Upper and lower case letters are named 'upper' and 'lower' because in the time when all original print had to be set in individual letters, the 'upper case' letters were stored in the case on top of the case that stored the smaller, 'lower case' letters.
The nematode Caenorhabditis elegans ages the equivalent of five human years for every day they live, so they usually die after about fourteen days. When stressed, though, the worm goes into a comatose state that can last for two or more months. The human equivalent would be to sleep for about two hundred years.
Catnip, or Nepeta cataria, is an herb with nepetalactone in it. Many think that when cats inhale nepetalactone, it affects hormones that arouse ual feelings, or at least alter their brain functioning to make them feel "high." Catnip was originally made, using nepetalactone as a natural bug repellant, but roaming cats would rip up the plants before they could be put to their intended task.
Jellyfish like salt water. A rainy season often reduces the jellyfish population by putting more fresh water into normally salty waters where they live.
Many sharks lay eggs, but hammerheads give birth to live babies that look like very small duplicates of their parents. Young hammerheads are usually born headfirst, with the tip of their hammer-shaped head folded backward to make them more streamlined for birth.
Sharks and rays are the only animals known to man that don't get cancer. Scientists believe this has something to do with the fact that they don't have bones, but cartilage.

The wick of a trick candle has small amounts of magnesium in them. When you light the candle, you are also lighting the magnesium. When someone tries to blow out the flame, the magnesium inside the wick continues to burn and, in just a split second (or two or three), relights the wick.
According to security equipment specialists, security systems that utilize motion detectors won't function properly if walls and floors are too hot. When an infrared beam is used in a motion detector, it will pick up a person's body temperature of 98.6 degrees compared to the cooler walls and floor.
If the room is too hot, the motion detector won't register a change in the radiated heat of that person's body when it enters the room and breaks the infrared beam. Your home's safety might be compromised if you turn your air conditioning off or set the thermostat too high while on summer vacation.
