Carbon dioxide is 'driving fish crazy' (January 21, 2012) -- Rising human carbon dioxide emissions may be affecting the brains and central nervous system of sea fishes with serious consequences for their survival, an international scientific team has found. Carbon dioxide concentrations predicted to occur in the ocean by the end of this century will interfere with fishes' ability to hear, smell, turn and evade predators, says a professor. ... > full story

Advance toward an imaging agent for diagnosing Alzheimer's disease (January 21, 2012) -- Scientists are reporting development and initial laboratory tests of an imaging agent that shows promise for detecting the tell-tale signs of Alzheimer's disease in the brain -- signs that now can't confirm a diagnosis until after patients have died. ... > full story

Manganese may have potential in neutralizing deadly Shiga toxin (January 21, 2012) -- Researchers have discovered that manganese, an element commonly found in nature, might provide a way to neutralize the potentially lethal effects Shiga toxin. New results could pave the way for future research aimed at creating an inexpensive treatment for infections caused by bacteria that produce the Shiga toxin. Currently there is no treatment for such infections that afflict more than 150 million people each year, resulting in more than one million deaths worldwide. ... > full story
