Using just a camera, a few drops of water, and some editing software, Nakamura created a completely believable rendition of one of the most complex of natural phenomena.
Animal venoms are among the most complex biochemical natural secretions known and comprise a mixture of bioactive compounds often referred to as toxins (Norton and Olivera 2006; Vonk et al. 2013; von Reumont et al. 2014).
A5 Health workers from scores of volunteer organizations and government agencies have taken actions to respond rapidly to any rumor of health problems, in the largest and most complex response ever to a natural disaster.
Not only is it "one of the most complex symbiotic interactions in the natural world," as Oldroyd puts it, but it's also one of the major ways of getting nitrogen into living systems.
Filled with spermaceti oil (early hunters believed to be the animal's semen, hence its name), it functions as the natural world's most complex sound generator.
Natural selection, like most complex scientific theories, runs counter to common experience and therefore competes usually unsuccessfully with intuitive ideas about inheritance, variation, function, intentionality, and probability.
Seminal progress and, arguably, the dawn of the current golden age of microbiology came from PCR amplifying and sequencing the gene encoding the small ribosomal RNA subunit from complex, natural microbial communities, most members of which were recalcitrant to cultivation-dependent microbiological approaches (Olsen et al. 1994).
The bed resistance is one of the most complex aspects of water flow studies in natural streams.
Understanding how the human visual system recognizes complex natural images is a most important but challenging problem in vision science.
