The average American throws out around 81 pounds of clothing each year, and there are few options for recycling it. MIT engineers hope to cut down on that textile waste with a new type of yarn. The thermoplastic yarn mimics the properties of conventional elastic yarns, which typically combine spandex with polyester or nylon. Those...

A high-fat, low-carbohydrate diet can help some people lose weight, and some research has shown that it may protect against colon cancer. But a new study suggests that such a ketogenic diet may also increase the risk of cancer in the small intestine. This type of diet forces the body to burn fatty acids instead...

Strokes leave 5 million people with long-term impairments each year, and a growing shortage of physical therapists makes it hard for them to get the care they need. A new approach tries to solve that problem by combining artificial intelligence and human therapy. Johannes Lachner, a former MIT postdoc who is now an assistant professor...

These are images of quizzes I took in 3.091, Introduction to Solid-State Chemistry, in the fall of 1980. One is my very first exam at MIT, and getting 49 out of 100 was a soul-crushing experience. I can still picture the TA, Leszek Pawlowicz, PhD '87, returning my paper. He had a big smile on...

In corporate America, Stanley Anderson '79 says, executives often assume that their peers grew up in privileged circumstances. He did not. I spent my early years trying not to get recruited into gangs, getting shot at, watching my friends get murdered, and thinking that if I don't leave, I will die," says Anderson, who was...

Alissa Totman '13 was a sophomore when she joined MIT BrainTrust, a student-run organization that connects Institute undergraduates and people with brain injuries for support and socializing. That group was a great way to learn about the human experience of what people go through when they experience a brain injury," she says. And it laid...

Growing up on a small farm in Nebraska, Megan Donahue '85 discovered the wider world by reading her way through her local library.
