Arachnoscelis arachnoids, a rare species of katydid from Central Northeast of Colombia, uses elastic energy and wing movement to reach volumes greater than 110 decibels, which is louder than a diesel truck or a subway train. Female Arachnoscelis arachnoids (Benedict Chivers et al) Benedict Chivers from the University of Lincoln, UK, with colleagues found a region in Colombia where Arachnoscelis arachnoids (previously known from only one specimen)...

Water-carved valley on Mars. The researchers have found that some of these valleys appear to have been formed by orographic precipitation - rain or snow that falls when moist air is pushed upward by mountain ridges or raised crater rims. The findings suggest that at least some of the water on ancient Mars fell from the atmosphere, rather than bubbling up from the subsurface (NASA)
