It's not a small world after all: world population will soar
By Will Dunham WASHINGTON (Reuters) - Contrary to some earlier projections, the world's population will soar through the end of the 21st century thanks largely to sub-Saharan Africa's higher-than-expected birth rates, United Nations and other population experts said on Thursday. There is an 80 percent likelihood that the number of people on the planet, currently 7.2 billion, will increase to between 9.6 billion and 12.3 billion by 2100, the researchers said. They also saw an 80 percent probability that Africa's population will rise to between 3.5 billion and 5. ...

India's Mars mission enters last lap; faces crucial test on September 24
By Aditya Kalra NEW DELHI (Reuters) - India's first mission to Mars will attempt to put a spacecraft in orbit around the red planet next week, in a crucial test of a low-cost project carrying the country's hopes to join the leaders of a global space race. A successful outcome for the $74-million mission would stiffen Prime Minister Narendra Modi's resolve to build new space launch facilities capable of handling heavier satellites, to make India a stronger player in the space technology market. ...

Boeing's 'space taxi' includes seat for a tourist
By Irene Klotz CAPE CANAVERAL Fla. (Reuters) - Boeing Co's proposal to develop a so-called space taxi for NASA astronauts includes a seat for paying tourists to fly to the International Space Station, the company's program manager said on Wednesday, a first for a U.S. space program. The $4.2 billion, five-year contract allows Boeing to sell rides to tourists, Boeing Commercial Crew Program Manager John Mulholland told Reuters, adding that the price would be competitive with what the Russian space agency now charges to fly tourists to the orbital outpost. ...

Genetic history of modern Europeans a tangled tale, research finds
By Will Dunham WASHINGTON (Reuters) - The genetic origins of modern Europeans may be more complicated than previously thought. Ancient people from Siberia who were related to the first humans to enter the Americas during the Ice Age also mingled with prehistoric populations in Europe and left their mark on the DNA of today's Europeans, scientists said on Wednesday. Their study, published in the journal Nature, is the latest to use sophisticated genetic research to clarify the ancestry of modern populations. Experts had thought today's Europeans descended from two other groups of people. ...

Toronto Mayor's Rare Cancer: What Is Pleomorphic Liposarcoma?
Toronto Mayor Rob Ford has been diagnosed with an extremely rare and fast-growing cancer, called pleomorphic liposarcoma, one of his doctors announced yesterday (Sept. 17). Dr. Zane Cohen, one of the physicians treating Ford, said the tumor is about 2 to 3 years old, and described it as "very rare" and "very difficult," according to the Associated Press. The cancer is spreading and the mayor will soon receive intensive chemotherapy, said Cohen, who is a colorectal surgeon at Mount Sinai Hospital in Toronto. Liposarcoma is one type of "sarcoma," which are cancers that arise from soft tissue such as fat, joints, muscle, nerves or blood vessels.

New Mega-Telescope Will Soon Rise in Chile's Andes Mountains
A gigantic telescope designed to help astronomers solve some of the universe's deepest mysteries will soon start taking shape atop an arid mountain in the Chilean Andes. The Giant Magellan Telescope (GMT) completed several major external reviews earlier this year and is on target to enter the construction phase before the end of 2014, project representatives said. "The group here on the project is basically anticipating that we will begin construction activities late this year," GMT director Patrick McCarthy told Space.com. Scientists will use the enormous telescope to probe the nature of mysterious dark energyand dark matter, find and characterize exoplanets and study how the universe's first stars and galaxies came together, GMT representatives have said.

NASA's Second Shuttle Carrier Jet Lands on Public Display
For the second time this year, a NASA jumbo jet used to ferry space shuttles across the country has been moved for public display. The younger of NASA's two modified-Boeing 747 Shuttle Carrier Aircraft (SCA), known by its tail number N911NA, or NASA 911, was towed three-quarters of a mile(1.2 km) on Friday (Sept. 12) from an aircraft operations facility to the Joe Davies Heritage Airpark in Palmdale, California. NASA 911 will now join the Airpark's other displays available to the public Friday to Sunday weekly. It flew a total of 386 flights as a Shuttle Carrier Aircraft, 66 of which were ferry flights with a space shuttle orbiter mounted atop its fuselage.
