Psychedelic drugs change brain cells in ways that could help fight depression, addiction and more – Psychedelic drugs like LSD can change brain cells in rats and flies, making neurons more likely to branch out and connect with one another. This supports the theory that psychedelics could help fight depression, anxiety, addiction and post-traumatic stress disorder.

Herpes may play a role in developing Alzheimer's, a new study suggests — reigniting a controversial theory about what causes the disease – One controversial theory for Alzheimer's disease is that it is caused by a virus, or multiple viruses, infecting the brain. A new study rekindles that theory, after finding brains of Alzheimer's patients had higher levels of the herpes virus.

New electronic skin allows bionic limbs to feel pain — and that’s a good thing – Bionic prostheses have evolved by leaps and bounds. One thing that most of them can't do, however, is let their wearers feel pain. That's changing thanks to researchers at Johns Hopkins University -- and, despite what you might think, that could turn out to be a positive step forward.
