Nanorobot fabrication makes ultrasmall sensors possible
How do you build an infrared (IR) camera that is small enough to fit on a mini-unmanned aerial vehicle (UAV) without cryogenic cooling? Call in the nanobots.
Researchers working with the Office of Naval Research (ONR) have developed a way to build extremely small sensors using nanorobot fabrication. This new process, created by Harold Szu and James Buss of ONR and implemented by Xi Ning of Michigan State University, allows a human operator using a powerful microscope and hand-held controller to manipulate nano-sized contact points remotely--like using extremely small hands--to construct the pixel elements that will form the heart of the sensor. Each pixel will be composed of carbon nanotubes, which have nanoscale diameters and submicron lengths. Because of the one-dimensional nature of carbon nanotubes, they have significantly lower thermal noise than traditional semi-conductors. A full-sized camera incorporating this technology would be inexpensive and lightweight--about one tenth the cost, weight, and size of a conventional digital camera.

NASA keeps watch over space explosions

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
