Burn victim identified by maggots on body“When Mexican police found a body in the woods it was burned beyond recognition, its DNA too damaged to be used for identification. Luckily, investigators were able to extract DNA from elsewhere – the digestive systems of maggots that had been feeding on the body. This is the first time that human DNA from a maggot gut has been analysed in this way to successfully identify a victim in a legal case.”

The Marketplace in Your Brain“Neuroscientists have found brain cells that compute value. Why are economists ignoring them?”

Trans-species polymorphisms“It’s not just that we see the same gene in distantly related species. We also see the same gene with the same set of alleles—a trans-species polymorphism (Klein et al., 1998). A good example is the ABO blood group system. On the basis of that gene marker, I probably have more in common with certain apes than I do with some of my readers.” – (^_^) from peter frost.

bonus: I’m Spantacus! Slave ants rebel“[O]n average 95 per cent of the parasitic ant larvae survived to pupa stage – but then the slave ants attacked or neglected them. Only 45 per cent of the parasite’s offspring survived to adulthood. In comparison, the survival rate for host pupae in their own free-living nests is 85 per cent.”

Europeans did not inherit pale skin from Neanderthals“By analysing the genomes of 50 people with European ancestry and 70 people with sub-Saharan African ancestry, Beleza’s team could estimate when the three genes – and pale skin – first became widespread in European populations. The result suggested that the three genes associated with paler skin swept through the European population only 11,000 to 19,000 years ago.”

Is castration the secret to a long life?“Scientists believe they may have discovered the secret to longevity for men – but it comes at a painfully high price.” – yikes!

Inside the Cold, Calculating Libertarian Mind“[W]hen libertarians reacted to moral dilemmas and in other tests, they displayed less emotion, less empathy and less disgust than either conservatives or liberals. They appeared to use ‘cold’ calculation to reach utilitarian conclusions about whether (for instance) to save lives by sacrificing fewer lives. They reached correct, rather than intuitive, answers to math and logic problems, and they enjoyed ‘effortful and thoughtful cognitive tasks’ more than others do. The researchers found that libertarians had the most ‘masculine’ psychological profile, while liberals had the most feminine….”
