Learning to fly

March 16, 2022

Andrea Henshall, a retired major in the U.S. Air Force and current MIT PhD student, has completed seven tours of combat, two years of aerial circus performance, and three higher education degrees (so far). But throughout each step of her journey, all roads seemed to point to MIT. Currently working on her doctoral degree with an MIT master’s already in her toolkit, she is quick to attribute her academic success to MIT’s open educational resources. “I kept coming back...

Professor Emeritus Peter Griffith, a pioneer in...

March 15, 2022

Peter “Pete” Griffith ScD ’56, professor emeritus of mechanical engineering at MIT and a pioneer in heat transfer and fluid mechanics, passed away at age 94 on Saturday, March 5. Griffith was born on Sept. 23, 1927, in London but was raised in Huntington, Long Island. He spent a lot of his time in the woods and on the beach by his childhood home. Those closest to him knew that Griffith spent his time making forges and tinkering with...

When it comes to AI, can we...

March 15, 2022

Huge amounts of data are needed to train machine-learning models to perform image classification tasks, such as identifying damage in satellite photos following a natural disaster. However, these data are not always easy to come by. Datasets may cost millions of dollars to generate, if usable data exist in the first place, and even the best datasets often contain biases that negatively impact a model’s performance. To circumvent some of the problems presented by datasets, MIT researchers developed a...

Look! Up in the sky! Is it...

March 15, 2022

The first worlds beyond our solar system were discovered three decades ago. Since then, close to 5,000 exoplanets have been confirmed in our galaxy. Astronomers have detected another 5,000 planetary candidates — objects that might be planets but have yet to be confirmed. Now, the list of planets has shrunk by at least three. In a study appearing today in the Astronomical Journal, MIT astronomers report that three, and potentially four, planets that were originally discovered by NASA’s Kepler...

MIT Morningside Academy for Design created as...

March 14, 2022

MIT President L. Rafael Reif today announced the creation of the MIT Morningside Academy for Design, a major interdisciplinary center that will build on the Institute’s leadership in design-focused education and become a global hub for design research, thinking, and entrepreneurship. The new academy, which aims to foster collaboration and innovation on campus, will be housed in the School of Architecture and Planning. Projected to launch in September 2022, it will create and administer academic and research programs across...

An “oracle” for predicting the evolution of...

March 11, 2022

Despite the sheer number of genes that each human cell contains, these so-called “coding” DNA sequences comprise just 1 percent of our entire genome. The remaining 99 percent is made up of “non-coding” DNA — which, unlike coding DNA, does not carry the instructions to build proteins. One vital function of this non-coding DNA, also called “regulatory” DNA, is to help turn genes on and off, controlling how much (if any) of a protein is made. Over time, as...

How to clean solar panels without water

March 11, 2022

Solar power is expected to reach 10 percent of global power generation by the year 2030, and much of that is likely to be located in desert areas, where sunlight is abundant. But the accumulation of dust on solar panels or mirrors is already a significant issue — it can reduce the output of photovoltaic panels by as much as 30 percent in just one month — so regular cleaning is essential for such installations. But cleaning solar panels...

Computational modeling guides development of new materials

March 11, 2022

Metal-organic frameworks, a class of materials with porous molecular structures, have a variety of possible applications, such as capturing harmful gases and catalyzing chemical reactions. Made of metal atoms linked by organic molecules, they can be configured in hundreds of thousands of different ways. To help researchers sift through all of the possible metal-organic framework (MOF) structures and help identify the ones that would be most practical for a particular application, a team of MIT computational chemists has developed...

Historic entrepreneurship course shows no signs of...

March 11, 2022

In a process that has taken place for more than 60 years at MIT, this week a group of students gathered to practice entrepreneurship at a whirlwind pace designed to mimic the steep learning curve required to start a company. MIT’s course 15.390 (New Enterprises) has been held every year since 1961 — a time when entrepreneurship education was little more than an obscure idea. Indeed, many people believe New Enterprises is the oldest entrepreneurship course in the country,...

Yen-Jie Lee probes particle collision data for...

March 11, 2022

When Yen-Jie Lee came to MIT as a graduate student in 2006, it was a bit of a culture shock. The aspiring particle physicist had studied physics at National Taiwan University before his career took a hiatus in the forested mountains of Taiwan. There, he worked as a marine corps lieutenant to fulfill the nation’s required military service. He still remembers the deafening crackle of artillery drills and the unyielding pressure of daily military life. “That experience made me...

2022 MacVicar Faculty Fellows named

March 11, 2022

The Office of the Vice Chancellor and the Registrar’s Office have announced this year’s Margaret MacVicar Faculty Fellows: professor of mechanical engineering Kenneth Kamrin; professor of electrical engineering and computer science Jeffrey Lang; professor of earth, atmospheric and planetary sciences W. David McGee; and professor of chemistry Matthew Shoulders. For 30 years, the MIT provost has recognized exemplary and sustained contributions to undergraduate education at MIT. The MacVicar Faculty Fellows program was named after Margaret MacVicar, the first dean for undergraduate...

Study: Ice flow is more sensitive to...

March 10, 2022

The rate of glacier ice flow is more sensitive to stress than previously calculated, according to a new study by MIT researchers that upends a decades-old equation used to describe ice flow. Stress in this case refers to the forces acting on Antarctic glaciers, which are primarily influenced by gravity that drags the ice down toward lower elevations. Viscous glacier ice flows “really similarly to honey,” explains Joanna Millstein, a PhD student in the Glacier Dynamics and Remote Sensing...

Design course challenges students to solve real-world...

March 9, 2022

During this year’s Independent Activities Period, a group of 29 first- and second-year students immersed themselves in wildfire suppression and search-and-rescue missions. Not literally, of course; these projects were aircraft autonomy simulations, yet they couldn’t be more timely, given the growing incidence of natural disasters attributed to climate change. The two missions were at the core of this year’s Momentum program, a six-unit interdisciplinary design course facilitated by the Office of Minority Education (OME). The course, which has been...

Using soap to remove micropollutants from water

March 9, 2022

Imagine millions of soapy sponges the size of human cells that can clean water by soaking up contaminants. This simplistic model is used to describe technology that MIT chemical engineers have recently developed to remove micropollutants from water — a concerning, worldwide problem. Patrick S. Doyle, the Robert T. Haslam Professor of Chemical Engineering, PhD student Devashish Pratap Gokhale, and undergraduate Ian Chen recently published their research on micropollutant removal in the journal ACS Applied Polymer Materials. The work...

Using nature’s structures in wooden buildings

March 9, 2022

Concern about climate change has focused significant attention on the buildings sector, in particular on the extraction and processing of construction materials. The concrete and steel industries together are responsible for as much as 15 percent of global carbon dioxide emissions. In contrast, wood provides a natural form of carbon sequestration, so there’s a move to use timber instead. Indeed, some countries are calling for public buildings to be made at least partly from timber, and large-scale timber buildings...
