Jybl Scientists Make Light Travel Infinitely Fast
Flowers may be silent, but scientists have just discovered that electric fields allow them to communicate with bumblebees and possibly other species, including humans. It well known that color, shape, pattern and fragrances allow flowers to
stanley website connect with pollinators, but the new study, published in the journal Science, adds electricity to this already impressive lineup. We just now have discovered that electrical potentials, an unavoidable by-product of flying in air for bumblebees and being grounded for the flower, is being exp

It another example of the beauty of evolution, added Robert, a professor in the University of Bristol School of Biological Sciences. He explained that bees have a positive electrical charge because they fly in air, which is full of all kinds of tiny particles, such as dust and charged molecules. Friction from these particles causes bees to lose electrons, leaving bumblebees positively charged. Flowers, on the other hand, are electrically connected to ground, he said. Unlike copper wire, which transfers charges very quickly, plants conduct electricity very slowly and tend to possess a negative charge. For the study, Robert and his team placed petunia flowers in an area with free-flying foraging bees. T

According to leaked documents seen by The Verge, Barnes 038; Noble is launching an 8GB version of its

From The Verge: All we know for sure is that Walmart plans to launch this new device at 12:01AM on Wednesday, February the 22nd, and deliveries of the 8GB Tablet should be arriving in stores already.
