BOSTON -- Have you ever wondered whether antibacterial soaps are better than regular soap? Researchers at the University of Michigan don't believe they are.

They reviewed 27 different studies on soaps and found no difference in the number of infectious diseases the soaps prevented. There was also no difference in the amount of bacteria still lingering on the hands afterward.

The study also suggested using antibacterial products may make you become resistant to common antibiotics.

Soda, Diabetes Link

There's growing evidence that sugary sodas are bad for us.

According to researchers at Rutgers University, high-fructose corn syrup found in diet sodas has the potential to trigger cell and tissue damage that could cause diabetes.

But they also found an extract in tea could reverse the effect. High fructose corn syrup is found in countless foods and beverages, including non-diet sodas, baked goods and condiments.

Stem Cells

A new study from the University of Washington found stem cells may one day be able to repair hearts after a heart attack.

Research in rats showed that human stem cells could both differentiate into heart cells and remain viable.

The size of the grafts were up to 10 percent of the heart's size. The researchers hope to try the technique on humans within three years.
