VIENNA, Aug. 11 (Xinhua) -- Austrian researchers have developed a method of using fungi and produced enzymes to split Polyethylene Terephthalate (PET) material into their initial state, enabling the recovery of all individual components, said the Austrian Center of Industrial Biotechnology (ACIB) Thursday in a press release.Enzyme is a special protein that acts as biological catalyst, for example, bacteria and fungi in the nature can break down long chain molecules.Researchers from the Technical University of Graz, the Technical University of Vienna and the Agricultural University of Vienna jointly found that efficient enzymes are capable to break and split PET into small fragments.With different methods, the researchers forced the fungi to overproduce their precious "split-tools" after they are modified and improved by genetic engineering.Through the new method developed by the ACIB, it is now possible to decompose the PET polymer to its initial monomers with high product quality and from this to produce new high-quality materials again.This circuit avoids waste and thus saves resources and is friendly to the environment, said Geog Guebitz, head of the Research Department on Enzymes and Polymers in the ACIB.He further explained that the ACIB has established a partnership with some industrial enterprises to carry out application experiments. From the current splitting time of 24 hours, the researchers expect to shorten the whole process to "a few hours," he added.PET is a common plastic material in the polyester family, widely used in the textile industry. PET film is mainly used in electrical insulation materials, which can be also used for production of film, X-ray films and computer taps, even to produce plastic bottle and other blow molding products.

BERLIN, June 1 (Xinhua) -- Germany's disease control center reported on Wednesday 365 new cases of the fatal enterohemorrhagic E. coli (EHEC), which marked a sharp rise since its outbreak in the middle of May.Twenty-five percent of the new cases involved the hemolytic- uremic syndrome (HUS), a serious complication resulting from E. coli infection that affects the blood and kidneys, Germany's Robert Koch Institute said.Until now 17 people in Europe, one in Sweden, the other in Germany have been killed by the deadly disease, while the source of the infection was still not identified.According to the data of Robert Koch Institute, at present 470 patients are suffering from HUS due to the infection, raising concerns that the death toll could be even higher in the future.Germany's Agriculture and Consumer Protection Minister Ilse Aigner defended Germany's previous alert on cucumbers from Spain on Wednesday."The fatal strain of EHEC bacteria was indeed found on Spanish cucumbers. According to the European rules, a quick warning must be sent out," she told a local TV station.Laboratory tests in Hamburg on Tuesday overthrew the previous finding that Spanish cucumbers were the sources of the outbreak.As a result of the alert, Europe and Russia imposed bans on Spanish vegetables, leaving Spanish farmers a loss of 200 million euros (287.5 million U.S. dollars) a week.Spain has expressed its intention to take possible legal actions against authorities in Hamburg and ask for compensations from Germany and the European Union.

BEIJING, Aug. 3 (Xinhuanet) -- NASA Tuesday confirmed a 4-foot in diameter sphere debris as a fuel tank that was part of the space shuttle Columbia's electrical power system,according to U.S. news reports.NASA engineers identified the 4-foot piece of spherical debris as one of the18 tanks that held chilled oxygen and hydrogen used by the shuttle's electricity-generating fuel cells.This Aug. 1, 2011 handout photo provided by the Nacogdoches Police Department shows a 4-feet in diameter sphere found in Lake Nacogdoches, Texas on Monday, Aug. 1. Police say low water levels at the lake during the drought have led to recovery of a container-like object that could be from space shuttle Columbia. The shuttle broke apart and burned in February 2003, scattering remnants over East TexasPolice in the city of Nacogdoches, about 160 miles northeast of Houston, said Monday the low water levels of Lake Nacogdoches during the record drought revealed an unexpected object that could be from space shuttle Columbia. The shuttle broke apart and burned as it re-entered the atmosphere on February 1, 2003.The tank will be moved to the Kennedy Space Center, where the rest of the Columbia is stored. Approximately 40 percent of the spacecraft has been recovered.

SUVA, Sept. 21 (Xinhua) -- The Secretariat of the Pacific Community (SPC) stressed on Wednesday that sustainable use and management of forests and tree resources will remain its important focus for the foreseeable future.Sairusi Bulai, a forestry team coordinator of SPC's Land Resources Division (LRD) told a regional workshop currently underway in Fiji's western tourist city of Nadi that "our main issue was and continues to be the lack of adequate resources to enable countries to effectively implement sustainable forest management.""Therefore, we are very fortunate that we have this opportunity to discuss findings and recommendations of the mission, which the UN-REDD Program has undertaken in the Pacific earlier this year," he added.REDD+ is a new international mechanism to compensate developing countries for reducing their rate of deforestation and forest degradation and increasing their carbon stocks.Developing countries participate on a voluntary basis. They provide technical and financial assistance to enable eligible countries to meet the requirements for future participation. Once a country begins participating, it receives compensation for its verified reduction in carbon emission from forest activities.The UN-REDD Program is a collaborative partnership of the United Nations Development Program (UNDP), the United Nations Environment Program (UNEP) and the Food and Agriculture Organization (FAO) to support countries in the preparation of this mechanism.Bulai encouraged participants to take advantage of the excellent opportunity to discuss REDD+ experiences in the region and to link up with the experts in attendance.REDD+ gives an excellent opportunity to create better awareness and understanding amongst all stakeholders, including resource owners, so that informed decisions are made to avoid exploitation, he said.Bulai, meanwhile, stressed on the critical importance of multi- sectoral as well as multi-stakeholder based approaches to forest management to effectively reduce deforestation and forest degradation.

BEIJING, Aug. 23 (Xinhuanet) -- More than 90 percent of U.S. heart attack patients who need the lifesaving procedure receive it within just 90 minutes of being admitted to the hospital, according to a study released Monday in the journal Circulation.The study on the American Heart Association's journal shows that in 2010, 91 percent of heart attack patients who needed angioplasty were treated within the 90-minute window. While in 2005, 44% were.Researchers analyzed data on more than 300,000 such patients who underwent emergency angioplasty between January of 2005 and October of 2010.The improvement is the result of a nationwide effort between federal agencies, health care organizations and health care providers to improve heart attack care and outcome, said study author Dr. Harlan M. Krumholz, a professor of medicine and epidemiology and public health at Yale University School of Medicine, according to U.S. News reports.
