Scientists Conduct Shark Survey Off U.S. East Coast
Sandbar, dusky and tiger sharks are among dozens of shark species living in the coastal waters off the U.S. East Coast. Little is known about many of the species, but...
Biological Clocks Of Insects Could Lead To More Effective Pest Control
Researchers have discovered that the circadian rhythms or biological "clocks" in some insects can make them far more susceptible to pesticides at some times of the day instead of others.
Fungus Found In Humans Shown To Be Nimble In Mating Game
Researchers have determined that Candida albicans, a human fungal pathogen, pursues both same-sex and the more conventional opposite-sex mating.

Canadian scientists identify gene that makes water striders glide across water
Water striders, the familiar semi-aquatic bugs gliding across the lake at the cottage, have a novel body form that allows them to walk on water. This was not always the...
New data confirms imidacloprid remains highly effective
Bayer Animal Heath announced today at the 22nd World Association for the Advancement of Veterinary Parasitology (WAAVP), Calgary, Canada the latest results of a large-scale, international, independent Flea Susceptibility Monitoring...
Technique enables efficient gene splicing in human embryonic stem cells
A novel technique allows researchers to efficiently and precisely modify or introduce genes into the genomes of human embryonic stem cells (ESCs) and induced pluripotent stem (iPS) cells, according to...
Possible Genetic Links Between Environmental Toxins And Multiple Myeloma
Several SNPs associated with bone disease in myeloma have been identified. Several of these SNPs are believed to be associated with toxin metabolism and/or DNA repair. Although these findings are...
