Superhero U

In a workshop filled with robotic limbs and several expensive cars, the clanging of a hammer rings out over the blasting sounds of AC/DC. Amid the clamor, a man with a glowing arc reactor in his chest is hard at work with help from J.A.R.V.I.S., an AI program of his own creation. On the man’s right hand shines a golden brass rat.

Tony Stark, better known as Iron Man, is perhaps the most iconic representative of MIT in Marvel comics and movies. In Iron Man’s first appearance, in Tales of Suspense #39 (1963), the millionaire inventor of high-end weapons and CEO of Stark Industries is kidnapped by a warlord who wants him to build a superweapon. After crafting an armored robotic suit instead—a suit that allows him to escape his captors—he realizes the harm his company is inflicting. So Stark eventually shifts his focus to more humanitarian projects and embraces the persona of a tech-assisted superhero.

The brass rat Stark wears in the 2008 movie Iron Man is no coincidence. Readers of the 1996 comic Iron Man: The Legend learn that he graduated from MIT at 17 with a double major in physics and engineering—an impressive but not completely beyond-the-realm-of-possibility feat at MIT in real life. (His status as valedictorian and summa cum laude graduate, however, is of course pure fiction; the real MIT doesn’t bestow these honors.) 

The Marvel Cinematic Universe (MCU) packs in multiple additional references to Stark’s MIT education. In Iron Man, a montage shows Stark on the cover of MIT Technology Review as a student, and the Institute calls on him to give a commencement speech; in Captain America: Civil War, Stark establishes the September Foundation, which funds the education of prodigies, in an MIT auditorium that looks a lot like Kresge. He also meets his best friend, James Rhodes, at MIT; both are seen wearing the iconic MIT rings known as brass rats in Iron Man. It’s likely that Marvel’s writers gave Stark an MIT backstory to make his creation of such a sophisticated full-body robotic suit seem plausible, since such technology is as yet unachievable in the real world.

How did MIT come to symbolize technological genius? While it may seem strange to ask such a question, the Institute wasn’t always as famous as it is today. “Scientists, engineers, and industrial leaders of course knew of MIT, but widespread public attention really accelerated in the mid-20th century,” says Deborah Douglas, director of collections and curator of science and technology at the MIT Museum. Doc Edgerton’s famous high-speed photos, MIT’s role in the development of radar during World War II, and the Instrumentation Lab’s contributions to the Apollo space program in the 1960s raised the Institute’s public profile, as did WGBH’s television series MIT Science Reporter in the late 1960s and early 1970s. Then media coverage of the MIT Daedalus Project, which in 1988 re-created the mythical flight of Daedalus by flying a human-powered aircraft between the islands of Crete and Santorini, “began to create awareness that extended well beyond the Boston Globe or the usual publications,” she says. “MIT had never received that kind of public attention, and it vaulted the Institute into a level of public recognition globally that it had never known before.” 

MIT has become a pop-culture icon. “It’s a kind of shorthand. The writer doesn’t have to go to great lengths to prove that this character is smart or knows something about science.”
-Deborah Douglas

As MIT has become more widely known, it has also become a pop-culture icon. “It’s a kind of shorthand,” Douglas says. “The writer doesn’t have to go to great lengths to prove that this character is smart or knows something about science, at risk of boring the audience.” Marvel in particular uses this MIT shorthand to make fantastical technology, such as arc reactors and robotic suits that give their wearers the ability to fly, seem believable. Having an MIT genius behind these creations is an easy way to explain the unexplained. That’s particularly useful for comic book writers, who need to say a lot in a few words to leave plenty of room for illustrations.  

The convenience of the “MIT = genius” trope—and the popularity of Iron Man—led Marvel to create two other MIT heroes with robotic suits who recently made appearances on the silver screen.

Shortly after being unmasked as Spider-Man and accused of murdering Mysterio, Peter Parker swings into a coffee shop, a piece of mail clutched tightly in his hand, to find his friends MJ Watson and Ned Leeds so they can all open their letters from MIT Admissions together. Their anticipation fades as they read, “In light of recent controversy, we are unable to consider your application at this time.” 

