Mature muscle cells are long and thin, and they often contain multiple nuclei. The fusion of mononucleated muscle progenitor cells into multinucleated myofibers is an essential step to build skeletal ...

The Royal Swedish Academy of Sciences announced today that HHMI Investigator Carolyn Bertozzi of Stanford University, Morten Meldal of University of Copenhagen, and K. Barry Sharpless of Scripps ...

CRISPR has sparked a renaissance in genome editing. Now, next-generation CRISPR technologies let scientists modify the genome more efficiently and precisely than before. Such tools could one day serve ...

A gene editing tool based on a bacterial toxin can make precise changes to mitochondrial DNA inside cells. Scientists can now precisely edit the genes inside mitochondria, the tiny energy factories ...

A new type of DNA editing enzyme, developed in HHMI Investigator David Liu’s lab, lets scientists directly and permanently change single base pairs of DNA from A•T to G•C. The process could one day ...

The goal of the Hanna H. Gray Fellows Program is to reach, recruit, and retain individuals from the diverse talent pool of early career scientists in the United States. Through their successful ...

Thousands of undergraduate students contribute to new study that broadens understanding of genetic diversity of bacteriophages. Over the last seven years, thousands of undergraduate students have ...

New experiments help explain how the brain speeds up or slows down movement. What if you couldn’t move faster even when you wanted to? Researchers thought that the part of the brain that determines ...

A powerful cell-barcoding technique has helped uncover the different ways in which the genome is packaged in about 100,000 individual mouse cells. This atlas, described by Howard Hughes Medical ...

Flies use visual cues to finesse their mental maps of the environment. Two new studies use virtual reality to show how. In a circular arena, a fruit fly navigates a virtual landscape illuminated by ...

As fish in different parts of the world adapted to live in fresh water, the same sites in the genome were changed time and again. Investigator, Stanford University As fish in different parts of the ...

HHMI researchers have learned to program T cells as if they were “microscopic robots” -- to sense inputs and to respond. Investigator, University of California, San Francisco HHMI researchers have ...
