Recently, I’ve written about how fake news and deceptive publishing practices are making it difficult for consumers to distinguish fact from fiction when it comes to science.

Most people are quick to dismiss internet trolls as completely unlike themselves ― the fabled 400-pound guy sitting on his bed, for instance.


And with partisan rage taking over Twitter alongside the election of a troller in chief, it can feel like we’re living in the golden age of internet trolling: Posting inflammatory and offensive comments online for the purpose of provoking others has become a sadly common phenomenon.

Why Skipping Vaccines Is A Public, Not Personal, Health Choice

(Reuters Health) - Too many U.S. adults are not getting vaccinated, putting themselves and others at risk, immunization experts say.


According to the latest available data, about 44 percent of adults over age 19 had a flu shot; 20 percent had a TDAP vaccine, which protects against tetanus, diphtheria and pertussis; and 20 percent of 19-to-64-year-olds at risk of pneumonia had that vaccine (compared to 60 percent of those over 65).
