Rapid evolution, illustrated
A study in which mice were released into outdoor enclosures to track how light- and dark-colored specimens survived confirms that mice survive better in similarly colored habitats, providing insights into evolution.

When cooperation counts
A new study conducted by Harvard scientists shows that in deer mice, a species known to be highly promiscuous, sperm clump together to swim in a more linear fashion, increasing their chances of fertilization.

One gene, many mutations
In a new paper, Harvard researchers show that changes in coat color in mice are the result not of a single mutation, but of many mutations, all in a single gene. The results start to answer one of the fundamental questions about evolution: Does it proceed by huge leaps — single mutations that result in…

Digging yields clues
As described in a Jan. 16 paper in Nature, a team of researchers led by Hopi Hoekstra, professor of organismic and evolutionary biology and molecular and cellular biology, studied two species of mice – oldfield mice and deer mice – and identified four regions in their genome that appear to influence the way they dig…

Animal scents
A Harvard study of how mice respond to scent cues from potential mates, competitors, and nearby predators has laid a foundation for further investigations that may eventually lead to a greater understanding of social recognition in the animal brain, with implications for a host of human disorders ranging from autism to post-traumatic stress disorder.

Partial reversal of aging achieved in mice
Harvard scientists at Dana-Farber Cancer Institute say they have for the first time partially reversed age-related degeneration in mice, resulting in new growth of the brain and testes, improved fertility, and the return of a lost cognitive function.

Sperm competition, cooperation
Some mouse sperm can discriminate between their brethren and the competing sperm from other males, showing an unusual behavioral complexity.

Cancer vaccine success
A cancer vaccine carried into the body on a carefully engineered, fingernail-sized implant is the first to successfully eliminate tumors in mammals, scientists report this week (Nov. 25) in the journal Science Translational Medicine.
