but people concerned about the climate say the government should be advising us — to switch from beef to chicken, and to cut down on all meat. to stay within safe climate limits, we need to tackle the amount of meat we're eating. but actually lower meat diets that are higher in vegetables and plant proteins are also better for our health, so it's a win—win situation. there's been a huge rise in interest in flexitarianism — people eating less meat — and businesses are starting to respond to that. so the supermarkets have been introducing lots of great ranges now for people wanting to choose alternatives to meat. tomorrow the government launches green gb week, to shift britain towards a future with zero carbon emissions. scientists say that cutting down on meat must be on the policy menu. roger harrabin, bbc news. tharanga bit further east solely for

london, and at the moment it is home toa london, and at the moment it is home to a curious painting. it is not what it seems. what i like about the work that we are offering, is that at first blush it looks like a portrait. the frame is all part of that. you approach it assuming it is like everything else you have seen, and then when you read the label and you read and impact this has been created by an artificial intelligence programme —— in fact, i think that is the shock. this is the latest image of a type we have seen before on click, images that have been created using a form of artificial intelligence called generative adversarial networks. as far as generative adversarial networks. as farasi generative adversarial networks. as far as i understand it the computer

split itself into and one half of the computer looks through 5000 or 15,000 portraits, learns what a portrait is and makes its own version. it is not a mash up, it is not photoshop. it has created a portrait based on the rules that it has learned, and the other half of the computer looks through 5001 and if it can pick out the computer worm to lead to one the other half goes back to the beginning and reruns it and reruns it until the discriminator cannot spot with the computer one is and what the human one is and at that point it pops it out. this is the first piece of ai art to go under the hammer at a major auction at christie's in new york on the 25th of october. the picture generating algorithm was trained by a collective called obvious, three guys who live in an unassuming flat in paris. one of the

most important aspects of this is to have great ingredients, so i guess for what we do, feeding data to algorithms and according to the data is crucial. if we see in the output something that speaks to us, we believe that it will speak to other people also. he is one of a family of the computer—generated pictures, is another, and urban art collector whose museum lives in the coding school also in paris. what truly astonished me about obvious is that they created a hybrid between a startup and artist. what was great, we realised afterwards, was that a form of art that was subversive was brought here into this school, which also has a subversive spirit. the

discussion goes on about whether computer—generated works could ever be considered art. 0bvious told us that the images themselves are not important, they are making conceptual art, and you need to understand the concepts which in this case is the ai behind the scenes. it would probably be a mistake as some have done to compare the work of obvious with the masters of the early 20th century. perhaps instead they should be compared to works of artist like damien hirst and jeff koons. and maybe the skill actually lies with the inventor of the generative adversarial network method, google rain researcher ian goodfellow, a surname which when translated into french he comes though not me, which brings us right back to at montebello me. we make a physical piece and we think that it makes the art more accessible because it is more traditional to have a physical piece and people can

relate to it. just as facebook creates no can't —— no content, huber has no taxis and airbnb on snow properties digital out galleries of the future like this place in paris might not have any physical paintings in it at all, and that will make these printed pieces by obvious last week we reported on the new full frame ea rless cameras last week we reported on the new full frame earless cameras being shown off in germany at the world's largest camera expo. dan simmons played with the latest creations from canon, nikon, sony and panasonic's from canon, nikon, sony and pa nasonic‘s brand from canon, nikon, sony and panasonic's brand limit. this week is going to take us through a few other highlights from the show including these. you don't have to shake it but it's

pa rt you don't have to shake it but it's part of the culture. it's really being driven by the youth market, so we have seen being driven by the youth market, so we have seen enormous being driven by the youth market, so we have seen enormous growth in the la st we have seen enormous growth in the last couple of years, and this year alone we are expecting to sell ten instinct cameras. it is not shared. it is something that the way from the digital world. they're actually appreciate it —— appreciating them or you can put your phone down and enjoy the moment, but still capture the moment. you get something amazingly tangible with natural that —— with an actual photo. amazingly tangible with natural that -- with an actual photo. how long will something like this last?l good 20 years that it can last. this does have a selfie mode, shelley?‘ little bit closer. there we go, nice one snap from dan who's with us now. so, this is clearly a move away from digital. do you think it is a fad or will it last? it is the only sect or of the camera man to lead the market that's growing apart from your list cameras we saw last week but in

