Several popular sugar substitutes may not be as harmless as they seem. Adults who consumed the most artificial sweeteners showed substantially faster declines in memory and thinking, especially if they were under 60 or had diabetes. The highest intake was linked to cognitive aging roughly 1.6 years faster than the lowest intake. Researchers stressed that more studies are needed before concluding that sweeteners are the cause.

A catastrophic asteroid breakup may have triggered a huge wave of impacts across the inner solar system about 800 million years ago. The debris was launched from near a gravitational gateway controlled by Jupiter, sending fragments toward Earth, the Moon, and Mars. The bombardment may explain ancient lunar craters and could have contributed to major climate and biological changes on Earth.

NASA researchers recently put a new wing design, appearing long and thin with a lightweight structural design, through a series of grueling tests to find its structural limits. What they found left them encouraged about the wing’s potential, even when they pushed it past its intended limits. The 15-foot Structural Wing Experiment Evaluating Truss-bracing (SWEET-15) […]

Description This composite of images taken by NASA’s Psyche mission shows the crescent of Mars grow as the spacecraft approached the planet for a gravity assist from May 2 to May 15, 2026. The series begins with the smallest crescent at the center of the of the image as Mars is farthest from the spacecraft, and progressively […]

In April 2026, NASA’s Office of the Chief Health and Medical Officer (OCHMO) initiated a working group to review updated VTE case information, additional data gathered revealing altered blood flow status within a cohort of astronauts, and discuss progress of research and clinical activities intended to mitigate the risk of VTE during spaceflight with new […]

An experiment showed AI users had the most creative ideas when they used it in moderation – not too much and not too little. Columnist David Robson puts the finding to the test, and explores what we lose when we over-rely on AI

A supplement comprised of dead bacteria seems to remove microplastics, and prevent their absorption into cells, by attracting them to the bacteria's rough surfaces
