BEIJING, Aug. 12 (Xinhuanet) -- Engineers at the University of Illinois have unveiled novel, skin-mounted electronics whose circuitry bends, wrinkles, and even stretches with skin, according to media reports quoting the Science Friday.The device platform includes electronic components, medical diagnostics, communications, and human-machine interfacing on a patch so thin and durable that it can be mounted to skin much like a temporary tattoo, the jounral described.What's more, the engineers demonstrated the invention across a wider range of components, including LEDs, transistors, wireless antennas, sensors, and conductive coils and solar cells for power."We threw everything in our bag of tricks onto that platform, and then added a few other new ideas on top of those to show that we could make it work," said engineering professor John A. Rogers in a news release.

WASHINGTON, Sept. 13 (Xinhua) -- The U.S. Department of Agriculture (USDA) announced Tuesday it will begin testing next year for six more kinds of E.coli bacteria in raw ground beef and tenderized steaks in order to protect the safety of the American food supply.The U.S. currently tests for one strain of E.coli O157:H7 in beef. According to the USDA, from March 5 next year, if the E. coli serogroups O26, O103, O45, O111, O121 and O145 are found in raw ground beef or its precursors, those products will be prohibited from entering commerce.Like E.coli O157:H7, these serogroups can cause severe illness and even death, and young children and the elderly are at highest risk."The Obama Administration is committed to protecting our food supply and preventing illnesses before they happen," said Agriculture Secretary Tom Vilsack in a statement. "Today's announcement does exactly that by targeting and eliminating contaminated products from the market.""Too often, we are caught reacting to a problem instead of preventing it. This new policy will help stop problems before they start," he said.About one in six Americans becomes sick from a food borne illnesses each year, an epidemic that kills about 3,000 annually and hospitalizes 128,000, according to the U.S. Centers for Disease Control and Prevention.

WASHINGTON, Aug. 11 (Xinhua) -- The unique fossils of an adult plesiosaur and its unborn baby may provide the first evidence that these ancient animals gave live birth like mammals, according to a new study to be published Friday in the journal Science.The 78-million-year-old, 15.4-foot-long (4.7-meter-long) adult specimen is a Polycotylus latippinus, one of the giant, carnivorous, four-flippered reptiles that lived during the Mesozoic Era.Dr. Robin O'Keefe of Marshall University in West Virginia and Dr. Luis Chiappe, Dinosaur Institute director of the Natural History Museum in Los Angeles County, have determined that it is the fossil of an embryonic marine reptile contained within the fossil of its mother.The embryonic skeleton contained within shows much of the developing body, including ribs, 20 vertebrae, shoulders, hips, and paddle bones.O'Keefe and Chiappe have also determined that plesiosaurs were unique among aquatic reptiles in giving birth to a single, large offspring, and that they may have lived in social groups and engaged in parental care.Although live birth has been documented in several other groups of Mesozoic aquatic reptiles, no previous evidence of it has been found in the important order of plesiosaurs."Scientists have long known that the bodies of plesiosaurs were not well suited to climbing onto land and laying eggs in a nest," O'Keefe said."So the lack of evidence of live birth in plesiosaurs has been puzzling. This fossil documents live birth in plesiosaurs for the first time, and so finally resolves this mystery."

BEIJING, Sept. 27 (Xinhuanet) -- Scientists have been making great efforts to show how harmful coffee is to us, though no evidence yet. A latest study may be reassuring for coffee-lovers.Women who drink caffeinated coffee are less likely to be depressed than those don't. And the more they drink, the lower risk of developing depression, according to a study published Monday in the Archives of Internal Medicine. Researchers of the study tracked the health of over 50,000 women aged between 30 and 55 in 1996 for a decade and recorded their mental health and coffee intake periodically.They find that women who drank two or three cups of coffee per day were 15 percent less likely than those who drank little or decaffeinated coffee to be depressed.And for those who drank four or more cups, the risk of developing depression reduced by 20 percent.The reason why coffee could protect depression is not clear. But the scientists from the Harvard University speculated that caffeine was the key player. More research is needed to show whether caffeine can ward off depression.It might be that not-depressed people tended to be more activated and the habit of coffee drinking just fit in their lifestyle.However, the depressed ones, who might suffer from sleeplessness, chose not to drink coffee because the caffeine might exacerbate it."There's no need to start drinking coffee," said Dr. Alberto Ascherio, the senior author of the study, "The message is that coffee is safe to drink, with no adverse effects. That's really all that can be said."

