Down syndrome symposium highlights clinical, fundamental progress

December 4, 2020

Whether they are working with patients in clinical trials or with chromosomes in cell cultures, scientists and physicians in the Boston area and beyond are testing a wide variety of new ways help people with Down syndrome. At the New England Down Syndrome Symposium, presented by the Alana Down Syndrome Center on Nov. 10, a virtual audience of hundreds of people learned about the research progress of a dozen research teams. The Alana Center at MIT partnered with the...

Twenty years of cultivating tech entrepreneurs

December 4, 2020

In 2010, Clarisse Iribagiza was studying computer engineering at the University of Rwanda’s College of Science and Technology. She was intrigued to hear about a program on the fundamentals of technological entrepreneurship offered by the MIT Global Startup Labs (GSL) at her college. “I had never heard of startups, but I wanted to understand what they were about,” she says. Soon after finishing a six-week GSL stint, Iribagiza, a junior, launched a mobile technology company, HeHe Limited, which became...

Lincoln Laboratory is designing a payload to...

December 3, 2020

According to Space-Track.org, approximately 21,000 objects of human origin are orbiting Earth, and about 1,500 of these objects are in or near geosynchronous orbit (GEO). Satellites in GEO support critical services, including commercial and military communications, weather forecasting, and missile launch warnings. The number of satellites and debris objects in the GEO belt is growing as launch rates increase and more countries gain access to space. These sensors will support the comprehensive space domain awareness (SDA) tracking efforts that...

Focusing on innovative solutions to the world’s...

December 3, 2020

Like many things in 2020, the annual MIT EnergyHack hosted by the MIT Energy Club looked very different this year. For the first time since its founding six years ago, MIT EnergyHack was run as an all-virtual event. The organizing team did not take this as a setback, and instead embraced the opportunity to reach out to a wider audience than ever before, inviting hackers from all over the world to participate. Guided by principles of engagement, impact, and...

Illustrating Covid-19 hygiene best practices

December 3, 2020

Cartoons and illustrations have long been used to convey important health and safety messages. From emergency manuals on airplanes to posters in hotel rooms depicting what to do in case of a fire, they can communicate life-saving information in clear and simple terms that are universally understood. An international multidisciplinary team of volunteers known as TeamOSV-X has been utilizing this medium to demonstrate health, hygiene, and safety best practices related to Covid-19. They have released open-source educational posters and...

Indigenous knowledge and technology at MIT: “Is...

December 3, 2020

In November, 10 Indigenous media scholars and artists convened at MIT — virtually — for the inaugural Indigenous Digital Delegation. In a week-long series of gatherings, the delegation met with over 60 MIT scientists, staff, fellows, and students. The theme of the gathering was “Indigenous Knowledge, Artificial Intelligence, and Digital Worlds.” “Wisdom is not a topic that is taught or studied in the curriculum in our schools or universities, nor is it a practice in modern life,” said Ojibwe...

Physicists capture the sound of a “perfect”...

December 3, 2020

For some, the sound of a “perfect flow” might be the gentle lapping of a forest brook or perhaps the tinkling of water poured from a pitcher. For physicists, a perfect flow is more specific, referring to a fluid that flows with the smallest amount of friction, or viscosity, allowed by the laws of quantum mechanics. Such perfectly fluid behavior is rare in nature, but it is thought to occur in the cores of neutron stars and in the...

Neuroscientists find a way to make object-recognition...

December 3, 2020

Computer vision models known as convolutional neural networks can be trained to recognize objects nearly as accurately as humans do. However, these models have one significant flaw: Very small changes to an image, which would be nearly imperceptible to a human viewer, can trick them into making egregious errors such as classifying a cat as a tree. A team of neuroscientists from MIT, Harvard University, and IBM have developed a way to alleviate this vulnerability, by adding to these...

Letter from President Reif: Commitments to our...

December 3, 2020

The following letter was sent to the MIT community Dec. 3 by President L. Rafael Reif. To the members of the MIT community, Last January, following the release of a fact-finding report about Jeffrey Epstein’s ties to MIT, I articulated five actions to address the challenges that emerged during that difficult time. I write with updates on those actions. Please know that MIT offers extensive resources for survivors. I encourage you to use any you might find helpful. We...

New microscope technique reveals details of droplet...

December 2, 2020

Nucleation is a ubiquitous phenomenon that governs the formation of both droplets and bubbles in systems used for condensation, desalination, water splitting, crystal growth, and many other important industrial processes. Now, for the first time, a new microscopy technique developed at MIT and elsewhere allows the process to be observed directly in detail, which could facilitate the design of improved, more efficient surfaces for a variety of such processes. The innovation uses conventional scanning electron microscope equipment but adds...

MIT opens childcare center in Graduate Tower...

December 2, 2020

On Nov. 9, the Institute welcomed some of its youngest students to the new MIT Technology Childcare Center (TCC) Kendall in the Graduate Tower at Site 4 (Building E37), in accordance with Massachusetts’ Department of Early Education and Care and Department of Public Health regulations and safety protocols. Located at 45 Hayward Street, the approximately 8,000-square-foot, state-of-the-art facility is designed to serve 58 toddler and preschool children. TCC Kendall’s infant classroom will remain in the Koch Biology Building (Building...

This 3D printer doesn’t gloss over the...

December 2, 2020

Shape, color, and gloss. Those are an object’s three most salient visual features. Currently, 3D printers can reproduce shape and color reasonably well. Gloss, however, remains a challenge. That’s because 3D printing hardware isn’t designed to deal with the different viscosities of the varnishes that lend surfaces a glossy or matte look. MIT researcher Michael Foshey and his colleagues may have a solution. They’ve developed a combined hardware and software printing system that uses off-the-shelf varnishes to finish objects...

3 Questions: Hessam AzariJafari on mitigating climate...

December 1, 2020

Extreme heat events — like those seen in California in 2020 — are expected to worsen over the century due to climate change and urban heat islands (UHIs). Cities will likely experience the brunt of those effects. To help cities mitigate UHI and extreme heat, MIT Concrete Sustainability Hub postdoc Hessam AzariJafari is studying one of the most abundant urban surfaces: pavements. He has found that it’s possible to significantly lower urban air temperatures and greenhouse gas emissions by...

Study examines role of mobile health technology...

December 1, 2020

A 60-person task force, including MIT Lincoln Laboratory researchers, has published a study reviewing mobile health (mHealth) technologies and examining their use in monitoring and mitigating the effects of the Covid-19 pandemic. They found that mHealth technologies are viable options to monitor Covid-19 patients and predict symptom escalation for earlier intervention. The study, “Can mHealth Technology Help Mitigate the Effects of the COVID 19 Pandemic?”, is published in the IEEE Open Journal of Engineering in Medicine and Biology. The...

Sensing the body at all scales

December 1, 2020

Sensors that track everything from infection in the lungs to WiFi usage on a busy university campus are poised to enhance our understanding of, and approach to improving, human health at many levels — a trend that has been accelerated by the challenges of the Covid-19 pandemic, researchers and experts said at the 2020 SENSE.nano Symposium. Videos from the event are now available online, so anyone can view the presentations and panel discussions featuring leaders from research and industry,...
