Rather than artificially bypassing sleepiness—our natural “safety device”—with sweets, caffeine, or other stimulants, we should heed it and simply get some sleep. Most adults need seven to eight hours of sleep every night to look, feel, and perform their best. Young people need more. Sleep-deprived teens are more prone to have psychological troubles…

10 ways to keep your Online Data Safe

In today’s digital world, banking, money transfers, and payments—as well as medical, corporate, and government records—are secured by means of complex encryptions. The ciphertext, in turn, is read by those who have the necessary decryption key to restore the data to its original form. Whereas a metal key usually has a set of grooves, a digital key is a string of zeros and ones in various combinations. Longer keys have more combinations and are thus harder to crack. An eight-bit key, for example, has 256 possible combinations, or permutations, whereas a 56-bit…

Earth’s magnetic Protection

The Earth’s magnetic field originates deep inside the planet and stretches far into space, where it forms an invisible shield called the magnetosphere. This shield protects us from the full force of cosmic radiation and from dangers emanating from the sun. The latter include the solar wind, which is a steady stream of energetic particles; solar flares, which release in minutes as much energy as billions of hydrogen bombs; and coronal mass ejections (CMEs), which blast billions of tons of matter from the sun’s corona into space. Both solar flares and CMEs trigger…

How Do Bees Make Honey

Foraging bees collect nectar from flowers, sucking it up with their tubelike tongues. They carry it back to the hive in one of their stomachs. The nectar is transferred to other bees who “chew” it for about half an hour, mixing it with enzymes from glands in their mouth. Then they place it in hexagonal cells made of beeswax and fan it with their wings to dehydrate it. After the water content is reduced to less than 18 percent, the cells are capped with a thin layer of wax. Capped honey can…
