Study Finds Molecular Link Between Obesity, Hypertension
...ts associated with it, that would be huge."
MC4R, Marks explained, is one of five melanocortin receptors in the brain; these proteins regulate skin coloration
and stress, among other things. But MC4R regulates body weight, "and it does that by altering both appetite and energetics of your body -- your basal ...
Genetic Mutation in Mice Suggests Extinct Mammoth Had Light and Dark Fur
...Coast subspecies, even though these Atlantic coast beach mice have similarly light colored coats. The results suggest that beach mice gain their light coloration
through different genetic mechanisms.
“There is apparently more than one way genetically to become a light-colored beach mouse,” says Hoekstra. ...
Studies On Hearing Loss Discovers New Causes
...The women developed essential tremor in their 20s, and the man in his 50s. All of the individuals had blue eyes without heterochromia (a difference in coloration
in two structures which are normally alike in color.)
Molecular genetic studies failed to link these patients with mutations known to be associat...
Interaction of just 2 genes governs coloration patterns in mice
CAMBRIDGE, Mass. -- Biologists at Harvard University and the University of California, San Diego, have found that a simple interaction between just two genes determines the patterns of fur coloration
that camouflage mice against their background, protecting them from many predators. The work, publ...
ASU research shows connection between testosterone, dietary antioxidants and bird coloration
Mom may have been right all along, especially when we were hormone-raging teenagers, eat your veggies and good things will happen.
In a new physiological study of birds, a researcher at Arizona State University has found that carotenoids, the pigments that color carrots orange and corn yellow, ...

The reason for this mixture of behaviour and coloration
results from a developed defence strategy needed when the snake is probing for prey. Despite being extremely venomous sea snakes are susceptible to at...

Biologists solve mystery of black wolves
