I can recommend the book by John Vacca that came out a while back, but it lacks biology and chemistry problems to some extent. A website would serve as an online bank.

Always wondered why the world didn’t simply list unsolved problems somewhere. Universities should have a poster in each departments lecture hall and toilets, listing that subject’s 10 top problems to solve to remind students to think big. Here’s Wikipedia’s list of unsolved problems in different subjects.
