... , he explained. Natural catalysts reconfigure themselves over and over again in response to different chemical cues -- as enzymes do in the body, for example.
When scientists need a catalyst of a ... Lay your eggs here
... water containers stimulate the female mosquitoes to lay their eggs. The female mosquitoes sense these chemical cues and decide that the water container is a preferable environment for their larvae to ... Observatory: Not Just Any Water Will Do for Mosquitoes
Researchers have identified some of the chemical cues in water that determine where a mosquito will choose to lay its eggs.1 missing gene leads to fruitless mating rituals
... Duke University Medical Center have discovered. Because they lack the ability to read important chemical cues, these flies will indiscriminately attempt to have sex with other males, and with females ... Scientists identify key roadblock to gene expression
... the first nucleosome the RNA polymerase encounters. "This pause is maintained until chemical signals from the cell cue the removal of the nucleosome and encourage the RNA polymerase to continue along ... Nanoparticles aid bone growth
... cells on porous, biodegradable materials called scaffolds, which act as patterns. With the right chemical and physical cues, the cells can be coaxed into producing new bone. As the scaffold degrades, ... Steroids in female mouse urine light up nose nerves of male mice
