What you do is sometimes determined by what your neighbours do. Scientists believe that this extends to stomatal behaviour. Stomata are pores placed at the plant surface that allow gas exchange with the atmosphere. When entire plants are exposed to light, all their stomata open widely to maximize the uptake of CO2 for photosynthesis. In contrast, in the dark all the stomata remain closed to prev...Candidate research sites selected for the National Ecological Observatory Network

WASHINGTON, D.C. (May 21, 2007) Studies have shown that gastrointestinal (GI) tract function is often influenced by specific stimulants or reactors, which sometimes cause irritable bowel syndrome (IBS) or constipation. Two studies presented today at Digestive Disease Week 2007 (DDW) take a closer look at GI stimulation, including one examining the role of serotonin and reactions to certain typ...Nanocomposite labeled cancer cells can be targeted and destroyed using lasers
A nanocomposite particle can be constructed so that it has a mix of properties that would not otherwise happen in nature. By combining an organic matrix with metallic clusters that can absorb light, it is possible to incorporate such particles into cells and then destroy those targeted cells with a laser.
