| Dishonesty is aggressively punished in the world of paper wasps Posted: 04 Jul 2016 12:38 PM PDT Is honesty really the best policy? Isn't it more beneficial to cheat, if you can get away with it? Not if you're a paper wasp, shows new research. |
| A giant impact: Solving the mystery of how Mars' moons formed Posted: 04 Jul 2016 11:42 AM PDT Where did the two natural satellites of Mars, Phobos and Deimos, come from? For a long time, their shape suggested that they were asteroids captured by Mars. However, the shape and course of their orbits contradict this hypothesis. Two independent and complementary studies provide an answer to this question. One of these studies rules out the capture of asteroids, and shows that the only scenario compatible with the surface properties of Phobos and Deimos is that of a giant collision. In the second study, researchers used cutting-edge digital simulations to show how these satellites were able to form from the debris of a gigantic collision between Mars and a protoplanet one-third its size. |
| Teaching drones about the birds and the bees Posted: 04 Jul 2016 05:27 AM PDT Unmanned Aerial Vehicles (UAVs) of the future will be able to visually coordinate their flight and navigation just like birds and flying insects do, without needing human input, radar or even GPS satellite navigation. |
| Scamming Nemo: How cleaning fish are the 'con-men' of the coral reef Posted: 04 Jul 2016 05:26 AM PDT Cleaner wrasse perform a cleaning service for coral reef fish -- namely eating parasites off their customer's skin. However, what the females of some species actually want is to lure in clients and 'cheat' them by biting off some tasty mucus before escaping. |
