Study: Origin of cholera epidemic in Haiti is in humans, not nature

After studying the DNA of the strain of cholera responsible for the outbreak in Haiti, researchers believe this disease was brought to the Caribbean nation by humans.

Researchers used cutting-edge DNA testing to identify the origins of the bacteria responsible for the large cholera outbreak.  By sequencing the genome of this strain and analyzing the DNA from strains found in Latin America and South Asia, researchers found this Haitian strain of cholera is nearly identical to strains circulating in South Asia, according to a study published online in the New England Journal of Medicine on Thursday.  However, it was distinct from the strain in Latin America, says lead author Dr. Matthew Waldor, a physician and researcher at the Harvard School of Medicine.

Can your imagination help you stop eating?

A powerful craving for chocolate candy takes hold. Imagine popping that chocolate into your mouth. Then crunch through its candy shell, chew the chocolate center as it melts in your mouth and swallow. Then go through this imaginary motion 29 more times.

The repetitive imagery of eating could help people consume less, according to a study released Thursday in the journal Science.

“If we imagine performing it, if we’re chewing and swallowing and imagining consumption, it decreases our desire for the food we imagine eating,” said Carey Morewedge, lead author of the study. FULL POST

Sex: Should women be more like men?

In the very first episode of "Sex and the City," Carrie poses the question,  “In an age where women enjoy the same successes as men, why shouldn’t they also be able enjoy sex like men?” She was, of course, referring to the male ability to indulge in sex casually, freely, and without a sense of emotional attachment: sex for the sake of sex. And clearly, the phenomenon of the TV series itself, as well as the culture of hooking up of which it was part and parcel, has answered its own question: Yes, a woman can have sex like a man—and then some!

But maybe the real question isn’t whether a woman can have sex like a man, but if she should. At Good in Bed, our experts are debating this topic and we don’t always agree.
