zimba bwe's newly re—elected president emmerson mnangagwa has called for peace and unity after being accused of winning a "fraudulent and illegitimate" election by the opposition mdc alliance. there have been some clashes with police. the mdc leader nelson chamisa says he'll challenge the result in court. the hollywood film producer harvey weinstein is trying to have criminal charges against him of rape, dismissed. his legal team are arguing that prosecutors should have shared email evidence with the grand jury that indicted him. mr weinstein denies all the charges. britain's prime minister, theresa may, has held informal talks with france's president macron at his summer retreat, to try to push her plan for leaving the european union. it's the latest in a series of british meetings with individual european leaders to try to secure a brexit agreement. now on bbc news, it's time for click. this week: computers dream of

electric puppies? can data prevent crop devastation? and will lara ever live down these issues? —— these shoes. planet earth is changing. daily. we humans are affecting its surface, its climate, its inhabitants. watching from ground level makes it difficult to make sense of it all, but these days we do have the data and we can crunch the numbers. and

when it comes to understanding the really big issues, those that have effects on eight truly global scale, visualising that data can turn millions of figures into something that everyone can understand. maps like these created by carney leakey —— carnegie mellon university is site connect satellite imagery with a wide range of datasets, of a wide range of geopolitical events. like refugee movement to the effects of coral bleaching on areas such as the great barrier reef. one particular area where modelling such as this can display the starkest impacts is flooding. you can see how important that extremely the research that we look at in miami is. raise the global temp richer by just look at in miami is. raise the global temp richer byjust two degrees and the sea in gulf is the entire area. —— temperature. and this here is bangladesh, where

rising water levels are putting many, rising water levels are putting any rising water levels are putting many, many people at risk. into any 17, a third of the country was left under water after monsoon rains, devastating crops and communities. but while technology cannot prevent rainfall on this scale, it can make predictions to help those in remote communities to try and stay one step ahead of the weather. paul carter has been looking at how one insurance company has been using its knowledge of risk to help the farmers fight back against the reins. —— rains. like farmers the world over, in bangladesh they have to battle the elements. but in their case, severe flooding could be a regular occurrence of. given the impact floods can have, the information and advice on what fun we should do with their crops is disseminated to communities through phone voice messages. or via call centres that farmers can call into. and for those

who don't have phones or live in remote off—line areas, there are also weatherboards at district points where farmers can come to receive information. when floods destroyed this farmers crops, it cost him about three months wages. these initiatives were set up by the bangladeshi government and an international charity that helps communities find sustainable solutions through technology. and now, a app being piloted is taking things even further. the gap sesame app uses machine learning with weather forecast so that farmers can make against decisions on when to plough the land, planet and apply fertilisers. this farmer is being advised to spread a fungicide to

protect the crops. by by this although these measures can be a big help, poor communities are often unaware of how vulnerable they actually are two extreme weather, or what they can do to lower the risks. another platform being used by the charity is being set out to assess this, measuring the strengths and wea knesses this, measuring the strengths and weaknesses of committees like those in this district. using the appfrmt

—— frmt, in this district. using the appfrmt -- frmt, all in this district. using the appfrmt —— frmt, all flood resistant management toolkit, look at factors such as what crops are grown, whether factors, and the flood prevention measures in place. in all, the technology looks at aytek indicators to come up with a very realistic picture of how an area can cope with bad weather. is quite a departure from traditional outlooks, which mostly considerfactors such as traditional outlooks, which mostly consider factors such as dams and reservoirs. the thinking behind this technology though, comes from another country altogether were flooding could also be an issue. seven and half thousand wanders away in switzerland, a partnership between ibm and is europe's consumers copy has looked deeply into what makes a good flood resilient. in the last few decades, flash flooding has cost switzerland of millions of pounds of. the resilience for us is notjust a new buzzword like sustainability. the

