Summertime ushers in a bevy of fresh fruit enjoy and in no time, a bevy of fruit flies. With a keen sense of smell, fruit flies hone in on a juicy cantaloupe or overripe bananas tossed on the compost pile. Although they're a pest in the kitchen, fruit flies have been a focus of research for over 100 years, and today there are hundreds of labs dedicated exclusively to studying them.
One of my little psychological tics revolves around those little stickers on apples and oranges. For whatever reason they weird me out - I can pull them off and wash the fruit a thousand times and still I'll think of the trace amounts of invisible sticker goo I'm probably imbibing along with nature's candy.
