The Buckeye Tool Expo in Dalton, Ohio, is held in a massive hall filled with bearded men in black hats and women in white bonnets. A few horses and buggies are tied up outside.
The Amish have chosen to forgo many of the delights of the modern world, but they still need to drill, sand and cut wood. This trade expo shows off all the loopholes that let the Amish get their hands on power tools.

Figurines representing the main candidates of the upcoming Italian general election are on display in a shop in Naples. Seen (clockwise from left) are magistrate Antonio Ingroia, former Prime Minister Silvio Berlusconi, Oscar Giannino, outgoing Prime Minister Mario Monti, Grillo and the Democratic Party's Pier Luigi Bersani.
Italy's election campaign has been dominated by an upstart comedian-turned-politician whose Five Star Movement is soaring in the polls. The movement is not expected to win in the weekend vote, but its strong presence in Parliament could be destabilizing and reignite the eurozone crisis.
Beppe Grillo is a standup comedian and the country's most popular blogger; 63 years old, with a mane of grey curly hair, he's hyperactive and foul-mouthed. His last name means "cricket," and he's the most charismatic politician in Italy today.

<strong>Visible spectrum.</strong> Certain bright colors and petal shapes attract certain pollinators.
Flowers are nature's ad men. They'll do anything to attract the attention of the pollinators that help them reproduce. That means spending precious energy on bright pigments, enticing fragrances and dazzling patterns.
Now, scientists have found another element that contributes to flowers' brand: their distinct electric field.
Anne Leonard, who studies bees at the University of Nevada, says our understanding of pollinator-flower communication has been expanding for decades.
