Brian Sietsema has a favorite word. It's somewhat surprising that he can choose just one. He's the person spellers rely on to confirm pronunciations and answer questions about the roots of the words they're given at the Scripps National Spelling Bee-arguably the world's most prestigious competition of its kind. The story of how the word...

The national conversation about the value of education is currently dominated by speculation about the risks and positive potential of AI. Whatever your own perspective on that debate, I hope you'll be glad to know that MIT is also working on a deeply important but comparatively old-fashioned challenge: American high school students' startlingly uneven access...

With an adaptable fastener designed at CSAIL, pitching a tent or adjusting the cast for a broken bone could be almost as easy as zipping your coat. The researchers, led by associate professor Stefanie Mueller, were inspired by an abandoned prototype for a three-sided zipper that William Freeman, PhD '92 (now an MIT professor), patented...

Our hands are the nimblest parts of our bodies, coordinating 34 muscles, 27 joints, and over 100 tendons and ligaments to perform countless nuanced movements and gestures. So far, robots have been notoriously bad at mimicking that dexterity, in part because researchers struggle to capture what is actually going on under our skin in order...

MIT engineers have found the first direct evidence that plant seeds can sense sounds in nature: Rice submerged in shallow water germinated 30% to 40% more quickly when exposed to vibrations from water dripping on the surface. They think other types of seeds may respond similarly. When a raindrop hits a puddle's surface or the...

A technology developed by Professor Sangeeta Bhatia, SM '93, PhD '97, and colleagues could offer new hope to the thousands of Americans with chronic liver disease who are waiting for an organ transplant or not strong enough to tolerate one. The liver is involved in regulating blood clotting, removing bacteria from the bloodstream, metabolizing drugs,...

With a test being developed at MIT, diagnosing pneumonia and other lung conditions could someday be as easy as breathing into a tube. The test, dubbed PlasmoSniff, is a portable, chip-scale sensor that traps and detects biomarkers, synthetic compounds indicating disease. The idea is that a person would first breathe in nanoparticles that are specially...

Rob Morris, SM '09, PhD '15, didn't know where to turn when he first felt symptoms of depression as a teenager: I had no exposure to healthy coping strategies. I had no vocabulary for what was happening to me." That experience, he says, has driven his work onKoko, a tech nonprofit that grew out of...

India is home to about 60% of the world's wild Asian elephants, and around 80% of the animals' habitat lies outside protected areas, according to the Ministry of Environment, Forest, and Climate Change. That brings people and wildlife into close contact, and clashes can turn lethal: There have been some 3,000 human casualties in the...

Jos Benschop is climbing a ladder to get to the top of his newest machine. It's a bit of a schlep. The contraption is the size of a double-decker bus-more than 150 tons of gleaming precision-milled aluminum covered in thousands of snaking tubes, colored cables, and pressurized tanks. From the ground, it looks like a...

It's cold, it's very, very noisy, and-if I can be quite honest with you-I'm not feeling super relaxed. I'm currently around 300 meters, or 1,000 feet, beneath the North Sea, in a dark, dank cave. It smells weird. And I am increasingly aware of the pressure from millions of tons of seawater just above my...

There are plenty of useful things a metric can reveal. There are even more it can obscure or corrupt. It took me well over a decade of tracking my own life in ever greater detail to fully appreciate this duality, which probably reveals something about both me and the nature of measurement. Like a lot...

This week, I covered the story of Casey Harrell-a man with ALS who is the first power user" of a brain implant, according to the researchers who worked with him.

Solar geoengineering is often portrayed as a sort of emergency brake. Something along the lines of Pull in case of climate emergency to scatter light-reflecting particles to bounce sunlight out of the atmosphere and cool the planet. But it might be less like a simple brake and more like a complicated, entirely unsolved puzzle. Some...

Underneath an Apennine massif, below the Jinping Mountains of Sichuan, and at the bottom of a South Dakota mine, there is a cosmic hunt afoot. Isolated deep beneath these rocky shields, massive detectors filled with liquid xenon aim to make the first direct detections of dark matter, the long-sought invisible substance whose gravity has sculpted...

Most of Kenya's power grid runs on renewables. But with 25% of communities lacking centralized electricity, the nation is looking to off-grid solar to hit its goal of delivering universal electricity access by 2030 without driving up emissions. The ever-improving economics of solar technology have helped. A couple of years ago, a panel cost about...
