Dying Bats In The Northeast U.S. Remain A Mystery
Investigations continue into the cause of a mysterious illness that has killed thousands of bats since March 2008. At more than 25 caves and mines in the northeastern US, bats exhibiting a condition now referred to as "white-nosed syndrome" have been dying. The US Geological Survey recently issued a Wildlife Health Bulletin, advising wildlife and officials throughout the US to lookout for the condition known as "white-nose syndrome" and to report suspected cases of the disease.

Stroke Survivors Walk Better After Human-assisted Rehabilitation
Therapist-assisted walking rehabilitation showed greater improvements in walking ability in ambulatory stroke survivors compared to robotic-assisted therapy. Post-stroke patients in both groups improved their walking ability, but the amount of improvement in the physical therapist-assisted group was greater. Robotic devices may be best reserved for acute stroke patients who have no ability to walk on their own.

Fruit Fly Avoidance Mechanism Could Lead To New Ways To Control Pain In Humans
At first, fruit flies eat like horses. Hatching inside over-ripe fruit where they were laid, they feed wildly in the sugar-rich environment until nature sends them an offer they can't refuse. To survive, they must leave the fruit, wander off and burrow into the earth where they avoid food as if it were poison. Only then can the larvae grow and hatch into flies that will take wing to lay their own eggs. Researchers have now discovered that the important developmental switch from food attraction to aversion in the fruit fly larva is controlled by a timing mechanism in the brain and its sensory system. The study shows how this important avoidance mechanism has been recruited into evolutionary processes to promote development and could lead to new methods of controlling pain in humans and other animals.
