A Moment of Science
The North Pacific High is part of a relatively stable high pressure system in the Pacific Ocean that influences the weather.
We generally say the heart is on the left side of the chest because about two-thirds of its mass is to the left of the sternum.
Before giving an answer, let's think for a second about the kind of thing we can learn even from so commonplace an event.
Hard exercise can raise your body temperature as much as four or five degrees.
There are thirty-eight cat species in the world, but none of them command the respect and awe of the tiger.
Scientists studying rodent species have found that urine odor is an important cue.
Skeletal muscles are attached to bone structures and cannot stay long in a flexed position without depleting their energy reserves.
Barnacle geese leave Europe in spring and fly north to breed on rocky Arctic islands.
As a meteor passes into Earth's atmosphere it experiences tremendous air resistance on its front end, but very little on its back end.
When a train enters a tunnel, it compresses the air in front of it like a piston. Air in a tunnel can't be simply pushed aside--the tunnel walls are in the way.
The most famous tunnel is the thirty mile "Chunnel" between England and France. The Chunnel is actually two separate tunnels, connected by cross passages.
In evolutionary terms, a "successful" organism is one that passes on its genes -- not necessarily one that lives a long life.
Isolated from their mainland relatives, these house mice evolved over time into a distinct species, larger and shaped differently from their ancestors.
Learn about alternative energy sources other than solar and wind power.
There could be a molecular solution to treating cholera---a disease that affects millions of people around the world.
Fungus may not sound too appetizing, but the white fluffy growths are much more nutritious than leaves. We use a similar process with cows.
Did you know that tracking weather in the Pacific gives meteorologists advanced warnings of coming tornadoes here on the mainland?
Chloroplasts should not be able to work once they are removed from algal cells because those cells contain proteins that control their operation.
Astronomers have proposed two theories to explain the mysterious origin of blue stragglers.
