Rewriting the operating manual

November 30, 2021

Suppose you were designing a system to allocate organ donations for the greater good. From one perspective, an optimized program might give organs to the youngest possible recipient, to maximize the number of life-years gained from each organ donation. However, such a system would likely be regarded as discriminatory based on its use of age, and would be unlikely to gain society-wide approval. “That’s not going to be acceptable in practice,” says Nikos Trichakis, an associate professor at the...

Ronald Kurtz, philanthropist and MIT Corporation life...

November 29, 2021

Ronald Kurtz ’54, ’59, SM ’60, a materials manufacturer with a great love of art, died on Nov. 20. He was 89. Kurtz earned three degrees at MIT — a bachelor’s degree in industrial management and bachelor’s and master’s degrees in metallurgy — all of which contributed to his keen interest in art and his extensive involvement with the Institute. “I will remember him for his profound commitment to forging strong ties between art, science, and technology,” says Philip...

Featured video: A musical encore for a...

November 29, 2021

Play video When MIT’s Hayden Library was originally dedicated in 1950, Czech-born composer Bohuslav Martinů was commissioned to write his “Piano Trio in D Minor” to mark the occasion. The piece received its world premiere in a performance by MIT professors Klaus Liepmann on violin and Gregory Tucker on piano, and George Finckel of Bennington College on cello. Seventy-one years later, the MIT Libraries celebrated the renovation of Hayden Library as a trio of current graduate students performed a...

Timber or steel? Study helps builders reduce...

November 29, 2021

Buildings are a big contributor to global warming, not just in their ongoing operations but in the materials used in their construction. Truss structures — those crisscross arrays of diagonal struts used throughout modern construction, in everything from antenna towers to support beams for large buildings — are typically made of steel or wood or a combination of both. But little quantitative research has been done on how to pick the right materials to minimize these structures’ contribution global...

Provost Martin Schmidt named president of Rensselaer...

November 23, 2021

MIT Provost Martin Schmidt has been named as the 19th president of Rensselaer Polytechnic Institute, the nation’s oldest technological research university. Schmidt, who earned his BS in electrical engineering at RPI in 1981, will assume its presidency on July 1, 2022. He has spent more than 40 years at MIT as a student, faculty member, and administrative leader. “MIT has been a remarkable home for me,” Schmidt says. “It has allowed me to pursue my research and teaching passions,...

Peeking into a chrysalis, videos reveal growth...

If you brush against the wings of a butterfly, you will likely come away with a fine sprinkling of powder. This lepidopteran dust is made up of tiny microscopic scales, hundreds of thousands of which paper a butterfly’s wings like shingles on a wafer-thin roof. The structure and arrangement of these scales give a butterfly its color and shimmer, and help shield the insect from the elements. Now, MIT engineers have captured the intricate choreography of butterfly scales forming...

Getting quantum dots to stop blinking

November 22, 2021

Quantum dots, discovered in the 1990s, have a wide range of applications and are perhaps best known for producing vivid colors in some high-end televisions. But for some potential uses, such as tracking biochemical pathways of a drug as it interacts with living cells, progress has been hampered by one seemingly uncontrollable characteristic: a tendency to blink off at random intervals. That doesn’t matter when the dots are used in the aggregate, as in TV screens, but for precision...

In MIT visit, Dropbox CEO Drew Houston...

November 22, 2021

When the cloud storage firm Dropbox decided to shut down its offices with the outbreak of the Covid-19 pandemic, co-founder and CEO Drew Houston ’05 had to send the company’s nearly 3,000 employees home and tell them they were not coming back to work anytime soon. “It felt like I was announcing a snow day or something.” In the early days of the pandemic, Houston says that Dropbox reacted as many others did to ensure that employees were safe and...

The reasons behind lithium-ion batteries’ rapid cost...

November 22, 2021

Lithium-ion batteries, those marvels of lightweight power that have made possible today’s age of handheld electronics and electric vehicles, have plunged in cost since their introduction three decades ago at a rate similar to the drop in solar panel prices, as documented by a study published last March. But what brought about such an astonishing cost decline, of about 97 percent? Some of the researchers behind that earlier study have now analyzed what accounted for the extraordinary savings. They...

Design’s new frontier

November 19, 2021

In the 1960s, the advent of computer-aided design (CAD) sparked a revolution in design. For his PhD thesis in 1963, MIT Professor Ivan Sutherland developed Sketchpad, a game-changing software program that enabled users to draw, move, and resize shapes on a computer. Over the course of the next few decades, CAD software reshaped how everything from consumer products to buildings and airplanes were designed. “CAD was part of the first wave in computing in design. The ability of researchers...

A stealthy way to combat tumors

November 19, 2021

Under the right circumstances, the body’s T cells can detect and destroy cancer cells. However, in most cancer patients, T cells become disarmed once they enter the environment surrounding a tumor. Scientists are now trying to find ways to help treat patients by jumpstarting those lackluster T cells. Much of the research in this field, known as cancer immunotherapy, has focused on finding ways to stimulate those T cells directly. MIT researchers have now uncovered a possible new way...

3 Questions: Supporting graduate student families

November 18, 2021

When you have a family, life becomes a balancing act of supporting your loved ones while managing your personal responsibilities. At MIT, three offices play a pivotal role in supporting graduate students with families — their partners, their children — as they create that balance. Naomi Carton serves as associate dean for graduate residential education (GRE), supporting the entire graduate residential community through programming, leadership, and opportunities such as Family Housing’s tailored opportunities for their residents. In the Office...

Pushing the limits of electronic circuits

November 18, 2021

Ruonan Han’s research is driving up the speeds of microelectronic circuits to enable new applications in communications, sensing, and security. Han, an associate professor who recently earned tenured in MIT’s Department of Electrical Engineering and Computer Science, focuses on producing semiconductors that operate efficiently at very high frequencies in an effort to bridge what is known as the “terahertz gap.” The terahertz region of the electromagnetic spectrum, which lies between microwaves and infrared light, has largely eluded researchers because...

Q&A: John Harbison on his new album,...

November 18, 2021

Attention, music fans: The new John Harbison album has dropped. The Nov. 2 release, titled “Diotima,” features three ambitious pieces from the repertoire of Harbison, the acclaimed composer and Institute Professor at MIT — who The New York Times once called “one of the finest American composers” of his generation, for his “willingness to transcend” prevailing conventions. Two of the works on “Diotima” have never been recorded before: the title track, written for a full orchestra and premiered by...

3 Questions: Sophie Gibert on ethics in...

November 17, 2021

Sophie Gibert is a PhD candidate in philosophy and assistant director of 24.133 (Experiential Ethics), an MIT class in which students explore ethical questions related to their internships, research, or other experiential learning activities. Gibert, who also serves as a graduate teaching fellow for Embedded EthiCS at Harvard University, which focuses on ethics for computer scientists, was formerly a predoctoral fellow in the Clinical Center Department of Bioethics at the National Institutes of Health (NIH). At MIT, her research...
