Let's make this birthday one to remember.

69 years old (Born on February 19, 1956)

Happy Birthday, Roderick MacKinnon! May your special day be more exciting than discovering potassium channels in bacteria—though let's face it, that bar is exceptionally high. Your groundbreaking use of X-ray crystallography to unveil the three-dimensional structure of ion channels earned you a Nobel Prize; clearly you've mastered channel-surfing at an atomic level!

Thank you for showing us all how even tiny molecules can electrify science—and chemists too! Today we celebrate not only your incredible discoveries but also your inspiring curiosity and boundless dedication. Here's hoping this next year opens many doors...or better yet, lots more fascinating "channels". Happy birthday!
