LOS ANGELES, April 29 (Xinhua) -- Clinical and teaching microbiology laboratories are linked with a nationwide salmonella outbreak in the United States that has killed one person and sickened dozens of others, health officials confirmed on Friday.Since August, about 73 people in 35 states have been sickened by salmonella bacteria, and some of those cases involve a strain of Salmonella typhimurium sold commercially to laboratories, officials from the Centers for Disease Control and Prevention (CDC) said in remarks published by msnbc.com.Illnesses have been tied to laboratories from Alaska to New York, with most reporting one or two cases. Five cases have been reported in Washington state and four in Minnesota.The first illness occurred late August and the most recent cases were reported March 8, according to the CDC.The patients include employees and students of the laboratories, as well as children in the homes of people who work or study at the labs.Patients ranged in age from less than one to 91, with a median age of 24, the CDC said.Cases that developed after March 19 may not yet be included in the total because of the lag time in assessing and reporting illness, said the report.CDC officials warned that bacteria used in the labs can be transmitted through contaminated lab coats, pens, notebooks, car keys and other items brought into the labs.The CDC is working with local and state health departments, the American Society for Microbiology and the Association of Public Health Laboratories to track the outbreak, the report said.Salmonella infections typically result in diarrhea, fever and abdominal cramps. They can be dangerous in very young children or people with compromised immune systems.

CANBERRA, April 14 (Xinhua) -- Scientists on Thursday expressed disappointment to the decision to cancel the long-running Australian Science Festival in Canberra.The festival has been operating during August for the past 19 years with free and ticketed science education activities.However, the festival organizers on Wednesday announced to halt this year's program after failing to secure support from the Australian Capital Territory state government in time to arrange events.According to Australian Science Communicators president, Jesse Shore, thousands of school children have attended the festival over its history to learn more about science as a career."It's encouraged other activities to join it, it was very important in getting National Science Week started, and that's stimulated a lot of other science communication activities," he told ABC News on Thursday.Shore said the decision to close it down is unfortunate as the event has been very influential and instrumental promoting science communications activities.He said he hopes that a number of people would gather together in a new partnership, with new ideas and hopefully a new funding base.

BEIJING, Feb. 10 (Xinhua) -- First snow fell in Beijing Wednesday night and continued into Thursday morning. It was the latest first snow for the city in 60 years.Beijing has had no precipitation for 108 consecutive days this winter.Local meteorologists said from 8:00 Wednesday to 6:00 Thursday, precipitation in Beijing averaged 1 mm."Now there is snow at last. I love the taste of snow." "The world in pure white! It's the most beautiful landscape in winter." Beijing residents who stayed late in the night and happened to see the first flakes of snow in the city left their postings on microblogs.However, meteorologists said the first snow won't last long and it will end on Thursday noon. In midnight, the city will have a cloudy weather, and Friday will be a sunny day."As the precipitation is small, it will have limited effect on easing drought," Song Jisong, the municipal meteorological bureau's chief weather forecaster said.Sun said that the capital city's record-long winter drought occurred in the winter of 1970/71, when there was no precipitation for 114 days. This winter drought was the second longest in 60 years.Meteorologists said the current snowfall will reduce risks of fire.The snow also affected the city's traffic. Local traffic control authorities estimated that there were more than 40 highways on which vehicles ran at a speed lower than 20 km per hour in the rush hour Thursday morning.The authorities said an emergency headquarters had been set up for the snow weather. Expressways connecting Beijing with Chengde, Tianjin and Tibet will likely have some sections closed for the time being.A spokesperson with the Beijing Capital International Airport Co., Ltd. said that by 6:00 a.m. Thursday, runways at the airport had operated normally, and take-offs and landings had been normal, with no flights delayed.The airport has also launched an emergency scheme. At last 64 ice removal vehicles had been arranged to ensure the normal operaton of flights.Wednesday also saw snowfall and sleet in Gansu, Shaanxi, Shanxi, Henan and Anhui provinces and rainfall in the Yellow River and Huaihe River valleys, southwestern regions and the middle-and-lower reaches of the Yangtze River valley. And snow and rainfall will continue in the those areas Thursday.

