brazil wednesday icehockey almost. there has been a fatality in the french hostage story from friday get the updates at the top of the hour but. those who knew him when you don't. see. what. ted space. left alone they. claim to know. that. if you speak french.

this is a story of one of africa's giants. know his teeth on that shot. and his neck isn't that a long. list giant is rather modest and keeps a low profile that's not him either. people are often scared of this particular giant but he is nowhere near as dangerous as that one. is a friendly giant every day with the possible exception of weekends he saves human

lives. his name is isaac the giant power grat. and i like his brothers and sisters he was born with a passion for travel. isaac's birthplace was a special training center in tanzania. it's called which stands for development of landmine detection equipment that's what isaac is these are mine sniffing rat. rats are everywhere they are sociable

to all circumstances and they've lifted with humanity since ever. they actually traditionally. all our garbage and they've been doing that. for always. mind sniffing rats are put to work in former hotspots where learned mines are among the most deadly remnants of armed conflict they're often found years after was ended and serious injury isn't the only problem. imagine how it must feel to live with the knowledge that there's a landmine lurking somewhere near your home. when i was a close up field and to help make the problem of landmines a thing of the past. but it will be a full nine months before he becomes a real pro for now he simply spends his time with his family.

it's no coincidence that giant rats were chosen to sniff mines in the wild they're extraordinary sense of smell allows them to search for food buried deep underground it worked with land mines to the key is to train the a rats to associate the discovery of t.n.t. with food and that's not difficult because everyone knows how intelligent rats. the really hard part is making sure that the rat doesn't make any mistakes that could be fatal and not just for the rat. it's these regular rats that's clear from the way they eat these giant rats have special pouches in their cheeks to still food just like hamsters so this particular animal is on the cusp between being a rat in a house just perhaps that's why they're just a little bit cuter.

i guess i should add to another really great benefit of our species of rats is that there are really curious which lab rats are curious as well but they are very social in terms of they're really willing to work with people. sometimes will develop that relationship with you but i don't think they develop it quite as readily as our rats. meanwhile isaac has grown he's now four weeks old i'm training can begin like all children isaac schooling starts with the kindergarten. although it is a camera he hopes little rants to feel comfortable around people. to see if. he's the.

norm we teach the. truth. that's not. interacting with the care or is a vital part of the learning process it's important for isaac socialize. mind sniffing rats mustn't run away from all the bites people. when he grows up eyes are called way around a kilo and his body will reach thirty to forty centimeters in length just about as long as his tail. because they're so big grilled. their favorite local street food.

has started at school he spends his early weeks learning the basic rule that he means food. sound is used to reinforce the learned response when i can count as an empty container there's no sound. this one does contain t.n.t. and the click tells him that he can no claim i treat. well in general the handlers really let her do her thing they don't get involved or train influenced her in any way but some of the rats eating the rats has a different behavior just before they find. they have certain if behavior some of them like to clean themselves they like to groom themselves they're very clean. they don't like to get wet or maybe there's. some of them will walk around in circles some even stand up in the air.

and so the handler knows that she's found some think it just hasn't gotten to it yet indicated where it is. a rats remarkable sense of smell can detect the tiniest traces of t.n.t. . they can sense the explosive even when it's fifteen to twenty centimeters on the ground their noses of the not so secret weapon imagine if humans had similar abilities ok if you were in a pitch black room and somebody entered the house from. i would say. one kilometer away and it's pitch black and you can't hear anything you might be able to detect something changed but that's also very hard for me to say because i really as a scientist i need evidence to support such a claim and i don't have. isaac and his

sister at the gym they can give their paws a good workout sharpen their teeth. but enjoy a sense of freedom. looks as though isaac's trying to set out on his first trip. nice try. a brief chase. a few a breath so fresh. and he soon back in the fold. they know what to expect from. he learned most you have to

report. don't they don't. so i remember very were the words. and that's what we are doing. for about a week these students are only fed the food supply given the streaks during training mostly a staple diet of but no nose and not. just. during the weekend so little joy it's a good. when a veritable feast albert prepares a mixture of peanuts and dried fish this calorie cocktail is great for their bones do you think. you want.

them to it's no feast without dessert. this is for. you. this is your food or. in the wild giant rats live in small underground colonies. they're quite independent within the colony they live in their own burrows and tend not to share food with neighbors. females can choose their own mating partners but the colonies are not matter. they're ruled by a group that works a little like a parliament with both male and female members.

