High-tech traps are designed to eradicate the feral cats that threaten Australia's small wildlife.

Maybe in the future it will be possible to eradicate other feral animals that endanger unusual local species in other places.

Khairuldeen Makhzoomi, who moved to the US from Iraq as a child, was taken off a flight in the US because another passenger found it suspicious that he was speaking Arabic.

US citizens: tell Congress you support the bill to impose stricter conditions on US arms for Salafi Arabia.

The country's official name is "Saudi Arabia", but "Salafi Arabia" reminds people of that country's most important export: an oppressive and fanatical form if Islam.

Why does Obama threaten to veto a bill that would allow victims of the September 2001 terror attacks to sue foreign governments if they are responsible?

Maybe because he doesn't want the US government to be sued for things like drone bombings. Or maybe he is defending Salafi Arabia. Both reasons are bad. Maybe it is both. He may not want Yemenis to sue the US for providing weapons that Salafi Arabia is using to bomb civilians there. Both Sanders and Clinton support the bill, but Sanders also calls for publication of what the government's report said about Salafi Arabia.

As for the Salafi threat to sell some assets in the US, the US should not cower in fear of that. On the contrary, it suggests that Salafi Arabia has reason to expect it will lose such a lawsuit. The US needs to stop supporting Salafi Arabia in any case, so that it can't keep spreading fanatical Islam around the world.

South Australia already gets half its electricity from wind and solar power.

A program to subsidize building owners in buying batteries would quickly go the rest of the way.
