PARIS, Aug. 19 (Xinhua) -- Marine scientists and representatives from the private sector and military establishments would meet at UNESCO at the end of this month to measure noise's impact on marine life, the Paris-based UN scientific branch UNESCO said Friday.The main agenda of the meeting, which is due from Aug. 30 to Sep. 1, was to discuss the program of the International Quiet Ocean Experiment (IQOE)."This decade-long project aims to fill the considerable knowledge gaps in this area, so that management of ocean noise can be more informed and effective," UNESCO said in a statement.The Quiet Ocean Experiments was initiated against the background that human activities on the high seas have increased significantly in recent decades, and resulted in impact upon many marine species relying mainly on sound to communicate.However, some sounds are suspected to alter the behavior of marine animals. For example, several whale species have raised the volume of the squeaks, clicks and moans by which they communicate with each other.The experiment is organized by the Scientific Committee on Oceanic Research (SCOR) and the Partnership for Observation of the Global Oceans (POGO), of which UNESCO's Intergovernmental Oceanographic Commission (IOC) is a member.
SINGAPORE, Sept. 7 (Xinhua) -- Singapore scientists have found possible new ways to treat a type of aggressive breast cancer that is unresponsive to current forms of treatment, local broadcaster Channel NewsAsia reported on Wednesday.The team of scientists at the Genome Institute of Singapore ( GIS) and National University of Singapore (NUS), led by GIS senior group leader Qiang Yu, found that the enzyme EZH2 acts by inhibiting genes that stop the growth of tumors in the body.The insights could open the door to developing more effective treatment for fast spreading breast cancers, especially the estrogen receptor-negative breast cancer that is common all over the world.It was also found that through EZH2, cancer is promoted in the body by activating specific genes that impact breast cancer progression and cancer stem cell self-renewal.Yu said the new understanding on how EZH2 works as a cancer- causing gene in breast cancer has important therapeutic implication."The results suggest that small molecule drugs that block enzyme activity of EZH2 may not work for cancers caused by EZH2's activation genes," Yu said.Currently pharmaceutical companies have been developing drugs only to the block EZH2 enzyme activity so that tumor suppressers can perform their protective role in blocking cancer growth.Researchers said the next step would be to develop biomarkers to identify tumors with EZH2.This step would enable better treatment methods, with one of options being the development of therapies that shut down EZH2 completely and not just inhibit its enzymatic function.The findings have been published on the journal Molecular Cell.

SAN FRANCISCO, July 12 (Xinhua) -- Facebook and Time Warner announced on Tuesday that they are teaming up to launch a wide- ranging, major cross-platform partnership initiative to fight bullying.The multi-media campaign, named "Stop Bullying: Speak Up" after the original anti-bullying initiative by Time Warner's Cartoon Network, will integrate broadcast, print, online and social media to educate parents, teachers and youth about the actions that will help protect young people from the impact of bullying, the two said in a joint statement.As part of the initiative, Facebook is scheduled to launch an interactive application in the back-to-school season this fall, which will enable educators, parents, and kids to make a personal commitment to help stop bullying."We care deeply about the safety of our nation's children and are proud to be partnering with Time Warner to raise awareness of bullying," Sheryl Sandberg, Facebook's chief operating officer, said in the statement."We believe that by working together with parents and teachers, we can teach young people to speak up and stop bullying," she added.Time Warner is also planning to expand its multiplatform efforts to communicate the anti-bullying message to an broader audience.It said in October, three of its magazines -- People, Sports Illustrated and Time -- and their affiliated websites will feature editorial content that highlights the problem of bullying and innovative programs and measures being taken to combat it.In partnership with Facebook, CNN's Anderson Cooper will also host a new town hall, which is scheduled to air in October and will be dedicated to discussing bullying issues confronting kids today as well as discussions with experts to teach adults on coping with the bullying epidemic."I'm confident that through our multiplatform approach and combined resources we can inspire even more people to take action against bullying," said Jeff Bewkes, Time Warner's chairman and chief executive officer.
BERLIN, June 14 (Xinhua) -- A two-year-old boy became the first child to be killed by the deadly E. coli in Germany on Tuesday, officials said.To date, the terrifying EHEC infection has claimed 36 lives in Germany and one in Sweden.The child, from the northern town of Celle, died in hospital in Hanover of kidney failure and abnormal breakdown of red blood cells, two extreme symptoms of the infection with enterohaemorrhagic E. coli (EHEC), authorities in the state of Lower Saxony said.The boy became the youngest known fatal victim since the outbreak of E. coli in May. His father and 10-year-old brother were also infected with the deadly bacteria, but are recovering, doctors told a local newspaper.The Robert Koch Institute, Germany's national disease prevention and control agency, said on Tuesday that a total of 3, 235 cases had been reported in the country. Among them, 782 people are suffering from haemolytic uraemic syndrome (HUS), a life- threatening illness arising from E. coli, which would destroy human kidney and nervous system.The institute added that the number of new infections is declining sharply in recent days, with only seven reported on Tuesday.German authorities announced on Friday that bean sprouts from a farm in northern Germany were one source of the outbreak, and dropped the previous warning against eating raw cucumbers, tomatoes and lettuce. However, the food panic has caused losses worth hundreds of millions of dollars for European farmers.
BEIJING, Aug. 16 (Xinhuanet) -- Almost one in four Chinese students aged between 12 and 14 have tried smoking, according to the results of a survey released by the Chinese Association on Tobacco Control (CATC).The survey, carried out among 38,839 students and 6,503 teachers from middle and high schools in 11 provinces across the country between May and June, showed that 22.5 percent of students aged between 12 and 14 had tried smoking and that 15.8 percent of middle and high school students smoke regularly."There are definitely quite a number of boy students in my class who smoke regularly as some have been found smoking outside campus during lunch break," said Li Xiaolan, an English teacher from a high school in Shanghai. The survey also found that 39 percent of students took their first cigarette from their classmates."It was quite common to smoke with my classmates at school and we usually smoked in toilets or in corners of the playground after lunch," said Zhou Guangrong, a 22-year-old university student from Guiyang, Guizhou province, who started smoking when he was 12.The majority of student smokers buy cigarettes themselves and about 76 percent of the adolescent smokers said that there is at least one cigarette shop within 200 meters from their school."When I was a student at middle and high schools, they were surrounded by cigarette shops," said Zhou who used to smoke two cigarettes per day in primary school and two packs per week in middle and high school."We're keen to show that more adolescents are starting smoking much younger than before, and that we need to minimize the number of young smokers," said Duan Jiali, secretary-general of the youth tobacco control commission under CATC. Duan added that teachers and parents should set a good example for teenagers by not smoking in front of them at school or at home, which is the most influential way of stopping adolescents from smoking.China banned smoking in 16 types of public indoor venues - including hospitals, schools, bars, restaurants and hotels - on May 1 in an attempt to curb tobacco use in the country with the world's largest number of smokers.Currently, there are more than 300 million smokers in China, and about 1.2 million people die from smoking-related diseases every year, accounting for one-fifth of the world's total, according to statistics from the World Health Organization."Meanwhile, about 540 million people are exposed to secondhand smoke, 48.9 percent of which are adolescents (from 15 to 19 years old)," said Xu Guihua, deputy director of the CATC."It's essential and urgent for us to control the number of adult smokers who potentially tempt adolescents to smoke."
