The same process that led to the evolution of complex life may be happening all over again in insects, according to a new study in the journal Cell. About 900 million years ago, the Earth was covered in vast oceans containing giant mats of bacteria. Single-celled organisms with little more than a nucleus topped the food chain. At some point, they engulfed photosynthetic organisms called cyanobacteria , incorporating them into their cells and forming the world's first proto-plants and algae, according to recent research in the journal Proceedings of the National Academy of Science.

NEW YORK - There are bugs in the trees. There are bugs on the shrubs, on screen doors, on barbecue grills, on front steps. There are shells of bugs on the ground, crunchy as tempura, and bug bodies clinging onto leaves, their dead orange eyes still beady. There is a large live bug on John Kempf's collar, and a dead one in his 6-year-old son Aren's hand. Neither seems to mind. "I love them; it's nature," said Kempf, a Staten Island resident who recently collected 300 bugs in a cooler to bring to his yard, in the hope they would multiply.

The school health clerk took a comb and pointed to the near-microscopic bugs crawling up and down my daughters' scalps. I cringed. Then she checked my head for the pesky parasites. I held my breath. We had lice. Lots and lots of lice. My youngest daughter scratched her head and started crying. Embarrassed, we headed home. And that began the frustrating, icky, unending, exhausting, humiliating, disgusting battle against the bugs. Parents across the nation are terrified of lice - not because they cause disease, but because even one minuscule egg has the power to keep children out of school and their mothers and fathers out of the office.

As the East Coast of the United States braces for the deafening invasion of the 17-year cicada, a motley collection of predators -- including some humans -- are licking their chops in anticipation of an immense insect feast. Billions of cicada nymphs will soon spring from their hiding place below ground and eventually fly to the treetops for a courting, mating and egg-laying ritual of biblical proportions. The massive emergence, which University of Maryland entomology professor Michael Raupp likened to a " huge tsunami ," will roll from North Carolina to New York.

Humans could learn a thing or two from lowly sand termites about managing the Earth's natural resources. Mysterious African "fairy circles," up to 55 yards across, are created by these creatures, according to a study published in Friday's edition of the journal Science. Fairy circles are formations that appear along a 1,200-mile belt that stretches along the southwestern edge of Africa, from the middle of Angola to Namibia to the northern edge...

A study published Wednesday on a dengue fever outbreak in Key West, Fla., has local health officials buzzing. The paper, which was published by the Centers for Disease Control and Prevention and appeared in their journal, Emerging Infectious Diseases , confirmed that the mosquito-borne illness had indeed returned to the U.S. mainland after an absence of decades. However, Monroe County Health Department Administrator Bob Eadie said the report may leave people with the mistaken impression that the dengue risk remains.
