This is Special English. I’m Mark Griffiths in Beijing. Here is the news.The recent WannaCry ransom ware outbreak across the world is the latest alarm about cyber security that demands immediate efforts at different levels, including international cooperation.It has been found that measures as simple as official Microsoft patch installation and security software update can work to fend off WannaCry in the largest cyber-attack in more than a decade. The hacking highlights the need for Internet users to heighten cyber security awareness.However, it also calls for systematic efforts as well as international cooperation to tackle cross-border challenges in a digitally connected world in order to affect a universal defense.A senior research fellow on cyber policy and security at Stanford University told the Xinhua News Agency that international cooperation on cyber security will be essential for a safer and more secure cyberspace.Herb Lin deplored the fact that countries have different views on how they intend to use cyberspace and the rules they want to apply have so far made it difficult to achieve international cooperation.Some experts foresee more attacks like WannaCry, which has hit more than 200,000 computers in some 150 countries since May 12. The vast majority of successful hacks require only the most basic techniques.This is Special English.Pharmaceutical company Merck recently won approval from the China Food and Drug Administration to sell its human papillomavirus vaccine, Gardasil, to help women fight cervical cancer.Developed by the US-based company in 2006, the vaccine has proved effective in protecting against the virus, better known as HPV, the chief cause of cervical cancer. The virus is found in almost all cervical cancer cases.Gardasil is the first HPV vaccine in the world and the second to be licensed for use in China.In July, Cervarix, an HPV vaccine developed by pharmaceutical GlaxoSmithKline, received approval to be sold on the Chinese mainland after almost 10 years of seeking approval.Gardasil is expected to be commercially available on the mainland in three to six months, which means women will no longer have to seek vaccinations outside of the mainland, in places such as Hong Kong.After breast cancer, cervical cancer is the second-most common cancer in women aged between 15 and 44 in China. China reports more than 130,000 cervical cancer cases a year, accounting for 28 percent of the global total.The HPV vaccine, as the first anti-cancer vaccine in the world, has proved effective in preventing cervical cancer and is seen as a breakthrough in the fight against the condition.Today, such vaccines are in use in around 120 countries and regions, including the United States, Australia and most European countries.You&`&re listening to Special English.

That’s according to researchers from the University of Adelaide and the South Australian Health and Medical Research Institute. The often overlooked historical technique, which involves "flushing" the woman&`&s fallopian tubes with iodised poppy seed oil, has been proven to be successful in aiding fertility.Research teams in Australia and the Netherlands say that the procedure, called HSG, was first carried out in 1917 and involved flushing the tubes with the oil during an X-ray. Professor Ben Mol from the University of Adelaide says that over the past century, pregnancy rates among infertile women reportedly increased after their tubes had been flushed with either water or oil during the X-ray procedure. Until now, it has been unclear whether the type of solution used in the procedure was influencing the change in fertility.He said the results have been even more exciting than s
