Here is what I am reading today:
“When Yanomamö men in the Amazon raided villages and killed decades ago, they formed alliances with men in other villages rather than just with close kin like chimpanzees do. And the spoils of war came from marrying their allies’ sisters and daughters, rather than taking their victims’ land and women.”
“Ever wonder how biologists use RNA sequencing from cytoplasm to decode a cell’s stress response? Or how about how astronomers use heterodyne arrays with superconducting mixers to observe the birth of stars? Rather than reading a paper about it, why not watch a dance? A ballet and a modern dance on those very topics have made it into the finals of this year’s “Dance Your Ph.D.” contest.
It was a tight race among this year’s 21 Ph.D. dance submissions. The previous winners of the contest scored each of them on their scientific and artistic merits, and these 12 finalists made the cut.”
“The study involved a small group of healthy people aged in their late 20s to early 30s who rode exercise bikes. They were monitored for changes in the brain immediately after the exercise and again 15 minutes later.
“We saw positive changes in the brain straight away, and these improvements were sustained 15 minutes after the exercise had ended,” says research leader Associate Professor Michael Ridding.”
“Using a high-resolution, one-of-a-kind microscope, Daniel A. Dombeck and Mark E. J. Sheffield peered into the brain of a living animal and saw exactly what was happening in individual neurons called place cells as the animal navigated a virtual reality maze.”
““Dopamine is a ubiquitous molecule in the brain that signals ‘mission accomplished.’ It serves as the key indicator during almost all aspects of learning and the formation of new memories,” said David Kleinfeld professor of physics at UC San Diego, who directed the work. “Disruptions to dopamine signaling lie at the heart of schizophrenia and addiction.” Kleinfeld also holds appointments in neurobiology, and electrical and computer engineering.”
“Richard G. M. Morris developed the water maze that bears his name as an alternative for the radial arm maze. The radial arm maze had been used for many decades prior to Morris’s first use of the water maze in 1981.
The radial arm maze provides limited information about cues other than the immediate visual environment. Because Morris was interested in an array of cues, including audition and olfaction, he needed to find another way to study spatial learning.
“Dr Shelley Gorman, of the Telethon Kids Institute and lead author of the study, said: “Our findings are important as they suggest that casual skin exposure to sunlight, together with plenty of exercise and a healthy diet, may help prevent the development of obesity in children.”
“These observations further indicate that the amounts of nitric oxide released from the skin may have beneficial effects not only on heart and blood vessels but also on the way our body regulates metabolism,” Dr Martin Feelisch, Professor of Experimental Medicine and Integrative Biology at the University of Southampton, added.”
John Cacioppo and I have worked hard to update our text to reflect the many discoveries that have affected the wonderfully dynamic field we call Psychology! Questions?? feel free to contact me: laura (AT) laurafreberg.com
