One tiny gene switch turns red lettuce upside down and reveals a hidden chemical tradeoff

This observation from NASA's Hubble Space Telescope, released on March 23, 2026, gives an unparalleled, detailed look at the aftermath of a supernova and how it has evolved over the telescope's long lifetime.

Tens of kilometers above Earth's surface, high-energy particles from outer space constantly strike the atmosphere, creating showers of energetic secondary particles that rain down from the sky. Approximately one of these particles passes through your head every second, but the "cosmic rays" that produce them are still not fully understood. In a recent paper posted to the arXiv preprint server, the ATLAS Collaboration describes how its first measurement of proton–oxygen collisions at the LHC coul

Scientists from the Laboratory of Dermatological Photobiology of the University of Malaga, in collaboration with Cantabria Labs España, have carried out a study in which, for the first time, they have demonstrated how a natural extract—the Aspalathus linearis, the rooibos plant—could improve the effectiveness of traditional sunscreens, enhancing their absorption capacity, increasing their antioxidant levels, and providing longer-lasting protection against the risks of radiation.

Young children who spend more time on screen-based activities and less time talking with adults tend to have weaker language skills, according to a recent study from the University of Tartu. The findings highlight that daily interaction—rather than screen limits alone—plays a key role in early language development. The study is published in the journal Frontiers in Developmental Psychology.