christ it is not it seems fujifilm have come up with something new coming out next week. this is the same emphatic that it has a screen on the back. so that is digital. it ta kes on the back. so that is digital. it takes video. it is not a video camera, but when we start going here we are recording a bit of omar on the left and the camera person today and we can't stop it. ander is going to be about 20—30 frames that we can now scroll around in between and decide which one of those we end up wanting to print. there is no more pointing, shooting, hoping. wanting to print. there is no more pointing, shooting, hopinglj thought pointing, shooting, hoping.” thought that was half of the fund to be honest. what else have you got? 100 megapixel camera. it isjust a model at the moment coming out next year, and asked them why would we need 100 megapixels? better clarity, wider tone of colours and when you look at black and white moral natural back and —— more natural black and white as well. i would say about a three, 82, a1, that is we

start to see a difference in that size of image. even in smaller size you see much better detail and clarity. i could see you are not convinced. how about we lighten things up? what you think this could be used for? interrogation? it is actually at 360 degrees camera when it is close like that, but when the two wide angle lenses popped open and transforms into a 3—d stereoscopic camera. you get superwide shot which has more depth when you play back in one of these. platforms like facebook and youtube support playback. is that one on sale yet? no. it was a prototype and goes on sale next year, but i have a piece of kit that went on sale at two days ago. this is the not only with the increased resolution from four k to 5.7 kaser you get a better 360 degrees look to the whole thing,

but it also has a stabilisation on it like i have not seen on any other camera using your smartphone. not a laptop, it doesn't need postproduction, it is all done in the app on your smartphone, very impressive. it also does something else that we have not seen any other camera on this programme do. can you guess what that is? can it fly? yes it can. seriously? well caught, thank you. just. as it went through the air, it takes video in the air and that video can slow down, slow motion and you get this beautiful arc shot of something shot below and you can direct it because it is 360 and you can just you can direct it because it is 360 and you canjust point you can direct it because it is 360 and you can just point downward as opposed to be getting something about the air. if it went on the ground at the $400 piece of kit you probably don't want to damage too much. $400 you say? welcome. to the week in tech, the

message ever calls and of course come with augmented reality overlays so you can pretend to be a paid. technology at its finest. —— be a paid. that was nick. now this month is adhd awareness month. this is a condition which used to make 100 —— which... they can continue into adulthood. a new study from kings couege adulthood. a new study from kings college london is looking at treating the disorder using different kinds of technologies, that includes gaming, which is ironic because technology is often seen as an ironic because technology is often seen as an aggregator. we sent sarah emmett who have had adhd since childhood to meet the researchers behind the study. i'm sarah emmett andi behind the study. i'm sarah emmett and i had adhd. it stands for attention deficit hyperactivity disorder. like most people, i have thoughts buzzing around my head all the time. it's very much like a

volga square except with adhd it is really difficult to prioritise which box should come first or which thoughts to focus on. it's usually the one that is most stimulating so right now stood here it is definitelyjumping right now stood here it is definitely jumping on the right now stood here it is definitelyjumping on the lion. so right now, stood here, it's definitelyjumping on the lion. it can become a vicious circle with more and more ideas and thoughts presenting themselves as the most important, until. ..gridlock. studies of the brains of people with adhd show abnormalities in the right prefrontal cortex, the area responsible for self—control and attention. research is now using technology to affect neurological changes to this region. by activating this, which is often less engaged in the brains of people with adhd, researchers are hoping to improve concentration. stimulant medication, interestingly enough, also enhances the activity of this right frontal area. but the medication has the problem that has side—effects, people don't like the side—effects, of course.

and it has — longer term effects have not been shown. it works fantastically well for a year. then we've shown that the brain adapts to the drug. when the brain adapts to the drug the drug does not work any more. yeah. so that's why we want to find alternative brain therapies for adhd. there are cognitive training apps, known as brain training apps, that you can buy off the shelf, but none of them are proved to help with adhd. but now pioneering new treatments are on the horizon. this isjust to dampen the noise. so i volunteered myself to act as a guinea pig to test out the exercises the experts are coming up with. the research being done here affects the plasticity of the brain, meaning the ability to change by reorganising itself and form new connections. one possible consequence is improved concentration and self—control. for the first experiment, i climbed into a brain imaging scanner that is calibrated to pick up the activity in the brain's right prefrontal cortex. the scanner is an mri machine

connected to a game that sends a rocketeer up into space. when my mind is focused on the area of the brain being scanned, the rocketeer goes up. the more i use that area of my brain, the higher he goes. so i'm enhancing my own brain activity. ready for the brain stimulation? yes. next up, a different exercise to stimulate my brain. the difference is this is a double whammy. at the same time as gaming, my brain will also receive external stimulations through small electrical signals that are delivered by bristles at the side of a helmet i'll have to wear. but like any good scientific experiment, i had to do a before and after test to see how much my concentration had improved as a result of the exercise. so first a baseline test to establish my current level of concentration. ifeel like my brain is trying to find a pattern. mm—hm.