In Spider-Man: No Way Home (2021), Parker—a.k.a. Spider-Man—was confident that, having been mentored by Tony Stark, he had a good shot of getting into MIT. With access to Stark’s resources, Parker had gone from using homemade web shooters to designing a suit enhanced by nanotechnology. And he certainly had the academic credentials, having attended the highly competitive (fictional) Midtown School of Science and Technology and developed his skills as Spider-Man. So when he isn’t accepted, Parker launches a crusade to have MIT Admissions reconsider. The movie’s plot aligns with the reality that MIT does not consider a student’s connections or legacy status in admissions decisions. As Chris Peterson, SM ’13, of the MIT Admissions Office explained in a 2012 blog post, “There is only one way into (and out of) MIT, and that’s the hard way.”

Another Iron Man protégé didn’t try to use the superhero’s help to get into MIT because she had already been a student there before meeting him. In Invincible Iron Man Vol. 3, #7 (2016), 15-year-old Riri Williams works late into the night in Simmons Hall, making a replica of the Iron Man suit. Much to the dismay of campus security, Riri helps herself to property from a robotics lab, skips classes, and draws several noise complaints for her work. To avoid repercussions, she flies off in her suit, meets Iron Man, and earns the moniker Ironheart. In real life, Marvel arranged to temporarily close Massachusetts Avenue in 2021 to film several scenes—including some with Riri—for Black Panther: Wakanda Forever. The character is slated to have her own show on Disney+, but the timing of its release is uncertain, given the strikes in Hollywood.

In between Tony Stark and Riri Williams, another set of MIT students also made a brief appearance in the Marvel universe.

One late autumn night in Cambridge, Massachusetts, the MIT chairman’s office is abuzz with activity. It is not occupied by its owner, but instead by a group of students and a half-assembled tractor. Despite their precautions to avoid the night watchman, their professor catches the hackers mid-prank—and distracts the approaching chairman so that they can flee on the ledges of the building’s exterior.

Nearly 20 years after Iron Man’s debut in the comics but long before he showed up on the silver screen as an MIT alum, MIT figured prominently in another Marvel series. Spitfire and the Troubleshooters, a short-lived 1980s title, introduces readers to a motley crew of five MIT undergraduates and their structural engineering professor, Jennifer Swensen. The students, known as the Troubleshooters, assist Swensen in her quest to rescue the robotic “Spitfire” suit that her father invented to help construction workers—before it becomes militarized by her father’s murderer. To do this, the Troubleshooters draw upon their hacking skills, which they’d previously honed to construct that tractor and later to sabotage the opposing crew team during an MIT-Yale race. 

The hacking hijinks chronicled in Spitfire and the Troubleshooters were inspired by author Eliot R. Brown’s trips to MIT to visit a student who’d been his childhood friend. During those visits, they “would run around on the rooftops” and “break into rooms and swipe ladders and climb up the sides of buildings,” Brown told the comics magazine Back Issue! in 2009. In addition to depicting the MIT campus, Brown and his coauthors aimed to present a more realistic version of the whole robotic-suit idea. “It was more than ‘Iron Girl’—it was a different technological attitude, more reality-based. Iron Man was not unreal, but Iron Man as a concept did too much,” Brown explained in the Back Issue! interview. “I tried to do something that was more of a garbage can with legs and a good brain in it, something more mechanical.” While Brown’s depiction of MIT characters and their exploits was comparatively true to life, some of the Troubleshooters’ actions violate two of the hacking principles listed in MIT’s Mind and Hand Book: leave no damage and do not steal anything. But then again, not all MIT characters in the Marvel Universe have the world’s best interests at heart.

Inside a darkened MIT lab space with a “RESTRICTED” sign on the door, a student is filling chalkboards with complex equations inspired by his classroom lectures. A professor enters the room, outraged at this student’s unauthorized presence. But the ingenious calculations on the wall draw him to halt and lead him to offer the student, Otto Octavius, a research opportunity with his lab. 

Stories like those of Iron Man, Riri, and the Troubleshooters counter­balance what can be the unglamorous reality of working to advance knowledge and educate students.

Readers of the Spider-Man/Doctor Octopus: Year 1 comic series learn that Octavius conducted extensive nuclear research while an undergraduate at MIT, just as MIT’s Undergraduate Research Opportunities Program (UROP) lets undergrads work on meaningful research in real life. Octavius’s work is funded in part by the government and gives him an accelerated track to a doctorate. But when one of his experiments goes awry, Octavius’s mind is warped, and he gains four robotic arms that assist in his new life of crime as the evil Doctor Octopus (or Doc Ock for short).

