Creating ‘genomic origami’
Researchers have assembled the first high-resolution, 3-D maps of entire folded genomes and found a structural basis for gene regulation, a kind of “genomic origami” that allows the same genome to produce different types of cells.

Diabetes’ genetic variety
Harvard researchers working at the Broad Institute of MIT and Harvard have uncovered nine rare genetic mutations that dramatically increase the risk of developing type 2 diabetes. The discovery of the mutations highlights the dizzying genetic diversity of a disease rapidly spreading around the world.

Viewing how neurons work
A new technique for observing neural activity will allow scientists to stimulate neurons and observe their firing pattern in real time. Tracing those neural pathways can help researchers answer questions about how neural signals propagate, and could one day allow doctors to design individualized treatments for a host of disorders.

Clues to cholera resistance
Researchers have long understood that genetics can play a role in susceptibility to cholera, but a team of Harvard scientists is now uncovering evidence of genetic changes that might also help protect some people from contracting the deadly disease.

When timing is everything
In a new paper, Christopher Marx, associate professor of organismic and evolutionary biology, says that beneficial mutations may occur more often than first thought, but many never emerge as “winners” because they don’t fall within the narrow set of circumstances required for them to dominate a population.

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…

Solving a biological mystery
A team of Harvard researchers has shown that insects like crickets possess a variation of a gene — called oskar — that is critical to the production of germ cells in “higher” insects. That discovery suggests that the oskar gene emerged far earlier in insect evolution than researchers previously believed.

CYCLOPS genes an Achilles’ heel in tumors?
Researchers at Harvard-affiliated Dana-Farber Cancer Institute and the Broad Institute of Harvard and MIT used new technology to explore a 19-year-old theory, discovering what may be an Achilles’ heel for cancer cells: essential genes disrupted in the process of becoming cancerous that can be attacked further with drug therapy.

Mapping mollusks
Using genetic tools, researchers at Harvard and collaborating institutions have completed the most comprehensive evolutionary tree ever produced for mollusks. Described in the Nov. 2 issue of Nature, the work also serves as a proof-of-concept, demonstrating the power of genomic techniques to answer difficult evolutionary questions.

Finding ovarian cancer’s vulnerabilities
In their largest and most comprehensive effort to date, researchers from the Broad Institute of Harvard and MIT and Dana-Farber Cancer Institute, a Harvard affiliate, examined cells from more than 100 tumors, including 25 ovarian cancer tumors, to unearth the genes upon which cancers depend. They call it Project Achilles.
