3 Questions: Seychelle Vos on detangling DNA

May 28, 2020

Seychelle Vos arrived in September 2019 as the Department of Biology’s newest assistant professor. Her lab in Building 68 uses cryogenic electron microscopy (cryo-EM), X-ray crystallography, biochemistry, and genetics to study how DNA and its associated proteins are organized inside the cell. Vos received her PhD from the University of California at Berkeley and completed her postdoctoral research at the Max Planck Institute for Biophysical Chemistry in Germany. She sat down to discuss her structural biology research, and why...

New technology enables fast protein synthesis

May 28, 2020

Many proteins are useful as drugs for disorders such as diabetes, cancer, and arthritis. Synthesizing artificial versions of these proteins is a time-consuming process that requires genetically engineering microbes or other cells to produce the desired protein. MIT chemists have devised a protocol to dramatically reduce the amount of time required to generate synthetic proteins. Their tabletop automated flow synthesis machine can string together hundreds of amino acids, the building blocks of proteins, within hours. The researchers believe their...

Algorithm quickly simulates a roll of loaded...

May 28, 2020

The fast and efficient generation of random numbers has long been an important challenge. For centuries, games of chance have relied on the roll of a die, the flip of a coin, or the shuffling of cards to bring some randomness into the proceedings. In the second half of the 20th century, computers started taking over that role, for applications in cryptography, statistics, and artificial intelligence, as well as for various simulations — climatic, epidemiological, financial, and so forth....

Media Advisory — MIT Online Commencement Friday,...

May 28, 2020

Members of the MIT community will come together from around the world to celebrate the Class of 2020 during an online ceremony on Friday, May 29 at 1:00 p.m. EDT. This year’s guest speaker will be Admiral William H. McRaven, a retired U.S. Navy four-star admiral and the former chancellor of the University of Texas system. The program will also feature a charge to the graduates by MIT President L. Rafael Reif, salutes from student leaders, a community-sourced musical...

Making nuclear energy cost-competitive

May 27, 2020

Nuclear energy is a low-carbon energy source that is vital to decreasing carbon emissions. A critical factor in its continued viability as a future energy source is finding novel and innovative ways to improve operations and maintenance (O&M) costs in the next generation of advanced reactors. The U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) established the Generating Electricity Managed by Intelligent Nuclear Assets (GEMINA) program to do exactly this. Through $27 million in funding, GEMINA is accelerating...

Solve at MIT builds partnerships to tackle...

May 27, 2020

In response to the Covid-19 pandemic, MIT Solve, a marketplace for social impact innovation, transformed its annual flagship event, Solve at MIT, into an interactive virtual gathering to convene the Solve and MIT communities. On May 12, nearly 800 people tuned in from all around the world to take part in Virtual Solve at MIT. The event connected innovators and social impact leaders through breakout sessions to discuss Solve’s Global Challenges and other timely topics, brain trusts to advise...

Lincoln Laboratory decommissions Lincoln Experimental Satellite–9

May 27, 2020

The longest continuously operating communications satellite in U.S. history, Lincoln Experimental Satellite–9 (LES-9), was decommissioned by MIT Lincoln Laboratory on May 20. The LES research team has been monitoring the satellite since it was launched in 1976. The gradual reduction in available power, coupled with the loss of the primary S-band telemetry data in early 2020, led to the decision to retire the satellite. “The Lincoln Experimental Satellite program was a monumental technical achievement and created the architectural framework...

Podcast transcript: A tale of two classes...

May 27, 2020

Like this year’s seniors, the Class of 1970 had its final semester disrupted: Fifty years ago, growing unrest over the Vietnam War led to the cancellation of MIT classes. In the podcast and transcript below, Karen Arenson ’70 and senior Bahrudin Trbalic share their experiences. Karen A.: My classmates and I do feel a connection to the Class of 2020 and empathize with the way their final semester has been up-ended. Narrator: When Class of 1970 president, Karen Arenson,...

Physicists measure a short-lived radioactive molecule for...

May 27, 2020

Researchers at MIT and elsewhere have combined the power of a super collider with techniques of laser spectroscopy to precisely measure a short-lived radioactive molecule, radium monofluoride, for the first time. Precision studies of radioactive molecules open up possibilities for scientists to search for new physics beyond the Standard Model, such as phenomena that violate certain fundamental symmetries in nature, and to look for signs of dark matter. The team’s experimental technique could also be used to perform laboratory...

How often do vaccine trials hit paydirt?

May 27, 2020

Vaccines are more likely to get through clinical trials than any other type of drug — but have been given relatively little pharmaceutical industry support during the last two decades, according to a new study by MIT scholars. Over a two-decade span from January 2000 to January 2020, private-sector vaccine-development efforts succeeded in bringing a drug to market 39.6 percent of the time, the researchers found. By contrast, programs to develop anti-infective therapeutics — medicines that lessen the severity...

Hacking Commencement

May 26, 2020

In the finest MIT tradition of community-driven innovation, the Commencement Committee and a core group of engineers, technologists, and artists across campus are putting minds and hands to work to create a meaningful, engaging online Commencement experience for the Class of 2020. Moving the tradition-rich celebration online without diminishing its significance, and with less than two months to plan, is a complex problem. The organizing team knew from the outset that the challenge would be to achieve the key...

Meet the MIT bilinguals: Dual materials science...

May 26, 2020

In high school, Talia Khan was passionate about musical theater. So, she was thrilled when she got to go to New York and see one of her idols, Audra McDonald, perform on Broadway in “Lady Day at Emerson’s Bar and Grill.” She waited at the stage door to meet her after the show, and she told McDonald how much she hoped to be a successful singer, too. As Khan recounts the conversation, McDonald said, “I won’t tell you not...

Undergraduates develop next-generation intelligence tools

May 26, 2020

The coronavirus pandemic has driven us apart physically while reminding us of the power of technology to connect. When MIT shut its doors in March, much of campus moved online, to virtual classes, labs, and chatrooms. Among those making the pivot were students engaged in independent research under MIT’s Undergraduate Research Opportunities Program (UROP). With regular check-ins with their advisors via Slack and Zoom, many students succeeded in pushing through to the end. One even carried on his experiments...

Search-and-rescue algorithm identifies hidden “traps” in ocean...

May 26, 2020

The ocean is a messy and turbulent space, where winds and weather kick up waves in all directions. When an object or person goes missing at sea, the complex, constantly changing conditions of the ocean can confound and delay critical search-and-rescue operations. Now researchers at MIT, the Swiss Federal Institute of Technology (ETH), the Woods Hole Oceanographic Institution (WHOI), and Virginia Tech have developed a technique that they hope will help first responders quickly zero in on regions of...

A Ticketmaster for science seminars

May 26, 2020

One of the perks of an academic’s pre-pandemic life was the chance, at least once a week, to take a break from problem sets and proofs, and walk down the hall or across campus to sit in on cutting-edge research presented by invited experts from around the world. Offered through a department’s regular seminar series, these talks were also opportunities to get some friendly face-to-face with colleagues who were otherwise buried in their own work. And on occasion, a...
