Stray labrador rescues blind pooch by becoming first canine-to-canine guide dog

Two-year-old Tanner was born blind and has a seizure disorder. He was sent to Sooner Golden Retriever Rescue organization, Oklahoma City, after his owner died. Scroll down for video Guide dog: Tanner, a blind two-year-old golden retriever who was nearly put down because of his fits, has been given a new lease of life by a one-year-old black labrador called Blair Due to the stress of his loss, his seizures became worse, making him hard to look after as he would defecate and urinate when fitting.

Local vet, Mike Jones of Woodland West Animal Hospital, Tulsa, told ABC News he even recommended putting the dog down, to relieve Tanner of his - and his caretakers' - misery. BBC Nature - Plant evolved a bat beckoning beacon. 29 July 2011Last updated at 02:29 By Victoria Gill Science reporter, BBC Nature The dish-shaped leaves emit a powerful echo that helps the bat locate the plant A rainforest vine has evolved dish-shaped leaves to attract the bats that pollinate it, scientists have found.

Tests revealed that the leaves were supremely efficient at bouncing back the sound pulses the flying mammals used to navigate. When the leaves were present the bats located the plant twice as quickly as when these echoing leaves were removed. A team of scientists in the UK and Germany reported its findings in the journal Science. The study is the first to find a plant with "specialised acoustic features" to help bat pollinators find them using sound. Most bats send out pulses of sound to find their way around; the way they sense objects in their environment by sensing how these pulses bounce off them is known as echolocation. "What we've found is the echolocating equivalent to colourful flowers. Wik-Bee Leaks: EPA Document Shows It Knowingly Allowed Pesticide That Kills Honey Bees.

The world honey bee population has plunged in recent years, worrying beekeepers and farmers who know how critical bee pollination is for many crops. A number of theories have popped up as to why the North American honey bee population has declined--electromagnetic radiation, malnutrition, and climate change have all been pinpointed. Now a leaked EPA document reveals that the agency allowed the widespread use of a bee-toxic pesticide, despite warnings from EPA scientists. The document, which was leaked to a Colorado beekeeper, shows that the EPA has ignored warnings about the use of clothianidin, a pesticide produced by Bayer that mainly is used to pre-treat corn seeds.

The pesticide scooped up $262 million in sales in 2009 by farmers, who also use the substance on canola, soy, sugar beets, sunflowers, and wheat, according to Grist. The leaked document (PDF) was put out in response to Bayer's request to approve use of the pesticide on cotton and mustard.

The fossil, found in China, is a very complete 30cm (12in) lizard with more than a dozen embryos in its body. Researchers from University College London, who studied the fossil, say it was just days from giving birth when it died and was buried during the Cretaceous period. The team reports the findings in the journal Naturwissenschaften. The fossil is especially interesting to scientists because it is a reptile that produced live young rather than laying eggs. Only 20% of living lizards and snakes produce live young, and this shows it is an ancient, if unusual, trait. "I didn't think much of the fossil when I first saw it," said Prof Susan Evans, joint lead author of the paper, from University College London. BBC Nature - Sepia cuttlefish videos, news and facts.
