Cocoa beans are naturally rich in flavanols, but these compounds can get stripped out by the time you get to a chocolate bar. Researchers use cocoa powder specially prepared to preserve the flavanols to figure out how they affect the brain.

Our nearest star is about to pull a once-in-11-years move by swapping its north and south magnetic poles.
The sun's polarity switch is a natural part of "solar max" — the period of peak activity during what averages out to be roughly an 11-year cycle. According to NASA, this year will mark the fourth time since 1976 that scientists have observed the 180-degree pole flip.

Here's what the Swedish artist Oscar Reutersvard did. In 1934, he got himself a pen and paper and drew four cubes, like this.
Then he drew some more, like this.
And, then — and this is where he got mischievous — he drew one more set, like this.
He called this final version "Impossible Triangle of Opus 1 No. 293aa." I don't know what the "293aa" is about, but he was right about "impossible." An arrangement like this cannot take place in the physical universe as we know it.
