BEIJING, July 14 (Xinhuanet) -- European music service Spotify is set to launch in the United States on Thursday, according to media reports.The streaming service will be available in the morning by invitation and through subscription."Spotify is a new way to listen to and manage your music, discover new tracks and share songs and playlists with friends – music whenever you want it, wherever you are," the company said in a statement.Spotify's streaming music and subscription service have long been popular in Europe since its launch in late 2008, and the company has been aiming for a US launch for nearly as long.Spotify has inked agreements with Sony Corp Music Entertainment, EMI Music, and Vivendi SA's Universal Music Group in the last few months. It is expected to close a deal with Warner Music Group by launch or soon after, according to a source.

WASHINGTON, June 21 (Xinhua) -- A new study from Harvard School of Public Health (HSPH) and University of California, San Francisco, researchers suggests that men with prostate cancer who smoke increase their risk of prostate cancer recurrence and of dying from the disease. The study will be published Wednesday in the Journal of the American Medical Association."In our study, we found similar results for both prostate cancer recurrence and prostate cancer mortality," said Stacey Kenfield, lead author and a research associate in the HSPH Department of Epidemiology. "These data taken together provide further support that smoking may increase risk of prostate cancer progression."Kenfield and her colleagues conducted a prospective observational study of 5,366 men diagnosed with prostate cancer between 1986 and 2006 in the Health Professionals Follow-Up Study. The researchers documented 1,630 deaths, 524 (32 percent) due to prostate cancer, 416 (26 percent) due to cardiovascular disease, and 878 prostate cancer recurrences.The researchers found that men with prostate cancer who were current smokers had a 61 percent increased risk of dying from prostate cancer, and a 61 percent higher risk of recurrence compared with men who never smoked. Smoking was associated with a more aggressive disease at diagnosis, defined as a higher clinical stage or Gleason grade (a measure of prostate cancer severity). However, among men with non-metastatic disease at diagnosis, current smokers had an 80 percent increased risk of dying from prostate cancer.Compared with current smokers, men with prostate cancer who had quit smoking for 10 or more years, or who had quit for less than 10 years but smoked less than 20 pack-years before diagnosis, had prostate cancer mortality risk similar to men who had never smoked. Men who had quit smoking for less than 10 years and had smoked 20 or more pack-years had risks similar to current smokers."These data are exciting because there are few known ways for a man to reduce his risk of dying from prostate cancer," said senior author Edward Giovannucci, professor of nutrition and epidemiology at HSPH. "For smokers, quitting can impact their risk of dying from prostate cancer. This is another reason to not smoke."Prostate cancer is the most frequently diagnosed form of cancer diagnosed in the United States and the second leading cause of cancer death among U.S. men, affecting one in six men during their lifetime. More than two million men in the U.S. and 16 million men worldwide are prostate cancer survivors.

WASHINGTON, Sept. 15 (Xinhua) -- A team of researchers has discovered a planet that orbits around a pair of stars, the U.S. space agency NASA announced Thursday.This is the first instance of astronomers finding direct evidence of a so-called circumbinary planet. A few other planets have been suspected of orbiting around both members of a dual-star system, but the transits of the circumbinary planet have never been detected previously.The team, led by Laurance Doyle of the SETI Institute in California, used photometric data from the NASA Kepler space telescope, which monitors the brightness of 155,000 stars.NASA's Kepler mission has discovered a world where two suns set over the horizon instead of just one. The planet, called Kepler-16b, is the most "Tatooine-like" planet yet found in our galaxy. Tatooine is the name of Luke Skywalker's home world in the science fiction movie Star Wars. In this case, the planet it not thought to be habitable. It is a cold world, with a gaseous surface, but like Tatooine, it circles two stars.They found the binary star system by detecting a system where the stars eclipsed each other from the perspective of the Kepler spacecraft. These stars have two eclipses: A primary eclipse when the larger star is partially blocked by the smaller star and a secondary eclipse where the smaller star is fully blocked by the larger star.But the researchers also noticed other times when the brightness of the two stars dropped, even when they were not in an eclipse position. This pattern suggested that there was likely a third object involved. The fact that these so-called tertiary and quaternary eclipses recurred after varying intervals of time, and were of different depths, indicated that the stars were in different positions in their orbit at each instance. This result showed that the tertiary and quaternary eclipses were being caused by something circling both stars, and not an object circling one or the other star.Measurements of the variations in the timing of all four types of eclipses, resulting from the mutual gravitational interactions of the two stars and the third body, demonstrated that the third object was, indeed, a planet. Their work indicates that the planet is less massive than Jupiter, possibly comparable in mass to Saturn, and that the larger of the two binary stars is smaller than our Sun.Their findings will be published Friday in Science."This discovery confirms a new class of planetary systems that could harbor life," Kepler principal investigator William Borucki said in a statement. "Given that most stars in our galaxy are part of a binary system, this means the opportunities for life are much broader than if planets form only around single stars. This milestone discovery confirms a theory that scientists have had for decades but could not prove until now."

BEIJING, July 5 (Xinhuanet) -- Facebook CEO Mark Zuckerberg confirmed that he has signed up to Google+, the new social networking platform from Google, according to media reports Tuesday.Launched last month, Google+ is the Internet giant's latest foray into social networking.Zuckerberg confirmed that the profile with his name on Google+ belongs to him only, and said, "Why are people so surprised that I'd have a Google account?" Facebook CEO Mark Zuckerberg reacts after unveiling a new messaging system during a news conference in San Francisco, California November 15, 2010.In social networking field, it is rare for someone to join the rival's platform, therefore, Zuckerberg's move is considered strange.But interestingly, Zuckerberg has more followers than Google founders Larry Page and Sergey Brin, and even Vic Gundotra, the man behind Google+, with over 21,000 people.Besides Google+, Zuckerberg also has an account on Twitter, though it has not been updated for some time.