Several other Marvel villains also have MIT credentials. In Iron Man Vol. 3 (1999), readers find out that Sunset Bain (Madame Menace) attended MIT at the same time as Stark. Bad guys Quentin Beck (a.k.a. Mysterio) and Dr. Jonathan Ohnn (a.k.a. the Spot, because he can teleport through spots on his body) are noted to have been roommates at MIT in Symbiote Spider-Man Vol. 1, #1. In an alternate universe in the Disney+ show What If … ?, Tony Stark’s friend Rhodey does a background check into Erik Stevens (the villain known as Killmonger) and finds out that he attended MIT. 

Like most MIT alumni, these villains have a knack for science and engineering. Mysterio uses chemistry to develop convincing special effects for evil purposes, Killmonger leverages his extensive knowledge of weaponry, and Doc Ock wields his robotic arms to wreak havoc on New York, often attempting to steal research equipment. Since they use their technical skills for evil, it would seem that Marvel villains flout a core tenet of the MIT values statement: “Together we possess uncommon strengths, and we shoulder the responsibility to use them with wisdom and care for humanity and the natural world.”

Not all these evil characters with MIT backstories are doomed to a life of villainy, though. In one story arc from 2013, Octavius switches minds with Peter Parker to escape his imminent death from cancer. But with the dying wish of Parker, Octavius adopts a new identity as Superior Spider-Man. In this second chance at life, he founds Parker Industries, a conglomerate whose work includes developing cybernetic prosthetics and biomedical devices, and finds a girlfriend, Anna Maria Marconi. Long after Octavius relinquishes Parker’s body to its original host to save Marconi, she asks Parker if Octavius was “a good man who did bad things, a bad man who did good things, or a bit of both.” Complex and nuanced characters like this show that even those with a track record of evil have the potential to change their ways and contribute to the world.

Marvel’s sometimes extreme versions of MIT students make for engaging, and often inspiring, stories. And the Institute’s prominent role in the Marvel Cinematic Universe has clearly evoked pride in the MIT community. In 2019, students adorned the Lobby 10 dome with the Captain America shield when Avengers: Endgame hit the theaters. And in 2022, they raised Wakanda Forever banners above the entrance at 77 Mass. Ave. to mark the release of the Black Panther sequel. Riri Williams, who appears on murals around campus and is depicted on the Class of 2020 brass rat, was featured in the MIT Admissions Office’s Pi Day 2017 video (in which she was played by Ayomide Fatunde ’18), generating a lot of media coverage and breaking Admissions Office video viewership records. Several professors have also referenced Marvel in their class assignments. For example, in 2023’s 2.007 Design and Manufacturing class, students designed robots that competed in a challenge called Machina Forever. When Wakanda Forever was released, the MIT Lecture Series Committee screened it in 26-100, and class councils rented theaters to see the film. And Robert Downey Jr., the actor who played Iron Man, visited campus—and met with Professor Hugh Herr in MIT’s Y. Lisa Yang Center for Bionics—in the summer of 2022.

The real-world impact of MIT’s recurring role in Marvel story arcs goes beyond scenes filmed on campus and Marvel-inspired hacks. The complexity of the MIT characters reminds viewers and readers that not all MIT students are cut from the same cloth. And the range of heroes, villains, and those in between shows that everyone can make an impact. But equally important, stories like those of Iron Man, Riri, and the Troubleshooters counterbalance what can be the unglamorous reality of working to advance knowledge and educate students. These tales highlight what is exciting about science and technology—and just might inspire the inventors and innovators of tomorrow. As Douglas says, “We don’t like our stories about committees. We like our stories about heroes and heroines.” 

Barbie meets Dr. Who

On the first day of fall class registration, a Barbie-themed TARDIS, the time-traveling spaceship from Doctor Who, appeared in the president’s office, courtesy of incoming first-years in Interphase EDGE/x, a scholar enrichment program run by the Office of Minority Education. Inside the “Barbis,” President Kornbluth found a web of mirrors and lights representing infinite space travel.

Barbis was constructed over the summer during an eight-week Interphase EDGE/x course at the MIT Edgerton Center. In the class, students form project teams and envision and complete a project, gaining hands-on engineering skills as they get to know other first-years. Read more about the Barbis project here.

Tuning in

I’ve written to you before about the experience of reviewing young faculty up for promotion—in my very first week as the Institute’s president. It was an intoxicating introduction to the human potential of MIT. 

