Megan Molteni of Wired writes that data storage company, Catalog, an MIT spinout that is working on using DNA to store data. Molteni explains that at Catalog, “they’re building a machine that will write a terabyte of data a day, using 500 trillion molecules of DNA.”
60 Minutes correspondent Bill Whitaker sits down with Prof. Feng Zhang, “a scientist at the center of the CRISPR craze,” to help explain how the gene-editing tool works and its potential. “There are about 6,000 or more diseases that are caused by faulty genes,” says Zhang. “The hope is that we will be able to address most if not all of them.”
Led by Prof. Tim Lu, Senti Biosciences has received $53 million in venture capital funding to launch their startup that will focus on cancer therapies, writes Jonathan Shieber for TechCrunch. Ideally, these therapies “are able to be controlled (programmed) at the cellular level and respond to conditions in a variety of ways,” Shieber explains.
MIT researchers have “discovered a slight difference in how humans produce the building blocks of DNA compared to how bacteria does it,” writes Fiona McMillan for Forbes. The comparison of human and bacterial enzymes “bodes well for the possible development of new antibiotics,” explains McMillan.
Researchers at the Broad Institute of MIT and Harvard have programmed CRISPR to “in essence, make edits when significant cellular events occur,” writes Kristin Brown for Gizmodo. “All this adds up to the potential of CRISPR as not just a gene-editing powerhouse, but a multifunctional tool that also works as a biosensor, a medical detective, and an invaluable instrument for basic research.”
Originally created by the Zhang Lab in 2017, CRISPR tool SHERLOCK has been improved upon to be three times more sensitive for detecting viruses and infections using an inexpensive test strip. Sharon Begley writes for STAT News, “A paper strip, like in a pregnancy test, is dipped into a sample, and if a line appears, the target molecule was detected — no instruments required.”
A gene-editing tool called SHERLOCK, developed in Prof. Feng Zhang’s lab, allows for faster detection of infections and viruses, such as Zika and Dengue fever. “It does this by combining different types of CRISPR enzymes, which are unleashed together to target distinct bits of DNA and RNA, another of the major biological molecules found in all forms of life,” writes Alessandra Potenza for The Verge.
MIT scientists have developed a technique that could potentially be used one day to treat diseases of the brain, muscles, liver and kidneys by using CRISPR to edit RNA, writes Melissa Healy for The Los Angeles Times. Making edits to the chemical message of RNA, “doesn’t effect a permanent change in a cell’s architectural plan; rather, it essentially alters the implementation of that plan,” explains Healy.
Prof. Feng Zhang and his colleagues have created a CRISPR-based system that can edit RNA in human cells, reports Amy Dockser Marcus for The Wall Street Journal. “The new RNA-editing system, which the scientists have dubbed Repair, allows the editing of individual RNA letters, correcting a common mutation known to play a role in a number of diseases.”
Financial Times reporter Clive Cookson writes that Prof. Feng Zhang and his colleagues have engineered CRISPR so that it can edit single RNA letters in human cells. Cookson explains that the researchers believe that, “RNA editing offers a safer and more flexible way to make corrections than the permanent changes involved in DNA editing.”
Prof. Feng Zhang has been awarded the Lemelson-MIT Prize, reports Sharon Begley for STAT. Zhang was honored for his, “track record of innovations and of coming up with big ideas that change fields,” explains Prof. Michael Cima, faculty director of the award. “Zhang is one of those individuals who move through groups of talented people sparking new ideas.”
Prof. Feng Zhang has been honored as one of the recipients of this year’s Albany Medical Center Prize in Medicine and Biomedical Research for his work contributing to the development of the gene-editing tool CRISPR-Cas9, according to the AP. The AP notes that CRISPR-Cas9, “has sparked a boom in research over the past five years.”
The Economist writes about new research from Prof. Chris Voigt, in which “he and his colleagues demonstrate how to control customised cells with coloured light.”
TIME reporter Alice Park writes that MIT researchers have modified the CRISPR gene-editing system so that it could be used to diagnose disease. Park explains that the researchers, “used CRISPR to recognize specific substances that bacteria and viruses make. Picking up even the slightest whisper of these products can alert doctors that an infection is active.”
MIT researchers have developed a new technique that uses the CRISPR gene-editing system to diagnose diseases, reports Joel Achenbach for The Washington Post. Achenbach explains that the tool could potentially be used to “detect not only viral and bacterial diseases but also potentially for finding cancer-causing mutations.”
