Professor Emeritus Arnoldo Hax, who reprioritized corporate...
Arnoldo Hax, the Alfred P. Sloan Professor of Management Emeritus at the MIT Sloan School of Management and an operations management expert who introduced a customer-centered approach to competitive strategy with his Delta Model, died April 20. He was 87. Hax joined MIT Sloan in 1973 as a member of the Operations Management group. An industrial engineer who believed that management could be improved through rationalization, Hax was an early member of the strategy group at MIT Sloan, and...

A more effective way to train machines...
Someone learning to play tennis might hire a teacher to help them learn faster. Because this teacher is (hopefully) a great tennis player, there are times when trying to exactly mimic the teacher won’t help the student learn. Perhaps the teacher leaps high into the air to deftly return a volley. The student, unable to copy that, might instead try a few other moves on her own until she has mastered the skills she needs to return volleys. Computer...

New tool helps people choose the right...
When machine-learning models are deployed in real-world situations, perhaps to flag potential disease in X-rays for a radiologist to review, human users need to know when to trust the model’s predictions. But machine-learning models are so large and complex that even the scientists who design them don’t understand exactly how the models make predictions. So, they create techniques known as saliency methods that seek to explain model behavior. With new methods being released all the time, researchers from MIT...

CoCo: A real-time co-creative learning platform for...
CoCo is a new co-creative learning platform that empowers educators to engage children and teens in an endless variety of collaborative creative computing experiences with peers — regardless of whether they are sitting next to one another in a classroom or connecting remotely across continents. The platform supports real-time collaboration across multiple types of interactive environments, including those for block-based coding, text-based coding, digital art, and creative writing. The co-creative programming environments in CoCo currently extend and build on...

Facing up to democratic distrust
In October 2020, two rival candidates for office in Utah made an unusual television ad together. Incumbent Republican Gov. Spencer Cox and his Democratic challenger, Chris Peterson, appeared in the same spot to note they were both “dedicated to the American values of liberty, democracy, and justice for all people,” as Cox said, and that “our common values transcend our political differences,” as Peterson put it. Such reassurances are unusual, however, and can be overwhelmed by other messages. Indeed,...

A telescope’s last view
More than 5,000 planets are confirmed to exist beyond our solar system. Over half were discovered by NASA’s Kepler Space Telescope, a resilient observatory that far outlasted its original planned mission. Over nine and a half years, the spacecraft trailed the Earth, scanning the skies for periodic dips in starlight that could signal the presence of a planet crossing in front of its star. In its last days, the telescope kept recording the brightness of stars as it was...

Pamela Z: Singing the body electric
In the mid-1980s, artist Pamela Z was working at Tower Records on Columbus Street in San Francisco, where one of her jobs was replacing pages in the store’s Phonolog, an enormous alphabetized directory of all the music available at the time, which formed a kind of bible of pop. When she ripped one loose-leafed sheet from the book, she noticed that all the titles on that sheet began with “you.” You stayed on my mind. You stole my heart....

MIT undergraduates Rupert Li and Audrey Xie have been selected to receive Barry Goldwater Scholarships for the 2023-24 academic year. From an estimated pool of more than 5,000 college sophomores and juniors, nearly 1,300 students were nominated by 427 academic institutions to compete for the scholarship, with Li and Xie representing two of only 413 recipients selected based on academic merit. Since 1989, the Barry Goldwater Scholarship and Excellence in Education Foundation has awarded more than 10,000 Goldwater scholarships....

Celebrating the impact of IDSS
The “interdisciplinary approach” is something that has been lauded for decades for its ability to break down silos and create new integrated approaches to research. For Munther Dahleh, founding director of the MIT Institute for Data, Systems, and Society (IDSS), showing the community that data science and statistics can transcend individual disciplines and form a new holistic approach to addressing complex societal challenges has been crucial to the institute’s success. “From the very beginning, it was critical that we...

Tackling the MIT campus’s top energy consumers,...
When staff in MIT’s Department of Facilities would visualize energy use and carbon-associated emissions by campus buildings, Building 46 always stood out — attributed to its energy intensity, which accounted for 8 percent of MIT’s total campus energy use. This high energy draw was not surprising, as the building is home of the Brain and Cognitive Sciences Complex and a large amount of lab space, but it also made the building a perfect candidate for an energy performance audit...

Civil discourse project to launch at MIT
A new project on civil discourse aims to promote open and civil discussion of difficult topics on the MIT campus. The project, which will launch this fall, includes a speaker series and curricular activities in MIT’s Concourse program for first-year students. MIT philosophers Alex Byrne and Brad Skow from the Department of Linguistics and Philosophy lead the project, in close coordination with Anne McCants, professor of history and director of Concourse, and Linda Rabieh, a Concourse lecturer.  The Arthur...

Gravitational-wave detectors start next observing run to...
The following article is adapted from a press release issued by the Laser Interferometer Gravitational-wave Observatory (LIGO) Laboratory, in collaboration with the LIGO Scientific Collaboration and Virgo Collaboration. LIGO is funded by the National Science Foundation (NSF) and operated by Caltech and MIT, which conceived and built the project. On Wednesday, the LIGO-Virgo-KAGRA (LVK) collaboration began a new observing run with upgraded instruments, new and even more accurate signal models, and more advanced data analysis methods. The LVK collaboration consists of scientists...

Using an artificial intelligence algorithm, researchers at MIT and McMaster University have identified a new antibiotic that can kill a type of bacteria that is responsible for many drug-resistant infections. If developed for use in patients, the drug could help to combat Acinetobacter baumannii, a species of bacteria that is often found in hospitals and can lead to pneumonia, meningitis, and other serious infections. The microbe is also a leading cause of infections in wounded soldiers in Iraq and...

On April 24, MIT celebrated outstanding students and employees at the annual Change-Maker Awards for their diligent work to eradicate sexual misconduct and support survivors. These architects of positive change exemplify one of MIT’s core values: striving to make our community a more humane and welcoming place where all can thrive. Hosted by MIT Violence Prevention and Response (VPR) and the Institute Discrimination and Harassment Response Office (IDHR), the awards are held each April to coincide with Sexual Assault...

Helping robots handle fluids
Imagine you’re enjoying a picnic by a riverbank on a windy day. A gust of wind accidentally catches your paper napkin and lands on the water’s surface, quickly drifting away from you. You grab a nearby stick and carefully agitate the water to retrieve it, creating a series of small waves. These waves eventually push the napkin back toward the shore, so you grab it. In this scenario, the water acts as a medium for transmitting forces, enabling you...