Getting this kind of preview of MIT’s intellectual future was so inspiring I thought we ought to find a way to share it. I also wanted to understand more about our newly tenured faculty—their backgrounds, their career paths, their take on life at MIT. Why not chat with them directly and let the world listen in? So the podcast Curiosity Unbounded was born.

In the first episode, released last spring, I interviewed Desirée Plata, associate professor of civil and environmental engineering. We talked about her work on the very hard problem of removing methane from the atmosphere and her experience raising four children while earning tenure at MIT.

Since then we’ve recorded five more episodes, and it’s been an absolute joy to spend time with these brilliant teachers and researchers, delving into their discoveries in fields from political science to engineering to geobiology. Our discussions touched on climate solutions, AI opportunities, family histories, and the relationship between life and work (is it a balance or an intermingling?). 

Each of my guests spoke openly and enthusiastically, and in spite of the differences in their expertise and interests, they all conveyed their joy at having found a home at MIT. I feel that way too. For any intellectually curious person, there’s nothing better than a place where you can ask a question on nearly any topic and find someone who’s an expert on that very thing—and willing to share what they know. 

After each conversation, I left the studio with interesting new facts and ideas to explore—and a powerful feeling of hope. The dedication of these passionate, creative faculty makes me highly optimistic about MIT’s capacity to do big things for the world.

I hope you’ll tune in for lively discussion, inspiring insights, and a glimpse into the future of knowledge and the future of MIT.

Stay curious!

A clever shield against photo fakery

Remember that selfie you posted last week? There’s currently nothing stopping someone from taking it and editing it with AI—and it might be impossible to prove that the resulting image is fake. 

The good news is that a new tool created by researchers at MIT could prevent this.

The tool, called PhotoGuard, works like a protective shield by altering photos in tiny ways that are invisible to the human eye but prevent them from being manipulated. If someone tries to use an editing app based on a generative AI model such as Stable Diffusion to manipulate an image that has been “immunized” by PhotoGuard, the result will look unrealistic or warped. 

Right now, “anyone can take our image, modify it however they want, put us in very bad-looking situations, and blackmail us,” says Hadi Salman, a PhD student at MIT who contributed to the research. PhotoGuard is “an attempt to solve the problem of our images being manipulated maliciously by these models,” says Salman. The tool could, for example, help prevent women’s selfies from being made into nonconsensual deepfake pornography.

The MIT team used two different techniques to stop images from being edited using Stable Diffusion. In the first, PhotoGuard adds imperceptible signals to the image so that the AI model interprets it as something else, such as a block of pure gray. In the second, it disrupts the way the AI models generate images, essentially by encoding them with secret signals that alter how they’re processed by the model, so any edited image looks like that gray block. For now, the technique works reliably only on Stable Diffusion, an open-source image generation model. 

In theory, people could apply this protective shield to their images before they upload them online, says Aleksander Madry, SM ’09, PhD ’11, a professor of electrical engineering and computer science who contributed to the research. But a more effective approach, he adds, would be for tech companies to add it to images that people upload into their platforms automatically—though it’s an arms race, because new AI models that might be able to override any new protections are always coming out.

Do-it-yourself breast ultrasound

Early detection is key to surviving breast cancer, but tumors that develop in between routine mammograms—known as interval cancers—tend to be especially aggressive. A wearable ultrasound device devised by MIT researchers could help detect such tumors when they are still in early stages. 

The device can be attached to a specialized bra to let an ultrasound tracker image the breast tissue from different angles. In their study, the researchers showed that they could obtain images comparable in resolution to those done at medical imaging centers.

“We changed the form factor of the ultrasound technology so that it can be used in your home. It’s portable and easy to use, and provides real-time, user-friendly monitoring of breast tissue,” says Canan Dagdeviren, an associate professor in MIT’s Media Lab and the senior author of the study. Dagdeviren drew up the first rough schematic of the device as an MIT postdoc at the bedside of her aunt Fatma Caliskanoglu, who (despite regular screenings) died of breast cancer six months after receiving a diagnosis at age 49. 

“My goal is to target the people who are most likely to develop interval cancer,” says Dagdeviren, whose research group specializes in developing wearable electronic devices. “With more frequent screening, our goal is to increase the survival rate to up to 98%.”

To make her vision of a diagnostic bra a reality, Dagdeviren designed a scanner that’s based on the same kind of technology used in medical imaging centers but can be much smaller thanks to the use of a novel piezoelectric material.

