New Technology Uses Cellular Towers For Super-Accurate Weather Measurements

Iddo Genuth (903542) writes “Israeli scientists from the Tel Aviv University perfected a method for using cell phone service towers’ microwave emitters to measure rain and snow and even (for the first time ) detect fog with great accuracy over vast areas in real time. The research team members have analyzed endless amounts of raw cellular data and developed more accurate ways to measure meteorological information and added more parameters that they can now measure using their growing database. When combined with existing meteorological monitoring technologies such as radars and local ground based weather stations, the results show unprecedented level of accuracy that can give better and further weather forecast as well as special warnings about upcoming floods, fog and hail which can affect both people and crop production.” Read more of this story at Slashdot.

Sand-Based Anode Triples Lithium-Ion Battery Performance

Zothecula (1870348) writes “Conventional lithium-ion batteries rely on anodes made of graphite, but it is widely believed that the performance of this material has reached its zenith, prompting researchers to look at possible replacements. Much of the focus has been on nanoscale silicon, but it remains difficult to produce in large quantities and usually degrades quickly. Researchers at the University of California, Riverside have overcome these problems by developing a lithium-ion battery anode using sand.” Read more of this story at Slashdot.

Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment?

MojoKid (1002251) writes “Back in the day (which is a scientific measurement for anyone who used to walk to school during snowstorms, uphill, both ways), integrated audio solutions had trouble earning respect. Many enthusiasts considered a sound card an essential piece to the PC building puzzle. It’s been 25 years since the first Sound Blaster card was introduced, a pretty remarkable feat considering the diminished reliance on discrete audio in PCs, in general. These days, the Sound Blaster ZxR is Creative’s flagship audio solution for PC power users. It boasts a signal-to-noise (SNR) of 124dB that Creative claims is 89.1 times better than your motherboard’s integrated audio solution. It also features a built-in headphone amplifier, beamforming microphone, a multi-core Sound Core3D audio processor, and various proprietary audio technologies. While gaming there is no significant performance impact or benefit when going from onboard audio to the Sound Blaster ZxR. However, the Sound Blaster ZxR produced higher-quality in-game sound effects and it also produces noticeably superior audio in music and movies, provided your speakers can keep up.” Read more of this story at Slashdot.
