What is something we can do to fight against COVID-19 and improve indoor air quality for human health? Portable high efficiency particle air (HEPA) cleaners and masking can significantly reduce exposure to SARS-CoV-2 aerosol particles. Continue reading Portable HEPA Cleaners and Masking can Reduce Exposure to SARS-CoV-2 Aerosols
by Edward Chen Historical evidence shows that developing safe vaccines is necessary to protect the world from deadly diseases. But that’s only one part of the solution. After all, what’s the benefit of having vaccines that people don’t want to use? Enter vaccine hesitancy. Defined by a World Health Organization (WHO) working group as a “delay in acceptance or refusal of vaccination despite availability of … Continue reading Vaccine hesitancy: More than a pandemic
by Edward Chen The COVID-19 pandemic has catalyzed rapid technological advancements as scientists and engineers mobilize to combat its toll on human lives. Time is of the essence, and after rigorous testing for safety and effectiveness, there are now 3 vaccines with emergency approval in the United States that are all based on relatively new concepts. Two of the vaccines are based on messenger RNA … Continue reading How do COVID-19 vaccines work? Hear from a researcher who helped develop the Johnson & Johnson vaccine.
by Aleks Procherafigures by Shreya Mantri The past year and a half have been a time of profound uncertainty. We all wish we could gaze into a COVID crystal ball and get answers to our burning questions. Some of us would want to know how long the pandemic will last. Others, however, especially those who have never received a positive result, would likely seek an … Continue reading It’s Not All about Microbes: Genetics and susceptibility to infections
by Sophia Swartzfigures by Shreya Mantri The first reports of a mysterious, pneumonia-like illness surfaced in early December 2019. Fast-forward to 2021, and the culprit—SARS-CoV-2, a virus a thousand times smaller than a speck of dust—has sickened more than 111 million people, infected all seven continents, and killed approximately 2.5 million. The toll of COVID-19 is heart-wrenching and borders on dystopian. Our pandemic present is … Continue reading Mutation Madness: How and why SARS-CoV-2 keeps changing
Severe disease related to COVID-19 infection may be linked to the absence of a single sugar molecule on antibodies in patient sera samples. Continue reading Severe COVID-19 Disease Potentially Linked to a Single Missing Sugar in Antibodies
by Christopher Rotafigures by Daniel Utter The COVID-19 pandemic has touched every corner of American society, including the lives of scientists. The past year has seen many researchers dramatically shift the focus of their work, as experts from across different disciplines came together to study this novel disease and develop potential therapies. The National Institutes of Health, the United States’ foremost public biomedical research agency, … Continue reading The “Covidization” of Science: Short-Term Necessity or Problematic Over-Reaction?
by Jaclyn Long figures by Tal Scully A year into the pandemic, many people still struggle to get tested for COVID-19. By some estimates, asymptomatic transmission can account for up to 50% of all new cases, making regular testing of people who don’t yet (or might never) show symptoms a key part of a public health strategy to control the virus. Despite the effectiveness of mass … Continue reading The Challenges of Large-Scale COVID-19 Testing
by Molly Sargenfigures by Molly Sargen, Buse Aktaş, and Aparna Nathan COVID-19 is unarguably devastating from any perspective. Even as we struggle to overcome the present challenges of the pandemic, COVID-19 is paving the way for other infectious agents to cause damage in the future. Although SARS-CoV-2 is a virus that cannot be treated with antibiotics, antibiotic usage has significantly increased throughout the pandemic. With … Continue reading How COVID-19 is Shaping Antibiotic Resistance
by Piyush Nandafigures by Corena Loeb In an area devastated by deforestation, an 18-month-old toddler from the nearest settlement, Meliandou in Guinea, was seen playing around a fallen tree swarming with bats. The child then contracted a mysterious illness, which spread to many who came in contact. After it had already killed 30 people, the illness was identified as Ebola. Comprehensive studies have since connected … Continue reading Are Pandemics the Cost of Human Recklessness Towards Nature?
