Breast-feeding mums produce different milk for girl and boy babies – girls get more fluids, boys get more fats or proteins.

Another reason why sleep is important – it seems to clear your brain of toxins. During sleep, the flow of fluid around the brain increases, washing away any buildup of waste proteins. This could explain the link between sleep disorders and brain disease such as Alzheimer’s disease.

The research was published in Science.

Researchers have found the gene for a protein that keeps the head on beer stable – so you can thank the fermentation gene CFG1 (Carlsbergensis foaming gene) and the cell wall protein Cfg1p for the foam on your pint.

See the original paper in the Journal of Agricultural and Food Chemistry.

Researchers have created a drug that specifically targets a protein in the testes and stops sperm production in mice, and is reversible – so has potential as a male contraceptive pill. However… one of the effects is shrinking testes, and though it’s reversible, how would people cope with that? And the age old question too – would women trust their partners to take the pill? These aren’t questions that need answering quite yet as it has only been tested in animals so far. As Professor Moira O’Bryan, the head of male infertility at Monash University in Australia, said to BBC News: “Although there is undoubtedly an urgent need for additional contraceptive options, the path between this paper and a new product is likely to be long.”

Read the original research in the journal Cell, and there’s more information here and here.

In a set of articles in the British Medical Journal, researchers debunked a number of claims for sports products. The color of urine—something athletes are told to keep an eye on—depends on many factors, not just hydration. Drinking before you feel thirsty may worsen performance. Energy drinks with caffeine and other compounds have no benefit above and beyond the boost from caffeine. And carbohydrate and protein combinations post-workout don’t improve performance and recovery.

Around 5-10% of the population in the Solomon Islands is blond, and it was thought to be from European ancestors, but researchers have found that it is a separate gene, on chromosome 19.

The research was published in Science.
