- #4 Score 28Scientists make quantum time flow backward in stunning physics breakthrough
Researchers have created quantum control techniques that can make a system appear to run backward in time. By precisely managing quantum measurements, they can reshape the system's arrow of time and even harvest energy from the measurement process itself. The breakthrough could lead to more powerful quantum computers, quantum batteries, and other advanced technologies.

Robert F. Kennedy Jr. and his allies promised public-health libertarianism. The idea couldn’t survive once they took power.
- #6 Score 27Old muscle stem cells can act young again but there’s a catch
Scientists at UCLA discovered a surprising reason aging muscles heal more slowly. In older muscle stem cells, a protein called NDRG1 builds up and acts like a brake, slowing the cells’ ability to jump into repair mode after injury. But there’s a twist: that same protein helps the cells survive the stresses of aging, allowing them to stick around longer.
- #7 Score 12A strange LIGO signal could reveal the missing link behind dark matter
An unusual gravitational wave signal has renewed hopes that primordial black holes, long considered purely theoretical, may finally be within reach of discovery. If confirmed, they could solve one of astronomy's greatest mysteries by explaining the nature of dark matter.
- #8 Score 9Scientists stunned as bumble bees solve a classic intelligence test
Bumble bees astonished researchers by inventing a new way to reach a hidden reward, despite never being taught the trick. The discovery adds to growing evidence that these tiny insects are far smarter and more adaptable than once believed.
