The MIT Department of Materials Science and Engineering Breakerspace transformed into an art gallery on March 10, with six easels arranged in an arc to showcase arresting images — black-and-white scanning electron microscope (SEM) images of crumpled biological structures alongside the brilliant hues of digital optical microscopy.

The images were the winning entries from the inaugural Breakerspace Microscope Image Contest, which opened in fall 2024. The contest invited all MIT undergraduates to train on the Breakerspace’s microscopic instruments, explore material samples, and capture images that were artistic, instructive, or technically challenging.

“The goal of the contest is to inspire curiosity and creativity, encouraging students to explore the imaging tools in the Breakerspace,” says Professor Jeffrey Grossman of the Department of Materials Science and Engineering (DMSE). “We want students to see the beauty and complexity of materials at the microscopic level, to think critically about the images they capture, and to communicate what they mean to others.”

Grossman was a driving force behind the Breakerspace, a laboratory and lounge designed to encourage MIT undergraduates to explore the world of materials.

The contest drew about 50 entries across four categories:

• Most Instructive, for images illustrating key concepts with documentation
• Most Challenging, requiring significant sample preparation
• Best Optical Microscope Image of a sample, rendered in color
• Best Electron Microscope Image, magnified hundreds or even thousands of times

Winners in the four categories received $500, and two runners-up received $100.

“By making this a competition with prizes, we hope to motivate more students to explore microscopy and develop a stronger connection to the materials science community at MIT,” Grossman says.

A window onto research

Amelia How, a DMSE sophomore and winner of the Most Instructive category, used an SEM to show how hydrogen atoms seep into titanium — a phenomenon called hydrogen embrittlement, which can weaken metals and lead to material failure in applications such as aerospace, energy, or construction. The image stemmed from How’s research in Associate Professor Cem Tasan’s research lab, through MIT’s Undergraduate Research Opportunities Program (UROP). She trained on the SEM for the contest after seeing an email announcement.

“It helped me realize how to explain what I was actually doing,” How says, “because the work that I’m doing is something that’s going into a paper, but most people won’t end up reading that.”

Mishael Quraishi, a DMSE senior and winner of Best SEM Image, captured the flower Alstroemeria and its pollen-bearing structure, the anther. She entered the contest mainly to explore microscopy — but sharing that experience was just as rewarding.

“I really love how electron images look,” Quraishi says. “But as I was taking the images, I was also able to show people what pollen looked like at a really small scale — it’s kind of unrecognizable. That was the most fun part: sharing the image and then telling people about the technique.”

Quraishi, president of the Society of Undergraduate Materials Scientists, also organized the event, part of Materials Week, a student-run initiative that highlights the department’s people, research, and impact.

Persistence in practice

The winner of the Most Challenging category, DMSE sophomore Nelushi Vithanachchi gained not just microscopy experience, but also perseverance. The category called for significant effort put into the sample preparation — and Vithanachchi spent hours troubleshooting.

Her sample — a carving of MIT’s Great Dome in silicon carbide — was made using a focused ion beam, a tool that sculpts materials by bombarding them with ions, or charged atoms. The process requires precision, as even minor shifts can ruin a sample.

In her first attempt, while milling the dome’s façade, the sample shifted and broke. A second try with a different design also failed. She credits her UROP advisor, Aaditya Bhat from Associate Professor James LeBeau’s research group, for pushing her to keep going.

“It was four in the morning, and after failing for the third time, I said, ‘I’m not doing this,’” Vithanachchi recalls. “Then Aaditya said, ‘No, we’ve got to finish what we started.’” After a fourth attempt, using the lessons learned from the previous failures, they were finally able to create a structure that resembled the MIT dome.

Anna Beck, a DMSE sophomore and runner-up for Best Electron Microscope Image, had a much different experience. “It was very relaxed for me. I just sat down and took images,” she says. Her entry was an SEM image of high-density polyethylene (HDPE) fibers from an event wrist band. HDPE is a durable material used in packaging, plumbing, and consumer goods.

