Bisexual women are more likely to experience poor mental health and mental distress than lesbians, according to new data gleaned from the 2007 Stonewall UK Women's Health Survey. Researchers from the London School of Hygiene&Tropical Medicine analyzed responses from 5,706 bisexual and lesbian women living in the UK aged 14 or over.

The study found bisexual women were less likely to be 'out' to friends, family and work colleagues and also less likely to be in a relationship. According to the results, bisexual women were less likely to experience sexuality-related discrimination from work, health care services, education and family than lesbians, but more likely to experience discrimination from friends.

It's not new that dwellers and cities are a little less hearty than rural cousins. There is even a hygiene hypothesis that says kids in the country get dirtier to their benefit and that wealthy, educated helicopter parenting and all those hand sanitizers and antibacterial soaps are doing more harm than good.

Allergies and numerous autoimmune diseases, such as asthma and type 1 diabetes, have become more common in the past 50 years, especially in urban environments. The belief is this is caused by urban issues like pollutants from human activities, a higher level of hygiene and the reduced biological diversity of the city living environment.

With organic food a $105 billion industry juggernaut, various groups are looking to don that health halo. Even frozen food.

If you don't think food can be "fresh" and "healthy" while still being frozen, you probably also do not believe organic food has more antioxidants and uses fewer pesticides and therefore are not the target market and you can stop reading.

Consider two tragic events that took place last week.

A small cell of Islamic terrorists attacked cartoonists at the satirical magazine Charlie Hebdo and shoppers in a Paris supermarket, killing 17 people and sparking international outcry, solidarity and support.

In a laboratory first, researchers have grown human skeletal muscle that contracts and responds just like native tissue to external stimuli such as electrical pulses, biochemical signals and pharmaceuticals. The lab-grown tissue should soon allow researchers to test new drugs and study diseases in functioning human muscle outside of the human body.

The researchers started with a small sample of human cells that had already progressed beyond stem cells but hadn't yet become muscle tissue. They expanded these "myogenic precursors" by more than a 1000-fold, and then put them into a supportive, 3-D scaffolding filled with a nourishing gel that allowed them to form aligned and functioning muscle fibers.

In late 2008, the euphoria over electing a man who specifically said he wanted to put science back in its rightful place began to fade. The president-elect, it seemed, preferred the company of UFO believers, an anti-vaccine conspiracy theorist and a guy who thought girls couldn't do math.

It is well-known that “huffing” - inhaling organic solvents or propellants to achieve a “high” - is extremely dangerous, but less well known is that newer replacement products primarily used by homosexual men, called “poppers”, actually contain harmful solvents and propellants and pose the same health risks as huffing. 

The original poppers, based on alkyl nitrites and related to the medication amyl nitrite, got the name from their glass vials that “popped”, and they have been popular among gay men due to mild psychoactive effects and relaxing of smooth muscle, used to enhance sexual experience.
