Harvard researchers recently developed the most detailed “specificity profile” for Cas9 — a “machine” made of protein and RNA that can be programmed to target specific DNA sequences and to precisely cut, paste, and turn on or turn off genes. Future researchers will use the data when developing genetic tools and therapies.

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 dramatic changes in an organism — or is it the result of many smaller changes over time?
For decades, scientists wondered whether there was some subtle difference between parts of the genetic code that, while different, appear to encode the same amino acid. Harvard researchers now have the answer.
Scientists at Harvard have pioneered a breakthrough technique that can reproduce an individual’s entire genome from a single cell. The development could revolutionize everything from cancer treatment, by allowing doctors to obtain a genetic fingerprint of a person’s cancer early in treatment, to prenatal testing.
Geneticist Elaine Ostrander runs a comparative-genomics lab that examines dog DNA to understand better the traits that might aid understanding of human diseases.
Most of the DNA alterations that are tied to disease do not alter protein-coding genes, but rather the “switches” that control them. Characterizing these switches is one of many goals of the Encyclopedia of DNA Elements (ENCODE) project.
Research led by scientists at Harvard and University College London has shown that Native Americans arrived in three waves of migration, not one, as is commonly held and that at least one group returned home to Asia.

Researchers at Harvard’s Wyss Institute for Biologically Inspired Engineering have figured out how to use short lengths of DNA as physical, rather than genetic, building blocks, creating letters and other shapes from the molecules in a proof of design that could one day lead to the creation of structures that, among other things, deliver drugs to disease sites.

As reported in the online version of Nature Structural & Molecular Biology on Feb. 5, researchers have produced 3-D images of the protein system that works to repair DNA. The images reveal that the proteins can actually alter their shape in what amounts to a genetic “pat-down,” or a way for the mechanism to identify areas of the genetic code that need repair.
Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have developed a robotic device made from DNA that could potentially seek out specific cell targets within a complex mixture of cell types and deliver important molecular instructions, such as telling cancer cells to self-destruct or programming immune responses.
As science wrestles with the problem of how life arose on Earth, hindsight shows that seemingly intractable obstacles can have simple, even elegant solutions, said Nobel laureate Jack Szostak.

Scientists at Harvard-afilliated Dana-Farber Cancer Institute and the Broad Institute have found strikingly high levels of a bacterium in colorectal cancers, a sign that it might contribute to the disease and potentially be a key to diagnosing, preventing, and treating it.
Looking at large samples, an international consortium — that included involvement by scientists at the Broad Institute of Harvard and MIT and Harvard-affiliated Massachusetts General Hospital (MGH) — has identified 10 genetic risk factors that contribute to either schizophrenia or bipolar disorder and discovered strong evidence for three genes being implicated in both diseases.
An international team of researchers studying DNA patterns from modern and archaic humans has found that the Denisovans, a recently discovered hominin group, contributed genes to several populations in Asia and that modern humans settled Asia in more than one migration.
Scientists at Harvard-affiliated Dana-Farber Cancer Institute have successfully disrupted the function of a cancer gene involved in the formation of most human tumors by tampering with the gene’s “on” switch and growth signals, rather than targeting the gene itself.

By comparing the DNA of modern elephants from Africa and Asia to DNA extracted from two extinct species, the woolly mammoth and the mastodon, researchers have concluded that Africa has two — not one — species of elephant. Now that we know the forest and savanna elephants are two very different animals, the forest elephant should become a bigger priority for conservation purposes.
