If you've ever watched an octopus, you may have noticed how they can deliver powerful grasping force when necessary, yet can also squeeze through tiny openings by essentially making themselves "liquid." Now imagine if there were robots that could do the same thing. They could conceivably squirm through debris to reach buried survivors at disaster sites, or even travel through patients' bodies to perform medical procedures. An international team of scientists is working on making such technology a reality, using a combination of polyurethane foam and wax.
In the field of exotic new materials, we've examined one of the strongest ones
declared to be impossible; scientists now report creating "forbidden" materials, out of ordinary table salt, that violate classical rules of chemistry. Not only does the development challenge the theoretical foundation of known chemistry, but it is also expected to lead to the discovery of new exotic chemical compounds with practical uses and shed light on the composition of early planetary cores.
Much of the abundant mechanical energy around us is irregular and oscillatory and can be somewhat difficult to efficiently tap into. Typical energy harvesting systems tend to be built for low power applications in the milliwatts range but researchers from New York's Stony Brook University have developed a new patent-pending electromagnetic energy harvester capable of harnessing the vibrations of a locomotive thundering down a stretch of track to power signal lights, structural monitoring systems or even track switches.
If you’re impressed by the 4K
TVs set to hit the market from the likes of Sony
, then get an eyeful of the new Reality Deck officially opened at New York’s Stony Brook University (SBU) last week. Described by its creator as the closest thing in the world to Star Trek’s holodeck, the four walls of the Reality Deck are covered in a total of 416 high resolution screens that provide a total resolution of 1.5 billion pixels. SBU says this makes it the largest resolution immersive display ever built driven by a graphic supercomputer.
There's no denying that pacemakers are life-saving devices, but they do have their limitations. These include the facts that their metal leads can break, they need to be surgically accessed if their batteries run out, and they can be disrupted by strong magnetic fields. Some or all of these problems may one day become things of the past, however, due to research currently being conducted at New York's Stony Brook University - scientists there are working towards the development of pacemakers that control the heart through pulses of light.
