Ancient DNA provides clues to the evolution of social behavior

...What we're trying to do is basically make a moving picture of their history instead of just a snapshot.'' Adopting a colonial lifestyle may have been the key to the rodent's survival, Hadly asserts, and could provide insight into the evolution of social behavior in other animals, including ants and humans. ...

Waking a sleeping virus

Diverse tropical forests defy metabolic ecology models

...ptured or even decently approximated by any single picture or formula." Tropical forests give modelers a run for their money. Trees range from spindly understory shrubs to enormous buttress-rooted rainforest giants festooned with vines and peppered with orchids, ferns and bromeliads. Tropical trees depend ...

New DNA 'fingerprinting' technique separates hemp from marijuana

...pattern of fragment lengths adds up to a composite picture of each cultivar. "With this technique, we find hundreds of markers scattered across the genome," said Weiblen. "The larger number of markers, compared to other techniques, gives us the power to separate the cultivars." The Cannabis plant has been ...

U of MN researchers identify ataxia gene

...e of ataxia provides patients with a more accurate picture of what the future holds. Ranum added: "Finding the SCA5 mutation in Lincoln's family makes it possible to test Lincoln's DNA ?if it becomes available ?to unequivocally determine if he carried the mutation and had or would have developed the disease...

MIT: Oceans are a major gene swap-meet for plankton

...lt of the new findings, "we are beginning to get a picture of gene diversity and gene flow in the most abundant photosynthetic cell on the planet, the Prochlorococcus group of planktonic microbes," said Chisholm, the Lee and Geraldine Martin Professor of Environmental Studies. These photosynthesizing bacte...

New RNAi tools enable systematic studies of gene function

...lies and nematodes ?it can provide a more complete picture of that process," said David Root, a senior author of the Cell paper and the director of TRC and the RNAi platform at the Broad Institute. "Thanks to this unique public-private effort, we now have new tools to enable the entire research community to ...

Scientists discover interplay between genes and viruses in tiny ocean plankton

...ld cells into new ones. "We're beginning to get a picture of gene diversity and gene flow in Prochlorococcus," Chisholm said. "These photosynthesizing bacteria form an important part of the food chain in the oceans, supply some of the oxygen we breathe, and play a role in modulating climate. It's important ...

UF scientists reveal ancient origin of vertebrate skeleton

'Banana-jawed' fossil mammal linked to rare sound-producing skill

...ists at the Duke Lemur Center have assembled a new picture of a 35-million-year-old fossil mammal -- and they even have added a hint of sound. By painstakingly measuring hundreds of specimens of a fossil mammal called Thyrohyrax, recovered from the famous fossil beds of Egypt's Fayum Province, the researche...

New technique puts brain-imaging research on its head

...uncertain because such methods don't give any true picture of what happens. Now, mechanical engineers at Washington University in St. Louis and collaborators have devised a technique on humans that for the first time shows just what the brain does when the skull accelerates.
