This week, biologists discovered a new cellular organelle that's like "a new recycling center within the cell." Wild-growing tomatoes in the Galápagos are de-evolving. And geologists at the University of Southampton detected deep Earth pulses beneath Africa. Plus: Brain network functionality differs in people with psychopathic personality; sharks have a surprising vulnerability; and people with the highest measured IQ make better probabilistic p…
