LOS ANGELES, April 11 (Xinhua) -- Drinking 100-percent fruit juice may offer disease-fighting benefits, a new study suggests.Fruit juice is linked with reduced risk of cancer, improved markers of heart health and cognitive decline, and increased antioxidant activity, according to the study published on Monday by the American Association for the Advancement of Science (AAAS).These protective health benefits are similar to those of whole fruits, said the study, conducted by researchers at the University of California, Davis.The researchers came to the conclusion after summarizing recent research data on the potential benefits of fruit juice. The review included a range of study types, from in vitro to clinical trials (60 papers total), all published in 2005 or later.Among the fruit juices included in the review, consumption of apple, citrus, cranberry, grape, and pomegranate juices all showed beneficial effects. Markers of improved health ranged from reductions in urinary tract infections (cranberry) to improvements in age-related cognitive decline (grape and apple) to reduced risk of prostate (pomegranate) and respiratory and digestive (orange, grapefruit) cancers. Additionally, intake of all juices was linked to heightened antioxidant activity."While it is universally accepted that fruit and vegetable intake is protective, there is not a clear consensus about the benefits of consuming the juices that are extracted from them," said study lead author Dianne Hyson, PhD. "An analysis of the scientific evidence suggests that 100 percent fruit juices retain important bioactive components that may promote good health and aid in disease prevention."

BEIJING, March 10 (Xinhuanet) -- The price of preventing preterm labor is about to rise drastically in the U.S. next week.A drug for high-risk pregnant women costs about 10 to 20 dollars per injection. Next week, the price will shoot up to 1,500 dollars a dose, according to media reports Wednesday.This means the total cost during a pregnancy could be as much as 30,000 dollars.The massive increase comes after KV Pharmaceutical of St. Louis won an exclusive government license to produce the drug, known as Makena.The drug, a form of progesterone given as a weekly shot, has been made cheaply for years by unlicensed chemists.The March of Dimes and many obstetricians supported the move because it means quality will be more consistent and it will be easier to get, but none of them has anticipated the sharp price hike.Doctors and campaign groups have been caught out by the move, saying that the price hike may deter low-income women from getting the drug, leading to more premature births.

LONDON, March 15 (Xinhua) -- The moon would be in a "super position" on Saturday, which makes it a "supermoon" and the web is awash with myths about its implications such as connection to recent earthquakes, but that's not the case according to British experts.Technically the so-called "supermoon" means that the moon would be in its perigee, the closest point to earth in its orbit on March 19, and on top of that, it would also be a full moon at the same time.The massive earthquake in Japan just fueled the speculation that the gravitational pull of the "supermoon" will bring chaos to the Earth, such as earthquakes and volcanic activities.But "there is little that is special about perigee on March 19," said Dr. Robert Massey, deputy executive secretary of the Royal Astronomical Society. He said the moon will be around 360,000 km from the earth on that day, but this has happened at least 15 times during the last 400 years."There is no reason whatsoever to believe that there is a connection between the so-called 'supermoon' and the recent earthquake," Massey told Xinhua. "There are also no other 'abnormal' phenomena connected with a 'supermoon' other than the high tides that we experience twice every month."Massey was echoed by Dr. Bruce Malamud, a geophysicist in the Department of Geography at King's College London, who that: "A supermoon will not be able to actually influence at all the internal workings of our Planet Earth, as there is so much momentum and mass already stored up, that the actual effect is negligible.""The earthquake took place a full 8 days before the 'supermoon' meaning that the tidal forces exerted by the moon and sun together were near their minimum rather than maximum level, directly contradicting the fearmongers," said Massey.Calling the "supermoon" claims "bogus science," he questioned the motives of those who made such claims on the day that thousands of people died in a severe earthquake and the ensuing tsunami.

BEIJING, April 19 (Xinhuanet) -- Almost one year after the disastrous oil spill, scientists believe that the overall health of the Gulf of Mexico as nearly back to normal.However, the scientists restrain their optimism about nature's resiliency with the glaring blemishes out there. It's been nearly a year since BP's Gulf of Mexico oil spill began last April, triggering one of the world's worst environmental disasters. Nearly 5 million barrels of oil leaked from the ruptured Deepwater Horizon well during the months-long catastrophe.BP said last November that the disaster cost it nearly 40 billion U.S. dollars, according to a Guardian report.According to a BP survey of researchers, over three dozen scientists grade the Gulf's big picture health a 68 on average, using a 1-to-100 scale.That's just a few points below the 71 the same researchers gave last summer when asked what grade they would give the ecosystem before the spill. And it's an improvement from the 65 given back in October after months of the oil spill.

SEOUL, April 12 (Xinhua) -- South Korea has downgraded its alert level for foot-and-mouth disease (FMD) one notch as the disease has practically come to an end, the Ministry for Food, Agriculture, Forestry and Fisheries said Tuesday.The ministry said that it lowered the alert level from "orange" to "yellow," the second-lowest status in the four-tiered alert system, as no additional burial of livestock has occurred in three weeks after the last case in Hongseong, South Chungcheong Province, on March 21.The country dropped the alert level from the highest level of " red" to "orange" on March 24.The highly contagious animal disease, first confirmed on Nov. 29, has forced the country to cull more than 3.47 million livestock, mostly pigs and cattle, resulting in losses of 3 trillion won (2.6 billion U.S. dollars).The ministry, meanwhile, said that 670 animal quarantine experts will continue to decontaminate livestock farms once every week and keep close watch to see if any animals become sick.
