Everything is a Brand

The environmental toll of disposable masks

July 20, 2021

Since the Covid-19 pandemic began last year, face masks and other personal protective equipment have become essential for health care workers. Disposable N95 masks have been in especially high demand to help prevent the spread of SARS-CoV-2, the virus that causes Covid-19. All of those masks carry both financial and environmental costs. The Covid-19 pandemic is estimated to generate up to 7,200 tons of medical waste every day, much of which is disposable masks. And even as the pandemic...

With the HUMANS project, a message that...

July 20, 2021

When the Voyager 1 and Voyager 2 spacecraft launched in 1977, they each carried a Golden Record, a special project spearheaded by astrophysicist Carl Sagan, in addition to the scientific instruments necessary for their mission to explore the outer reaches of our solar system. Part time capsule, part symbolic ambassador of goodwill, the Golden Record comprises sounds, images, music, and greetings in 59 languages, providing a snapshot of life on Earth for the edification of any intelligent extraterrestrial beings...

Enhancing drug delivery with ultrasound

July 20, 2021

It can be difficult to get drugs to disease sites along the gastrointestinal tract, which spans the mouth, esophagus, stomach, small and large intestine, and anus. Invasive treatments can take hours as patients wait for adequate amounts of drugs to be absorbed at the right location. The same problem is holding back newer treatments like gene-altering therapies. Now the MIT spinout Suono Bio is advancing a new approach that uses ultrasound to deliver drugs, including nucleic acids like DNA...

Making it through a pandemic senior year...

July 19, 2021

Miles Johnson graduated this June with degrees in mathematics and electrical engineering and computer science, and a minor in physics. But if he could add another concentration to his degree, then Johnson would add pandemic survival, which he passed with flying colors thanks to solid friendships formed during his time at MIT. At San Francisco University High School, Johnson relied on a support network of teachers, program leaders, and friends that made it easy to push himself. Later, as...

Contact-aware robot design

July 19, 2021

Adequate biomimicry in robotics necessitates a delicate balance between design and control, an integral part of making our machines more like us. Advanced dexterity in humans is wrapped up in a long evolutionary tale of how our fists of fury evolved to accomplish complex tasks. With machines, designing a new robotic manipulator could mean long, manual iteration cycles of designing, fabricating, and evaluating guided by human intuition. Most robotic hands are designed for general purposes, as it’s very tedious...

MIT.nano receives American Institute of Architects’s Top...

July 16, 2021

MIT.nano, MIT’s open-access facility for nanoscale science and engineering, has been awarded the American Institute of Architects (AIA) 2021 Committee on the Environment (COTE) Top Ten Award for excellence in sustainability and design. The annual award recognizes 10 projects, located anywhere in the world, that meet AIA’s Framework for Design Excellence — 10 principles aimed at creating a zero-carbon, equitable, resilient, and healthy built environment. Projects are evaluated on how well they are designed for integration, equitable communities, ecosystems,...

MIT Schwarzman College of Computing awards named...

July 16, 2021

The MIT Stephen A. Schwarzman College of Computing has awarded two inaugural chaired appointments to Dina Katabi and Aleksander Madry in the Department of Electrical Engineering and Computer Science (EECS). “These distinguished endowed professorships recognize the extraordinary achievements of our faculty and future potential of their academic careers,” says Daniel Huttenlocher, dean of the MIT Schwarzman College of Computing and the Henry Ellis Warren Professor of Electrical Engineering and Computer Science. “I’m delighted to make these appointments and acknowledge...

A noninvasive test to detect cancer cells...

July 15, 2021

Most of the tests that doctors use to diagnose cancer — such as mammography, colonoscopy, and CT scans — are based on imaging. More recently, researchers have also developed molecular diagnostics that can detect specific cancer-associated molecules that circulate in bodily fluids like blood or urine. MIT engineers have now created a new diagnostic nanoparticle that combines both of these features: It can reveal the presence of cancerous proteins through a urine test, and it functions as an imaging...

Getting dressed with help from robots

July 14, 2021

Basic safety needs in the paleolithic era have largely evolved with the onset of the industrial and cognitive revolutions. We interact a little less with raw materials, and interface a little more with machines. Robots don’t have the same hardwired behavioral awareness and control, so secure collaboration with humans requires methodical planning and coordination. You can likely assume your friend can fill up your morning coffee cup without spilling on you, but for a robot, this seemingly simple task...

3 Questions: James Poterba on making infrastructure...

July 14, 2021

With a timeframe resembling that of a construction project, the U.S. Congress is working on an infrastructure bill. How effective could the legislation be? In a new paper, James M. Poterba, the Mitsui Professor of Economics at MIT, and co-author Edward Glaeser, an economist at Harvard University, survey economic aspects of infrastructure investment in the U.S. They advocate for cost-benefit analyses of projects, find that repairing infrastructure often pays off more than new projects, and suggest that infrastructure user...

How aspirations become actions

July 14, 2021

Minutes before finding out he’d been accepted to MIT, Mussie Demisse ’21 was shaking Governor Charlie Baker’s hand. Demisse was at an awards ceremony at the Massachusetts State House, being honored as one of the 2018 “29 Who Shine,” a select group of graduates from the Commonwealth’s higher education system who’d made an impact at their institution and in the community. For Demisse, Bunker Hill Community College, where he’d spent the previous two years studying computer science, represented both....

Restoring amputees’ natural functionality with brain-controlled interfaces

July 13, 2021

When someone close to rising MIT junior Eeshan Tripathii and his sister, engineer Vini Tripathii, had their hand amputated, the siblings witnessed the challenges of living with a prosthetic. After a year of arguing with insurance companies to get their loved one a top-of-the-line prosthetic, they were dismayed that it failed to bring the loved one closer to the functionality needed for an independent life. The device itself had strong mechanical dexterity. In practice, though, it was difficult to...

3 Questions: Richard Milner on the messier...

July 13, 2021

“The Hermes Experiment,” a new book by MIT physics Professor Richard Milner and FAU Erlangen-Nurnberg Professor Erhard Steffens, tells the story of how several hundred physicists from Europe and North America collaborated in 1988 to design, construct, and operate the innovative HERMES experiment at the DESY laboratory in Hamburg, Germany, with the goal of studying the fundamental spin structure of matter. The book serves as a primer on subatomic physics and provides a personal look into how physics gets done,...

Software to accelerate R&D

July 13, 2021

Many scientists and researchers still rely on Excel spreadsheets and lab notebooks to manage data from their experiments. That can work for single experiments, but companies tend to make decisions based on data from multiple experiments, some of which may take place at different labs, with slightly different parameters, and even in different countries. The situation often requires scientists to leave the lab bench to spend time gathering and merging data from various experiments. Teams of scientists may also...

3 Questions: Secretary Kathleen Theoharides on climate...

July 12, 2021

Massachusetts is poised to be a national and global leader in the fight against climate change. This spring, Kathleen Theoharides, secretary of the Executive Office of Energy and Environmental Affairs of the Commonwealth of Massachusetts, spoke with MIT Energy Initiative Director Robert Armstrong at a seminar focused on Massachusetts’ emissions-reduction plans. Here, Theoharides discusses the state’s initiatives to address the decarbonization of key sectors to help the state achieve these goals. Q: In March, Massachusetts Governor Charlie Baker signed...
