Two researchers from the Polytechnic University of Catalonia (UPC) and the University of Aberdeen in the United Kingdom have shown for the first time that the law of brevity in human language, according to which the most frequently-used words tend to be the shortest, also extends to other animal species. The scientists have shown that dolphins are more likely to make simpler movements at the water surface."Patterns of dolphin behavior at the surface obey the same law of brevity as human...

When if comes to pain, doctors and patients may not be speaking the same language, and a U.S. researcher says he wants to change that. David Cella of Northwestern University Feinberg School of Medicine in Chicago says he is on mission to revolutionize the language of pain, as well as fatigue, depression and anxiety. These symptoms are used by researchers to measure whether a medical treatment improves the quality of life for a patient with a chronic disease, Cella says. The glitch is that...

The discovery of a new primate fossil in Myanmar (formerly Burma) lends weight to the hypothesis that the common ancestor of humans, monkeys and apes (anthropoid primates) originated in Asia, and not in Africa. To support the hypothesis, an international team of paleontologists, including two French researchers, has shown that these primates, which are 37 million years old and named Ganlea megacanina, had an ability observed today in modern monkeys, but not in lemurs: they pried open and ate...

One of the aims imposed by the European Union in 2004 is to reduce the number of traffic accidents. However, despite the measures taken by the different administrations and the consequent decrease in the number of accidents, the results for 2010 are not close to those set by Europe. Gerardo Reveriego, a young researcher of the University of Málaga, has designed software that informs drivers of the risk situations s/he has while driving. This allows drivers to self-assess themselves and...
