...aken in the 1980s with those taken in the 1990s to determine how levels were changing over time. They found that areas where farmland has been abandoned during the last century have early generations of trees that produce higher levels of VOCs than older growth forests.

...Rohwer said he hopes to conduct further surveys to determine the strength of that desire. "There's a huge cost to finding out because there's all this mistrust that comes in," he said. "It has the potential to break up families and may not be in the male's best interest." ...UCSF scientist Joe Derisi named MaCarthur Fellow

He also is hoping to begin using the tool with neurologist Stephen Hauser, MD, to examine multiple sclerosis, which is believed to have a viral component in some cases. ...A test case for DNA barcodes to identify species

... the spread of leukemia, the researchers wanted to determine the gene's normal function. This was accomplished by deleting the c-myb gene in a mouse model. New technology allowed the scientists to delete c-myb from one specific type of tissue in the model rather than from the entire organism. "We removed the ...Atacama rover helps NASA learn to search for life on Mars
... Scientists conducted experiments with Hyperion to determine the optimum design, software and instrumentation for a robot for extensive investigations during 2004-05 of desert life. Zoe and its instrument payload are the result of the first year's research. "The project is going a step further by tryin...Hidden diversity: DNA 'barcoding' reveals a common butterfly is actually 10 different species
...Guelph in Canada, the Barcode of Life Database can determine patterns of COI gene variation within a given group of specimens. If the specimens in question differ by more than a few percent in their base pairs of DNA in this gene, it is likely that they have come from different populations.

... "The basic idea that drove this research was to determine where the newly introduced populations in Florida and elsewhere came from," said Kolbe. "We discovered that once an introduced species gets established in an area it can become a source for introductions elsewhere. And we also found that genetic va...Fortifying food with folic acid benefits babies
