It was gratifying to see the photograph of the Johns Hopkins students who have developed the new device, "FastStitch," for closing abdominal wounds ("The Future of Suture?" Nov. 1). Why? Because they were such a conglomeration of ethnicities and races and cultures.
I hope the young supporters of the perennial isolationist presidential candidate Ron Paul will see the value in our porous borders. Students, and permanent residents, come to this country, make their contributions, and either stay, making ours a better place to live, or take their knowledge home and make their own countries better.
This brilliant exchange of knowledge benefits everyone. I hope the U.S. is always a beacon of hope and light for the world, attracting the best and brightest to our shores.
