Society has encouraged people to be more physically active, yet we are actually becoming less active. This new study offers a possible explanation: Our brains may be innately attracted to sedentary behavior. Electroencephalograms showed that test subjects had to summon extra brain resources when trying to avoid physical inactivity.
Social interactions can be intricate -- and not just among humans. A new study suggests that researchers may be overlooking some of these same complexities in the social relations of our closest primate relatives, such as chimpanzees and macaques.
Termite colonies have been found to thrive and reproduce without males, new research from the University of Sydney reveals. The findings provide new evidence that males aren't required to maintain some advanced animal populations. They add momentum to questions about the impact and function of males in animal societies.
Birds' voiceboxes are in their chests instead of their throats like mammals and reptiles. Scientists aren't sure how or why birds evolved these unique voiceboxes, but a new study sheds some light on how they came about. Similarities in the windpipes of birds, crocodiles, cats, mice, and salamanders suggest that birds' weird voiceboxes might have arisen from a windpipe reinforcement. From this, scientists can learn about the sounds bird ancestors -- dinosaurs -- made.
By looking at Earth's full natural history and evolution, astronomers may have found a template for vegetation fingerprints -- borrowing from epochs of changing flora -- to determine the age of habitable exoplanets.
Researchers have given the first demonstration of crowd counting through walls using only everyday communication signals such as WiFi. The technique, which requires only a wireless transmitter and receiver outside the area of interest, could have a variety of applications, including smart energy management, retail business planning and security.
