Here’s what science has taught us in the past week:

• First off, you can take a look at my new interview with Cliff Pickover about The Medical Book, and how medical science has (and hasn’t) changed over the years.
• For the first time ever, the rare decay of a Bs meson into two muons has been observed. For every billion times the decay goes the other way, it goes this way just three times. This result rules out some of the simplest supersymmetry models, meaning scientists might need to start looking for alternative explanations for dark matter and the fundamental structure of the universe.
• A fish-eating sea sponge is discovered. It’s not the first sponge discovered to do this, but it was observed in action with unprecedented detail. The link will take you to a video of it.
• Scientists have successfully removed an extra chromosome that causes Down syndrome from a culture of cells.
• It’s possible human intelligence reached its height thousands of years ago, and has been in decline since that time.
