MOSCOW, Aug. 6 (Xinhua) -- The Arctic is getting warmer at a fast pace with the Russian Arctic sector's ice areas contracting to historically low levels, according to Russian meteorological bureau Rosgidromet.According to a Rosgidromet report cited by Itar-Tass news agency Saturday, the polar cap in the Russian sector has shrunk to the historical low registered in 2007, with no ice expected to block the Northern Seaway at least until September."Currently, Arctic navigation conditions are very favorable. By early August, navigation can be done without icebreakers almost along the entire route," said Valery Martyshchenko, head of Rosgidromet's environment pollution monitoring department.According to the Arctic and Antarctic Research Institute, the current ice cover in the Arctic Ocean is 6,860 million square kilometers, way below average.Martyshchenko said the longer period of icebreaker-free navigation would benefit the regions located in the Arctic area, allowing longer access to food and energy supplies, but the warming of the climate also posed new threats, such as melting of ice and forming of icebergs.

WASHINGTON, June 21 (Xinhua) -- A new study from Harvard School of Public Health (HSPH) and University of California, San Francisco, researchers suggests that men with prostate cancer who smoke increase their risk of prostate cancer recurrence and of dying from the disease. The study will be published Wednesday in the Journal of the American Medical Association."In our study, we found similar results for both prostate cancer recurrence and prostate cancer mortality," said Stacey Kenfield, lead author and a research associate in the HSPH Department of Epidemiology. "These data taken together provide further support that smoking may increase risk of prostate cancer progression."Kenfield and her colleagues conducted a prospective observational study of 5,366 men diagnosed with prostate cancer between 1986 and 2006 in the Health Professionals Follow-Up Study. The researchers documented 1,630 deaths, 524 (32 percent) due to prostate cancer, 416 (26 percent) due to cardiovascular disease, and 878 prostate cancer recurrences.The researchers found that men with prostate cancer who were current smokers had a 61 percent increased risk of dying from prostate cancer, and a 61 percent higher risk of recurrence compared with men who never smoked. Smoking was associated with a more aggressive disease at diagnosis, defined as a higher clinical stage or Gleason grade (a measure of prostate cancer severity). However, among men with non-metastatic disease at diagnosis, current smokers had an 80 percent increased risk of dying from prostate cancer.Compared with current smokers, men with prostate cancer who had quit smoking for 10 or more years, or who had quit for less than 10 years but smoked less than 20 pack-years before diagnosis, had prostate cancer mortality risk similar to men who had never smoked. Men who had quit smoking for less than 10 years and had smoked 20 or more pack-years had risks similar to current smokers."These data are exciting because there are few known ways for a man to reduce his risk of dying from prostate cancer," said senior author Edward Giovannucci, professor of nutrition and epidemiology at HSPH. "For smokers, quitting can impact their risk of dying from prostate cancer. This is another reason to not smoke."Prostate cancer is the most frequently diagnosed form of cancer diagnosed in the United States and the second leading cause of cancer death among U.S. men, affecting one in six men during their lifetime. More than two million men in the U.S. and 16 million men worldwide are prostate cancer survivors.

BEIJING, Aug. 12 (Xinhuanet) -- A Connecticut woman who was savagely attacked by a pet chimpanzee and had her face deformed in 2009 was shown on TV with a new face Thursday.TV pictures revealed Charla Nash’s new nose, lips and eyelid, which were transplanted in May by doctors at the Brigham and Women’s Hospital in Boston.Nash said to the viewers that she can move her mouth, smile and smell. Her daughter Brianna added that her mother can even talk and eat better now.Dr. Bohdan Pomanhac led a 30-member surgical team to complete the face transplant in 20 hours. The team also transplanted two hands but these were later removed due to blood flow problem when Nash suffered pneumonia.Nash’s friend Sandra Herold owned a 15-year-old chimpanzee named Travis that attacked without any provocation when Nash was visiting Herold.Travis simply went berserk and could not be stopped even after Herold stabbed it with a kitchen knife. It would only let go of Nash after the police arrived and shot it dead.

WASHINGTON, Aug. 24 (Xinhua) -- Online search engine Google Inc. has agreed to pay 500 million U.S. dollars to settle claims that it allowed online Canadian pharmacies to place advertisements targeting consumers in the United States, U.S. Justice Department announced Wednesday.The settlement, one of the largest ever in the United States, represents the gross revenue received by Google as a result of Canadian pharmacies advertising through Google's AdWords program, plus gross revenue made by Canadian pharmacies from their sales to U.S. consumers.The advertisements led to illegal imports of prescription drugs into the country, the Justice Department said.The shipment of prescription drugs from pharmacies outside the United States to customers in the United States typically violates the Federal Food, Drug and Cosmetic Act and in the case of controlled prescription drugs, the Controlled Substances Act.Google was aware as early as 2003, that generally, it was illegal for pharmacies to ship controlled and non-controlled prescription drugs into the United States from Canada."The Department of Justice will continue to hold accountable companies who in their bid for profits violate federal law and put at risk the health and safety of American consumers," Deputy Attorney General James Cole said in a statement."This settlement ensures that Google will reform its improper advertising practices with regard to these pharmacies while paying one of the largest financial forfeiture penalties in history," he said.Google had previously set aside that amount for a possible settlement over its advertising practices, according to a regulatory filing in May.

SAN FRANCISCO, July 29 (Xinhua) -- Apple has ousted Nokia as the world's largest smartphone maker as global mobile phone market grew more than 11.3 percent in the second quarter of 2011, according to two separate market research studies.After becoming the largest smartphone vendor in terms of revenue and profits, Apple has become the world's largest smartphone vendor by volume with 18.5 percent market share, said the latest research from Strategy Analytics released on Friday.The Cupertino, California-based company sold 20.3 million iPhones in the second quarter,up 142 percent compared with the same period a year earlier.Samsung's shipments of 19.2 million units grew a huge 520 percent year over year, accounting for 17.5 percent global smartphone market share in the second quarter of 2011.Apple and Samsung overtook long-time volume leader Nokia for the two spots. The Finnish mobile phone giant accounted for 15.2 percent of global smartphone market share in the last quarter, which is less than half of what it was just one year earlier.In the second quarter of 2010, Nokia was the No.1 smartphone maker by volume in the world with 38.1 percent of market share. The industry is now waiting Nokia's pending transition to Windows Phone 7.According to a separate report by International Data Corporation (IDC) released on Thursday, the worldwide mobile phone market grew by 11.3 percent year over year in the second quarter of 2011 despite a decline of the feature phone market for the first time in almost two years.The feature phone market was down by 4 percent in the last quarter, said the IDC Worldwide Mobile Phone Tracker report. It noted that the decline in shipments was mainly in economically mature regions, such as the United States, Japan and Western Europe, as users making rapid transition to smartphones.The shrinking feature phone market had a great impact on some of the world's largest suppliers of mobile phones, such as Nokia, which is losing share in the feature phone category to low-cost suppliers, said the report.For the overall market, global mobile phone vendors shipped 365. 4 million units in the second quarter, compared to 328.4 million units in the same period last year, with Nokia still holding the top spot with a market share of 24.2 percent, followed by Samsung, LG Electronics, Apple and ZTE.But the 11.3 percent growth was lower than IDC's forecast for the quarter and also below the 16.8 percent growth in the first quarter of 2011.IDC said the feature phone forecast isn't expected to be any rosier in the future and the shipment growth of feature phones won 't exceed 1.1 percent in the coming years.
