When a child is diagnosed with asthma, parents usually have a number of questions. How serious is asthma? Will the child grow out of it?
The number of new cases of metastatic prostate cancer climbed 72 percent from 2004 to 2013, but it’s unclear whether the rise is due to a recent trend of fewer screenings, the disease becoming more aggressive, or both.
I remember as a child, on the rare warm days that we used to get in Britain, my grandmother telling me to “have a cup of black tea … it will help cool you down”. As a seven-year-old, this seemed like a crazy idea, especially when all I wanted was a cold lemonade and another ice cream.
It should be one of the most relaxing times of the day. You climb into bed, get comfortable and cosy, start to feel your brain slowing down … and then suddenly you experience a shocking falling sensation.
It is an open secret: while athletes dope their bodies, regular office workers dope their brains. They buy prescription drugs such as Ritalin or Provigil on the internet’s flourishing black market to boost their cognitive performance.

If you take prescription opioids, you may have experienced withdrawal symptoms at some point—perhaps when you forgot to take a scheduled dose of medication. Opioid withdrawal is highly unpleasant. If you experience withdrawal symptoms, this does not meant that you cannot get off opioids...
"It doesn't matter how old you are or if you're in a wealthy country or a poorer one or if you've had it before—you can get it again," says Sarah M. Bartsch. "And it is really unpleasant. But if we don't focus on norovirus and teach people how to prevent it, little headway will be made to combat it."
It is a popular belief that women who live together synchronise their menstrual cycles, and that it’s mediated by their pheromones – the airborne molecules that enable members of the same species to communicate non-verbally.
Ever since I was a child, I chased the sun. I was ecstatic in the summer and miserable in the winter. My parents would have to chase after me to wear a hat and long sleeves because I wouldn’t think about sunburns or skin cancer at all, all I could think about was JOY.
Many of us have experienced intense cravings for dishes our moms or dads used to cook. Indeed, it would make sense that our parents' cooking forever shapes our food preferences.

Being overweight and not getting enough exercise are considered major contributors to insulin resistance and, ultimately, type 2 diabetes. But new research suggests specific imbalances in gut bacteria play a role, too
Our facial appearance influences how we feel about ourselves – and other people’s faces influence who we choose to approach or avoid and who we’d like to form romantic relationships with.
Child abuse and neglect are, sadly, more common than you might think. According to a 2011 study in JAMA Pediatrics, more than five million U.S. children experienced confirmed cases of maltreatment between 2004 and 2011. The effects of abuse can linger beyond childhood – and migraine headaches might be one of them.

Regular exercise in middle age is the best lifestyle change a person can make to prevent cognitive decline in their later years, a 20-year study finds.
A few years ago I proudly lost almost 15% of my weight. However last week I stared with disbelief at my scale as I realised all my efforts were in vain and I had regained all of the previously lost weight.
For thousands of years humans have defended themselves from harm by others. But many have proceeded to regularly harm themselves. They have actively searched for substances to ingest, inhale, inject and apply which may give them some immediate relief but damage or destroy their lives over time.
According to the World Health Organization (WHO), more women are affected by depression than men. This pattern is seen in countries around the world, including the United States.
In this modern age, we tend to run from the sun due to what I believe to be understandable but overblown concerns about skin cancer. Since the time of the Greeks, heliotherapy (sun therapy) has been a valuable way to heal the body and balance the mind.

Since the 1980s biologists have used genetic engineering to express novel traits in crop plants. Over the last 20 years, these crops have been grown on more than one billion acres in the United States and globally. Despite their rapid adoption by farmers, genetically engineered (GE) crops remain controversial among many consumers, who have sometimes found it hard to obtain accurate information.
A revolution in how we think about preventing cavities in children is upon us. Evidence shows that cavity formation has less to do with genetics, candy habits or poor brushing, and more to do with the types of snack foods we give children. Counter-intuitively, dark chocolate is better for teeth than pretzels or crackers.
I find it sad that people have to keep discovering wisdom through their own tragedies. I am saying this in the hope that you will take the time to read on, learn from the wisdom of others, and not require a disaster to become your teacher.
Have you ever wondered how freshly baked bread gets its a golden brown crust and why it smells so good? Or how nondescript green berries turn into beautiful brown coffee beans with a rich alluring aroma?

The story of that day – the squares of infantry repulsing cavalry charges, the Imperial Guard retreating under murderous musket fire delivered by a red line of soliders, the just-in-time arrival of Field Marshal Blücher’s Prussian army – is one of excitement, horror and heroism.
We know so much about the genes that cause disease, so why are we not approaching an age of Star-Trek-like medicine in which a doctor can wave a handheld device over a patient, claim to have sequenced the genes of the offending pathogen, then move rapidly to a cure?
The near panic caused by the rapid spread of the Zika virus has brought new urgency to the question of how best to control mosquitoes that transmit human diseases. Aedes aegypti mosquitoes bite people across the globe, spreading three viral diseases: dengue, chikungunya and Zika.
Last week, the National Obesity Forum caused a furore by claiming that eating fat, including saturated fat, will help cut rates of obesity and type 2 diabetes. Public Health England hit back, calling NOF’s advice “irresponsible”.
Marisa Fisher's research suggests people with Williams syndrome can learn to say no to strangers, refuting past studies that indicated sociability may be hard-wired in individuals with Williams syndrome.
Alcohol: why do we drink it? People have been consuming alcohol for at least 10,000 years. And when drinking water was rather risky, alcohol seemed a much safer bet. Amaldus of Villanova, a 14th-century monk, even wrote that alcohol “prolongs life, clears away ill humors, revives the heart and maintains youth”.
"As doctors, we throw things like antihistamines, ointments, and lotions at patients who suffer chronic itching, but if there is something profoundly abnormal about the immune system—as it appears there is—then we can't solve the itching until we address those underlying causes," says Brian S. Kim.
In the past week you’ve probably eaten crops that wouldn’t exist in nature, or that have evolved extra genes to reach freakish sizes. You’ve probably eaten “cloned” food and you may have even eaten plants whose ancestors were once deliberately blasted with radiation. And you could have bought all this without leaving the “organic” section of your local supermarket.
Despite massive government, medical and individual efforts to win the war on obesity, 71 percent of Americans are overweight. The average adult is 24 pounds heavier today than in 1960. Our growing girth adds some US$200 billion per year to our health care expenditure, amounting to a severe health crisis.
"Conflict happens in every marriage, but people deal with it in different ways. Some of us explode with anger; some of us shut down," says Claudia Haase. "Our study shows that these different emotional behaviors can predict the development of different health problems in the long run."
