A Brain Made of Memristors
In 1997 the then world chess champion Garry Kasparov faced off with the IBM supercomputer, Deep Blue. Kasparov had defeated the computer five times, and he was ready to show the world once again that intelligent thought was still the sole province of human beings. But this match was different. After three drawn games and one win each, Deep Blue crushed Kasparov in the sixth game. The Artificial Intelligence (AI) community declared a victory: finally, man’s champion had been outmatched by the intelligence of a machine.
Alzheimer’s Disease Vaccine on the Horizon
Alzheimer’s disease (AD) is a devastating illness that causes memory loss and intellectual impairment. AD currently afflicts an estimated 18 million people throughout the world, but it affects countless more friends, caregivers, and relatives. More than 1 in 13 people over the age of 65 have signs and symptoms consistent with AD. Unfortunately, the cause of AD is still unclear a century after its discovery, and the disease is largely untreatable.
Brain Development and College Football
Most of us have experienced the thrills and agonies of watching our chosen sports teams either perform well or poorly. During college football season in the United States, millions of fans devote their weekends to watching people run up and down fields while trying to avoid getting too injured. Those who follow college football notice that there are not many freshman players who are starting quarterbacks. Why is this? Other than the generally obvious fact that most teams already have quarterbacks who are farther along in their schooling, another reason why there are not many starting freshman quarterbacks is not as obvious.
Are Rhesus Monkeys Self-Aware?
Conventional wisdom from cognitive science posits that a variety of animals can recognize themselves in the mirror and, therefore, possess self-awareness. Traditionally, macaque monkeys have not been included among them, but a new study utilizing refined behavioral methods reveals that rhesus monkeys can indeed recognize themselves in the mirror. The results appear to reconcile a decades-old conundrum about presumably variable self-recognition abilities among evolutionarily distinct primates.
