Research into goshawk flight could inform the design of next generation UAVS. Where prior research into bird flight has focused on steady flight, new research from MIT examines the patterns of birds adept at flying in "cluttered environments" to find principles applicable to robot motion planning. It's research that might one day find practical applications in engineering, including fast, agile UAVs.  Read More

Web-slinging arachnids already have researchers toiling away looking to replicate the remarkable properties of spider silk. Now spiders, along with their insect and crustacean arthropod cousins, have provided inspiration for a new material that is cheap to produce, biodegradable, and biocompatible. Its creators say the material, dubbed "Shrilk," has the potential to replace plastics in consumer products and could also be used safely in a variety of medical applications, such as suturing wounds or serving as scaffolding for tissue regeneration.  Read More

Starting next year, computers will be available with three-dimensional transistors – these will incorporate vertical components, unlike the flat chips that we’re used to seeing. This structure will allow them to have shorter gates, which are the components that allow the transistors to switch the electrical current on and off, and to direct its flow. The shorter the gate, the faster the computer can operate. While the new 3D transistors will have a gate length of 22 nanometers, as opposed to the present length of about 45, the use of silicon as a construction material limits how much shorter they could ultimately get. That’s why scientists from Purdue and Harvard universities have created prototype 3D transistors made out of indium-gallium-arsenide – the same compound recently used in a record-breaking solar cell.  Read More

If you've seen the film The Social Network, then you might have wondered about the identical Winklevoss twins - were a real-life pair of twins cast for the roles, or was it a bit of Hollywood magic? Well, it was magic. Although two different actors' bodies were used, their faces both belonged to actor Armie Hammer. After the movie was shot, the body double's face was digitally replaced with Armie's. While such computer-enabled face-swapping trickery has so far been available only to feature film-makers with deep pockets, that could be about to change, thanks to research being conducted at Harvard University.  Read More

More and more, it’s looking like many of the robots in the not-too-distant future won’t be hard, humanoid C-3PO-like affairs, but will instead be squishy, soft-bodied devices. Not only would such robots be better able to withstand mechanical shock, vibration and compression, but they would also be able to do things like squeezing through small spaces – an ability which come in very handy in settings like disaster sites or battlefields. Previous experiments with soft-bodied robots have included Tufts University’s GoQBot, which was clearly inspired by caterpillars. More recently, scientists from Harvard University demonstrated a squishy creation of their own, which could probably best be likened to a robotic starfish ... although it was apparently also inspired by squids.  Read More

Do you think that you’ll never be able to afford a robot of your own that isn’t a toy? Well, if you can get Swiss robot-maker K-Team Corporation to sell you one, chances are you can easily afford a Kilobot – perhaps even a whole bunch of them. Designed and first built by Harvard University’s Self-Organizing Systems Research Group, the three-legged robots aren’t much larger than the 3.4-volt button cell batteries that power them, and move by vibrating across smooth, flat surfaces. They were created to study robotic swarming behavior, with the intention that tens, hundreds or even thousands of them could be used simultaneously in one experiment. Harvard has just announced that it has licensed the Kilobot technology to K-Team, which will commercially manufacture the robots so that other groups and institutions can purchase them for their own research.  Read More

It's difficult to look at the night sky and not wonder whether intelligent life exists out there. Indeed, the odds are very much in favor of there being countless civilizations scattered throughout the heavens, but the challenge remains in proving it. Recently, two scientists hit upon the novel but common-sense idea of searching for city lights on the dark side of distant worlds- a task advanced next-gen earth and space-based telescopes will likely be able to tackle in the not-too-distant future.  Read More

While there are a great many people who want to lose weight by dieting, there aren't too many who can afford to have a nutritionist assess the caloric value of all their food choices. Using the PlateMate system, however, members can get an online community of laypeople to do exactly that - and for considerably less money. Although taking such an approach to nutrition might sound kind of iffy, calorie estimates generated by the crowd-sourced system are apparently just as accurate as those provided by trained nutritionists, and more accurate than self-kept logs.  Read More

Who doesn't like carnivorous plants? They eat pesky bugs, they look like something out of Flash Gordon, and now it turns out that one of them has inspired a new type of liquid-repellent surface. The inspirational flora is the pitcher plant, which is shaped like - well, like a water pitcher, or perhaps a wide-end-up trumpet. When insects step onto its slippery inner surface, they lose their footing and fall down into a pool of collected rainwater in its base, where they are digested. Scientists from Harvard University's School of Engineering and Applied Sciences (SEAS) have copied the structure of that inner surface and come up with a material that resists not only most liquids, but also ice and bacteria, and it does so under a wide range of conditions.  Read More