BEIJING, July 11 (Xinhuanet) -- The pace of China's import growth in June fell to its lowest level in 20 months as tightening monetary policies kicked in, resulting in the biggest monthly trade surplus this year, official statistics show.Import growth is expected to slow in the coming months, thanks to the broad impact of the tightening measures, before picking up in the last quarter, economists predicted.According to the General Administration of Customs (GAC), imports rose 19.3 percent, from a year earlier, to 9.7 billion, the weakest since November 2009.Exports rose 17.9 percent and despite this being the smallest increase since last December they reached a record high of 1.9 billion.The decline in import growth has led to a widening trade surplus, .3 billion in June compared to .1 billion in May. But in the first six months the trade surplus dropped 18 percent, year-on-year, to .9 billion."Import growth was weaker than expected, as imports for China's processing trade weakened and de-stocking in heavy industry continued," Wang Tao, head of China Economic Research at UBS Securities, said."Recent commodity price drops, including crude oil, also helped lower the import bill," she added.June's net imports of crude oil fell 12 percent from May to 19.43 million metric tons, the lowest since October, amid refinery maintenance and slowing energy demand, according to the GAC figures."Decelerating economic growth and tightening measures to soak up market liquidity have reined in import growth, but it is not a cause for worry," Li Wei, an economist at Standard Chartered Shanghai, said.The government is expected to announce economic growth data for the second quarter on Wednesday. Gross domestic product growth is widely predicted to slow from 9.7 percent for the first quarter."The slowdown in import growth will last two to three months or even longer due to both falling demand and possible commodity price drops," Li said.Zhong Shan, vice-minister of commerce, said recently that imports will slow down in the second half, citing the government's measures to cool the economy.The central bank has raised interest rates five times since mid-October, with the latest on July 7, and increased the reserve requirements for commercial banks, the amount they have to set aside, nine times since November. The consumer price index, a major gauge of inflation, surged to 6.4 percent last month, the highest in three years.Zhao Fudi, GAC spokesman, said in an online broadcast on Sunday that higher prices are increasing inflationary pressure, leading to a 14.7 percent gain in the overall price of imported commodities in the first half.Imports surged 27.6 percent year-on-year to 9.4 billion from January to June, as commodity prices rose during the first half. Exports increased 17.9 percent in June, down from 19.4 percent in May."This is because of weaker external demand" from developed nations, Wang said.Exports increased 24 percent, year-on-year, to 4.3 billion during the first half, but exports to both the United States and the European Union, China's two major trading partners, rose by only 16.9 percent."The slow recovery of the global economy and the European debt crisis have added uncertainties to export growth," Zheng Yuesheng, head of the GAC statistics department, said.Lu Zhengwei, chief economist at Industrial Bank, believes that the March earthquake and tsunami in Japan hurt China's exports."The disaster cut off China's imports of parts and components used for mechanical and electrical goods, leading to a decline in those exports" which make up a majority of China's exports, Lu said.As Japanese manufacturers resume full production, or come close to it, in September, China's exports will regain momentum, he predicted.Li Wei agreed. "China's exports keep pace with the global economic recovery. And growth will probably see a turnaround in September" when orders for the Christmas season are usually made, Li said.Many companies in China's coastal regions are far from optimistic, citing rising costs in labor and raw materials and yuan appreciation, as well as shrinking demand abroad.Han Jie, deputy director general of the department of commerce in Zhejiang province, said "exporters in Zhejiang have experienced a disappointing first half, and the second half will not be better".
