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.

The players make their mistakes on the pitch – I make mine on the page

I find that if I watch three live games in a weekend, which often happens, I have totally forgotten the first two by the time the third comes up.

I was a bit humiliated and ashamed and mortified last week because of letters in this magazine about one of my recent columns. Wait till I see the Correspondence editor: there must be loads of nice letters, yet he or she goes and prints not just one, but two picking me up on my mistakes. By the left.

But mainly, my reaction was to laugh. Typical, huh, I’ve gone through life spelling things wrong, with dates dodgy, facts fictional – will I ever learn?

John Lennon did not use a watch. He maintained that he had people on the staff who would tell the time. I don’t wear a watch, either, but for different reasons. I want to get my wrists brown and I hate carrying anything.

By the same milk token, I don’t worry about my spelling. Like Lennon, I expect others to clear up after me. Surely the subs should have spotted it was a typo, that it is 64 years since 1951, not 54 as I wrote? What do they do all day? The other mistake was about replays in the League Cup: too boring to repeat, you would only yawn.

I usually try to get the spelling right the first time I use a word, then bash on, letting it come out any old way, intending to correct it later. Is it Middlesbrough or Middlesborough? Who cares? I’ll check later. Then I forget.

I was so pleased when Patrick Vieira left Arsenal. I found those ten seasons a nightmare, whenever I realised his surname was lumbering into vieiw (I mean “view”). Why couldn’t I memorise it? Mental laziness. The same reason that I don’t know the phone numbers of any of my children, or the correct spelling of my grandchildren’s names, Amarisse and Siena. I have to ask my wife how many Ss and how many Ns. She knows everything. The birthday of every member of the royal family? Go on, ask her.

I might be lazy on piddling stuff such as spelling but I like to think my old brain is still agile. I have three books on the go which are hellishly complicated. I have the frameworks straight in my head but I don’t want to cram anything else in.

It can be a bit embarrassing when writing about football, though. Since sport was invented, fans have been making lists, trotting out facts, showing off their information. As a boy, I was a whizz on the grounds of all 92 League clubs, knew the nicknames of all the clubs. It’s what you did. Comics like Adventure produced pretty colour charts full of such facts. I don’t remember sitting down and learning it all. It just went in, because I wanted it to go in.

Today, the world of football is even madder on stats than it ever was. I blame computers and clever graduates who get taken on by the back pages with nothing else to do but create stats. And TV, with its obsession with possession, as if it meant anything.

I find that if I watch three live games in a weekend, which often happens, I have totally forgotten the first two by the time the third comes up. Not just the score but who was playing. When Wayne Rooney or whoever is breaking records, or not, my eyes go glazed, refusing to take in the figures. When I read that Newcastle are again winless in their first seven League games now, I start turning the pages. If I get asked who won the Cup in 1923, my immediate answer is HowthefeckdoIknow. Hold on, I do know that. It was the first Cup final at Wembley, won by Bolton Wanderers. I remember that, having been there. I don’t know the dates of any other Cup final winners. England’s World Cup win? That was 1966 and I really was there.

I love football history (I’ve written three books about it) but it’s the players and the history of the clubs, the boots and strips, development in the laws, that’s what I enjoy knowing. Spellings and dates – hmm, I do always have to think. Did the Football League begin in 1888 or 1885? If I pause for half a second, I can work it out. Professional football came in first, which must have been 1885, so the Football League came later. Thus the answer is 1888. Bingo. Got it.

But more often than not, I guess, or leave it out. So, sorry about those mistakes. And if you’ve spotted any today, do keep it to yourself.
