Cannabidiol (CBD( products are being illegally marketed for pets, including a product for use in the eye, and for various conditions in humans also, despite any evidence they can prevent, diagnose, mitigate, treat or cure various diseases. Shady hucksters have sought to avoid that by preying on the margins of what are known as “supplements” and exempt from science and logic thanks to President Clinton's Dietary Supplement Health and Education Act of 1994, which declared open season on medicine by legitimizing alternatives with no evidence.

A deficiency in Vitamin D on the mother's side could explain why Autism Spectrum Disorder diagnoses are three times more common in boys, but don't start buying supplements. This was in rats and rats are not little people, there is a lot of ground to cover before this has human relevance.

A recent computer model finds that it doesn't hurt a product to negative reviews and it may even help.

A flawless product does not exist, people are suspicious if they see no bad reviews, and using game theory, the researchers analyzed how negative reviews affect sales. The model had two sets of participants: sellers, who know the true quality of the products they are selling and can selectively publish reviews about it, and buyers, who do not know a product's quality and can be categorized as either 'naïve' or 'rational'.

There is no question that masks prevent transmission of airbone viruses that cause diseases flu and COVID-19 but a new paper shows what will maximize their effectiveness.

Masks are primarily intended to keep us from spreading germs - a surgeon does not wear a mask because she is worried about her patient giving her a disease, she is wearing it to make the other person safer.

This winter solstice, Dec. 21st, you'll be able to see something no one has seen since the Middle Ages; Jupiter and Saturn will appear so close together in Earth’s night sky they will look like a double planet.

While we orbit the sun each year, Jupiter needs 12 and Saturn 30, which means every 20 years or so Jupiter laps Saturn, and on December 21st, 2020, the two planets will be just a tenth of a degree apart, less than the diameter of the moon. The two largest planets in our solar system will look to some like a double planet from science fiction. 

A new meta-analysis finds what scientists outside the U.S. Food and Drug Administration and National Center for Complementary and Integrative Health have long known - alternatives to medicine, now called Integrative Medicine after failing as Complementary and Alternative Medicine after failing as Traditional Medicine after failing as Folk Medicine, are not just useless, they are ecologically reckless.
