More and more political analysts and weak-kneed politicians are advising the historically pro-life Republican Party to abandon its pro-life stance for political gain. My first response is that if you cannot trust a party on the value of defending human life how can you trust it on issues like marginal tax rates?

I always have issues with trust.

I travel Europe every couple of weeks. I just came back from London Holland and Denmark. Every nation on this planet has its issues with race and I am not sure if everyone has figured out how to deal with it.

My job is to be a spokesman - the spokesman I suppose - for the President for the White House to do the daily briefings to manage the press corps in terms of travel day-to-day needs access interviews all those issues.

I am in the process of trying to decide whether I can make a substantive and productive contribution to the policy-making process. I was always there because I wanted to work on the pressing issues of the day - I'm interested in energy I'm interested in the climate bill and technology policy.

IBM's long-standing mantra is 'Think.' What has always made IBM a fascinating and compelling place for me is the passion of the company and its people to apply technology and scientific thinking to major societal issues.

Protein engineering is a technology of molecular machines - of molecular machines that are part of replicators - and so it comes from an area that already raises some of the issues that nanotechnology will raise.

I absolutely believe that a lot of the issues raised in 'Amped' about technology migrating into our bodies are issues that we're really going to deal with soon.

We shouldn't build a technology to colour or grey out what people say. The media in general is balanced although there are a lot of issues to be addressed that the media rightly pick up on.
