Method offers inexpensive imaging at the scale...

March 29, 2021

Using an ordinary light microscope, MIT engineers have devised a technique for imaging biological samples with accuracy at the scale of 10 nanometers — which should enable them to image viruses and potentially even single biomolecules, the researchers say. The new technique builds on expansion microscopy, an approach that involves embedding biological samples in a hydrogel and then expanding them before imaging them with a microscope. For the latest version of the technique, the researchers developed a new type...

Supporting the Covid-19 vaccine rollout with extra-strength...

March 28, 2021

Some people are actually able to bottle their success, and Mark Kurz SM ’95 is one of the lucky few. Kurz is at the forefront of the fight against Covid-19 as a manufacturing supply chain leader at Corning, the New York-based pioneer in glass science and manufacturing technology. Corning produces Valor Glass vials, a primary mode of delivery for vaccines as part of the U.S. government’s Operation Warp Speed. In his role as director of Corning’s Pharmaceutical Technologies manufacturing...

MIT keeps a firm commitment to undergraduate...

March 26, 2021

The Institute’s commitment to financial aid will remain robust for 2021-22, increasing from last year’s announced budget of $147 million to $155.2 million. The increase will offset a 3.85 percent rise in tuition and changes in housing, dining, and other estimated costs. The net cost for an average MIT student receiving need-based aid will be $22,969. When measured in real dollars, the average cost of an MIT education for those who receive financial aid has been reduced by 32...

Controlling bubble formation on electrodes

March 26, 2021

Using electricity to split water into hydrogen and oxygen can be an effective way to produce clean-burning hydrogen fuel, with further benefits if that electricity is generated from renewable energy sources. But as water-splitting technologies improve, often using porous electrode materials to provide greater surface areas for electrochemical reactions, their efficiency is often limited by the formation of bubbles that can block or clog the reactive surfaces. Now, a study at MIT has for the first time analyzed and...

Cooling homes without warming the planet

March 26, 2021

As incomes in developing countries continue to rise, demand for air conditioners is expected to triple by 2050. The surge will multiply what is already a major source of greenhouse gas emissions: Air conditioning is currently responsible for almost 20 percent of electricity use in buildings around the world. Now the startup Transaera is working to curb those energy demands with a more efficient air conditioner that uses safer refrigerants to cool homes. The company believes its machine could...

Design could enable longer lasting, more powerful...

March 25, 2021

Lithium-ion batteries have made possible the lightweight electronic devices whose portability we now take for granted, as well as the rapid expansion of electric vehicle production. But researchers around the world are continuing to push limits to achieve ever-greater energy densities — the amount of energy that can be stored in a given mass of material — in order to improve the performance of existing devices and potentially enable new applications such as long-range drones and robots. One promising...

MIT engineers make filters from tree branches...

March 25, 2021

The interiors of nonflowering trees such as pine and ginkgo contain sapwood lined with straw-like conduits known as xylem, which draw water up through a tree’s trunk and branches. Xylem conduits are interconnected via thin membranes that act as natural sieves, filtering out bubbles from water and sap. MIT engineers have been investigating sapwood’s natural filtering ability, and have previously fabricated simple filters from peeled cross-sections of sapwood branches, demonstrating that the low-tech design effectively filters bacteria. Now, the...

Astronomers image magnetic fields at the edge...

March 24, 2021

This article is adapted from an announcement by the Event Horizon Telescope. MIT Haystack Observatory is one of the 13 stakeholder institutions that constitute the Event Horizon Telescope (EHT) collaboration, which produced the first-ever image of a black hole. The EHT revealed today a new view of the massive object at the center of the M87 galaxy: how it looks in polarized light. This is the first time astronomers have been able to measure polarization, a signature of magnetic...

3 Questions: Artificial intelligence for health care...

March 23, 2021

The potential of artificial intelligence to bring equity in health care has spurred significant research efforts. Racial, gender, and socioeconomic disparities have traditionally afflicted health care systems in ways that are difficult to detect and quantify. New AI technologies, however, are providing a platform for change. Regina Barzilay, the School of Engineering Distinguished Professor of AI and Health and faculty co-lead of AI for the MIT Jameel Clinic; Fotini Christia, professor of political science and director of the MIT Sociotechnical Systems...

MindHandHeart Community Innovation Fund supports 77 projects...

March 23, 2021

The past year has been challenging — for MIT and the world. Scattered across states, countries, and continents, MIT community members have shown remarkable resiliency and creativity in finding new ways to come together and support one another amidst adversity. Sponsored and funded by the MIT Office of the Chancellor, the MindHandHeart (MHH) Community Innovation Fund, a grant program advancing projects focused on mental health, well-being, connectedness, and racial justice, has supported a record number of 77 projects during...

Study reveals plunge in lithium-ion battery costs

March 23, 2021

The cost of the rechargeable lithium-ion batteries used for phones, laptops, and cars has fallen dramatically over the last three decades, and has been a major driver of the rapid growth of those technologies. But attempting to quantify that cost decline has produced ambiguous and conflicting results that have hampered attempts to project the technology’s future or devise useful policies and research priorities. Now, MIT researchers have carried out an exhaustive analysis of the studies that have looked at...

Providing kind networks

March 22, 2021

Undeterred by the pandemic, professors Gigliola Staffilani and Daron Acemoglu persist in ensuring their students have fulfilling graduate school experiences. The two have been honored as “Committed to Caring” for their dedicated advocacy and for connecting students with wider intellectual communities. Daron Acemoglu: Celebrating potential Daron Acemoglu is an MIT Institute Professor of Economics. His research delves into political economy, economic development and growth, human capital theory, growth theory, innovation, search theory, network economics, and learning. Recently, he has...

Transforming lives by providing safe drinking water

March 21, 2021

As a child, Susan Murcott ’90 SM ’92 saw firsthand the long-term impact that water- and food-borne illness can have on people. At age 16, her maternal grandmother contracted polio, which can be transmitted through direct contact with someone infected with the virus or, occasionally, through contaminated food and water. As a result of the illness, she was forever paralyzed from the waist down. Though Murcott didn’t know it at the time, her decades-long career focusing on clean water...

March 19, 2021

Members of the MIT engineering faculty receive many awards in recognition of their scholarship, service, and overall excellence. The School of Engineering periodically recognizes their achievements by highlighting the honors, prizes, and medals won by faculty working in our academic departments, labs, and centers. Cullen Buie of the Department of Mechanical Engineering was named an American Institute for Medical and Biological Engineering Fellow on Feb. 16. Anantha Chandrakasan of the Department of Electrical Engineering and Computer Science was named an ACM...

Exploring culture, identity, and the arts to...

March 19, 2021

Jeff Toney would like you to think differently about who’s doing the teaching at MIT. The visiting professor in the MIT Department of Linguistics and Philosophy piloted an ambitious Independent Activities Period (IAP) project, bringing together students from MIT and Wellesley College to explore the rich trove of knowledge each student already possesses as a cultural inheritance. “STEM education is rooted in a tradition of students mentored by masters and icons of their field,” says Toney, who is also...
