It appears that

topologist Martin Dunwoody has proposed a general

proof for the Poincare Conjecture. As of April 7, 2002, this proof is in

preprint, available for now at http://www.maths.soton.ac.uk/~mjd/Poin.pdf.

As I am not a

mathematician, I will not attempt to provide a layman's explanation of the conjecture. It is worth noting that if the proof stands, Dr. Dunwoody may be a very wealthy man - the Clay Institute prize is

one million dollars!
