Rapid evolution in fish: Genomic changes within a generation

Researchers from Basel have identified the genetic basis of rapid adaptation using a native fish species. They compared threespine stickleback fish from different habitats in the Lake Constance region. Their study reveals ...

Laser-powered rover to explore moon's dark shadows

A laser light shone through the dark could power robotic exploration of the most tantalizing locations in our solar system: the permanently-shadowed craters around the moon's poles, believed to be rich in water ice and other ...

Making terahertz waves: Why liquids prefer long optical pulses

Laser-induced ionization in matter—gas, cluster, liquid, and solid—occurs when a laser pulse with sufficient intensity is focused into a target material, creating electrons and ions through nonlinear processes of laser-matter ...

Generation

Generation (from the Latin generāre, meaning "to beget"), also known as procreation in biological sciences, is the act of producing offspring. In a more general sense, it can also refer to the act of creating something inanimate such as ideas, sound, electrical generation using technology or cryptographic code generation.

A generation can refer to stages of successive improvement in the development of a technology such as the internal combustion engine, or successive iterations of products with planned obsolescence, such as video game consoles or mobile phones.

In biology, the process by which populations of organisms pass on advantageous traits from generation to generation is known as evolution.
