Here is Craig Venter announcing the successful self-replication of a cell with an entirely synthetic genome:
This is one of the biggest news stories of the year, and time will tell what its implications are. It has been extensively covered in the media, and will surely be a part of school ethics discussions for years to come.The full Science paper is online here.

Where’s the money in Biology? Probably where the future lies – genetics and synthetic biology.
As we learn more about genomes and the way different organisms (including pathogens) work, we can move towards creating targeted responses and DNA-level manipulation. Synthetic biologists take DNA and try to re-work it into a solution to a problem – by creating synthetic DNA, they hope to achieve control over the functions of the organism. They hope to generate alternative sources of fuel, targeted treatments and vaccines and many more applications.
BioBricks (company link) are a leading example of synthetic biology in action. Think of them like lego bricks or parts of standard computer code – you can take them and (theoretically) fit them into any genome. This is one of the wonders of DNA – base-pairings and the universality of the genetic code allow these researchers endless opportunities for tinkering and advancing science. Some BioBricks are ‘parts’, some are ‘devices’ and others are ‘systems’ – sections of code that increase in complexity and functionality.
There is an exciting world of information out there about this topic, and it’s well worth looking at if you think your future lies in biotechnology. It’s a discipline that pulls together Biology, Physics, Chemistry, Maths, Engineering and Programming, and the ways in are various. If you want to find out more about a career in synthetic biology, MIT are world-leaders in the field.
