Eating too much meat often makes the headlines, whether the risk of doing so is equated to smoking or cited as the cause of rising diabetes rates.

The price of solar energy in the U.S. continues to fall substantially, according to the latest editions of two annual reports. A third report shows that local permitting and other regulatory procedures can significantly impact residential photovoltaic prices.
Think the flu's only a big threat to kids and seniors? Influenza hospitalized a surprisingly high number of young and middle-aged adults last winter— and this time around, the government wants more of them vaccinated.
Have you ever have the burger vs. salad debate at your favorite fast food joint? When it comes to your health, this seems like a simple decision, but a deeper look at the Nutrition Facts from each restaurant could change your mind.
Like everything else in the body, the white-matter fibers that allow communication between brain regions also decline with age. In a new study, researchers found a strong association between the structural integrity of these white-matter tracts and an older person’s level of daily activity.
Using artificial sweeteners may set the stage for diabetes in some people by hampering the way their bodies handle sugar, suggests a preliminary study done mostly in mice. The researchers and outside experts said more study is needed, while industry groups called the research limited and said other evidence shows sweeteners are safe and useful for weight control.
People living in Hong Kong’s towering skyscrapers may be away from the hustle and bustle of its notorious traffic-snarled streets, but the effects of traffic emissions should not be ignored, according to researchers who are investigating how much of the toxic exhaust fumes at street level are, in fact, still reaching residents living inside high-rise buildings hundreds of feet above.
Computer-driven cars have been testing their skills on California roads for more than four years— but until now, the DMV wasn't sure just how many were rolling around. That changed this week, when the agency issued testing permits that allowed three companies to dispatch 29 vehicles onto freeways and into neighborhoods— with a human behind the wheel in case the onboard computers make a bad decision.
Waist circumference is a simple measure of total and intra-abdominal body fat. The prevalence of abdominal obesity and average waist circumference increased among U.S. adults from 1999 to 2012.
Starting next month, America's remaining tobacco growers will be totally exposed to the laws of supply and demand. The last buyout checks, totaling about $916.5 million, go out in October to about 425,000 tobacco farmers and landowners. They're the last holdovers from a price-support and quota system that had guaranteed minimum prices for most of the 20th century.
Taking a cue from an American TV program, the Chinese city of Chongqing has created a smartphone sidewalk lane, offering a path for those too engrossed in messaging and tweeting to watch where they're going.
The American strategy on Ebola is two-pronged: step up desperately needed aid to West Africa and, in an unusual step, train U.S. doctors and nurses for volunteer duty in the outbreak zone. Amid criticism that the world still is not acting fast enough against the surging Ebola epidemic, Pres. Obama travels today to the CDC to discuss the outbreak with health officials who've been there.
Jeanne Calment, who died in 1997 at the age of 122, remains the oldest person on record. One might assume that she led a faultless, healthy lifestyle. Not at all. Instead, scientists have discovered that longevity is prevalent in certain families and the focus is now on discovering the genes— or the DNA instructions— that favor a long, healthy life.
Cuba's health ministry said today that it is sending more than 160 health workers to help stop the raging Ebola outbreak in Sierra Leone, providing a much-needed injection of medical expertise in a country where health workers are in short supply. World Health Organization chief Margaret Chan said the agency was extremely grateful for the help.
Two engineering students were so chilled by the polar vortex last winter that they decided to take matters into their own hands by inventing the world's first intelligent, heated base layer. In just six months, the pair founded a company, FuelWear, and created a feather-light, washable and snuggly undershirt they call the Flame Base Layer.
There is hardly a spot on the planet where manmade noise doesn’t mix with— or intrude on, from another perspective— the sounds of the natural world. Eventually, one professor says, the only way people may be able to hear nature on its own terms is through an artificial digital world, much like “Star Trek.”
From Apple's new smartwatch that tracks heartbeats to contact lenses that measure blood sugar— Silicon Valley is pouring billions into gadgets and apps designed to transform health care. But the tech giants that have famously disrupted so many industries are now facing their own unexpected disruption: regulation.
Doctors in many U.S. hospitals are unnecessarily prescribing multiple antibiotics for several days when just one would do the job. Health officials have sounded alarms that overuse of antibiotics is helping to breed dangerous bacteria that are increasingly resistant to treatment.

Little is known about the environmental and public health impact of certain natural gas extraction techniques— including hydraulic fracturing, also known as fracking— that occur near residential areas. Now, a study has found a greater prevalence of health symptoms reported among residents living close to natural gas wells, including those drilled by fracking.
More than half of American adults own a smartphone and almost a third of them “can’t imagine living” without the device. The rapidly evolving landscape of applications has changed the way we socialize, conduct bank transactions, find our way to a friend’s house and track diet and exercise.
