A sweet tooth may be a 'marker' for the genetic risk for developing alcoholism

... if he or she likes sweets," said Overstreet. "By demonstrating that a liking for sweets is dependent on the family history of alcoholism in young individuals, this paper has provided one further step in developing 'sweet-liking' as a 'marker' for alcoholism. However, there are still problems to overcome, since ...

Study offers new insight into Rett Syndrome

... Whitehead lab has studied this protein for years, demonstrating that when MeCP2 is disabled in mice, the animals manifest Rett-like symptoms. But they couldn't figure out why this happens, and they couldn't find the exact genes that MeCP2 targets. At the same time, Greenberg, who also is a professor of neurobio...
