Covid-19

Popular Mechanics reporter Courtney Linder spotlights how Prof. Alfredo Alexander-Katz is developing a “rapid antigen Covid-19 test that can accurately detect viral proteins in just minutes.”

Marc Zissman, associate division head at Lincoln Lab, speaks with New York Times reporter Jennifer Valentino-DeVries about the challenges associated with encouraging people to use coronavirus tracing apps.

Prof. Justin Reich speaks with NPR’s Anya Kamenetz about digital teaching during the Covid-19 pandemic and how children and teachers are adjusting to the new experience. "There's [approximately] 10% of people for whom it works better," Reich says. And for these students, "this is actually a better version of school."

MIT researchers have developed a model that could help people estimate the risks of contracting Covid-19 in different scenarios, reports Emily Czachor for Newsweek. The tool “provides calculations which estimate how many people can remain within an enclosed space, and for how long, before they are theoretically exposed to the virus.”

Research scientist Brian Subirana speaks with The Economist’s Babbage podcast about his work developing a new AI system that could be used to help diagnose people asymptomatic Covid-19.

Writing for WBUR, Prof. Kate Kellogg and alumna Noa Ghersin outline how to help prevent outbreaks of Covid-19 at long-term care facilities. “Nursing homes lack the resources of other institutions,” they write. “They aren’t states, they aren’t cities, they aren’t major hospital systems.”

MIT researchers have developed a new model that could be used to help determine “how long you will be safe in a room with someone who is positive for COVID-19 based on room type, size and even the ventilation and filtration system,” reports Boston 25 News.

MIT researchers have discovered the molecular structure of a protein that plays a key role in the coronavirus’ ability to replicate itself and stimulate the host cell’s inflammation response, reports Travis Anderson for The Boston Globe. “If researchers can find a way to ‘block this channel,’” writes Anderson, “then they might be able to reduce the ‘pathogenicity of the virus’ and also obstruct viral replication.”

Fast Company reporter Mark Sullivan writes that Prof. John Bush and Prof. Martin Z. Bazant have developed a mathematical model that “simulates the fluid dynamics of virus-loaded respiratory droplets in any space, from a cozy kitchen to a gigantic concert hall.”

A new study by MIT researchers finds that “changes in coronavirus levels in wastewater preceded rises and falls in positive test results by four to 10 days,” reports Kim Tingley for The New York Times. The findings suggest that “sewage surveillance could play an important role in helping contain the pandemic.”

Smithsonian reporter Rasha Aridi writes that MIT researchers have found that longing for social interaction elicits a similar neurological response to a hungry person craving food. The researchers found that “after a day of fasting, they noted that they were uncomfortable and had intense food cravings. After social isolation, they felt lonely and unhappy and yearned for interactions.”

A new study by MIT researchers finds that lack of social contact can lead many people to crave interactions in a similar manner as they do when experiencing hunger, reports Katherine Dunn for Fortune. The researchers found that “10 hours without any social contact, for many people, led to a kind of psychological and physical craving that's on the same level of intensity as 10 waking hours without food.”

MIT researchers have uncovered evidence that humans crave social contact in the same way they crave food, reports Ali Pattillo for Inverse. The study, “provides empirical support for the idea that loneliness acts as a signal – just like hunger – that signals to an individual that something is lacking and that it needs to take action to repair that," explains former MIT postdoc Livia Tomova.

Fast Company reporter Adele Peters spotlights Particles for Humanity, an MIT spinoff that is developing a new technology that makes it possible to deliver multiple doses of a vaccine in one shot. “The new technology works like traditional drug delivery,” writes Peters, “but with the addition of tiny time-release capsules filled with antigens, the part of the vaccine that stimulates the immune system so that it can later respond to a virus.”

Prof. Eric Alm speaks with New York Times Magazine reporter Kim Tingley about how studying wastewater can provide public health officials with advance warning of an uptick in coronavirus cases. “If you want to really understand what’s going on in a city on a basic chemical, biological level, you should be looking at the wastewater," says Alm.
