following president tsai ing—wen�*s trip to the united states. now it's time for click. this week we've got plenty to whet your appetite. we're in singapore to test the future with a starter of pink gold, followed by your main course. this is my first ever taste of cultivated chicken. there is a special 50th birthday treat as we chat to the man who made the first mobile phone call. and for desert, an internet legend

tells us what it was like to be part of the twitter takeover. i really did get to see what was happening right in the thick of it. it's hot, it's bustling, it's intense. welcome to singapore. i've come to a citystate that is home to more than 5 million people and atjust 50 kilometres wide and less than 140k from the equator, this place feels like it in the centre of everything. east meets west here, nature meets future. this is a thriving financial hub that seems to be doing pretty well for itself.

when you think of singapore you might think of the tropical climate or all of the greenery, or even the pretty cool architecture. and everyone that i know that lives here, they say it's a pretty nice life. but this tiny island nation does face its challenges. land is a premium here and they need to import... well, pretty much everything. although it's brilliant to dip into the melting pot of different cuisines and cultures, it is a reminder that 90% of singapore's food is grown and farmed elsewhere. singapore is a very small country, so you can imagine we don't have the same amount of land to grow many of the crops or animals that we need to feed ourselves. particularly when we have seen how food supply chains have been stressed. whether it's because of climate change, geopolitical considerations or pandemics. but being so small has its advantages, too. singapore's government can make quick decisions, acting like a nimble start—up while bigger countries

pass legislation as fast as supertankers change course. and so it has become the first country to approve the sale of lab grown meat and it is trying to become a global hotspot for alternative protein products. we also alternative protein products. - also expect going forward many other locations in the world will encounter similar challenges as we do. singapore aspires to be that location when you technologies are developed, commercialised, scaled up into the region and globally to help other locations to address their owns food security issues. we think if we can be successful at that, that represents notjust an opportunity for us to address our own needs, but lead to address these large economic opportunities in terms of creating good jobs for people who live and work in singapore and for businesses to survive in serving the needs of the

guys have worked out how to do it. this is lactoferrin, it's been called pink gold. think because of the iron and gold because it is rare and expensive. but this company, turtle tree is finding a way of mass—producing it. not from cows, and knotty even from cow cells, no, they are fermenting it using yeast. the process is similar to a brewery. these are large fermentation tanks that will be culturing the cells and each of the cells acts like a little factory, singly producing active farrant. , ., , factory, singly producing active farrant. , . , ., , factory, singly producing active farrant. , , farrant. the yeast has been genetically _ farrant. the yeast has been genetically modified. - farrant. the yeast has been genetically modified. turtle i farrant. the yeast has been - genetically modified. turtle tree has taken the genes from cow dna which is responsible for making lactoferrin and transplanted them into the dna of yeast cells. find the right strain of yeast and brew

abundant enough to add to lots of products, like sport drinks and plant based milk like ot and almond milk. and all without the need for animals all the land for grazing and feeding them. now the company has cracked lactoferrin, it is starting to work on other proteins that are normally found in milk, which could be added to other things that are not milk. , , ., , not milk. there will be people, consumers _ not milk. there will be people, consumers for _ not milk. there will be people, consumers for whom _ not milk. there will be people, consumers for whom this - not milk. there will be people, i consumers for whom this sounds not milk. there will be people, - consumers for whom this sounds like a natural, what would you say to them? ., �* , ., a natural, what would you say to them? ., �*, ., _, them? even though it's not coming directly from _ them? even though it's not coming directly from cows _ them? even though it's not coming directly from cows milk, _ them? even though it's not coming directly from cows milk, it - them? even though it's not coming directly from cows milk, it is - directly from cows milk, it is exactly the same protein. what we are showing is that it is so similar and there is so much experience with cows milk derived lactoferrin, we are showing this structurally is the same and functionally is the same. so we are going for a regulatory process called generally recognised as safe, because it is already in the food system, we are already

consuming it. if the food system, we are already consuming it— the food system, we are already consuming it. if you want to make milk in the — consuming it. if you want to make milk in the lab, — consuming it. if you want to make milk in the lab, that _ consuming it. if you want to make milk in the lab, that is _ consuming it. if you want to make milk in the lab, that is a _ consuming it. if you want to make milk in the lab, that is a different| milk in the lab, that is a different process entirely. that would need animal cells themselves. something thatis animal cells themselves. something that is involved in the chicken that is waiting for me later in the programme. now, five decades ago an american engineer who made history ljy american engineer who made history by placing the very first mobile phone call on a busy street corner. and zoe has been chatting to marty cooper to find out more about that iconic moment. mobile phones, we love them. the un estimates that three quarters of the well�*s population owns a mobile phone and there are more mobiles than people in the united kingdom, according to the industry trade body. this man helped make it happen. marty cooper was an engineer at motorola. 3rd of april 1973 on a street corner in new york he made the first public mobile phone call to a competitor at a rival company.

