Astronomers spot another neutron star merger, the first BEC created in space, and how Leonardo da Vinci’s vision disorder may have influenced his art are among this week’s physics highlights.
Me at Ars Technica:
Probable Cause: “Fixed mindsets” might be why we don’t understand statistics. Study finds people prefer complicated methods because that’s what they’re used to.
Making a Scene: What watching “Forrest Gump” tells us about how we store memories. People’s brains respond most strongly to transitions between events.
Crying in our beer: Barley shortages from climate change could mean less beer worldwide. Even modest warming leads to more drought and excessive heat for barley crops.
The Dead Will Rise: Fifth-century child’s skeleton shows evidence of “vampire burial”: Dubbed the “Vampire of Lugnano,” the skull had a rock stuffed in its mouth to keep it from rising from grave.

In a shocking move, Netflix cancels Marvel’s Iron Fist after two seasons. After a much-improved second season, the series was poised for a strong season 3.
Sweet Christmas: Another Defender bites the dust as Netflix cancels Luke Cage, just one week after pulling the plug on Iron Fist: Harlem’s hero is the latest casualty as Netflix does a little housecleaning, and I am super bummed about it.
