The helpless behavior that is commonly linked to depression and post-traumatic stress disorder (PTSD) is preceded by stress-related losses of synapses—microscopic connections between brain cells—in the brain’s hippocampal region, researchers at Yale School of Medicine report in Biological Psychiatry. 
 
The team used a six-day treatment with the antidepressant desipramine to reverse helpless behavior and restore hippocampal synapses in rats. 
 

Using ESO's Very Large Telescope, astronomers have gained new insights about the atmosphere of Pluto - (it's a dwarf now, get over it.)

What stands out?   Large amounts of methane in the atmosphere and it's hotter than the surface by about 40 degrees, though -180 degrees Celsius is still not the place for your interplanetary tropical vacation. These properties of Pluto's atmosphere may be due to the presence of pure methane patches or of a methane-rich layer covering the dwarf planet's surface.

Astronomers using a telescope aboard the NASA Swift Satellite have captured information from the early stages of a gamma ray burst - the most violent and luminous explosions occurring in the Universe since the Big Bang.

Swift is able to both locate and point at gamma ray bursts (GRBs) far quicker than any other telescope, so by using its Ultraviolet/Optical Telescope (UVOT) the astronomers were able to obtain an ultraviolet spectrum of a GRB just 251 seconds after its onset - the earliest ever captured. Further use of the instrument in this way will allow them to calculate the distance and brightness of GRBs within a few hundred seconds of their initial outburst, and gather new information about the causes of bursts and the galaxies they originate from.

When Alan Pradel of the Muséum National d'Histoire Naturelle in Paris CAT scanned a 300-million-year-old fossilized iniopterygian from Kansas, he and his colleagues saw a symmetrical blob nestled within the braincase.

This turned out to be the oldest brain found in fossil form, a wholly unexpected and rare discovery.

A female moth selects a mate based on the scent of his pheromones. An analysis of the pheromones used by the European Corn Borer (ECB, Ostrinia nubilalis) shows that females can discern a male's ancestry, age and possibly reproductive fitness from the chemical cocktail he exudes.

Jean-Marc Lassance and Christer Löfstedt from Lund University, Sweden, studied the influence of pheromones on mating preferences and carried out an analysis of the composition of the scent and genetic makeup of the animals involved. In addition, they compared the odor bouquet used by males with the scent used by females to attract potential mates.

If you're about to invest in a lot of DVDs for your new baby, here's a way to save some money; they won't help.  Of course, there is some correlation/causation data to classical music but it's correlation/causation data because parents who listen to classical music and buy it for their kids tend to be better educated and care about their kids' education, which is reflected in more ways than just music.
