Researchers redesign a compact RNA-guided enzyme from bacteria, making it an efficient editor of human DNA.
Dopamine signals when a fear can be forgotten
Study shows how a dopamine circuit enables mice to extinguish fear after a peril has passed, opening new avenues for understanding and potentially treating fear-related disorders.
Response to infection highlights the nervous system’s surprising degrees of flexibility
Upon infection, the C. elegans worm reshuffles the roles of brain cells and flips the functions of some of the chemicals it uses to regulate behavior.
A brief history of expansion microscopy
Since an MIT team introduced expansion microscopy in 2015, the technique has powered the science behind kidney disease, plant seeds, the microbiome, Alzheimer’s, viruses, and more.
An ancient RNA-guided system could simplify delivery of gene editing therapies
The programmable proteins are compact, modular, and can be directed to modify DNA in human cells.
AI system predicts protein fragments that can bind to or inhibit a target
FragFold, developed by MIT Biology researchers, is a computational method with potential for impact on biological research and therapeutic applications.
When a cell protector collaborates with a killer
New research reveals what it takes for a protein that is best known for protecting cells against death to take on the opposite role.
Killing the messenger
A newly characterized anti-viral defense system in bacteria aborts infection through a novel mechanism by chemically altering mRNA.
MIT affiliates named 2024 HHMI Investigators
Four faculty members and four others with MIT ties are recognized for pushing the boundaries of science and for creating highly inclusive and collaborative research environments.
CHARMed collaboration creates a potent therapy candidate for fatal prion diseases
A new gene-silencing tool shows promise as a future therapy against prion diseases and paves the way for new approaches to treating disease.
