40-year math mystery and 4 generations of figuring
Atlanta GA (SPX) May 30, 2016
This may sound like a familiar kind of riddle: How many brilliant mathematicians does it take to come up with and prove the Kelmans-Seymour Conjecture? But the answer is no joke, because arriving at it took mental toil that spanned four decades until this year, when mathematicians at the Georgia Institute of Technology finally announced a proof of that conjecture in Graph Theory. Their research was funded by the National Science Foundation. Graph Theory is a field of mathematics that's instrumenta ... read more

Supermassive black hole wind can stop new stars from forming Scientists have uncovered a new class of galaxies with supermassive black hole winds that are energetic enough to suppress future star formation. Devoid of fresh young stars, red and dead galaxies m ... more		Doubling down on Schrodinger's cat Yale physicists have given Schrodinger's famous cat a second box to play in, and the result may help further the quest for reliable quantum computing. Schrodinger's cat is a well-known paradox ... more		Engineers discover a new gatekeeper for light Imagine a device that is selectively transparent to various wavelengths of light at one moment, and opaque to them the next, following a minute adjustment. Such a gatekeeper would enable powerful an ... more
				Beating the limits of the light microscope, one photon at a time The world's most advanced light microscopes allow us to see single molecules, proteins, viruses and other very small biological structures. But even the best microscopes have their limits.

				How Giant Black Holes Formed So Quickly Using data from NASA's Great Observatories, astronomers have found the best evidence yet for cosmic seeds in the early universe that should grow into supermassive black holes. Researchers combined d ... more		Astronomers find giant planet around very young star In contradiction to the long-standing idea that larger planets take longer to form, astronomers have reported the discovery of a giant planet in close orbit around a star so young that it still reta ... more
