Washington, April 3 : In what may eventually hold great significance for patients who have suffered myocardial damage as a result of a heart attack, a study has shown that cells in a human heart can develop into adulthood and their age is, on average, six years younger than the individual.

Scientists from the Lawrence Livermore National Laboratory, the Karolinska Institute, Universite Claude Bernard Lyon, Lund University, and Lund University Hospital made these findings by using the amount of carbon 14 in the atmosphere from above-ground nuclear testing in the 1950s and 1960.

The 37-year-old's home is in an idyllic German village of 3,000 outside Stuttgart, more known for its peaceful surroundings than political persecution.

Miami  - Desperate Rafael Nadal saved two of three match points with aces but couldn't hold off the momentum of hard-charging Argentine Juan Del Potro, taking a 6-4, 3-6, 7-6 (7-3) defeat Thursday in the quarter-finals of the Miami Masters.

The three-hour epic handed Del Potro his first victory over Spain's number 1 after three previous defeats. The youngster had not won a single set in the series before stepping onto court in front of an overwhelmingly Latin crowd in South Florida.