and. it's a big day for isaac. is about to move on to high school. just like every graduate to be he gets his own personal transport. now i can start his field training. giant pouched rats are nocturnal they sleep by day but have. night lives. carers try to adjust to the rats biorhythms they set out at five thirty in the morning so a field training session can start at six. bits

for moments like this that isaac has been trained is not alone by the sound of the engine. for a world cup twenty eight team coverage we've signed one of the greatest goalkeepers of all time but there was one more question and by the way was going to be our coach. guys i know you are nervous he's a huge star in the us and the huge amount of pressure camera you have to the center of the digital with you and we'll show you a great big bridge to get you out of the rock at the back nobody gets past you we

need you to get down going left go. alone. and i'm really happy to join the fall of two thousand and three in the world cup in russia meet the special one. needs to just read the review the aussie team's latest edition to make up a bigger. book. the far right in britain isn't just on the march it's taking violent mothers action by young white men. yet when i did you know i saw these organizations which are usually split into which we form which type different names how do you view that look. in. the complex web of british fashion.

my conclusion piece had to be meat to train to drink this. again. and now you'd like it the only other one. reason three number one. so it's not the right man who is telling them. the blank you have to do this in this in this new manner. we have to. sort it did is material enough for the old to be used to train the young.

eyes a groom a coma while he's in for his class to start. in the trust between trainer and rat run steve. so. he lets isaac out of the cage just without even bothering to follow. they have to concentrate them on the be a viewer of that they they have to do and make an interpretation of for the writ is doing. we did you come to d.c. when you were telling about your. adventures during.

isaac is now demonstrating model behavior for a my non-thinking rat. he sniffs diligently at the end. is in no hurry. this is the result of several months of training. it looks as though isaac might offend some t.n.t. . he tries to rid his nose of all extraneous sent. me thinks he senses something but needs to reset his smelling operators to be sure . this is the spot. you. know all the trainer can send his signal.

it's like watching two old friends getting together. at first but for him performing perfect i mean she was not running she was walking. she sniffed everywhere. she. liked records. to steve to t.n.t. the closer didn't work. there's a certain moment she wasn't sure about. the presence of t.n.t. .

isaac seems to have passed with flying colors. and now it's time to evaluate his loyalty. no one wants to chase a runaway red across a life minefield that would be deadly that's why it's important that the raps follow their handlers voluntarily without a leash. isaac is displaying textbook behavior as this training is over. now it's time for the real world to begin. traveling to see amrit in cambodia.

this is home to one of the ancient architectural wonders of the world. and caught a fact. millions of tourists travel here to take their best selfies tourism is one of cambodia's main sources of revenue. but there are still landmines left over from the civil war and they are seriously hampering any further growth and tourism to say nothing of the danger to life.

when it comes to square miles of minefields cambodia is second only to afghanistan . the number of injuries caused by landmines is the highest in the world now though the situation is changing for the better in the popular tourist resorts mines can only be seen in museums but there are still many dangerous areas in the country. isaac is here to help with mine clearance. new instructor applies some screen to his skin. because giant rats and nocturnal creatures their skin isn't the custom to high levels of u.v. if they were left unprotected and run the risk of developing skin cancer. ears and tails of the most delicate spots. we didn't see them doing this in africa because the training center is high in the mountains in the town of

ma to go to. at this time of year it's much cooler there than here in cambodia. if we take a closer look at the probables it's raining but isaac still has some screen applied . the sun might come out once the team stops working. this is no drill. team domes protective vests and helmets. no one knows exactly health protection the game would offer. they're off to work. it's not a hundred. but if we can talk in the next question it's not bad but these are.

international rules that you have to you. know. if if something exploded. in the north being a scottish and down to something explored at least to a point that they don't want an office rather than having nothing. just as we make our way to the minefield it rains again. if we do rains and then. it's only. march. we think that there is not another taking i mean is is going on is not easy for the . twenty that's why when drains a lot then we don't know what. it doesn't look as though we'll get to see ice a connection arrange getting every. couple

. see feel. pretty good. very good. there. are people. one more try. it's not quite clear if the rain will get in the way again or not. the mind to take is out in the field after all. isaac is investigating the ground.

nothing so far. suddenly he starts to wash his face. this means he's identified a suspicious scent. the disposal experts approaches. he has spent something. he seems to be really quite relaxed so perhaps it's not

a mine off to rule. is the mind that's not mine it's. made in china. i thought. mom didn't get. the. will finds a carefully marked on the. cleared areas highlighted in yellow for. the disposal team has a light breakfast after work everyone gets a banana. and they all seem to enjoy it.

has come a long way for this moment of triumph and now it's time for a rest. of the real heroes glory true heroes need to rest to build up this strength for their future endeavors. another round of cambodia's mine clearance campaign has come to an end the field engineers have a chance to relax the young men take a leaf out of the judge's book then night life is almost as exciting as the rats.

into it. this story of a landmine and. that's all there is to it. first in. the recent months of my.

friends and foes alike. i. thought thank you. thank you. thank you. thank you. for. a long with. terror at.

the terrorists killed in the. news. from the u.k. . and the. homeless people.
