Artificial intelligence model detects asymptomatic Covid-19 infections...

October 29, 2020

Asymptomatic people who are infected with Covid-19 exhibit, by definition, no discernible physical symptoms of the disease. They are thus less likely to seek out testing for the virus, and could unknowingly spread the infection to others. But it seems those who are asymptomatic may not be entirely free of changes wrought by the virus. MIT researchers have now found that people who are asymptomatic may differ from healthy individuals in the way that they cough. These differences are...

Testing sewage to home in on Covid-19

October 28, 2020

Covid-19 is a respiratory illness that spreads when infected individuals shed the novel coronavirus (SARS-CoV-2) that causes it. While this seems to happen chiefly through close contact and respiratory droplets, evidence has mounted that the disease can also spread through airborne transmission. Distancing, masks, and improved ventilation are all critical interventions to interrupt this spread. Many suffering from Covid-19 also shed the virus in their stool. With adequate plumbing, this is an unlikely source of virus transmission — but...

Designing new mirror materials for better gravitational-wave...

October 28, 2020

Nicholas Demos, a physics graduate student, didn’t travel a conventional path to MIT. A first-generation college student, Demos didn’t have a clear trajectory in mind when he first attended California State University at Fullerton after high school. “It was kind of the path of least resistance,” Demos says. When his father passed away in the middle of his undergraduate studies, Demos left school to run the family business, Novatech Lighting Systems, which makes handheld spotlights. He ran the company...

Truncated immune system receptors may regulate cellular...

October 28, 2020

MIT Media Lab researchers have discovered that shortened versions of immunity-related protein receptors, long written off as incomplete and therefore nonfunctional, can bind with their natural counterparts on the cell membrane and may represent pathways to new medications, therapies, and bionic body parts. Although chemokine receptors with truncated structure have previously been considered biologically inconsequential, a paper published in Cell Press’s iScience journal reports that truncated versions of two such receptors, CXCR4 and CCR5, bind with their corresponding ligands and play...

AI Cures: data-driven clinical solutions for Covid-19

October 27, 2020

Modern health care has been reinvigorated by the widespread adoption of artificial intelligence. From speeding image analysis for radiology to advancing precision medicine for personalized care, AI has countless applications, but can it rise to the challenge in the fight against Covid-19? Researchers from the Abdul Latif Jameel Clinic for Machine Learning in Health (Jameel Clinic), now housed within the MIT Stephen A. Schwarzman College of Computing, say the ongoing public health crisis provides ample opportunities for leveraging AI...

Online publication examines the French stage during...

October 27, 2020

The MIT Press recently published “Databases, Revenues and Repertory: The French Stage Online, 1680-1793,” an innovative collection of original essays that explore an important initiative in the digital humanities, the Comédie-Française Registers Project (CFRP). This international online collaboration consists of high-resolution reproductions of the detailed daily box office receipts for the Comédie-Française theater troupe in Paris from 1680 to 1793, as well as visualization tools that allow users to explore the box office data. “Databases, Revenues and Repertory” takes...

Elegance in C. elegans

October 27, 2020

The naked eye can barely spot the transparent nematodes at the center of PhD student Gurrein Madan’s neuroscience research. While C. elegans worms may initially seem an unassuming test subject for a graduate student who investigates the intricacies of gut-brain signaling, many of the genes found in C. elegans have counterparts in the human brain. Gurrein’s research could yield new insights into the gut-brain relationship, which may have practical health implications for humans. Gurrein works in the lab of...

The Engine announces second round of funding...

October 27, 2020

The Engine, the venture firm founded by MIT in 2016 to support “tough tech” companies, today announced it has raised $230 million in its second round of funding, and will begin making investments in additional startups focused on conceiving and commercializing solutions to some of the world’s most pressing challenges. MIT provided $25 million in anchor funding for The Engine’s Fund I, which exceeded its original goal of raising $150 million to close at over $200 million in 2017....

Leveraging a 3D printer “defect” to create...

October 26, 2020

Sometimes 3D printers mess up. They extrude too much material, or too little, or deposit material in the wrong spot. But what if this bug could be turned into a (fashionable) feature? Introducing DefeXtiles, a tulle-like textile that MIT Media Lab graduate student Jack Forman developed by controlling a common 3D printing defect — the under-extrusion of polymer filament. Forman used a standard, inexpensive 3D printer to produce sheets and complex 3D geometries with a woven-like structure based on...

Stressed on the job? An AI teammate...

October 26, 2020

Humans have been teaming up with machines throughout history to achieve goals, be it by using simple machines to move materials or complex machines to travel in space. But advances in artificial intelligence today bring possibilities for even more sophisticated teamwork — true human-machine teams that cooperate to solve complex problems. Much of the development of these human-machine teams focuses on the machine, tackling the technology challenges of training AI algorithms to perform their role in a mission effectively....

Emery Brown wins Swartz Prize for Theoretical...

October 26, 2020

The Society for Neuroscience (SfN) announced today that it has awarded the Swartz Prize for Theoretical and Computational Neuroscience to Emery N. Brown, the Edward Hood Taplin Professor of Medical Engineering and Computational Neuroscience at MIT. Brown, a member of The Picower Institute for Learning and Memory and the Institute for Medical Engineering and Science, as well as the Warren M. Zapol Professor at Harvard Medical School, is a neuroscientist, a statistician, and a practicing anesthesiologist at Massachusetts General...

Autonomous boats could be your next ride

October 26, 2020

The feverish race to produce the shiniest, safest, speediest self-driving car has spilled over into our wheelchairs, scooters, and even golf carts. Recently, there’s been movement from land to sea, as marine autonomy stands to change the canals of our cities, with the potential to deliver goods and services and collect waste across our waterways. In an update to a five-year project from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) and the Senseable City Lab, researchers have been...

October 26, 2020

The Koch Institute for Integrative Cancer Research at MIT, a National Cancer Institute (NCI)-designated cancer center, has announced that Tyler Jacks will step down from his role as director, pending selection of his successor. “An exceptionally creative scientist and a leader of great vision, Tyler also has a rare gift for launching and managing large, complex organizations, attracting exceptional talent and inspiring philanthropic support,” says MIT President L. Rafael Reif. “We are profoundly grateful for all the ways he...

Silencing gene expression to cure complex diseases

October 26, 2020

Many people think of new medicines as bullets, and in the pharmaceutical industry, frequently used terms like “targets” and “hits” reinforce that idea. Immuneering co-founder and CEO Ben Zeskind ’03, PhD ’06 prefers a different analogy. His company, which specializes in bioinformatics and computational biology, sees many effective drugs more like noise-canceling headphones. Rather than focusing on the DNA and proteins involved in a disease, Immuneering focuses on disease-associated gene signaling and expression data. The company is trying to...