To make the device wearable, the researchers designed a flexible, 3D-printed patch, which has honeycomb-like openings. Using magnets, this patch can be attached to a bra with openings that allow the ultrasound scanner to contact the skin. The scanner fits inside a small tracker that can be moved to six different positions, and it can be rotated to take images from different angles. It does not require any special expertise to operate.

Working with the MIT Center for Clinical and Translational Research, the researchers tested their device on a 71-year-old woman with a history of breast cysts and succeeded in detecting cysts as small as 0.3 centimeters in diameter—the size of early-stage tumors. The patch can be used over and over, and the researchers envision that it could be used at home by people at high risk for breast cancer. It could also help diagnose cancer in people who don’t have regular access to screening.

Today, the researchers have to connect the device to a traditional ultrasound machine to view the images. But they are working to develop a smartphone-size version of the system used to read ultrasound scans, so that patients wouldn’t have to visit an imaging center.

Eventually, artificial intelligence might be used to analyze how the images change over time, which could be more accurate than relying on the assessment of a radiologist comparing images taken years apart. The researchers also plan to explore adapting the ultrasound technology to other parts of the body. 

Low-power underwater communication

MIT researchers have demonstrated a technology that can transmit underwater signals much farther than existing methods, using only about a millionth as much power. 

The system is based on backscatter communication, a method of encoding data in sound waves that are reflected from the sound source, or interrogator, back to a receiver in the same location. The underwater backscatter device uses nodes made from piezoelectric materials, which produce an electrical signal when a mechanical force—including sound waves—is applied. The nodes use that charge to scatter some of the acoustic energy back to the receiver.

To make the system more efficient, the researchers used a 70-year-old technology called a Van Atta array, in which symmetric pairs of antennas are connected so that energy is reflected back in the direction it came from, and placed a transformer between pairs of connected nodes. It can be used with data-collecting sensors and send data to a ship or onshore station.

In tests, the device achieved ranges of 300 meters, more than 15 times longer than previously demonstrated—and a model suggests that kilometer-scale ranges are possible. That could make it suitable for things like coastal hurricane prediction and climate modeling.

“There are still a few interesting technical challenges to address, but there is a clear path from where we are now to deployment,” says Fadel Adib, director of the Signal Kinetics group in the MIT Media Lab and the senior author of two papers on the work.

Energy-storing concrete

A supercapacitor made from cement and carbon black (a conductive material resembling fine charcoal) could form the basis for a low-cost way to store energy from renewable sources, according to MIT researchers.

The amount of power a capacitor can store depends on the total surface area of its conductive plates. Professors Franz-Josef Ulm, Admir Masic, and Yang Shao-Horn and colleagues found that if carbon black is introduced into a mixture with cement powder and water, the water naturally forms a branching network of openings when the resulting concrete cures—and the carbon migrates into that network to make wire-like structures, yielding a conductive material with an extremely large internal surface area. 

Two electrodes made by soaking this material in a standard electrolyte, separated by a thin space or an insulating layer, form a very powerful supercapacitor, the researchers found. A cube about 3.5 meters across could store about 10 kilowatt-hours.

The simple technology could eventually be incorporated into the concrete foundation of a house, where it could store a day’s worth of energy. The researchers also envision a roadway that could provide contactless recharging for electric cars as they travel.

It’s “a new way of looking toward the future of concrete as part of the energy transition,” Ulm says. 

AI-tocracy

It’s often believed that authoritarian governments resist technical innovation in a way that ultimately weakens them both politically and economically. But a more complicated story emerges from a new study on how China has embraced AI-driven facial recognition as a tool of repression. 

“What we found is that in regions of China where there is more unrest, that leads to greater government procurement of facial-recognition AI,” says coauthor Martin Beraja, an MIT economist. Not only has use of the technology apparently worked to suppress dissent, but it has spurred software development. The scholars call this mutually reinforcing situation an “AI-tocracy.” 

In fact, they found, firms that were granted a government contract for facial-recognition technologies produce about 49% more software products in the two years after gaining the contract than before. “We examine if this leads to greater innovation by facial-recognition AI firms, and indeed it does,” Beraja says.

Adding it all up, the case of China indicates how autocratic governments can potentially find their political power enhanced, rather than upended, when they harness technological advances—and even generate more economic growth than they would have otherwise.

The scholars are now studying the extent to which China is exporting facial-recognition tech around the world—highlighting a mechanism through which government repression could grow globally.
