Featured Article: Boudica

Boudica (also Boudicca, Boadicea, Buduica, Bonduca) (d. 60 - 61 C.E.) is a heroine of the Brythonic Celtic Iceni people of Norfolk in Eastern Roman Britain. Upon the death of her husband Prasutagus (ca. 60 C.E.), the Romans first annexed his kingdom and then brutally humiliated Boudica and her daughters, spurring her leadership. She led a major uprising of the Celtic tribes against the occupying forces of the Roman Empire. Boudica was ultimately defeated at the Battle of Watling Street by the heavily outnumbered forces of Roman provincial governor Gaius Suetonius Paulinus.

The chronicles of these events, as recorded by the historians Tacitus, and Dio Cassius were rediscovered during the Renaissance. This discovery led to a resurgence of Boudica's legendary fame during the Victorian era, when Queen Victoria was portrayed as her "namesake." Boudica has since remained an important cultural symbol in the United Kingdom.

An enzyme is a biological catalyst that regulates the rate of a chemical reaction in a living organism. Most enzymes are proteins, though certain nucleic acids, called ribozymes, are also capable of catalytic activity.

Enzymes are essential to sustain life because most chemical reactions in biological cells, such as the digestion of food, would occur too slowly or would lead to different products without the activity of enzymes. Most inherited human diseases result from a genetic mutation, overproduction, or deficiency of a single critical enzyme. For example, lactose intolerance, the inability to digest significant amounts of lactose, which is the major sugar found in milk, is caused by a shortage of the enzyme lactase.
