In most species of social insects, such as wasps, bees, and ants, the females rule. The females are the workers.
In this Moment of Science we discuss the importance of whole grains, as well as what they are in the first place.
Depo-provera is the brand name of a method of birth control that consists mostly of a hormone much like progesterone, a hormone that works with estrogen to regulate the menstrual cycle.
Surprisingly, snow makes good insulation. In physics, an insulator is a material that does not conduct heat very well, like an oven mitt.
The natural fragrance of flowers counts among the simpler pleasures in life.The delicate aroma of a rose in bloom is something that does not require explanation; we enjoy it simply and intuitively.
Ironically, the general covering of our bodies in hair — what we call “fur” on other animals — is at the root of our problem with acne.
All you need for this trick is a twenty-five-cent piece and a small postage stamp. Put the stamp on the desk and hold the quarter horizontally about half an inch above the stamp. Now blow hard down onto the quarter.Now blow hard down onto the quarter.
You may have heard that drinking a glass of wine a day can help prevent heart disease. Not only that, but there’s also been recent research suggesting that wine may also prevent dementia and Alzheimer’s disease.
If you live in the middle latitudes of the northern hemisphere, the moss will grow thicker on the north side. It may sound like an urban legend, but it’s quite real. And the reason is simple: there’s more sun on one side.
The sweet taste of a substance has to do with how well the molecules that make up the substance chemically bind with the sweet taste receptors in our mouth. The amount of energy released when we metabolize this substance, is measured in calories.
Is the force of gravity increasing? Find out on this Moment of Science.
We hear a lot about insect pests, but have you ever heard about the zebra mussel and what it can do to power plants? Find out on today's Moment of Science.
Their descendants were even more vain, so in 16th century Venice mirror makers discovered the technique of backing a piece of glass with a reflecting metal composed of tin and mercury, producing a much clearer reflection.
Read on to learn about the possibility that infants are interested in the same things as their parents.
For nonlinguistic activities that involve the mouth people tend to open their mouths more symmetrically or on the left side.
Cognitive neuroscientists at Washington University in St. Louis have investigated the relationship between mood and cognitive performance by showing subjects ten-minute clips from both classic horror films and prime-time television comedies.
Any motion takes energy to perform. And little motions like rearranging things on your desk or stretching your back, if you do them all the time, start to add up.
The third kingdom contains all organisms whose cells have a nucleus, including plants, animals, algae, and even fungi. So evolutionarily speaking, humans and fungi are cousins.
Ordinary ocean waves are caused by the action of wind, like ripples on a wind-blown pond. Even the impressive surf of the Pacific got its start as wind blowing across the open water. The height of such waves depends on how fast the wind is blowing, and how much open water the wind travels across.
It turns out that one of nature’s most foolproof navigators is none other than the Caribbean spiny lobster. Various attempts to disorient lobsters–which involve goofy things such as taking them away from their homes while they’re wearing eye coverings–never succeed.
The North Pacific High is part of a relatively stable high pressure system in the Pacific Ocean that influences the weather from northern Mexico, to the far-west and Southwest United States. In a high pressure system, air from up above tends to move downward to ground level.
If you were able to shrink and infiltrate a termite colony you’d notice four distinct groups: workers, soldiers, immature individuals, and reproductives. The workers are the Cinderellas of the termite world; blind, sterile, and wingless, they tend the eggs, feed the soldiers and young termites, and maintain the nest.
Some research has shown that people snore less in space. Today on A Moment of Science, we’re going to discuss what ramifications this has for us down-to-earth snorers. Scientists recently monitored the sleep of five astronauts on the International Space Station, and discovered that weightlessness actually improves sleep. One common sleeping disorder, known as sleep [...]
Learn about the love-relationship between salmon and riparian vegetation on this Moment of Science.
If you are grinding your teeth you could be wearing the enamel down, as well as causing damage to your jaw. When we’re asleep, we’re capable of grinding our teeth six times as hard as we might in the day. That kind of pressure can do a lot of damage.
By the time the average passenger car tire ends up at the scrap yard, it weighs six pounds less than when it was new. Multiply six pounds by the number of tires scrapped each year in the U.S., and we’re talking over three-quarters of million tons of rubber that perform a disappearing act every year!
No matter the species, mating rituals are pretty weird. Take the praying mantis. After an intimate tryst, the female mantis bites its partner’s head off. But when it comes to sexual hijinks, nothing beats the garden snail. During sex, garden snails often pierce each other with miniature darts. Any way you slice it, garden snail [...]
“Bloodshot” is precisely the right term to describe what happens when something irritates the eyes.
Two studies suggest that those individuals most prone to violent behavior are narcissists. In Greek mythology, we know Narcissus as the man who fell in love with his own reflection in the waters of a spring, and whose excessive self-love killed him.
