BEIJING, March 29 (Xinhuanet) -- Tickets for Apple's annual World Wide Developer Conference (WWDC) 2011 have already been sold out ten hours after the event was announced Monday, according to media reports.It is the first time the event sold out the same day it was announced. Last year, the conference sold out in eight days.WWDC 2011, with the tickets priced at 1599 U.S. dollars, will run from June 6 till June 10 at the Moscone West conference center in San Francisco.This year's speedy turnaround is probably because of a rumored double-focus on iOS and Mac OS."At this year's conference we are going to unveil the future of iOS and Mac OS," Philip Schiller, Apple's senior vice president of Worldwide Product Marketing, said in a press release."If you are an iOS or Mac OS X software developer, this is the event that you do not want to miss."The event will feature more than 100 technical sessions presented by Apple engineers on Application Frameworks; Graphics, Media and Games; Developer Tools; Internet and Web, and Core OS.

LOS ANGELES, April 12 (Xinhua) -- With the help of NASA Telescopes, astronomers have uncovered one of the youngest galaxies in the distant universe, with stars that formed 13.5 billion years ago, the Jet Propulsion Laboratory (JPL) announced on Tuesday.The finding addresses questions about when the first galaxies arose, and how the early universe evolved, JPL noted in a press release.Infrared data from both the Hubble Space Telescope and the post- coolant, or "warm," phase of NASA's Spitzer Space Telescope mission revealed that the galaxy's stars are quite mature, which means they must have formed when the universe was just a toddler, said JPL in Pasadena, Los Angeles.This challenges theories of how soon galaxies formed in the first years of the universe and could even help solve the mystery of how the hydrogen fog that filled the early universe was cleared, according to astronomers involved in the study.This galaxy is not the most distant ever observed, but it is one of the youngest to be observed with such clarity, JPL said.Normally, galaxies like this one are extremely faint and difficult to study, but, in this case, nature has provided the astronomers with a cosmic magnifying glass, JPL said.The galaxy's image is being magnified by the gravity of a massive cluster of galaxies parked in front of it, making it appear 11 times brighter. This phenomenon is called gravitational lensing."Without this big lens in space, we could not study galaxies this faint with currently available observing facilities," said Eiichi Egami of the University of Arizona in Tucson. "Thanks to nature, we have this great opportunity to see our universe as it was eons ago."The findings may help explain how the early universe became " reionized," according to JPL."Seeing a galaxy as it appeared near the beginning of the universe is an awe-inspiring feat enabled by innovative technology and the fortuitous effect of gravitational lensing," Jon Morse, NASA's Astrophysics Division director at the agency's headquarters in Washington, said in the release."Observations like this open a window across space and time, but more importantly, they inspire future work to one day peer at the stars that lit up the universe following the big bang."

BRASILIA, March 15 (Xinhua) -- A nationwide program aimed at providing internet access to 80 percent of the country's population by 2014 is forging ahead in Brazil, Communications Minister Paulo Bernardo said on Tuesday.The National Broadband Plan (PNBL), with participation of 13 ministries, is coordinated by Bernardo, who explained details about the project on Tuesday along with Joao Santana, president of Telebras, the state-owned enterprise responsible for managing the project.The authorities have criticized companies that offer internet service for failing to spread internet use in Brazil, offering an expensive service with prices amounting to about 50 U.S. dollars monthly, inaccessible to low-income families."We ended 2010 with 34 percent of Brazilian households with Internet access, and service is also very poor. Almost half of connections are of 256 mbps. We are out-of-date, with the aggravating circumstance that the connections are very expensive," Bernardo said.To speed up the process, the government started negotiating with concessionaire phone companies to improve the service quality and lower the price to about 30 reais (18 dollars), which would allow 80 percent of the population to access internet."During (former president) Lula da Silva's government, we developed a program to interconnect all schools with internet access, but we also want the private sector to do its share," he said.

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.
