System detects errors when medication is self-administered

March 18, 2021

From swallowing pills to injecting insulin, patients frequently administer their own medication. But they don’t always get it right. Improper adherence to doctors’ orders is commonplace, accounting for thousands of deaths and billions of dollars in medical costs annually. MIT researchers have developed a system to reduce those numbers for some types of medications. The new technology pairs wireless sensing with artificial intelligence to determine when a patient is using an insulin pen or inhaler, and flags potential errors...

At MIT Energy Conference, experts zero in...

March 18, 2021

Global power generation from renewables like solar and wind continues to rise, and innovation in fields like clean hydrogen production and nuclear fusion is thriving. But translating all that progress into lower global emissions will require major changes to legacy energy systems around the world. That was the most discussed challenge among speakers at this year’s MIT Energy Conference, hosted virtually last week by the MIT Energy Club. In some cases, energy systems can be adapted to integrate new...

Letter from President Reif: Supporting our Asian...

March 18, 2021

The following letter was sent to the MIT community today by President L. Rafael Reif. To the members of the MIT community, This message is for everyone. But let me begin with a word for the thousands of members of our MIT family – undergraduates, graduate students, postdocs, staff, faculty, alumni, parents and Corporation members – who are Asian or of Asian descent: We would not be MIT without you. You are our colleagues, our students, our classmates, our...

Traveling the world for global health solutions

March 18, 2021

As a kid, Andrea Orji always loved it when her grandpa would visit from Nigeria. He would share stories about his home to teach Orji, a Texas native, about her family’s heritage. But while she and her family attended school and work, her grandpa remained at the house, frequently alone. She could tell he longed to return to the familiarity of his own country, yet he remained in order to undergo and then recover from cataract surgery. Later on,...

MIT.nano courses bring hands-on experimentation to virtual...

March 17, 2021

Every minute, a person just sitting or standing without moving sheds 100,000 particles that are 500 nanometers or larger. Is that person exercising? Now it’s 10 million particles per minute, says Jorg Scholvin, assistant director of user services for Fab.nano. That’s why users of the MIT.nano cleanroom — which is controlled to have fewer than 100 such particles per cubic foot of air — wear full-body “bunnysuits” and other specialized garments to maintain the pristine environment required for nanoscale...

How coal’s decline impacts county and school...

March 17, 2021

More extreme weather, heat waves, and inland flooding are some of the impacts that the state of Pennsylvania expects to see with a changing climate. And scientists and economists agree that, if we don’t quickly reduce the greenhouse gas pollution from fossil fuels like coal and gas that contribute to warming the planet, these impacts will only grow more costly and dangerous. Yet parts of western Pennsylvania, like many regions of the United States, rely on coal and gas...

A remedy for the spread of false...

March 17, 2021

Stopping the spread of political misinformation on social media may seem like an impossible task. But a new study co-authored by MIT scholars finds that most people who share false news stories online do so unintentionally, and that their sharing habits can be modified through reminders about accuracy. When such reminders are displayed, it can increase the gap between the percentage of true news stories and false news stories that people share online, as shown in online experiments that...

ChoKyun Rha, professor post-tenure of biomaterials sciences...

March 17, 2021

ChoKyun Rha ’62, SM ’64, SM ’66, SCD ’67, an MIT professor post-tenure and a groundbreaker in biomaterials science and engineering, died March 2 in Boston. She was 87. The first woman of Asian descent to receive tenure at MIT, Rha held four degrees from the Institute and taught at MIT for more than four decades. Her husband, MIT professor of microbiology Anthony Sinskey ScD ’67, also attended MIT, as did their two sons — Tong-ik Lee Sinskey ’79,...

The physicist and the hospital

March 17, 2021

It’s hard to say that Thomas Heldt has had just one career. He’s assisted with open heart surgery. He’s studied the physiology of human space travel. Most recently, he’s designed medical devices to help patients with brain injury. “It’s been a serendipitous path,” says Heldt, a recently tenured faculty member in MIT’s Department of Electrical Engineering and Computer Science (EECS). But there is a through line: Heldt operates at the intersection of physics and medicine, where fundamental physical principles...

Scene at MIT: Ruth Anderson, pioneer of...

March 16, 2021

Ruth Krock Anderson is a mathematician and computing pioneer who has seen a lot in her 102 years. Born in Boston in 1918, she was interested in math from an early age and earned a mathematics degree at Boston Teachers College, now part of the University of Massachusetts. Soon thereafter, Anderson was asked to join the MIT Radiation Laboratory, which made key contributions to the development of microwave radar technology during the second world war. “There are quite a...

How to prevent short-circuiting in next-gen lithium...

March 16, 2021

As researchers push the boundaries of battery design, seeking to pack ever greater amounts of power and energy into a given amount of space or weight, one of the more promising technologies being studied is lithium-ion batteries that use a solid electrolyte material between the two electrodes, rather than the typical liquid. But such batteries have been plagued by a tendency for branch-like projections of metal called dendrites to form on one of the electrodes, eventually bridging the electrolyte...

3 Questions: Task Force 2021 and the...

March 16, 2021

This is part three in a series of interviews with co-chairs of Task Force 2021 and Beyond workstreams. Parts one and two were published in recent weeks. MIT’s Task Force 2021 and Beyond has been at work for nine months, charged by President Rafael Reif with exploring “how MIT might invent a thriving new future” in a post-Covid world. The effort’s Administrative Workstream, whose charge included looking at the future of working at MIT, was co-chaired by Joe Higgins,...

Ultrasound has potential to damage coronaviruses, study...

March 16, 2021

The coronavirus’ structure is an all-too-familiar image, with its densely packed surface receptors resembling a thorny crown. These spike-like proteins latch onto healthy cells and trigger the invasion of viral RNA. While the virus’ geometry and infection strategy is generally understood, little is known about its physical integrity. A new study by researchers in MIT’s Department of Mechanical Engineering suggests that coronaviruses may be vulnerable to ultrasound vibrations, within the frequencies used in medical diagnostic imaging. Through computer simulations,...

A new goal for soccer: Improving attitudes...

March 15, 2021

Across the globe, 26 million people have been displaced from their home countries by civil war, drought, political persecution, and other crises. At the same, attitudes against refugees are hardening in many countries; a 2018 survey found that 40 percent of Kenyans have heard that refugees are a security threat, and 45 percent don’t think refugees should be allowed to freely move around the country. In a new paper in the journal Comparative Political Studies, MIT Governance Lab (GOV/LAB)...

Study predicts the oceans will start emitting...

March 15, 2021

The world’s oceans are a vast repository for gases including ozone-depleting chlorofluorocarbons, or CFCs. They absorb these gases from the atmosphere and draw them down to the deep, where they can remain sequestered for centuries and more. Marine CFCs have long been used as tracers to study ocean currents, but their impact on atmospheric concentrations was assumed to be negligible. Now, MIT researchers have found the oceanic fluxes of at least one type of CFC, known as CFC-11, do...
