By MacGregor Campbell Video can capture science in action like nothing else – and New Scientist has scoured the web to bring you the 10 best clips posted this month. At a recent conference in Anchorage, Alaska, the US National Institute of Standards and Technology put tiny robots to the test. With a microchip as their playing field, they battled it out in a number of events. Watch: original video                 Most robots have rigid bodies, but these supple robotic caterpillars are an exception. Barry Trimmer and his team at Tufts University in Medford, Massachusetts, took inspiration from giant green caterpillars for their design. Watch: original video                 It seems like the punishment for a drunken night out isn’t uniquely human. A team lead by Lindy Holden-Dye at the University of Southampton, UK, studied boozed-up roundworms and found that they suffer writhe-inducing hangovers. Watch: original video                 The Deepwater Horizon oil spill continues to ravage the Gulf of Mexico. Some have suggested extreme measures to stop the flow. A vintage propaganda film shows the nuclear option – literally: Soviet engineers nuking a blown-out natural gas well. Watch: original video                 It’s not a magic trick: it is possible to instantly freeze a bottle of water by giving it a whack. The water will first have to be supercooled though, as demonstrated in a video by a team from the French Commission for Atomic Energy and Alternative Energies (CEA) and National Centre for Scientific Research (CNRS) and the European Synchrotron Radiation Facility (ESRF). Watch: original video                 Now we don’t have to imagine the view from Mars orbit. A time-lapse video from the European Space Agency’s Mars Express spacecraft takes us on a spin around the planet. Watch: original video                 How does HIV spread from an infected cell to a healthy one? A team from the University of California, Davis, and Mount Sinai School of Medicine in New York captured the process on video for the first time. By dying viral particles with a fluorescent green dye, they were able to see the infection in action. Watch: original video                 You’ve probably never watched an active lava pond on a volcano up close. See what you’re missing in new thermal video footage captured by a team from the US Geological Survey. Watch: original video                 The starry southern hemisphere above the Cotopaxi volcano is a sight to behold. Some new video footage shot by Stéphane Guisard shows shooting stars, the Coalsack nebula, the Southern Cross and the Milky Way. He even captured the flashlights from a group of climbers near the end of the video. Watch: original video                 These miniature robot helicopters can perform some mean stunts. A model developed at the General Robotics, Automation, Sensing and Perception (GRASP) Laboratory at the University of Pennsylvania in Philadelphia can flip, swarm, perch, and fly through windows.
