Surprising new species of light-harvesting bacterium discovered in Yellowstone
...as a tourists' wonderland that is full of animals, strange rock formations, geysers, and colorful hot springs, but it is also a scientific reservoir housing what may be the world's largest diversity of thermophilic (heat-loving) bacteria. Yellowstone habitats have been explored since the 1960s for new orga...Sea anemone genome provides new view of our multi-celled ancestors
...ientists usually distinguish between the sponges - strange animals unlike any other - and all the rest, which are dubbed eumetazoans (literally "true animals") and are characterized by defined tissues and distinct embryonic layers. "Anything the sea anemone has that also is found in humans, flies, snails o...Some forest birds can survive in agricultural countryside with limited habitat conservation
... a slow-moving radio signal to the forest floor, a strange occurrence since most of the bird species prefer tree branches. As the signal became louder, the researcher suddenly realized it was coming from a bushmaster, the deadliest snake in Latin America. The 15-foot snake had eaten both the bird and its rad...From ink to optics, study of particle mixtures yields fundamental insights

This strange behavior results from the previously observed fact that like-charged particles attract one another at close distances instead of the usual repulsion. At a certain intermediate distance, similarly charged particles switch from being strongly repulsed...Press conferences at the year's largest physics meeting

Consequentially, Schwartz argues that molecular change is brought about only by significant environmental stressors, such as rapid temperature change, severe dietary change, or even physical crowd...Scientists discover new species of distinctive cloud-forest rodent
.... The nocturnal, climbing rodent is beautiful yet strange looking, with long dense fur, a broad blocky head, and thickly furred tail. A blackish crest of fur on the crown, nape and shoulders add to its distinctive appearance.

... similar to humans. "Metabolic disease isn't some strange thing having just to do with humans," said Marden. "Animals in general suffer from these symptoms." The work is also novel because it links metabolic disease to a supposedly harmless parasite living in the dragonfly's gut. The parasites, known as...ACS News Service Weekly PressPac -- Nov. 8, 2006

Inherently fluorescent, expanded DNA glows in ways that may make xDNA useful as a medical and scientific probe. Eric T.
