    These overlooked brain cells may control fear and PTSD

    Astrocytes, once thought to be mere brain “support cells,” are now revealed to be key players in fear memory. Researchers found they actively help form, recall, and weaken fear responses by interacting with neurons in real time. Changing astrocyte activity directly altered how strong fear memories became. This breakthrough could lead to entirely new treatments for anxiety-related disorders.

    Dying stars are devouring giant planets, astronomers discover

    Dying stars may be wiping out nearby giant planets as they expand into red giants. Astronomers found that these close-in planets become increasingly rare around more evolved stars, suggesting many have already been swallowed. The likely cause is a gravitational tug that drags planets inward until they break apart or fall into the star. It’s a dramatic glimpse into the chaotic final stages of planetary systems.

    Students found a star from the dawn of the universe drifting into the Milky Way

    A group of undergraduate students stumbled into a cosmic time capsule—one of the oldest stars ever discovered—while combing through massive astronomy datasets. What began as a class project quickly turned into a breakthrough when they spotted an extraordinarily “pristine” star made almost entirely of hydrogen and helium, hinting it formed near the dawn of the universe.