Through the process, Beck gained insight into composition and microscopy techniques — and she’s excited to apply what she’s learned in the next competition in fall 2025. “In hindsight, I look at mine now and I wish I turned the brightness up a little more.”

Although 35 percent of the entries came from DMSE students, a majority — 65 percent — came from other majors, or first-year students.

With the first contest showcasing both creativity and technical skill, organizers hope even more students will take on the challenge, bringing fresh perspectives and discoveries to the microscopic world. The contest will run again in fall 2025.

“The inaugural contest brought in an incredible range of submissions. It was exciting to see students engage with microscopy in new ways and share their discoveries,” Grossman says. “The Breakerspace was designed for all undergraduates, regardless of major or experience level — whether they’re conducting research, exploring new materials, or simply curious about what something is made of. We’re excited to expand participation and encourage even more entries in the next competition.”

The Federal Laboratory Consortium (FLC) has awarded MIT Lincoln Laboratory a 2025 FLC Excellence in Technology Transfer Award. The award recognizes the laboratory's exceptional efforts in commercializing microwave sounders hosted on small satellites called CubeSats. The laboratory first developed the technology for NASA, demonstrating that such satellites could work in tandem to collect hurricane data more frequently than previously possible and significantly improve hurricane forecasts. The technology is now licensed to the company Tomorrow.io, which will launch a large constellation of the sounder-equipped satellites to enhance hurricane prediction and expand global weather coverage. 

"This FLC award recognizes a technology with significant impact, one that could enhance hourly weather forecasting for aviation, logistics, agriculture, and emergency management, and highlights the laboratory's important role in bringing federally funded innovation to the commercial sector," says Asha Rajagopal, Lincoln Laboratory's chief technology transfer officer.

A nationwide network of more than 300 government laboratories, agencies, and research centers, the FLC helps facilitate the transfer of technologies out of federal labs and into the marketplace to benefit the U.S. economy, society, and national security.

Lincoln Laboratory originally proposed and demonstrated the technology for NASA's TROPICS (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of SmallSats) mission. For TROPICS, the laboratory put its microwave sounders on low-cost, commercially available CubeSats for the first time.

Of all the technology used for sensing hurricanes, microwave sounders provide the greatest improvement to forecasting models. From space, these instruments detect a range of microwave frequencies that penetrate clouds, allowing them to measure 3D temperature, humidity, and precipitation in a storm. State-of-the-art instruments are typically large (the size of a washing machine) and hosted aboard $2 billion polar-orbiting satellites, which collectively may revisit a storm every six hours. If sounders could be miniaturized, laboratory researchers imagined, then they could be put on small satellites and launched in large numbers, working together to revisit storms more often.

The TROPICS sounder is the size of a coffee cup. The laboratory team worked for several years to develop and demonstrate the technology that resulted in a miniaturized instrument, while maintaining performance on par with traditional sounders for the frequencies that provide the most useful tropical cyclone observations. By 2023, NASA launched a constellation of four TROPICS satellites, which have since collected rapidly refreshed data of many tropical storms.

Now, Tomorrow.io plans to increase that constellation to a global network of 18 satellites. The resulting high-rate observations — under an hour — are expected to improve weather forecasts, hurricane tracking, and early-warning systems.

"This partnership with Tomorrow.io expands the impact of the TROPICS mission. Tomorrow.io’s increased constellation size, software pipeline, and resilient business model enable it to support a number of commercial and government organizations. This transfer to industry has resulted in a self-sustaining national capability, one that is expected to help the economy and the government for years to come," says Tom Roy, who managed the transfer of the technology to Tomorrow.io.

The technology transfer spanned 18 months. Under a cooperative research and development agreement (CRADA), the laboratory team adapted the TROPICS payload to an updated satellite design and delivered to Tomorrow.io the first three units, two of which were launched in September 2024. The team also provided in-depth training to Tomorrow.io and seven industry partners who will build, test, launch, and operate the future full commercial constellation. The remaining satellites are expected to launch before the end of this year.

