Only mammals express RAGE

RAGE stands for “receptor for advanced glycation end-products”, also known as “AGER”, and new research shows that it first appeared in mammals (Sessa et al., 2014). Despite the name, the receptor also binds other signaling molecules such as HMGB1, S100 proteins, beta-amyloid, phosphatidylserine, among others (Xie et al., 2013). RAGE is reportedly involved in diabetes,…

Great White Shark Longevity

Scientists have discovered that great white sharks (Carcharodon carcharias) actually live longer than previously thought (up to 23 years or so). Using radiocarbon age estimates, Dr. Hamady and colleagues at Woods Hole Oceanographic Institution determined the animals can live to the ripe-old-age of 70+ years. These findings mean that great white sharks, like humans, may…

Photographer Graham McGeorge has captured remarkable images of bonobos, our closest living relative that share 98.7% of human DNA. The photos depict bonobos engaging in similar behaviors as humans, like the image above from another photographer of bonobos embracing each other. McGeorge also captured images of bonobos caring for their young as well as a…
