it's a remote destination, far away from wars, crisis, terrorism, disasters. so what could be safer? two—wheelers on the country's roads. and this one is powered by gas — but can hardened bikers be converted 7 lurking in the water. and they were freezing! nick: one of the seven

wonders of the world, structure on the planet. threat of extinction. this is the world's largest cryopreservation they have had a pause button pressed on their

biological clock. so these cells are frozen in liquid nitrogen, is —196 celsius. wow! i won't pull it out because we don't want to warm safe inside that tank there. then, and keep them safe. to ensure that genetic diversity is not lost, and that genetic diversity can be introduced into populations. roughly half the samples survive. this particular sample has a large number of sperm moving.

we can use it to monitor sperm quality over time. they've got around 4,000 vials. so this is a mini tank. it looks like a giant thermos flask. yeah, it is, it really is. when they're being shipped. wow. from the species of coral, the number of sperm in it viable, the sea country of the corals. and so that vial, there'll be about five vials

put inside that canister. and then that canister goes back inside the tank. set for travel. let's put it back. we're seeing corals not being able to withstand these higher temperatures, and so we're losing genetic diversity each summer. activities for those particular reefs. spawning, which is the mass event when coral release their eggs to be fertilised, only happens once per year. sperm during spawning. coral ivf is only part

of the preservation puzzle. which involves a trained expert hunched over a microscope - counting very tiny microscopic| corals one by one over a small while it takes an expert about an hour to counti one tile, it takes usi a couple of seconds. a couple of seconds! as fast as a human. even so, they've got their work cut out for them. we need to grow over- ten million corals per year. and so to do that, we need to have tens of thousands. of these coral tiles - being measured and counted just in pure counting time,

over $6 million per year. l as well as cash, it could save lab time by generating heat maps. that the corals are doing well. help save the reef? over to surviving for many more decades to come. _ data is lost, or if, years from now, the the search is on to find solutions that will stand

svalbard is an archipelago high above the arctic circle. we're about to head inside a former coal mine. it closed down three decades ago, and now it's home it's a remote destination, far away from wars, crisis, terrorism, disasters. and it's regulated by an international treaty. far away from everything, accepted by all the superpowers in the world. well, i guess we'll switch our lights on and head let's do that. temperatures are sub—zero. and behind these

doors is the vault. culture, history and technology for future generations. what sort of things are stored on that film? countries across the world. so it's a wide selection of cultural heritage, there are surveys of the taj mahal, old manuscripts from space, plus music, movies and paintings. this is a very

special container. and in this box is a copy of all the world's open source code — the building blocks of most of the world's software and websites that we use. it's incredibly important for humanity to secure the future of software. it's become so critical to our day—to—day lives. we're essentially building another wonder of the world and also how you'll actually be able to read them. it's dark, dry, and very chilly down here — that could last centuries. storing this information down here in the depths of a mine, how does that help preserve it? today, there is a lot of risks

to information and data. survives technology, obsolescence, time, and ageing. so, the data are stored on reels of piquilm, which is an information carrier that cannot be hacked — data cannot be deleted, data cannot be changed — and it's self—contained and self—descriptive. you have all the instructions future generations will need to have to really understand what it is and how we can use piql, and back at its norwegian offices, all those files are printed onto film.

we convert the sequence of the bits, which come in some ways, it's quite old—school technology — but that's the idea, and it's intended to be easily readable even far into the future. and we can decode the data just the same way a user but we will be reading data from the film. which inspired the arctic world archive. just behind those doors, a deposit ceremony is taking place right now, and there are individuals and

for many here, it's a significant moment. the highest point of the island is three metres, and they're l it was really humbling. it's really surreal. going down an arctic mine. today, no matter how uncertain the future.

nikhil: 250 million. horns toot that is the number of two—wheelers on india's roads, to the worsening air quality of its cities. but one company now claims it has a solution. that runs on compressed natural gas, or cng. in a cylinder, and is both cleaner and cheaper but mounting this tech on a two—wheeler has taken years of trial and error.

the motorcycle has very little space. a cng cylinder is big, it is heavy, and it is of a certain shape. so that has to be integrated and designed as to take care of that. that the customer will never be stranded, there is an auxiliary fuel tank which is right over here, bajaj claims using this fuel effectively halves the running

like riding any other bike. today is impossible. do you think evs will sort of fundamentally pose a threat to these cng bikes in the next few years? nothing has ended ever.

of actual manufacturing? it's a cascade of things that has to fall into place first. to meet that goal. long lines like these of cng—run tuk—tuks and taxis are a regular sight at india's gas stations. these infrastructure gaps will be critical. ha—ha—ha! 0h! with my feet in the waters of lake zurich?

oh, god! twice. in this lake comes from. blooming glaciers, don't it? they become numb and you don't feel it any more. something that would work well in swiss waters, in particular rivers. withstand strong currents. yes, just as aerial drones can hold their position in strong around it is rushing

past at three knots. and today i get to see the latest upgrade to its adjusts its motors to counter the turbulence. it's pretty nippy. it can travel at about four knots, and it has onboard cameras — but, because the water it also has sonar, which it uses to build up what's called a 3d—point cloud of the area. how are they looking — blue? actually, are they still there? time to take tethys for a dive... take me on an adventure. sure. show me the sights. as is common in robotics these

days, andrej is using what is this, a little fishing boat? nothing too crazy. it's pretty zippy. it goes pretty fast. years of my life nearly professionally. i can't keep up with this. you can believe that, can't you? well... honestly. autonomously and avoiding obstacles and mapping its own drones, it can't see gps satellites from underwater. so, our drone is able to map i and localise at the same time. so, when the drone sees like new fields that it - has never seen before,

it can generate a map. | it can recognise that it has been there, and then, - like, fuse all the - information together. it's a bit like the vacuum cleaner robot. it's more or less the samei thing, butjust underwater. visibility by using sonar, as well as normal cameras, plus the option to fit various grippers and tools, all areas that are hazardous even to the most highly—skilled human divers. is this fish? a lot of fish, yeah, exactly. wow!

and then, decide to work together to take their research further. who knows what discoveries await this little robot? there's a chair! a chair, yeah. there's a chair. i mean, it's for sure cosy. i'll tell you what, i often see the occasional wild shopping trolley in a lake, but i rarely see a chair. now, where did i leave my shoes? incredibly beautiful today, isn't it?

hello. we've got wet and windy weather on the way for sunday, so it's fair to say it's a weekend of two halves. through the afternoon. nantwich in cheshire. that's about six above average for the time of year. and at the moment we do have clear skies across so it's a frost—free start to the day. the wet and windy weather, then, that's on the way for sunday is all courtesy of this quite deep of the uk, but it's a low pressure that will bring two hazards. one — heavy rain, and across some of the western hills

that's enough to cause some localised flooding concerns. now, gusts could reach around 55—65mph through the irish sea, although conceivably somewhere like capel curig could get quite close to 80mph. 60—70mph gusts of wind into western scotland. the winds for these areas are strong enough to bring some localised disruption. and eastern england, we've got the wet weather working in through sunday afternoon. sunday night, well, the rain continues to push south clearing away from south—east england with blustery showers following to much of the uk, it will remain quite windy across the hebrides, down through the day. average for the time of year. we continue with those rather showery conditions into tuesday. the majority of the showers will be across the northwest

of the uk, and although it will continue to be quite average in london is about 9 celsius. will stay quite windy too. bye for now.
