Roland Piquepaille writes: "You all know that incandescent light bulbs are terribly inefficient, turning only 5% of the electricity it consumes into light. Fluorescent lamps are better using up to 25% of its energy as light. And solid state lighting devices lose only 50% of the energy they received. But now, researchers at Arizona State University (ASU) claim they've developed organic lighting devices which are 100% efficient. The researchers think it's possible to produce these solid-state lighting devices based on OLED technology at low cost. If this is true, this would be of major benefit to the environment by conserving energy and natural resources. Read more for additional references about these future lighting devices."

Anonymous Coward Inc. writes: "Snippet from article . "Seems like the plot of a particularly far-fetched horror film. But some scientists suggest that our love of the mobile phone could cause massive food shortages, as the world's harvests fail. They are putting forward the theory that radiation given off by mobile phones and other hi-tech gadgets is a possible answer to one of the more bizarre mysteries ever to happen in the natural world — the abrupt disappearance of the bees that pollinate crops. Late last week, some bee-keepers claimed that the phenomenon — which started in the US, then spread to continental Europe — was beginning to hit Britain as well.""

A series of quietly exhaled breaths might indicate whether or not a patient is at risk for lung cancer. Using DNA recovered from exhaled breath, researchers can examine the state of cells that line the lungs, and potentially detect cancer at an early stage, when treatment may be most successful.

Feed Smart Hydrogel Nanoparticles For Serum Cancer Biomarkers Harvesting (sciencedaily.com)

Researchers are investigating a remarkable use of nanotechnology that might change the way doctors monitor patients for cancer-indicating biomarkers. These hydrogel nanoparticles, less than one tenth the size of a red blood cell, could function like "smart" sponges, designed to soak up specific proteins in the bloodstream.

The article includes some things which are completely discredited and some things which are merely out of context. Once again, a randomly assembly of data in a popular newspaper has failed to overturn years of peer-reviewed science.
