SAN FRANCISCO, April 5 (Xinhua) -- Apple Inc.'s iPad 2 has topped the ratings by Consumer Reports, an influential U.S. magazine for product reviews, in the latest tests of the 10 most- promising tablet computers.According to the ratings released on Tuesday, the Apple iPad 2 with Wi-Fi plus 3G (32G), which is priced at 730 U.S. dollars, topped the ratings, scoring "excellent" in nearly every category.Besides several models from Apple, other brands tested include Archos, Dell, Motorola, Samsung and Viewsonic. Each tablet was evaluated on 17 criteria, including touch-screen responsiveness, versatility, portability, screen glare and ease of use."So far, Apple is leading the tablet market in both quality and price, which is unusual for a company whose products are usually premium priced," Paul Reynolds, electronics editor at Consumer Reports, said in a statement.The Motorola Xoom, whose price is 800 dollars, stood out as the iPad 2's main rival. It boasts several features that the iPad lacks, including a built-in memory card reader and support for the Flash videos.The first-generation iPad, priced at 580 dollars, also outscored many of the other models tested but tied with the Motorola Xoom, according to tests by Consumer Reports.

WASHINGTON, May 3 (Xinhua) -- People diagnosed with asthma in the United States grew by 4.3 million between 2001 and 2009, according to a new report released Tuesday by the Centers for Disease Control and Prevention (CDC).In 2009, nearly one in 12 Americans were diagnosed with asthma. In addition to increased diagnoses, asthma costs grew from about 53 billion U.S. dollars in 2002 to about 56 billion dollars in 2007, about a six percent increase. The explanation for the growth in asthma rates is unknown, according to the CDC.Asthma is a lifelong disease that causes wheezing, breathlessness, chest tightness, and coughing, though people with asthma can control symptoms and prevent asthma attacks by avoiding things that can set off an asthma attacks, and correctly using prescribed medicine, like inhaled corticosteroids. The report highlights the benefits of essential asthma education and services that reduce the impact of these triggers, but most often these benefits are not covered by health insurers."Despite the fact that outdoor air quality has improved, we've reduced two common asthma triggers -- secondhand smoke and smoking in general -- asthma is increasing," said Paul Garbe, chief of CDC 's Air Pollution and Respiratory Health Branch. "While we don't know the cause of the increase, our top priority is getting people to manage their symptoms better."Asthma triggers are usually environmental and can be found at school, work, home, outdoors, and elsewhere and can include tobacco smoke, mold, outdoor air pollution, and infections linked to influenza, cold-like symptoms, and other viruses.According to the report, asthma diagnoses increased among all demographic groups between 2001 and 2009, though a higher percentage of children reported having asthma than adults (9.6 percent compared to 7.7 percent in 2009). Annual asthma costs in the United States were 3,300 dollars per person with asthma from 2002 to 2007 in medical expenses. About two in five uninsured and one in nine insured people with asthma could not afford their prescription medication."Asthma is a serious, lifelong disease that unfortunately kills thousands of people each year and adds billions to our nation's health care costs," said CDC Director Thomas Frieden. "We have to do a better job educating people about managing their symptoms and how to correctly use medicines to control asthma so they can live longer more productive lives while saving health care costs."

BEIJING, Feb. 5 (Xinhua) -- China's railways transported about 77.34 million passengers during the fifteen days (Jan. 19 to Feb. 2) before the Spring Festival, the Ministry of Railways said.The figure was about 9.5 percent higher than the same period last year and set a new record, according to a report posted on the ministry's website.There were an average of 5.16 million passengers per day, up 448,000 from the same period last year. On Jan. 29, passengers topped 5.78 million, setting a new record for daily transportation before the Spring Festival, the report said.In the fifteen days before the festival, about 4.80 million passengers left Beijing, 8.39 million left Guangzhou and 5.69 million left Shanghai, while year-on-year growth and those leaving Guangzhou rose the most, up 15 percent year on year, said the report.The ministry said challenges still exist as more snow and rain will hit southern China after the Spring Festival, when passengers are returning.China's busy Spring Festival transportation season runs for 40 days and is calculated in two phases: 15 days before the Spring Festival and 25 days after the Spring Festival, the report explained.

BEIJING, May 4 (Xinhuanet) -- No formalin has been found in the milk powder imported from S. Korea into China due to different milk sources, the general agency of South Korea's Maeil Dairies said Tuesday.The declaration came after Maeil Dairies, South Korea's third-largest dairy company, was found to have produced milk from cows given feed tainted with formalin.The agency said that the milk used in the dairy products exported to China comes from New Zealand, Europe and other places outside South Korea, so Chinese consumers should have nothing to worry about.Formalin, a liquid form of formaldehyde gas, was largely used in the past as a disinfectant, pesticide and bactericide for preservation of biological specimens.Its use has dwindled over the years due to health concerns.After the incident, South Korea has decided to conduct emergency inspections on milk sold in the market by four major dairy companies, to check the presence of formalin.

SAN FRANCISCO, May 26 (Xinhua) -- Internet advertising revenues in the United States surged to 7.3 billion U.S. dollars in the first quarter of 2011, the highest first-quarter revenue level on record for the industry, said a new report released on Thursday.The numbers also represented a 23-percent increase over the same period a year earlier, the Interactive Advertising Bureau ( IAB) and PricewaterhouseCoopers said in the report."The consistent and considerable year-over-year growth we're seeing demonstrates that digital media is an increasingly popular destination for ad dollars, and for good reason," Randall Rothenberg, chief executive officer of the IAB, said in a statement."As Americans spend more time online for information and entertainment purposes, digital advertising and marketing has emerged as one of the most effective tools businesses have to attract and retain customers," he added."These numbers indicate that the interactive advertising field hasn't simply bounced back since the recession; it's growing with dynamic energy," noted David Silverman, a partner at PricewaterhouseCoopers.IAB, a trade association for interactive marketing, comprised more than 500 media and technology companies who are responsible for selling 86 percent of online advertising in the United States.
