Build the Human Body by Richard Walker | Book Review | @GrrlScientist
This kit overcomes one of the main challenges for teaching anatomy by adopting a build-it-yourself approach. The book is concise, well-written and engaging and the kit is accurate and interesting and will provide many hours of enjoyment as children and adults work together to build the human body. Sometimes, the best way to learn is to wrap your hands around stuff and ... build it yourself! This perhaps is never more important than when trying to learn anatomy, which is the reason that these courses include models and a "wet lab". But what if you don't have access to squishy things that you can cut up? This is where Richar...

The sleep cycle of mammals is partly regulated by the neuropeptide orexin, which is exclusively produced in the hypothalamus and from there travels to other parts of the nervous system. Wakefulness tends to increase when orexin binds to specific receptors in the brain and brain stem... (Source: Health News from Medical News Today)

Boosting 'cellular garbage disposal' can delay the aging process, UCLA biologists report
UCLA life scientists have identified a gene previously implicated in Parkinson's disease that can delay the onset of aging and extend the healthy life span of fruit flies. The research, they say, could have important implications for aging and disease in humans. The gene, called parkin, serves at least two vital functions: It marks damaged proteins so that cells can discard them before they become toxic, and it is believed to play a key role in the removal of damaged mitochondria from cells. "Aging is a major risk factor for the development and progression of many neurodegenerative diseases," said David Walke...
