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.

“It’s scary to do it again”: the five-year-old fined £150 for running a lemonade stand

Enforcement officers penalised a child selling home-made lemonade in the street. Her father tells the full story. 

It was a lively Saturday afternoon in east London’s Mile End. Groups of people streamed through residential streets on their way to a music festival in the local park; booming bass could be heard from the surrounding houses.

One five-year-old girl who lived in the area had an idea. She had been to her school’s summer fête recently and looked longingly at the stalls. She loved the idea of setting up her own stall, and today was a good day for it.

“She eventually came round to the idea of selling lemonade,” her father André Spicer tells me. So he and his daughter went to their local shop to buy some lemons. They mixed a few jugs of lemonade, the girl made a fetching A4 sign with some lemons drawn on it – 50p for a small cup, £1 for a large – and they carried a table from home to the end of their road. 

“People suddenly started coming up and buying stuff, pretty quickly, and they were very happy,” Spicer recalls. “People looked overjoyed at this cute little girl on the side of the road – community feel and all that sort of stuff.”

But the heart-warming scene was soon interrupted. After about half an hour of what Spicer describes as “brisk” trade – his daughter’s recipe secret was some mint and a little bit of cucumber, for a “bit of a British touch” – four enforcement officers came striding up to the stand.

Three were in uniform, and one was in plain clothes. One uniformed officer turned the camera on his vest on, and began reciting a legal script at the weeping five-year-old.

“You’re trading without a licence, pursuant to x, y, z act and blah dah dah dah, really going through a script,” Spicer tells me, saying they showed no compassion for his daughter. “This is my job, I’m doing it and that’s it, basically.”

The girl burst into tears the moment they arrived.

“Officials have some degree of intimidation. I’m a grown adult, so I wasn’t super intimidated, but I was a bit shocked,” says Spicer. “But my daughter was intimidated. She started crying straight away.”

As they continued to recite their legalese, her father picked her up to try to comfort her – but that didn’t stop the officers giving her stall a £150 fine and handing them a penalty notice. “TRADING WITHOUT LICENCE,” it screamed.

“She was crying and repeating, ‘I’ve done a bad thing’,” says Spicer. “As we walked home, I had to try and convince her that it wasn’t her, it wasn’t her fault. It wasn’t her who had done something bad.”

She cried all the way home, and it wasn’t until she watched her favourite film, Brave, that she calmed down. It was then that Spicer suggested next time they would “do it all correctly”, get a permit, and set up another stand.

“No, I don’t want to, it’s a bit scary to do it again,” she replied. Her father hopes that “she’ll be able to get over it”, and that her enterprising spirit will return.

The Council has since apologised and cancelled the fine, and called on its officials to “show common sense and to use their powers sensibly”.

But Spicer felt “there’s a bigger principle here”, and wrote a piece for the Telegraph arguing that children in modern Britain are too restricted.

He would “absolutely” encourage his daughter to set up another stall, and “I’d encourage other people to go and do it as well. It’s a great way to spend a bit of time with the kids in the holidays, and they might learn something.”

A fitting reminder of the great life lesson: when life gives you a fixed penalty notice, make lemonade.
