Submission + - Scientists Develop Solar Cell That Can Also Emit Light

Submitted by Anonymous Coward
An anonymous reader writes: Scientists at the Nanyang Technological University have developed a solar cell that not only converts sunlight into electricity but also emits light as electricity passes through it. Tuning the composition of the solar cell enables it to emit different wavelengths of light, and because it is only about 1 micrometer thick, the material is semi-translucent and therefore could potentially be used in windows. The solar cell is comprised of the semiconducting mineral perovskite, which has been studied as a replacement for silicon in solar panels since 2009. Perovskite solar cells are not yet as efficient at energy conversion as silicon solar cells, but gains in this area of development coupled with cheaper manufacturing costs (10-20 cents per watt projected as opposed to 75 cents per watt with silicon solar panels and 50 cents per watt with fossil fuels) make perovskite a popular subject matter in the solar cell industry.

Well that would present a problem! One would then wonder how those creative terrorists managed to get a jet engine to operate outside of an atmosphere. :)

But seriously, wouldn't you just compare the timing of the signals received from the jetliner of interest with the timing signals received from other, less hijacked, planes and based on their more reliable locations figure out what distance 370 must have sent from?

Not only that, but student loans are one of the few types of debt that are not normally discharged in a Chapter 7 bankruptcy filing. It's pretty much with you for life. You'd be better off putting your tuition on a credit card than taking out a student loan for it. Starting off that far in the whole with student loans is one of the worst mistakes you can make, unless you really understand what you are taking on.

Submission + - Microsoft Releases TypeScript 1.0 RC

Submitted by CMULL
CMULL writes: Microsoft unveiled TypeScript 1.0 RC in its Visual Studio 2013 Update 2 today. TypeScript is the company’s programming language that is meant for application-scale JavaScript development. Unlike Google’s programming language Dart, which is a strategy to replace JavaScript, TypeScript is a superset of JavaScript designed to strengthen the language and make up for its missing elements like larger scale application structure concepts and static typing. According to the core developer of TypeScript Anders Hejlsberg, TypeScript enables projects, multiple files and cross-platform refactoring to give the look and feel of Java or C++. TypeScript 1.0 RC is the near final version of TypeScript 1.0

Submission + - Archeological Study Contradicts The Bible (tau.ac.il)

Submitted by Anonymous Coward
An anonymous reader writes: Researchers at Tel-Aviv University in Israel used radiocarbon dating to pinpoint the date of camel domestication in the Middle East, and the results are not good for people who interpret the Bible literally. The study shows that camels were domesticated in Israel sometime around 900 B.C., not 2000 B.C. as claimed in Genesis. This shows that the text of the Bible was written long after the events described in it occurred, or that the Earth is in reality much younger than we thought.

Submission + - Will Overselling Global Warming Lead To A New Scientific Dark Age? 5

Submitted by Hugh Pickens DOT Com
Hugh Pickens DOT Com writes: Patrick Michaels writes in Forbes that atmospheric physicist Garth Paltridge has laid out several well-known uncertainties in climate forecasting including our inability to properly simulate clouds that are anything like what we see in the real world, the embarrassing lack of average surface warming now in its 17th year, and the fumbling (and contradictory) attempts to explain it away. According to Paltridge, an emeritus professor at the University of Tasmania and a fellow of the Australian Academy of Science, virtually all scientists directly involved in climate prediction are aware of the enormous uncertainties associated with their product. How then is it that those of them involved in the latest report of the Intergovernmental Panel on Climate Change (IPCC) can put their hands on their hearts and maintain there is a 95 per cent probability that human emissions of carbon dioxide have caused most of the global warming that has occurred over the last several decades? In short, there is more than enough uncertainty about the forecasting of climate to allow normal human beings to be at least reasonably hopeful that global warming might not be nearly as bad as is currently touted. Climate scientists, and indeed scientists in general, are not so lucky. They have a lot to lose if time should prove them wrong. "In the light of all this, we have at least to consider the possibility that the scientific establishment behind the global warming issue has been drawn into the trap of seriously overstating the climate problem—or, what is much the same thing, of seriously understating the uncertainties associated with the climate problem—in its effort to promote the cause," writes Paltridge. "It is a particularly nasty trap in the context of science, because it risks destroying, perhaps for centuries to come, the unique and hard-won reputation for honesty which is the basis of society’s respect for scientific endeavor."
