Scientists link ‘hunger hormone’ to memory in Alzheimer’s study
Scientists at The University of Texas at Dallas have found evidence suggesting that resistance to the “hunger hormone” ghrelin in the brain is linked to the cognitive impairments and memory loss associated with Alzheimer’s disease (AD). The findings, based on…
Corals take control of nitrogen recycling
Corals are shown to recycle their own waste ammonium using a surprising source of glucose–a finding that reveals more about the relationship between corals and their symbiotic algae. Symbiosis between corals and algae provides the backbone for building coral reefs,…

Body representation in monkeys’ brains
A study explores the neuropsychological basis for body representation in monkeys. A sense of ownership of one’s own body is a central element of self-consciousness. The psychological and neurological mechanisms underlying this sense can be investigated through illusions, such as…
Iris and sclera coloration in great apes
Researchers compared how gray-scale values of sclerae contrasted with iris coloration in 51 bonobos, 50 chimpanzees, and 52 humans, and found that sclerae are lighter than irises in bonobos and humans, whereas in chimpanzees sclerae are darker than irises, suggesting…
