Letter from President Reif: Caring for each...
The following letter was sent to the MIT community today by President L. Rafael Reif. To the members of the MIT community, On Monday, the trial of Derek Chauvin will move to closing arguments, amid continued anguish across the country over systemic racism and violence against people of color.  I write now to acknowledge the pain, frustration, exhaustion and profound weight of this moment, to recognize the impact across our community, especially for people of color, and to offer...

3 Questions: Deborah Liverman on helping students...
MIT Career Advising and Professional Development (CAPD) has a simple mission statement: engaging undergraduates, graduate students, alumni, and postdocs in self-discovery to craft lives that are intellectually challenging, personally enriching, and of service to the world. With increased career uncertainty due to the pandemic, Deborah Liverman, executive director for CAPD, shares how the office can help students navigate a path to fulfilling work. Q: How is CAPD supporting students now that recruitment for employment and graduate school is virtual? ...

MIT juniors Yu Jing Chen and Max...
MIT students Yu Jing Chen and Max Williamson have been selected as 2021 Truman Scholars. Truman Scholars demonstrate outstanding leadership potential, a commitment to a career in government or the nonprofit sector, and academic excellence. Chen and Williamson join 62 other scholars who were selected from 845 candidates. MIT President L. Rafael Reif personally informed both students that they were selected for this competitive scholarship, telling them, “This year it was so competitive and this is so important,...

Toward deep-learning models that can reason about...
Whatever business a company may be in, software plays an increasingly vital role, from managing inventory to interfacing with customers. Software developers, as a result, are in greater demand than ever, and that’s driving the push to automate some of the easier tasks that take up their time.  Productivity tools like Eclipse and Visual Studio suggest snippets of code that developers can easily drop into their work as they write. These automated features are powered by sophisticated language models...

A method to assess Covid-19 transmission risks...
Two MIT professors have proposed a new approach to estimating the risks of exposure to Covid-19 under different indoor settings. The guideline they developed suggests a limit for exposure time, based on the number of people, the size of the space, the kinds of activity, whether masks are worn, and the ventilation and filtration rates. Their model offers a detailed, physics-based guideline for policymakers, businesses, schools, and individuals trying to gauge their own risks. The guideline, appearing this week...

Counting pedestrians to make pedestrians count
A key portion of MIT’s campus overlaps with Kendall Square, the bustling area in East Cambridge where students, residents, and tech employees scurry around in between classes, meetings, and meals. Where are they all going? Is there a way to make sense of this daily flurry of foot traffic? In fact, there is: MIT Associate Professor Andres Sevtsuk has made Kendall Square the basis of a newly published model of pedestrian movement that could help planners and developers better...

An on-off switch for gene editing
Over the past decade, the CRISPR-Cas9 gene editing system has revolutionized genetic engineering, allowing scientists to make targeted changes to organisms’ DNA. While the system could potentially be useful in treating a variety of diseases, CRISPR-Cas9 editing involves cutting DNA strands, leading to permanent changes to the cell’s genetic material.  Now, in a paper published online in Cell on April 9, researchers describe a new gene editing technology called CRISPRoff that allows researchers to control gene expression with high...

Professor Emeritus Ernest Cravalho, an expert in...
Ernest “Ernie” Cravalho, professor emeritus of mechanical engineering at MIT, passed away on Tuesday, April 13, at the age of 82. Cravalho served as a member of MIT’s mechanical engineering faculty for 44 years. Along with his many research contributions in the fields of thermodynamics, heat transfer, and bioengineering, Cravalho helped shape MIT’s thermodynamics education into what it is today. Born in San Mateo, California, in 1939, Cravalho earned his bachelor’s degree, master’s degree, and PhD in mechanical engineering...

Fair ball! Sports analytics reckons with equity
Fairness is part of the promise of sports analytics. By judging an athlete’s performance through good data — as opposed to reputation, image, or outworn clichés — analytics creates the possibility that people can be judged more consistently on merit than often occurs elsewhere in life. But that promise of fairness only goes so far in a sports world shaped by the same social forces as everything else: Men’s sports have traditionally commanded more resources than women’s sports, including...

Fast-spinning black holes narrow the search for...
Ultralight bosons are hypothetical particles whose mass is predicted to be less than a billionth the mass of an electron. They interact relatively little with their surroundings and have thus far eluded searches to confirm their existence. If they exist, ultralight bosons such as axions would likely be a form of dark matter, the mysterious, invisible stuff that makes up 85 percent of the matter in the universe. Now, physicists at MIT’s LIGO Laboratory have searched for ultralight bosons...

Negative emissions, positive economy
The long-term goals of the Paris Agreement — keeping global warming well below 2 degrees Celsius and ideally 1.5 C in order to avert the worst impacts of climate change — may not be achievable by greenhouse gas emissions-reduction measures alone. Most scenarios for meeting these targets also require the deployment of negative emissions technologies (NETs) that remove carbon dioxide (CO2) from the atmosphere. A leading NET candidate is bioenergy with carbon capture and storage (BECCS), which extracts energy...

Job connectivity improves resiliency in US cities,...
What makes urban labor markets more resilient? This is the question at the heart of a new study published in Nature Communications by members of MIT’s Connection Science Group. The researchers in this study, including MIT research scientist and Universidad Carlos III (Spain) Professor Esteban Moro; University of Pittsburgh professor and former MIT postdoc Frank Morgan, MIT Professor Alex “Sandy” Pentland, and Max Planck professor and former MIT professor Iyad Rahwan, drew on prior network modeling research to map...

With “Choctaw Animals” for piano, Charles Shadle...
Charles Shadle was just 10 years old when he was entrusted with a precious family heirloom: a book of music that his great-great-great-grandmother had brought with her on the Trail of Tears, the forced removal of Native Americans to Oklahoma from their southeastern homelands beginning in the 1830s. Today, this extraordinary gift remains a symbol of two significant threads interwoven in Shadle’s life: music and his Choctaw heritage. “There was usually a person in every generation that music was...

The MIT Press has launched MIT Press Open Architecture and Urban Studies, a robust digital collection of classic and previously out-of-print architecture and urban studies books, on their digital book platform MIT Press Direct. The collection was funded by a grant from the Andrew W. Mellon Foundation as part of the Humanities Open Book Program, which they co-sponsored with the National Endowment for the Humanities. For years, the MIT Press has fielded requests for e-book editions of classic, out-of-print...
