Bringing together the next generation of quantum...
California Polytechnic State University undergraduate students Alexander Knapen and Nayana Tiwari and graduate student Julian Rice had never programmed on quantum computers before. But after 50 hours at the 2022 MIT Interdisciplinary Quantum Hackathon, they had built an online quantum chat server that encrypts messages using quantum algorithms. Knapen, Tiwari, and Rice had worked tirelessly on the chat server over an adrenaline-fueled weekend at the third annual iQuHACK (pronounced “i-quack”, like the duck in the hackathon’s logo). At iQuHACK,...

Robots dress humans without the full picture
Robots are already adept at certain things, such as lifting objects that are too heavy or cumbersome for people to manage. Another application they’re well suited for is the precision assembly of items like watches that have large numbers of tiny parts — some so small they can barely be seen with the naked eye. “Much harder are tasks that require situational awareness, involving almost instantaneous adaptations to changing circumstances in the environment,” explains Theodoros Stouraitis, a visiting scientist...

Study reveals the dynamics of human milk...
For the first time, MIT researchers have performed a large-scale, high-resolution study of the cells in breast milk, allowing them to track how these cells change over time in nursing mothers. By analyzing human breast milk produced between three days and nearly two years after childbirth, the researchers were able to identify a variety of changes in gene expression in mammary gland cells. Some of these changes were linked to factors such as hormone levels, illness of the mother...

What Russia’s invasion of Ukraine means for...
Russia’s invasion of Ukraine has global implications. A panel of MIT foreign policy experts convened on Monday to examine those reverberations — on European domestic politics, the refugee crisis, great-power relations, and nuclear security. Currently Ukraine has experienced widespread devastation, and millions of Ukrainians have fled their homes as refugees. Many countries have allied to enact stiff sanctions on Russia, and global sentiment has been with Ukraine. But as Monday’s discussion made clear, the global effects of the war...

System helps severely motor-impaired individuals type more...
In 1995, French fashion magazine editor Jean-Dominique Bauby suffered a seizure while driving a car, which left him with a condition known as locked-in syndrome, a neurological disease in which the patient is completely paralyzed and can only move muscles that control the eyes. Bauby, who had signed a book contract shortly before his accident, wrote the memoir “The Diving Bell and the Butterfly” using a dictation system in which his speech therapist recited the alphabet and he would...

SeXX and Immunity event raises crucial questions...
Why are females more likely to survive Covid-19 but at greater risk of developing chronic disease? Historically, why have women and nonbinary people typically been excluded from clinical trials? How do we understand how sex differences affect everyone? What is the interplay between sex chromosomes and sex hormones? Why has it taken the scientific community so long to include sex as a biological variable in research and analysis as a routine matter of course? These were a few of the...

School of Engineering welcomes Thomas Tull as...
Thomas Tull, leading visionary entrepreneur and investor, has been appointed a School of Engineering visiting innovation scholar, effective April 1. Throughout his career, Tull has leveraged the power of technology, artificial intelligence, and data science to disrupt and revolutionize disparate industries. Today, as the founder, chair, and CEO of Tulco LLC, a privately held holding company, he looks to partner with companies employing cutting-edge ideas in industries that are established but often underfunded and under-innovated. Under Tull’s leadership Tulco...

At MIT, women take the lead on...
MIT junior Cameron Kokesh crawled out of her tent on July 27, 2021, exhausted from 17-hour workdays in the Kansas summer heat. The MIT Solar Electric Vehicle team captain and about 24 other members were camping at the Formula Sun Grand Prix, where they would race their hand-built car against eight other teams to qualify for the American Solar Challenge. Kokesh and her teammates made their way to the track bathroom facilities to prepare for a big day. As...

Chemical reactions for the energy transition
One challenge in decarbonizing the energy system is knowing how to deal with new types of fuels. Traditional fuels such as natural gas and oil can be combined with other materials and then heated to high temperatures so they chemically react to produce other useful fuels or substances, or even energy to do work. But new materials such as biofuels can’t take as much heat without breaking down. A key ingredient in such chemical reactions is a specially designed...

Culture is a meaning-making practice
In this commentary, Heather Paxson, the William Kenan Jr. Professor of Anthropology, and head of MIT Anthropology, provides foundational thinking about how her field of anthropology — the scientific study of humanity including societies, behavior, cultural meaning, norms, and values — understands the concept of culture. This article is the first in a series in which faculty and staff share ideas, stories, and research-based commentary on the nature of culture and their experiences as part of the MIT community....

Neurons are fickle. Electric fields are more...
As the brain strives to hold information in mind, such as the list of groceries we need to buy on the way home, a new study suggests that the most consistent and reliable representation of that information is not the electrical activity of the individual neurons involved, but an overall electric field they collectively produce. Indeed, whenever neuroscientists have looked at how brains represent information in working memory, they’ve found that from one trial to the next, even when...

Dan Huttenlocher ponders our human future in...
What does it mean to be human in an age where artificial intelligence agents make decisions that shape human actions? That’s a deep question with no easy answers, and it’s been on the mind of Dan Huttenlocher SM ’84, PhD ’88, dean of the MIT Schwarzman College of Computing, for the past few years. “Advances in AI are going to happen, but the destination that we get to with those advances is up to us, and it is far...

Generating new molecules with graph grammar
Chemical engineers and materials scientists are constantly looking for the next revolutionary material, chemical, and drug. The rise of machine-learning approaches is expediting the discovery process, which could otherwise take years. “Ideally, the goal is to train a machine-learning model on a few existing chemical samples and then allow it to produce as many manufacturable molecules of the same class as possible, with predictable physical properties,” says Wojciech Matusik, professor of electrical engineering and computer science at MIT. “If...

“Diverse people lead to diverse ideas”
Smells of steak, vegetables, and onions filled the air, the sizzle complementing sounds of laughter and music. Students from a variety of Black student groups on campus came together to mingle and relax, enjoying the nice spring weather and community. Surveying the scene with satisfaction was Devin Johnson, an aeronautical and astronautical engineering major and an executive board member of the Black Students’ Union. He had helped organize the event and was proud to have created a space where...
