Gangtok, April 4 -- In a remarkable leap for medical technology, researchers have unveiled a pacemaker so minute it could vanish inside the tip of a syringe - in fact, it's tinier than a grain of rice. Crafted with a focus on temporary cardiac support, this dissolvable marvel may soon reshape how doctors treat fragile newborn hearts.

Created by a team at Northwestern University, the device represents a major shift away from the bulky and invasive pacemakers traditionally used in cardiac care. Published in the prestigious journal *Nature*, the research reveals a device that doesn't just perform - it disappears.

"For young patients, especially infants, size is everything," said Dr. John A. Rogers, a leading figure in bioelectronics and on...