big challenge is that you often don't see it until the event has happened. so what we want to have is a set of strong indicators that tell you something about what might resilient look like it's something happens and then how can we strengthen those indicators were smack so it is all about not being derailed and not falling into a poverty trap, despite that there is risk out there. algorithm measures all the indicators and it generates all the indicators and it generates a numerical value on how resilient population is. so this helps us use what we call engineering judgement, 01’ what we call engineering judgement, or expertjudgement, to start sorting and organising the data so you can come up with these numerical things and i think that is a unique approach to. technology has been pivotal, but also kept simple so it can be used off—line. pivotal, but also kept simple so it can be used off-line. we need to work with civil devices so you don't have the most expensive hardware either. how easy is it to sell it as a concept? i think we need to move

away from this, what is my saving if ido away from this, what is my saving if i do this? to much more a point of trying to answer the question, what is the cost of doing nothing? back in bangladesh, for farmers is the cost of doing nothing? back in bangladesh, forfarmers in this area, the cost of floods has been very high. just how vulnerable the area is is being revealed by the researchers. waterlogging hampers people's livelihoods and that leads to mass migration. by working together and making proper plans, it is hoped that the technology could help reduce the risk to their livelihoods when floods hit. hello and welcome to the week in technology. it was the week that facebook removed a number of accou nts facebook removed a number of accounts from facebook and instagram. the social network believes the accounts were involved ina believes the accounts were involved in a co—ordinated campaign to influence the upcoming us mid—term elections. and a usjudge has blocked the online release of blueprints of 3—d printed guns. the work of american self—confessed cryptography and kissed kodi wilson,

removing blind spot. things are not a lwa ys removing blind spot. things are not always as they seen and this week, i've been getting my hands, eyes, it yea rs i've been getting my hands, eyes, it years and feet on some of the latest, more unusual gadgets. i'm about to put on some glasses to listen to some music. way owl. that amazing. is not quite bright enough for sunglasses, don't really need the sunglasses right now, but that sound is incredible and i can hear the world are around me, i can hear some roadworks but i can also hear some roadworks but i can also hear some cars, so that feels nice and safe. the voxos sunglasses, which can also be made as description lens sunglasses use bone conduction technology to provide sound and they're built in microphone means you can make calls too. great, as long as you don't mind looking like

this. or you could use them with a backing app for directions. hello, ta ke backing app for directions. hello, take me to brick lane. but will they do thejob well, take me to brick lane. but will they do the job well, would you pay £200 for these sunglasses? and there are plenty of other interesting headphones out there. and here i had a pairof headphones out there. and here i had a pair of headphones that are all about recording 3—d audio. now, the microphones are positioned here, so they will be taking in the sound just as your ears would be. the aim being to recreate sound exactly as you hear it. book audio allows you to wirelessly pick up your surroundings in by new rule sound, as well as catch you by your phone 01’ as well as catch you by your phone or with a wi—fi connection. while you may get the greatest benefit from these at something like a live music event, i have been putting them to the test in everyday situations. here there is music playing, people making juices and a

lot of sound around the. i'm going to record it, but at the same time it also takes a video. so i took the video somewhere quieter to listen back. they are not the most co mforta ble back. they are not the most comfortable headphones to wear, but the focus here is on the recording element. ok, that might not have the most exciting things to listen to the sound from but it really feels like you are there, you can hear things happening over there, over there. 3—d element really, really is impressive. so we sorted for sound. next up is this. it is a wearable keyboard and mouse, of course. what else? once you have synchronised it toa else? once you have synchronised it to a bluetooth device, you will be able to type like tapping your hand onto any hard surface. at a have to warn you , onto any hard surface. at a have to warn you, it takes quite a lot of practice. can be worn on either hand and in thai to check aside from its

own preset way of typing, you can —— you can put your own commence in the. but there is a app that game if iis the. but there is a app that game if i is the process of learning. ok, i have only learned how to do ten letters of the alphabet and it is already getting confusing. but the game is quite addictive, i am enjoying learning, but in terms of this becoming a quick and easy way to type, i and slightly dubious, i would have to invest a lot of time. it can also be used to control app' 01’ games, it can also be used to control app' or games, unless you'd be interested in an idea to burn extra calories while gaming. i am about to go on a vr treadmill, the concept is not new but the consumer version is. i have been warned that it is very, very slippery. ok. the fact i am playing a computer game makes this quite compelling. goodness. iam a computer game makes this quite compelling. goodness. i am trying not to hit the walls. i am so glad i can hold on! how fast do they want

