Pretend to hurt to get out of work or school? Researchers led by a UC San Diego scientist have found a way to give you a real pain. The researchers have developed a computer system that detects whether pain is faked. And it’s far more accurate than the best human observers. With more development, the system could find uses helping doctors…
Keeping track of what we reveal about ourselves each day—through email and text messages, Amazon purchases and Facebook “likes”—is hard enough. Imagine a future when Big Data has access not only to your shopping habits, but also to your DNA and other deeply personal data collected about our bodies and behavior—and about the inner workings of our proteins and cells.…
Ew, boys! A species of spider monkey has been found to live in strictly sexually segregated societies, apparently because the males attack the females if they spend too much time together. They are the first non-human primate species known to systematically separate along gender lines. Geoffroy’s spider monkeys, Ateles Geoffroyi, live in loose groups of a few dozen individuals, and anecdotal evidence…
Whether we realize it, African elephants (Loxodonta africana) are listening to us. The pachyderms can tell certain human languages apart and even determine our gender, relative age, and whether we’re a threat, according to a new study. The work illustrates how elephants can sometimes protect themselves from human actions. “It is a most remarkable finding,” says Frans de Waal, a…
Bisphenol A (BPA) is a chemical that is used in a wide variety of consumer products, such as resins used to line metal food and beverage containers, thermal paper store receipts, and dental composites. BPA exhibits hormone-like properties, and exposure of fetuses, infants, children or adults to the chemical has been shown to cause numerous abnormalities, including cancer, as well…
A new brain-imaging study of mankind’s best friend has found a striking similarity in how humans and dogs — and perhaps many other mammals — process voice and emotion. Like humans, dogs appear to possess brain systems that are devoted to making sense of vocal sounds, and are sensitive to their emotional content. These systems have not previously been described…
