it goes all the way back to the roman empire focusing on the past present and future of jewish culture and church. they're watching the news up next our reporter series with a look at russia russia in the taiga stay tuned for that i'm a spicer thanks for watching. what secrets lie behind us was. discover new adventures in 360 degree. and explore fascinating world heritage sites. w world heritage 368 get the patch now. find against the coronavirus pandemic. has the rate of infection been developing. what measures are being taken.

what does the latest research say. information and context. the coronavirus of data the code of special monday to friday on g.w. . each of us has arrived to pick up the locals. the train driver brings life to the taiga we are united because i did for the old grannies their villages are dying ours. is of it takes him to the village of sika yeah i hung gals in all them russia.

over i used to be a village. best bud loved driving these grannies arrived he always bring me gifts and hug me saying patrol bitch you're still alive and i see it but you're not getting rid of me that easily. and when you come back next year. i'll be here for you if you're good what's that but good at. the old days a locomotive pulls a what in trying to cop a long 31 kilometers off nowadays truck through the expanses out that russian type that. this is the wilds of paris for travis who men whom everyone here affectionately calls petrov it. he tries to solder him back on mondays and fridays

and then the went to he lives a fire in the stove before the passengers climb aboard. the trip takes $1.00 to $3.00 alice depending on how much snow is on the tracks it's not going to help when i drive a little over a 1000 passengers a year you know i didn't have it in summertime is mostly visitors. but in the winter time a lot less people take the train your $30.00 to $48.00 most per month for the us we should do that your leg short of the getting sick. i'm starting with stu. i should use birch bark but jesselyn works to keep the fire going faster. well to use the door seen as a warm up. it would keep warm. today petrovich is coming right on time at 8 am.

the village is looking forward to his arrival. here and i guess all our hopes have been the slow train and if it breaks down why be stuck here forever we are a car for destroying us all we have without it would have to walk 40 kilometers and there's nothing but old people here. this is just over here 35 this area dotted with a few dilapidated cabins used to be teeming with life. in the soviet era so it was an important part for the lumber industry when millions of cubic meters of timber what cut down and shipped off. the last lumber mills closed their doors in the year 2000. what remained was a heap of derelict equipments that patrol which used to organize a working passenger service it's punctual and reliable like the tropics himself and the locals love them for it. yet because wherever i go i'm

a guest of honor. the grannies here have no farhood that i magine live in the forest with. no one looked after that you did because they have history of the just because you need them to run come on and i don't know. but it's not for free. play ladies and i get this 100 dollars great if this old man or money bags where you comfortable virtue of your you'll hear it in my state good. yes. they head into after the closest not just settlement on the only one far and wide with a school and a few shops. to be young people but now they're all in their villages are dying out cheers and i feel the joke that's why i think what

we're still going to make any money from the us would be you are right that little bit if one you a 20 year project that they don't want to see new places. where else would they go . they keep going back to the days that we ride them back sometimes to go to the hospital and see that that's it we have everything else he brings us bread and groceries you. find that it used to be a lot of childhood here with all the cars the trains but what triggered his sleezy he says all that's left now is us he says and i would just like they said that he. was very mantic as described for the tiger my scene does assessing risk for the passengers despite petrovic his technical skills. sometimes the train just tips over christianity or not yet the friendly started as a few years ago which it was almost every day looking for

a different get to go once the train went belly up at midnight here to show 1st a car to 2 over and then looking motored with it through what he said about that much just wondering what do you fly out of the car. that you did you go to the next thing i knew. you were lying on her back it's pretty sure the tracks are worn down after tearing so many millions of cubic metres of luge they're totally ruined it's not just the trucks that are broken but the order and the social structures that once existed here. in this village most of the male residents have tend to alcohol. if you. go on and live here because we're also most supposed to live i'm retired. you can take.

them all right you know we're drinking wine i do you do some you know that you were right it's not really what we're not going. to do it would be what else is there to do here besides drink and drive and. that leisure activity can be disastrous as we will find out just a few hours later. in the meantime gets another vehicle ready to go and motorized or easy and all speed. if those days a locomotive broke down this light rail car is all you would have to get from saigon to have new guy on the same track all 31 kilometers of it. but this time with no woodstove. in the summer

picture average takes tourists for rides on the tracey and. in russia there are numerous societies dedicated to this exotic means of transport. the town of new at the other end of the route is where british rubbish calls home. he lives in 1960 settlements built for the timber industry. in 2010 around a 1000 people lived here but after the lumber mill closed in 2030 many more moved away. now there's not even a doctor just. a few shops and a little school. most presidents lost their way and some have 10 children. unemployment turning people into alcoholics. yet you get angry at the rest of the world and feel unhappy cheated. but there is work to be had they just don't want it

