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.

SAN FRANCISCO, Sept. 13 (Xinhua) -- Researchers in San Francisco, U.S. have found in a latest study that bisphenol A (BPA) and methylparaben, two chemicals commonly used in consumer products, can interfere with the breast cancer drugs, local media reported on Tuesday.In the study, doctors from California Pacific Medical Center in San Francisco found that healthy breast cells from high-risk patients started to find ways to bypass breast cancer drugs after they were exposed to BPA and methylparaben in the lab.The cells exposed to the two chemicals kept growing and didn't die after they were introduced with Tamoxifen, a current standard drug therapy for female breast cancer and most common used treatment for male breast cancer, Dr. William Goodson, lead author of the study, told San Francisco Chronicle.Goodson said that BPA and methylparaben not only mimic estrogen 's ability to drive cancer, but appear to be even better than the natural hormone in bypassing the ability of drugs to treat it. The finds have been published online in the British medical journal Carcinogenesis.The research shows more evidence of safety issues of BPA, a chemical primarily used to make plastic baby bottles, food containers, household electronics and etc, as well as the less known methylparaben, a chemical preservative used in cosmetics and other personal care products.The researchers noted that the breast cancer rates have been growing by about the same amount in men as in women over the past three decades. Scientists have been looking at environmental causes for the disease and wondering where the hormones are coming from.Goodson said BPA and methylparaben are used so widely and even found in household dust, noting that it is still unknown whether the effects of exposure to the chemicals are reversible.Since 2008, several governments issued reports questioning the negative health effects of BPA, especially raising concerns regarding exposure of fetuses, infants and children. BPA use has been banned in baby bottles in a lot of countries and regions.As for methylparaben, the U.S. Food and Drug Administration said on its website that "at the present time there is no reason for consumers to be concerned about the uses of cosmetics containing parabens (including methylparaben)."

MOSCOW, Aug. 26 (Xinhua) -- Russia will carry out two unmanned test launches of Soyuz carrier rockets in the coming fall before delivering crews to the International Space Station (ISS), local media reported on Friday.Citing a source, RIA Novosti news agency said that one of the Soyuz rockets was scheduled to send a new Progress M-13M space freighter to the ISS.On Wednesday, a Progress M-12M cargo ship failed to reach the orbit after the engine of a Soyuz-U carrier rocket turned off during the ascend. Soon after the accident, Russia announced it will temporarily ground all Soyuz rockets.Due to the accident, Russian space authorities have put off Thursday's launch of a Soyuz-2 carrier rocket from the Plesetsk Space Center in northern Russia and a launch of a manned space ship from Baikonur space center in Kazakhstan.After the retirement of the U.S. shuttle fleet, Russia's Soyuz spacecrafts have become the only way for astronauts to reach the ISS until at least the middle of the decade.
