Look at what i'm saying: Engineers show brain depends on vision to hear Posted: 04 Sep 2013 05:35 PM PDT Bioengineers have discovered our understanding of language may depend more heavily on vision than previously thought: under the right conditions, what you see can override what you hear.

Genetic similarities between bats and dolphins discovered Posted: 04 Sep 2013 10:25 AM PDT The evolution of similar traits in different species, a process known as convergent evolution, is widespread not only at the physical level, but also at the genetic level, according to new research.

Gravity variations over Earth much bigger than previously thought Posted: 04 Sep 2013 07:53 AM PDT Scientists have created the highest-resolution maps of Earth's gravity field to date -- showing gravitational variations up to 40 percent larger than previously assumed. New gravity maps revealed the variations of free-fall gravity over Earth were much bigger than previously thought.

The African fish that lives fast and dies young Posted: 04 Sep 2013 06:38 AM PDT African annual fish take the adage 'live fast, die young' to a whole new level with the discovery that their short lifespan is accompanied by the most rapid sexual maturation of any vertebrate species. Extreme environments can give rise to extreme adaptations. The tiny annual fish of Africa live in temporary puddles created by seasonal rainfall, and so must grow and reproduce quickly in order to lay their hardy eggs before the waters dry up. African annual fish can grow up to 23% of their body length in a day.

Unexpected magic by cosmic rays in cloud formation Posted: 04 Sep 2013 06:35 AM PDT Physicists suggested that cosmic rays, energetic particles from space, are important in the formation of clouds. Since then, experiments have demonstrated that cosmic rays actually help small clusters of molecules to form. But the cosmic-ray/cloud hypothesis seemed to run into a problem when numerical simulations of the prevailing chemical theory pointed to a failure of growth.