. to disguise this afternoon they were so drunk they burned their in the room real car this evening when i got a call from the emergency services to. the people there we were on the move and then bam he fell into the ditch. will be filled. petrovich has to lend a hand. in the middle of the night he has to get the right trail car and it's intoxicated crew out of this now and drive them to have a new guy for repairs and to sober up. everything was burnt in the truck at the electric system was busted this was a 1st in 6 years well after midnight the rescue mission is over. and over very long day and now he lights up the stove once we get that birch bark

burning in the down nice and interesting. washout and that's. everything if it had a mishap maint. here's the jam. for the most taking you so long valentina is petrovich his wife who you'll never see we also get pickles and fruit preserves paris petrovich and valentino have been living in harmony for 40 years. to like the. no my wife makes me the happiest man in the world to her i wish everyone could be just happy. but i also dream of traveling with her. i'm 65 now i've only travelled once to my brother's funeral no where else just work work work work work or work or travel it's me just what to live. think there's always been passed

away then and she as long as i've not have always the 14 years of age of books all of it i always have to be doing something i need to do they call it adrenaline. if i just sit around for several days i go crazy. even a month working. at the i mean. everyone needs this much energy like this in the letter. yet you have a day and night you know and i'll come get a print don't worry yes just like you plan the bread at 4 am. we'll be bringing them to the people inside at this point they can't imagine life without the trumpet or even death for that matter.

you could be but this is what it's going to do if one of the grannies called me and said the truth it should be used to limit your rights please don't stop as long as i'm alive but you gotta say when i die one day i'd like you to be symmetry in saigon my husband and family are very good you need help and advance the please don't stop it you just give me a go i said oh are you crazy but you know just stay alive yeah you're good you know well type the 3rd the snow day the month later today and i granted her her last wish because it's a get into that and show you just the love sick. child which doesn't want to abandon his elderly possum just so he plans to keep his tiger express running effect on my yes' and then it will land.

is there life on mars. the american space probe rover has set out to answer this question. just landed on the red planet but it's not only on. the teams competing with 2 other missions. everything you need to know about this think tank you are a race between explorers fawns mars are rooted. next on t.w. . check him takes this special trip. to do is show it's not just the city trip but also a journey through jewish history prior wars and mines are considered the cream of jerky judaism. jewish life has shaped these 3 cities for more than 900 years and i want to know what remains of it. 30 minutes w.

. is for everyone is a very different from primates you know. ridiculous the size of you. is quite. sex how to dance in books you get smarter for free books on. the final preparations ahead of last year's launch the hope probe is now over to mass the aim of the united arab emirates mission is to examine the planet's atmosphere and climate. the chinese t. and when one mission has the same goal the unmanned spacecraft has also reached the orbit of mars in a few weeks it is set to deploy a rover to investigate its surface. the u.s. is also up there with nasa is perseverance rover. the red planet has been

a goal of space programs for decades. the race to mars and more coming up on this edition of tomorrow today the science show on d w. almost 60 years ago mariner 4 was the 1st space probe to perform a successful flyby of mas it sent back images that showed a crazy popped moon like planets later viking probe sent the 1st detailed pictures of its surface including one that showed something that resembled a human face. in the late 1990 s. pathfinder mission brought the 1st robotic rover to mars. the europeans are also drawn to mars the european space agency suffered a setback with the losses. the mars lander skep it early in 2016 but the mars express remains in orbit 17 years later.

our intriguing neighbor is bleak barren and inhospitable but a long time ago it may have supported life it's seen dramatic changes in climate evidence of that can be found on its surface since 2004 mars express has been studying the red planet with a range of complex instruments it was the european space agency's 1st planetary mission. it's an unbelievable technological achievement or. 2 born to build a spacecraft that can keep working for nearly 20 years in a very tough environment with high levels of radiation without maintenance or anything else. to feel or think it's worked faultlessly to this day that's very very good. this special camera is the most important instrument on mars express it was developed by

a man. with the camera produces detailed images it has mapped the entire surface of the planet for the 1st time in 3 dimensional color images. the models of the terrain provide new insights into the geological development of mas and the history of its climate. shortly after entering mars his orbit the probe found frozen water on the planet a sensational discovery as the presence of water indicates the possibility of life and it provided evidence that huge amounts of water once flowed on mass. you know how high the mountains are goes and how deep the valley gets it coming in from that we can work out how much water was in which location and how long it was there. so let's keep trying to establish where that was for one's life on mars and also in determining whether we might be able to do something there in the future.

