A DNA microarray is a collection of microscopic DNA spots attached to a solid surface. Scientists use DNA microarrays to measure the expression levels of large numbers of genes simultaneously or to genotype multiple regions of a genome. When a gene is expressed in a cell, it generates messenger RNA (mRNA). Overexpressed genes generate more mRNA ...
The bee genome contains versions of some important mammalian genes. The complete genome of Apis mellifera has been sequenced and consists of 10,000 genes with approximately 236 million base pairs. The size of the genome is a tenth of the human genome. [2] The Western honey bee gene sequence showed 163 chemical receptors for smell but only 10 ...

Natural computing, [1] [2] also called natural computation, is a terminology introduced to encompass three classes of methods: 1) those that take inspiration from nature for the development of novel problem-solving techniques; 2) those that are based on the use of computers to synthesize natural phenomena; and 3) those that employ natural materials (e.g., molecules) to compute.
A Florida woman who allegedly snatched a three-year-old boy from his fenced-in yard and ran off down the street last week told the cops she shouldn’t be arrested because she “gave it back ...
Swarming is a honey bee colony's natural means of reproduction.In the process of swarming, a single colony splits into two or more distinct colonies. [1]Swarming is mainly a spring phenomenon, usually within a two- or three-week period depending on the locale, but occasional swarms can happen throughout the producing season.
The New York Times' recent game, "Strands," is becoming more and more popular as another daily activity fans can find on the NYT website and app. With daily themes and "spangrams" to discover ...
