We all thought we knew why chameleons change color, but most of us were probably wrong. Chameleons on today’s Moment of Science.
Over the past few decades, the earthworm population has severely decreased. Since the New Zealand flatworm accidentally made its way to the British Isles in 1963, it has wreaked havoc on some of the land, devouring fields of earthworms.
As you land on top of her you realize too late the mistake you have made. You do whatever it is that bees do when they are terrified. This is no female bee, no possible mate.
Botox is the marketing name given to a neurotoxin called botulinum toxin A. This toxin comes from the bacterium that produces the poisons responsible for causing botulism.
But the farther away the gun is, the wider the beam gets spread so that only a small fraction of the total light power can go into anyone’s eye.
Once the electric circuit is completed, an electric current begins to run though a cylindrical coil of wire, or solenoid. The electric current creates an electromagnetic field around the solenoid.
Eating snow to obtain water is metabolically expensive–it would take too much energy to melt down enough snow. Consequently, polar bears have evolved so that they don’t need to drink free water.
While the tombs of ancient Egyptian royalty do indeed bear curses calling down death and destruction on all who enter, tombs all over the world hold hidden perils for explorers, like Lord Carnarvon, who discovered King Tut’s tomb only to die suddenly shortly afterward.
Do fish actually have a working memory? Recent experiments show that fish can in fact remember things for several days.
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.
This means that instead of staying in one place, the cancer cells migrate from their original site to other parts of the body.
When a beaver chews on a cottonwood, the tree does release these noxious chemicals as usual, but the bitter chemicals released into the tree’s new leaves actually attract a certain leaf-eating beetle.
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.
By temporarily altering the shape of the pinnas with plastic molds, researchers in the Netherlands found that indeed, people with new pinnas had a hard time locating sound sources.
However, mosquitoes, contrary to poplar belief, are not bugs. Another factor that comes into play is the fact that baby true bugs look like small wingless versions of adult true bugs.
The song says that Bonnie lies over the ocean, but it also says that she lies over the sea. Based on these lyrics, where is Bonnie? In the song, the words “ocean” and “sea” are used interchangeably to mean any large body of salty water.
This means that the ice cover contains microorganisms that date back thousands of years; recently scientists found microorganisms that froze way back when Rome was founded.
Finally, Bottoms notes that her surveys found zero instances of Satanic cults abusing children. There was a time back in the nineties when the idea that Satanic cults existed and were abusing children was widespread, but the data don’t back this up–though the actual facts are even more sobering.
Having trouble keeping your indoor plants alive? Well you may not have the right type of plant that is suitable for indoor life.

Ever wonder if you can actually turn blue while holding your breath? Find out 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!
Vampire bats may seem like a blood problem you may have to deal with. However, you should be worrying about having a stroke!
If you look at the horizon at sunset–exactly as the last sliver of sun disappears–you might see a flash of brilliant green blaze across the sky.
The large ones we see when a bird stretches its wings are “flight feathers,” but they also have fluffy ones called “down feathers.”
While in the tube, the worm’s tail end might be immersed in temperatures as hot as 178 degrees Fahrenheit, while its head rests in cooler water, as moderate as 72 degrees Fahrenheit.
In this Moment of Science, we explain how and why the collapse of the Twin Towers occurred.
