To help these smokers quit, researchers recommend addressing their psychological distress and developing treatments that go beyond nicotine dependence.
Researchers tracked black-tailed deer before, during, and after the Mendocino Complex Fire, finding that all 18 deer survived. Despite burned areas with no vegetation, most deer returned home within hours, potentially due to their loyalty to habitat. However, some deer's body condition declined as they expanded their range.
