BEIJING, Nov. 4 (Xinhuanet) -- The amount of trans fat and other nutritional information will be marked on the labels of prepackaged food, according to the country's first national standard for food nutrition. The labeling will take effect on Jan 1, 2013. "It will help standardize the nutrition facts labeling by food producers and facilitate consumers' rights to know and choose, while improving public awareness of food nutrition," said Yang Yuexin, a senior nutritionist with the Chinese Center for Disease Control and Prevention (CDC). The new regulation by the Ministry of Health stipulates that food labels have to include the food's nutrition information, including levels of energy, protein, fat, carbohydrate and sodium. Food products without proper labels showing the nutritional information will be banned when the new rule takes effect. The new regulation also stipulates that if any hydrogenated or partially hydrogenated fat is used to produce the food, the level of trans fat will have to be highlighted on the nutrition information label. Trans fat is usually produced during food processing when liquid oils are converted into semi-solid fats that help keep food fresh longer. However, the partially hydrogenated oil contains trans fat that can substantially increase the risk of heart disease. However, Zhang Jian, a researcher with CDC's National Institute for Nutrition and Food Safety, said that compared to Western diets, the Chinese diet contains a far lower level of trans fat and there is no need to over react.

WASHINGTON, Nov. 21 (Xinhua) -- The use of acupuncture for children is common and acupuncture is generally safe for children when performed by "appropriately trained practitioners," Canadian researchers reported Monday in online journal Pediatrics.Researchers at the University of Alberta looked at data from 37 studies of needle acupuncture, spanning 60 years, on children from birth to age 17, and assessed the association between needle acupuncture and various levels of adverse events in children. They found that of 279 adverse events identified, 253 were mild, one was moderate and 25 were serious.Serious side effects included bleeding, infections, and heart and lung problems. One child may have contracted HIV. But the researchers said the serious side effects were related to substandard conditions from the care provider, rather than acupuncture's technique itself. They concluded that in trained hands, pediatric acupuncture is safe.Acupuncture has been around for thousands of years, and traditional Chinese theory suggests needle placement helps balance the body's energy flow, called "qi". Acupuncture is sometimes used to treat headaches, migraines, back and joint pains, cramps, and chemotherapy-induced nausea. Estimates show 150,000 U.S. children undergo acupuncture each year.

BEIJING, Oct. 24 (Xinhuanet) -- The average global land temperature has increased by around one degree Cetigrade since the mid-1950s, American scientists announced last week after reviewing historical temperature records to date.According to media reports, the scientists of the Berkeley Earth project have studied more than a billion temperature records dating back to the 1800s from 15 sources around the world.And the result is in line with the estimate made by major institutions which keep official records on the global climate, including the Nasa's Goddard Institute for Space Studies in the US and the Met Office's Hadley Centre in Britain.Meanwhile, the scientists established an open database for the climate records so that skeptics on climate change can assess climage change on their own.Nevertheless, the finding of the scientists at the University of California, Berkeley did not convince climate change skeptics, according to a New York Times report.Anthony Watts, one prominent US skeptics, claimed the study's "methodology was flawed". He also noted that the finding was submitted to journal Geophysical Research Letters before being peer-reviewed.Richard Muller, a physicist and head of the project, argued that the decision to circulate the papers before publication was part a long-standing academic tradition of sanity-checking results with colleagues.He added, cited by the Guardian, "We will get much more feedback from making these papers public before publication."

WASHINGTON, Dec. 20 (Xinhua) -- NASA's Kepler mission has discovered the first Earth-size planets orbiting a sun-like star outside our solar system, the U.S. space agency announce Tuesday.The planets, called Kepler-20e and Kepler-20f, are too close to their star to be in the so-called habitable zone where liquid water could exist on a planet's surface, but they are the smallest exoplanets ever confirmed around a star like our sun, according to NASA.The discovery marks the next important milestone in the ultimate search for planets like Earth. The new planets are thought to be rocky. Kepler-20e is slightly smaller than Venus, measuring 0.87 times the radius of Earth. Kepler-20f is slightly larger than Earth, measuring 1.03 times its radius. Both planets reside in a five-planet system called Kepler-20, approximately 1, 000 light-years away in the constellation Lyra.Kepler-20e orbits its parent star every 6.1 days and Kepler-20f every 19.6 days. These short orbital periods mean very hot, inhospitable worlds. Kepler-20f, at 800 degrees Fahrenheit, is similar to an average day on the planet Mercury. The surface temperature of Kepler-20e, at more than 1,400 degrees Fahrenheit, would melt glass."The primary goal of the Kepler mission is to find Earth-sized planets in the habitable zone," said Francois Fressin of the Harvard-Smithsonian Center for Astrophysics, lead author of a new study published in the journal Nature. "This discovery demonstrates for the first time that Earth-size planets exist around other stars, and that we are able to detect them."The Kepler-20 system includes three other planets that are larger than Earth but smaller than Neptune. Kepler-20b, the closest planet, Kepler-20c, the third planet, and Kepler-20d, the fifth planet, orbit their star every 3.7, 10.9 and 77.6 days. All five planets have orbits lying roughly within Mercury's orbit in our solar system. The host star belongs to the same G-type class as our sun, although it is slightly smaller and cooler.

BEIJING, Oct. 18 (Xinhuanet) -- Some seaweeds can kill the reef-building corals around them by emitting anti-coral chemicals, a new study found.The study was published Monday in the online edition of the journal Proceedings of the U.S. National Academy of Sciences (PNAS).The researchers investigated the interactions between eight different species of seaweed and three species of coral growing in the waters nearby the Fiji Islands, and identified a class of anti-coral organic compounds known as terpenes.These chemicals, found on the surfaces of several species of seaweed, can kill the coral by suppressing its photosynthesis.The finding suggests that the living space competition with seaweeds could be a factor of the coral's worldwide decline.Plant-eating fish normally controls seaweed growth on coral reefs, but the populations of these consumers are declining by the overfishing, which eventually resulted in the seaweed's dominant position, according to the researchers.Despite overfishing, pollution and warming oceans are also the contributors to coral's worldwide decline, said Jennifer Smith, a marine ecologist at the University of California, San Diego.
