Hermit Crabs Socialize to Evict Their Neighbors
TEHRAN (FNA)- Social animals usually congregate for protection or mating or to capture bigger prey, but a biologist has found that the terrestrial hermit crab has a more self-serving social agenda: to kick another crab out of its shell and move into a larger home. ( 09:47:23 - 2012/10/29)

Apelike Human Relatives Climbed Trees
TEHRAN (FNA)- Australopithecus afarensis (the species of the well-known "Lucy" skeleton) was an upright walking species, but the question of whether it also spent much of its time in trees has been the subject of much debate, partly because a complete set of A. afarensis shoulder blades has never before been available for study.

Diabetes Raises Levels of Proteins Linked to Alzheimer's Features
TEHRAN (FNA)- Growing evidence suggests that there may be a link between diabetes and Alzheimer's disease, but the physiological mechanisms by which diabetes impacts brain function and cognition are not fully understood. ( 10:19:44 - 2012/10/28)

Drug Used to Treat Glaucoma Actually Grows Human Hair
TEHRAN (FNA)- If you're balding and want your hair to grow back, then here is some good news. A new research report shows how the FDA-approved glaucoma drug, bimatoprost, causes human hair to regrow. ( 10:18:29 - 2012/10/28)

Titanium Oxide Nanotubes Used to Fabricate Optimized Anodes for Fuel Cells
TEHRAN (FNA)- Iranian researchers at Tabriz University succeeded in the production of a porous layer of titanium dioxide nanotubes on the titanium surface, using titanium as the sub-layer and its anodization in organic solutions. ( 10:18:13 - 2012/10/27)

Laser Spotlight Reveals Machine 'Climbing' DNA
TEHRAN (FNA)- New imaging technology has revealed how the molecular machines that remodel genetic material inside cells 'grab onto' DNA like a rock climber looking for a handhold. ( 10:07:30 - 2012/10/27)

Climate Change May Alter Amphibian Evolution
TEHRAN (FNA)- Most of the more than 6,000 species of frogs in the world lay their eggs in water. But many tropical frogs lay their eggs out of water. This behavior protects the eggs from aquatic predators, such as fish and tadpoles, but also increases their risk of drying out. ( 10:06:47 - 2012/10/27)

Scientists Deepen Genetic Understanding of Multiple Sclerosis
TEHRAN (FNA)- Scientists discovered that 30 percent of our likelihood of developing multiple sclerosis (MS) can be explained by 475,806 genetic variants in our genome. ( 14:12:38 - 2012/10/26)
