Researchers from MIT and Harvard have developed a “3D-printed ‘lab-on-a-chip’ that could detect Covid-19 immunity levels and Covid infections from saliva within two hours,” reports Ben Leonard and Ruth Reader for Politico.

The Daily Beast

Researchers from MIT and other institutions have developed a postcard-sized test that can detect a Covid-19 infection and the presence of antibodies resulting from an infection, reports Maddie Bender for the Daily Beast.  “What excites me about this diagnostic device is that it combines a high level of accuracy with a flexible design that could make it a major tool in our arsenal for addressing future pandemics,” explains Prof. James Collins.

Forbes

A new study by researchers from MIT and BU finds that the “thin gold leaf material used to decorate picture frames or lamp bases could also be used to detect viral infections,” writes Eva Amsen for Forbes. The use of an accessible material like gold leaf means a diagnostic device made from the material “could be used in doctors’ offices or field clinics anywhere in the world, no matter how far they are from a hospital.”

BBC News

BBC Click spotlights a new semi-autonomous, wearable robot developed by MIT researchers that takes different types of measurements from the skin to identify conditions such as skin cancer. “The doctor can see your whole body, but the doctor doesn’t pick up the small changes in your skin conditions, which the robot can do,” says graduate student Artem Dementyev.

United Press International (UPI)

Researchers from MIT’s Little Devices Lab have developed Lego-like devices that can perform diagnostic tests, writes UPI reporter Allen Cone.  The devices could significantly reduce the cost of diagnostic tests and as they don't require refrigeration or special handling, “they could be particularly useful in the developing world.”

Los Angeles Times

Using specially engineered E. coli bacteria and electronics that fit into an ingestible pill, MIT researchers have created a device that can detect internal diseases and send wireless alerts, reports Karen Kaplan for The Los Angeles Times. The device could eliminate the need for colonoscopies, which alter “the physiology inside the intestines, potentially masking signs of disease,” explains Kaplan.

USA Today

USA Today reporter Sean Rossman writes about how MIT researchers have created an ingestible sensor that can monitor the digestive tract and send information to a smartphone or tablet about a person’s health. Rossman explains that the device, “can detect blood in the stomach, something that would otherwise require an endoscopy and sedation.”

Associated Press

MIT researchers have developed an ingestible capsule that uses genetically engineered bacteria to detect potential health problems, reports Carla Johnson for the Associated Press. The researchers hope the capsule could eventually be used to, “find signs of ulcers, inflammatory bowel disease or even colon cancer.”

Wired

Wired reporter Megan Molteni writes that a team of MIT researchers has developed an ingestible sensor that could spot gastrointestinal issues. The sensor contains, “millions of genetically engineered glowing bacteria inside a AAA-battery-sized capsule,” Molteni explains.

Boston Herald

Writing for the Boston Herald, Lindsay Kalter reports that MIT scientists have built an ingestible capsule that could allow doctors to diagnose gastrointestinal diseases without invasive procedures. Graduate student Mark Mimee explains that the device, “sets the stage for having a pill that can give you a big biochemical profile of the gut related to various diseases.”

Popular Mechanics

Popular Mechanics reporter David Grossman writes that a new ingestible medical device developed by MIT researchers could monitor the health of the human gut. Calling the project “a true team effort,” Grossman explains that it required expertise in biological engineering techniques, electronic circuit design, materials, and gastroenterology.

Fast Company

Fast Company reporter Adele Peters writes that MIT researchers have designed a kit that allows scientists to develop diagnostic tests quickly and cheaply. The kit, “uses modular blocks that can be connected in different patterns to replicate the function that would typically be built into a manufactured test for pregnancy, glucose, or an infection or other disease.”

Amy Dockser Marcus of The Wall Street Journal writes about the growing interest in using CRISPR as a diagnostic tool, which led to a collaboration between MIT Professors James Collins and Feng Zhang. The result is Sherlock, a diagnostic platform that can identify viruses “based on extremely low amounts of RNA in blood and urine samples,” explains Dockser Marcus.

HuffPost

In an article for The Huffington Post, Susan Blumenthal highlights how researchers from MIT have developed a paper-based test for diagnosing the Zika virus. Blumenthal writes that “the test consists of a paper covered with yellow dots that turns purple in the presence of the RNA of the virus.”

Boston Herald

Lindsay Kalter reports for The Boston Herald that researchers from MIT, Philips, and Boston Medical Center are developing a non-invasive way to diagnose head injuries. Kalter explains that the study is part of a new collaboration between MIT and Philips and will “use data from an ultrasound machine taking measurements of blood pressure and flow.”