me to run? i am going display this time. testing all of this has been great fun, but it has just left me feeling like i would like to go outside for a normal run with just my normal pair of headphones. love the flip—flops, lara. and now we are going back to mit in boston. i have come to the media lab red tory, containing floors of research of expensive to touch, taste, sight and sound. this place is full of really creative people, but behind this door are three guys that i try to make us all more creative by hacking how drones. dreams are weird. mine are, at

least. they are not really understood. but some think they can be useful in the waking world. it's not only the fact that you nap after thinking of a problem, but what you dream about during that snap drives problem—solving. really cool research showing that you have a ten times increase in the likelihood of solving a problem if you have a dream about that problem and in that. the trick, though, is remembering what you've jumped about. to do this, famously creative minds likes of dali, nicolette hasluck and thomas anderson all tried to wake themselves up once they entered this so—called genius gap between the conscious and the unconscious. —— nicolette hasluck and thomas edison. they would do it by holding a steel ball or a spoon in their hand. when they dropped off, they dropped it, and it would bring them to. this is going to go

on the inside, writing here. bring them to. this is going to go on the inside, writing herelj bring them to. this is going to go on the inside, writing here. i am currently being fitted with the media lab's method, which involves a glove and talking robot. you are falling asleep. what is happening here is we are taking these three bios signals, your heart and your scan and your muscles, and we are looking for this state of sleep in between fully awake and fully asleep. what we are doing is, we are watching, watching, watching, and right as you descend into the next stage of sleep, we introduce a little audio from the robot. and that bit of audio knocks you, so you are not fully asleep. and then we see of whatever word we use will in fa ct see of whatever word we use will in fact enter the dream. by introducing the subject of your problem into your dream the subject of your problem into yourdream and the subject of your problem into your dream and then listening back toa your dream and then listening back to a recording of your so—called hypno rogic mumblings, you mayjust find that she hit on a creative solution. —— hypnogogic. specifically because in that moment you are hyper associative. your

cognition is really a lustre, it is really flexible. you don't have that same capacity to review and be critical of your thoughts, so you generate really weird, aber and, diversion thoughts, things that come to you as dreams but which you can later use as creative insights. you are falling asleep. if, that is, you can bear listening to the weird conversations that you end up having, like this recording of one experiment. you are falling asleep. think of a fort. a40. tomic, what are you thinking? in testing, the students found that people who used this method could think of more creative uses for objects and they wrote longer stories with mortaring is. and, you know, something tells me that the sleep glove may have a news to come up sleep glove may have a news to come up with the concept for its own promo video. either that, up with the concept for its own promo video. eitherthat, orthis up with the concept for its own promo video. either that, or this is how adam likes to sleep most nights.

and just before you take a nap to boost your creativity, here is a question we have asked their lot on this programme. ten computers be creative? well, here rabi winners of the recent $100,000 robot heart contest. they have all been painted bya contest. they have all been painted by a robot arm. and although this one is a copy of a well—known painting by cezanne, this one uses artificial intelligence to interpret an image, possibly the same way that an image, possibly the same way that a human artist would. and as computers learn more about the visual world, weird things start to happen. you have some artists who work with deep dream, hallucinatory aesthetic. then we have others who work with style transfer, which is about turning an image into something that looks like it has been made by monash picasso. ——

monet or. graphics company nvidia has previously used neural networks to absorb a bank of famous photos and then started growing its own nonexistence celebrities. now we have a new breed of artists, showing at places like the photographers gallery here in london. now, they are not photographers. they are not even posed photo cgi artists. they call themselves neurographers, and what they do is use two neural networks, want to create random images and want a curator them. you can think of the discriminator is a face expert. so then the generator tries again, gets rejected again. at 330, welcome you don't see features yet, but i see faces. and that 4000 tries later, a generator who has never seen a face before is pulling out features with faces. and these

