A study by Princeton researchers estimates that 8-18 million Americans may identify with more than one race in the 2000 census, several times greater than previous estimates. The vast majority of likely multiple race respondents chose 'White' when faced with the traditional single-response race question.
A new study found that Americans overestimate their lifespan by about a year compared to official statistics. Blacks and men are the most optimistic about their lifespans, while white females predict they will live less than expected.
Researchers use 'Cosmic Triangle' to plot evidence for accelerated universe expansion and high mass density of dark energy. The findings rule out models with low or negative mass density, pointing towards a flat universe dominated by dark energy.
Researchers have found that the Earth's inner core is rotating at a faster rate than its outer layers, with estimates suggesting it rotates four to 12 times slower. The independent rotation is thought to be caused by convection in the molten iron outer core, which produces the Earth's magnetic field.
