Human stem cells become more active in space — and that’s not a good thing

Human stem cells become more active in space — and that’s not a good thing

Human stem cells get worn out and age much faster in space, a new study has found, which is a problem for anyone hoping to take a long trip through our solar system. Scientists used artificial intelligence (AI) to track changes to stem cells delivered by SpaceX resupply missions to the International Space Station (ISS). Up in space, the stem …

Human stem cells age more rapidly in space, study finds

While scientists are still working to understand the effects an extended trip to space can have on the human body, research in recent years has suggested that astronauts may experience some pretty dramatic changes on both the physiological and psychological levels. In the latest study led by a team at University of California San Diego, researchers found signs of accelerated …

Spotlight: AI Boom, Human Doom?

Spotlight: AI Boom, Human Doom?

Geoffrey Hinton, widely regarded as the “godfather of artificial intelligence,” has sounded another stark warning about the future of work. He believes AI will make corporations more profitable than ever, but at the devastating cost of widespread unemployment. “Rich people are going to use AI to replace workers,” Hinton said in an interview with the Financial Times. “It’s going to …

The universe’s first magnetic fields were ‘comparable’ to the human brain — and still linger within the ‘cosmic web’

The universe’s first magnetic fields were ‘comparable’ to the human brain — and still linger within the ‘cosmic web’

The universe’s first magnetic fields may have been much weaker than we first imagined — and were roughly equivalent to the strength of the magnetic activity within the human brain, according to a new study. Researchers used hundreds of thousands of computer simulations to examine the remnants of these ancient magnetic fields, which still reside within the “cosmic web” billions …

Gene that human ancestors lost millions of years ago could help treat gout

Gene that human ancestors lost millions of years ago could help treat gout

Millions of years ago, humans’ ancestors lost the function of a specific gene — but switching that gene back on could help protect people from gout, a new experimental study suggests. Gout is a type of arthritis that causes sudden, severe pain and swelling in the joints. It happens when there is too much uric acid in the blood, which …

We led NASA’s human exploration program. Here’s what Artemis needs next.

The recent passing of retired Navy Capt. Jim Lovell, an astronaut and one of our great American heroes, propelled many of us back to the iconic scenes from the superb retelling of the Apollo 13 movie in 1995. The three of us lived through that fateful mission in 1970, as the astronauts and mission control team dealt with critical issue after …
