Come summertime, some of us here at Shots are reminded, as we lounge on decks and venture into overgrown gardens, that we are irresistible to mosquitoes. As we gripe about our itchy, pocked limbs, we can't help but wonder just why they unfailingly devour us and pass over our friends and loved ones. And when it comes to repellent, it's hard to tell just what works best.

Last year, scientists got the chance to solve a medical mystery — well, at least half of it. This week the final puzzle pieces fell into place, as investigators tracked the newly identified virus to an eight-legged bug.
The mystery actually began with two Missouri farmers who came down with a strange illness in 2009. They had high fevers, diarrhea and nausea. Their platelet counts dropped dramatically, though they didn't experience any abnormal bleeding.
Homicide remains a leading cause of death for young people, even as rates drop. In Chicago, a teenage boy grieves next to a memorial where Ashley Hardmon, 19, was shot and killed on July 2. Gunmen fired while she was chatting with friends.

Homicide rates among teenagers and young adults have dropped to the lowest level in 30 years, according to the Centers for Disease Control and Prevention.
That's good news, but it still means about 4,800 young people under age 25 were murdered in 2010.
Teenagers and young adults remain more likely to be killed than older adults, and homicide is a leading cause of death in the young, behind motor vehicle accidents.
