Unlocking the secrets of a plastic-eater

June 8, 2020

It was during a cruise in Alaska that Linda Zhong realized that the world didn’t have to be full of plastic. “I grew up in cities, so you’re very used to seeing all kinds of trash everywhere,” says the graduate student in microbiology. Zhong, who is Canadian and lived in Ottawa growing up and in Toronto during college, routinely saw trash in the waters of the Ottawa River and on the beaches around Lake Ontario. “You never see it...

Professor Emeritus Michael Athans, pioneer in control...

June 8, 2020

MIT electrical engineering and computer science Professor Emeritus Michael Athans died peacefully on May 26 at his home in Clearwater, Florida, at the age of 83. Athans was born in Drama, Macedonia, Greece in 1937. He came to the United States in 1954 for a one-year exchange visit under the auspices of the American Field Service (AFS), and attended the Tamalpais High School in Mill Valley, California. His year in the AFS was a defining one. He fell in...

Research highlights immune molecule’s complex role in...

June 8, 2020

More than a decade before people with Huntington’s disease (HD) show symptoms, they can exhibit abnormally high levels of an immune-system molecule called interleukin-6 (IL-6), which has led many researchers to suspect IL-6 of promoting the eventual neurological devastation associated with the genetic condition. A new investigation by MIT neuroscientists shows that the story likely isn’t so simple. In a recent study they found that Huntington’s model mice bred to lack IL-6 showed exacerbated symptoms compared to HD mice...

Engineers put tens of thousands of artificial...

June 8, 2020

MIT engineers have designed a “brain-on-a-chip,” smaller than a piece of confetti, that is made from tens of thousands of artificial brain synapses known as memristors — silicon-based components that mimic the information-transmitting synapses in the human brain. The researchers borrowed from principles of metallurgy to fabricate each memristor from alloys of silver and copper, along with silicon. When they ran the chip through several visual tasks, the chip was able to “remember” stored images and reproduce them many...

Transparent graphene electrodes might lead to new...

June 5, 2020

A new way of making large sheets of high-quality, atomically thin graphene could lead to ultra-lightweight, flexible solar cells, and to new classes of light-emitting devices and other thin-film electronics. The new manufacturing process, which was developed at MIT and should be relatively easy to scale up for industrial production, involves an intermediate “buffer” layer of material that is key to the technique’s success. The buffer allows the ultrathin graphene sheet, less than a nanometer (billionth of a meter)...

MIT startup wraps food in silk for...

June 5, 2020

Benedetto Marelli, assistant professor of civil and environmental engineering at MIT, was a postdoc at Tufts University’s Omenetto Lab when he stumbled upon a novel use for silk. Preparing for a lab-wide cooking competition whose one requirement was to incorporate silk into each dish, Marelli accidentally left a silk-dipped strawberry on his bench: “I came back almost one week later, and the strawberries that were coated were still edible. The ones that were not coated with silk were completely...

If transistors can’t get smaller, then coders...

June 5, 2020

In 1965, Intel co-founder Gordon Moore predicted that the number of transistors that could fit on a computer chip would grow exponentially — and they did, doubling about every two years. For half a century, Moore’s Law has endured: Computers have gotten smaller, faster, cheaper, and more efficient, enabling the rapid worldwide adoption of PCs, smartphones, high-speed internet, and more. This miniaturization trend has led to silicon chips today that have almost unimaginably small circuitry. Transistors, the tiny switches...

Taking an MIT approach to a return...

June 5, 2020

As MIT continues to consider and refine options for the fall, two questions stand out: how to safely and responsibly welcome people back into the Institute’s physical spaces, and how to ensure the MIT community can excel and thrive during what will likely be an extended and ongoing pandemic. While several groups work to answer those questions, MIT has also begun to collect data to inform a return to campus. A residence hall study launched earlier this spring has...

MIT Logarhythms host a virtual concert and...

June 4, 2020

In the wake of the Covid-19 pandemic, the MIT Logarhythms did not miss a beat in finding new ways to stay connected, make music, and engage with the MIT community. Instead of on-campus a cappella rehearsals or concerts, the Logs took their show online. “We pretty quickly as a group got into the mindset that this is an opportunity to exercise a lot of creative freedom … and to try a lot of new things, because the circumstances are...

Controlling plasma and plasma turbulence

June 4, 2020

“What are some challenges in controlling plasma and what are your solutions? What is the most effective type of fusion device? What are some difficulties in sustaining fusion conditions? What are some obstacles to receiving fusion funding?” For the past four years, graduate student Norman Cao ’15 PhD ’20 has been the Plasma Science and Fusion Center’s (PSFC’s) go-to “answer man,” replying to questions like these emailed by students and members of the general public interested in getting a...

Recent political science graduates see brighter days...

June 4, 2020

Blindsided by a pandemic and hunkering down at home instead of celebrating spring on campus, MIT seniors might reasonably have felt blue. But a group of new political science alumni glimpse brighter days ahead, as they springboard from rewarding academic programs into meaningful careers. “I feel prepared for the life in policy work I have been planning, one that’s focused on energy and climate mitigation,” says Michelle Bai ’20, a double major in economics and political science with a...

Peatland drainage in Southeast Asia adds to...

June 4, 2020

In less than three decades, most of Southeast Asia’s peatlands have been wholly or partially deforested, drained, and dried out. This has released carbon that accumulated over thousands of years from dead plant matter, and has led to rampant wildfires that spew air pollution and greenhouse gases into the atmosphere. The startling prevalence of such rapid destruction of the peatlands, and their resulting subsidence, is revealed in a new satellite-based study conducted by researchers at MIT and in Singapore...

Town halls let students “Solve for Fall”

June 3, 2020

On May 13, student leaders, heads of house, and the MIT Division of Student Life (DSL) hosted two separate town halls — one for graduate students and one for undergraduates — to engage the student community in identifying and implementing possible solutions to the complex community problem posed by Covid-19. As organizers wrote in their May 4 invitation to students, “We need to ensure that whatever approach we take for the fall, we prioritize and protect community health and...

In online vigil, MIT community shares grief,...

June 3, 2020

“We are suffering from a multigenerational fracture,” rising junior and Undergraduate Association President Danielle Geathers said yesterday, referring to centuries of racism in America. “The bone was never set, and healing never occurred. Today we see the latest inflammation of that initial injury.” Geathers spoke at an online MIT community vigil held in response to the killing of George Floyd and the loss of other black lives due to racism and police brutality, and to the wave of protests...

Associate Professor Amah Edoh receives Baker Award...

June 3, 2020

Amah Edoh, associate professor in anthropology, has received the Everett Moore Baker Award for Excellence in Undergraduate Teaching. This Institute-wide award, named in honor of Everett Moore Baker, dean of students from 1947 to 1950, is given every year to an MIT faculty member, recognizing an “exceptional interest and ability in the instruction of undergraduates.” As the prize parameters specify, “this is the only teaching award in which the nomination and selection of the recipients is done entirely by...
