Scientists may have finally found how Alzheimer's spreads through the brain
Researchers have identified a potential mechanism by which Alzheimer's disease propagates through the brain, with a common protein appearing to shuttle toxic Tau from damaged neurons into healthy ones. The discovery points toward a possible intervention point — blocking these harmful protein packages before they can infect new cells. If validated, the finding could open a new front in the decades-long effort to slow Alzheimer's progression.

The largest digital camera ever built begins decade-long survey of the universe
The Vera C. Rubin Observatory's 3.2-gigapixel LSST Camera has officially begun its decade-long survey of the southern sky, capturing cosmic phenomena at an unprecedented scale. The instrument will image the entire visible sky every few nights, generating a timelapse of the universe that astronomers expect to reveal billions of previously uncatalogued objects. The data collected over the next ten years could reshape our understanding of dark matter, dark energy, and the structure of the cosmos.

The rise of space AI might explain the Fermi paradox
The Fermi paradox asks why, given the vastness of the universe, we've detected no signs of other civilizations — and a new paper suggests AI may be the answer. Austrian researcher Sergey Ivliev argues that the widespread adoption of artificial intelligence could fundamentally reshape humanity's trajectory into space, with implications for how intelligent life develops across the galaxy. If AI-driven civilizations follow a predictable pattern, it may help explain why advanced species go silent — or disappear altogether.

NASA launches robot to rescue aging Swift telescope from fiery demise
NASA is sending a robotic spacecraft to dock with its 20-year-old Swift Observatory, which is running low on the fuel needed to keep it from reentering Earth's atmosphere. The mission represents a rare attempt to extend the life of an aging science asset rather than let it burn up on reentry. If successful, it could set a precedent for salvaging other spacecraft facing premature retirement.
