A paper plane also known as a paper airplane in American English or paper aeroplane in British English is a toy aircraft, usually a glider made out of single folded sheet of paper or paperboard. A simple nose-heavy paper plane, thrown like a dart , is also known as a paper dart. The origin of folded paper gliders is generally considered to be of Ancient China, although there is equal evidence that the refinement and development of folded gliders took place in equal measure in Japan. Certainly, manufacture of paper on a widespread scale took place in China BCE, and origami and paper folding became popular within a century of this period, approximately BCE.

As social insects living in a colony, honey bees must communicate with one another. Honey bees use movement, odor cues, and even food exchanges to share information. Honey bee workers perform a series of movements, often referred to as the "waggle dance," to teach other workers the location of food sources more than meters from the hive. Scout bees fly from the colony in search of pollen and nectar. If successful in finding good supplies of food, the scouts return to the hive and "dances" on the honeycomb.
Metrics details. Differential gene expression mechanisms ensure cellular differentiation and plasticity to shape ontogenetic and phylogenetic diversity of cell types. A key regulator of differential gene expression programs are the enhancers, the gene-distal cis -regulatory sequences that govern spatiotemporal and quantitative expression dynamics of target genes.
Metrics details. These clocks are acknowledged as a highly accurate molecular correlate of chronological age in humans and other vertebrates. Also, extensive research is aimed at their potential to quantify biological aging rates and test longevity or rejuvenating interventions.
