The males of the Cervidae (deer) family, such as elk, moose, deer, and caribou, grow antlers on their heads. Caribou are the only species in which the females also have antlers. Antlers are branched structures made of bone. Most antlered animals shed them annually in the fall or winter and then grow new antlers in the spring. Horns, unlike antlers, don't fall off but continue to grow throughout the animal's life. Further, horns aren't branched, nor are they made entirely of bone. Horns contain a bony core that is covered with a sheath of keratin, similar to the material of fingernails. Horned animals, which include sheep, cows, bison, and goats, are in the Bovidae family. In many Bovidaespecies, both females and males have horns.

Mexico has one of the highest rates of soda consumption in the world, a fact of significant concern to those who promote public health. Several years ago, the Mexican government decided to address this issue. The question they faced was how to encourage people to drink less soda. The answer they settled on was to impose a tax on soft drinks. This appears to have helped, as soda consumption in Mexico has gone down since the introduction of the tax.

Bicycles have evolved over many years. In 1818, a heavy two-wheeled device called a "velocipede" was patented in Paris. The rider controlled the direction with a steering wheel and moved it forward by pushing his feet on the ground. It caught on quickly, and many people worked to refine its design. In 1863, pedals were added. A few years later, a new, lighter bike was developed that used a very large front wheel and a small rear wheel. Called the "Ariel," it became popular but was quite accident-prone. Over the next decade, "safety" bicycles were produced, incorporating welcome improvements such as air-filled rubber tires, brakes, and gears. By 1899, about a million bicycles were in use.

The flying beetle known as the firefly or lightning bug is named for its most noticeable feature: its nighttime bioluminescence, or glow. The firefly's light-producing organ contains calcium, the pigment luciferin, the light-producing enzyme luciferase, and the chemical adenosine triphosphate (ATP). When oxygen is added to this mix, it creates light, and the insect glows. Scientists don't fully understand how the firefly makes its light blink, but one theory is that the firefly turns the light on and off by controlling the input of oxygen into the light-producing organ.

If you think an alligator is the same as a crocodile, think again. It's true that the two types of animals are related, and they look similar. Yet although both are large reptiles with scales and webbed toes, and both live near water in tropical or semitropical areas, there are important differences between them. An alligator lives only in fresh water, while a crocodile can live in brackish, or somewhat salty, water. An alligator's snout is also wider and "U"-shaped, whereas a crocodile's is longer and "V"-shaped. Finally, their behavior differs: it's generally agreed that crocodiles are more aggressive than alligators.
