How mutants save a species

There's one obvious reason why it's easier for a species to survive a gradual environmental change than a sudden one: more individuals stay alive when change is gradual or moderate, meaning there are more chances for a winning mutation to emerge.

Evolution 'surprisingly predictable', says team

Scientists have shown that similar - or even identical - mutations can take place in completely separate populations of E. coli evolving in different environments over more than 1,000 generations.

Team gives ancient life another chance to evolve

Researchers at the Georgia Institute of Technology are attempting to repeat the path of evolution by taking a gene from an ancient organism and watching it evolve.

Re-programmable cells to create new life forms

An international team of scientists has embarked on an ambitious research project to develop an in vivo biological cell that can be reprogrammed like a computer operating system.

NAND gate built from bacteria

Scientists have taken another step towards biological computing, with the creation of logic gates from gut bacteria and DNA.

Team develops tools to edit DNA

MIT and Harvard researchers say they can edit the genetic code of a living cell, allowing them to give cells new functions such as building proteins not found in nature, or engineering bacteria that are resistant to any viral infection.

Team builds logic gates into bacteria

A team at the University of California has successfuly implanted E coli bacteria with the key molecular circuitry to act as computers.
