Why Hard Physical Work Is Not the Same as Exercise for Brain Health
A sweeping new meta-analysis covering more than 4.2 million people has uncovered a striking paradox: while leisure-time physical activity reduces dementia risk by roughly 24%,...
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?
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.
Have you ever been listening to a great piece of music and felt a chill run up your spine? Or goosebumps tickle your arms and shoulders?
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.
More than half of jobs are found with the help of a social tie, whether a friend, relative or distant acquaintance. For example, a friend may tell you about a job opening at her firm or a parent may offer you an internship at his company.
"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."
The researchers examined the productivity differences between two groups of call center employees over the course of six months and found that those with stand-capable workstations—those in which the worker could raise or lower the desk to stand or sit as they wished throughout the day—were about 46 percent more productive than those with regular desks and chairs.
"Our theory explains specifically why primates developed superintelligence but dinosaurs—who faced many of the same environmental pressures and had more time to do so—did not. Dinosaurs matured in eggs, so there was no linking between intelligence and infant immaturity at birth," says Celeste Kidd.
“I have something to say. I want to share it with you.” By tapping a few keys in a specific sequence, I have made a code emerge on the screen. When you see these words, the language area of your brain (usually the left side) converts the sequence into meaning. If I have selected well, this meaning will match the message I wanted to convey.
Traditionally, someone who suffered from hypertension – or high blood pressure – would only receive treatment when his or her blood pressure was measured and the reading was found be higher than normal. But this meant that the condition was often picked up only when the person had a stroke or a heart attack – and in many instances this was too late.
It only takes a single fly to alight on your picnic lunch to make you uneasy about what germs may have landed with it. But what harm can come from a fly landing on your food? Should you throw it away?
Consuming too much energy – whether from fat or carbohydrates, including sugar – will make you gain weight. If left unchecked, this excess weight increases your risk of lifestyle-related diseases such as diabetes, heart disease and some cancers.
"It's a little bit like some kind of Halloween stuff happening," says Omer Inan. "You're listening to your bones rubbing on each other, or maybe cartilage."

Music and movies are umbilically entwined in the films of Martin Scorsese. It’s almost impossible to think of his cinema without the propulsive accompaniment of a track by The Rolling Stones, Muddy Waters, Eric Clapton, a Neapolitan street singer or any number of other smaller and even obscure doo-wop, Latino, Brill Building and r “n” b wonders of the 1950s, 60s and early 70s.
Have you ever wondered why you have so many different types of flour in your pantry? You might have cornflour and arrowroot, self-raising, and plain flour. And if you like to bake bread, possibly strong bakers’ flour.

The study shows that blue-enriched light exposure acutely altered metabolic function in both the morning and the evening compared to dim light
"A shift of attention is needed from disease-focused management, such as medications for hypertension or high cholesterol, to overall well-being across many areas," says William Dale.
