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.

Brexit could destroy our NHS – and it would be the government's own fault

Without EU citizens, the health service will be short of 20,000 nurses in a decade.

Aneurin Bevan once said: "Illness is neither an indulgence for which people have to pay, nor an offence for which they should be penalised, but a misfortune, the cost of which should be shared by the community."

And so, in 1948, the National Health Service was established. But today, the service itself seems to be on life support and stumbling towards a final and fatal collapse.

It is no secret that for years the NHS has been neglected and underfunded by the government. But Brexit is doing the NHS no favours either.

In addition to the promise of £350m to our NHS every week, Brexit campaigners shamefully portrayed immigrants, in many ways, as as a burden. This is quite simply not the case, as statistics have shown how Britain has benefited quite significantly from mass EU migration. The NHS, again, profited from large swathes of European recruitment.

We are already suffering an overwhelming downturn in staffing applications from EU/EAA countries due to the uncertainty that Brexit is already causing. If the migration of nurses from EEA countries stopped completely, the Department of Health predicts the UK would have a shortage of 20,000 nurses by 2025/26. Some hospitals have significantly larger numbers of EU workers than others, such as Royal Brompton in London, where one in five workers is from the EU/EAA. How will this be accounted for? 

Britain’s solid pharmaceutical industry – which plays an integral part in the NHS and our everyday lives – is also at risk from Brexit.

London is the current home of the highly prized EU regulatory body, the European Medicine Agency, which was won by John Major in 1994 after the ratification of the Maastricht Treaty.

The EMA is tasked with ensuring that all medicines available on the EU market are safe, effective and of high quality. The UK’s relationship with the EMA is unquestionably vital to the functioning of the NHS.

As well as delivering 900 highly skilled jobs of its own, the EMA is associated with 1,299 QPPV’s (qualified person for pharmacovigilance). Various subcontractors, research organisations and drug companies have settled in London to be close to the regulatory process.

The government may not be able to prevent the removal of the EMA, but it is entirely in its power to retain EU medical staff. 

Yet Theresa May has failed to reassure EU citizens, with her offer to them falling short of continuation of rights. Is it any wonder that 47 per cent of highly skilled workers from the EU are considering leaving the UK in the next five years?

During the election, May failed to declare how she plans to increase the number of future homegrown nurses or how she will protect our current brilliant crop of European nurses – amounting to around 30,000 roles.

A compromise in the form of an EFTA arrangement would lessen the damage Brexit is going to cause to every single facet of our NHS. Yet the government's rhetoric going into the election was "no deal is better than a bad deal". 

Whatever is negotiated with the EU over the coming years, the NHS faces an uncertain and perilous future. The government needs to act now, before the larger inevitable disruptions of Brexit kick in, if it is to restore stability and efficiency to the health service.
