Los negociadores sobre el clima que se reúnen en Alemania esta semana aún están a tono con el éxito del Acuerdo de París hace dos años. Pero a medida que comienzan a armar un libro de reglas para garantizar que se cumplan las promesas nacionales hechas en París, llega una dosis dura de realidad.

Study: Serving Water With School Lunches Could Prevent Child, Adult Obesity
Encouraging children to drink plain water with their school lunches could prevent more than half a million youths in the U.S. from becoming overweight or obese, and trim the medical costs and indirect societal costs associated with these problems by more than $13 billion, a new study suggests.
Powering Saturn's Active Ocean Moon
Heat from friction could power hydrothermal activity on Saturn's moon Enceladus for billions of years if the moon has a highly porous core, according to a new modeling study by European and U.S. researchers working on NASA's Cassini mission.
The study, published today in the journal Nature Astronomy, helps resolve a question scientist have grappled with for a decade: Where does the energy to power the extraordinary geologic activity on Enceladus come from?
Use of Glow Sticks in Traps Greatly Increases Amphibian Captures in Study
With amphibian populations declining around the world and funds to find the causes scarce, a team of Penn State researchers has shown that an unorthodox tactic will make it easier and therefore less expensive to capture adult salamanders and frogs.
With Climate Change, Mount Rainier Floral Communities Could 'Reassemble' With New Species Relationships, Interactions
Central to the field of ecology is the mantra that species do not exist in isolation: They assemble in communities — and within these communities, species interact. Predators hunt prey. Parasites exploit hosts. Pollinators find flowers.
