Cancer cells are survival artists with a strong criminal streak. They surround themselves with a protective shield of extra-cellular material and then secure supply lines by attracting new blood vessels.

In a new study, Valter Longo and his colleagues show that cycles of a four-day low-calorie diet that mimics fasting (FMD) cut visceral belly fat and elevated the number of progenitor and stem cells in several organs of old mice—including the brain, where it boosted neural regeneration and improved learning and memory.

In a quest for a perfect tan, many people – especially young white women between age 18 and 25 – may head to a tanning salon, using tanning booths, sunbeds and sunlamps to kick-start their tan. Others (including people who are more prone to burn instead of tan) may head to the salon to slowly develop a “base tan,” with the mistaken belief that it will prevent a sunburn.

The effects of postnatal depression on children’s emotional development can be profound. These children have more mental health and behavioural problems as they grow up. And in low-income countries, the effects of maternal depression extend to higher rates of childhood stunting and physical illness.

I can’t promise perfect health any more than I could promise a life without problems. That’s not what life seems to be about. Instead, I am offering you another way to look at your health, and your life, that takes you out of helpless victim mode and reminds you that you are in charge.

Six percent of adult New Yorkers who have a tattoo say they have suffered from a related rash, severe itching, or swelling that lasts longer than four months and in some case for many years.

“When we think about quality of life for older adults, and improving quality of life, it seems like targeting the individual is only part of the story, and our findings suggests that for older adults, a larger part of individual well-being is defined by our partner’s health and cognitive functioning as well,” says David Sbarra, associate professor of psychology at the University of Arizona.

We’ve known for some time that too much sitting increases your risk of diabetes, certain cancers, heart disease and early death. But until now it’s been unclear how much standing during the work day may counter this increased risk.

A new study adds more proof, showing that seniors who are very social have better lung function, which tends to decrease as we get older. In fact, researchers found that the more social roles people engaged in, the better their lungs functioned.

Some like it hot, some like it iced, and some just don’t like it at all. Until recently, coffee was on the list of habits to break if you really wanted to be healthy.

If your child is overweight when they start school at the age of six, unless you do something about it at that point, the indications are that they are going to be overweight teenagers and obese adults. Evidence has shown that overweight children and teenagers have a greater risk of developing lifestyle diseases such as type 2 diabetes, hypertension and cardiovascular disease later in life - and dying prematurely.

Most people are acutely aware of the toll the heat can take on human life, particularly since the extreme heat of Black Saturday in 2009 and the European heatwave of 2003. So it may come as a surprise that more Australians die from the cold than the heat.

The demand for bottled water it seems is booming. Canadean, a market research company specialising in the beverage industry recently reported the remarkable growth in global sales of bottled water. With an average annual growth of 6% since 2008 it looks as though water will, for the first time, overtake sales of soft drinks by 1.3% this year.

I recently wrote about the terrible sleep habits of the characters in House of Cards. I disapproved of Frank Underwood’s late-night computer work in the Oval Office, his new midnight iPad gaming habit and Claire taking her laptop to bed with her.

Elevated blood sugar can rapidly increase levels of amyloid beta, a key component of brain plaques in Alzheimer’s patients, a new study shows. The buildup of plaques is thought to be an early driver of the complex set of changes that Alzheimer’s causes in the brain.

A growing body of advice suggests doing small amounts of moderate exercise can make a significant difference to your health. Academic research is being turned into headlines such as: “Spending two minutes an hour walking instead of sitting can help you live longer” and “Can’t be bothered to exercise? Just WALK”.

A dollop of peanut butter and a ruler might be a way to confirm a diagnosis of early-stage Alzheimer’s disease. Jennifer Stamps, a graduate student in the McKnight Brain Institute Center for Smell and Taste and the University of Florida, came up with the idea of using peanut butter to test for smell sensitivity when she was working with Kenneth Heilman, a professor of neurology at the University of Florida.

Picture this scenario: Seven days ago you had a really bad attack of back pain. You can hardly get out of bed, and getting dressed and in and out of the car is slow and painful. It’s making life seem miserable. You’re middle-aged but, other than this pain, are well.

I began experimenting with the tuning forks with a few of my massage therapy clients. I found that if a client was complaining of pain in a particular area, the fork would produce either a loud, sharp tone or a tone full of static and “noise.” After holding the fork over the area, I found that after a few moments the tone would become clear...

Have you ever wondered what those food additive numbers in the ingredients list on your food packaging meant and what they were really doing to your body? A recent study suggests emulsifiers – detergent-like food additives found in a variety of processed foods have the potential to damage the intestinal barrier, leading to inflammation and increasing our risk of chronic disease.

Can organic farmers use Roundup® ? I get that question a lot. Society has been told and, it seems, really believes, that as crop chemicals go, nothing could be safer. But that's just it, using nothing is safer.

In the United States, we live in a nation where hunger and obesity go hand in hand. More than 17 million US households struggle to put food on the table, and when they do, it’s often high in fat and sugar because healthy options are scarce in low-income neighborhoods.

In a study published last week, researchers at Harvard University examined 21 brands of dietary supplements containing an herbal stimulant called Acacia rigidula. More than half of the brands analyzed contained an untested amphetamine isomer called ?-methylphenylethylamine (BMPEA).
