While Mercury has no plate tectonics in the terrestrial sense, crustal shrinking still qualifies as tectonic activity. It could even trigger Mercury-quakes.

New Ostrich-Mimic Dinosaur Species Identified “We histologically thin-sectioned the femur of Rativates evadens to analyze its growth and determined it was at least eight years old and nearly adult-sized at the time of death,” said Thomas Cullen, from the University of Toronto. .... “This suggests that there are at least two differently-sized, but closely-related dinosaur species that lived together on the ancient landscape, similar to what we see today in the closely related predators like foxes, coyotes and wolves,” said Dr. Claudia Schröder-Adams, of Carleton University.

On hearing voices: Psychics are much more likely to perceive the voices as positive or helpful and as experiences that can be controlled, according to a new study published Sept. 28 in the journal Schizophrenia Bulletin. "We have known for some time that people in the general population can have the experience of hearing voices—sometimes frequently—without the need for psychiatric intervention," said Albert Powers, a psychiatry fellow [at Yale] and lead author of the study.
