Study finds wide attitude gap on wolves

A recent survey found that attitudes towards wolves in Wisconsin are shaped more by cultural factors than individual experiences. Moderate support exists for wolf recovery statewide, with 73% of residents favoring maintaining or increasing wolf numbers. However, hunters and livestock producers exhibit greater intolerance towards wolves.

New guidelines for drug studies for relapsed prostate cancer patients

The new guidelines recommend limiting treatment to patients at expected risk for metastatic disease and only evaluating drugs with demonstrated clinical activity. The guidelines also require significant proportion of patients to show decline or no increase in PSA and prostate-cancer specific survival.
