The finding effectively paves the way for continued use of atrazine, a widely used herbicide that has been linked to birth defects and cancer in humans.

Captured by the multispectral imager instrument on NASA’s Psyche mission, this is an enhanced-color view of the large double-ring crater Huygens (upper right; about 290 miles, or 470 kilometers, in diameter) and the surrounding heavily cratered southern highlands near 15 degrees south latitude.

This view of the Martian surface, captured by NASA’s Psyche spacecraft on May 15, 2026, shows streaks that have formed due to wind blowing over impact craters in the Syrtis Major region.

Description This is the highest-resolution view of the water ice-rich south polar cap of Mars captured by NASA’s Psyche mission after it made its close approach with the planet for a gravity assist. The image scale is around 0.7 miles per pixel (1.14 kilometers per pixel). The cap itself extends across more than 430 miles […]

The rules were established by the Biden administration after research linked the compounds to a range of serious health problems.

Description This is Psyche’s first view of a nearly “full Mars” seen shortly after the spacecraft’s closest approach to the planet on May 15, 2026. The view extends from the south polar cap northwards to the Valles Marineris canyon system and beyond. With Mars in the rearview mirror, the spacecraft will soon resume use of […]

Description This view of a crescent Mars was captured on May 15, 2026, at about 5:03 a.m. PDT by NASA’s Psyche mission as it approached the planet for a gravity assist. Captured by the spacecraft’s multispectral imager instrument, this was the last view of the whole planet before it began to overfill the field of […]

Scientists spent decades chasing signs of a mysterious new force hidden inside the muon, one of nature’s strangest particles. But after years of supercomputer calculations, researchers discovered the apparent anomaly was likely a calculation error — and the Standard Model still reigns supreme.

Renewable energy has helped make the worst-case scenario a bit less bad. The president said, falsely, it shows that climate scientists were wrong all along.

Scientists have uncovered remarkable new details about Bronze Age life in Central Europe by studying rare burials untouched by cremation. The research reveals communities experimenting with new foods, burial rituals, and cultural connections while largely staying rooted in their local homelands.
