For the first time ever in humans, neuroscientists have penetrated the stubborn barrier that protects the brain from toxins in the bloodstream. The breakthrough means that doctors can now deliver drugs to previously inaccessible parts of the brain, making it easier to treat cancer and neurodegenerative disorders.
The eighth season of Doctor Who, starring Peter Capaldi as the brand-new Twelfth Doctor, arrives this August, and the BBC has released the very first teaser trailer! And when I say "teaser trailer," I mean "hilariously brief footage that is essentially a still photo of Capaldi in silhouette." It's ridiculous.
