🔬 Ancient Cosmic Giants That Shouldn't Exist & A Shark Hiding for 125 Million Years — Just Discovered

Astronomers have spotted 31 of the oldest quasars ever detected, including two that formed when the universe was barely 670 million years old — and scientists can't fully explain how they got so massive so fast. In biology, the goblin shark, a living fossil unchanged for 125 million years, has been captured on film in its natural deep-sea habitat for the very first time. Researchers have also uncovered that developing neurons routinely break and repair their own DNA millions of times during brain formation, revealing that healthy brains are built through controlled chaos. On the medical front, an experimental molecule has shown the ability to reactivate the brain's immune cells to clear Alzheimer's-linked plaques, improving memory in animal studies. From a 150-year-old mystery about gallium finally solved, to oak trees quietly absorbing carbon long after they stop growing, this episode is packed with discoveries that are rewriting what we thought we knew.Subscribe to Peer Review'd Newsletter: https://peerreviewd.com/Love Science?
