Putting mice into hibernation causes a major loss of synapses

Scientists have discovered that inducing a hibernation-like state in mice dramatically reduces the number of neural connections in their brains. Surprisingly, despite this significant synaptic pruning, the animals appear to retain previously formed memories, raising fascinating questions about how memory is actually stored and maintained in the brain.

NASA calls off mission to rescue Swift gamma-ray observatory

NASA has abandoned plans to send a rescue mission to its Swift gamma-ray observatory, a space telescope that has been studying high-energy cosmic events since 2004. Without intervention, the aging spacecraft is expected to fall back into Earth's atmosphere sometime later in 2025, effectively ending a two-decade scientific legacy.
