Human endogenous retroviruses that colonized vertebrate DNA millions of years ago have long been dismissed as junk DNA, but researchers now know that they may play important roles in cancer, neurodegeneration, and other ailments.
Clinical trials that target human endogenous retroviruses to treat multiple sclerosis, ALS, and other ailments are underway, but many questions remain about how these sequences may disrupt our biology.
Neuropsychologist Simon Thompson found a possible link between yawning and multiple sclerosis. So what better way to get under the skin of his research than volunteering to take part in one of his experiments?
