Mars may have formed out where the asteroid belt is now, far from its planetary neighbors, Thomas Sumner reported in “New proposal reimagines Mars’ origin” (SN: 5/27/17, p. 14).
Readers online were fascinated by Mars’ origin story. “There seemed to be evidence of actual seas on early Mars,” stargene wrote. “How can this be finessed into the idea of Mars living out...
One lab full of rats looks pretty much the same as another. But visiting a lab in Siberia, geneticist Alex Cagan can distinguish rats bred to be tame from those bred to be aggressive as soon as he opens the lab door.
“It’s a completely different response immediately,” he says. All of the tame rats “come to the front of the cage very inquisitively.” The aggressive rats scurry to the backs...
Long before humans domesticated other animals, we may have domesticated ourselves.
Over many generations, some scientists propose, humans selected among themselves for tameness. This process resulted in genetic changes, several recent studies suggest, that have shaped people in ways similar to other domesticated species.
Tameness, says evolutionary biologist and primatologist...
John Archibald Wheeler was fond of clever phrases.
He made the term “black hole” famous in the 1960s. He also coined the now-familiar “wormhole” and “quantum foam.” While further pondering the mystery of quantum physics at the University of Texas at Austin during the 1980s, Wheeler repeatedly uttered his favorite interrogative slogan: “How come the quantum?” And from those ponderings...
