Fall Meeting: updated press conferences and special events
... This session will report on spacecraft Galileo's closest ever fly-by of Io, Jupiter's volcanic moon. It will focus on cooperative observations of volcanic eruptions on Io from various Galileo instruments and from Earth. (This press conference will consist of new results and will not duplicate the Novembe...Evidence of bacterial life found in deepest-yet Antarctic ice-core
...ial lakean extreme environment that may be Earth's closest analog to a frozen moon of Jupiter. Evidence for the microbial life thousands of meters below the ice sheet is presented in a paper by a team headed by University of Hawai'i Oceanographer David Karl. The paper is one of two on the subject appearing i...Last unidentified sport fish in North America gets a scientific name
...no one was certain the fish was different from its closest relative, the spotted bass until Williams and Burgess noted key differences including coloration, absence of teeth on the tongue and number of rows of scales.

Their closest relatives are a group called Deinococcus, which are known for their extremely efficient DNA repair mechanisms.

"It is the closest activity to a challenging card sorting task that also contains multiple factors that should stimulate the dorsolateral cortex.

...c analysis was designed to find the first flower's closest living next of kin among 150 species whose genetic origins are thought to be the most ancient. The analysis revealed that the title of "oldest living flower" is shared by two very different-looking plants--water lilies and a rare woody shrub named A......avian tree since the discovery of specimens of the closest relative to living birds, Ichthyornis, first discovered more than 100 years ago in Kansas. These specimens of Ichthyornis are part of the permanent collection at Yales Peabody Museum of Natural History. Clarke said the fossil dispels the notion that ...Scientists shake up "family tree" of green plants
.... In fact, ferns and horsetails, together, are the closest living relatives to seed plants. "Today's systematists are using genomic tools to re-write the textbooks on animal and plant evolution," says James Rodman, program director in NSF's division of environmental biology, which funded the research. "......idence that ferns and horsetails are one another's closest relatives and the group most closely related to the seed plants. "It clarifies one big chunk of the tree," Mishler said. "We haven't completed the whole tree, but these papers one at a time have dealt with all aspects of the green part of the tree of......, they found in C. elegans, ins-1 proved to be the closest relative of human insulin, as determined by sequence and protein structure similarity. Furthermore, Dr. Ruvkun and colleagues found that ins-1 and human insulin both function in the DAF-2 pathway in worms, and generate identical physiological effect...New technology expands 'molecular photography' options
..., cataloging all of the proteins it finds. "You're closest to finding out what's going on in vivo if you don't have to manipulate the tissue a great deal," Caprioli said. "With Imaging Mass Spectrometry, there's really minimal preparation of the tissue. It's an important tool in the discovery process when ...Fly on a treadmill demonstrates super directional hearing

Then the fly's nervous system (its fused neural ganglia and a tiny brain) instantaneously calculates the difference in pressure between the two ears and signals ...For whales and seals the ocean is not blue
...errestrial artiodactyls (even-toed ungulates), the closest terrestrial relative of the whales is the hippopotamus. Seals have evolved from terrestrial carnivores, among their close relatives are the wolf, ferret and river otter. In all of these terrestrial relatives, the researchers found blue cones. The los...Indian caste groups have differing genetic relationships to Europeans and Asians
...Thus, it is an obvious question to ask who are the closest relatives of Indians and are the different castes more or less similar to the same relatives," says lead study author Michael Bamshad, M.D., a geneticist at the University of Utah.
