MIT News
MIT News is dedicated to bringing news from the Massachusetts Institute of Technology (MIT) to the world. We cover research, innovation, teaching, entrepreneurship, and the Institute’s distinctive and quirky culture. We find ourselves educated and amazed by our community of hands-on problem-solvers who are eager to know how things work — and inspired to make them work better. We hope you are amazed, too.

Audio Article: Babies can tell who has close relationships based on one clue: saliva
MIT neuroscientists have identified a specific signal that young children and even babies can use to determine whether two people have a strong relationship and a mutual obligation to help each other: whether those two people kiss, share food, or have other interactions that involve sharing saliva.

Audio Article: Deploying machine learning to improve mental health
A machine-learning expert from MIT and a psychology researcher/clinician from Massachusetts General Hospital (MGH) have teamed up to develop tools for mental health care delivery. They hope that their algorithms will eventually equip physicians and patients with useful information about individual disease trajectory and effective treatment.

Audio Article: Reducing food waste to increase access to affordable foods
Spoiler Alert, a company founded by two MIT alumni, is helping companies bridge the gap between food waste and food insecurity with a platform connecting major food and beverage brands with discount grocers, retailers, and nonprofits. The platform helps brands discount or donate excess and short-dated inventory days, weeks, and months before it expires.

Audio Article: Scientists build new atlas of ocean’s oxygen-starved waters
A team of MIT scientists have generated a detailed, three-dimensional "atlas" of the largest oxygen-deficient zones (ODZ) in the tropical Pacific. And though these ODZs make up less than 1 percent of the ocean’s total volume, they are a significant source of nitrous oxide, a potent greenhouse gas.

Audio Article: Sensor based on quantum physics could detect SARS-CoV-2 virus
A novel approach to testing for the presence of the virus that causes Covid-19 may lead to tests that are faster, less expensive, and potentially less prone to erroneous results than existing detection methods. Though the work, based on quantum effects, is still theoretical, these detectors could potentially be adapted to detect virtually any virus, the researchers say.

Audio Article: Giving robots social skills
MIT researchers have now incorporated certain social interactions into a framework for robotics, enabling machines to understand what it means to help or hinder one another, and to learn to perform these social behaviors on their own.

Audio Article: Dragging your feet? Lack of sleep affects your walk, new study finds
Good sleep can be hard to come by. But a new study by researchers at MIT and the University of São Paulo in Brazil finds that if you can make up for lost sleep, even for just a few weekend hours, the extra zzz’s could help reduce fatigue-induced clumsiness, at least in how you walk.
