West Nile outbreak falls short of 2003 numbers

We're still more than two months from the end of the year, but the number of West Nile Virus (WNV) cases in the United States has already exceeded the second-highest annual total.

As of Tuesday, 4,531 cases of West Nile have been reported to the Centers for Disease Control and Prevention, including 183 deaths. This means the case count has surpassed the totals for 2006, when there were 4,269 cases including 177 fatalities.

But at this point in the year, it's unlikely that another 5,000 cases will develop, so the 2012 WNV season probably won't be the worst on record. That was in 2003, when there were 9,862 illnesses and 264 deaths reported. FULL POST

Your brain on food: Obesity, fasting and addiction

We all know that what you eat can change your physical appearance. It also alters how your body functions, making it more or less difficult to pump blood, grow healthy bones or process insulin.

New research presented this week at the Neuroscience 2012 conference suggests that what you eat can even alter your brain – and vice versa.

Timothy Verstynen and his colleagues used functional magnetic resonance imaging (fMRI) to observe the brain activity in 29 adults. The study participants were shown words on a screen in various colors and asked to identify the color, not the word. Sometimes it was easy – the word red printed in red; other times it was harder, like seeing the word red printed in blue.

The overweight and obese participants’ brains showed more activity during difficult questions, suggesting they were working harder to get the same answers.
