A team of scientists, led by Alfred S. McEwan of the Lunar and Planetary Laboratory, University of Arizona, Tucson, may have identified the tell-tale signs of “seasonal flows” (small channels attributable to downhill water movements) on certain Martian slopes. The potentially game-changing discovery, which was enabled by an analysis performed by an undergraduate student, has got the astronomy, planetary and astrobiology science communities rather excited.
“Spirit bears” (aka Kermode bears) are a very unique subspecies of North American black bears. About 1/10th of the Kermode bear subspecies are born white (hence the name), due to some sort of genetic variation scientists are yet to pinpoint. The most common belief is that bears are born with white hair for the same
