The genome work also shed additional light on how this diatom species uses fats, or lipids, that it is known to store in huge amounts.

The bioconcentration of PCBs in Great Lakes fish has led to widespread consumption advisories issued by both the EPA and Environment Canada.

... fission yeast." The scientists found that the DNA surrounding many late-firing origins contains repeats of a 10-basepair sequence that is rich in the nucleic acid component, guanine. Yompakdee and Huberman named these repeats "Late Consensus Sequences" (LCS). They found that one copy of an LCS produced no detec...A long-necked sea predator from China described in Science

After as much as two days of amplexus, the female will lay a clutch of eggs, which are immediately fertilized by the male. During this time, however, various males typically follow ...Gene expression in liver tumors and patient prognosis

They isolated total RNA to derive complementary DNA and characterized each sample's gene expression profile. They applied three independent approaches for data analysis to uncover subclasses of HCC and the ...Lecture on ecology of infectious diseases
