Should doctors tell patients about expensive, unfunded drugs?

... But the authors argue that this practice fails to respect autonomy and may not be in the patient's best interests. They believe that withholding information on the basis of what a patient would want is "a dangerous medical path to unjustified paternalism." A further ethical issue concerns the cost of publ...

...rstanding of the forces behind the changes." With respect to the North Sea, for example, researchers at the conference will show: * How large harvests of the ling fish prior to 1914 allowed cod to dominate the North Sea, causing ecologists today to rethink models of the North Sea ecosystem; * How c...

Divergent mating systems and parental conflict as a barrier to hybridization in flowering plants

...lfing groups should be competitively inferior with respect to this parental conflict. Yaniv Brandvain and David Haig examine crosses between selfing and outcrossing pairs and find that, in most cases, there are pre- and post-zygotic symptoms of outcrossers being "stronger" than selfers with regard to parenta...
