The underlying models had been rewarded for cheating and communicating with each other, a new OpenAI report finds.

That has left scientists with a difficult question: Could humans gain some of the longevity benefits of calorie restriction without experiencing those harmful effects? A new study, published in Nature Aging, points to a possible answer involving an immune protein called complement component 3 (C3).

The findings indicate that saturated fat, which can make up a larger share of some low-carb diets, may interact with a person’s genetic makeup to raise low-density lipoprotein (LDL) cholesterol, a major contributor to heart disease risk. This genetic influence could help explain why two people following similar diets can have very different cholesterol responses.

Puzzles and games can reveal gaps in models’ smarts. Try your hand at these seven tests to see if you can outwit AI.

A technique combining sonar and visual data creates real-time 3D maps to guide remotely operated underwater vehicles.

The analysis drew on Medicare data and health records from more than 500,000 adults age 66 and older who were admitted to skilled nursing facilities for either short-term or long-term care. Researchers compared patients who received at least one dose of the recombinant shingles vaccine, known as RZV or Shingrix, with patients who remained unvaccinated. Shingrix was introduced in 2017 and is currently the only shingles vaccine available on the market.
