WASHINGTON (CNN) -- The world's population is forecast to hit 7 billion in 2011, the vast majority of its growth coming in developing and, in many cases, the poorest nations, a report released Wednesday said.  Riders cram into a train last month in New Delhi, India. India's population is expected to be 1.7 billion by 2050. A staggering 97 percent of global growth over the next 40 years will happen in Asia, Africa, Latin America and the Caribbean, according to the Population Reference Bureau's 2009 World Population Data Sheet. "The great bulk of today's 1.2 billion youth -- nearly 90 percent -- are in developing countries," said Carl Haub, a co-author of the report. Eight in 10 of those youth live in Africa and Asia. "During the next few decades, these young people will most likely continue the current trend of moving from rural areas to cities in search of education and training opportunities, gainful employment, and adequate health care," Haub continued, calling it one of the major social questions of the next few decades. |

The planet, named WASP-17, and orbiting a star 1000 light years away, was found by the UK's WASP project in collaboration with Geneva Observatory. The discovery, which casts new light on how planetary systems form and evolve, is being announced August 12 in a paper submitted to Astrophysical Journal.

(Credit: Image courtesy of d'Errico/Vanhaeren) ScienceDaily (Aug. 27, 2009) — Shell beads newly unearthed from four sites in Morocco confirm early humans were consistently wearing and potentially trading symbolic jewelry as early as 80,000 years ago. These beads add significantly to similar finds dating back as far as 110,000 in Algeria, Morocco, Israel and South Africa, confirming these as the oldest form of personal ornaments. This crucial step towards modern culture is reported this week in the Proceedings of the National Academy of Sciences (PNAS).
