A new study finds that relatively early into tobacco addiction, teens experience many of the same negative psychological effects during abstinence as adults do, with a couple of exceptions. The data can inform efforts to improve the efficacy of quitting and withdrawal treatment programs.

PROVIDENCE, R.I. [Brown University] — Abstinence from smoking seems to affect teens differently than adults in a couple of ways, but a new study provides evidence that most of the psychological difficulties of quitting are as strong for relatively new, young smokers as they are for adults who have been smoking much longer.

“Adolescents are showing — even relatively early in the dependence process — significant, strong, negative effects just after acute abstinence from smoking,” said L.

We chose a broad array” of factors to study. (more…)

ANN ARBOR, Mich.— Rising sea levels, melting glaciers, more intense rainstorms and more frequent heat waves are among the planetary woes that may come to mind when climate change is mentioned. Now, two University of Michigan researchers say an increased risk of avian influenza transmission in wild birds can be added to the list.

Population ecologists Pejman Rohani and Victoria Brown used a mathematical model to explore the consequences of altered interactions between an important species of migratory shorebird and horseshoe crabs at Delaware Bay as a result of climate change. (more…)
