TURTLE TOUCHERS: Tourists in Costa Rica made international headlines this year when they mobbed Ostional Beach on the country’s Pacific coast, scaring off scores of olive ridley sea turtles that had come ashore to lay eggs in the sand.© SINDICATO DE TRABAJADORES DE MINAE

We know that humans are able to drive rapid phenotypic change in other species. If individuals selectively habituate to humans—particularly tourists—and if invasive tourism practices enhance this habituation, we might be selecting for or creating traits or syndromes that have unintended consequences.

Our study results suggest that if you are 40 years old now, you’d have to eat even less and exercise more than if you were a 40-year-old in 1971 to prevent gaining weight. However, it also indicates...

Fear of potential criticism or backlash dilutes our capacity to lead in public health.

Immigration to my country harms me, it harms my family, it harms my people. Whoever invites or welcomes immigrants to Europe and Germany is my enemy. Immigration unnecessarily defers the collapse of capitalism, its final crisis.

I’d say not being able to use Treefinder would be no great loss to anyone. I would stop using [Treefinder] just on general principle, even if we had to resort to using pencil and paper.

Sandra Baldauf, biologist at Uppsala University in Sweden who had previously used Treefinder in published papers, talking to Science about the multiple alternatives to the program (September 29)
