Healthcare for the US Navy's animal warriors could help people stay healthierMay 10, 2012Military patrol dogs with your keen sense of smell, step aside. The U.S. Navy has enlisted the biological sonar and other abilities of bottlenose dolphins and California sea lions to protect harbors from enemy swimmers, detect explosives on the seafloor and perform other tasks. An article in the current edition of Chemical & Engineering News (C&EN) focuses on the Navy's health program for marine mammals and how it may also help keep people healthy. C&EN Associate Editor Lauren K. Wolf explains that the Navy invests a lot of time and money in training these animals and, naturally, wants to keep them in tip-top shape when they deploy to places like Iraq or Korea. Their missions can involve guiding sailors through mine-laden waters or attaching recovery lines to lost equipment on the seafloor. When one of the roughly 120 animals gets sick, a team of veterinarians carefully evaluates and treats its illness. Because of the Navy's medical care, the animals are living two and three times longer than is common in the wild, leading to illnesses also seen in older humans, like high cholesterol and chronic inflammation. Wolf reports that the Navy is looking to apply its growing understanding of ailments in marine mammals to develop advances in human medical care. For instance, vets have noticed that dolphins show symptoms similar to diabetes, with spiking blood sugar after meals, but they are able to live with the condition. Wolf says the researchers are looking for a genetic "switch" the dolphins might use to control their diabetes that could lead to treatments for humans living with the disease. Similarly, dolphins show extraordinary healing abilities that Navy researchers think may be linked to the animals' stem cells. The scientists are extracting stem cells from dolphins and testing to see whether their application can speed up wound healing and reduce scarring. If successful, the technique may one day be useful for humans, too. ### The American Chemical Society is a nonprofit organization chartered by the U.S. Congress. With more than 164,000 members, ACS is the world's largest scientific society and a global leader in providing access to chemistry-related research through its multiple databases, peer-reviewed journals and scientific conferences. Its main offices are in Washington, D.C., and Columbus, Ohio.

New study finds blind people have the potential to use their 'inner bat' to locate objects New research from the University of Southampton has shown that blind and visually impaired people have the potential to use echolocation, similar to that used by bats and dolphins, to determine the location of an object. Researchers discover world's most extreme hearing animal Researchers at the University of Strathclyde have discovered that the greater wax moth is capable of sensing sound frequencies of up to 300kHz - the highest recorded frequency sensitivity of any animal in the natural world. An Ancient Biosonar Sheds New Light on the Evolution of Echolocation in Toothed Whales Some thirty million years ago, Ganges river dolphins diverged from other toothed whales, making them one of the oldest species of aquatic mammals that use echolocation, or biosonar, to navigate and find food. Vortex loops could untie knotty physics problems University of Chicago physicists have succeeding in creating a vortex knot-a feat akin to tying a smoke ring into a knot. Linked and knotted vortex loops have existed in theory for more than a century, but creating them in the laboratory had previously eluded scientists. Can plants be altruistic? You bet, says new CU-Boulder-led study We've all heard examples of animal altruism: Dogs caring for orphaned kittens, chimps sharing food or dolphins nudging injured mates to the surface. Now, a study led by the University of Colorado Boulder suggests some plants are altruistic too. Big brains are pricey, guppy study shows Bigger brains can make animals, well, brainier, but that boost in brain size and ability comes at a price. Dolphin hearing system component found in insects A hearing system component thought to be unique in toothed whales like dolphins has been discovered in insects, following research involving the University of Strathclyde. Recent studies bring fossils and genes together to piece together evolutionary history Paleontology, with its rocks and fossils, seems far removed from the world of developmental genetics, with its petri dishes and embryos. Manatees Reflect Quality of Health in Marine Ecosystems, Longterm Study Finds A longterm study conducted by researchers at George Mason University may be a benchmark in determining health threats to marine mammals.
