BANJUL, June 24 (Xinhua) -- Deputies at the Gambian National Assembly (parliament) on Friday passed a new bill entitled the "Food Safety and Quality Bill 2011".Under the new act, food operators are obliged to ensure food safety, quality production, processing and distribution within the business under their control and that their products must satisfy the requirements and regulations as demanded.Submitting the motion before deputies, Vice President and Minister for Women Affairs Isatou Njie-Saidy warned that the well- being of "our citizenry is at stake.""Giving our continuous drive to place health care on top of our development agenda, we call on all and sundry to join the bandwagon in the implementation of this bill," she said.She told deputies that the bill and the establishment of the Gambia Food Safety and Quality Authority is consistent with the regulation worked out by the West African bloc ECOWAS on the health and safety of plants, animals and food in the region.The Gambia Food Safety and Quality Authority being established by this bill will be the sole national competent authority having unitary responsibility for food safety and quality, she declared."In order to achieve the general objectives of a high level of protection of human health and life, measures applied under this Act shall be based on risk assessment," she added.

XICHANG, Sichuan, Aug. 12 (Xinhua) -- China launched a communications satellite PAKSAT-1R for Pakistan at 0:15 a.m. Friday from the Xichang Satellite Launch Center in southwest China's Sichuan Province.The satellite was carried by a Long March-3B carrier rocket, according to the launch center. It is China's first in-orbit delivery to Asian customers and also the first commercial satellite export to international users this year.According to statistics from the control center, the satellite successfully separated from its carrier rocket and entered geostationary transfer orbit as scheduled, 26 minutes after being launched.PAKSAT-1R will provide a range of services, including broadband Internet, telecom and broadcasting, covering some regions of Europe, South Asia, the Middle East, and the eastern Africa.The contract for the PAKSAT-1R was signed in 2008 between China Great Wall Industry Corporation and the Space and Upper Atmosphere Research Commission of Pakistan.China and Pakistan share a long history of space technology cooperation. Pakistan's first low-orbit satellite, BADR-A, was launched by China in 1990 with Long March 2E rocket.

SAN FRANCISCO, Sept. 9 (Xinhua) -- AOL's chief executive officer (CEO) Tim Armstrong has reached out to Yahoo for talks of a merger of the two companies, U.S. media reported on Friday.Armstrong is discussing options for a combination aimed at strengthening the two Internet companies, Bloomberg quoted two people who are familiar with the matter as saying.The report said that the AOL CEO had been interested in a merger with Yahoo last year but was rejected while Carol Bartz served as Yahoo CEO, who was ousted by Yahoo's board on Tuesday.Reconsidering the option after Bartz's departure, Armstrong has talked with private equity firms and investment bankers from Allen & Co. working with Yahoo.Under one scenario being considered, Yahoo would acquire AOL and Armstrong would become CEO of the combined company, said the source.Both Yahoo and AOL are suffering from declining revenues, struggling to compete against companies like Google and Facebook. Some analysts said that the merger could not provide a long-term solution to the problems the two companies face after they failed to keep up with Internet trends.

LOS ANGELES, July 6 (Xinhua) -- NASA scientists have got the first-ever, up-close details of a Saturn storm that is eight times the surface area of Earth, the Jet Propulsion Laboratory ( JPL) announced on Wednesday.The images were captured by NASA's Cassini spacecraf, according to JPL in Pasadena, Los Angeles.On Dec. 5, 2010, Cassini first detected the storm that has been raging ever since. It appears approximately 35 degrees north latitude of Saturn.The storm is the biggest observed by spacecraft orbiting or flying by Saturn. NASA's Hubble Space Telescope captured images in 1990 of an equally large storm.Pictures from Cassini's imaging cameras show the storm wrapping around the entire planet covering approximately two billion square miles (4 billion square kilometers).The storm is about 500 times larger than the biggest storm previously seen by Cassini during several months from 2009 to 2010. At its most intense, the storm generated more than 10 lightning flashes per second.Cassini has detected 10 lightning storms on Saturn since the spacecraft entered the planet's orbit.Those storms rolled through an area in the southern hemisphere dubbed "Storm Alley." "Cassini shows us that Saturn is bipolar," said Andrew Ingersoll, a Cassini imaging team member at the California Institute of Technology in Pasadena, California. "Saturn is not like Earth and Jupiter, where storms are fairly frequent. Weather on Saturn appears to hum along placidly for years and then erupt violently. I'm excited we saw weather so spectacular on our watch."The new details about this storm complement atmospheric disturbances described recently by scientists using Cassini's composite infrared spectrometer and the European Southern Observatory's Very Large Telescope. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. NASA's JPL manages the mission for the agency's Science Mission Directorate in Washington.

BEIJING, Aug. 22 (Xinhuanet) -- Researchers have discovered how a human egg captures an incoming sperm for fertilization, paving the way to help couples suffering from infertility, according to media reports on Monday.An international team of researchers found that a sugar chain known as the sialyl-lewis-x sequence (SLeX) makes the outer coat of the egg “sticky,” which has proven to be helpful in binding the egg and the sperm.As a result, this observation has filled in a huge gap in the understanding of fertility and provides hope for ultimately helping couples who currently cannot conceive.Scientists and doctors know that a sperm identifies an egg when proteins on the head of the sperm match and bind to a series of specific sugars in the egg’s outer coating. With a successful match of proteins, the outside surfaces of the sperm and egg then bind together before merging, which is then followed by delivery of sperm’s DNA into egg.To identify this molecules, the researchers used ultra-sensitive mass-spectrometric imaging technology to observe and identify which molecules are most likely to be key in the binding process.They experimented with a range of synthesised sugars in the laboratory and found that it is SLeX that specifically binds sperm to an egg.According to the World Health Organisation, infertility affects about 15 percent of reproductive-aged couples around the world and almost one in every seven couples in Britain has problems conceiving a child for various reasons.