COPENHAGEN, April 30 (Xinhua) -- As traditional Chinese medicine (known as TCM in Europe) becomes increasingly popular worldwide and has gradually been regarded as a useful component to Western medical treatments, Denmark is no stranger to such trends.According to a study published by the University of Copenhagen in mid-Feb., up to one-third of Danish hospitals choose complementary or alternative therapies, including TCM methods, to treat pain, cancer, mental disease, tumors and infertility. Acupuncture remains the most widely-practiced form of these treatments, used in some 97 percent of the cases.The nationwide acceptance of acupuncture and massage therapists, the growing ranks of herbal practitioners, and the hosting of an annual pan-Scandinavian TCM conference since 2007, all underline the popularity of alternative medicine, including the TCM, in the country.However, the overall market presence of TCM, and herbal medicines in particular, is relatively small in Denmark and Europe at large. As many European policymakers insist that traditional herbal medicines "are neither scientifically documented nor tested according to Western requirements," these treatments face difficulties in obtaining licenses and boosting sales in Europe.In fact, despite their historical pedigree and widely-accepted efficacy, TCM products are often classified as "healthcare products" or "food," rather than "drugs" in European markets.A big challenge for TCM products to gain more access to the continent is the EU's Traditional Herbal Medicinal Products Directive, which stipulates that all such products must obtain authorization if they are to be sold within the EU, starting May 1, 2011.The directive says producers must prove the product in question has been used for 30 years, 15 of which within the EU, so as to ensure its safety.While licensing is expected to be onerous and expensive, Denmark has tried to bring TCM products into the Western medical mainstream from as early as 2005. The country's well-developed biochemical and medical industry, modernized agriculture and horticulture sectors and a strong track record of cooperative research in these fields, has helped TCM's cause.For instance, Traditional Complementary Medicine Denmark, a company helping herbal product makers market their goods in Western countries, uses modern biotechnology processes and clinical trials to scientifically verify and document the efficacy of existing herbal medicines.It also advises herbal product makers on how to align their standards with European requirements so as to acquire the necessary sales licenses. Sometimes, simple solutions like clearer and more detailed labeling of a TCM product's ingredients can help improve its marketability. Patent applications and drug approvals procedures must follow, before the product can access the EU pharmaceutical market, usually in pill form.Investing in herbal medicine also makes financial sense for Denmark, as it is encourages development of low-bulk, high-value agricultural products, which can be easily transported all over the globe.Development Centre Aarslev, a Danish agro-research body and partner of TCM Denmark, studies the active ingredients contained in medicinal plants and their impact on human health conditions such as cardiovascular problems, diabetes and allergies. One of the earliest collaborations it undertook with a producer of herbal medicine showed the effectiveness of extracts from the hips of the dog rose plant in treating rheumatoid arthritis.A spokesperson for the institution said, "We have documented analytical evidence which shows that arthritis patients can reduce their consumption of conventional anti-arthritis drugs by up to 50 percent, if they combine them with the herbal drug based on dog rose hips."Given Denmark's population of 5.5 million people, this could translate into savings of 200 million U.S. dollars a year on anti-arthritis medication, the spokesperson added.Other plant-based interventions could hold wider public health benefits. TCM practitioners say herbal medicines can improve blood circulation in humans, and contain naturally-occurring antioxidants which can reduce the risks of heart attacks and better regulate cardiovascular functions. This has potentially wide-ranging benefit for Western societies, where heart disease is a major threat.Heart disease was the most common cause of death in Denmark until 2000, and cardiovascular disease the commonest until 2008, with cancer now ranking the biggest killer.In fact, TCM herbal remedies are also considered a good choice for cancer treatment, as certain plants contain hormone-like substance which can influence hormone-dependent cancers, such as breast and prostate cancer.TCM supporters say the obvious benefit of such an intervention is the avoidance of more commonly-used chemotherapy and radiation treatments which often produce severe side-effects in patients. Relevant herbal therapies can help strengthen cancer patient's immune system, reduce side-effects of chemotherapy and radiation therapy, and alleviate other symptoms of the disease.Given the many potential benefits of TCM, the EU's tightening of rules may appear harsh. Still, TCM is considered a relatively novel approach to medicine in Europe. Moreover, the dominant market share and general clout of the chemical-based, Western pharmaceutical industry also makes it difficult for traditional remedies to stake their claim.