or to contract us to move on from. the river that once meandered along is comparable to the river rhine in germany it would have transported the same amount of water through the valley 30025000 cubic metres a 2nd. and on the planet's largest volcano mars express discovered signs of fresh larva some 2000000 years old that means there could still be warm areas on the ground where my crepes might be able to live. that's a huge near the equator the orbiter found evidence of past places another spectacular discovery. this. was some stage ice float into an impact crater there's a 2nd impact crater beneath the 1st one of the 1st overflowed and the ice merge into the 2nd grader before i was totally amazed i have to say i grew up in the

mountains i almost felt at home looking at the images in the 1st 2 hours of. the ice shows that the tilt of mars is axis has changed substantially over time causing the equator to move toward the poles and vice versa so i say that's now near the equator was once of the poles the change occurred over millions of years during that time rivers came and went but evidence of their existence can still be seen today. mars express is also equipped with radar that penetrates the surface of the planet to a depth of 5 kilometers. that allows it to see what happened to the huge amount of liquid water that was once on ma's. radar measurements show the southern polar icecap is the size of europe the ice here would be sufficient to cover the entire planet with

a layer of water 11 meters deep. and in 2018 the orbiters radar found the most important prerequisite for life liquid water located in underground lakes. it's the white lebanese the strait reflection line on this radar image. of mars express the trauma to also made an exciting discovery it found may thing in mars is atmosphere. now says mars rover also detected the gas on the ground at the same time and in the same region. this is current is not really sure methane is a crazy kind of molecule it disintegrates with ultraviolet radiation so that means if it really is in the atmosphere and it can't be more than a 1000 years old. it's very likely that the methane came from below the surface

but how did it get there could it come from microbes living in underground knishes that produce methane like on earth in the permafrost. or was. released through geological processes caused by the weathering of volcanic rock these are questions mars express can thompson. as though the trace gas orbiter was launched it reached mars in october 26th. then spent a year and a half orbiting the red planet drawing increasingly closer until it was ready to begin taking readings. the orbiter is designed to detect me thing and other trace gases in the martian atmosphere twice per orbit at local sunrise and sunset it can also study the different layers of the atmosphere its instruments are so sensitive that it can pick up just 15 methane molecules out of a trillion molecules in the atmosphere. a camera on board the orbiter is designed

to show where the me think could have come from. it's already sent back some amazing images but so far the trace gas orbiter has not found anything. you want the mission needs to continue for quite a long time to get meaningful readers when it's the most demanding we're talking about levels so low they may only just be detectable that on one's going to hard to fix your wants currents. next year should see the launch of a european russian mars rover the rosalind franklin it will be able to drill 2 meters into the ground to search for complex organic molecules traces of microbes might have survived in the ground protected from the space radiation that bears down constantly on mars that radiation would quickly annihilate any signs of life on the surface.

you can find more on. mars on our website d.w. dot com slash science 'd and on twitter. humans have long dreamt about colonizing mars. we'll ask you whether you can imagine humans sailing on mars in the future. magnus slim lay in drug on writes yes we should and it would be a great relief for our planet. that that publicity disagree no he writes it's enough that we are destroying our own planet as we don't have to destroy mars as well. as he raises a few issues to consider writing i think that the mass of the extreme heart and cold temperatures will have to be taken into account and who will be president of

all being there. on twitter we asked you what mistakes we should avoid if we settle miles. everything that is causing us trouble here on earth writes allies approve. she fears however that won't work long term as soon as the pioneering spirit evaporates groups will form that will try to do their own thing. i'd y.t.d. tweets that we should avoid dividing mars up into areas of national interest as we've done in the antarctic thanks for all your comments speaking of the antarctic . it is a bit like mars in that it is attracts a lot of researches though with a boom in tourism it's not something of its mystery. but the 1st research is there is a breaking new ground on the terra nova expedition the british saw to be the 1st to

