Hydrogen and methane provide raw energy for life at 'Lost City'
...graphic Institution's Timothy Shank analyzed water samples
"vacuumed" from around the vents. "There aren't a lot of each kind of animal, most are only a centimeter in size and have translucent or invisible shells so it's no wonder we didn't suspect the actual diversity," says Kelley, who was chief scientist ...

from soil or other habitats for testing in the laboratory. The nematodes are accurately identified and analyzed using traditional morphology (structure and function) techniques and through molecular screening, including PCR (polymerase chain reaction...
New drugs for bad bugs
...or how a drug kills bacteria. "In the past, blood samples
were taken and the serum concentration of the drug was measured and that number was used to make dosing decisions," said Derendorf, whose work is primarily funded by the pharmaceutical companies Pfizer and Sankyo. "That may not always be the right pl...
