Everything is a Brand

Designing zeolites, porous materials made to trap...

August 24, 2022

Zeolites are a class of minerals used in everything from industrial catalysts and chemical filters to laundry detergents and cat litter. They are mostly composed of silicon and aluminum — two abundant, inexpensive elements — plus oxygen; they have a crystalline structure; and most significantly, they are porous. Among the regularly repeating atomic patterns in them are tiny interconnected openings, or pores, that can trap molecules that just fit inside them, allow smaller ones to pass through, or block...

Taking a magnifying glass to data center...

August 24, 2022

When the MIT Lincoln Laboratory Supercomputing Center (LLSC) unveiled its TX-GAIA supercomputer in 2019, it provided the MIT community a powerful new resource for applying artificial intelligence to their research. Anyone at MIT can submit a job to the system, which churns through trillions of operations per second to train models for diverse applications, such as spotting tumors in medical images, discovering new drugs, or modeling climate effects. But with this great power comes the great responsibility of managing and operating it in...

New leadership at MIT’s Center for Biomedical...

August 24, 2022

As it continues in its mission to improve global health through the development and implementation of biomedical innovation, the MIT Center for Biomedical Innovation (CBI) today announced changes to its leadership team: Stacy Springs has been named executive director, and Professor Richard Braatz has joined as the center’s new associate faculty director. The change in leadership comes at a time of rapid development in new therapeutic modalities, growing concern over global access to biologic medicines and healthy food, and...

MIT chemists develop a wireless electronic lateral...

August 24, 2022

Lateral flow assays (LFA) tests have become ubiquitous within the general public; they are the format for standard home pregnancy and Covid-19 tests, indicating a positive result with a colored line, and a negative result with no colored line. In their current iteration, these tests are largely qualitative and binary in their outputs. Various attempts to make a quantitative LFA have yielded complications due to the optical basis of a quantitative test — scattered stray light and faint images....

Building better batteries, faster

August 24, 2022

To help combat climate change, many car manufacturers are racing to add more electric vehicles in their lineups. But to convince prospective buyers, manufacturers need to improve how far these cars can go on a single charge. One of their main challenges? Figuring out how to make extremely powerful but lightweight batteries. Typically, however, it takes decades for scientists to thoroughly test new battery materials, says Pablo Leon, an MIT graduate student in materials science. To accelerate this process,...

Bridging careers in aerospace manufacturing and fusion...

August 23, 2022

“A big theme of my life has been focusing on intentional inclusion and how I can create environments where people can really bring their whole authentic selves to work,” says Joy Dunn ’08. As the head of operations at Commonwealth Fusion Systems, an MIT spinout working to achieve commercial fusion energy, Dunn looks for solutions to the world’s greatest climate challenges — while creating an open and equitable work environment where everyone can succeed. This theme has been cultivated...

Using seismology for groundwater management

August 22, 2022

As climate change increases the number of extreme weather events, such as megadroughts, groundwater management is key for sustaining water supply. But current groundwater monitoring tools are either costly or insufficient for deeper aquifers, limiting our ability to monitor and practice sustainable management in populated areas. Now, a new paper published in Nature Communications bridges seismology and hydrology with a pilot application that uses seismometers as a cost-effective way to monitor and map groundwater fluctuations. “Our measurements are independent...

John Tirman, political theorist and executive director...

August 22, 2022

John Tirman, an MIT scholar in political theory and expert on U.S.-Iran relations and human security, passed away on the morning of Aug. 19 after suffering cardiac arrest. He was 72. Since 2004, Tirman served as the executive director of and principal research scientist at the MIT Center for International Studies (CIS). During this time, he was a prolific and thoughtful — but always modest — leader of many of the center’s initiatives. He spearheaded several projects on U.S.-Iran relations, and...

Stranded assets could exact steep costs on...

August 19, 2022

A 2021 study in the journal Nature found that in order to avert the worst impacts of climate change, most of the world’s known fossil fuel reserves must remain untapped. According to the study, 90 percent of coal and nearly 60 percent of oil and natural gas must be kept in the ground in order to maintain a 50 percent chance that global warming will not exceed 1.5 degrees Celsius above preindustrial levels. As the world transitions away from...

When a task adds more steps, this...

August 18, 2022

Life is full of processes to learn and then relearn when they become more elaborate. One day you log in to an app with just a password, then the next day you also need a code texted to you. One day you can just pop your favorite microwavable lunch into the oven for six straight minutes, but then the packaging changes and you have to cook it for three minutes, stir, and then heat it for three more. Our...

Engineers fabricate a chip-free, wireless electronic “skin”

August 18, 2022

Wearable sensors are ubiquitous thanks to wireless technology that enables a person’s glucose concentrations, blood pressure, heart rate, and activity levels to be transmitted seamlessly from sensor to smartphone for further analysis. Most wireless sensors today communicate via embedded Bluetooth chips that are themselves powered by small batteries. But these conventional chips and power sources will likely be too bulky for next-generation sensors, which are taking on smaller, thinner, more flexible forms. Now MIT engineers have devised a new...

Helping older adults stay safe and independent

August 18, 2022

Smartwatches and Fitbits are great for tracking movement, but they weren’t designed for the type of people for whom collecting movement data is arguably most important: older adults who use mobility aids like walkers. For such adults, a change in activity could signal a life-threatening problem: Falls are a leading cause of injury-based death for older adults in the U.S. Decreased mobility could also signal problems like heart failure, depression, or cognitive decline. Now WalkWise is helping older adults...

MeepCon comes to MIT

August 17, 2022

Meep is not just the sound made by the Road Runner and Beaker the Muppet. Meep is a software package that MIT physicists originally developed in the early 2000s as a custom code written in C++ to facilitate the academic research of photonic crystals. It was released as open source in 2006. After nearly two decades of continuous development and growth, involving contributions from more than 40 developers, Meep is now widely used in the photonics community to research...

On the front lines of space innovation

August 17, 2022

George Lordos is not your typical graduate student. A degree in economics from Oxford University, an MBA from the MIT Sloan School of Management, and a 20-year professional career were not the end of his learning journey. His longtime passion for space, particularly the prospect of making a sustainable society on Mars a reality, drew him back to school yet again, this time to study aeronautics and astronautics at MIT. Lordos remembers vividly the impetus for this change in...

Wesley Harris elected vice president of National...

August 16, 2022

This spring, some members of the National Academy of Engineering (NAE) — a group representing the world’s most accomplished engineers — were tasked with electing the institution’s next vice president. MIT’s Wesley Harris emerged as their top choice. Officially announced as NAE’s new VP, Harris will help advance its mission to expand U.S. engineering frontiers while based on MIT’s campus. “It is a delight to see Wesley Harris celebrated for his substantial achievements as a researcher, educator, and mentor,...
