"Open source" gun plans test the boundary between freedom of speech and gun control.

I support freedom of speech, and gun control. Thus, I believe it should be lawful to publish these plans, but making a gun from them can be regulated as appropriate.

A gun is a dangerous thing to own. Overall, you're safer if you don't have a gun in your house.

Direct proof that neonicotionoids kill honeybee colonies.

Other causes such as the varroa mite may contribute to the problem, but that changes nothing. We have no choice about whether the varroa mite exists. On the contrary, we can get rid of the neonicotionoids, though it will take time for the amounts accumulated in the soil to wash away.

Religiously inspired irrational fear of making genetically modified human embryos threatens to intimidate scientists out of doing important research.

There are no real ethical issues at stake here. An embryo is not a human being, and neither is a fetus. It could grow into one, and if it did it would deserve human rights; but that will not happen in these experiments.

Gene editing on real human beings raises real issues, because it could go wrong and lead to humans with various medical problems. However, one issue we probably need not worry about is that these problems would be inherited. By the time such a person is old enough to have children, we will have no difficulty making a corrective change for those children.

US citizens: call on the Democratic National Committee to support Sanders's progressive agenda.

US citizens: call on the EPA to ban neonicotinoid pesticides before its too late for bees and the plants they pollinate.
