Many of life's building blocks, such as amino acids, sugars and other molecules, are chiral -- meaning they come in two identical forms, mirror images of each other. Most life on Earth tends to prefer one side over the other, such as right-handed glucose molecules. But some forms of bacteria are less choosy.
Most life is left-handed, but its lower forms are ambidextrous, according to a new study reported in New Scientist. This might complicate the search for life on other planets, but it could also explain the Viking Mars landers' odd findings four decades ago.
Tossing a Rubik's Cube into an aquarium yields interesting results

There are plenty of times when a third hand would be helpful, but solving a Rubik's Cube isn't really one of them. Despite that, a study in England has been giving 25 octopuses a chance to use all eight of their arms to fail miserably like the rest of us. The research isn’t actually focused on some savant octopus solving the game but rather with which arm they choose to fail.
