A study reveals that the severity of learning disorders may depend not only on the child's environment but also on the mother's environment when she was young.

The researchers studied the brain function of pre-adolescent mice with a genetically-created defect in memory. When these young mice were enriched by exposure to a stimulating environment – including novel objects, opportunities for social interaction and voluntary exercise – for two weeks, the memory defect was reversed. The work showed that this enhancement was remarkably long-lasting because it was passed on to the offspring even though the offspring had the same genetic mutation and were never exposed to an enriched environment. 

A new testosterone patch, designed to pep up a woman's flagging sex drive after womb and ovary removal, may not work, and its long term safety is not proven, says the Drug and Therapeutics Bulletin (DTB).

Intrinsa was recently licensed in the UK for the treatment of women, who have gone through the menopause as a result of womb and ovary removal, and who are subsequently experiencing a drop in sex drive.  The condition is referred to as hypoactive sexual desire disorder or HSDD for short.

There is some evidence to suggest that a fall in sex drive after the menopause might be linked to low levels of circulating testosterone.

A likable rogue-ish historian ( Hank Campbell, only in tweed, we might describe him, Harrison Ford being a little long in the tooth for action films these days) is poring over antique tomes, including an original draft copy of  On the Origin of Species by Means of Natural Selection, or The Preservation of Favoured Races in the Struggle for Life when he notices a very faint trace of eraser markings on the title page.    He does some kind of magic chemical stuff (whatever - it's a movie) and discovers it is a number.

The birth of new species always involves a barrier to cross-breeding between two different groups of the same species. This barrier may start out as a geographical barrier (two raccoon populations on different sides of a mountain never encounter each other and thus fail to interbreed), but however it starts, reporductive barriers always turn into a genetic barrier. To form new species, two populations of organisms have to drift apart genetically.

The genetic split can happen in a variety of ways, as scientists are discovering in the their quest to find 'speciation genes.' It can happen because a selfish gene fails to be shut down in the offspring of cross-breeding flies, and it can happen because one mouse gene doesn't work right when it encounters genetic variants from another subspecies.

A report in Science describes one more speciation gene, this time in two sub-species of thale cress plants. In this case, the barrier to reproduction is the result of faulty gene copying.

When most of us, especially in the SB community, think of supercomputers we usually think of large-scale hydrodynamics or fusion reaction simulations which stretch our knowledge of the universe and provide us with a validation or a denial or of some complicated physical theory.

Indeed, this is what most supercomputers are up to: simulating climate change, the structure of proteins, or the dynamics of a supernova, while producing awesome pictures like this one:

If you have not already chosen your new love, researchers suggest you stay away from those with big chins as they have a tendency to cheat. Researchers from four universities across the US and Canada prodded into the sexual habits of chinny and relatively chin-less females to determine these results.
