Muslim terrorists and the Klu Klux Klan share one thing in common; they claim to be religious even though the ideas they promote (and in the case of the former, the actions they take) are not very nice.

The fringes get all of the attention but most religious people are not clinically insane or promoting the deaths of others in order to secure their own place in Heaven, and if you remind them of their religious principles, their attitude toward negative events change, according to a paper in the Journal of Personality and Social Psychology. 

Obesity was once only for the wealthy, then it was only for Americans and the science engine that made food cheap for all, but now globalization has made it possible for the rich and poor worldwide to be fat - which brings greater risk of suffering a heart attack, stroke and diabetes.

No one wants to eat less delicious food, but they would take a pill to shed fad and a team ed by Professor Alexander Pfeifer from the University Hospital Bonn believe they have come one step closer to that.  They have found that a signaling molecule can stimulate brown fat and burn energy from food: The body's own adenosine activates brown fat and "browns" white fat. 

Though lots of people used the expensive government health insurance portal healthcare.gov to get information on the Affordable Care Act, also called Obamacare, far fewer could successfully use it to sign up.

As the stories of its flaws mounted, larger percentages instead talked to call centers or a navigator without using the website at all. That's a win for the government, which needed to show some success after expending a great deal of political capital and taxpayer money, but not without cost. How much cost is unclear, the government has not yet disclosed how many people signed up and actually paid anything, or how many stopped when they discovered that on top of payments they now had $4,000 a year deductibles.

It seems counter-intuitive that in order to survive best as a species, not everything can live forever, but some cells in our bodies are fated to die, and a Mission Impossible-style auto-destruct program insures they do.

This elaborate cell death program, known as apoptosis, got a little more insight with a study on the evolution of caspase-8, a key cell death initiator molecule that was first identified in humans. By performing the most extensive evolutionary analysis of the Casp8 protein to date,

A recent model says it provides the first characterization of the progenitor for a hydrogen-deficient supernova. Their simulation predicts that a bright hot star, which is the binary companion to an exploding object, remains after the explosion so they secured observation time with the Hubble Space Telescope (HST) to search for such a remaining star.  

Unless you are trapped at a Larry Summers protest at Harvard in 2006, you know that male and female brains are not equal in all ways.

Another study affirms that, finding a difference when it comes to the biological response to a high-fat diet. Cedars-Sinai Diabetes and Obesity Research Institute scientist Deborah Clegg, PhD, and colleagues found that the brains of male laboratory mice exposed to the same high-fat diet as their female counterparts developed brain inflammation and heart disease that were not seen in the females.
