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.”
MIT researchers have developed a new technique for making vaccines using freeze-dried cells, reports Ed Yong for The Atlantic. Yong explains that in addition to producing medicines, the technique provides a new way of “detecting important diseases, like Zika and Ebola, without relying on laboratories or sequencing machines.”
Eric Boodman writes for STAT that MIT researchers have developed a technique to produce biopharmaceuticals in remote locations. “Instead of making the drugs and then trying to keep them refrigerated over thousands of miles,” Boodman writes, the researchers, “want to give people the ingredients. These components don’t require refrigeration, and the instructions are as simple as they come: Just add water.”
Prof. Kevin Esvelt and his team at the Media Lab hope to make gene drives safer by splitting genes into three or more elements, writes New Scientist. “If it works, it could allow a gene drive to be tested locally, to combat malaria, say, without spreading to other cities,” the article notes.
New Scientist reporter Colin Barras writes that MIT researchers have found they can program C2c2, an enzyme found in bacteria, to serve as an RNA-editing tool. Barras writes that the tool “promises to transform our understanding of RNA’s role in our growth and development, and provide a new avenue for treating infectious diseases and cancer.”
MIT researchers have developed a programming language that allows users to design DNA circuits for living cells, writes Andy Coghlan for New Scientist. “We take the same approach as for designing an electronic chip,” says Prof. Christopher Voigt. “Every step in the process is the same – it’s just that instead of mapping the circuit to silicon, it’s mapped to DNA.”
Christopher Intagliata reports for Scientific American about the programming language Prof. Christopher Voigt’s team developed for living cells. Intagliata explains that, “the researchers used the platform to design 60 genetic circuits, which they then ran inside E. coli bacteria. Many of these DNA-based circuits allow bacteria to sense environmental data…and respond in various ways.”
