Technique could enable cheaper fertilizer production

May 4, 2020

Most of the world’s fertilizer is produced in large manufacturing plants, which require huge amounts of energy to generate the high temperatures and pressures needed to combine nitrogen and hydrogen into ammonia. MIT chemical engineers are working to develop a smaller-scale alternative, which they envision could be used to locally produce fertilizer for farmers in remote, rural areas, such as sub-Saharan Africa. Fertilizer is often hard to obtain in such areas because of the cost of transporting it from...

Myth-busting on YouTube

May 3, 2020

In mid-March, Izabella Pena received a WhatsApp text from a friend in Indianapolis, Indiana. “He said, ‘Oh, I got your audio message from a priest in rural São Paulo,’” remembers Pena, a postdoc in Department of Biology Professor David Sabatini’s lab at the Whitehead Institute for Biomedical Research. Pena had recorded the five-minute audio message about risk groups and the novel coronavirus SARS-CoV-2 for her family’s text thread after she heard one-too-many comments about how only the elderly caught the...

Three from MIT elected to the National...

May 1, 2020

On April 27, the National Academy of Sciences elected 120 new members and 26 international associates, including three professors from MIT — Abhijit Banerjee, Bonnie Berger, and Roger Summons — recognizing their “distinguished and continuing achievements in original research.” Current membership totals 2,403 active members and 501 international associates, including 190 Nobel Prize recipients. The National Academy of Sciences is a private, nonprofit institution for scientific advancement established in 1863 by congressional charter and signed into law by President Abraham...

MIT IDEAS celebrates social innovation at the...

May 1, 2020

Members of the MIT community from around the world gathered virtually on Sunday, April 26 to celebrate the 19th annual IDEAS Awards presented by the PKG Center for Public Service. IDEAS is MIT’s social innovation challenge and has been bringing MIT students together with mentors from industry, academia, and community organizations for nearly 20 years to tackle pressing social and environmental issues through innovation. Due to the outbreak of Covid-19, the IDEAS Showcase (which typically takes place in-person at...

Professor Wayne O’Neil, linguist and advocate for...

May 1, 2020

MIT professor of linguistics Wayne O’Neil died on March 22 at his home in Somerville, Massachusetts. The cause of death was cancer. He was 88 years old. O’Neil’s work focused on syntactic and phonological theory, on the role of linguistics in the school curriculum, and on second-language acquisition, both the theory and the relevance of the latter to bilingual education and to the revitalization of indigenous languages. An MIT faculty member for more than 50 years, O’Neil served as...

Weekly calls keep students connected to the...

May 1, 2020

When the MIT campus is alive, it nearly sings with innovation and excitement. Students sustain one another with activities ranging from building in makerspaces to psetting in residence halls to pick-up soccer games on the fields. But how can they remain connected during a pandemic, where physical distancing is the new normal? What can replace the informal chats with faculty members after class? Throw in remote learning — and the Infinite Corridor seems infinitely far away. Enter the MIT...

A foolproof way to shrink deep learning...

April 30, 2020

As more artificial intelligence applications move to smartphones, deep learning models are getting smaller to allow apps to run faster and save battery power. Now, MIT researchers have a new and better way to compress models. It’s so simple that they unveiled it in a tweet last month: Train the model, prune its weakest connections, retrain the model at its fast, early training rate, and repeat, until the model is as tiny as you want. “That’s it,” says Alex Renda, a PhD...

The MIT Press offers e-resources during the...

April 9, 2020

To address the increased need for digital content and distance learning during the Covid-19 pandemic, the MIT Press is rapidly expanding access to a variety of free content. From making select books freely available on their open-source platform to granting libraries complimentary access to its institutional e-book platform, the press will continue to bring content to readers in a variety of formats. “The full staff is now working remotely and will continue to do so for as long as...

Katie Collins, Vaishnavi Phadnis, and Vaibhavi Shah...

April 9, 2020

MIT students Katie Collins, Vaishnavi Phadnis, and Vaibhavi Shah have been selected to receive a Barry Goldwater Scholarship for the 2020-21 academic year. Over 5,000 college students from across the United States were nominated for the scholarships, from which only 396 recipients were selected based on academic merit. The Goldwater scholarships have been conferred since 1989 by the Barry Goldwater Scholarship and Excellence in Education Foundation. These scholarships have supported undergraduates who go on to become leading scientists, engineers,...

In virtual town hall, MIT leadership updates...

April 9, 2020

As the MIT community adjusts to this unique period of separation and disruption, the Institute’s top leaders held an online “town hall” on Tuesday to answer some of the most frequent questions being asked by students, faculty, and staff. Roughly 7,000 members of the MIT community tuned in live for an update on adjustments and activities underway now, and on planning for the coming summer and fall, given the uncertainties as to how the Covid-19 pandemic may unfold. “These...

Bluetooth signals from your smartphone could automate...

April 9, 2020

Imagine you’ve been diagnosed as Covid-19 positive. Health officials begin contact tracing to contain infections, asking you to identify people with whom you’ve been in close contact. The obvious people come to mind — your family, your coworkers. But what about the woman ahead of you in line last week at the pharmacy, or the man bagging your groceries? Or any of the other strangers you may have come close to in the past 14 days? A team led...

Sprayable user interfaces

April 8, 2020

For decades researchers have envisioned a world where digital user interfaces are seamlessly integrated with the physical environment, until the two are virtually indistinguishable from one another. This vision, though, is held up by a few boundaries. First, it’s difficult to integrate sensors and display elements into our tangible world due to various design constraints. Second, most methods to do so are limited to smaller scales, bound by the size of the fabricating device. Recently, a group of researchers...

Titan’s missing river deltas and an Earthly...

April 8, 2020

“I’ll never forget the moment when I first saw new Cassini data come down from Titan’s surface,” says Samuel Birch. “I was in awe at witnessing this brand new, never-seen-before bit of our solar system.” Birch explores and models the evolution of the surfaces of planets, moons, and small bodies in the outer solar system, including Saturn’s largest moon, Titan, and the Comet 67P/Churyumov-Gerasimenko — two very different, icy worlds investigated by the spacecraft Cassini and Rosetta. He joins...

Learning about artificial intelligence: A hub of...

April 7, 2020

In light of the recent events surrounding Covid-19, learning for grades K-12 looks very different than it did a month ago. Parents and educators may be feeling overwhelmed about turning their homes into classrooms. With that in mind, a team led by Media Lab Associate Professor Cynthia Breazeal has launched aieducation.mit.edu to share a variety of online activities for K-12 students to learn about artificial intelligence, with a focus on how to design and use it responsibly. Learning resources provided...

Computational thinking class enables students to engage...

April 7, 2020

When an introductory computational science class, which is open to the general public, was repurposed to study the Covid-19 pandemic this spring, the instructors saw student registration rise from 20 students to nearly 300. Introduction to Computational Thinking (6.S083/18.S190), which applies data science, artificial intelligence, and mathematical models using the Julia programming language developed at MIT, was introduced in the fall as a pilot half-semester class. It was launched as part of the MIT Stephen A. Schwarzman College of...
