ScienceDaily (Apr. 28, 2011) The size and shape of the human cerebral cortex, an evolutionary marvel responsible for everything from Shakespeare's poetry to the atomic bomb, are largely influenced by mutations in a single gene, according to a team of researchers led by the Yale School of Medicine and three other universities.

ScienceDaily (Jan. 27, 2011) In a new study, scientists at the University of Maryland and the Institut Pasteur show that bacteria evolve new abilities, such as antibiotic resistance, predominantly by acquiring genes from other bacteria.

The researchers new insights into the evolution of bacteria partly contradict the widely accepted theory that new biological functions in bacteria and other microbes arise primarily through the process of gene duplication within the same organism. Their just released study will be published in the open-access journal PLoS Genetics on January 27.

ScienceDaily (Nov. 14, 2009) A gene in the brain that was not previously linked to mood disorders could have a role in biopolar, depression, and schizophrenic conditions.

Pharmacy scientists at the University of Maryland, Baltimore (UMB) have identified antidepressant and anti-anxiety behaviors in tests of mice lacking the gene.
