New research suggests diabetes transmitted from parents to children

A new study in the September issue of the Journal of Lipid Research suggests an unusual form of inheritance may have a role in the rising rate of diabetes, especially in children and young adults, in the United States. DNA is the primary mechanism of inheritance; kids get half their genes from...

Is political orientation transmitted genetically?

As reported in this week's issue of "New Scientist" magazine, research by Rice University professor of political science John Alford indicates that what is on one's mind about politics may be influenced by how people are wired genetically. Alford, who has researched this topic for a number of y...

Scientists sequence genome of parasite responsible for common sexually transmitted infection

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, diagnos...

Teens unaware of sexually transmitted diseases until they catch one, Carnegie Mellon study finds
