| Quote of the Week |
The downside of skepticism: it can easily turn into an arrogant position of a priori rejection of any new phenomenon or idea, a position that is as lacking in critical thinking as the one of the true believer, and that simply does not help either science or the public at large. |
Massimo Pigliucci, Italian-American philosopher and biologist |

Item #1: A recent analysis confirms that the current red spot of Jupiter is the same spot first observed by Cassini in 1665, making it at least 360 years old.[7]
Item #2: By analyzing tool-making researchers find that humans began cumulative culture around 600,000 years ago.[8]
Item #3: For the first time astronomers witness the activation of a massive galactic black hole into an active galactic nucleus.[9]

Skeptical Quote of the Week (1:46:47)
The downside of skepticism: it can easily turn into an arrogant position of a priori rejection of any new phenomenon or idea, a position that is as lacking in critical thinking as the one of the true believer, and that simply does not help either science or the public at large.
– Massimo Pigliucci (1964-present), Italian-American philosopher and biologist, from Nonsense on Stilts: How to Tell Science from Bunk
