Human papillomavirus is a virus that is responsible for almost all cases of cervical cancer and the HPV vaccine can prevent 70 percent of those.

A new study by University of Texas Medical Branch at Galveston researchers indicates that only about half of the girls ages 11-12, the age recommended by the Centers for Disease Control, receive the vaccine.

It's become a fad for nutritionists to claim that oranges are better than orange juice, and they list numerous reasons - from added sugar in juice to better uptake of carotenoids, flavonoids and Vitamin C in whole oranges.

But how different are they? Unless you are someone on a nutrition website selling the lifestyle and health fad of the moment, not much. It is true that some juices have more sugar but that is offset by the biological fact nutrients in orange juice seem to be easier for the body to absorb from juice than when a person consumes them from unprocessed fruit. 

And there is convenience. It is better to have a health benefit from something than no health benefit at all.

There are tens of thousands of human-made chemicals circulating today and some have been bad despite studies that didn't initially find harm, yet almost every chemical is under siege by environmental groups, and they all claim science is on their side.

Everything from bisphenol A used in plastics to neonicotinoid pesticides to glyphosate weed-killers are criticized by lawyers at environmental groups despite the science consensus. How can the public know which ones really pose threats to our health and environment and which ones are just studies designed to keep poisoning lab animals until they show an effect?

Men and women are different in lots of ways and some contend that women are more emotional and that makes a difference in others areas. A recent large-scale study focused on determining the gender-dependent relationship between emotions, memory performance and brain activity.  

The scientists found that women rate emotional images as more emotionally stimulating than men do and are more likely to remember them but there were no gender-related differences in emotional appraisal of neutral images.

When there is a market, someone will sell to it, even if it does not make much sense. So you can purchase organic pineapples and non-GMO rock salt if it makes you feel better.

In Europe, most genetically modified foods, as European politicians define them, are banned but cows eat GMO feed. The cows can't tell the difference nor have studies shown any difference in milk production or meat. Vermont passed a GMO labeling law but made sure to exempt cows so that the $300 million company run by the primary funder of the Just Label It campaign could still use milk from Vermont cows fed GMO grain in organic yogurt.

Researchers are on the verge of developing a new class of anesthetics, something that has not happened in decades, according to a study published in Anesthesiology. It is being derived thanks to a new approach to identifying compounds may lead to the next generation of anesthetics.
