LOS ANGELES, May 23 (Xinhua) -- NASA's Gravity Recovery And Interior Laboratory spacecraft (Grail) will begin final preparations for a launch on a Moon mission in late summer, the Jet Propulsion Laboratory (JPL) said on Monday.The dynamic duo will orbit the moon to determine the structure of the lunar interior from crust to core and to advance understanding of the thermal evolution of the moon, according to JPL in Pasadena, Los Angeles.After arriving at the Astrotech payload processing facility in Titusville, Florida last week, the Grail twins, known as Grail-A and Grail-B, were removed from their shipping containers Monday. Later this week, they will begin functional testing to verify their state of health, said JPL.The twins were shipped from Lockheed Martin Space Systems, Denver.Over the next four months at the Astrotech facility, the spacecraft will undergo final testing, fueling and packaging in the shroud that will protect them as the Delta II launch vehicle lifts them into space. The spacecraft will then be transported to the Cape Canaveral Air Force Station for installation atop the rocket that will carry them toward the moon, JPL said."We're only a few full moons away from a mission that will reveal clues not only into the history of the moon and Earth, but will provide important data for future lunar exploration," said Maria Zuber, Grail's principal investigator, based at the Massachusetts Institute of Technology.Grail will be carried into space aboard a United Launch Alliance Delta II Heavy rocket lifting off from Launch Complex-19 at the Cape Canaveral Air Force Station in Florida. The launch period opens Sept. 8, 2011, and extends through Oct. 19. For a Sept. 8 liftoff, the launch window opens at 5:37 a.m. PDT (8:37 a.m. EDT) and remains open through 6:16 a.m. PDT (9:16 a.m. EDT).Grail-A and Grail-B will fly in tandem orbits around the moon for several months to measure its gravity field in unprecedented detail.The mission will also answer longstanding questions about Earth' s moon, and provide scientists a better understanding of how Earth and other rocky planets in the solar system formed, according to JPL, which manages the Grail mission.

LOS ANGELES, April 4 (Xinhua) -- A woman's breast milk cells may be used to predict cancer in future research, according to a study published by HealthDay News on Monday.In the study, researchers at the University of Massachusetts in Amherst collected breast milk from 271 women in the United States. All had either undergone a biopsy of the breast to check for cancer, or were scheduled for one.The researchers evaluated breast milk samples from the biopsied and non-biopsied breasts.The researchers first isolated potentially cancerous cells, known as epithelial cells, and then isolated DNA to look for signals that regulate tumor suppresser genes.In the next step, the researchers analyzed three genes among the many known to undergo a process called methylation in breast cancer. Methylation in a specific region of a gene can inhibit or suppress the expression of a gene.For one gene, SFRP1, the average methylation was higher in the biopsied breast, the study found.Among the women whose biopsies detected cancer, average methylation of the RASSF1 gene in the biopsied breast was considerably higher compared to the non-biopsied breast.Among the women whose biopsies detected cancer, average methylation of the RASSF1 gene in the biopsied breast was considerably higher compared to the non-biopsied breast."It looks as if we can use the cells from breast milk to assess breast cancer risk," said Dr. Kathleen Arcaro, an associate professor of veterinary and animal sciences at the university.It's too soon, however, to assess the cancer detection rate associated with breast milk cell examination, she said."We can't say at this point for two reasons," she said. "One is, we need long-term follow-up. And the second really important reason is, we need to sample a larger panel of genes."Arcaro is to present her findings later Monday at the annual meeting of the American Association for Cancer Research in Orlando, Florida, according to HealthDay News.

