Stopping skin cancer Stat3
...University of Texas MD Anderson Cancer Center, now show
that a protein called Stat3 is required for skin cancer initiation and promotion. Stat3 is a protein that normally acts to regulate the expression several genes in the cell. Stat3, when it is improperly activated, is known to be involved in a numbe...

that prolonged "black water" patches cause water quality degradation and may cause coral death. The use of remote sensing satellites provides effective means for monitoring and predicting such events. The link between coastal runoff and black water ...

how disease is a failure of a robust system, according to the authors. "The huge progress of the las...
How an insidious mutation fools DNA replication
..."We were able to extend the replication process to show
that there were no distortions that would be detected by the polymerase. This means that the DNA would continue to replicate with this mispair, and that could potentially lead to stable incorporation of a lethal mutation," said Beese. In further anal...

...its Vif protein. GIVI scientists were the first to show
that Vif not only targets intracellular APOBEC3G for accelerated destruction, but also impairs new production of this antiviral factor. Vif's combined effects effectively overcome the antiviral action of APOBEC3G. The fact that Vif must bind to APOBE...

Study in Science reveals recreational fishing takes big bite of ocean catch

that a few fish per person times millions of fishermen can have an enormous impact." "The large impacts of recreational fisheries surprised us, and they may startle many people, including fishermen, concerned about the health of our oceans. But if an...

that the human plasminogen was functional in the mice, Sun crossed the transgenic mice with another strain in which their own plasminogen genes had been deleted. This cross essentially restored plasminogen function in the resulting mice. In test-tube...
Researchers uncover secrets of immune system's munitions factory