people don't exist. they are totally imagined. they let you guys can pay, and decide for yourself, if we are living in a world where machines now have an imagination. mario kling and coined the term neurographer, and we caught up with him at bp three prize for post— photography which was presented at the photographers gallery. he is trying to create accurate human faces, but rather see surprising and beautiful work can can be produced by a eye. —— by ai. one of his neural networks has been trained on 19th—century portage, which can then take a video of a real face which can then take a video of a realface and which can then take a video of a real face and create one thing you from what it sees. i definitely see that many, traditional artists, are getting very fascinated with the potential of having that machine is a new source of inspiration for a new instruments to work with. as usual, i guess it will take quite a while until this becomes really a fully accepted element in

contemporary art. not that the idea of creating and curating random images is a —— is that all new. it was something that francis bacon explained in a series of interviews with the bbc and 1960s. explained in a series of interviews with the bbc and 196mm explained in a series of interviews with the bbc and 1960s. if anything ever does work in my case, it works from that moment when consciously, i don't know what i'm doing. from that moment when consciously, i don't know what i'm doinglj from that moment when consciously, i don't know what i'm doing. i often get that from people, saying that what i do remind them of francis bacon. and i use this, well, kind of brandon influence. —— random. and also be part of throwing away is definitely part of the process, because in a few hours these models can produce hundreds, thousands of variations, and different images. currently i may be keeping 1% of what the model producers. the fact that many of these images are pleasing to look out does once again raise the question about what art

is, and who or what is capable of producing it. in a recent book on artificial intelligence, new scientists argued that it is —— if it is so easy to break down the style of some of the world's most original composers into computer code, that means some of the best human artists are more machinelike than we would like to think. robbie barrass is another ai artist known for his computer—generated landscapes, and as you enjoy them, you might ponder whether the question should no longer be, "our machines capable of creativity", but rather, "are some forms of creativity machinelike"? maybe this kind of religious appreciation of single pieces is something that will go away with this potential of the machines being able to produce more, and then the question is, yes, what do we appreciate then about them? and then the question is, yes, what do we appreciate then about them7m the way, the music that you have

been listening to while you've been watching this piece? well, no, it's not that i'll be. it was created by an artificial intelligence programmes by author, composer and scientist david cope. personally i thought it sounded brilliant, but i am sure there are those watching who say that is because you have no taste. fair enough. that's it for this week. and forget you can follow us on twitter and on facebook. thanks for watching, and we will see you soon. hello there. we had a bit of rain around on friday across parts of northern england, north wales, into the midlands as well, but for most places it was another warm and dry day.

this is how weak ended the day in topsham in devon. heading towards the weekend we will see scenes a little bit like this, more spells of sunshine around and it is looking dry and warm wherever you are. just the chance of the odd shower across northern and western parts of scotland, but it should be a dry weekend elsewhere. heading through the day on saturday, we have high pressure building its way in from the west, a couple of weak weather fronts pushing further south across the uk, introducing slightly fresher conditions to northern and western parts. down towards the south—east of england, that this where we keep the heat and humidity through the day on saturday. most places dry, best of sunshine towards the south and east, particularly for northwest scotland we will have a bit more cloud, perhaps the odd shower. temperatures not quite as hot, the yellow colours on the map, but down towards southern england we will see those red colours returning. the heat building once again in the south—east, temperatures of 33 celsius on fridays at the 29 or 30 degrees by the time it gets to saturday, not quite as hot as recent days and slightly fresher further north. overnight into sunday and most of us are staying dry with light winds, pretty warm but not as quiet as humid as it has been recently. a few showers towards the north—west of scotland, dry elsewhere and temperatures falling

between 12—16 degrees for most towns and cities as sunday morning. the second half of the weekend and it is high pressure once again that is going to be driving our weather, moving its way in from the west and holding on for the next few days. sunday looks like another dry day for most, northern scotland seeing a bit more cloud, bringing the prospect of a few more showers to the highlands of scotland too. sunny spells for scotland, northern ireland and northern england, on spells of sunshine for england and wales and it is towards the south—east that we see the highest temperatures. generally 18—29 degrees for most of us on sunday. into monday and we will start to see a bit more cloud, with a weak front into northern ireland and the west of scotland, one or two showers and perhaps in the far north of england. further south again, a dry day with lots of sunshine and light wind. we could see 31 celsius, a little bit more warmer over time it gets to monday and a touch fresher north. to the middle part of the week and those temperatures will get down a little bit, most places staying dry. a few showers in the west.
