Wildfire Smoke Linked to Covid-19 Cases and Deaths in the West

Wildfire Smoke Linked to Covid-19 Cases and Deaths in the West

Thousands of COVID-19 cases and deaths in California, Oregon, and Washington between March and December 2020 may be attributable to increases in fine particulate air pollution (PM2.5) from wildfire smoke, according to a new study co-authored by researchers at Harvard T.H. Chan School of Public Health. The study is the first to quantify the degree to … Continued

Prognosis: Grim

As delta surges, what can we expect if vaccination and mask-wearing rates don’t change? According to investigators who previously developed the COVID-19 Simulator — which models the trajectory of the illness in the U.S. at the state and national levels — the combination of variant’s high transmissibility, low vaccination coverage in several regions, and more relaxed … Continued

New CRISPR Device Diagnoses COVID in an Hour, Detects Variants

A team of engineers from MIT and Harvard University has developed a COVID diagnostic device with a tiny footprint but huge potential. The tabletop instrument costs around $15 to manufacture and is powered by CRISPR technology. It provides COVID results from spit samples in an hour. In their new study published in Science Advances, the … Continued

New device can diagnose Covid-19 from saliva samples

Engineers at MIT and Harvard University have designed a small tabletop device that can detect SARS-CoV-2 from a saliva sample in about an hour. In a new study, they showed that the diagnostic is just as accurate as the PCR tests now used. The device can also be used to detect specific viral mutations linked to … Continued

New test detects COVID-19 variants in your spit

With the delta variant wreaking havoc on unvaccinated populations, the ability to quickly diagnose and track emerging variants of the virus is crucial. Researchers have now created a simple, inexpensive, CRISPR-based diagnostic test that allows users to test themselves for multiple variants of the SARS-CoV-2 virus at home, using just a sample of their saliva. … Continued

The present and future of COVID variants

Last week, the Centers for Disease Control and Prevention confirmed what Harvard-affiliated physicians had reported from anecdotal and laboratory evidence: the delta variant of COVID-19 not only spreads more rapidly than other versions of the virus, it can sicken vaccinated individuals who can then spread the virus to others.

Study finds genetic risk factors for severe COVID-19 illness

A massive worldwide collaboration including researchers from Vanderbilt University Medical Center (VUMC) has identified several genetic factors associated with SARS-CoV-2 infection and severe COVID-19 illness. The findings from nearly 50,000 COVID-19 patients and 2 million uninfected controls, published July 8 in the journal Nature, could lead to new treatments and demonstrates the power of genetic studies … Continued

How COVID taught America about inequity in education

The pandemic has disrupted education nationwide, turning a spotlight on existing racial and economic disparities, and creating the potential for a lost generation. Even before the outbreak, students in vulnerable communities — particularly predominately Black, Indigenous, and other majority-minority areas — were already facing inequality in everything from resources (ranging from books to counselors) to … Continued

Assessing the Delta variant

The Delta variant of the coronavirus has been spreading rapidly throughout the U.S. and worldwide. William Hanage, associate professor of epidemiology and a faculty member of the Center for Communicable Disease Dynamics at Harvard T.H. Chan School of Public Health, discusses the threat.

Face mask can help diagnose COVID-19

A team of researchers from the Wyss Institute for Biologically Inspired Engineering at Harvard University and the Massachusetts Institute of Technology has found a way to embed synthetic biology reactions into fabrics, creating wearable biosensors that can be customized to detect pathogens and toxins and alert the wearer. The team has integrated this technology into … Continued
