UFO closes Chinese airport

An airport in Baotou, Inner Mongolia, was forced to shut to prevent passenger jets crashing into a UFO, according to reports.

Three flights to Baotou from Shanghai and Beijing were reportedly forced to circle the airport until the UFO disappeared.

Two other flights were diverted away from Baotou and to the nearby cities of Ordos and Taiyuan. The airport was shut for around an hour "to guarantee safety" according to a spokesman.

Witnesses reported a bright light shining in the sky on September 11 around two-and-a-half miles away from Baotou airport, before suddenly vanishing.

The incident was the eighth reported UFO sighting in China since the end of June.

Xiaoshan International airport near the eastern city of Hangzhou was shut down on July 8 because of a UFO, although officials later confirmed the object sighted above the airport had been part of a military test at a nearby airbase.

In the far-western province of Xinjiang, another sighting on June 30 is thought to have been a missile test.

A number of sightings in Sichuan province may also be linked to the local custom of flying illuminated kites at night.

Robert Edwards Wins Nobel Prize in Medicine or Physiology

Edwards' work with Patrick Steptoe resulted in the first birth of a test-tube baby--Louise Brown in 1978

Prize in Physiology or Medicine for his pioneering work with in vitro fertilization (IVF), the Nobel committee announced Monday. The procedure allows a human egg to be fertilized outside of the body and then reintroduced to the female. It can now be completed with just a single implantation, thus avoiding multiple births.

Edwards, a professor emeritus at Cambridge University, began research on the problem of infertility in the 1950s. The first "test-tube baby," Louise Brown, was born in 1978, an event that the Nobel expert panel called "a paradigm shift." Since then, approximately 4 million babies have been born worldwide via IVF, many of whom now have children of their own.

Some studies have investigated whether IVF children are at a higher risk for rare diseases and malformations, but the Nobel Committee asserted that IVF babies are just as healthy as those who are naturally conceived, in a press conference Monday morning held in Stockholm. Edwards had not been predicted on an annual short list offered by Reuters for Nobel predictions. He had, however, received the 2001 Lasker Award, a medical research prize that has often preceded a Nobel.

Gliese 581 G : Is Life Possible On New Discovered Planet 2010

Gliese 581 G : Is Life Possible On New Discovered Planet 2010  – A planet has been found around the red dwarf star Gliese 581 that may possibly be hospitable to life, such as it is on earth. The planet appears to be three times the mass of earth, according a team at the University of California (UC) and the Carnegie Institution of Washington.

The planet is inside an area known as the habitable or Goldilocks zone. This is the first time a planet in such a zone has been found, and it comes after almost 500 other planets have been discovered outside of earth’s solar system.

Steven Vogt, UC professor of astronomy and astrophysics, said: “Personally, given the ubiquity and propensity of life to flourish wherever it can, I would say that the chances for life on this planet are 100%. I have almost no doubt about it.”

“We had planets on both sides of the habitable zone – one too hot and one too cold – and now we have one in the middle that’s just right,” Professor Vogt said.

“The fact that we were able to detect this planet so quickly and so nearby tells us that planets like this must be really common.”

The planet has the name Gliese 581 G, is 20 light-years away – or 120 trillion miles – from Earth in the constellation Libra. So, it’s still a long way away, and any human arriving on this planet will take many more years to achieve.
