Professor Hal Abelson has dedicated his career to making information technology more accessible to all and empowering people — kids, in particular — through computer science. But his storied career in computer science began with Abelson coming to MIT in 1969 to pursue his interest in mathematics. “The thing I like to remind students of is that they don’t have to know what they are going to do with the rest of their life,” Abelson says. “I get a……

Swirling around the planet’s equator, the rings of Saturn are a dead giveaway that the planet is spinning at a tilt. The belted giant rotates at a 26.7-degree angle relative to the plane in which it orbits the sun. Astronomers have long suspected that this tilt comes from gravitational interactions with its neighbor Neptune, as Saturn’s tilt precesses, like a spinning top, at nearly the same rate as the orbit of Neptune. But a new modeling study by astronomers……

If you have a LinkedIn account, your connections probably consist of a core group of people you know well, and a larger set of people you know less well. The latter are what experts call “weak ties.” Now a unique, large-scale experiment co-directed by an MIT scholar shows that on LinkedIn, those weak ties are more likely to land you new employment, compared to your ties with people you know better. “When we look at the experimental data, weak……

Say you live across from a bakery. Sometimes you are hungry, and therefore tempted when odors waft through your window, but other times satiety makes you indifferent. Sometimes popping over for a popover seems trouble-free, but sometimes your spiteful ex is there. Your brain balances many influences in determining what you’ll do. A new MIT study details an example of this working in a much simpler animal, highlighting a potentially fundamental principle of how nervous systems integrate multiple factors……

NASA’s James Webb Space Telescope (JWST) is revealing the universe with spectacular, unprecedented clarity. The observatory’s ultrasharp infrared vision has cut through the cosmic dust to illuminate some of the earliest structures in the universe, along with previously obscured stellar nurseries and spinning galaxies lying hundreds of millions of light years away. In addition to seeing farther into the universe than ever before, JWST will capture the most comprehensive view of objects in our own galaxy — namely, some……

Pharmaceutical companies make some remarkable advances. Could they make significantly more of them? It’s possible, but for that to happen, the industry would likely have to change some of its core habits, according to the research of Danielle Li, an associate professor of economics at the MIT Sloan School of Management. In a recent paper, Li, along with economists Joshua Krieger and Dimitris Papalikolaou, found that big pharma firms are risk-averse. Novel drugs can have big payoffs, but firms……

Betar Gallant, MIT associate professor and Class of 1922 Career Development Chair in Mechanical Engineering, grew up in a curious, independently minded family. Her mother had multiple jobs over the years, including in urban planning and in the geospatial field. Her father, although formally trained in English, read textbooks of all kinds from cover to cover, taught himself numerous technical fields including engineering, and worked successfully in them. When Gallant was very young, she and her father did science……
