"Twilight's" creator Stephenie Meyer clearly has a few obsessions she can't quite shake: interspecies romance, love triangles and color-coded eyes - red-rimmed if vampires are involved, silver for the sci-fi aliens of "The Host. " All those elements appear in writer-director Andrew Niccol's adaptation of the bestselling author's bid to move beyond fogged-in Forks and vampire love. But if you were hoping for some simmering passion à la Bella-Edward-Jacob from "the souls" - the parasitic invaders taking over earthling bodies - pick up the book.

Tapeworms are among humanity's oldest parasites, and were even studied by the ancient Greeks, yet a safe, effective cure to "bladder-worm" infection remains elusive. Part of the difficulty, scientists say, is that an adult tapeworm can live relatively harmlessly in a host's gut, but its larvae will spread through the host's body, like cancer, forming cysts in organs and other tissue. In some hosts, which include dogs, pigs and sheep, infection can lead to blindness, epilepsy or death.

Fly over northeastern Minnesota with "Sky Dan" and you'd see a moose. One time, he spotted 15 of them during an hour flight. The pilot was so confident, he even offered those on his aerial tours a money-back guarantee. "If you didn't see a moose, you didn't pay," Dan Anderson, 49, said. No longer.

PHOTOS: Rescued animals -- Boots, Feisty and more The state's iconic moose population has been mysteriously declining for years, a drop-off that pushed the Minnesota Department of Natural Resources this month to propose labeling moose a species of "special concern.

Anyone up for a nice, refreshing, early-autumn swim on the Nevada side of Lake Mead? Well, steer clear of Boulder Beach, which has been infected with - ick - swimmer's itch . Rangers say that an above-normal waterfowl population may be to blame for the poison ivy-like rash that was reported by at least a dozen swimmers over the weekend. Also known as schistosome cercarial dermatitis , swimmer's itch is caused when flatworm parasites that are found in some birds burrow into human skin and cause an allergic reaction.

Attempts to control malaria — which kills about 1 million people a year — have traditionally focused on the use of drugs to treat the disease and insecticides to kill mosquitoes. Now some scientists have devised a sneakier strategy: feed mosquitoes a genetically engineered bacterium that will kill the malaria parasite from within. Insecticides have a major flaw, said Marcelo Jacobs-Lorena, a malaria expert at Johns Hopkins University and an author of the new study. "When insecticides are used — say, inside of houses — many of the mosquitoes in the area get killed but some will always survive.

It is not clear how big an honor it is, but Jamaican reggae guitarist and singer Bob Marley has had his name attached to a blood-sucking parasite that infests fish living on coral reefs in Jamaica. The naming is not meant to be a sign of disrespect, said marine biologist Paul Sikkel of Arkansas State University in Jonesboro, who coined the name Gnathia marleyi to honor Marley. "I named this species, which is truly a natural wonder, after Marley because of my respect and admiration for Marley's music," Sikkel said.
