SHENYANG, Feb.3, (Xinhua) -- Fire gutted Thursday a five-star hotel in Shenyang, capital of northeast China's Liaoning Province, and no casualties had been found, local officials said.The fire broke out at 0:13 a.m. at Tower B, an apartment building of the Dynasty Wanxin building complex, and the flames quickly spread to the adjacent Tower A, which is largely a five-star hotel.All the 50-odd people in the hotel were evacuated. No casualties are found.The fire was effectively controlled, Shenyang Municipal Public Security Bureau officials told Xinhua at 4:35 a.m..Police said the fire was triggered by fireworks, which accidentally sparked off the external wall of the buildings. Further investigation into the cause and losses of the fire is still underway.Fire engines, whose water guns could jet water only 50 meters high, were helpless at the fire which flamed on the top of Tower A, 219 meters high.Power supply in the hotel was not cut off, which was said to keep the automatic spray facilities in operation in the building.Personnel from adjacent five-star Sheraton Shenyang Lido Hotel were evacuated, and residents around the Dynasty Wanxin building mainly stayed at home.Top leaders of the province and the city, including Chen Haibo, mayor of Shenyang, arrived at the site soon afterwards to direct efforts to quell the fire.The Dynasty Wanxin building complex, located in the bustling Qingnian Street of Heping District, comprises of three towers. The fire engulfed Tower A and B, with Tower C intact.

LOS ANGELES, April 4 (Xinhua) -- A woman's breast milk cells may be used to predict cancer in future research, according to a study published by HealthDay News on Monday.In the study, researchers at the University of Massachusetts in Amherst collected breast milk from 271 women in the United States. All had either undergone a biopsy of the breast to check for cancer, or were scheduled for one.The researchers evaluated breast milk samples from the biopsied and non-biopsied breasts.The researchers first isolated potentially cancerous cells, known as epithelial cells, and then isolated DNA to look for signals that regulate tumor suppresser genes.In the next step, the researchers analyzed three genes among the many known to undergo a process called methylation in breast cancer. Methylation in a specific region of a gene can inhibit or suppress the expression of a gene.For one gene, SFRP1, the average methylation was higher in the biopsied breast, the study found.Among the women whose biopsies detected cancer, average methylation of the RASSF1 gene in the biopsied breast was considerably higher compared to the non-biopsied breast.Among the women whose biopsies detected cancer, average methylation of the RASSF1 gene in the biopsied breast was considerably higher compared to the non-biopsied breast."It looks as if we can use the cells from breast milk to assess breast cancer risk," said Dr. Kathleen Arcaro, an associate professor of veterinary and animal sciences at the university.It's too soon, however, to assess the cancer detection rate associated with breast milk cell examination, she said."We can't say at this point for two reasons," she said. "One is, we need long-term follow-up. And the second really important reason is, we need to sample a larger panel of genes."Arcaro is to present her findings later Monday at the annual meeting of the American Association for Cancer Research in Orlando, Florida, according to HealthDay News.

BEIJING, Feb. 5 (Xinhua) -- China's railways transported about 77.34 million passengers during the fifteen days (Jan. 19 to Feb. 2) before the Spring Festival, the Ministry of Railways said.The figure was about 9.5 percent higher than the same period last year and set a new record, according to a report posted on the ministry's website.There were an average of 5.16 million passengers per day, up 448,000 from the same period last year. On Jan. 29, passengers topped 5.78 million, setting a new record for daily transportation before the Spring Festival, the report said.In the fifteen days before the festival, about 4.80 million passengers left Beijing, 8.39 million left Guangzhou and 5.69 million left Shanghai, while year-on-year growth and those leaving Guangzhou rose the most, up 15 percent year on year, said the report.The ministry said challenges still exist as more snow and rain will hit southern China after the Spring Festival, when passengers are returning.China's busy Spring Festival transportation season runs for 40 days and is calculated in two phases: 15 days before the Spring Festival and 25 days after the Spring Festival, the report explained.

LOS ANGELES, April 18 (Xinhua) -- Sugarcane has the effect of cooling temperatures, thus playing role in stemming global warming, a new study has found.Sugarcane does so by reflecting sunlight back into space and by lowering the temperature of the surrounding air as the plants " exhale" cooler water, according to the study conducted by researchers at the Carnegie Institution's Department of Global Ecology.The researchers used data from hundreds of satellite images over 733,000 square miles (about 1,173 square kilometers) in Brazil, where sugarcane is widely grown. They measured temperature, reflectivity (also called albedo), and evapotranspiration -- the water loss from the soil and from plants as they exhale water vapor.The findings showed that expansion of sugarcane in areas previously occupied by other Brazilian crops cools the local climate.Converting from natural vegetation to crop/pasture on average warmed the cerrado by 2.79 Fahrenheit (1.55 Centigrade, but that subsequent conversion to sugarcane, on average, cooled the surrounding air by 1.67 Fahrenheit (0.93 Centigrade), the researchers said in the study published in the April issue of Nature Climate Change."We found that shifting from natural vegetation to crops or pasture results in local warming because the plants give off less beneficial water. But the bamboo-like sugarcane is more reflective and gives off more water -- much like the natural vegetation," said lead researcher Scott Loarie. "It's a potential win-win for the climate -- using sugarcane to power vehicles reduces carbon emissions, while growing it lowers the local air temperature."Brazilians are world leaders in using biofuels for gasoline. About a quarter of their automobile fuel consumption comes from sugarcane, which significantly reduces carbon dioxide emissions that otherwise would be emitted from using gasoline.The researchers emphasized that the beneficial effects are contingent on the fact sugarcane is grown on areas previously occupied by crops or pastureland, and not in areas converted from natural vegetation. It is also important that other crops and pastureland do not move to natural vegetation areas, which would contribute to deforestation.So far most of the thinking about ecosystem effects on climate considers only impacts from greenhouse gas emissions. But according to co-researcher Greg Asner, "It's becoming increasingly clear that direct climate effects on local climate from land-use decisions constitute significant impacts that need to be considered core elements of human-caused climate change."

BEIJING, Feb. 6 (Xinhua) -- Chinese Vice Premier Hui Liangyu on Sunday urged local authorities to intensify efforts to prevent forest fires.The senior Chinese official also ordered the country's forest fire prevention departments to come up with emergency response measures to be implemented as soon as fires break out.Hui warned that the country faced severe challenges from forest fires as the drought in the north continued and there was less rain than normal in the south in February.A total of 168 forest fires were recorded from Feb. 2 to Feb. 6, according to monitoring stations from the country's forest fire management authority.On Saturday, a forest blaze killed six people and left another three injured in east China's Zhejiang Province. Local officials said fireworks were the likely cause of the tragedy.
