Molecular motor shuttles key protein in response to light
...aster than if it just moved passively, essentially wandering to the other side of the cell." The researchers will now study mice to see if there are similar chemical controls of light adaptation. They will also start examining other proteins that move in response to light in both flies and mice. The research w...Advanced sensors, computing systems tracking sea animals worldwide
...ists can put tags on bluefin tuna, blue whales and wandering albatrosses and follow what they do for the entire year," said marine mammal expert Andrew Read, an assistant professor of marine conservation biology at Duke's Nicholas School of the Environment and Earth Sciences.

... relatives of the cobra," he says. Fry's worldwide wandering has also boosted the number of what were previously assumed to be non-venomous snakes from a mere few hundred to more than 2000. These snakes typically have smaller quantities of venom and lack fangs, but they can still deliver their venom via their ...Reduced daily eye patching effectively treats 'lazy eye'
...The most common causes of amblyopia are crossed or wandering eyes or significant differences in refractive error, such as farsightedness or nearsightedness, between the two eyes. Without treatment compliance in early childhood, visual impairment can persist into adulthood. Patching the unaffected eye has been ...Too many turtles may end up as roadkill

To help protect pond turtles from collisions in developed areas, the researchers recommend establishing buffer zones around aquatic habitats. Protecting land turtles from collisions will take more.

Other studies demonstrated how these signals are translated into action by the axon. Cancer In The Crosshairs: 2001 ...Fragmentation linked to stress in birds

Birds in fragmented habitats elsewhere may be even more stressed because the fragmentation in this study was relatively mild.
