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, March 21 (Xinhuanet) -- A new device is being developed by American engineers to ease pain of blood sugar testing in diabetics, according to foreign media report last week.The upcoming device is the research target of a team of engineers at Arizona State University. It is specifically designed for patients with type1diabetes and type2 diabetes, according to a report in the "Journal of Diabetes Science and Technology,"  The traditional method of testing blood sugar levels involves painful pricks on the fingers to draw blood for testing. The inconvenient and painful process may somehow leave diabetics lax in their testing. The blood sugar levels, when poorly controlled, are very likely to trigger complications including heart disease, kidney disease and retinopathy.Unlike the old testing method, the new device could help people keep track of their blood sugar levels without the need to break the skin. It draws tears to measures the blood sugar levels in the fluid and gives just an accurate reading of blood sugar levels. "This new technology might encourage patients to check their blood sugars more often, which could lead to better control of their diabetes by a simple touch to the eye." said Jeffrey T. LaBelle, developer of the device.The new testing device has drawn great interest from investors due to its promising prospects. However, it still awaits a significant amount of testing before it can hit the market.

BEIJING, Feb. 8 (Xinhua) -- China's aviation authorities announced on Tuesday that more passengers traveled by air during the Spring Festival holidays, with Chinese airlines handling some 5.07 million passengers during the period.The number of passengers on flights during the Chinese Lunar New Year holidays, which ended Tuesday, was up 6 percent from the same period last year, according to the Civil Aviation Administration of China (CAAC).On average, 72 percent of the seats on flights across the country were loaded during the holiday travel season, up 2 percentage points from the same period last year, according to the CAAC.To prepare for the holiday travel surge, the CAAC arranged 38,992 flights during the holidays, including eight chartered flights to Egypt to fly home 1,796 Chinese travelers stranded amid massive protests in the African country.

BEIJING, March 14 (Xinhuanet) – "Angry Birds" game developers at Rovio have announced a funding of 42 million U.S. dollars to expand their "mean pigs, cranky birds" empire, according to foreign media report Sunday.The funding, announced Thursday, is the first venture-capital money Rovio has secured. Richard Wong with Accel Partners, who led the firm's investment in Rovio, hailed "Angry Birds" as "an incredible consumer franchise beyond just being a mobile game."With the newly raised funding, "Angry Birds" developers have made a strategic plan to achieve the brand growth of "Angry Birds."According to developer Peter "Mighty Eagle" Vesterbacka, Rovio is going to expand the franchise of "Angry Birds" in a lot of directions such as movie, broadcast and TV."We are working on a game that will involve Facebook ... really the plan is to make "Angry Birds" playable everywhere," said Vesterbacka. Besides its efforts in digital realm, Rivio is also exploring the potential toy market. Ravio has already sold over two million "Angry Birds" plush toys, which have broken into the mainstream retail channels. Recently Ravio has also branched out into selling "Angry Bird" apparel."Angry Birds", hatched in 2009, has dominated Apple's list of top-selling iPhone apps since it took flight last year. It is now available on many other platforms -- iPad, Android, iTouch, and almost every other smartphone out there.The game became world-polupar as it is easy to pick up and very addictive. Rovio, a mobile game development studio founded in Finland in 2003, enjoys the reputation as one of the most innovative game shops in Europe.

BERLIN, May 26 (Xinhua) -- German health officials said Thursday that cucumbers imported from Spain was one source of a recent deadly E. coli outbreak in northern states that killed three people and made hundreds sick.The Hamburg Institute for Hygiene and the Environment (HU) found that four cucumbers in a local market were contaminated by Enterohaemorrhagic E. coli (EHEC), and three of them were imported from two separate Spanish suppliers, Hamburg state health authorities said.The origin of the fourth cucumber was still under investigation, officials added.German supermarkets began to pull Spanish cucumbers off shelves Thursday afternoon following the findings in Hamburg. The food- monitoring agencies in the northern states were launching investigations on vegetable markets, the federal agriculture ministry said in a statement.Figures showed that Spain is Germany's second largest supplier of cucumbers within the European Union, accounting for some 40 percent of the country's cucumber imports.Scientists said that EHEC is a virulent strain of gut bacterium that can cause severe stomach upsets, diarrhea, stroke and coma. It would lead to kidney failure in extreme cases.Germany saw a terrible E. coli outbreak two weeks ago, starting from the northern states like Hamburg and then spreading to eastern and southern regions. German health authorities said that at least three people have died from infections, and more than 200 have been diagnosed with hemolytic-uremic syndrome (HUS), which is caused by EHEC.Germany's national disease centre, the Robert Koch Institute, suggest people avoid eating raw tomatoes, cucumbers and lettuce for a while.
