Check out this terrifying robo-rat: created to make other rats depressed

The rising armies are at our door.

The life of a lab rat seemed bleak enough, but it's only set to get tougher with the invention of a robotic rodent whose sole purpose is to harass its living counterpart.

Rats are regularly used to test drugs that tackle mental conditions, including depression. This means that scientists need a ready supply of depressed rats at their disposal in order to test drugs and see how well medication can alleviate their symptoms. The robo rat, or WR-3, is seemingly more than up to the task with its various creepy abilities, which include stalking, constant physical attacks on its victim, and attacks that are triggered whenever the live rat moves.

Bred and kept alive simply to serve as walking experiments for medical research - great for us, not so great for them - you might think a lab rat's existence is drab enough without the introduction of a mechanical bully, but scientists are hoping that the robo rat will shed some light on what triggers mental disorders.

Unsurprisingly, the researchers found that if a rat is constantly harassed by a robot when it is young and vulnerable, and then intermittently terrorised in adulthood then this is likely to make it very depressed.

It's possible to make a rat depressed by other means - forced swimming for long periods, constant running - but these methods aren't usually what induce depression in humans so the researchers wanted the rats to be gloomy based on the response to certain behaviours.

Quite what this means for medical research is hard to gauge - the researchers claim that the less a rat moves the more depressed it is. Of course, it could just be terrified of the strange metal thing that keeps bashing into it. But here's hoping some significant findings come out of all of this, otherwise we're left with a horde of traumatised rats and an army of violent robotic rodents, and little to show for it.

How Theresa May laid a trap for herself on the immigration target

When Home Secretary, she insisted on keeping foreign students in the figures – causing a headache for herself today.

When Home Secretary, Theresa May insisted that foreign students should continue to be counted in the overall immigration figures. Some cabinet colleagues, including then Business Secretary Vince Cable and Chancellor George Osborne wanted to reverse this. It was economically illiterate. Current ministers, like the Foreign Secretary Boris Johnson, Chancellor Philip Hammond and Home Secretary Amber Rudd, also want foreign students exempted from the total.

David Cameron’s government aimed to cut immigration figures – including overseas students in that aim meant trying to limit one of the UK’s crucial financial resources. They are worth £25bn to the UK economy, and their fees make up 14 per cent of total university income. And the impact is not just financial – welcoming foreign students is diplomatically and culturally key to Britain’s reputation and its relationship with the rest of the world too. Even more important now Brexit is on its way.

But they stayed in the figures – a situation that, along with counterproductive visa restrictions also introduced by May’s old department, put a lot of foreign students off studying here. For example, there has been a 44 per cent decrease in the number of Indian students coming to Britain to study in the last five years.

Now May’s stubbornness on the migration figures appears to have caught up with her. The Times has revealed that the Prime Minister is ready to “soften her longstanding opposition to taking foreign students out of immigration totals”. It reports that she will offer to change the way the numbers are calculated.

Why the u-turn? No 10 says the concession is to ensure the Higher and Research Bill, key university legislation, can pass due to a Lords amendment urging the government not to count students as “long-term migrants” for “public policy purposes”.

But it will also be a factor in May’s manifesto pledge (and continuation of Cameron’s promise) to cut immigration to the “tens of thousands”. Until today, ministers had been unclear about whether this would be in the manifesto.

Now her u-turn on student figures is being seized upon by opposition parties as “massaging” the migration figures to meet her target. An accusation for which May only has herself, and her steadfast politicising of immigration, to blame.
