In terms of biology, humans and the planet’s other great apes share a common branch in the tree of life. But sadly, despite their near-humanity, our primate cousins continue to die out at the hands of those who consider them as mere commodities. Continue reading

Scientists have identified the molecular system that contributes to the harmful inflammatory reaction in the brain during neurodegenerative diseases. An important aspect of chronic neurodegenerative diseases, such as Alzheimer’s, Parkinson’s, Huntington’s or prion disease, is the generation of an innate inflammatory reaction within the brain. Results from the study open new avenues for the regulation of the inflammatory reaction and provide new insights into the understanding of the biology of microglial cells, which play a leading role in the development and maintenance of this reaction. Continue reading
