Researchers Discover a Way to Make Proteins Not Found in Nature

Using bacteria, Yale researchers rewrite most of the genetic instructions that encode all 20 amino acids, creating a specific 21st amino acid. Yale researchers have discovered a targeted way to make proteins not generally found in nature by expanding the information encrypted in the genetic code. Working with bacteria, the Yale team rewrote most of […]

Newly Discovered Small Molecule Boosts Insulin Signaling

Harvard Medical School researchers have uncovered a new pathway in insulin resistance and show that a newly discovered small-molecule inhibitor can interrupt this pathway and increase insulin signaling. Insulin resistance unleashes a vicious cycle in Type 2 diabetes whereby excess blood sugar induces the release of yet more insulin by the pancreas. A primary goal […]

Protein GDF 11 Reverses Aging in the Heart

Researchers have identified a protein in the blood of mice and humans that may prove to be the first effective treatment for a form of age-related heart failure, finding in mice that hearts reduced in size and thickness and resembled healthy hearts of younger mice when the protein GDF-11 was injected. Two Harvard Stem Cell […]

A Biological Catalyst Capable of Joining Two Segments of RNA

A newly published study details how researchers turned an ordinary protein into an artificial enzyme, a biological catalyst capable of joining two segments of RNA. Five years ago, a pair of researchers used a clever update on a technique called in vitro evolution – evolution in a test tube – to turn an ordinary protein […]
