A new view of DNA
A new imaging technique, developed by Erez Lieberman-Aiden, a Junior Fellow of the Society of Fellows, is giving scientists their first three-dimensional view of the human genome, one that is already shedding new light on a number of what Liberman-Aiden calls the “central mysteries of biology.”

In the genes, but which ones?
A team of researchers, led Harvard Professor David I. Laibson and Christopher F. Chabris of Union College, has found that virtually all claims that intelligence is associated with specific genes are wrong.

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.

Designing gene
Taking advantage of the simple color pattern of deer mice, Harvard researchers showed that small changes in the activity of a single pigmentation gene in embryos generate big differences in adult color pattern.

Two studies prove value of iPS cells
A team of Harvard Stem Cell Institute (HSCI) researchers, in collaboration with scientists at Columbia University, have demonstrated that many iPS cells (stem cells created by reprogramming adult cells) are the equal of human embryonic stem cells in creating human motor neurons, the cells destroyed in a number of neurological diseases, including Parkinson’s.

A new target for Parkinson’s therapy
In a new finding from Harvard-affiliated Brigham and Women’s Hospital (BWH), researchers identify a link between Parkinson’s disease onset and dysfunctional activity of energy genes in the brain and identify a potential therapeutic target to reverse this energy gene failure.

Throwing a genetic switch
Study finds that maternal genes in mice predominate in the developing brain, while paternal genes gain the upper hand in adulthood. Researchers also find 1,300 imprinted genes in the brain, far more than previously known.