"With these microwave sounders, we can set a new standard in atmospheric data collection and prediction. This technology allows us to capture atmospheric data with exceptional accuracy, especially over oceans and remote areas where traditional observations are scarce," said Rei Goffer, co-founder of Tomorrow.io, in a press release announcing the September launches.

Tomorrow.io will use the sounder data as input into their weather forecasts, data products, and decision support tools available to their customers, who range from major airlines to governments. Tomorrow.io's nonprofit partner, TomorrowNow, also plans to use the data as input to its climate model for improving food security in Africa.

This technology is especially relevant as hurricanes and severe weather events continue to cause significant destruction. In 2024, the United States experienced a near-record 27 disaster events that each exceeded $1 billion in damage, resulting in a total cost of approximately $182.7 billion, and that caused the deaths of at least 568 people. Globally, these storm systems cause thousands of deaths and billions of dollars in damage each year.

“It has been great to see the Lincoln Laboratory, Tomorrow.io, and industry partner teams work together so effectively to rapidly incorporate the TROPICS technology and bring the new Tomorrow.io microwave sounder constellation online,” says Bill Blackwell, principal investigator of the NASA TROPICS mission and the CRADA with Tomorrow.io. “I expect that the improved revisit rate provided by the Tomorrow.io constellation will drive further improvements in hurricane forecasting performance over and above what has already been demonstrated by TROPICS.”

The team behind the transfer includes Tom Roy, Bill Blackwell, Steven Gillmer, Rebecca Keenan, Nick Zorn, and Mike DiLiberto of Lincoln Laboratory and Kai Lemay, Scott Williams, Emma Watson, and Jan Wicha of Tomorrow.io. Lincoln Laboratory will be honored among other winners of 2025 FLC Awards at the FLC National Meeting to be held virtually on May 13.

LEGOs are no stranger to many members of the MIT community. Faculty, staff, and students, alike, have developed a love of building and mechanics while playing with the familiar plastic bricks. In just a few hours, a heap of bricks can become a house, a ship, an airplane, or a cat. The simplicity lends itself to creativity and ingenuity, and it has inspired many MIT faculty members to bring LEGOs into the classroom, including class 2.S00 (Introduction to Manufacturing), where students use LEGO bricks to learn about manufacturing processes and systems.

It was perhaps no surprise, then, that the lecture hall in the MIT Schwarzman College of Computing was packed with students, faculty, staff, and guests to hear Carsten Rasmussen, chief operating officer of the LEGO Group, speak as part of the Manufacturing@MIT Distinguished Speaker Series on March 20.

In his engaging and inspiring talk, Rasmussen asked one of the most important questions in manufacturing: How do you balance innovation with sustainability while keeping a complex global supply chain running smoothly? He emphasized that success in modern manufacturing isn’t just about cutting costs — it’s about creating value across the entire network, and integrating every aspect of the business.

Successful manufacturing is all about balance

The way the toy industry views success is evolving, Rasmussen said. In the past, focusing on “cost, quality, safety, delivery, and service” may have been enough, but today’s landscape is far more demanding. “Now, it’s about availability, customers’ happiness, and innovation,” he said.

Rasmussen, who has been with the LEGO Group since 2001, started as a buyer before moving to various leadership roles within the organization. Today, he oversees the LEGO Group’s operations strategy, including manufacturing and supply chain planning, quality, engineering, and sales and operations planning.

“The way we can inspire the builders of tomorrow is basically, whatever we develop, we are able to produce, and we are able to sell,” he said.

The LEGO Group’s operations are intricate. Focusing on areas such as capacity and infrastructure, network utilization, analysis and design, and sustainability, keeps the company true to its mission, “to inspire and develop the builders of tomorrow.” Within the organization, departments operate with a focus on how their decisions will impact the rest of the company. To do this, they need to communicate effectively.

