Life, with another ingredient
In a paper published in PNAS, Jack W. Szostak, professor of chemistry and chemical biology at Harvard, along with graduate student Seohyun (Chris) Kim, suggest that RNA could have started with a different set of nucleotide bases. In place of guanine, RNA could have relied on a surrogate, inosine.

Neurons at work
Using genetic tools to implant genes that produce fluorescent proteins in the DNA of transparent C. elegans worms, Harvard scientists have been able to shed light on neuron-specific “alternative splicing,” a process that allows a single gene to produce many different proteins.

A shot against heart attacks?
Harvard Stem Cell Institute scientists collaborating with researchers at the University of Pennsylvania have developed a “genome-editing” approach for permanently reducing cholesterol levels in mice through a single injection, a development with the potential to reduce the risk of heart attacks in humans by 40 to 90 percent.

A foundation for future research
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 first, scientists develop tiny implantable biocomputers
Researchers at Harvard and Princeton universities have taken a crucial step toward building biological computers, tiny implantable devices that can monitor the activities and characteristics of human cells. The information provided by these “molecular doctors,” constructed entirely of DNA, RNA, and proteins, could eventually revolutionize medicine by directing therapies only to diseased cells or tissues.
