Everything is a Brand

MIT engineers develop a fully 3D-printed electrospray...

February 12, 2025

An electrospray engine applies an electric field to a conductive liquid, generating a high-speed jet of tiny droplets that can propel a spacecraft. These miniature engines are ideal for small satellites called CubeSats that are often used in academic research. Since electrospray engines utilize propellant more efficiently than the powerful, chemical rockets used on the launchpad, they are better suited for precise, in-orbit maneuvers. The thrust generated by an electrospray emitter is tiny, so electrospray engines typically use an...

Gift from Sebastian Man ’79, SM ’80...

February 11, 2025

The MIT Stephen A. Schwarzman College of Computing has received substantial support for its striking new headquarters on Vassar Street in Cambridge, Massachusetts. A major gift from Sebastian Man ’79, SM ’80 will be recognized with the naming of a key space in the building, enriching the academic and research activities of the MIT Schwarzman College of Computing and MIT. Man, the first major donor to support the building since Stephen A. Schwarzman’s foundational gift established the Schwarzman College...

Bridging philosophy and AI to explore computing...

February 11, 2025

During a meeting of class 6.C40/24.C40 (Ethics of Computing), Professor Armando Solar-Lezama poses the same impossible question to his students that he often asks himself in the research he leads with the Computer Assisted Programming Group at MIT: “How do we make sure that a machine does what we want, and only what we want?” At this moment, what some consider the golden age of generative AI, this may seem like an urgent new question. But Solar-Lezama, the Distinguished Professor...

To keep hardware safe, cut out the...

February 11, 2025

Imagine you’re a chef with a highly sought-after recipe. You write your top-secret instructions in a journal to ensure you remember them, but its location within the book is evident from the folds and tears on the edges of that often-referenced page. Much like recipes in a cookbook, the instructions to execute programs are stored in specific locations within a computer’s physical memory. The standard security method — referred to as “address space layout randomization” (ASLR) — scatters this...

Creating smart buildings with privacy-first sensors

February 11, 2025

Gaining a better understanding of how people move through the spaces where they live and work could make those spaces safer and more sustainable. But no one wants cameras watching them 24/7. Two former Media Lab researchers think they have a solution. Their company, Butlr, offers places like skilled nursing facilities, offices, and senior living communities a way to understand how people are using buildings without compromising privacy. Butlr uses low-resolution thermal sensors and an analytics platform to help...

Puzzling out climate change

February 10, 2025

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?

February 10, 2025

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

February 9, 2025

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

February 7, 2025

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...

February 7, 2025

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...

February 6, 2025

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...

February 6, 2025

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...

February 6, 2025

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...

February 5, 2025

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...

February 5, 2025

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...
