of chemicals that runs into lakes and streams in the Mississippi watershed ?an area encompassing about 40 percent of the United States ?ultimately turn more than 7,000 square miles of the Gulf of Mexico into a "dead zone," a condition known as hypoxi...
Studies reveal how plague disables immune system, and how to exploit the process to make a vaccine
... respond to a bacterial invasion. Their role is to rush
to the infection site, engulf the bacteria, chew them up into smaller pieces and present those pieces to the T and B cells -- the "adaptive" immune system -- which enter the fray more slowly but bring powerful and very specific weapons targeted at th...
Discovery of T-cell 'traffic control' boosts new drug promise
...such as FTY720 controls S1P function and slows the rush
of T cells to the transplantation site without blo... natural binding partners -- prompt the T cells to rush
into lymph nodes. But S1P, they found, can act through its own G-coupled receptors to prevent chemok...
Scientists map one of biology's critical light-sensing structures
...to guide their development. It will likely spur a rush
by scientists to capitalize on the new knowledge and may one day lead to such things as plants whose growth, flowering and death can be precisely manipulated. "We can now start changing how phytochromes work in a rational way to improve how plants r...
World faces challenge as life expectancies lengthen, scientist says
... it's necessary to look the implications before we rush
in--at least so we can prepare ourselves. We need to confront the prospect of inequality head-on, instead of waiting 10 years and then saying, 'What a surprise!'"...
'Dead zone' summer killed billions of ocean state mussels

can cause algae blooms. When the algae dies, it sinks to the bottom, where it is consumed by bacteria ?along with dissolved oxygen. This is what happened in Narragansett Bay in the summer of 2001 and again in the summer of 2003. Mussels, however, ca...

Gene chip technology shows potential for identifying life-threatening blood infection
...ethal spread, doctors who suspect sepsis typically rush
to prescribe powerful antibiotics, even before laboratory tests can confirm the diagnosis. But this practice invariably leads to the inappropriate treatment of many patients who have life-threatening, uncontrollable inflammation without an underlying...
