Tracking the tell-tale signs of pure genius

A 70-year-old engineer who has just retired confesses that he has had a life-long urge to have his left arm amputated below the elbow. He has the arm removed and feels much better.

Another man loses his arm in a car accident, but still feel its ghostly presence; this phantom limb is clenched in a painfully awkward position.

A third man, a student of mine, makes a remarkable recovery from a coma, only to become convinced that his mother and father are impostors.

All three case studies are fascinating. Yet as I argue in my new book, The Tell-Tale Brain, they can also teach us a great deal about how the brain does its near-miraculous work.

Harvard scientists dramatically reverse aging in mice

At Harvard, they bred genetically manipulated mice that lacked an enzyme called telomerase that stops telomeres getting shorter. Without the enzyme, the mice aged prematurely and suffered ailments, including a poor sense of smell, smaller brain size, infertility and damaged intestines and spleens. But when DePinho gave the mice injections to reactivate the enzyme, it repaired the damaged tissues and reversed the signs of ageing.

The compounds have been linked to cancer, developmental problems, liver damage and other ailments in animals, though there is no general agreement about their effects on humans.”

Left-sided cancer: should you blame your bed and tv?

Curiously, the cancer rate is 10 percent higher in the left breast than in the right…

…researchers suggest an explanation based on differences in sleeping habits in Japan and Western countries…

…as we sleep on our coil-spring mattresses, we are in effect sleeping on an antenna that amplifies the intensity of the broadcast FM/TV radiation. Asleep on these antennas, our bodies are exposed to the amplified electromagnetic radiation for a third of our life spans.
