Here is what we are reading today:

“Want to read someone’s mind? Look at their pupils. A person about to answer “yes” to a question, especially if they are more used to answering “no,” will have more enlarged pupils than someone about to answer “no,” according to a new study.”

“”The big question is really ‘How does the brain evolve,'” said Anthony Norcia, an author of the paper and a Stanford professor (research) of psychology.

The study suggests there may be an optimal way to view natural moving objects which share fundamental properties, Clark said. By statistically modeling these properties, theoretical neuroscientist James Fitzgerald, also a lead author of the paper, was able to develop a framework to test these theories, team members said. Fitzgerald was previously a graduate student at Stanford and is now a postdoctoral fellow at Harvard University.”

“…A new study suggests an additional factor at play: the timing of the tests. Adam Chuderski reviewed 26 studies that administered measures of working memory and the Raven’s Progressive Matrices test, which is the most widely used measure of fluid reasoning.*”

“If the cilia in the cochlea of the inner ear were the size of the Eiffel Tower in Paris, a movement of only 1 cm would be enough to send a message about sound to the brain (Hedspeth, 1983).”

“”We need to identify which behaviors in certain populations increase disease risk, and keep in mind that our genetic susceptibility plays a large role in cancer risk,” says Scott Kern, M.D ., the Everett and Marjorie Kovler Professor in Pancreas Cancer Research at Johns Hopkins.”

“The mantis shrimp looks like a peacock crossed with a lobster, and it lives in equally colorful coral reefs. So it may be no surprise that the crustacean appears to use an entirely new way to detect color. Researchers report online today in Science that the animal has 12 different types of receptors in its eyes that each perceives a different wavelength. Humans and honey bees get by with just three, but they use their brains to compute the different shades.”

“”Confessing to only part of one’stransgressions is attractive to a lot of people because they expect the confession to be more believable and guilt-relieving than not confessing,” said lead author Eyal Pe’er, PhD, who ran the studies at Carnegie Mellon University and is now at Bar-Ilan University in Israel. “But our findings show just the opposite is true.””
