The artificial red cell booster, EPO, hit endurance sports in the 1990s.

FORBES: The Trillion Dollar IQ Business

The potential applications for medical science are impressive enough, but consider this additional benefit: since the droplets contain no genetic material, scientists can completely sidestep all the ethical red tape surrounding the alternative stem cell approach to artificial tissue.

ENGADGET: Oxford University researchers create new 3D printed 'soft material' that could replace human tissue

By changing the composition of the dye, G24's engineers ensure that the maximum sensitivity of the cell coincides with whatever frequency mix is appropriate for the artificial light concerned.

ECONOMIST: A new type of cell may bring ��solar�� energy indoors

Though the artificial Golgi Dr Linhardt and his team have designed is much bigger than a cell, it is still small by the standards of human engineering, being built on what is known as a digital-fluidics chip.

ECONOMIST: An attempt to mimic part of a cell on a chip

This is an artificial molecule that binds to and disables the molecular messengers a gene sends out into the cell it inhabits, to tell that cell how to make the protein that the gene encodes.

ECONOMIST: A virus has been subverted into helping its host

In a conference room next door Jerry Jr. pored over a geologic map of a ski resort the Falwells plan to build on Candlers Mountain, cell phone pressed to his ear as he debated with a real estate partner whether to use artificial snow for the slopes.

FORBES: Prophets of Boom

The Vatican has over recent decades issued blanket condemnations of artificial methods of birth control, in-vitro fertilization, therapeutic and reproductive cloning, and human embryonic stem cell research.
