Longevity diets often focus on going plant-based, but a study in China has linked eating meat to a long lifespan, particularly among older people who are underweight

Professional mathematicians have been stunned by the progress amateurs have made in solving long-standing problems with the assistance of AI tools, and say it could lead to a new way of doing mathematics

If your New Year’s resolution is to understand quantum computing this year, take a cue from a 9-year-old podcaster talking to some of the biggest minds in the field, says quantum columnist Karmela Padavic-Callaghan

NASA’s crawler-transporter 2 moves toward the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Friday, Jan. 9, 2026. The crawler will transport NASA’s SLS (Space Launch System) rocket with the Orion spacecraft to Launch Complex 39B ahead of the Artemis II launch.

Additive Manufacturing, more commonly known as 3D printing, will be an absolutely critical technology for any long-term settlement on another world. Its ability to take a generic input, such as plastic strips or metal powder, and turn it into any shape of tool an astronaut will need is an absolute game changer. But the chemistry behind these technologies is complicated, and their applications are extremely varied, ranging from creating bricks for settlements to plastics for everything from cups to toothbrush holders. A new paper available in pre-print on arXiv from Zane Mebruer and Wan Shou of the University of Arkansas, explores one specific aspect of a particularly important type of 3D printing, and realized that they could save millions of dollars on Mars missions by simply using the planet’s atmosphere to help print metal parts.

As NASA moves closer to launch of the Artemis II test flight, the agency soon will roll its SLS (Space Launch System) rocket and Orion spacecraft to the launch pad for the first time at the agency’s Kennedy Space Center in Florida to begin final integration, testing, and launch rehearsals. NASA is targeting no earlier.
