Winter immune boost may actually cause deaths, study suggests
Increase in immune defences fights infections, but also raises risk of inflammation, causing heart attacks, stroke and diabetes during winter monthsThe increase in deaths during winter months is typically put down to icy weather, bouts of flu and the more sluggish lifestyles we adopt as the days draw in. Now scientists have suggested that our own immune systems may be to blame for the annual peak in conditions from heart attacks to diabetes and schizophrenia.A study has revealed that the immune system has a seasonal cycle, in which its activity is boosted during the winter and relaxes during the summer. Continue reading...

Inside the mummies' embalmed bodies courtesy of a hospital CT scanner
The British Museum's next big exhibition reveals secrets that experts have been able only to guess at until nowSpare a thought for the unknown adult mummified in a Theban necropolis more than 2,500 years go. Not only did he suffer the most excruciating, possibly life-threatening dental abscesses, but the embalmer botched the afterlife preparation, leaving bits of brain in his skull as well as a broken section of the spatula he was using to remove it.Then there's Tamut, a temple singer with enough calcified plaque in her arteries to risk a heart attack or stroke.

Do No Harm: Stories of Life, Death and Brain Surgery review
Patients see neurosurgeons as gods, but what is the reality? Henry Marsh has written a memoir of startling candourWe go to doctors for help and healing; we don't expect them to make us worse. Most people know the aphorism taught to medical students, attributed to the ancient Greek Hippocrates but timeless in its quiet sanity: "First, do no harm." But many medical treatments do cause harm: learning how to navigate the risks of drug therapies, as well as the catastrophic consequences of botched or inadvised surgical operations, is a big part of why training doctors takes so long. Even the simplest of therapies carries the ri...