reach the south pole but that on a whim to norwegian role the ammo. and this famous from expedition. today's scientists still have their side 6 on the continent. reema say discussing honest molina had a question about that. why is the antarctic so important for research more than a century after the race to the south pole researchers are still passionate about this remote desert of ice scientists from around the world are still trying to uncover the secrets of the continental ice cap they live and work in some 80 research stations in some cases all year round. far away from human influence antarctica its proper name offers a unique laboratory to investigate the earth's history preserved deep in its layers of untouched ice. and because the ecosystem here is so sensitive climate changes

and environmental impacts leave a precise record besides i samples from deep below the surface scientists also collect data high in the sky where radio transmitters on weather balloons record temperature humidity and wind. and what about them penguins are a living barometer of how changing food resources and global warming affect the ecosystem. scientists are worried the emperor penguins will suffer enormously under global warming they need the ice as a platform from which to dive and hunt for food and they also need the coastal ice shelf to stay frozen until january for nesting bats when their fledglings lose their down coats and can begin to go hunting in the icy waters themselves. if the ice keeps on melting their outlook is graham.

no other place on earth is warming as fast as the emperor penguins home the peninsula on the continents west coast so researching and. understanding climate change impacts on and arctica is of critical importance for the continent and the world. if outlet is read write latin if you do you have a science question you'd like us to answer some of them as a video text or voicemail if we featured on the show you look at and little surprise from us as a thank you will find the address at the end of the show come on just ask. a. south american monk parakeets in the spanish capital madrid. can. read swamp crayfish and sensual but then invasive species are threatening native ecosystems under the top 10 is the european standing which has spread to north america parts of africa and new zealand words endangering native birdlife. the

asian cup has spread to europe and north america due to the live fish trade and sport fishing. the cane toad has mightily to australia it was introduced to fight pests but now it's endangering native species . the water hyacinth is spreading worldwide the problem is that it deprives other underwater balance of some lines and oxygen. and the several muscle is also on the move the next report is about a question in vegas and takes us to northern germany and. the sun sets on the north sea island of zoot setting the scene for an intriguing nighttime spectacle a scoop neck trail through the water captures some interesting creatures repitch just little things that aren't native to the region the sparkling blue luminescence

is the calling card of nemi abscess the warty comb jellyfish they probably arrived in chips palace. tanks. the geo more research vessel aims to find out just how far they've spread in the baltic sea how rapidly they're reproducing and their effect on marine ecology. expedition leader cornu ya is a jellyfish expert the data that's been collected still has to be evaluated but the initial impression his worrying trend is a lot since we have a coward the entire german baltics ecosystem taking samples from a variety of which show that the already coming jellyfish can be found everywhere looking qualified nestlé in differing sizes and density includes that we have a big problem with them the op says especially here in heel and the southwestern baltic in the absence of. the woody comb jellyfish is native to the east coast of

the us ships presumably carry them as stowaways to the black sea in the 1980s from there they've spread to the caspian sea the mediterranean and your northern europe . the creatures also called sea wall which due to their shape may look in conspicuous but they pose a huge challenge cornell yeah spurs wants to know if the ecosystem here is holding up that's called limits nish time is not the problem with non-native species is that they don't belong. there only labeled invasive if they start to change the ecosystem. because esteem and the problem with the walnuts is that they're extremely efficient predators and i don't i wish they generated mucus that invisible to most other organisms. their prey only notice the danger when it's too late and they're caught up in a sea wall that sticky sells. them in the ups us and give bigger jellyfish can filter 450 liters of water a day. and they consume 80 to 90 percent of the living creatures the plankton

increase in that water. you just saw plankton of that christiane isn't. marine biologist coston riser is looking into the impact of non-native species on the water and sea mudflats of the north sea. he immediately sponsor if you like the soft shell clams which disappeared here back in the ice age apparently the vikings then carried them back from north america as a fresh food supply. other species from even further away are also trying to establish themselves here. on this muscle you can see and they'd have barnacle go and this little volcano here the pocket guesses but next to it are 2 tiny stars that's those are australian barnacles. to shake even managed to come this far. match because the hypothesis is that they arrived in

plymouth on british seaplanes dolls and they've spread throughout the north sea in only a few decades of pride a very special recent arrival is the pacific oyster native oysters became extinct on the soapbox last year due to overfishing last century in the 1980 s. there asian relative proved a robust replacement for cultivation now it's pretty liberal wing wilds across the flats thanks in part to ocean warming. to find me a home cook for reading this oyster prefers 18 degrees celsius or warmer him average summer temperature here in ca by september 12th or does it back in the 1990 s. that wasn't as common it only happened once every few years here and fun to begin with they bred relatively slowly but with global warming since 2000 every summer has been warm enough for them to breed. it became a kind of power

