Device that rapidly detects nerve agents named one of 'greatest army inventions' for 2003
.... If contamination is detected, within seconds the sponge
changes color from yellow to red. Beyond its high sensitivity to nerve agents, the Nerve Agent Sensor also is resistant to environmental factors, such as high temperatures, and interference from other compounds. It has a two- to three-year shelf lif...

to remove serotonin once it is released, and therefore stops its actions. Because the transporter is diminished in IBS, serotonin stays around longer, and this can lead to changes in motility, secretion and sensitivity." The study examined tissue obt...
