The types of snacks a child chooses could be linked to genetics, a new study found. The study investigated whether genetic variants in taste receptors related to sweet, fat and bitter tastes influence the snacks preschoolers choose and found nearly 80 per cent carried at least one of these genotypes that could predispose them to poor snacking habits. These findings could help parents tailor their kids' diets based on their genetics of taste.

The global fishing fleet is so big it can be seen from space. Really.

From short 'tsiks' and 'ekks' to drawn-out 'phees' -- all the sounds produced by marmoset monkeys are made up of individual syllables of fixed length, according to a new study. The smallest units of vocalization and their rhythmic production in the brain of our relatives could also have been a prerequisite of human speech.

New research overturns a long-held assumption that Przewalski's horses, native to the Eurasian steppes, are the last wild horse species on Earth.

When a complex system is left alone, it will return to its initial state with almost perfect precision. Gas particles in a container, for example, will return almost exactly to their starting positions after some time. For decades, scientists have investigated how this 'Poincaré Recurrence Theorem' can be applied to the world of quantum physics. Now, researchers have successfully demonstrated a kind of 'Poincaré recurrence' in a multi-particle quantum system.

Scientists have found the first major evidence that Neanderthals, rather than modern humans, created the world's oldest known cave paintings -- suggesting they may have had an artistic sense similar to our own.

The presence or absence of a unique brain signal after a listener has heard some speech indicates whether or not that listener has understood what has been said. The discovery has a number of practical applications, including tracking language development, assessing brain function post-injury, and confirming whether important instructions have been understood in high-pressure jobs.

Scientists have demonstrated that the new neurons produced in adults react preferentially to reward-related sensory stimuli and help speed up the association between sensory information and reward. Adult-born neurons therefore play an important role in both the identification of a sensory stimulus and the positive value associated with that sensory experience. The neurons generated shortly after birth are unable to perform this function.

With the help of airborne laser mapping technology, a team of archeologists is exploring on a larger scale than ever before the history and spread of settlement at the ancient Maya site of Ceibal in Guatemala.
