Most estimates of the mortality risk posed by asteroid impacts put it at about the same risk as flying in a commercial airliner. However, you have to remember that this is like the entire human race riding the plane - it is one of the few risks that really could wipe us all out.
Under Reagan's policies, inflation and nominal GNP growth shriveled much faster than predicted, throwing off government revenue estimates and resulting in budget deficits.
In the 1990s, Islamists in Algeria won elections like the Brotherhood did in Egypt. The Algerian military refused to allow the Islamists to take power. A war erupted, killing between 100,000 to 200,000 people, depending on which estimates are to be believed.
We have tried to change regimes through a variety of means - over 80 times, by some estimates. Many of these efforts were counterproductive to U.S. interests.
Before the Human Genome Project, most scientists assumed, based on our complex brains and behaviors, that humans must have around 100,000 genes; some estimates went as high as 150,000.
While the Environmental Genome Project does not seek to assign allele frequencies, we are aware of the importance of accurate allele frequency estimates for future epidemiologic studies and the large sample sizes such estimates will require.
The fear of vomiting, which for me is one of the most original and most acute of my fears, is actually fairly common. Emetophobia, it's called, and by some estimates, it's the fifth most common specific phobia.
Estimates are that at least 70 per cent of all stars are accompanied by planets, and since the latter can occur in systems rather than as individuals (think of our own solar system), the number of planets in the Milky Way galaxy is of order one trillion.
By some estimates, 80% of rap music is bought by white youth. And this makes for another irony. The blooming of white alienation has brought us the first generation of black entrepreneurs with wide-open access to the American mainstream.
Between 2000 and 2010, malaria mortality rates fell by 26 percent around the world. According to the latest World Health Organization estimates, there were about 219 million cases of malaria in 2010 and an estimated 660,000 deaths.
