MIT researchers have discovered an RNA-guided DNA-cutting enzyme in eukaryotes, reports Science. “The researchers speculate that eukaryotic cells may have gained the newly identified editing genes from transposable elements—so-called jumping genes—they received from bacteria,” writes Science.
MIT researchers have identified a new biological editing system that could “potentially be even more precise than CRISPR gene editing,” reports Laura Baisas for Popular Science. The new system, based on a protein called Fanzor, is “the first programmable RNA-guided system discovered in eukaryotes,” Baisas notes.
Researchers at MIT have developed a new nanoparticle sensor that can detect cancerous proteins through a simple urine test. “The researchers designed the tests to be done on a strip of paper, similar to the at-home COVID tests everyone became familiar with during the pandemic,” writes Lambert. “They hope to make it as affordable and accessible to as many patients as possible.”
Researchers at MIT have developed new gene-editing technology that can move large sequences of DNA into the human genome, reports Ryan Cross for The Boston Globe. “The molecular tool gives scientists a new way to completely replace broken genes, paving the way to potential cures for diseases such as cystic fibrosis,” writes Cross.
A study co-authored by researchers from MIT found that a person’s ancestry can impact CRISPR’s ability to edit genomes as intended, “particularly in people of African descent, whose genomes are most likely to differ from those used to steer CRISPR to a specific gene,” reports Jocelyn Kaiser for Science.
Nature reporter Eric Bender spotlights MIT startup Kytopen, which has developed a microfluidic platform to create induced pluripotent stem (iPS) cells and other forms of cell therapy. We want to do minimally invasive surgery,” says Kytopen co-founder Prof. Cullen Buie.
UPI reporter Brooks Hays writes that a new tool developed by researchers from MIT and other institutions can precisely control gene expression without altering the underlying gene sequence. “Scientists hope this new ability to silence any part of the human genome will lead to powerful insights into functionality of the human genome, as well as inspire new therapies for a variety of diseases and genetic disorders,” writes Hays.
Prof. Kevin Esvelt writes for The Boston Globe about the need for transparency surrounding gene-editing research. “We should establish transparent, publicly accessible standards to help determine whether, when, and how research that could impact everyone should proceed,” Esvelt explains.
A CRISPR-based diagnostic test for Covid-19 developed by researchers from MIT and the Broad Institute could produce results within an hour, reports Deborah Becker for WBUR. "Using these technologies will really allow for much more rapid testing — down from days to sometimes less than an hour," said McGovern fellow Jonathan Gootenberg. "That would enable a drastic change in how the tracing and handling of the pandemic is done."
A new center established at the McGovern Institute for Brain Research is aimed at accelerating the development of novel therapies and technologies, writes Katie Jennings for Forbes. The hope is that “we can identify common pathways, either a common molecular pathway that's a chokepoint for a therapy or a common group of neurons or neural systems,” says Prof. Robert DeSimone, director of the McGovern Institute.
Boston Globe reporter Felice Freyer writes about the K. Lisa Yang and Hock E. Tan Center for Molecular Therapeutics in Neuroscience, which was established at the McGovern Institute for Brain Research thanks to a $28 million gift from philanthropist Lisa Yang and MIT alumnus Hock Tan ’75. “The center will develop tools to precisely target the malfunctioning genes and neurons underpinning brain disorders,” writes Freyer.
WBUR’s Carey Goldberg explores how MIT researchers developed a new CRISPR-based research tool that can be used to detect Covid-19. "A lot of things that we try fail," says research scientist Jonathan Gootenberg. "And that’s OK. Because sometimes you find these things that are really, really awesome."
Reporting for WBUR, Carey Goldberg highlights how MIT researchers have developed a new RNA editing tool that could be used to tweak a gene that raises the risk of Alzheimer’s disease. As the effects of RNA editing are not permanent, “it's almost like a small, pill-like version of gene therapy,” explains research scientist and McGovern Fellow Omar Abudayyeh.
Axios reporter Eileen Drage O’Reilly highlights how Prof. Feng Zhang and his colleagues have developed a new system that uses “jumping genes” to improve the accuracy of gene editing. “This is filling a gap we couldn't address before, to be able to insert DNA into the genome," says Zhang of the ability to insert large genomes in a directed way.
Researchers from MIT and other institutions have developed a new model for autism research that could enable new therapies and treatments, reports the Xinhua news agency. The model could “provide a basis for a deeper understanding of the neurobiological mechanisms of autism and the development of more transformative therapeutics.”
