LOS ANGELES, May 12 (Xinhua) -- A subsurface ocean of molten or partially molten magma exists beneath the surface of Jupiter's volcanic moon Io, the Jet Propulsion Laboratory (JPL) said on Thursday."The finding heralds the first direct confirmation of this kind of magma layer at Io and explains why the moon is the most volcanic object known in the solar system," JPL said in a press release posted on its website.The finding was based on new data analysis from NASA's Galileo spacecraft, said JPL.The research was conducted by scientists at the University of California, Los Angeles; the University of California, Santa Cruz;, and the University of Michigan, Ann Arbor. The study is published this week in the journal Science, JPL said."Scientists are excited we finally understand where Io's magma is coming from and have an explanation for some of the mysterious signatures we saw in some of the Galileo's magnetic field data," said Krishan Khurana, lead author of the study and former co- investigator on Galileo's magnetometer team at UCLA."It turns out Io was continually giving off a 'sounding signal' in Jupiter's rotating magnetic field that matched what would be expected from molten or partially molten rocks deep beneath the surface."Io produces about 100 times more lava each year than all the volcanoes on Earth, according to data released by JPL in Pasadena, Los Angeles.While Earth's volcanoes occur in localized hotspots like the "Ring of Fire" around the Pacific Ocean, Io's volcanoes are distributed all over its surface, JPL said, adding that a global magma ocean about 30 to 50 km beneath Io's crust helps explain the moon's activity."It has been suggested that both the Earth and its moon may have had similar magma oceans billions of years ago at the time of their formation, but they have long since cooled," said Torrence Johnson, a former Galileo project scientist based at JPL, an affiliation with NASA."Io's volcanism informs us how volcanoes work and provides a window in time to styles of volcanic activity that may have occurred on the Earth and moon during their earliest history," said Johnson, who was not directly involved in the study.NASA's Voyager spacecraft discovered Io's volcanoes in 1979, making that moon the only body in the solar system other than Earth known to have active magma volcanoes. The energy for the volcanic activity comes from the squeezing and stretching of the moon by Jupiter's gravity as Io orbits the largest planet in the solar system.Galileo was launched in 1989 and began orbiting Jupiter in 1995. Unexplained signatures appeared in magnetic field data from Galileo flybys of Io in October 1999 and February 2000. After a successful mission, the spacecraft was intentionally sent into Jupiter's atmosphere in 2003.

BEIJING, April 10 (Xinhua) -- While advocating Internet freedom worldwide, the U.S. imposes fairly strict restriction on cyberspace on its own territory, said the Human Rights Record of the United States in 2010 issued by the Information Office of China's State Council Sunday.The United States applies double standards on Internet freedom by requesting unrestricted "Internet freedom" in other countries, which becomes an important diplomatic tool for the U.S. to impose pressure and seek hegemony, and imposing strict restriction within its own territory, the report said.According to the report, on June 24, 2010, the U.S. Senate Committee on Homeland Security and Governmental Affairs approved the Protecting Cyberspace as a National Asset Act, which will give the federal government "absolute power" to shut down the Internet under a declared national emergency.

LJUBLJANA, April 12 (Xinhua)-- Slovenian surgeons have successfully developed a new method of breast reconstruction for cancer patients, the Slovenian Press Agency (STA) reported on Tuesday.Surgeons in Ljubljana Central Hospital use a three-dimensional mould to form a new breast from the patient's abdominal fat, and then have the tissue implanted and fixated in the place of the removed breast.The mould making technique, developed by the Ljubljana Faculty of Mechanical Engineering, uses a laser to make an exact imprint of the healthy breast, which is then used to make a mirror-image three-dimensional mould for the reconstruction.That is the first in the world to help woman patients overcome embarrassment of losing their breast after mastectomy, according to the report.Speaking of the effect of the treatment, Uros Ahcan, head of plastic surgery ward in Ljubljana Central Hospital , said that the reconstructed breast is as symmetrical as possible with the healthy breast.The latest breast reconstruction method has an advantage over artificial implants, because a breast reconstructed from adipose tissue grows and shrinks in case of weight gain and weight loss. In addition, the tissue has the same temperature as the rest of the body, the STA quoted Ahcan as saying.The Ljubljana Central Hospital have done eight breast reconstruction operations for cancer patients, all of them were successful, with ten more planned in the coming weeks, the report added.Some 1,200 Slovenian women are reportedly diagnosed with breast cancer annually. About 70 percent of the patients hope to have breast reconstruction after mastectomy.

UNITED NATIONS, Jan. 26 (Xinhua) -- China on Wednesday welcomed the smooth development of the south Sudan referendum, voicing its hope that the parties in south and north Sudan could reach a consensus at an early date on the outstanding issues through dialogue and consultations.Li Baodong, the Chinese permanent representative to the United Nations, made the statement in an interview with Xinhua after he spoke at the UN Security Council about the Chinese stance on the situation of Sudan.Earlier on Wednesday, the Security Council met to hear briefings from Atul Khare, UN assistant secretary-general for peacekeeping operations, and Ibrahim Gambari, the joint special representative of the African Union-United Nations Mission in Darfur (UNAMID), on the current situation in Sudan."China welcomes the smooth development of the south Sudan referendum, this is the result of the joint efforts of north and south Sudan and the international community," Li said."At present, priority should be given to the following work: First, continuous efforts should be made to fully maintain peace and stability in Sudan to enable the country to realize its long- term peace, stability and development," he said. "Second, efforts should be made to encourage the parties in south and north Sudan to continue their efforts for the full implementation of the Comprehensive Peace Agreement (CPA), particularly for a consensus at an early date on the outstanding issues."The referendum, with its week-long polling period ending on Jan. 15, will determine whether south Sudan remains a part of Sudan or becomes independent, in accordance with the 2005 CPA that ended a long-running north-south civil war.The referendum's preliminary results are expected to be announced by Feb. 2, and depending on whether appeals are launched in the courts, the final result will be declared on Feb. 7 or 14.

BEIJING, Jan. 30 (Xinhua) -- China hoped Egypt could restore social stability and normal order at an early date, Foreign Ministry spokesman Hong Lei said Sunday."China has been closely watching the development of the situation in Egypt," Hong said when asked to comment on the ongoing turmoil in the country."Egypt is a friendly country with China, and we hope Egypt could restore social stability and normal order at an early date," he said.
