food delivery firm deliveroo says it is quitting australia because of tough economic conditions. the country's government has been putting pressure on companies to improve gig workers' conditions. animal crossing's first e—cycling centre! intel has created a land on the game, animal crossing, to help educate us on how to recycle old tech. the firm says electronic waste is rising three times faster than the world's population. the steam train — first built in 180a, it made rail travel cheap and suddenly everything seemed much closer to home. industry rolled on, and by the 1960s electric and diesel trains had replaced steam. today, around the world,

most high—speed trains are powered by electricity. at the bo�*ness and kinneil railway, engineers have also moved on from the past and into technologies of the future, where they are working towards cleaner rail travel. this is a little train that could be powered by hydrogen. the train itself is not new. instead, this is where old technology meets new and a test of where hydrogen power might be a viable option on our railways. the technology beneath my feet is relatively new for the railway but one of the interesting things about this project is that this train is actually quite old, built in 1979. it has been retrofitted to run on hydrogen. so, what was a class 314 headed for the scrapheap is now a class 614 hydrogen—powered train. the hydrogen is stored in tanks
11:47 pm
underneath the carriages along with the hydrogen fuel cell which converts the hydrogen back to electricity which powers the train. all that is emitted is steam and water. the hydrogen needed to power the train is made on site. electricity from renewable sources is used to split water, creating hydrogen. that is then compressed, compressed again, and then stored ready for refuelling the train. but if most of the uk rail network is electrified, what part will hydrogen play? some commentators say that hydrogen is actually a distraction and what we should be focusing on is fully electrifying our railway lines. if you have a route where you cannot do overhead electrification and the route is too long or there is not time to charge, then the hydrogen train fills that gap. you can get a range approaching diesel, you can refuel quickly and you can transport
11:48 pm
hydrogen multiple ways. so the hydrogen train fulfils some operational requirements you cannot meet with other approaches. it is not the only area of transport looking to use this element. aberdeen is a city built on oil and gas, but it is now home to the first hydrogen powered double—decker buses in the world. how does this work? what we have, watch your head, in total more than 25 kilograms of hydrogen. that will pump the hydrogen to the fuel cell here, it mixes with fresh air and then in the process, we end up getting electricity that comes out. this issent into a battery and from there, go to the battery controllerjust the same as an electric vehicle. to get these clean and green buses up and running, hydrogen refuelling stations were set up around aberdeen. it's just like filling the bus with diesel. instead the pumps are
11:49 pm
stocked with hydrogen. when do you think diesel is consigned to the garages of history and the majority of your fleet are running on renewable products? five to ten years, definitely. certainly, as a group, we will not buy any diesel buses in the future, it will be electric or gas or hydrogen buses. thank you, driver. it is notjust buses looking to hydrogen as a fuel of the future. this is the first of its kind, zero emission hydrogen—electric hgv which runs off renewable electricity and like the hydrogen buses, water is its only waste. in the hgv sector, we're seeing hydrogen is the only technology that is able to give the long range, the heavy payloads and quick refuelling time. if you think about what we currently do, which is, we drive around with flammable liquid in our cars
11:50 pm
with small explosions going on around our knees and a tank of flammable liquid behind us, hydrogen is much safer because these tanks are very solid, they have triple layer carbon fibre reinforced. so there is a place for hydrogen in transport. if we continue at our current rate, scientists estimate our fossil fuels will be burned out by 2060. we know the way we travel must change and we can no longer rely on nonrenewable energy sources to fuel our way of life. with hydrogen and electric hybrids set to be the future, clean solutions are here to stay. that was laura. in my coat! i noticed that, actually. talking of clothing, we have spoken in the past about problems with fast fashion. these are clothes that are so cheap that they kind of feel disposable. we have seen new ways of being able to recycle fabric but this week
11:51 pm
we are taking a look at a problem that i for one didn't even know existed. luckily, shiona mccallum has found the solution. we know that fashion hurts the earth. more than 92 million tonnes of textile waste is created every year. recycling is possible but chemical dyes and prints often prevent this. if you are anything like me and buy merchandise every time you go to a gig, you may have loads of band t—shirts but sometimes your tastes do change and you are stuck with these logos forever. one team here in gothenburg are trying to change that. the idea is that they print the t—shirts, strip them back and reprint them so they can be used again, again and again. the start—up is not changing traditional fabric inks. instead, it has developed an invisible layer that goes onto the fabric first.
