Special thanks to my daughter Karen for her guidance with QR codes!

Here is what I am reading today:

“Some of the human X chromosome originates from Neanderthals and is found exclusively in people outside Africa, according to an international team of researchers led by Damian Labuda of the Department of Pediatrics at the University of Montreal and the CHU Sainte-Justine Research Center. The research was published in the July issue of Molecular Biology and Evolution.”

“A new study of the brain’s master circadian clock — known as the suprachiasmatic nucleus, or SCN — reveals that a key pattern of rhythmic neural activity begins to decline by middle age. The study, whose senior author is UCLA Chancellor Gene Block, may have implications for the large number of older people who have difficulty sleeping and adjusting to time changes.”

“Is your kid a “dove” — cautious and submissive when confronting new environments, or perhaps you have a “hawk” — bold and assertive in unfamiliar settings?”

“Cost and Value. A majority of Americans (57%) say the higher education system in the United States fails to provide students with good value for the money they and their families spend. An even larger majority (75%) says college is too expensive for most Americans to afford. At the same time, however, an overwhelming majority of college graduates (86%) say that college has been a good investment for them personally.”
