try to take honey from another colony's hive — have descended upon her indoor shop to hunt for food as resources get scarce in the late summer.

Critics are slamming Sen. Ted Cruz's (R-Texas) new AI policy framework, which they claim would give the White House unprecedented authority to allow Big Tech companies to make "sweetheart" deals with the Trump administration to void laws designed to protect the public from reckless AI experiments. Under the framework, Cruz calls for a "light-touch" regulatory approach to "advance American leadership" in AI and ensure that "American values" are at the heart of the world's leading technology—not

New black hole merger bolsters Hawking area theorem

arstechnica.com Unknown 2025-10-06 08:41:19

Back in 1971, the late physicist Stephen Hawking made an intriguing prediction: The total surface area of a black hole cannot decrease, only increase or remain stable. So if two black holes combine, the newly formed black hole will have a larger surface area. This became known as Hawking's area theorem. Analysis of the gravitational signal from a black hole merger detected in January provides the best observational evidence to date in support of Hawking's theorem, according to a new paper publis
