WASHINGTON, Nov. 10 (Xinhua) -- The U.S. Food and Drug Administration (FDA) has sent warning letters to more than 1,200 retailers, the majority of which respond to violations relating to selling tobacco to minors, as part of its ongoing effort to reduce tobacco use among children, the agency announced Thursday in a statement.The FDA said that while most retail establishments have been found to be in compliance with the law, some retailers are still selling cigarettes and smokeless tobacco to minors. Warning letters may be followed by civil money penalties if retailers continue to violate the law."It should worry every parent that 20 percent of U.S. high school students smoke cigarettes," said FDA Commissioner Margaret Hamburg in a statement. "President Obama and the FDA are committed to preventing children from smoking. For many young people, that first cigarette or use of smokeless tobacco will lead to a lifetime of addiction, and for many, serious disease. More than 80 percent of adult smokers begin smoking before 18 years of age. Retailers are vital partners in the FDA's efforts to prevent tobacco use among kids."Obama signed the Family Smoking Prevention and Tobacco Control Act that gives the FDA authority to regulate tobacco products to prevent use by minors and reduce the impact on public health. One of the law's provisions permits the FDA to contract with states and territories to conduct compliance check inspections of tobacco retailers. In 2011, the FDA awarded compliance contracts totaling more than 24 million U.S. dollars to 38 states.The FDA also began inspecting U.S. tobacco product manufacturers in October 2011. This is the first time tobacco product manufacturing facilities have ever been inspected by a federal public health agency.

WASHINGTON, Dec. 21 (Xinhua) -- NASA's Dawn spacecraft has sent around 10,000 pictures of the giant asteroid Vesta back to Earth for the first time since its launch in 2007, the U.S. space agency announced Wednesday.The images were taken from an average altitude of 209 km, the closest the spacecraft can get.From the images, scientists could see Vesta's stippled and lumpy surface in great detail, and its many small craters, grooves, and lineaments. The fine scale of the images highlights small outcrops of bright and dark material.With these new discoveries, scientists believe that studying Vesta can help decode the early history of the solar system.Dawn will maintain its low-altitude orbit for another 10 weeks before moving to a higher orbit for another round of photo-taking.Launched in 2007, the 446 million U.S. dollar project aims at studying the chemical composition of Vesta's surface and probing its interior structure.Dawn will leave Vesta in July next year and arrive at the dwarf planet Ceres in February 2015.

BEIJING, Oct. 13 (Xinhuanet) -- Himalayas may be one of the most potential regions to provide solar power in future, according to a new research by Japanese scientists quoted by media reports Thursday. Deserts are usually regarded as the hotbeds for capturing solar power, but some of the loftiest and coldest regions can receive more energy from the sun than some deserts, said Takashi Oozeki and Yutaka Genchi, authors of the research published in Environmental Science and Technology. To set up solar cells on Himalayas would be challenging. Transmission losses and snowfall should be taken into consideration, said the researchers with the National Institute of Industrial Science and Technology in Japan. Still, the Himalayan region is attractive, because there are large energy demands in the countries nearby."It is near regions with large future energy demands such as China and India," they said.Other cold regions that can receive solar power include Andes of South America and Antarctica, according to the study.

CHANGCHUN, Nov. 13 (Xinhua) -- An infrared camera set up by the World Wildlife Fund (WWF) and forestry authorities in northeast China's Jilin province has captured images of a wild Siberian tiger in the Wanda Mountains.Zhu Jiang, head of the WWF Northeast China Program Office, said Saturday that the photos, taken earlier this month, are the first images of a wild Siberian tiger taken in the mountainous area.He said the evidence consolidates the mountains' role as an important habitat for the endangered species, and reinforces the need for local authorities to tighten protection measures, especially clearing animal traps and improving animal rescue efforts.The agency estimates that there are fewer than 20 wild Siberian tigers remaining in China. They live in mountains in the northeastern Heilongjiang and Jilin provinces.Zhu said animal traps still pose a major threat to the safety of wild Siberian tigers and their prey.A wild Siberian tiger was found dead with a trap around its neck in the city of Mishan, Heilongjiang, in October.A WWF survey found an average of 1.6 traps for every 10 km of distance covered in the Siberian tiger nature reserves in Heilongjiang and Jilin last winter."The WWF hopes to cooperate with local governments to protect Siberian tigers and restore their habitats," Zhu told Xinhua. "We aim to help double the population of wild Siberian tigers in China by 2022, the next Year of the Tiger," he said.
