Ocean-Crossing Dragonflies Discovered 95

Posted by samzenpus from the incredible-journey dept.
grrlscientist writes "While living and working as a marine biologist in Maldives, Charles Anderson noticed sudden explosions of dragonflies at certain times of year. He explains how he carefully tracked the path of a plain, little dragonfly called the Globe Skimmer, Pantala flavescens, only to discover that it had the longest migratory journey of any insect in the world."

NASA Tests Flying Airbag 118

Posted by samzenpus from the drop-the-cloud-anchor dept.
coondoggie writes "NASA is looking to reduce the deadly impact of helicopter crashes on their pilots and passengers with what the agency calls a high-tech honeycomb airbag known as a deployable energy absorber. So in order to test out its technology NASA dropped a small helicopter from a height of 35 feet to see whether its deployable energy absorber, made up of an expandable honeycomb cushion, could handle the stress. The test crash hit the ground at about 54MPH at a 33 degree angle, what NASA called a relatively severe helicopter crash."

Star Guard — an Old-School Platformer Done Right 107

Posted by Soulskill from the 39-deaths-i-am-terrible dept.
An anonymous reader writes "Rock, Paper, Shotgun points out a new game called Star Guard, a Flash-based platformer for Mac and PC that's a throwback to the early days of computer gaming, yet still entertaining. They describe it thus: 'Its greatest strength, to my mind, is throwing out the old-school traditions of difficulty. It does certainly get tricky, requiring the platformer standbys of carefully timed jumps and learning enemy patterns — there's something of a Metroid vibe to it. But you don't get punished for failing to meet one of its challenges — you're just plunged a few feet back to most recent checkpoint, and carry on. Lives are not finite, but the small mound of green pixels that mark your corpses are a maudlin testament to your ineptitude. However, death is useful — I ritually found myself sending in a suicide spaceman, taking out an enemy or a mine so that the path was clear for my next go. ... However, it doesn't leave people who pride themselves on their gaming skill, and demand their games to be hard, out in the cold. At the end of each level, your score alters dramatically depending on how many times you died.'"
