The microbiome is the collection of microorganisms in an environment and plays an important role in human health. An imbalance of 'good' microbes compared to 'bad' is linked to adverse health outcomes. A person's gut microbiome with a higher number of different bacterial species is considered a marker of gut health but no one is really sure what that means.

If marijuana has analgesic properties, people will try it to potentially manage their pain, but it is unclear if it does or not. Fortunately, the U.S. Drug Enforcement Administration signaled it is expanding its marijuana research program will draft guidelines for producing the drug for scientific and medical research. 

Until there are science answers it is people trying all of the above, and that creates confounders for other kinds of research. A new study says adults who take prescription opioids for severe pain are more likely to have increased anxiety, depression and substance abuse issues if they also use marijuana. But did marijuana cause the depression or is it being used to mitigate it? 

The ketogenic diet is a high fat, low carbohydrate diet that has become a health fad but it was originally posited as a benefit for people with epilepsy.

Exercise is obviously physically beneficial and there are claims it also releases happiness-inducing hormones - and it may work that way for a few but if you are suffering from depression the last thing you need is someone in a Live Love Laugh shirt asking if you tried going for a walk.

In America, more women than men receive Ph.D.s and at the faculty level are not 2:1 more likely to be offered a job. Not so in France. Only 35 percent of researchers at the French National Centre for Scientific Research are women and the reason may be bias in French culture. 

In France, the concept of science remains much more strongly associated with masculinity than with femininity and it may lead to scientific evaluation committees putting women at a disadvantage during promotion rounds involving men and women researchers, say social science scholars.

If you read the Anglo-Saxon history of England, the island was a backwater savage place populated by sacrificial druids worshiping angry spiritual gods before Rome paved the way for the arrival of modern inhabitants, but that me just be invading victors writing history.

It has been assumed northwestern European trade during the Bronze Age was primarily socially embedded, as in the exchange of gifts.  It turns out people in England, before the invasions by Celts, Picts, Irish, Angles, Saxons, Romans, Vikings, and Normans, were using balance weights and scales to measure the value of materials as early as the late second and early first millennia BC.
