Drug could prevent memory loss in deep space astronauts

Engadget ------- Cosmic radiation is one of the greatest threats to astronauts embarking on deep space missions, not the least of which is the effect on the brain: it could hinder your memory and destroy vital synapses. Thankfully, you might only need to take some pills. UCSF researchers have discovered that a drug from Plexxikon potentially prevents memory problems from cosmic radiation. Tests on mice show that the medicine forces the brain to replace irradiated immune system cells (microglia) with healthy examples, preventing inflammation that could damage memory functions.
