It's not especially pleasing to write about death in the first column of the New Year, but there's a lot of it about.
In Iraq, Saddam Hussein has been executed. In Libya, five Bulgarian nurses and a Palestinian doctor have been sentenced to death on charges of infecting hundreds of Libyan children with HIV. In the United States, many death-row inmates are wondering if they will escape execution, as courts agonize over whether or not execution by lethal injection is humane. And in Japan, 21 people -- including Aum Shinrikyo founder Shoko Asahara -- have had their death sentences finalized for this year.
Execution is a personal matter. If you believe in it, or not, depends on your own feelings about crime and punishment.

The answer is that, in one way or another, science impacts on the death penalty in all four of the cases mentioned above.
