Why I consumed my own blood

Michael Mosley has been putting his own blood through a series of rigorous tests. In 1897 Bram Stoker's Dracula was published, helping fan an interest in blood-drinking human vampires that has never gone away. In the novel, Count Dracula feeds on human blood and transforms himself from a little old man with white hair into a dark-haired super-athlete. Stoker's novel, and others that came before it (such as "Carmilla", a novel about a lesbian vampire) were in turn inspired by centuries of mythology that have surrounded blood, mainly focused on its alleged powers to heal and restore.

In later centuries, medical practice focused more often on blood letting than blood consumption, but the belief in the power of blood to restore and rejuvenate persisted.

Air-conditioning: Why might women feel temperature differently to men?

Is there an explanation for why men and women might feel comfortable at different room temperatures, asks Chris Stokel-Walker. A study by two Dutch scientists has offered an answer to the longstanding question many office workers ask come summer - why when some men in the office are reaching for the air conditioning, are some women slipping on cardigans? According to the paper, women feel the cold more readily - one small sample test the researchers carried out suggests that women are comfortable at a temperature 2.5C warmer than men - between 24-25C. According to Prof Paul Thornalley, of Warwick Medical School, variation in average metabolic rate and body heat production between men and women "may explain why there is a difference in environmental temperature required for comfort between males and females".