a device for the oyster and it bred fast so you see it's more common here now than in its native yellow sea or in japanese waters on tiffany's. rises says the system adapts crabs have a stablished themselves here now a threat mostly to young more stars but the warty comb jellyfish still has no enemies kornelia ya spurs wants to see if some types of fish might take a liking to it or perhaps the parasitic amphipod the high period galba which nibbles away other species reproductive organs the traditional kind of feel they have no natural predators in the central baltic at the edge of where the nanny outfits of expanded somehow we have seen that caught fish to eat them ted thank you state researchers have no real idea what species might prey on these jellyfish and control their population that's a new field of research and what i'll be investigating in the coming years. at

least research is also yielding some new insights controversial r.v. for example seem to be able to escape the warty comb jellyfish just clutches but many open questions remain what is the purpose of the jellyfish is fascinating light show and what impact with their presence have on the ecosystems of the north and baltic sea. and that is being remodeled in the ocean. a home for plants and animals in the past a lot of good and was drained to extract. or to create the land but that also released gases that are harmful to the environment. many moons are now being restored so they can once again after carbon sinks but what about the impact on phony. eggs small ponies and water buffalo

graze peacefully in an area of south east germany known as the swabian door now morse. for decades this moisture friend was drained and used for farming during that time the pizza oil gave off huge amounts of greenhouse gases since it's been reflooded the levels of carbon escaping from here have dropped significantly but can a farmer still make a profit from this fan and agricultural engineer i mean a schumann works for a foundation committed to preserving and developing the habitat she's working with farmers to test out new ways of using the land. so in the land of farmers were initially opposed to the reflooding 50 years ago they had to drain it all so they didn't see why that should be reversed. but it's to reduce carbon emissions. by giving it farmers the chance to keep livestock on the land we're offering them alternative sources of income and. for my christan my agreed to work

with the foundation in 2015 he builds up a herd of motor buffalo for the risk paid off the marshland is ideal terrain for the animals with their why. cattle probably wouldn't cope with the story of the water buffalo have no problem at all they're happy to eat the grass and their meat sells well there is no comparison with cattle for. my i get subsidies for his life start from the local. money by cutting the grass on land not used for grazing as another nearby fan scientists are overseeing the reflooding they're testing how different grasses affect carbon levels. we're looking at greenhouse gases it's an automated system that measures trace gas for us you can see the frames around with plants inside. comes over the top and measure the gas we're interested in or dropped inside the

frame it may be c o 2. so we can measure the emissions for a specific plant at a specific water level. just the water level mustn't be too high $10.00 to $15.00 centimeters below the surface seems to be ideal for the least amount of carbon escape into the atmosphere. the scientists are also testing to see which marsh and wetland plants could be most profitable for the farmers. experimenting with growing grass. on his farm he breeds alpacas normally he feeds them hay but he's going to try them on freshly cut said. i'm intrigued to know whether they'll lead. it in how well bill take to it we'll

see. it's the 1st time this said field is being caught behind his colleague christian maya has also saying stages they've been very well on the damn ground on the mowing is going smoothly. next to it conventional summer crops grow on drained and this land emits 20 tons more c o 2 pac taf the. aim is to see the difference what we can do with the soldiers and how much profit we lose to see what the future could look like. as yet the farmers don't know what they can earn from the said yes. but the reeds have many potential uses. cause it's unpleasant grass is the basic fodder for our livestock so of course we'll try that it could be fodder for the bio gas plants to generate energy would have been or we could create pellets for thermal warming or

insulation blocks like this one which is made of gold rush which has excellent thermal properties that's toilette how much a lot. but all these options 1st have to be tested. and culls is intrigued to know whether his alpacas will eat the fresh said which is quite tough. but. that's about it so that was clear 0 interest. in one more try. then decided if they don't want to fresh i assume know it it once it's dried as of the morning when it well this stuff dries well to top it off i'm optimistic about the whole project optimistic from positive in. the trials and you to end in 2022 they stand to benefit both the farmers and the

land as well as the climate. that's all for now thanks for joining us on tomorrow and today. will be back next week with more fascinating stories from the world of science and technology until then but by.
