MIT scientists have shown a simple paper-strip test can detect the flu and identify the specific strain, which could prove useful in improving outbreak response and infection care, writes Dennis Thompson for HealthDay. Jon Arizti-Sanz PhD ’24 says “being able to tease apart what strain or subtype of influenza is infecting a patient has repercussions both for treating them and public health interventions.”
Boston Globe reporter Alyssa Meyers writes that MIT researchers have observed how the flu spreads between cells in the body. “Once it’s infected a cell and has commandeered its inner workings, the virus makes copies of itself that gather into buds attached to the membrane. The buds then break free from their host and go on to infect other cells.”
In an article published by U.S. News & World Report, Robert Preidt writes that MIT researchers have identified a mechanism that helps the flu viruses evolve rapidly. “Blocking flu viruses from using the host cells' chaperones could help prevent the viruses from developing resistance to existing drugs and vaccines,” says Preidt.
MIT researchers have potentially discovered a way to prevent the flu virus from evolving to resist vaccines and treatment, reports Alyssa Meyers for The Boston Globe. The researchers are also, “testing HIV and other rapidly mutating viruses to see if inhibiting chaperones could prevent those viruses from mutating and becoming treatment-resistant.”
ABC News reporter Gillian Mohney writes that Prof. Lydia Bourouiba has captured footage of a person sneezing, showing how far sneeze droplets can travel. Bourouiba found that “large droplets tended to land within 1 to 2 meters (about 3 to 6 feet) and that small droplets could get as far as 6 to 8 meters away (19 to 26 feet).”
MIT researchers have developed a programmable vaccine that could be used to respond to disease outbreaks, reports Ben Gruber for Reuters. The vaccine harnesses “messenger RNA, a genetic material that can be programmed to fight any viral, bacterial or parasitic disease by provoking an amplified immune response.”
In this article and video, Nature reporter Corie Lok spotlights Prof Lydia Bourouiba’s work studying the fluid dynamics of coughing and sneezing. Bourouiba explains that her research combines “fluid mechanics to problems that are relevant in health and epidemiology to understand better how pathogens are transmitted.”
Tech Insider’s Chris Weller reports on a new study by MIT researchers that examines how sneezes travel and spread viruses. The findings could help researchers “predict and prevent disease spread,” Weller explains. “If they know how quickly a pathogen spreads via sneeze, then they can learn more about the risks posed by the viruses themselves.”
MIT researchers used high-speed cameras to examine how sneezes travel, reports Gillian Mohney for ABC News. The researchers found that “instead of a uniform cloud of droplets, a single sneeze would fragment in the air similar to paint being flung onto a canvas.”
Washington Post reporter Annie Gowen writes about how MIT researchers have found that India’s latest swine flu outbreak may have mutated into a more dangerous strain. The researchers found “new mutations in the protein known to make the virus more virulent.”
Professor Ram Sasisekharan and research scientist Kannan Tharakaraman have found that a strain of H1N1 influenza in India is more virulent than health authorities have indicated, writes Rishi Lyengar of Time. “They found mutations in the Indian strains in a protein called hemagglutinin, which binds with receptors on the human body’s respiratory cells,” Lyengar writes.
Laura Santhanam writes for the PBS NewsHour that MIT researchers have found that a strain of swine flu in India is more dangerous than originally thought. The researchers found that “a mutation in the new H1N1 strain allows this form of swine flu to attack an infected person’s respiratory cells more virulently.”
