A British lab provided initial independent confirmation that the United States has its first case of mad cow disease, U.S. agriculture officials said. Federal investigators labored to trace the path the infected animal took from birth to slaughter.Scientists at the Veterinary Laboratories Agency in Weybridge, England, told the U.S. Agriculture Department Thursday that they concur with the reading of tests on the stricken Holstein cow that led U.S. officials to conclude the animal had the brain-wasting disease, U.S. officials said. We are considering this confirmation, said USDA spokeswoman Alisa Harrison, adding that the English la stanley cup b still will conduct its own test using another sample from the cow s brain. Final test results on the cow from Washington state were expected by the end of the week, she said.Professor Steven Edwards, chief of the British lab, said those results already have been given to USDA. But Edwards refused to disclose whether the tests show that the animal had mad cow disease, or bovine spongiform encephalopathy.The 4,000-head Washington state dairy herd t stanley uk he lone infected cow was part of remains under quarantine.

When it comes to camouflage, we lowly humans are far behind the cephalop stanley cup od. Octopus, squid, and cuttlefish have the amazing ability to change color or texture鈥攇oing from scarlet red to bone white, bumpy to smooth in just seconds. But we ;re making progress. Scientists at MIT and Duke have created a new stretchy camouflage skin inspired by these creatures. Octopus and other cephalopods hide their colors inside tiny pigment sacs in their skin. As they expand or contract their muscles, different amounts of light bounce off the pigment, creating a rainbow of possible hues. The synthetic skin, made of stretchy polymer, works in roughly the same way. Dyes are embedded in the polymer, and when a voltage is applied, the polymer creases up. It can immediately become fluorescent red, for example, or become covered in bumps. This very basic research could eventually have obvious applications for camouflage. Another group of researchers have cr stanley mugs eated a different octopus-inspired camouflage skin that dynamically responds to light. Their skin is made out of different materials, and its overall look is more pixelated. If we could someday combine the two鈥攕eamless-looking skin and automatically res stanley trinkflaschen ponse to light鈥攚e might have a shot going of toe-to-tentacle with cephalopods.
