Tools for making imagination blossom at MIT.nano

September 9, 2024

The MIT community and visitors have a new reason to drop by MIT.nano: six artworks by Brazilian artist and sculptor Denise Milan. Located in the open-air stairway connecting the first- and second-floor galleries within the nanoscience and engineering facility, the works center around the stone as a microcosm of nature. From Milan’s “Mist of the Earth” series, evocative of mandalas, the project asks viewers to reflect on the environmental changes that result from human-made development. Milan is the inaugural...

A fast and flexible approach to help...

September 9, 2024

To the untrained eye, a medical image like an MRI or X-ray appears to be a murky collection of black-and-white blobs. It can be a struggle to decipher where one structure (like a tumor) ends and another begins. When trained to understand the boundaries of biological structures, AI systems can segment (or delineate) regions of interest that doctors and biomedical workers want to monitor for diseases and other abnormalities. Instead of losing precious time tracing anatomy by hand across...

No detail too small

September 6, 2024

Sarah Sterling, director of the Cryo-Electron Microscopy, or Cryo-EM, core facility, often compares her job to running a small business. Each day brings a unique set of jobs ranging from administrative duties and managing facility users to balancing budgets and maintaining equipment. Although one could easily be overwhelmed by the seemingly never-ending to-do list, Sterling finds a great deal of joy in wearing so many different hats. One of her most essential tasks involves clear communication with users when the...

New filtration material could remove long-lasting chemicals...

September 6, 2024

Water contamination by the chemicals used in today’s technology is a rapidly growing problem globally. A recent study by the U.S. Centers for Disease Control found that 98 percent of people tested had detectable levels of PFAS, a family of particularly long-lasting compounds also known as “forever chemicals,” in their bloodstream. A new filtration material developed by researchers at MIT might provide a nature-based solution to this stubborn contamination issue. The material, based on natural silk and cellulose, can remove...

September 4, 2024

Sam Madden, the College of Computing Distinguished Professor of Computing at MIT, has been named the new faculty head of computer science in the MIT Department of Electrical Engineering and Computer Science (EECS), effective Aug. 1. Madden succeeds Arvind, a longtime MIT professor and prolific computer scientist, who passed away in June. “Sam’s research leadership and commitment to excellence, along with his thoughtful and supportive approach, makes him a natural fit to help lead the department going forward. In...

Remembering Mathieu Le Provost: AeroAstro researcher, adventurer,...

September 4, 2024

Mathieu Le Provost, a postdoc in the Department of Aeronautics and Astronautics, passed away unexpectedly on July 30 while traveling in France. Le Provost joined AeroAstro in 2023 and was a member of the Uncertainty Quantification Group, led by Professor Youssef Marzouk. Marzouk and Le Provost connected in 2020 when Le Provost reached out over email, eager to explore potential research collaborations. Although the Covid-19 pandemic prevented them from meeting in person, Marzouk, le Provost, and colleagues Ricardo Baptista...

Nanostructures enable on-chip lightwave-electronic frequency mixer

September 4, 2024

Imagine how a phone call works: Your voice is converted into electronic signals, shifted up to higher frequencies, transmitted over long distances, and then shifted back down so it can be heard clearly on the other end. The process enabling this shifting of signal frequencies is called frequency mixing, and it is essential for communication technologies like radio and Wi-Fi. Frequency mixers are vital components in many electronic devices and typically operate using frequencies that oscillate billions (GHz, gigahertz)...

3 Questions: Evidence for planetary formation through...

September 4, 2024

Exoplanets form in protoplanetary disks, a collection of space dust and gas orbiting a star. The leading theory of planetary formation, called core accretion, occurs when grains of dust in the disk collect and grow to form a planetary core, like a snowball rolling downhill. Once it has a strong enough gravitational pull, other material collapses around it to form the atmosphere. A secondary theory of planetary formation is gravitational collapse. In this scenario, the disk itself becomes gravitationally...

Enabled by a significant gift, MIT’s Security...

September 4, 2024

MIT’s Security Studies Program has received a $45 million gift from The Stanton Foundation to expand its leading work on the vital issue of global nuclear security. The support will allow the program to create a new center on the topic while extending and enhancing research, teaching, and policy outreach in an area where the Institute is a longstanding leader with wide-ranging faculty expertise. “We are on the cusp of a new and more dangerous nuclear age, with the modernization...

Study: EV charging stations boost spending at...

September 4, 2024

Charging stations for electric vehicles are essential for cleaning up the transportation sector. A new study by MIT researchers suggests they’re good for business, too. The study found that, in California, opening a charging station boosted annual spending at each nearby business by an average of about $1,500 in 2019 and about $400 between January 2021 and June 2023. The spending bump amounts to thousands of extra dollars annually for nearby businesses, with the increase particularly pronounced for businesses...

MIT team wins grand prize at NASA’s...

September 3, 2024

The members of the MIT First Nations Launch team had never built a drone before when they faced the 2024 NASA First Nations Launch High-Power Rocket Competition. This year’s challenge invited teams to design, build, and launch a high-power rocket carrying a scientific payload that deploys mid-air and safely returns to the ground, integrating Indigenous methodologies. The eight-student team of all Indigenous students earned the compatition’s grand prize, as well as first place in the written portion. Deploying a...

Nurturing success

September 3, 2024

The start and finish of a degree program are pivotal moments in the lives of MIT’s graduate students. In her first three years in MIT’s Department of Political Science, professor Mariya Grinberg’s mentorship has helped numerous students start their graduate journeys with confidence and direction. Nuh Gedik, who joined the Department of Physics in 2008, looks to the finish line: he finds joy in seeing his students reach personal and professional success at the end of their PhDs. Both...

For developing designers, there’s magic in 2.737...

September 3, 2024

The field of mechatronics is multidisciplinary and interdisciplinary, occupying the intersection of mechanical systems, electronics, controls, and computer science. Mechatronics engineers work in a variety of industries — from space exploration to semiconductor manufacturing to product design — and specialize in the integrated design and development of intelligent systems. For students wanting to learn mechatronics, it might come as a surprise that one of the most powerful teaching tools available for the subject matter is simply a pen and...

How MIT’s online resources provide a “highly...

August 29, 2024

Charalampos (Haris) Sampalis was well established in his career as a product manager at a telecommunications company in Greece. Yet, as someone who enjoys learning, he was on a mission to acquire more knowledge and develop new skills. That’s how he discovered MIT Open Learning resources. With a bachelor’s degree in computer science from the University of Crete and a master’s in innovation management and entrepreneurship from Hellenic Open University — the only online/distance learning university in Greece — Sampalis...

Designing better delivery for medical therapies

August 28, 2024

Early in his undergraduate studies in bioengineering, Sayo Eweje was thinking of a career in medicine. He was inspired by the idea of harnessing medical knowledge to improve patients’ lives, having grown up seeing his father do so as a gastroenterologist. However, his research experiences in college made him appreciate how scientific advancement can lead to paradigm-shifting innovations. What if he could contribute to breakthroughs that improved lives on a much larger scale? “That idea really captured me, and...
