Researchers have proposed a new system of DNA analysis that would allow field biologists to quickly scan a specimen and compare it against a global database of identified species. The system of DNA 'bar codes' could assist in the urgent task of cataloging unknown species before their ranks are decimated by extinction.
A hugely ambitious project to find and name every species on Earth within the next 25 years has been launched by scientists. The internet and the development of DNA sequencing technology make the goal achievable, they say.
Iowa State University researchers have reported that they found more evidence that pollen from bioengineered corn could be deadly for Monarch butterflies, prompting environmentalists to renew demands for tighter restrictions on the crop.
A sign by the small enclosure near the Bonorong Park Wildlife Center entrance says ''Tasmanian tiger'' but the fabled carnivore is nowhere to be seen. The last known Tasmanian tiger, or thylacine, died in captivity in 1936, but a team of Australian biologists believes the animal's extinction may simply be a 70-year hiccup. DNA from a Tasmanian tiger has been found and cloning is underway.
A researcher who sees cloning as one tool to be used in saving endangered species said scientists should keep open minds.
Scientists are discovering techniques to clone species at the same time that other scientists are warnign about an extinction crisis. The 21st century may see both mass extinctions and astonishing revivals as the result of genetic engineering technology.
