Study reveals new genes for excessive alcohol drinking
...omosome 9 contains genes that may regulate alcohol consumption
in mice. Our analyses allowed us to narrow our focus from thousands of genes in that region to twenty." "This first microarray-based analysis of a behavioral trait reveals many new research opportunities and exemplifies the rich collaborative potenti...
Mankind benefits from eating less meat
