The nervous system works because neurons communicate across connections called synapses. They “talk” when calcium ions flow through channels into “active zones” that are loaded with vesicles carrying molecular messages. The electrically charged calcium causes vesicles to “fuse” to the outer membrane of presynaptic neurons, releasing their communicative chemical cargo to the postsynaptic cell. In a new study, scientists at The Picower Institute for Learning and Memory at MIT provide several revelations about how neurons set up and sustain……

The largest graduate residence on MIT’s campus, Sidney-Pacific (Building NW86), also known as Sid-Pac, thrives on the community its residents have built over the past 20 years. Opened in 2002, the residence hall celebrated its 20th anniversary this year with a reunion featuring cookouts, games, and alumni events. Located in the northwest corner of campus, Sid-Pac offers housing to nearly 750 graduate students from all over the world. The community prides itself on being inclusive, diverse, and a multicultural……

Using nanoparticles to deliver cancer drugs offers a way to hit tumors with large doses of drugs while avoiding the harmful side effects that often come with chemotherapy. However, so far, only a handful of nanoparticle-based cancer drugs have been FDA-approved. A new study from MIT and Broad Institute of MIT and Harvard researchers may help to overcome some of the obstacles to the development of nanoparticle-based drugs. The team’s analysis of the interactions between 35 different types of……

Silicon is one of the most abundant elements on Earth, and in its pure form the material has become the foundation of much of modern technology, from solar cells to computer chips. But silicon’s properties as a semiconductor are far from ideal. For one thing, although silicon lets electrons whizz through its structure easily, it is much less accommodating to “holes” — electrons’ positively charged counterparts — and harnessing both is important for some kinds of chips. What’s more,……

It’s another case of a class project that turned into a bit more than the typical assignment.  The story began last fall in the MIT course 6.810 (Engineering Interactive Technologies) taught by Stefanie Mueller, an associate professor in MIT’s Department of Electrical Engineering and Computer Science. The students, who were mostly undergraduates, were asked to do a final group project, and they were assisted in this effort by graduate students who were helping Mueller teach the course.  Now, the……

Microplastics, tiny particles of plastic that are now found worldwide in the air, water, and soil, are increasingly recognized as a serious pollution threat, and have been found in the bloodstream of animals and people around the world. Some of these microplastics are intentionally added to a variety of products, including agricultural chemicals, paints, cosmetics, and detergents — amounting to an estimated 50,000 tons a year in the European Union alone, according to the European Chemicals Agency. The EU……

When high school senior Tuba Balta emailed MIT Plasma Science and Fusion Center (PSFC) Director Dennis Whyte in February, she was not certain she would get a response. As part of her final semester at BASIS Charter School, in Washington, she had been searching unsuccessfully for someone to sponsor an internship in fusion energy, a topic that had recently begun to fascinate her because “it’s not figured out yet.” Time was running out if she was to include the internship as……
