Puzzling out climate change
Shreyaa Raghavan’s journey into solving some of the world’s toughest challenges started with a simple love for puzzles. By high school, her knack for problem-solving naturally drew her to computer science. Through her participation in an entrepreneurship and leadership program, she built apps and twice made it to the semifinals of the program’s global competition. Her early successes made a computer science career seem like an obvious choice, but Raghavan says a significant competing interest left her torn. “Computer science...

Can deep learning transform heart failure prevention?
The ancient Greek philosopher and polymath Aristotle once concluded that the human heart is tri-chambered and that it was the single most important organ in the entire body, governing motion, sensation, and thought. Today, we know that the human heart actually has four chambers and that the brain largely controls motion, sensation, and thought. But Aristotle was correct in observing that the heart is a vital organ, pumping blood to the rest of the body to reach other vital...

Engineering joy
When the late professor emeritus Woodie Flowers SM ’68, MEng ’71, PhD ’73 was a student at MIT, most of his classes involved paper-and-pencil exercises with predetermined solutions. Flowers had an affinity for making things, and for making them work. When he transitioned from student to teacher, he chose to carry this approach into his method of instruction and, in doing so, he helped change the way engineering students are educated — at MIT, and around the world.  Flowers...

Creating a common language
A lot has changed in the 15 years since Kaiming He was a PhD student. “When you are in your PhD stage, there is a high wall between different disciplines and subjects, and there was even a high wall within computer science,” He says. “The guy sitting next to me could be doing things that I completely couldn’t understand.” In the seven months since he joined the MIT Schwarzman College of Computing as the Douglas Ross (1954) Career Development...

Validation technique could help scientists make more...
Should you grab your umbrella before you walk out the door? Checking the weather forecast beforehand will only be helpful if that forecast is accurate. Spatial prediction problems, like weather forecasting or air pollution estimation, involve predicting the value of a variable in a new location based on known values at other locations. Scientists typically use tried-and-true validation methods to determine how much to trust these predictions. But MIT researchers have shown that these popular validation methods can fail...

MIT method enables ultrafast protein labeling of...
A new technology developed at MIT enables scientists to label proteins across millions of individual cells in fully intact 3D tissues with unprecedented speed, uniformity, and versatility. Using the technology, the team was able to richly label large tissue samples in a single day. In their new study in Nature Biotechnology, they also demonstrate that the ability to label proteins with antibodies at the single-cell level across large tissue samples can reveal insights left hidden by other widely used...

Streamlining data collection for improved salmon population...
Sara Beery came to MIT as an assistant professor in MIT’s Department of Electrical Engineering and Computer Science (EECS) eager to focus on ecological challenges. She has fashioned her research career around the opportunity to apply her expertise in computer vision, machine learning, and data science to tackle real-world issues in conservation and sustainability. Beery was drawn to the Institute’s commitment to “computing for the planet,” and set out to bring her methods to global-scale environmental and biodiversity monitoring....

3 Questions: What the laws of physics...
Human activities continue to pump billions of tons of carbon dioxide into the atmosphere each year, raising global temperatures and driving extreme weather events. As countries grapple with climate impacts and ways to significantly reduce carbon emissions, there have been various efforts to advance carbon dioxide removal (CDR) technologies that directly remove carbon dioxide from the air and sequester it for long periods of time. Unlike carbon capture and storage technologies, which are designed to remove carbon dioxide at...

David McGee named head of the Department...
David McGee, the William R. Kenan Jr. Professor of Earth and Planetary Sciences at MIT, was recently appointed head of the MIT Department of Earth, Atmospheric and Planetary Sciences (EAPS), effective Jan. 15. He assumes the role from Professor Robert van der Hilst, the Schlumberger Professor of Earth and Planetary Sciences, who led the department for 13 years. McGee specializes in applying isotope geochemistry and geochronology to reconstruct Earth’s climate history, helping to ground-truth our understanding of how the...

Study in India shows kids use different...
In India, many kids who work in retail markets have good math skills: They can quickly perform a range of calculations to complete transactions. But as a new study shows, these kids often perform much worse on the same kinds of problems as they are taught in the classroom. This happens even though many of these students still attend school or attended school through 7th or 8th grades. Conversely, the study also finds, Indian students who are still enrolled...

Timeless virtues, new technologies
As the story goes, the Scottish inventor James Watt envisioned how steam engines should work on one day in 1765, when he was walking across Glasgow Green, a park in his hometown. Watt realized that putting a separate condenser in an engine would allow its main cylinder to remain hot, making the engine more efficient and compact than the huge steam engines then in existence. And yet Watt, who had been pondering the problem for a while, needed a...

Driving innovation, from Silicon Valley to Detroit
Across a career’s worth of pioneering product designs, Doug Field’s work has shaped the experience of anyone who’s ever used a MacBook Air, ridden a Segway, or driven a Tesla Model 3. But his newest project is his most ambitious yet: reinventing the Ford automobile, one of the past century’s most iconic pieces of technology. As Ford’s chief electric vehicle (EV), digital, and design officer, Field is tasked with leading the development of the company’s electric vehicles, while making...

How telecommunications cables can image the ground...
When people think about fiber optic cables, its usually about how they’re used for telecommunications and accessing the internet. But fiber optic cables — strands of glass or plastic that allow for the transmission of light — can be used for another purpose: imaging the ground beneath our feet. MIT Department of Earth, Atmospheric and Planetary Sciences (EAPS) PhD student Hilary Chang recently used the MIT fiber optic cable network to successfully image the ground underneath campus using a...
