Having neural machinery dedicated to face processing suggests that this ability is hard-wired in dogs through cognitive evolution, and may help explain dogs' extreme sensitivity to human social cues.
Climate change caused by greenhouse gas emissions will alter the way that Americans heat and cool their homes. By the end of this century, the number of days each year that heating and air conditioning are used will decrease in the Northern states, as winters get warmer, and increase in Southern states, as summers get hotter, according to a new study from a high school student, Yana Petri, working with Carnegie's Ken Caldeira.
Researchers at the University of Birmingham, UK and the University of Neuchatel, Switzerland, have found that wild bonobos, our closest living relatives in the primate world, communicate in a similar manner to human infants, using a high-pitched call type, or 'peep,' that requires context to be understood.
From an early age, human infants are able to produce vocalizations in a wide range of emotional states and situations -- an ability felt to be one of the factors required for the development of language. Researchers have found that wild bonobos (our closest living relatives) are able to vocalize in a similar manner. Their findings challenge how we think about the evolution of communication and potentially move the dividing line between humans and other apes.
As Hurricane Guillermo continued moving toward the Hawaiian Islands, NASA's RapidScat instrument that flies aboard the International Space Station analyzed its surface winds.
Typhoon Soudelor grew into a Super typhoon today, Aug. 3, 2015, as the GPM core satellite passed overhead and determined where the heaviest rainfall was occurring in the powerful storm.
Scientist Elena Belova of the US Department of Energy's Princeton Plasma Physics Laboratory and a team of collaborators have proposed an explanation for why the hot plasma within fusion facilities called tokamaks sometimes fails to reach the required temperature, even as researchers pump beams of fast-moving neutral atoms into the plasma in an effort to make it hotter.

A new analysis of early hominin body size evolution led by a George Washington University professor suggests that the earliest members of the Homo genus (which includes our species, Homo sapiens) may not have been larger than earlier hominin species.
Researchers at Princeton University have for the first time directly calculated the rate at which water crystallizes into ice in a realistic computer model of water molecules. Understanding ice formation adds to our knowledge of how cold temperatures affect both living and non-living systems, including how living cells respond to cold and how ice forms in clouds at high altitudes.
