The modern masses can now listen to what experts say is the oldest playable recording of an American voice and the first-ever capturing of a musical performance, thanks to digital advances that allowed the sound to be transferred from flimsy tinfoil to computer. The 78-second recording was originally made on a Thomas Edison-invented phonograph, and features both music and the first recorded blooper.
Researchers at Oak Ridge National Laboratory have found that nitrogen atoms in the compound uranium nitride exhibit unexpected, distinct vibrations that form a nearly ideal realization of a physics textbook model known as the isotropic quantum harmonic oscillator.
Through a new website unveiled Wednesday, Google is opening a virtual window into the secretive data centers where an intricate maze of computers process Internet search requests, show YouTube video clips, and distribute email for millions of people. The photographic access to Google's data centers coincides with the publication of a Wired magazine article about how the company builds and operates them.
Light might one day be used to cool the materials through which it passes, instead of heating them, thanks to a breakthrough by engineers at Lehigh and Johns Hopkins Universities. The discovery could lead to smaller, lighter, and cheaper communication devices with faster switching times, increased output, and higher operating voltages.
Scientists have pieced together the sequence of events of the farthest touchdown a man-made spacecraft has ever made on an alien world. Their work in tracking the bounces, wobbles, and skids the probe made before coming to rest on Titan reveals new clues about the Saturn moon’s surface and helps plan future missions to moons and planets.
After leading mass spectrometer manufacturers agreed to license technology that has enabled researchers to develop software allows scientists to easily use and share research data collected across proprietary instrument platforms. Called the ProteoWizard Toolkit, this cross-platform set of libraries and applications is expected to bolster large-scale biological research and help improve the understanding of complex diseases like cancer.
Silicon is used in components, e.g. filters or deflectors, for telecommunications. So far, however, all these components have been flat, or 2D. Researchers have developed a new etching method for these structures that results 3D microstructures in silicon. Suitable for fiber optic communications, their optical properties are adjustable at the micrometer scale.
Design for remotely monitoring large infrastructures, the longest fiber-optic sensor network yet designed would measure 250 km in length and be equipped with multiplexing technology to allow multiple information channels to be carried. Theorized by a researcher in Spain, the network would allow long-distance analysis with requiring a power source for the sensors.
Digital cameras and camcorders deliver high resolution film sequences that are several gigabytes in size. These can take several minutes to transfer wirelessly to your home computer via Bluetooth.
