COVID-19 makes us reconsider so many of our normal activities. Sure, driving is the safest from the perspective of COVID-19 exposure. Planes, perhaps not as safe, as corporations and your wallet determine the seating relative to other travelers. But what about trains? Let's take a look.
There is a distinction between healthy concern for the coronavirus and deeply unhealthy obsession and paranoia. Guess which side Esquire magazine picked?
"Twelve Diseases That Changed Our World" was originally published in 2007 but has taken on renewed relevance during the COVID-19 pandemic. Will the coronavirus similarly change our world? We review the book authored by Prof. Irwin Sherman.
Hip fractures remain a significant health problem, especially for the elderly, where a fracture can lead to immobility and a downward spiral. Making use of data from the Framingham Osteoporosis Study, a new study looks at the risk factors and incidence of hip fractures over the last several decades. The study focused on recognized risk factors for fracture, in the end singling out two: smoking and drinking. 
Can you personalize public health guidance? One-size-fits-all policy, in the era of COVID, is causing a great deal of controversy. Are the feds, the states, or local officials best equipped in deciding what measures to put in place? A new study provides a more local, county-wide view.
Long ago, roughly 100 years past, in a place far away, there were few (if any) effective treatments for pneumonia. One treatment that seemed to help was targeting the lungs with low-dose radiation. Could COVID-19’s attack on the lungs be stopped in a similar way? Several small studies are now underway to find out.
“You can think of the human immune system as an orchestra playing together and needing a co-ordinated performance from all the musicians and their instruments. It doesn’t make scientific sense to talk about antibodies or T-cells on their own.”
The foundation of medical research, which is considered the gold standard, is the Randomized Controlled Trial when individuals are matched with others, and then randomized to one treatment or another. While the beauty of an RCT lies in its process of deliberate randomness, very little attention has been paid to the integrity of its building blocks: categories. It's time to take a more in-depth look.
A new study paints a counter-intuitive picture of COVID-19’s viral load. Or does it?
The risk to students of reopening schools is quite small. For instance, more young adults aged 15-24 will drown than die from coronavirus. The challenge for re-opening schools is the risk posed to teachers, staff, and students' families.
As Spock and the other Vulcans say, Live long and prosper. But what actually can we do, according to our best current science, to achieve that healthy lifespan?
As we continue to try and “open up,” much is made of herd immunity. Herd immunity was the putative, underlying rationale for some countries to forgo quarantine and lockdowns. But what exactly do we mean when we talk about herd immunity?
