Researchers can examine chromosomes and determine when genetic variations occurred. If a condition within a chromosome is both new and common throughout the population, then researchers assume that natural selection promoted the variation. “According to Charles Darwin's famous theory, evolution happens faster in big populations,” writes John Roach for National Geographic News. The world had...

US education experts suggest that the nation’s children fail to keep pace with the top international students. A globalizing economy means that today's kindergarten students will eventually compete for jobs or work on teams with peers from around the world.

Canada has had a similar satellite in orbit since 1995, which monitors the progress of melting polar ice, oil spills and agricultural growth. Research based on the satellite’s images contributed to Canada becoming a...

As evidence of climate change is increasingly accepted, the need to counter the phenomenon becomes more pressing. The Kyoto Protocol has been in effect since early 2005, and yet less than 800 million out of the world’s 6.6 billion people live in countries that have agreed to reduce emissions. Since then, carbon emissions continue to climb and deforestation has intensified. Without the support of...

Clocks, zero and paper – these and many other fundamental innovations emerged in Asia. Yet around the 15th century, the surge in Asian innovation tapered off. Scholars seek to explain sources for innovation and posit that leaders must provide incentives for progress; internal or external forces can give inventors a sense of purpose. Today, Asians are eager to pursue innovation through education...
