This fiery golden wheel is an artery running through the thymus of a monkfish. The thymus is an organ in the lymphatic system that is a nursery for certain immune cells.The artery you can see here ...

What am I looking at? This video captures two cultured mouse skeletal muscle progenitor cells undergoing fusion. The actin protein is labeled in green, and the myosin protein is labeled in red. You ...

The development of ingenious tools for building new molecules has earned three scientists the 2022 Nobel Prize in Chemistry. Carolyn Bertozzi, a Howard Hughes Medical Institute (HHMI) Investigator at ...

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 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 ...

Over the last seven years, thousands of undergraduate students have joined the effort to sequence and analyze the genomes of bacteria-infecting viruses as part of the Howard Hughes Medical Institute’s ...

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 ...

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 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 ...

For their latest study, Kingsley, scientists from the Broad Institute of MIT and Harvard, and an international team of collaborators started by sequencing the genome of an Alaskan freshwater ...

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 ...

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 ...
