Kamenyeva said the movie "shows an efficient innate immune reaction in the lymph node, which typically has been studied for the development of adaptive immune response." The action was captured using a two-photon microscope, equipped with an L25.0 x 0.95 water immersion objective.In , Nikon Instruments said the movie won first place because it demonstrated the delicate balance between science and art. "Dr. Kamenyeva's image is the perfect combination of cutting-edge science with aesthetics that we look for in Small World, to help raise the profile of science with scientists and non-scientists alike," said Eric Flem, communications manager for Nikon Instruments.Nikon has been running its Small World contest for photomicrography since 1975, but this is only the second go-round for the "Small World in Motion" video competition. That just shows how quickly time-lapse photography has taken hold in scientific microscopy.Sperm from two males compete within reproductive tract of a female fruit fly.Second-place honors went to Stefan L pold, a biologist at Syracuse University, for a movie showing sperm from two different male fruit flies competing within the reproductive tract of a fem <a href={url}>{keyword}</a> ale fly. In the 400x time-lapse video, the sperm c <a href={url}>{keyword}</a> ells look like red and green worms scurrying through a complex network of tunnels."Competition between sperm is a widespread phenomenon throughout the animal kingdom and a powerful evolutionary force driving species diversity," . "However, it has been nearly impossible to study the fundamental biological processes associated with such sperm competition, occurring whenever sperm from different males mix inside of females. The very recent development of genetically modified fruit flies that produce sperm with either green- or red-fluorescent heads (as seen in the movie) is now allowing us to answer important biological questions."Nils Lindström's video <a href={url}>{keyword}</a> shows the development of a kidney.
