Psychologists have a pretty good idea of what typically makes a human happy. Dancing delights us. Being in nature brings us joy. And, for most people, frequent contact with good friends makes us feel content.
That is, unless you’re really, really smart.
Hard-boiled eggs are one of those kitchen staples I always have in the fridge. They’re great for out-of-hand snacking, they instantly add a protein boost to salads, they form the basis of a super-speedy breakfast, and — with just a little extra effort — they become deviled eggs, the perfect cocktail snack.
There are few discomforts quite as annoying as the “water balloon inside your belly” feeling known as bloating. But luckily there are some tricks you can try to help limit the swelling. We enlisted a few experts—a heralded doctor who specializes in digestion and inflammation, a clean-eating expert, and a hormone specialist—to share their tips for beating bloat, both in the moment and before it happens.
On June 4, 2013, the city of Huntsville, Alabama was enjoying a gorgeous day. Blue skies, mild temperatures. Just what the forecasters had predicted.
But in the post-lunch hours, meteorologists started picking up what seemed to be a rogue thunderstorm on the weather radar. The “blob,” as they referred to it, mushroomed on the radar screen. By 4 PM, it covered the entire city of Huntsville. Strangely, however, the actual view out of peoples’ windows remained a calm azure.
Food marketers know that if they call their product a superfood, it’s sure to sell. Take quinoa, for example. In the early aughts, when the ancient grain first became trendy, quinoa prices tripled in the span of five years. (Many Bolivians, who had relied on it as a food staple for centuries, were soon priced out of the market.) The moral here: it’s important to question anything knighted with the superlative.
The avocado is a fruit of a different time. The plant hit its evolutionary prime during the beginning of the Cenozoic era when megafauna, including mammoths, horses, gomphotheres and giant ground sloths (some of them weighing more than a UPS truck) roamed across North America, from Oregon to the panhandle of Florida. The fruit attracted these very large animals (megafauna by definition weigh at least 100 pounds) that would then eat it whole, travel far distances and defecate, leaving the seed to grow in a new place. That’s the goal of all botanical fruits, really. Survival and growth via seed dispersal.
Someday, solar panels may be light and cheap enough that they could be hung on a clothesline, thanks to a synthetic mineral called perovskite. Physicist Sam Stranks explains the science and the challenges that stand in its way.
The peacock’s dazzling tail feathers do not exist for them to carry out everyday activities such as eating or sleeping, but because their colourfulness is attractive to peahens: the more brilliant the feathers, the greater the chance the peacock has of finding a sexual partner. Tail feathers, to peahens, can be powerfully attractive. Scientists have long been interested in unravelling the subconscious processes that influence partner choice, since heritable characteristics that are favoured in sexual partners will tend to increase in frequency in subsequent generations. That’s why the peacock’s tail feathers are so radiant: over many generations, more beautiful tail feathers have been selected. This means that partner preferences tell us something about the evolutionary pressures that shape a species – including us. So what do we find attractive in each other, and why?
Aimee Hartley, like most people, thought she knew how to breathe – she had, after all, been doing it all her life. She had also given it plenty of thought, having trained as a yoga teacher. But then she took a lesson with a breathing coach, who told her where she was going wrong. He pointed out she wasn’t taking the air into her lower lungs but was, she says, an “upper chest breather. He then taught me this conscious breathing and I felt my lower belly open, and I felt myself breathing a lot better after just one session. So I then became fascinated by how we breathe.”
Pauline Dakin’s childhood in Canada in the 1970s was full of secrets, disruption and unpleasant surprises. She wasn’t allowed to talk about her family life with anyone – and it wasn’t until she was 23 that she was told why.