Intuition and experience play a big role in effective decision-making

In a time where data analytics is a huge part of decision-making in manufacturing and supply-chain management, Rasmussen highlighted the importance of blending data with intuition and experience.

“Many of the decisions you have to make are very, very complex,” he explained. “A lot of the data you’re going to provide me is based on history. And what happened in history is not what you’re facing right now. So, you need to really be able to take great data and blend that with your intuition and your experience to make a decision.”

This shift reflects a broader trend in industries where leaders are beginning to see the benefits of looking beyond purely data-driven decision-making. With global supply chains disrupted by unforeseen events like the Covid-19 pandemic, there’s growing acknowledgement that historical data may not be the most effective way to predict the future. Rasmussen said that the audience should practice blending their own intuition and experience with data by asking themselves: “Does it make sense? Does it feel right?”

Prioritizing sustainability 

Rasmussen also highlighted the LEGO Group’s ambitious sustainability goals, signaling that innovation cannot come at the expense of environmental responsibility. “There is no excuse for us to not leave a better planet for the next generation, for the next hundred years,” he said.

With an ambition to make its products from more renewable or recycled materials by 2032 and eliminate single-use packaging, the company aims to lead a shift in trends in manufacturing toward being more environmentally friendly, including an effort to turn waste into bricks.

Innovation doesn’t exist in a vacuum

Throughout his talk, Rasmussen underscored the importance of innovation. The only way to stay on top is to be constantly thinking of new ideas, he said.

“Are you daring to put new products into the market?” he asked, adding that it’s not enough to come up with a novel product or approach. How its implementation will work within the system is essential, too. “Our challenge that you need to help me with,” he said to the audience, “is how can we bring in innovation, because we can’t stand still either. We also need to be fit for the future … that is actually one of our bigger challenges.”

He reminded the audience that innovation is not a linear path. It involves risk, some failure, and continuous evolution. “Resilience is absolutely key,” he said.

Q&A

After his presentation, Rasmussen sat down with Professor John Hart for a brief Q&A, followed by audience questions. Among the questions that Hart asked Rasmussen was how he would respond to a designer who presented a model of MIT-themed LEGO set, assuring Rasmussen it would break sales records. “Oh, I’ve heard that so many times,” Rasmussen laughed.

Hart asked what it would take to turn an idea into reality. “How long does it take from bricks to having it on my doorstep?” he asked.

“Typically, a new product takes between 12 to 18 months from idea to when we put it out on the market,” said Rasmussen, explaining that the process requires a good deal of integration and that there is a lot of planning to make sure that new ideas can be implemented across the organization.

Then the microphone was opened up to the crowd. The first audience questions came from Emerson Linville-Engler, the youngest audience member at just 5 years old, who wanted to know what the most difficult LEGO set to make was (the Technic round connector pieces), as well as Rasmussen’s favorite LEGO set (complex builds, like buildings or Technic models).

Other questions showcased how much LEGO inspired the audience. One member asked Rasmussen if it ever got old being told that he worked for a company that inspires the inner child? “No. It motivates me every single day when you meet them,” he said.

Through the Q&A, the audience was also able to ask more about the manufacturing process from ideas to execution, as well as whether Rasmussen was threatened by imitators (he welcomes healthy competition, but not direct copycats), and whether the LEGO Group plans on bringing back some old favorites (they are discussing whether to bring back old sets, but there are no set plans to do so at this time).

For the aspiring manufacturing leaders and innovators in the room, the lesson of Rasmussen’s talk was clear: Success isn’t just about making the right decision, it’s about understanding the entire system, having the courage to innovate, and being resilient enough to navigate unexpected challenges.

The event was hosted by the Manufacturing@MIT Working Group as part of the Manufacturing@MIT Distinguished Speaker Series. Past speakers include the TSMC founder Morris Chang, Office of Science and Technology Policy Director Arati Prabhakar, Under Secretary of Defense for Research and Engineering Heidi Shyu, and Pennsylvania Governor Tom Wolf.
