Back in my time it was the Westinghouse Science Search but now it's Regeneron (it's a biotech company which I had to look up).
Here's the press release of this year's winners, dominated by Asian-Americans.
Two signs of the times here--Westinghouse going bankrupt, ending its sponsorship of the talent search, and reinventing as nuclear energy company, and the domination of the search by people whose ancestry isn't western European.
I sort of regret the first--I think nuclear should have a role in moving away from fossil fuels--and applaud the second--the more brains from more areas we have working the better off everyone will be.
