| Mini Surgical Robot Crawls Over Beating Heart
US scientists have made a mini prototype robot that crawls over the surface of a beating heart and performs simple repairs without major surgery.
A report in this week's New Scientist magazine describes how the HeartLander, invented by robotics experts Dr Cameron Riviere and colleagues at Carnegie Mellon University in Pittsburgh, Pennsylvania, has injected dye and attached pacemaker leads to beating hearts inside live pigs.
The surgeon controls the caterpillar-like device, which weighs about the same as an egg and is half the length of a thumb, using a joystick, and tracks it with a visual monitor that uses either X-ray video or a magnetic tracker.
It is hoped that one day such robots will help heart surgeons remove damaged tissue or even inject stem cells directly into the heart without having to stop it beating.
Radio Disney Welcomes Miss Amy To World Cafe Live!
"The perpetrator of the Penguin Dance returns to World Cafe Live!" bubbled Kathy O'Connell of WXPN's Kids Corner last year as she introduced Miss Amy to a cheering crowd of youngsters and parents. Always a crowd pleaser, Miss Amy & Her Big Kids Band will perform this year on April 21st as Radio Disney hosts the Dodge Caravan Peanut Butter & Jams music series held at this renowned Philadelphia venue. Miss Amy has been very active over the past year performing for fundraisers of national organizations including March of Dimes and United Way, and participating in "Musicians On Call" where she volunteers her time to bring smiles to the kids and parents at The Children's Hospital of Philadelphia (see http://www.xpn.org/moc.php for more). Recently, Miss Amy stepped up as a celebrity spokesperson for a local cause, to help the Ewing NJ High School Robotics Team gain some sponsorship from Delta Airlines to help cover costs for travel to Atlanta, GA.

The Other: A Guide to Indian Movie Stars - Part 4: The Beauties
No other medium is more suited for magnifying physical beauty than the cinema. Women in particular are the darlings of this particular art form. Beautiful actresses are synonymous with the movies. The majority of the industry's glamour is linked to starlets, so much so that the entire Academy Awards Ceremony is more of a showcase for their poise and resplendent gowns than it is for the outstanding films and performances of that year. The enchantment of the medium is the enduring memory of images, and many are of beautiful faces: Audrey Hepburn's pixie grin as she tilts her sunglasses in Breakfast at Tiffany's, Greta Garbo's stony, enigmatic face in the closing shot of Queen Christina, Grace Kelly smiling surreptitiously behind the steering wheel in To Catch a Thief. Indian cinema's leading ladies are a bevy of Old World beauties.
