BEIJING, June 12 (Xinhua) -- China's Supreme People's Court (SPC) on Sunday publicized a judicial interpretation which sets specific rules for the country's courts to order penalties to criminals sabotaging TV and radio facilities.The interpretation said that criminals, whose sabotage causes information block for disaster early warning, rescue and others concern public security, could be convicted three to seven years of imprisonment on the charge of sabotaging TV and radio broadcast facilities.Other circumstances that could be convicted the imprisonment include sabotage that causes malfunction in the broadcast of TV and radio stations, according to the new law.According to statistics with the SPC, there have been more than 5,000 cases of sabotaging cable TV wires and more than 1,000 cases of sabotaging state-owned fiber optic lines and other cases of stealing broadcast facilities since 2006 in China.

WASHINGTON, June 16 (Xinhua) -- Cells in the human body are constantly being exposed to stress from environmental chemicals or errors in routine cellular processes. While stress can cause damage, it can also provide the stimulus for undoing the damage. New research by a team of scientists at the University of Rochester has unveiled an important new mechanism that allows cells to recognize when they are under stress and prime the DNA repair machinery to respond to the threat of damage.Their findings will be published Friday in journal Science. Cells in the human body are constantly being exposed to stress from environmental chemicals or errors in routine cellular processes. While stress can cause damage, it can also provide the stimulus for undoing the damage.The scientists, led by biologists Vera Gorbunova and Andrei Seluanov, focused on the most dangerous type of DNA damage -- double strand breaks. Unrepaired, this type of damage can lead to premature aging and cancer. They studied how oxidative stress affects efficiency of DNA repair. Oxidative stress occurs when the body is unable to neutralize the highly-reactive molecules, which are typically produced during routine cellular activities.The research team found that human cells undergoing oxidative stress synthesized more of a protein called SIRT6. By increasing SIRT6 levels, cells were able to stimulate their ability to repair double strand breaks. When the cells were treated with a drug that inactivated SIRT6, DNA repair came to a halt, thus confirming the role of SIRT6 in DNA repair. Gorbunova notes that the SIRT6 protein is structurally related to another protein, SIR2, which has been shown to extend lifespan in multiple model organisms."SIRT6 also affects DNA repair when there is no oxidative stress," explains Gorbunova. "It's just that the effect is magnified when the cells are challenged with even small amounts of oxidative stress."SIRT6 allows the cells to be economical with their resources, priming the repair enzymes only when there is damage that needs to be repaired. Thus SIRT6 may be a master regulator that coordinates stress and DNA repair activities, according to Gorbunova.

SAN FRANCISCO, July 20 (Xinhua) -- Google announced on Wednesday that it has reached a deal with author J.K. Rowling to launch the series of Harry Potter ebooks on Google's platform.When the series of Harry Potter ebooks launch on Pottermore.com in early October, the bestsellers will be available in the United States via Google eBooks platform, said Google in a blog post.When customers buy a Harry Potter ebook from Pottermore.com, they will be able to choose to keep it in their Google's online library in the cloud, as well as other e-reading platforms.Google said Google eBooks can be read on most devices with a modern browser, through Google apps for iOS and Android smartphones and tablets, and on more than 80 e-readers.Meanwhile, Rowling will continue to issue announcements via YouTube, as she announced Pottermore.com in June.The two sides also agreed to make Google Checkout the preferred third-party payment platform for all purchases made on Rowling's Pottermore.com.Pottermore.com, which will be launched on July 31, will sell ebook and audiobook versions of the seven Harry Potter novels, as well as additional content including background details and settings.According to The Times, the Harry Potter brand value is estimated to be more than 15 billion U.S. dollars. The deal could make Google move some e-reader customers from competitors like Amazon, whose e-reader Kindle does not support Google eBooks.

  

BEIJING, Aug. 12 (Xinhuanet) -- The risk of developing coronary heart disease is 25 percent higher for women smokers compared with men, according to a study published in the British medical journal "The Lancet".The authors say this could be due to the physiological differences between the sexes with cigarette smoke toxins having a more potent effect on women.The study by Dr Rachel R Huxley from the University of Minnesota and Dr Mark Woodward from Johns Hopkins University involved a meta-analysis of around four million individuals and 67,000 coronary heart disease events from 86 studies.The researchers found that the pooled adjusted female-to-male relative risk ratio (RRR) of smoking compared with not smoking for coronary heart disease (CHD) was 1.25 (25 percent) higher for women.This RRR increased by 2 percent for every additional year of follow-up, meaning that the longer a woman smokes, the higher her risk of developing CHD becomes compared with a man who has smoked the same length of time.The authors say, "The finding lends support to the idea of a pathophysiological basis for the sex difference. For example, women might extract a greater quantity of carcinogens and other toxic agents from the same number of cigarettes than men. This occurrence could explain why women who smoke have double the risk of lung cancer compared with their male counterparts."Worldwide, there are 1.1 billion smokers, of whom a fifth are women.According to the Tobacco Atlas, India, with around a crore female smokers, ranks third in the top 20 female smoking populations across the globe, only the U.S. with 2.3 crore female smokers and China with 1.3 crore female smokers, are worse off.