11:52 pm
made from entirely friendly ingredients. this can result allowing the top design to be removed. what is the tech that goes into creating this recipe? it is all about a balance and trying to find the sweet spot for both the functionality but as well as stability. we look at the charge of the component, we study the films that recreate through a microscope as well as the textiles that we are applying the print to. is there any waste product here? we create the volume for what we are trying. the mix is applied at an industrial partner where it is easily brought into the screen printing process. hello, welcome to sweden and gothenburg! i think you have a surprise in store for me? yes, i do.
11:53 pm
today we are going to print a click band t—shirt. i am excited to see how it works. let's get started. the final result is here. i love it. how could i ever want this to be removed? use it as long as possible and then remove it. just for you guys, i will take this t—shirt back to the lab and see if the technology can completely remove the logo. right now, this means putting the t—shirt in a bowl with the chemical. it is then treated at high—temperatures and left for about an hour. afterwards, there is a secret technique in getting the print to physically come off and it should get better as the recipe and the process is fine tuned. we have some traces left.
11:54 pm
the band logo has gone and i can only see a few speckles of pink. a pretty good job. i reckon you could print on top of that and you would not notice. this would be good for recycling? definitely good for recycling. which is the main point so it won't end up in landfill along with traditionally inked up garments. another test processed more precisely without the delays of us messing about and filming has come up even cleaner. you can get it more less completely off? we are 100% sure of that. wearers are not expected to strip their own t shirts at home. the t—shirt companies use our technology, people get to get the textile and then wwe take it back. with several large european partners already developing their own garments, there is clearly an appetite for closing this circle. with more than 100 million
11:55 pm
items made each year, it has never been more important to make all textiles recyclable. i did keep one of these just for my next gig, though. and that's it for this look at some of the latest innovations that are hoping to tackle climate change. it will take much more than those to make a dent on rising global temperatures but when we see something that we think is promising, we will make sure you see it as well. thanks for watching, we will see you soon. bye— bye. hello there. the start of this weekend has been unsettled, thanks to low pressure, wet, windy, followed by blustery showers and sunny spells. part two of the weekend also unsettled with the same
11:56 pm
area of low pressure close by, it's going to stay pretty windy with plenty of showers rattling in from the south—west. here it is, this deep low, the centre sitting just the north of scotland on sunday, some fairly strong winds close to it's centre over the north and west of scotland. elsewhere, plenty of isobars so it is going to be another blustery day, maybe not quite as windy across inland areas that we had on saturday but lots of showers around, forming bands moving from west to east, some of them heavy with some hail, some thunder mixed in, very windy across the north and west of scotland, gusts of 60, 70 miles an hour. tending to ease down a little bit later in the day but it's going to be a blustery day wherever you are. probably the best of the brighter and sunnier moments will be towards eastern scotland, eastern england. but a cooler day to come for all, temperatures of six to nine degrees, for most in single digits. sunday night, little change, it stays blustery, further bands of showers moving from west to east. wintry elements of them over the hills of scotland and we will see that throughout the day on sunday, maybe even down to lower levels
11:57 pm
for the early part of monday. it will turn a little bit colder across the north and the west. as that area of low pressure pulls away on monday, it allows this brief ridge of high pressure to nose in. that will tend to settle things down, kill off the showers across some southern and western areas, but they will continue to rattle into parts of scotland, maybe north—west england again, wintry elements over the hills. but an increasing chance of drier and brighter weather in the south on monday, thanks to that ridge of high pressure, and we could be up to ten or 11 degrees, still quite chilly further north. that brief ridge won't last long, it will clear away during monday night. into tuesday, it is back to square one, wet and windy conditions with this next area of low pressure moving in. so some of that rain will be quite heavy as it splashes its weight northwards and eastwards, snow on its leading edge as it bumps into the colder air across scotland but it will revert back to rain as very much milder air pumps up from the south. and we are looking at highs of 13 or 14 degrees across southern britain. and it will be initially cold at the start of the day

this is bbc news with the latest headlines for viewers in the uk and around the world. i'm lukwesa burak. despite promises of an orthodox christmas ceasefire, russian missiles continue to strike eastern ukraine. there is still a heavy shelling coming down from the russian side. ukraine is holding onto the city, and it's not going to want to let go anytime soon. crisis talks for the uk's national health service — the prime minister urges health leaders from across england to take �*bold and radical action�*. that was easy, huh? at the 15th attempt, kevin mccarthy is elected us house speaker — after making concessions to the right of the republican party.
