WASHINGTON, Jan. 20 (Xinhua) -- Visiting Chinese President Hu Jintao on Thursday called upon the U.S. Congress to continue helping the two countries boost their relations.Pursuing a healthy and steady development of China-U.S. ties is China's established policy and strategic choice, Hu stressed in talks here with Speaker John Boehner of the House and Majority leader Harry Reid of the Senate.It has also been the consensus of the U.S. administrations, whether Republican or Democratic, since the two countries established formal diplomatic relations 32 years ago, he added.Chinese President Hu Jintao (2nd L front) meets with U.S. Senate Majority Leader Harry Reid (2nd R front) on Capitol Hill in Washington, the United States, Jan. 20, 2011Thanks to the two nations' concerted efforts, the China-U.S. relationship has been moving forward steadily, Hu said, citing the two countries' increasing cooperation and coordination on trade, terrorism, climate change, Korean Peninsula denuclearization and other bilateral, regional and global issues.A sound relationship between Beijing and Washington not only serves the fundamental interests of both peoples, but greatly contributes to the peace, stability and prosperity of the Asia-Pacific region and beyond, the Chinese president said.With China and the United States differing in culture, social system and development level, it is normal for the two sides to have differences on some issues, he said.But what matters most is the common interests of the two countries, he stressed, saying that Beijing's position is that the two sides should seek common ground while reserving differences, so as to learn from each other and pursue common prosperity on the basis of mutual respect and equality.

BEIJING, March 29 (Xinhuanet) -- A new study has found that rejection can literally hurt in the same way as physical pain does, according to media reports Tuesday.Researchers found that intense emotional pain, such as feelings of rejection after a breakup of a relationship, can trigger brain activities similar to when people suffer physical pain.The research findings were published in Tuesday's Proceedings of the National Academy of Sciences.The study followed 40 volunteers who experienced unwanted romantic breakups in the past six months, and the researchers analyzed their brain activity during two "painful" situations.The results showed that the two situations, thinking about the loss of their ex-partner and experiencing mild physical pain similar to holding a very hot coffee cup, caused response in the overlapping parts of the brain."This tells us how serious rejection can be sometimes," said study author Edward E. Smith, director of cognitive neuroscience at Columbia University. Smith added. "Our ultimate goal is to see what kind of therapeutic approach might be useful in relieving the pain of rejection."

PARIS, May 20 (Xinhua) -- Heavy-load launcher Ariane 5, carrying two communication satellites GSAT-8 and ST-2, lifted off at around 22:38 p.m. Paris time (GMT 2038) on Friday from Europe' s Spaceport in French Guiana.Built by Japan's Mitsubishi Electric Company, ST-2 will offer Ku-and C-band relay services across the Middle East, Central Asia, India and Southeast Asia to the ST-2 Satellite Ventures joint company of Singapore Telecommunications Ltd (SingTel) and Taiwan' s Chunghwa Telecom Company Ltd..With a weight around 5.1 tons at launch, ST-2 was separated first around 27 minutes after the lift-off. It has a designed life of 15 years and will function at 88 degree East.The lighter passenger GSAT-8, built by the Indian Space Research Organization (ISRO), will serve to augment India's Ku- band relay capabilities and offer aircraft navigation assistance over Indian airspace and adjoining areas with its two-channel GAGAN system.GSAT-8 was expected to be ejected off around 31 minutes into the flight and will be orbited at 55 degree East. Weighed about 3. 1 tons, it has a designed life span of at least 12 years.Arianespace started its 2011 busy year for heavy-lift Ariane 5 with the milestone launch of Europe's second Automated Transfer Vehicle (ATV) on February 16.The next launch of Ariane 5 planned to lift off two TV broadcast and telecommunications relay satellites: BSAT-3c/JCSAT- 110R for Japan's Broadcasting Satellite System Corporation (B-SAT) and SKY Perfect JSAT Corporation, and ASTRA 1N for Luxemburg-based SES company.

WASHINGTON, April 25 (Xinhua) -- A class of drugs that shows promise in breast and ovarian cancers with BRCA gene mutations could potentially benefit colorectal cancer patients with a different genetic mutation, a new study from the University of Michigan Comprehensive Cancer Center finds.Working in cell lines from colorectal cancer patients, researchers found that the class of drugs called PARP inhibitors worked against tumors with mutations in the MRE11 gene.About 15 percent of all colorectal cancers have what's called microsatellite instability, a type of error in the DNA. About 82 percent of those tumors have the MRE11 gene mutation."This is a potential broader application for PARP inhibitors, beyond breast and ovarian cancer. This is a class of drug that's already shown safety in early clinical trials and now might benefit some colorectal cancer patients as well," says lead study author Eduardo Vilar-Sanchez, a hematology/oncology fellow at the university, in a statement.The study, which was published Monday in Cancer Research, also found that PARP inhibitors are even more effective when both copies of MRE11 were mutated. Each person carries two copies of each gene, which means mutations can occur in either one or both copies. The researchers suggest that PARP inhibitors could be targeted specifically to colorectal cancer patients who have two copies of the mutated gene.Researchers are planning a phase I clinical trial to look at using PARP inhibitors in colorectal cancer patients with two mutated copies of MRE11. Future trials are being considered using PARP inhibitors to prevent colorectal cancer and other cancers in people with Lynch syndrome whose tumors have this mutation.Microsatellite instability is also seen in prostate cancer and endometrial cancer, suggesting potential for PARP inhibitors to play a role in additional types of cancer as well, Vilar-Sanchez says, adding that more research is needed in these areas.

PARIS, May 17 (Xinhua) -- Arianespace has approved the preparation review of the third Ariane 5 flight, which is expected to lift two communication satellites on Friday from the spaceport in French Guiana, the European launching center said on Tuesday.The prior readiness review approved that "Ariane 5 is now cleared for its May 19 rollout from the Final Assembly Building to the ELA-3 launch zone, where it will be readied for liftoff on Friday at 5:38 p.m. local time in French Guiana," the space center said in a statement.This dual payload flight will orbit GSAT-8 and ST-2 satellites, with a combined mass of 8,190 kilo grams.Built by Japan's Mitsubishi Electric Company, ST-2 will be utilized by the ST-2 Satellite Ventures joint company of Singapore Telecommunications Ltd (SingTel) and Taiwan's Chunghwa Telecom Company Ltd. for Ku- and C-band relay services across the Middle East, Central Asia, India and Southeast Asia.The lighter passenger GSAT-8, built by the Indian Space Research Organization (ISRO), will serve to augment India's Ku- band relay capabilities and offer aircraft navigation assistance over Indian airspace and adjoining areas with its two-channel GAGAN system.The Arianespace started its 2011 busy year for heavy-lift Ariane 5 with the milestone launch of Europe's second Automated Transfer Vehicle (ATV) on February 16, and then a dual payload on April 22 that orbited Yahsat Y1A and Intelsat New Dawn satellites.
