Study: The ozone hole is healing, thanks...
A new MIT-led study confirms that the Antarctic ozone layer is healing, as a direct result of global efforts to reduce ozone-depleting substances. Scientists including the MIT team have observed signs of ozone recovery in the past. But the new study is the first to show, with high statistical confidence, that this recovery is due primarily to the reduction of ozone-depleting substances, versus other influences such as natural weather variability or increased greenhouse gas emissions to the stratosphere. “There’s been...

Developing materials for stellar performance in fusion...
When Zoe Fisher was in fourth grade, her art teacher asked her to draw her vision of a dream job on paper. At the time, those goals changed like the flavor of the week in an ice cream shop — “zookeeper” featured prominently for a while — but Zoe immediately knew what she wanted to put down: a mad scientist. When Fisher stumbled upon the drawing in her parents’ Chicago home recently, it felt serendipitous because, by all measures,...

Letterlocking: A new look at a centuries-old...
For as long as people have been communicating through writing, they have found ways to keep their messages private. Before the invention of the gummed envelope in 1830, securing correspondence involved letterlocking, an ingenious process of folding a flat sheet of paper to become its own envelope, often using a combination of folds, tucks, slits, or adhesives such as sealing wax. Letter writers from Erasmus to Catherine de’ Medici to Emily Dickinson employed these techniques, which Jana Dambrogio, the...

Designing better ways to deliver drugs
When Louis DeRidder was 12 years old, he had a medical emergency that nearly cost him his life. The terrifying experience gave him a close-up look at medical care and made him eager to learn more. “You can’t always pinpoint exactly what gets you interested in something, but that was a transformative moment,” says DeRidder. In high school, he grabbed the chance to participate in a medicine-focused program, spending about half of his days during his senior year in...

Seeing more in expansion microscopy
In biology, seeing can lead to understanding, and researchers in Professor Edward Boyden’s lab at the McGovern Institute for Brain Research are committed to bringing life into sharper focus. With a pair of new methods, they are expanding the capabilities of expansion microscopy — a high-resolution imaging technique the group introduced in 2015 — so researchers everywhere can see more when they look at cells and tissues under a light microscope. “We want to see everything, so we’re always...

Faces of MIT: Michele David
Michele David has had a long and varied career in medicine. But, she says, it took coming to MIT nine years ago to find “a job that fully engages all of who I am.” David, a highly accomplished physician, currently serves as chief of clinical quality and patient safety at MIT Health, the Institute’s multispecialty group practice and health resource serving the MIT community — including students, faculty, and staff, as well as affiliated families and retirees. While she...

Will neutrons compromise the operation of superconducting...
High-temperature superconducting magnets made from REBCO, an acronym for rare earth barium copper oxide, make it possible to create an intense magnetic field that can confine the extremely hot plasma needed for fusion reactions, which combine two hydrogen atoms to form an atom of helium, releasing a neutron in the process. But some early tests suggested that neutron irradiation inside a fusion power plant might instantaneously suppress the superconducting magnets’ ability to carry current without resistance (called critical current),...

Sometimes, when competitors collaborate, everybody wins
One large metropolis might have several different train systems, from local intercity lines to commuter trains to longer regional lines. When designing a system of train tracks, stations, and schedules in this network, should rail operators assume each entity operates independently, seeking only to maximize its own revenue? Or that they fully cooperate all the time with a joint plan, putting their own interest aside? In the real world, neither assumption is very realistic. Researchers from MIT and ETH...

Rebuilding Ukraine
Nearly three years after Russian military forces invaded Ukraine, escalating a decade-long conflict, Ukrainian cities lie in ruin as the war drags on. The seaside city of Mariupol was particularly hard hit. Bombs hollowed out hospitals and homes and leveled banks and playgrounds. Schools sit charred and empty. The remaining 30 percent of the population still residing in Mariupol, now under Russian occupation, lack reliable electricity, clean water, and medical care. And of the 65,000 Mariupolites in exile across Ukraine and...
