Newsweek reporter Joseph Frankel writes that MIT researchers have found that the brain relies on a network of neurons to keep track of time. The researchers found that, “neurons appear to fire in a similar pattern, whether operating at fast or slow speeds...But interestingly, the same patterns stretch or compress over time, depending on the rate of the task.”
MIT researchers have found that a network of neurons compress or stretch their activity in order to control the brain’s timing, reports Alyssa Meyers for The Boston Globe. “Instead of passively waiting for a clock to reach a certain point, the team found the system of neurons changes its state independently based on the action being performed.”
A new study by MIT researchers shows how stress can lead people to make risky decisions, reports Kristin Hugo for Newsweek. “The study lends insights into how neurological disorders affect people. It could be the stress of dealing with inabilities to function properly and staving off cravings, compounded with the chemical effects on the brain, that are influencing people’s uninhibited behavior.”
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.”
Scientific American reporter Lindsay Brownell writes that MIT researchers have developed a technique to enlarge pathology samples. “Not only are expanded samples easier to see because they are larger and more transparent, fluorescent tags and other labels can also be added to track individual molecules of interest.”
A study by MIT researchers finds that children from lower-income families benefited more from summer reading programs, reports Andrew Grant for The Boston Globe. Of the children who participated in the study about half, “improved their test scores and most of those that did came from lower-income families.”
NBC News reporter Maggie Fox writes that MIT researchers have developed a noninvasive brain stimulation technique that could eventually offer relief to patients with diseases like Parkinson’s and epilepsy without requiring surgery. Fox explains that the method allows for sending, “electrical signals deep into the brain without affecting the layers in between.”
MIT researchers have developed a noninvasive method to stimulate specific neurons deep in the brain that could be used to help treat patients with diseases such as Parkinson’s, reports Meredith Wadman for Science. This new method could also allow scientists to “selectively prod deep-brain neurons into action,” explains Wadman.
Writing for Wired, Abigail Beal highlights how MIT researchers have developed a noninvasive technique to trigger reactions in deep brain cells using low frequency electrical signals. “If we could noninvasively stimulate deep regions, without hitting overlying regions, we might be able to help more people because we could stimulate deep regions selectively, without needing surgery,” explains Prof. Ed Boyden.
New York Times reporter Pam Belluck writes that MIT researchers have developed a new, non-invasive deep brain stimulation technique. The technique could be used to help treat, “a range of neurological and psychiatric disorders more cheaply and safely than current approaches,” writes Belluck.
MIT researchers have developed a non-invasive technique for deep brain stimulation, which could be used to help patients with brain diseases, reports Mo Costandi for The Guardian. “Targets for disorders such as depression, Alzheimer’s, PTSD, and so forth, are deep in the brain, and they might be more selectively stimulatable with our method,” says Prof. Ed Boyden.