i was demonstrating this cell phone and i took out my phone book and that gives you an idea of what primitive times these were, and i called my counterpart in the bell system phone book. i dialled his number and amazingly he answered. i said john, i am calling you from a phone booth, but a real phone booth, personal, hand—held phone booth. i think he was gritting his teeth. bell had been focusing on developing a car phone and marty wasn't impressed. irate a car phone and marty wasn't impressed-— a car phone and marty wasn't imressed. ~ . , ., , , impressed. we had been trapped in our homes and _ impressed. we had been trapped in our homes and offices _ impressed. we had been trapped in our homes and offices by _ impressed. we had been trapped in our homes and offices by this - impressed. we had been trapped in | our homes and offices by this copper wire for over 100 years and now they were going to trap us in our cars and we are motorola's didn't believe that was the way to go. goodbye. the way the first call was made hasn't really changed, the phone converts your voice into an electric signal

which then modulates a radio way. the radio wave goes to a mast and the mass sends it to the person you are calling. and by reversing the process, that person can he speak. except there weren't many masts around 1973 and mobile phones are now unrecognisable from the first model. it now unrecognisable from the first model. , ., ., now unrecognisable from the first model. , . ., _, now unrecognisable from the first model. , . ., ., model. it is a real icon from the mobile phone — model. it is a real icon from the mobile phone timeline. - model. it is a real icon from the mobile phone timeline. this - model. it is a real icon from the | mobile phone timeline. this man knows about _ mobile phone timeline. this man knows about the _ mobile phone timeline. this man knows about the history - mobile phone timeline. this man knows about the history of - mobile phone timeline. this man| knows about the history of mobile phones, he has his own collection. here we have a true icon, the motor roller— here we have a true icon, the motor roller 8000, — here we have a true icon, the motor roller 8000, the first truly hand portable — roller 8000, the first truly hand portable mobile phone, conceived in 1973 when _ portable mobile phone, conceived in 1973 when the first phone call was made, _ 1973 when the first phone call was made, launched eventually in 1984 and that_ made, launched eventually in 1984 and that the cost about $4000 at the time _ and that the cost about $4000 at the time. would be about £9,400 today. and it _ time. would be about £9,400 today. and it is _ time. would be about £9,400 today. and it is pretty heavy, again. what is the battery life like? the battery life _ is the battery life like? the battery life and _ is the battery life like? the battery life and that - is the battery life like? the battery life and that was about 30 minutes — battery life and that was about 30 minutes. it will take about ten

sells, will capitalise the industry and that would be a national consumer awareness journey. but before long, it will be something we used to think, oh, well you know. 0k, used to think, oh, well you know. ok, the time has come, my lab grown chicken skewers already. thank you. the anticipation is killing me. this is my first ever taste of cultivated chicken. it is nice. now the real test. i am going to have the chicken on its own. without the patters and the onions. —— peppers. i don't think there is any way that i would be able to tell that this is not traditional chicken. the truth is, in the near future we are going to

have to rethink how we grow enough food for everyone. i have eaten insects, i have eaten salad grown in food computers and i have driven algae fed on co2 captured from a power station. there are plenty of really interesting food ideas out there. if we have got the stomach for them. and that is it for this week from singapore. if you would like to see more of my exploits, check us out on the socials as usual, thanks for watching and we will see you soon. hello there, good evening. it's been a beautiful day of weather for most of the uk with lots of blue sky and sunshine, as captured by our weather

watcher here in derbyshire, but a bit more cloud towards eastern coastal areas. still even, here, some sunny spells breaking through, and it's more or less the same again tomorrow — in fact, it could feel a little warmer for most, but there will be some rain later on in the day out towards the north and the west. most of us won't be seeing that rain until early on bank holiday monday morning. but overnight tonight, it's set to stay dry. lots of clear spells, especially through the central swathe of the country. out towards eastern coastal areas, some cloud, cloud thickening, too, across northern ireland. more cloud and a bit more of a southerly breeze, so frost—free without so much mist and fog as we start off sunday morning. so, easter sunday, lots of sunshine around for the vast majority of us. it will be quite cloudy towards eastern coastal areas — again, the cloud just coming in from the north sea, but that should break up, especially through the afternoon, so a sunnier day here. cool underneath the cloud across aberdeenshire, outbreaks of rain moving into northern ireland from our weather front, approaching western scotland by the end of the day. temperatures slightly higher, between 15—17 celsius quite widely. if we see 18 celsius — always possible, especially across central, southern england —

it will be the warmest day of the year so far. but of course, it's not set to last, the dry, warm weather, because we've got outbreaks of rain from these weather fronts, sweeping eastwards from sunday night into bank holiday monday morning. it's a much milder start to the day on bank holiday monday, outbreaks of rain clearing the east anglian coast as we head through the morning. there will be some bright and sunny spells behind, but also some rather hefty showers, and raining for much of the day — longer spells of rain towards the south coast, especially across the channel islands. temperatures gradually dropping throughout the day. this is how we'll end the afternoon, between about 10—14 celsius, so obviously not as warm with all that wet weather around, and it's staying unsettled as we head through much of the rest of next week. a deep area of low pressure swinging across england and wales, into scotland as we head through tuesday night and into wednesday. some strong gusty winds potentially on this and some outbreaks of rain. here's the outlook for our capital cities as we head through next week. as you can see, it is going to be really very unsettled, wet and windy, especially

towards the northwest, and also feeling a lot cooler.
