Our understanding of the universe is expanding in all directions, expanding outwards as we see more and more of the cosmos and inwardly as we learn more about the nano world. In the nano world the tools for capturing the action shots are improving but there are still a number of destinations we are unable to explore. Organic organisms – for example, influenza virus – are too delicate for the standard tools of nano exploration :: Read the full article »»»»
Satellites envelop our world like a web, another kind of world wide web. Proving to be indispensable for communications, scientific exploration and avoiding getting lost when shopping, they have become our eyes and ears in the sky, an essential part of everyday life.
DARPA, America’s greatest research and development organizations has turned it’s attention to space junk and satellites. With such previous contributions to society such as the Internet and GPS satellites DARPA isn’t the sort of company you ignore. Sure they may have their odd flight of fancy, the flying Humvee idea turned a lot of heads, turned heads with curious looks wanting to ask flying what now? Project Phoenix aims to create a new class of satellite, the Borg Satellite.
The Borg or Tender – DARPA’s designation – space robot will be able to disassemble and maintain other satellites. Eventually DARPA hopes the Tender’s will be able build working satellites from various spare parts floating around in GEO – geostationary – orbit. Could the DARPA Borg satellites begin eating other satellites and produce kill-bots to take over the world, possibly but there are a lot of technological hurdles to overcome yet :: Read the full article »»»»
Scientists at Harvard have discovered new ways of making light dance, along the way changing the laws of reflection and refraction of light. The wonderful world of Nano particles, along with their effects on light’s behaviour were explored in order to make these discoveries. Under normal circumstances light is nice and predictable, Mr Consistent, the team from the Harvard School of Engineering and Applied Sciences – SEAS – found a loop-hole though, precise patterns of metallic nanostructures. Just as in a Carnivals Magic Mirror amusement the nanostructures were able to warp and bend light, unlike the carnival though they did not require bendy mirrors or clever lighting. Instead using Nano structures embedded in precise patterns on the surface of silicon they were able to alter lights behaviour. Their findings were published in the scientific journal Science, September 2 and have since led to the reformation of the mathematical laws of reflection and refraction, the predicted path of a ray of light bouncing of a surface or passing from medium to medium, bouncing or bending:: Read the full article »»»»
Anti-matter, the ultimate outsider in a universe of matte. Using the anti-matter hunting satellite PAMELA – Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics – scientist were able to locate a pool of anti-matter trapped within the Earth magnetic fields. Anti-matter is a mysterious type of matter, not made for this world, when it rarely does appear its only very briefly, usually leaving with a bang. While PAMELA has found a constantly replenishing source of anti-matter it’s too soon to start building the USS Enterprise just yet. The study of the fundamentals of our universe becomes a lot easier when you have actual examples to study. Read the full article »»»»
