clown tree frogs—newly discovered and already threatened?




an international team of scientists discovered two new species of clown tree frogs in the amazon region. until recently, these colorful amphibians had erroneously been considered part of another species. now, dna studies and an analysis of the calls of the examined populations revealed a much higher...



visit nasa's newly discovered planets in 'elite: dangerous'




sadly, it's unlikely that you'll ever visit the trappist-1 system's newly-discovered earth-sized planets in your lifetime... not unless someone develops near-light speed travel, anyway. however, you'll at least have the option of a virtual tour. frontier developments is promising ars technica that t...



hidden stars may make planets appear smaller




in the search for planets similar to our own, an important point of comparison is the planet's density. a low density tells scientists a planet is more likely to be gaseous like jupiter, and a high density is associated with rocky planets like earth. but a new study suggests some are less dense than...



team develops sustainable, high energy density battery

a strikingly bright pink-clawed species of pistol shrimp, discovered on the pacific coast of panama, has been given the ultimate rock and roll name in recognition of the discoverers' favourite rock band - pink floyd.



water exists as two different liquids




we normally consider liquid water as disordered with the molecules rearranging on a short time scale around some average structure. now, however, scientists at stockholm university have discovered two phases of the liquid with large differences in structure and density. the results are based on expe...
