"One of the most important unsolved problems in mathematics may have been solved, retired mathematician Michael Atiyah is set to claim on Monday. In a talk at the Heidelberg Laureate Forum in Germany, Atiyah will present what he refers to as a “simple proof” of the Riemann hypothesis, a problem which has eluded mathematicians for almost 160 years."

Its way way way above my understanding, nevertheless I do generally read up on lots of maths topics and enjoy it even when I have no clue about what they talk about sometimes

For an explanation of what this is, this is a great numberphile youtube video.
