Cognito Therapeutics, an MIT startup co-founded by Prof. Li-Huei Tsai and Prof. Ed Boyden, has developed a headset that uses light and sound to slow the cognitive decline in Alzheimer’s patients, reports Emily Mullin for Wired. “Cognito’s headset, dubbed Spectris, delivers flashing lights and sounds through a pair of connected glasses and headphones to stimulate gamma waves in the brain” writes Mullin. “Different types of brain waves have different paces, or frequencies. Gamma waves are fast-frequency brain waves associated with thinking skills and memory, and people with Alzheimer’s are known to have fewer of these fast brain waves.”

As a research assistant at MIT, Ai Hasegawa designed a project meant to help same-sex couples have a baby that shares both parents’ DNA, writes Jacqui Palumbo for CNN. “With progressing stem cell research and technology – such as the gene-editing technique CRISPR – it is only a matter of time,” writes Palumbo.

MIT researchers have uncovered a potential link between a high-fat diet and increased risk of many types of cancer, reports Chukwuma Muanya for The Guardian. Muanya explains that the study “reveals the effect that a high-fat diet has on the biology of stem cells… and how this might make cancer more likely.”

Researchers at the Koch Institute have been taking steps to find a possible cure for type 1 diabetes. Holly Ellyatt of CNBC writes that the team has developed a device to prevent “implanted insulin-producing cells from being attacked by the immune system for six months.”

In an article for Science, Jocelyn Kaiser writes about how Prof. Robert Weinberg’s company, Verastem Inc., is starting a new round of clinical trials to test the theory that by targeting cancer stem cells, the disease can be controlled.
