SAN FRANCISCO, Sept. 12 (Xinhua) -- Amazon.com Inc. is talking with book publishers to launch a rental subscription service for digital books, U.S. media reported on Monday.Several publishing executives said they aren't enthusiastic about the idea because it could lower the value of books and it could also strain their relationships with other retailers that sell their books, The Wall Street Journal quotes people familiar with the matter in a report.The Seattle-based company is considering a digital book library featuring old titles, which would be available to Amazon Prime subscribers, who currently pay 79 U.S. dollars a year for access to digital library of movies and TV shows and unlimited two-day shipping, said the report.Amazon would offer book publishers a substantial fee and could limit the amount of books that Amazon Prime customers could read for free every month, the report cited some sources as saying.The online retailing giant makes the popular electronic reader Kindle and is also reported to launch a color touchscreen tablet before October to compete with Apple's iPad and other devices in the increasingly crowded tablet computer market.The proposal is another sign that retailers are looking for more ways to deliver content digitally as customers increasingly read book and watch TV on personal computers, tablets and other electronic devices, said The Wall Street Journal report.

BEIJING, July 22 (Xinhuanet) -- Regulation is needed to govern rapidly expanding research in animals containing human tissue or genes, according to the Britain's Academy of Medical Sciences.Using animals with limited humanized traits is not new. Genetically engineered mice containing human DNA are already a mainstay of research into new drugs for diseases like cancer.For instance, Chinese scientists have already introduced human stem cells into goat fetuses and U.S. researchers have studied the idea of creating a mouse with human brain cells.But Martin Bobrow, a professor of medical genetics at the University of Cambridge, who led the Academy's working group, said there were three areas of particular concern."Where people begin to worry is when you get to the brain, to the germ cells, and to the sort of central features that help us recognize what is a person, like skin texture, facial shape and speech," he said.His report recommends that government should put in place a national expert body, working within the existing system for regulating animal research, to oversee such sensitive areas.British ministers said they welcomed the report and would consider its recommendations carefully.

KATSINA, Nigeria May 31 (Xinhua) -- At least 10 secondary school teachers are reported to have died of food poisoning, and several others hospitalized in northern Nigeria's Katsina State, the News Agency of Nigeria reported on Tuesday.The incident occurred at the weekend at a workshop organiZed by the state Ministry of Education for some 650 teachers at Government Day Secondary School (GDSS), Kofar Yan'daka, Katsina.The report said soon after taking their lunch, supplied by a popular corporate caterer on the fateful day, some of the teachers were vomiting and afflicted by diarrhoea, as a result of which they were rushed to the Federal Medical Center, Katsina and the Police Clinic for medication.Ten of the affected teachers were said to have died as a result of the infection.State police spokesperson Abubakar Ibrahim confirmed the incident to reporters.He said only one teacher died, while 19 others were hospitalized.He said 12 of the affected teachers had already been discharged from the hospitals, while seven others were still on admission at the Federal Medical Center and Katsina Police Clinic.He said the police had already collected sample of the food supplied by the caterer for clinical analysis.

MOSCOW, June 15 (Xinhua) -- Russia's Mission Control announced on Wednesday it had raised the International Space Station (ISS) by 10.2 km to 374.7 km with the help of the Europe's ATV-2 Johannes Kepler.The Mission Control conducted the correction to the ISS at 19: 55 Moscow time (1555 GMT) by the boosters of the ATV-2 Johannes Kepler. The correction had lasted for some 40 minutes.According to the Mission Control, the correction was made in line with the ISS's ballistic flight program.On June 12, the Europe's second Automated Transfer Vehicle (ATV) Johannes Kepler has conducted two similar operations, raising the ISS orbit by 19.2 km to 364.6 km.Corrections to the space station's orbit are conducted periodically before launches of Russian cargo ships and U.S. shuttles to compensate for the Earth's gravity and to safeguard successful dockings.According to the Mission Control, the ATV-2 Johannes Kepler is scheduled to undock from the ISS on June 21.

BEIJING, Aug. 15 (Xinhua) -- Scientists in a lab with Daya Bay Nuclear Power Station in southern Guangdong Province have found neutrino through two detecting instruments, which is likely to provide clues to solving the mystery of why there is more matter than antimatter in the universe.The Institute of High Energy Physics with the Chinese Academy of Sciences on Monday announced the breakthrough that was achieved by more than 250 researchers from six countries and regions.The two neutrino detectors are installed underground 360 meters away from the nuclear plant at a depth of 100 meters.Scientists believe that matter and antimatter were created in equal amounts during the Big Bang, but the disappearance of antimatter remains a mystery.Neutrino is an elementary particle that is able to pass through ordinary matter almost unaffected, which makes it extremely difficult to detect.Located in Shenzhen, a city neighboring Hong Kong, the Daya Bay Nuclear Power Station commenced operation in 1993.Scientists from the Chinese Academy of Sciences and the U.S.-based Brookhaven National Laboratory and the Lawrence Berkeley National Laboratory started the underground neutrino experiment in 2006.Kam-Biu Luk, spokesman for the laboratory, said that the results of the experiment would further shed light on the evolution of basic matter after the Big Bang.The neutrino experiment in the Daya Bay is one of the largest cooperation projects with regards to basic research between China and the United States.Among the participants of the experiment are Russia, Czech Republic, and China's Hong Kong and Taiwan regions.
