...sequence the 3.1 billion chemical "letters" that make up human DNA, the harder task may be to figure out what they mean. Trying to determine what's going on in a particular cell--which contains the entire complement of 30,000 or so genes but uses only a small fraction of them--is like watching a full-length movie a few pixels at a time...
...notes in Diversity that the 1.5 million species named so far by scientists represent only a tiny fraction of the tens of millions that may be out there. Wilson's prediction that 30% to 50% of all species would be extinct by the middle of the 21st century was meant to provoke--and it did. Critics rejected the estimate as another one of his flamboyant speculations. But subsequent research has supported it. From the perspective of the biodiversity scientist, virtually all the signs...

The atmosphere there was indeed inspiring -thousands of people prepared to shield with their bodies their last hope for change. Yet these many thousand people were a tiny fraction of the city's population, And there were few such demonstrations in other cities and towns across the USSR. Most people were sitting and waiting. Would the military have moved against the White House if someone had given the order? Some would have, I think. Not all, but enough to break...
...value of the world's electrical power generated from renewable sources such as wind and solar is about $7 billion--up from less than $1 billion a decade ago, but still a tiny fraction of the total electricity market, according to a study by green-technology consultants Clean Edge, of Oakland, Calif. That study projects the renewable market to reach $82 billion by 2010, as technological advances lower the price and make renewables easier to use. And governments around the world are pushing power producers to reduce emissions that contribute to air pollution and global warming. Joel Makower, co-founder...
...tiny fraction of that throng gathered last Thursday night outside the Belgrade prison where Milosevic had been held since April, chanting "Slobo, Slobo, we will never abandon you." Milosevic's wife Mira and his daughter-in-law Milica Gajic were there, too, waiting silently in a green...
