The objections surrounding the use of embryonic stem cells in organ and tissue reconstruction could be silenced if clinical trials for a new strain of stem cells derived from liposuctioned fat get a nod of approval from the FDA.

Physicians and veterinarians agree: If it looks like a duck, walks like a duck, and is sick like a duck, it's best for it to be treated by someone trained to treat a duck.
Faced with such a scenario, physicians would be armed only with what they know about human biology. And that doesn't go very far, says Rika Maeshiro, the director of Public Health and Prevention Projects for the Association of American Medical Colleges.
It's 2:30 in the afternoon in the Dominican Republic, and Karen Velline, a 66-year-old grandmother from Cold Spring, Minnesota, is lying on an operating table, swaddled in sterile surgical sheets. She's just moments away from a procedure so experimental that no doctor will perform it on U.S. soil. Yet she calmly stares up at the ceiling, more excited than anxious.
The loss of a tooth is a minor deformity and a major pain. Although dental implants are available, the healing process can take months on end, and implants that fail to align with the ever-growing jawbone tend to fall out. If only adult teeth could be regenerated, right?
According to a study published in the latest Journal of Dental Research, a new tissue regeneration technique may allow people to simply regrow a new set of pearly whites.
For two years, Charles Okeke, 43, was just another patient confined to a hospital while awaiting a human heart transplant. Now, he's the country's first test subject for a battery-operated, backpack-sized console, called the Freedom Driver, which will power his artificial heart and allow him to go home for the first time in two years.
Though we may often think of cholera as a disease of the past, virtually eradicated when John Snow famously linked an 1854 outbreak of the epidemic in London to an infected water well on Broad Street, it still poses a threat in almost every single developing country in the world. Over 150 years after Snow essentially founded modern epidemiology, a team of American scientists are using remote satellite imaging to predict cholera outbreaks before they occur.
