spopepro writes "While un-captioned cats might be of limited interest to the /. community, I found this column on how a fabricated statistic takes on a life of its own interesting. Starting with the Humane Society of the United States' (HSUS) claim that the unsterilized offspring of a cat will '...result in 420,000 cats in 5 years,' the author looks at other erroneous numbers, where they came from and why they won't go away."

They typically include trigonometric functions, logarithms, factorials, parentheses and a memory function. However, the calculators featured in this article are significantly more sophisticated with the ability to process difficult mathematical functions, to plot graphs in 2D and 3D, and much more. Occasionally, the calculator tool provided with an operating system did not engender any confidence.

Altered Organism Triples Solar Cell Efficiency 158

Posted by ScuttleMonkey on Friday April 10, 2009 @04:12PM from the shiny-happy-algae dept.

An anonymous reader writes "By harnessing the shells of living organisms in the sea, microscopic algae called diatoms, engineers have tripled the efficiency of experimental dye-sensitized solar cells. The diatoms were fed a diet of titanium dioxide, the main ingredient for thin film solar cells, instead of their usual meal which is silica (silicon dioxide). As a result, their shells became photovoltaic when coated with dyes. The result is a thin-film dye-sensitized solar cell that is three times more efficient than those without the diatoms."
