Anyway, it turns out they're not just in Napoleon Dynamite! There's a real liger in Russia!

Its presence is required to explain the extra gravitational force that is observed to hold regular galaxies together and that also binds large clusters of galaxies. These galaxies are rotatating too quickly to be explained by the observed amount of gas. Something else must serve as gravitational glue.

Dark matter makes up about 23 percent of the universe's mass-energy budget. Normal matter, the stuff of stars, planets and people, contributes just 4 percent -- similar to the grain of sand fact.

You can learn a lot by looking at a car's VIN -- where it was made, manufacturer, body style, engine type, assembly plant...

And using CarFax, you can lookup the vehicle's detailed history (flooded? accidents? rental car? rolled over?) -- all just by entering the VIN

It was renamed Pepsi-Cola because of its pepsin and kola nut content.

The US Treasury Department appropriates the money and returns it to circulation.

She survived.

An attosecond is 1 x 10^-18 seconds. To imagine how long this is, if 100 attoseconds is stretched so that it lasts one second, one second would last 300 million years on the same scale. But by using lasers, we may be able to make new clocks that are accurate to one second over a billion years (more accurate than atomic clocks).

Turns out there is no recorded date of Christ's birth. In AD 320, Pope Julius I chose December 25 in an effort to absorb the customs of the pagan festival Saturnalia, a holiday marking the winter solstice on Dec 22nd every year.

After hanging up the skates,
Tonya must have been in dire straights
Because now she's had one too many lunches
and makes her money throwing punches
at a woman slash man.
Who would have thought when her career began?

It is has been reported by different studies that 100,000 to 500,000 newborns are accidentally switched at birth every year -- and given to wrong parents! According to the 1998 Edition of the Tanderberg Report, (an annual medical study by sociologist Dr. Morton Tanderberg, and as reported by Ann Victoria in Weekly World News, p. 22, on 9-8-98), 500,000 or 1 out of every 8 babies born in American hospitals is sent home with the wrong parents.

In many cases, these oversights are caught and corrected within a few days and the babies are returned to their mothers. But on the other end of the scale, Dr. Tanderberg says that in some overcrowded facilities, particularly in large metropolitan areas like New York, Los Angeles and Chicago, the number of switched babies could be considerably higher -- possibly as high as 3 out of 8.

Thus, a work out on a warm, humid day can make you much more susceptible to heat stroke than a hot, dry one -- in other words, it just might be true that "It's not the heat but the humidity that will kill you."

As surprising as it is, on a 100-foot course, you soak up more than twice the rain by running instead of walking. By walking, it's really only the top of your head and your shoulders that get wet. When you run, you get the whole front face of your body wet as well.

Do onions bother you? No wonder! The reason that onions cause people to tear up is that onion cells contain a sulfur-containing chemical compound. When your knife slices through that, it triggers a series of chemical reactions. When the new molecules react with the moisture in your eyes, sulfuric acid -- the most widely used of all chemicals and a major component of battery acid and acid rain-- is formed.

But good ol' Texas is keeping its young ladies safe from such worries. The town of Nacogdoches, has a strict onions curfew for "young women." Under no circumstances are they allowed to have any raw onions after 6 p.m.

The longest scientific word in the English language is "pneumonoultramicroscopicsilivolcanoconiosis."

So what is Victoria's secret? Turns out no one knows!

Tiny ultra-sensitive ears can detect the movement of prey within a quarter of a mile!

Hypersensitive nostrils can detects a single drop of blood in the water up to 50 yards away. The jaws of a great white can exert 42,600 pounds per square inch of pressure - 24 times the power of a jackhammer.

Great whites have 50 triangle-shaped teeth at any given time. The narrow bottom ones grab and hold prey while the top row cuts the flesh. As front teeth are broken or lost, they are replaced by the new ones from multiple rows of reserves.

The average human loses between 3 and 6 liters of water on a typical day. One to two liters rushes out as urine, and another one-tenth liter in defecation. Water lost as vapor when you breathe could fill around 1 to 2 liter water bottles a day-even more in arid locations. Sweat fills up another 1 to 2 liters on an average day, but that amount can reach 1 to 2 liters per hour in an intense workout.

But if you're dehydrated, that super gulp won't give you the quick fix you dream of. The body can only absorb about 1 quart per hour...

This means that beachfront property is so expensive because there is only 5.54 centimeters of coastline per person in the world.

The phrase was confined to Illinois high-school ball until 1982, when CBS broadcaster (and ex-Chicago Daily News sportswriter) Brent Musburger used it during his network's NCAA tournament coverage.

Way to go Carolina -- 2005 National Champions! Coincidence?

The answer is a chemical compound called Capsaicin (see also a January fact), which is found in the inside wall of the pepper and in its white lining. Capsaicin is odorless and tasteless, except for the hot, tangy sensation it yields. The true flavor of a pepper comes from its outer walls.

According to research at McMaster University in Canada, people trust people who look like them. In addition, the participants of this experiment described the similar faces as sexually unattractive.

"Almost" is the longest word in the English language with all the letters in alphabetical order.
