CANNES, France, Nov. 3 (Xinhua) -- Chinese President Hu Jintao on Thursday urged the world's major economies to work together to promote growth and financial stability."It is imperative that we stand on a higher plane, transcend differences on specific issues, move beyond short-term considerations, and jointly seek ways to overcome the crisis and sustain development," Hu told the Group of 20 (G20) summit here."At this critical moment, the G20 must work to address the key problems, boost market confidence, defuse risks and meet challenges and promote global economic growth and financial stability," said Hu.As the premier forum for international economic cooperation, the G20 must continue to demonstrate the spirit of standing together in times of adversity and pursuing win-win cooperation, he said.The Chinese president said "the current world economic situation deserves our high attention," cautioning the global recovery is fraught with instability and uncertainty and faces growing risks and challenges.Some major economies are experiencing economic slowdown and some countries are facing acute sovereign debt problems, said Hu.He also cited volatility in the international financial markets, and high inflationary pressure in emerging markets.Hu put forward a five-point proposal on what G20 nations need to do to tide over the crisis.First, the countries should ensure growth while paying attention to balance. Given the serious risks facing the global economy and continued market volatility, ensuring growth and promoting stability should be the top priority, he said."We should introduce new and strong measures to ensure that fiscal and monetary policies are fully implemented and that funding is channeled into the real economy to boost production and employment."Second, the G20 nations should strengthen unity and send a strong signal to the world as there is widespread panic and acute lack of confidence in the markets, said Hu.He urged G20 members to strengthen consultation and coordination, tackle sovereign debt risks, regulate cross-border capital flow, put the fluctuation of commodity prices under control, mitigate global inflationary pressure and make sure that the economic policies pursued by various countries do not offset each other.Third, global economic governance should be improved through reform, Hu said.The international financial crisis has highlighted the deficiencies in the global economic governance system, said Hu."Major efforts should be made to reform and improve the international monetary system, international trading system and commodity pricing mechanism," said the Chinese president.

WASHINGTON, Dec. 7 (Xinhua) -- The use of two drugs never tried in combination before in ovarian cancer resulted in a 70 percent destruction of cancer cells already resistant to commonly used chemotherapy agents, say researchers at Mayo Clinic in Florida.Their report, published on-line Wednesday in Gynecologic Oncology, suggests that this combination, ixabepilone and sunitinib, might offer a much needed treatment option for women with advanced ovarian cancer.Neither drug is approved for use in ovarian cancer. Ixabepilone is a chemotherapy drug that, like other taxane drugs, targets the microtubules and stops dividing cells from forming a spindle. It has been approved for use in metastatic breast cancer. Sunitinib, approved for use in kidney cancer, belongs to a class of tyrosine kinase inhibitors that stops growth signals from reaching inside cancer cells.When caught at late stages, ovarian cancer is often fatal because it progressively stops responding to the chemotherapy drugs used to treat it."Women die from ovarian cancer because their tumors become resistant to chemotherapy, so a drug that might be able to reduce that resistance -- which may be what this combination of agents is doing -- would be a boon to treatment of this difficult cancer," says study coauthor Gerardo Colon-Otero.The finding also highlights the importance of the role of a molecule, RhoB, that the researchers say is activated by the drug duo. It might be a potential biomarker that may help identify patients who might benefit from such combination therapy, the researchers say.

SAN FRANCISCO, Oct. 10 (Xinhua) -- Apple announced on Monday that pre-orders of its iPhone 4S have topped 1 million in a single day, surpassing the previous single-day pre-order record of the company's smartphone.The iPhone 4S pre-orders surpassed 1 million in the first 24 hours and the previous single day pre-order record held by iPhone 4 is 600,000, according to Apple."We are blown away with the incredible customer response to iPhone 4S," Philip Schiller, Apple's senior vice president of worldwide product marketing, said in a statement."The first day pre-orders for iPhone 4S have been the most for any new product that Apple has ever launched and we are thrilled that customers love iPhone 4S as much as we do," he added.U.S., newly installed Chief Executive Officer Tim Cook takes stage to give a general introduction of Apple's products, Oct. 4, 2011. Apple Inc. last Tuesday unveils iPhone 4S, the much-anticipated latest generation of iPhone.The iPhone 4S, which looks the same as the iPhone 4 but has major hardware upgrade inside, is available for pre-order last Friday and set to first arrive in stores in the United States this Friday.So far, iPhone 4, which, according to Apple, has been sold more than the first three generations of iPhones combined, is Apple's best selling iPhone.The pre-order numbers are good news for Apple as the initial introduction of iPhone 4S last Tuesday has not lived up to the anticipation of some investors and analysts, and spurred a new wave of concerns about whether the company could keep its innovation momentum in the wake of the passing of its co-founder Steve Jobs last Wednesday.

WASHINGTON, Jan. 1 (Xinhua) -- Twin U.S. spacecraft to study the moon from crust to core put themselves into the lunar orbit on New Year's Eve and New Year's Day, the country's space agency said.The second Gravity Recovery And Interior Laboratory, or GRAIL-B, reached its lunar orbit at 5:43 p.m. EST (2243 GMT) on Sunday, according to the National Aeronautics and Space Administration (NASA).The GRAIL-A started orbiting the moon at 5 p.m. (2200 GMT) Saturday.The insertion maneuvers placed the spacecraft into a near-polar, elliptical orbit with an orbital period of approximately 11.5 hours, NASA said.Over the coming weeks, the GRAIL team will execute a series of burns with each spacecraft to reduce their orbital period to just under two hours. At the start of the science phase in March 2012, the twin GRAILs will be in a near-polar, near-circular orbit with an altitude of about 55 km."NASA greets the new year with a new mission of exploration," Administrator Charles Bolden said in a statement. "The twin GRAIL spacecraft will vastly expand our knowledge of our moon and the evolution of our own planet."During GRAIL's science mission, the two probes will transmit radio signals precisely defining the distance between them. As they fly over areas of greater and lesser gravity caused by visible features such as mountains, craters and masses hidden beneath the lunar surface, the distance between the twin spacecraft will change slightly.Scientists will translate this information into a high-resolution map of the moon's gravitational field.The data will allow scientists to understand what goes on below the lunar surface and increase knowledge of how Earth and its rocky neighbors in the inner solar system developed into the diverse worlds we see today.
