Why do predators and parasites eavesdropping on mating signals of their prey preferentially attack individuals producing certain types of call? Predators could use information encoded in calls to decide whom to attack.

A new study shows a significantly increased risk of HIV infection among women with a common sexually transmitted disease, trichomoniasis.

Scientists at UCLA and NYU have deciphered the genome of the parasite causing trichomoniasis, and their research may lead to new approaches to improve the diagnosis and treatment of this common sexually transmitted disease.

Researchers have decoded the genetic makeup of the parasite that causes trichomoniasis, one of the most common sexually transmitted infections (STIs), revealing potential clues as to why the parasite has become increasingly drug resistant and suggesting possible pathways for new treatments, diagnostics and a potential vaccine strategy.

More than a decade of searching for factors that make the common parasite Toxoplasma gondii dangerous to humans has pinned 90 percent of the blame on just one of the parasite's approximately 6,000 genes.
