Attention to the Unseen

O’Brian, University at Buffalo, The State University of New York Several high-profile papers on COVID-19 research have come under fire from people in the scientific community in recent weeks. Two articles addressing the safety of certain drugs when taken by COVID-19 patients were retracted, and researchers are calling for the retraction of a third paper that evaluated behaviors that mitigate coronavirus…

CNN reports: Spain’s large-scale study on the coronavirus indicates just 5% of its population has developed antibodies, strengthening evidence that a so-called herd immunity to Covid-19 is “unachievable,” the medical journal the Lancet reported on Monday. The findings show that 95% of Spain’s population remains susceptible to the virus. Herd immunity is achieved when enough of a population has become infected with a virus or bacteria — or vaccinated against it — to stop its circulation. The European Center for…

The New York Times reports: The coronavirus is finding new victims worldwide, in bars and restaurants, offices, markets and casinos, giving rise to frightening clusters of infection that increasingly confirm what many scientists have been saying for months: The virus lingers in the air indoors, infecting those nearby. If airborne transmission is a significant factor in the pandemic, especially in crowded spaces with poor ventilation, the consequences for containment will be significant. Masks may be needed indoors, even in socially-distant…

Zeynep Tufekci writes: We’ve entered another risky, uncertain phase of America’s pandemic summer. COVID-19 cases are surging across most states, and once again, intensive-care units are filling up. Eighteen states have either paused or rolled back their plans to reopen, and even Republican governors who previously resisted public-health guidelines about masks are now asking people to mask up. So why on Earth do so many articles about this crisis feature pictures of people frolicking on wide-open beaches? Why is an…

If they are too virulent, they kill or incapacitate their hosts; this limits their ability to infect new hosts. Conversely, viruses that cause little harm may not be generating enough copies of themselves to be infectious. But SARS-CoV-2, the coronavirus that causes…

Breathing in through the nose is an integral part of meditation and delivers virus-fighting gases to the lungs. triloks / Getty Images By Louis J. Ignarro, University of California, Los Angeles Inhale through your nose and exhale through your mouth. It’s not just something you do in yoga class – breathing this way actually provides a powerful medical benefit that can help the body fight viral infections. The reason is that your nasal cavities produce the molecule nitric oxide, which…

The New York Times reports: It’s a question that has haunted scientists since the pandemic began: Does everyone infected with the virus produce antibodies — and if so, how long do they last? Not very long, suggests a new study published Thursday in Nature Medicine. Antibodies — protective proteins made in response to an infection — may last only two to three months, especially in people who never showed symptoms while they were infected. The conclusion does not necessarily mean…

Reports show that the mortality rate among men with COVID-19 is higher than women. Marco Mantovani/Getty Images By Adam Moeser, Michigan State University When it comes to surviving critical cases of COVID-19, it appears that men draw the short straw. Initial reports from China revealed the early evidence of increased male mortality associated with COVID. According to the Global Health 50/50 research initiative, nearly every country is now reporting significantly higher COVID-19-related mortality rates in males than in females as…

The New York Times reports: When Linsey Marr’s son started attending day care 12 years ago, she noticed that he kept getting sick with the sniffles and other minor illnesses. But unlike most parents, Dr. Marr, an aerosol scientist at Virginia Tech, tried to figure out why. “When I’d pick him up, I’d find out that more than half the kids in the room were sick too,” said Dr. Marr. “I was really curious, and wondered, if it was spreading…

The Wall Street Journal reports: Six months into the coronavirus crisis, there’s a growing consensus about a central question: How do people become infected? It’s not common to contract Covid-19 from a contaminated surface, scientists say. And fleeting encounters with people outdoors are unlikely to spread the coronavirus. Instead, the major culprit is close-up, person-to-person interactions for extended periods. Crowded events, poorly ventilated areas and places where people are talking loudly—or singing, in one famous case—maximize the risk. These emerging…

Vox reports: At first, Lauren Nichols tried to explain away her symptoms. In early March, the healthy 32-year-old felt an intense burning sensation, like acid reflux, when she breathed. Embarrassed, she didn’t initially seek medical care. When her shortness of breath kept getting worse, her doctor tested her for Covid-19. Her results came back positive. But for Nichols, that was just the beginning. Over the next eight weeks, she developed wide and varied symptoms, including extreme and chronic fatigue, diarrhea,…
