BEIJING, March 11 (Xinhuanet) --Women who have a cup or more of coffee everyday may reduce their risk of stroke by as much as 25 percent, according to a new study in the Journal Stroke Thursday. This study, led by Swedish researcher Susanna Larsson of the Karolinska Institute in Stockholm, followed more than 34,000 Swedish women aged 49 to 83 who were free of heart disease. After 10-year of follow-up, there were 1,680 strokes, and the study found that those who drank at least one cup of coffee each day had a 22 to 25 percent lowered risk of stroke, compared with women who drank less.The study further suggested coffee can help prevent cognitive decline and can boost vision and heart health. It is also related to a reduced risk of liver cancer."We used to worry that (coffee) raises blood pressure and causes increased heart rate, but it appears to be less risky than we thought," said physician Claudette Brooks, spokesperson for the American Stroke Association. Now, exactly what it is about coffee that may lower stroke risk is unknown. But the researchers speculated that coffee might reduce inflammation, lower oxidative stress and help make the body more responsive to insulin.However, some experts kept skeptical about the real impact coffee would have on reducing the incidence of stroke."The problem with this type of study is that there are too many factors unaccounted for and association does not prove causality," Dr Larry B. Goldstein, director of the Duke Stroke Center at Duke University Medical Center said."Subjects were asked about their past coffee consumption in a questionnaire and then followed over time. There is no way to know if they changed their behavior," Goldstein added.In any case, the good news for coffee junkies is that at least drinking coffee don't increase women's risk of stroke.

SAN FRANCISCO, May 3 (Xinhua) -- Apple Inc. announced on Tuesday that it has updated its iMac all-in-one desktop, adding Intel's next generation quad-core processors, Thunderbolt data ports and a new HD camera.Starting at 1,199 U.S. dollars, the new iMac is up to 70 percent faster and its new graphics deliver up to three times the performance of the previous generation, Apple said in a statement.The new iMac features quad-core Intel Core i5 processors with an upgrade option to Core i7 processors.The 21.5-inch model has a single Thunderbolt port while the 27- inch has two, in addition to four USB 2.0 inputs and a FireWire 800 port.Thunderbolt, which debuted with Apple's updated MacBook Pro notebooks in February, is also an Intel design bringing together high-speed data transfer and high-definition display onto a single cable. It can transfer a full-length HD movie in less than 30 seconds with a speed of 10 gigabits per second, which is twice the speed of USB 3.0, 12 times faster than FireWire 800 and up to 20 times faster than USB 2.0.The new iMac also includes a built-in FaceTime HD camera, which supports high-definition video calls, Apple said.

LOS ANGELES, April 7 (Xinhua) -- Unrecycled energy-efficient bulbs release tons of mercury into the environment every year, raising an environmental concern, it was reported on Thursday.Demand for the energy-efficient lights -- the compact fluorescent light bulb (CFL) -- is growing as government mandates for energy-efficient lighting take effect, yet only about two percent of residential consumers and one-third of businesses recycle the new bulbs, the Los Angeles Times said, quoting the Association of Lighting and Mercury Recyclers (ALMR).Each CFL contains up to five milligrams of mercury, a potent neurotoxin that's on the worst-offending list of environmental contaminants, the report said.As a result, U.S. landfills are releasing more than four tons of mercury annually into the atmosphere and storm water runoff, the Journal of the Air and Waste Management Association said in a study published by the paper.The federal Clean Energy Act of 2007 established energy- efficiency standards for light bulbs that dimmed the future for old-fashioned incandescents, which don't meet those standards. Incandescents are to be phased out by 2014 in the U.S., and California passed even stricter rules, calling for store shelves to be cleared of them by 2013.The old-style bulbs are just too wasteful, converting to light only 10 percent of the energy they consume. The rest is squandered as heat.Sales of energy-efficient alternatives like CFLs, halogen bulbs and LEDs have been growing steadily, with the low-cost CFLs the biggest sellers, according to the paper.If every California household replaced five incandescent bulbs with CFLs, the move would save 6.18 billion kilowatt-hours and prevent the annual release of 2.26 million tons of heat-trapping carbon dioxide, according to the California Energy Commission. That 's equivalent to taking 414,000 cars off the road.But no federal law mandates recycling of household fluorescent lights. Federal rules exempt some businesses, based in part on the number of bulbs used, said Paul Abernathy, executive director of the ALMR, which is based in Napa, Calif.Several states, including California, Massachusetts, Maine, Vermont and Minnesota, do require that all households and businesses recycle fluorescents, the paper said.But the ALMR said compliance is low because of a lack of convenient drop-off options.
