Searching for multiplicity, in computer science and...

August 15, 2021

Right now, Rodrigo Ochigame is reading Russian science fiction, Yugoslav art history, Indian philosophy, and Afro-Caribbean political theory. They are listening to Belgian electroacoustic music, Mongolian experimental rock, and Ethiopian jazz. Occasionally, the PhD student in the Program in History, Anthropology, and Science, Technology, and Society (HASTS) even throws dice to select a new MBTA stop to explore. More often, they apply this practice on the MIT campus, randomly attending departmental seminars on topics ranging from astrophysics to macroeconomics...

Professor Emeritus Lawrence Frishkopf, expert in communications...

August 13, 2021

Lawrence Frishkopf, MIT professor emeritus of electrical engineering and computer science, died on June 25, one day before his 91st birthday. An area chair in the department, Frishkopf was aﬃliated with both the Communications Biophysics group in the Research Laboratory of Electronics and the Harvard-MIT Program in Health Sciences and Technology, where his research focused on the biophysics of auditory systems. Born in Philadelphia in 1930, he developed an interest in science as a young child, telling his Polish...

3 Questions: Making the 2021-22 school year...

August 13, 2021

What’s the best way to get K-12 students across the U.S. to bounce back from the pandemic? MIT’s Justin Reich has an idea: Ask them. Reich, an associate professor in MIT’s program in Comparative Media Studies/Writing and director of the MIT Teaching Systems Lab, has co-authored a new report on the return to the classroom in the 2021-22 school year, based on interviews with over 250 educators and 4,000 students, in addition to 10 charrettes involving students, teachers, parents,...

Study provides suggestions for keeping classroom air...

August 13, 2021

Open windows and a good heating, ventilation, and air conditioning (HVAC) system are starting points for keeping classrooms safe during the Covid-19 pandemic. But they are not the last word, according to a new study from researchers at MIT. The study shows how specific classroom configurations may affect air quality and necessitate additional measures, beyond HVAC use or open windows, to reduce the spread of aerosols — those tiny, potentially Covid-carrying particles that can stay suspended in the air...

Why boiling droplets can race across hot...

August 12, 2021

When you’re frying something in a skillet and some droplets of water fall into the pan, you may have noticed those droplets skittering around on top of the film of hot oil. Now, that seemingly trivial phenomenon has been analyzed and understood for the first time by researchers at MIT — and may have important implications for microfluidic devices, heat transfer systems, and other useful functions. A droplet of boiling water on a hot surface will sometimes levitate on...

MIT Solar Electric Vehicle Team wins 2021...

August 12, 2021

After three years of hard work, the MIT Solar Electric Vehicle Team took first place at the 2021 American Solar Challenge (ASC) on August 7 in the Single Occupancy Vehicle (SOV) category. During the five-day race, their solar car, Nimbus — designed and built entirely by students — beat eight other SOVs from schools across the country, traversing 1,109 miles and maintaining an average speed of 38.4 miles per hour. Held every two years, the ASC has traditionally been...

August 11, 2021

Professors Daniel Hastings and Maria Yang have been named associate deans of MIT’s School of Engineering. Their new roles took effect August 1. Hastings is the Cecil and Ida Green Education Professor of Aeronautics and Astronautics, and head of the Department of Aeronautics and Astronautics, a role which he will continue in addition to his associate dean appointment. He will focus on advancing diversity, equity, and inclusion initiatives across the school and in collaboration with Nandi Bynoe, the School of Engineering’s Assistant Dean for Diversity,...

Global warming begets more warming, new paleoclimate...

August 11, 2021

It is increasingly clear that the prolonged drought conditions, record-breaking heat, sustained wildfires, and frequent, more extreme storms experienced in recent years are a direct result of rising global temperatures brought on by humans’ addition of carbon dioxide to the atmosphere. And a new MIT study on extreme climate events in Earth’s ancient history suggests that today’s planet may become more volatile as it continues to warm. The study, appearing today in Science Advances, examines the paleoclimate record of...

Mehrdad Jazayeri wants to know how our...

August 11, 2021

Much of our daily life requires us to make inferences about the world around us. As you think about which direction your tennis opponent will hit the ball, or try to figure out why your child is crying, your brain is searching for answers about possibilities that are not directly accessible through sensory experiences. MIT Associate Professor Mehrdad Jazayeri has devoted most of his career to exploring how the brain creates internal representations, or models, of the external world...

Electrifying cars and light trucks to meet...

August 10, 2021

On Aug. 5, the White House announced that it seeks to ensure that 50 percent of all new passenger vehicles sold in the United States by 2030 are powered by electricity. The purpose of this target is to enable the U.S to remain competitive with China in the growing electric vehicle (EV) market and meet its international climate commitments. Setting ambitious EV sales targets and transitioning to zero-carbon power sources in the United States and other nations could lead to...

Considering the spiderweb

August 10, 2021

The spiderweb is an everyday architecture — non-monumental and easily overlooked. Yet artists and scientists are working to unlock the secret of its complex geometry, a mystery that could inspire everything from resilient new building materials to deeper understandings of the structure of the universe. When artist Tomàs Saraceno first came to MIT in 2012, as the inaugural Center for Art, Science, & Technology (CAST) visiting artist, he had recently pioneered a new method of scanning 3D webs with...

Machine learning discovers new sequences to boost...

August 10, 2021

Duchenne muscular dystrophy (DMD), a rare genetic disease usually diagnosed in young boys, gradually weakens muscles across the body until the heart or lungs fail. Symptoms often show up by age 5; as the disease progresses, patients lose the ability to walk around age 12. Today, the average life expectancy for DMD patients hovers around 26. It was big news, then, when Cambridge, Massachusetts-based Sarepta Therapeutics announced in 2019 a breakthrough drug that directly targets the mutated gene responsible...

System trains drones to fly around obstacles...

August 10, 2021

If you follow autonomous drone racing, you likely remember the crashes as much as the wins. In drone racing, teams compete to see which vehicle is better trained to fly fastest through an obstacle course. But the faster drones fly, the more unstable they become, and at high speeds their aerodynamics can be too complicated to predict. Crashes, therefore, are a common and often spectacular occurrence. But if they can be pushed to be faster and more nimble, drones...

Biological engineers find a new target for...

August 10, 2021

Every year, more than 200 million people are infected with malaria, and nearly 500,000 die from the disease. Existing drugs can treat the infection, but the parasite that causes the disease has evolved resistance to many of them. To help overcome that resistance, scientists are now searching for drugs that hit novel molecular targets within the Plasmodium falciparum parasite that causes malaria. An international team that includes MIT researchers has identified a potential new target: the acetyl-CoA synthetase, an...

Exact symbolic artificial intelligence for faster, better...

August 9, 2021

The justice system, banks, and private companies use algorithms to make decisions that have profound impacts on people’s lives. Unfortunately, those algorithms are sometimes biased — disproportionately impacting people of color as well as individuals in lower income classes when they apply for loans or jobs, or even when courts decide what bail should be set while a person awaits trial. MIT researchers have developed a new artificial intelligence programming language that can assess the fairness of algorithms more...
