A new study finds that female mice treated with a small molecule that binds to a receptor found on muscle cells speeds up energy metabolism. Sorry males, this does nothing for you.

The molecule is found in tree leaves and the female mice could indulge in high-fat foods without gaining weight or accumulating fat. 

Research has shown that a hormone called brain-derived neurotrophic factor (BDNF), which is secreted after physical exercise, controls body weight gain by eliciting signals to suppress food intake and enhance energy expenditure. Manipulation of this signaling represents a promising strategy for combating obesity; however, BDNF degrades quickly in the body.

Researchers have discovered that a network of viruses usually associated with managed honeybees pose a widespread risk to bumblebees in the wild also.

The study revealed multiple interconnected diseases that are threatening several species of bumblebee and the managed honeybee, which are essential pollinators of many agricultural crops and wild flowers.  Previously research had only identified one virus, deformed wing virus, which had most likely spilled over from managed honeybees into wild bumblebee populations, and fluctuations in wild bees were attributed to pesticides by activist groups rather than the other viruses.

Older brains are more similar to younger brains than previously thought, according to a new study. 

Certainly, brains change as we get older. People get dementia and that is linked to plaque build-up, but that is not neuronal activity, as some papers using functional magnetic resonance imaging (fMRI) have claimed. Instead, it may be due to vascular (blood vessel) changes. 

Since fMRI is frequenly used (and misused) in studies to assess aging, this could have important consequences for mainstream media's ability to promote a new theory of aging once a month.

Though people selling alternatives to science will use labels like "chemical-free", that is not really the case. Our world is entirely chemical.

'Chemical' has simply been turned into a bad word in 'if I cannot pronounce it, it must be bad' modern environmentalism catered toward wealthy elites. Are green alternatives actually less toxic? No, it turns out, and even worse is that because they claim a 'natural' basis, they are exempt from the labeling requirements of traditional products, so green consumers don't know the extent of the risk they are undertaking.

New York City professes to be tolerant, diverse and outcome-oriented in many ways - education for elites is not among them. 6 percent of 8th graders will get to go to one of 8 specialized elite schools, based on test scores and all of the racial, social and income inequality that perpetuates.
