...years leading up to the human-genome work was Mycoplasma genitalium, an unlovely bacterium whose preferred target on the animals it infects is evident by its name. That organism, which the team sequenced in 1995, has one of the smallest known chromosomes of any self-replicating life-form - just 485 genes. What, Venter wondered back then, was the minimum genome an organism needed to survive and reproduce? If you could figure that out, you could determine the basic DNA chassis of all living things and then use it to design your own souped-up or dressed-down versions of life...
...just a tragedy but the single most depressing act of violence in recent times. It is, of course, a great sadness for her family and also a source of desperation for her country: if she had succeeded in elections there would have been some hope of restoring a form of democracy in Pakistan. We are now faced with turmoil in an already troubled and volatile part of the world, and since the West depends so much on Pakistan's support in the campaign against terrorism, I fear we will be subjected to a sustained campaign of violence.

Remaining addicted to fossil fuels mires the U.S. in the labyrinth of Middle East politics and keeps the country dependent upon oil-rich antagonists such as Iran and Russia. Conservatives who have jumped the fence on global warming have done so chiefly because of this issue.

"I love talking to people, doing all these town hall meetings," Clinton told reporters at Lizzard's Thicket, a breakfast joint in Columbia. He also took the opportunity to hit at his wife's opponent when he was asked: "Is Obama running against you, or Hillary Clinton, or both...
...Obama spent the day on the defensive, growing visibly frustrated at times with the Clintons. "My point was that Democrats have got to reach out to disaffected Independents and Republicans and form a working majority to move our agenda forward," Obama told supporters in Lexington yesterday. "Well, this suddenly became a situation where I was claiming that the Republicans had all the good ideas since 1980, according to the Clintons...
