MIT researchers have identified the brain circuit required for observational learning, reports Xinhua. According to the study, the area involved in evaluating social information is more active when witnessing an experience and “relays information about the experience” to the region important for processing emotions.
A new paper co-authored by Prof. Omer Yilmaz and Prof. David Sabatini found that fasting substantially “improves stem cells' ability to regenerate,” reports Xinhua. The researchers hope this finding could lead to new drug treatments that “stimulate regeneration without requiring patients to fast, which is difficult for most people.”
New research suggests “children are highly skilled at learning the grammar of a new language up until the age of 17 or 18, much longer than previously thought,” reports Kashmira Gander in Newsweek. “We may need to go back to the drawing board in trying to explain why adults have trouble learning language,” Joshua Hartshorne, who co-wrote the study as a postdoc at MIT, tells Gander.
A study co-authored by Prof. Josh Tenenbaum finds that learning a new language should start before age 10 to achieve a native-like grasp of the grammar, reports BBC News. People remain highly skilled language learners until about 17 or 18, but then fall off, which Tenenbaum says could be due to “a biological change” or “something social or cultural.”
MIT researchers have developed “the first artificial system to mimic the way the brain interprets sound – and it rivals humans in its accuracy,” reports Samia Bouzik for NOVA Next. “The research offers a tantalizing new way to study the brain…[and] could boost some neuroscience research into the fast track,” writes Bouzik.
Research published in Science Translational Medicine suggests that inflammation caused by tumor removal surgery may actually encourage the emergence of new tumors. Daniel Uria for UPI reports that the study, led by Prof. Robert Weinberg, identified “perioperative anti-inflammatory treatment” as a way to substantially reduce the likelihood of “early metastatic recurrence in breast cancer patients.”
New research from MIT and the Whitehead Institute suggests that “the body’s own mechanism for healing” may cause cancerous cells to spread after breast cancer-related surgeries, reports Karen Weintraub for WBUR CommonHealth. “The post-surgical wound-healing response somehow releases…cells that have already spread to distant sites in the body,” explains Prof. Robert Weinberg, “releasing them from the constraints that have previously prevented them from growing actively.”
Jenny Anderson of Quartz describes a new study from MIT’s McGovern Institute and others showing that back-and-forth banter proved much more predictive of a child’s language development than the number of words spoken to them. “[MIT graduate student Rachel] Romeo and her colleagues believe that these conversational turns help to actually rewire and grow kids’ brains,” writes Anderson.
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 have found a way to reactivate the gene that causes fragile X syndrome, the most common inherited form of intellectual impairment. “The team used an emerging technique called “epigene-editing”,” writes Alice Klein for New Scientist, which is reversible. “That means any off-target effects could be fixed and wouldn’t be passed to future generations.”
A new study from the McGovern Institute suggest “that one of the most effective ways to stimulate children’s brains from a young age is back-and-forth conversation,” writes Elise Takaham for The Boston Globe. “We think that it’s because back-and-forth conversation is not only about hearing more words, it’s also about practicing paying attention to someone else and involves lots of emotional and social bonding,” said Prof. John Gabrieli.
A study by MIT scientists has identified the neurons that fire at the beginning and end of activities, which is important for initiating a routine. “This task-bracketing appears to be important for initiating a routine and then notifying the brain once it is complete,” Prof. Ann Graybiel told Xinhua.
Boston Herald reporter Lindsay Kalter writes that a team of MIT researchers has developed a new technique that can deliver medication to specific regions of the brain with extreme precision. “The whole idea here is that instead of treating the entire brain, you can treat small portions of the brain,” explains Prof. Michael Cima.
AP reporter Lauran Neergaard writes that MIT researchers have developed a hair-thin implant that can deliver medications to specific regions of the brain. Neergaard writes that the device, “could mark a new approach to treating brain diseases — potentially reducing side effects by targeting only the hard-to-reach circuits that need care.”
MIT researchers have developed a new capsule that allows HIV medication to be delivered over the course of a week, and could allow patients to forgo daily pills, reports Ed Cara for Gizmodo. Researchers also found that using this method for the pre-exposure pill, “would manifest in approximately a 20 per cent increase in efficacy” for weekly dosage compared to the daily regimen.
