Roots of brutality

ns_logoWHY would an apparently normal young adult drop out of college and turn up some time later in a video performing a cold-blooded execution in the name of jihad? It’s a conundrum we have been forced to ponder ever since a group calling itself ISIS declared war on infidels. But 70 years ago we were asking something similar of guards in Nazi concentration camps – and, sadly, there have been plenty of opportunities to ponder the matter in between…

The idea that it might be the obverse of something good sounds, to say the least, counter-intuitive. Yet that is the contention of a small band of neuroscientists who have been studying it. They suggest the underlying cause of Huntington’s, a strange form of genetic mutation called a triplet-repeat expansion, might also be one of the driving forces behind the expansion of the human brain. Huntington’s, these people suspect, may be a price humanity pays for being clever…

The forgetting gene

ONE day in 1991, neurologist Warren Strittmatter asked his boss to look at some bewildering data. Strittmatter was studying amyloid-β, the main component of the molecular clumps found in the brains of people with Alzheimer’s disease. He was hunting for amyloid-binding proteins in the fluid that buffers the brain and spinal cord, and had fished out one called apolipoprotein E (ApoE), which had no obvious connection with the disease…
