This Is Your Brain on Creatine

What’s the first thing that comes to mind when you think of creatine? The supplement has long been lumped in with meathead mythology — blame the branding — but the science tells a different story. As it turns out, creatine is one of the most rigorously studied and broadly beneficial on the shelf.

“People mostly know creatine for muscle building,” says Dr. Bill Kapp, CEO of AI-powered longevity center Fountain Life, “but what many don’t know is that it also helps the brain by boosting brain energy, memory and clear thinking.”

Victor Vescovo Is a Deep-Sea Pioneer in a Post-Titan World

It’s a few years away, but Victor Vescovo has already started working on the design of his next submersible. It will likely go faster, have better maneuverability, greatly improved sonar and — thanks to work with an unnamed U.S. university — possibly have a “robot” manipulation arm that’s based around an electrically-actuated artificial muscle, the prototype of which should be unveiled in around 18 months. Then Vescovo will be ready to get back into the water. Maybe.

Every Part of “The Pitt” Was Brilliant, Right Down to Dr. Robby’s Watch

The Pitt is, in a word, raw. If you haven’t been following along with the gritty emergency room drama, which concluded its first season yesterday, here’s the gist — the show follows a cast of underfunded, understaffed, and under-therapized emergency doctors as they deal with a day (each of the 15 episodes encapsulates an hour of the shift) of deaths, workplace drama and the trauma of providing healthcare in 2025.

If this sounds brutal, bordering on unwatchable, that’s because it is. But The Pitt is also a masterful presentation of humanity, grounded by characters like Dr. Michael “Robby” Robinavitch, played by the enigmatic and impossibly soulful ER veteran Noah Wyle, and, unassuming as it may be — there’s a notable lack of versatility when it comes to hospital garb — by the costume design, as well.
