IBM researchers used a new nanopatterning technique to create the "world' smallest" 3D map of the Earth. Approximately 1000 of them would fit on a single grain of salt. Separately, they also carved out a 25-nanometer tall model of the Matterhorn. A nanometer, of course, is one-billionth of a meter, so that's a 1:5 billion scale nano-mountain.
From IBM Research:
The core component of the new technique, which was developed by a team of IBM scientists, is a tiny, very sharp silicon tip measuring 500 nanometers in length and only a few nanometers at its apex...
The tip, similar to the kind used in atomic force microscopes, is attached to a bendable cantilever that controllably scans the surface of the substrate material with the accuracy of one nanometer–a millionth of a millimeter. By applying heat and force, the nano-sized tip can remove substrate material based on predefined patterns, thus operating like a "nanomilling" machine with ultra-high precision.
The sale of Time Warner Cable to Charter Communications is completed today, and former TWC customers (including me) can probably look forward to a whole new era of crappy service, Netflix throttling, and horrible customer service experiences under our new broadband overlords.
Streaming video service Netflix today launched Fast.com, which shows you your internet connections in megabits per second. You can use it on your mobile or over your home broadband connection, and it doesn’t require a Netflix account.
Carnegie Mellon University researchers developed a system that turns your arm into a trackpad. Video demo above. From their scientific paper: It consists of a ring, which emits a continuous high frequency AC signal, and a sensing wristband with multiple electrodes. Due to the phase delay inherent in a high-frequency AC signal propagating through the […]
