One of the strangest things that can sicken us—a rogue misfolded protein that destroys the brain, known as a prion—is even scarier than we knew. Researchers were able to find the prions responsible for sporadic Creutzfeldt-Jakob disease (sCJD), the most common prion disease in people, seeded everywhere in the eyes of 11 patients affected by it.

A new study published Thursday in Cell Stem Cell is set to further stoke the debate over whether our brain can actually grow back neurons as we age. The research found that people, even into their golden years, are regenerating their stock of neurons right up until the point of death—seemingly contradicting the results of a major study released just last month. Continue reading Maybe Our Brains Actually Can Grow Back Neurons
A 27-year-old man had been suffering frequent headaches and had been falling over frequently for around three years. But when he had a seizure, he headed to the emergency department. They took an MRI and found THIS.
On a mission to Mars, future astronauts will have to leave the protection of Earth’s magnetic field. As they head into deep space, high-energy galactic cosmic rays will pass through the hull of their ship and into their bodies. This might have dangerous—and lasting—consequences for the astronauts’ health.
Conventional wisdom says that brains don’t fossilize, but these seven fossilized brains beg to differ.
There’s this persistent notion that we use a mere 10 percent of our brains at any given moment.If only we could tap into more of the magnificent, squishy machine in our heads, we’d become quicker, cleverer versions of ourselves.
A few months ago I started getting headaches, and they were weird. If a bad hangover headache feels splitting, I’d describe these headaches as searing, as if someone had hit me over the head with a red hot rod of steel sending electric bolts of pain across my skull.