CHIAYI, Feb. 26 (Xinhua) -- Chen Yunlin, the Chinese mainland chief negotiator with Taiwan, discussed cooperation prospects on Friday with fishermen and farmers in Chiayi in southern Taiwan.Chen, president of the mainland's Association for Relations Across the Taiwan Straits (ARATS), led a 50-member delegation and spoke at a seminar attended by more than 70 business people from both the mainland and Taiwan.He said small and medium-sized enterprises on both sides "played an important role in cross-Strait economic development, employment and in maintaining social stability.""Small- and medium-sized businesses are an important part of cross-Strait economic exchanges," he said, adding that among the more than 80,000 Taiwanese enterprises investing on the mainland, over 50 percent are small and medium-sized companies.Chen said that efforts should be made to enhance cooperation between small and medium-sized enterprises on the mainland and those in central and southern Taiwan.The mainland delegation arrived in Chiayi from Kaohsiung after investigating the investment environment with local business leaders. They arrived in Taipei on Wednesday at the invitation of Chiang Pin-kung, chairman of Taiwan's Straits Exchange Foundation (SEF). Both the SEF and the ARATS are authorized by the two sides to handle cross-Strait affairs.Chen said that since 2005, the mainland bought a large amount of farm and fishing products from Taiwan, which greatly boosted sales of Taiwanese products."Many renowned mainland distribution firms are present here at the seminar to seek cooperation opportunities with Taiwan's farmers and fishermen so that the sale of Taiwanese products on the mainland could increase steadily," he said.Chiang said the farming and fishing industries were the most important sectors in southern Taiwan.He added that the tax-reduction plan of the cross-Strait Economic Cooperation Framework Agreement's (ECFA) "early harvest" program, which took effect on January 1, covered 13 categories for farming products and five categories for fishing goods. Chiang said the plan was an opportunity for the industry to expand its exports to the mainland.He noted that the "early harvest" program's duty exemption also covered sectors like textiles, machinery components, and "all related to small- and medium-sized enterprises."Chiang said Friday's seminar was meant to promote cooperation between smaller businesses across the Strait, to deepen the effect of the ECFA to benefit both sides.The mainland delegation will continue its trip in southern Taiwan and return to Taipei late Saturday. They will visit Taipei's Neihu Industrial Park on Sunday before leaving the island on Monday.

CANBERRA, May 27 (Xinhua) -- An Australian student has discovered a part of the universe that astrophysicists have spent decades trying to find, Australia's Monash University on Friday confirmed in a statement.Astrophysicists have long thought the universe has a greater mass than is visible in the planets, but they had no way of proving it is there.Undergraduate student Amelia Fraser-McKelvie, 22, was on a summer internship at Monash University to learn more about astrophysics, when she managed to solve one of the big mysteries of science.Fraser-McKelvie, an aerospace engineering student, conducted a targeted X-ray search for the matter and found evidence of it within three months.Her tutor, Kevin Pimbblet, said the discovery is significant."We've been looking for this ordinary matter for a couple of decades," he said in a statement on Friday."It's been published in one of the most prestigious journals in the world, so astronomers all over the world will be able to read this article."Scientists had thought the matter would have a temperature of about 1 million degrees Celsius, 1.8 million degrees Fahrenheit, and should therefore be observable at X-ray wavelengths.Amelia Fraser-McKelvie's discovery has proved that prediction is correct, Pimbblet said.The trio published a research paper on the missing mass in one of the world's oldest and most prestigious scientific journals, Monthly Notices of the Royal Astronomical Society.He said the discovery could change the way telescopes are built.

JERUSALEM, March 31 (Xinhua) -- Two researchers at the Hebrew University (HU) of Jerusalem have been honored with a prestigious award for their study of the connection between several inflammatory diseases, cancer and bacteria.Medical faculty members, Dr. Eli Pilarsky and Prof. Sigal Ben- Yehuda, won this year's Sir Zelman Cowen Universities Fund prize that recognizes significant achievement in the field of medicine.The prize committee noted the impressive contributions of Pilarsky and Ben-Yehuda in understanding complex diseases like cancer and antibiotic-resistant infections, and, in a first, decided to award the two scientists this year.Pilarsky told Xinhua that his research deals with the connection between chronic inflammatory diseases like hepatitis, and the development of cancer cells."The relevance of this discovery is that we were able to establish the link between the molecules secreted with such inflammations and the proliferation of cancer cells," Pilarsky explained, noting that "we discovered that the inflammation favors the cancer cells' growth, and now we are trying to find a way to manipulate these molecules to stop the cancer cells from appearing. ""The importance of these findings lies in the fact that 20 percent of the world's cancer cases are attributed to inflammation processes," Pilarsky pointed out.
