Boston Globe reporter Sharon Begley writes that Prof. Feng Zhang has uncovered enzymes that could be used to edit genes more precisely than the proteins currently used by CRISPR. Begley explains that the discovery means that CRISPR could become an “even more powerful tool to reveal the genetic defects underlying diseases and to perhaps repair them.”
In an article for Wired, Sarah Zhang writes that MIT researchers have identified a new gene-editing system that could prove more effective than current techniques. The new system involves, “a different protein that also edits human DNA, and, in some cases, it may work even better than Cas9,” the protein used for DNA editing.
Karen Weintraub writes for The Boston Globe about Prof. Ki Ann Goosens’ work examining the intersection of stress and mental illness. Weintraub explains that Goosens’ latest work looks at whether the medications used to treat PTSD make biological sense.
In this video, PBS explores a new technique MIT researchers developed to enlarge brain samples, making them easier to image at high resolutions. Prof. Ed Boyden explains that he hopes the technique could be used to “hunt down very rare things in a tissue.”
Writing for the Huffington Post, Dr. Sandra Bond Chapman highlights an MIT study that shows different mental processes peak at different ages. The study “examined a number of different brain processes that make up intelligence, rather than viewing intelligence as a single measure as has traditionally been done.”
Professor Edward Gibson speaks on Huffington Post Live about his research, which indicates that all human languages share a common link. “It turns out that across all languages people tend to put the words that go together to make the bigger phrases close together linearly in the sentences,” said Gibson.
MIT researchers have found that different parts of the human brain work best at different ages, reports Susan Pinker for The Wall Street Journal. “Some abilities mature early, such as how fast we recall names and faces. Others, like vocabulary and background knowledge, are late bloomers,” Pinker explains.
Karen Weintraub writes for The Boston Globe about Prof. Susumu Tonegawa’s research examining how triggering happy memories could help alleviate depression. “When that kind of technology is invented,” Tonegawa explains, “it could potentially become very powerful therapy.”
In an article for Bloomberg Business about how poverty can impact brain development in children, John Tozzi highlights research by Prof. John Gabrieli examining how family income can affect academic achievement. "It’s only in the last few years that there’s been any systematic research asking about the biological side of the story," explains Gabrieli.
MIT researchers have found that nitrous oxide or laughing gas is a stronger anesthetic than previously believed, writes Nitya Rajan for The Huffington Post. The researchers found that nitrous oxide caused changes in patient brainwaves and a pattern of electrical firing across the brain.
New research by Prof. Susumu Tonegawa presents the possibility that depression can be alleviated by recalling happy memories, reports Clive Cookson for The Financial Times. The findings suggest, "new ways to treat depression by manipulating memory neurons.”
MIT researchers were able to reverse depression-like behavior by reactivating happy memories, writes Carolyn Gregorie for The Huffington Post. Graduate student and lead author Steve Ramirez “hopes that scientists will one day find a way to prevent depressive symptoms from occurring in the first place.”
Professor Susumu Tonegawa’s research group has found that artificially stimulating positive memories can ease depression, reports Jonathan Webb for BBC News. Webb explains that the research “demonstrates the power of rekindling happy memories.”
Prof. Ki Goosens is investigating how the gherlin hormone could possibly be used to develop a vaccine for PTSD, reports Bree Sison for CBS Boston. “If we can pick even just one mental illness and improve the outcome for people who suffer from it, I’d be happy,” says Goosens.
Jessica Hamzelou writes for New Scientist that MIT researchers have been able to recover memories using light. The technique could eventually be used to help people with Alzheimer’s or amnesia. Hamzelou writes that Prof. Susumu Tonegawa, hopes to “develop a way to reactivate forgotten memories in people before the brain tissue itself is damaged, as is often the case in dementia.”
