Electronic Screen Syndrome: Is It Real?

You may have noticed that children seem to spend a lot of time interacting with screens: cell phones, tablets, computers, and video games. You may have wondered if this is bad for them or good for them. I think the answer is “it depends.” In 2012, Victoria L. Dunckley MD was the first to describe

How You Can Really Boost Your Immune System

As fears of the new coronavirus (Covid-19) spread, alternative medicine was quick to provide false reassurance in the form of misinformation and bogus remedies. A recurring theme in complementary and alternative medicine and a common mantra of those who make questionable health claims has long been “boosting the immune system.” So much so that boosting

Water Fluoridation: Public Health, Not Poison

Fluoridation of public water sources remains controversial as a public health measure despite the strong evidence that fluoride prevents tooth decay. Public debates can become quite heated, with

Darwin’s Apostles: The Battle Continues

David Orenstein and Abby Hafer have written a delightful new book, Darwin’s Apostles: The Men Who Fought to Have Evolution Accepted, Their Times, and How the Battle Continues. Darwin published On the Origin of Species in 1859.

Starting with the Terrible Twos, when toddlers hear the word “No” on a regular basis, people don’t like to be told they can’t do something.

The government requires vaccinations for school attendance; parents complain that they should be able to make their own decisions about whether

Beware Stem Cell Clinics that Offer Untested Treatments

Stem cell treatments are all the rage. Since they’re mostly illegal in the US, patients have been going to other countries for treatment (stem cell tourism). The claims are grandiose, but the evidence to support those claims is thin gruel. What are stem cells? Embryonic stem cells are the cells in the early embryo that
