InsideTracker - a personalized-nutrition company founded by scientists from MIT, Harvard, and Tufts University - utilizes blood tests to calculate biological age, reports Betsy Morris for The Wall Street Journal. The company analyzes blood samples for “markers of conditions like inflammation, heart health and liver or kidney disorder,” explains Morris. “Those who test as older than their years get recommendations to adjust diet, exercise and supplements.”
Researchers at MIT and Harvard Medical School have created an artificial intelligence program that can accurately identify a patient’s race based off medical images, reports Tony Ho Tran for The Daily Beast. “The reason we decided to release this paper is to draw attention to the importance of evaluating, auditing, and regulating medical AI,” explains Principal Research Scientist Leo Anthony Celi.
During the AI Cures Conference, Prof. Regina Barzilay spoke with Food and Drug Administration senior staff fellow Amir Khan about how the agency intends to regulate artificial intelligence in medicine, reports Casey Ross for STAT. “’My thinking is that models should be regulated based on their functionality, and not necessarily on the input data they use,” said Barzilay.
J-PAL research manager Jesse Gubb writes for STAT about how voluntary innovation tests can lead to providers favoring profitable programs over what is best for patients and can make potential reforms harder to evaluate. “The Center for Medicare and Medicaid Innovation is in the rare position of being empowered to develop innovative payment models and prospectively evaluate them,” writes Gubb. “Mandatory, national randomized evaluations ensure that the already significant effort to develop the models will yield the rigorous evidence needed to support decisions on whether to scale and adopt them broadly.”
STAT reporter Katie Palmer spotlights Principal Research Scientist Leo Anthony Celi’s research underscoring the importance of improving the diversity of datasets used to design and test clinical AI systems. “The biggest concern now is that the algorithms that we’re building are only going to benefit the population that’s contributing to the dataset,” says Celi. “And none of that will have any value to those who carry the biggest burden of disease in this country, or in the world.”
Boston Globe reporter Michael Blanding spotlights Prof. Hugh Herr’s work with Dr. Matthew Carty in developing a new amputation surgery called agonist-antagonist myoneural interface (AMI) procedure, which reconnects muscles to amplify electrical signals sent along the nerves. “My dream as a scientist is that a person with an arm amputation could play a Beethoven piece at normal speeds and dexterity – and for legs, that a person could dance ballet,” says Herr.
Professor Linda Griffith speaks with Radio Boston host Tiziana Dearing about her research on endometriosis. The dream is “that we get diagnosis at the start, and you get your therapy at the start, and you don’t even develop the disease,” says Griffith.
Researchers from MIT and journalists from STAT conducted a months long investigation and found that “subtle shifts in data fed into popular health care algorithms — used to warn caregivers of impending medical crises — can cause their accuracy to plummet over time, raising the prospect AI could do more harm than good in many hospitals,” reports Casey Ross for STAT.
PBS Nova premiered “Augmented,” a documentary film that features Prof. Hugh Herr and his research team’s work in developing brain controlled robotic limbs and reimagining amputation procedures. “Herr is teaming up with an injured climber and a surgeon at a leading Boston hospital to test a new approach to surgical amputation that allows prosthetic limbs to move and feel like the real thing,” writes PBS Nova.
Wall Street Journal reporter John Anderson spotlights “Augmented” a new PBS documentary featuring Prof. Hugh Herr and his work in robotic limbs and surgery.
A new documentary titled “Augmented” spotlights Prof. Hugh Herr and his work developing bionic limbs at the MIT Media Lab, reports Dana Gerber for The Boston Globe. “The long-term hope for the procedure is that people with Ewing amputations will be able to further adapt to the bionic limbs shown in the film, which Herr’s team is developing at MIT,” writes Gerber.
Dr. Warren Zapol ’62, an anesthesiologist at Massachusetts General Hospital who made breakthroughs in studying the impact of inhaled nitric oxide, died on Dec. 14, 2021, at the age of 79, reports Bryan Marquard for The Boston Globe. “Warren’s discovery and demonstration that nitric oxide is a highly effective therapy for pulmonary hypertension in newborns and in adults is one of the most significant achievements in recent intensive care medicine history,” says Prof. Emery N. Brown, director of the Harvard-MIT Health Sciences and Technology program.
STAT reporters Katie Palmer and Casey Ross spotlight how Prof. Regina Barzilay has developed an AI tool called Mirai that can identify early signs of breast cancer from mammograms. “Mirai’s predictions were rolled into a screening tool called Tempo, which resulted in earlier detection compared to a standard annual screening,” writes Palmer and Ross.
Salon reporter Elizabeth Landau spotlights the work of researchers from MIT and the Massachusetts Eye and Ear Infirmary in uncovering how Covid-19 can affect the ear. Viruses such as Covid-19, “all have these tentacles that seem to touch the ear, but nobody’s been able to study them because the ear is so inaccessible,” says Prof. Lee Gehrke. “So that’s the part that I think I get most excited about. Now we have a way to look at these things in a way that we were not able to do before.”
MIT researchers are developing innovations aimed at improving Covid-19 diagnostics, including an atomic-level test designed to increase testing accuracy, reports Steven Zeitchik for The Washington Post. Professor James Collins and his team are developing “a mask that uses freeze-dried technology to detect the coronavirus.”
