Are you an introvert or an extrovert? Your face can visibly answer this question, a Carnegie Mellon University professor argues.
Douglas Hofstadter, the Pulitzer Prize–winning author of Gödel, Escher, Bach, thinks we've lost sight of what artificial intelligence really means. His stubborn quest to replicate the human mind.
Motivated Numeracy and Enlightened Self-Government. "Why does public conflict over societal risks persist in the face of compelling and widely accessible scientific evidence? We conducted an experiment to probe two alternative answers: the “Science Comprehension Thesis” (SCT), which identifies defects in the public’s knowledge and reasoning capacities as the source of such controversies; and the “Identity-protective Cognition Thesis” (ICT) which treats cultural conflict as disabling the faculties that members of the public use to make sense of decision-relevant science.

Researchers at MIT's Department of Brain and Cognitive Sciences have identified two "morality centers" of the brain. In two separate experiments, they have shown a correlation between a particular part of the brain and the ability to make moral jusgments related to intent to commit a crime. In one experiment, patients with brain damage in the ventromedial prefrontal cortex of the brain don't consider hypothetical perpetrators to be morally responsible for their actions. In another experiment (noted on NPR today) the researchers showed that they could switch off the moral judgment function by applying a magnetic field to the right temporoparietal junction (TPJ) of the brain. The TPJ has also been implicated in "out of body experiences", both in cases of brain damage and by artificially stimulating the area.
"Over and over he scoops up a chick with his left hand, expels its droppings with a squeeze of his thumb, opens its vent with his fingers, peers through the magnifying lenses attached to his spectacles and determines its sex." It's a dirty job (YT). Sexing chicks early is important so that the cockerels can be separated and culled^ or fed to be broilers^. The obvious differences take weeks to develop, so when the vent sexing method was developed in Japan in the 1920s, professional chicken sexers became sought after. [more inside]
