Professor analyzes nuclear receptors in bee genome
10-25-2006 · EurekAlert!
Susan Fahrbach, a Wake Forest University biologist, is among the more than 170 researchers who helped decode the honey bee genome. She contributed to the article on the bee genome sequence that appears in the October 26 issue of Nature. Her piece of the puzzle -- analyzing the nuclear hormone receptors found in the bee genome -- also appears in the current issue of Insect Molecular Biology.

Researchers find best way to detect airborne pathogens
03-21-2007 · EurekAlert!
Current methods used to sniff out dangerous airborne pathogens may wrongly suggest that there is no threat to health when, in reality, there may be. But researchers have found a better method for collecting and analyzing these germs that could give a more accurate assessment of their actual threat. For example, the findings may make it easier to detect airborne pathogens in low concentrations.

Condition of bluefin tuna in gulf of maine is declining
08-23-2007 · EurekAlert!
The quality of giant bluefin tuna caught in the Gulf of Maine has declined significantly since the early 1990s, researchers at the University of New Hampshire have found by analyzing detailed logbooks from a commercial tuna grader at the Yankee Fisherman's Co-op. The findings, published this week in Fishery Bulletin, indicate potential changes in food sources, shifts in reproductive or migratory patterns, or the impact of fishing may be the cause of this decline.

'Mismatched' prostate cancer treatment more common than expected
11-26-2007 · EurekAlert!
More than a third of men with early prostate cancer who participated in a study analyzing treatment choice received therapies that might not be appropriate, based on pre-existing problems with urinary, bowel or sexual function. The prevalence of these treatment "mismatches" could reflect patient unwillingness to discuss such problems with their physicians.

Lost forest yields several new species
08-07-2007 · EurekAlert!
An expedition led by the Wildlife Conservation Society to a remote corner of the eastern Democratic Republic of Congo has uncovered unique forests which, so far, have been found to contain six animal species new to science: a bat, a rodent, two shrews and two frogs.

Invisible for electrons
03-06-2007 · EurekAlert!
As thin as it gets: the carbon membranes recently created by Max Planck scientists are only one atom thick. For electrons, such membranes are almost completely transparent -- using an electron microscope, scientists may thus be able to examine absorbed individual molecules on the membranes, and image the atomic structure of complex biological molecules. Such ultra-thin membranes may also be used to filter out gases (Nature, March 1, 2007).

In search for water on Mars, clues from Antarctica
12-09-2007 · EurekAlert!
Scientists have gathered more evidence that suggests flowing water on Mars -- by comparing images of the red planet to an otherworldly landscape on Earth. In recent years, scientists have examined images of several sites on Mars where water appears to have flowed to the surface and left behind a trail of sediment. Those sites closely resemble places where water flows today in the McMurdo Dry Valleys in Antarctica , the new study has found.