and there isn't one. what was only a six—minute test felt like an eternity. so i can only guess that my concentration on the "before" test is pretty appalling. now for the actual exercise. using small electrical currents to stimulate my prefrontal cortex, i was put through my paces once again. pirate. monkey. soory. i am really bashing the ipad. sorry. it is definitely fun and games, ijust hope it is doing me some good. very good. i have earned a medal. now for the final test to establish whether my concentration has improved. before the stimulation you had almost 40% mistakes. yeah. after the stimulations you had only 25%. and on top of that you were much faster. for me, the way i felt was very important. i didn't really mind how the data showed, but actually looking at it, i feel really proud of myself. it's a huge difference. the neural feedback, like the one you did

with the rocketeer, that is a pilot study and we found the effect lasts for one year. you are training the brain. it makes sense. it changes the brain and therefore it has a more lasting effect than an external pill, which you just... which is a passive thing, you get the pill and next day the effect is back. it's like the first time that dorothy steps into the wonderful world of oz. black and white photos turned into glorious technicolour. but artist marina amaral has used technology, not magic, to digitally edit 200 pictures for her new book, the colour of time. she's colourised photos from some of the greatest moments in history. taking up to two weeks to modernise each image. so the process is very similar to what traditional painters do. i need to select every tiny detail of the photo by hand.

i need to go building layers upon layers of colours and mixing them and trying to capture the original atmosphere. the project is about using colour to connect us to the past, helping us to relate to the people and the emotions captured in the images. it is only now that technology has allowed marina to do this in so much detail. i think the fact that we have photoshop and also the digital tablets that we have now facilitate the process a lot. when you are colourising movies, for example, the process is very different. that's because colourising 24 frames for every single second of footage was far too time—consuming to do well. until now. to mark the 100 years since the end of the first world war, movie director sir peterjackson has embarked on a project to colourise films captured in the trenches. and marc cieslak caught up with him

at the imperial war museum. they shall not grow old is a new documentary film about the first world war, directed by academy award winner sir peterjackson. using audio recorded in the 19605 and 70s, veterans of the western front recollect their wartime experiences. you knew what was going on within your vision, beyond that you hadn't got a clue. these stories are told over footage of the war which has been painstakingly restored, colourised, and converted into 3—d byjackson's team at wingnut films in new zealand. audio has been added in places, but the film develops entirely from the soldiers' perspective — in their own words. their stories are told in an imaginative and startling way. the film flips from the patriotic fervour of vetera ns' accou nts of their enlistment for war to the brutal and shocking realities of day to day life and death in the trenches.

some of these stories are told in an amazingly matter—of—fact way. you lived like tramps. you didn't polish any buttons. you wore any uniform, bits that you liked and nobody worried. all they were concerned with was that you were fit to fight. peterjackson and his team trawled through over 600 hours of audio and 100 hours of film footage, provided by the imperial war museum's archive, in order to construct the film. vfx wizardry smooths the movements of images, removing any jerky pictures. it's a very unusual method of storytelling. that struck me straightaway. it feels different to almost any war documentary i've seen in the past. the brief that they gave me was, on the surface it was very simple and very wide open, itjust said you can do anything you want. but we would like you to use our archive film in a way that is unusual. so the first idea i had was i will get them to send me some

2k scans, material like three orfour minutes, send it to me in new zealand where we have our big visual effects department. i thought, how well can we restore this film? that blew me away. we were able to restore it way better than i thought we could. it took us a while to figure out all the techniques, because we were taking it further than anyone had with restoration before. how did you ensure that the colourisation process, the restoration process, and the 3—d didn't overwhelm the story, the stories that you were telling, but enhanced the stories you were telling? i wanted it to be in colour. they saw it in colour. we think of the war as a black and white war. but it wasn't a black and white war to them. they didn't see black and white, so why should we show it in black and white? so i thought, well, let's make it colour. in doing so, the same as we did the restoration, it had to be the best colourisation we have ever seen. what i found with colourisation is the longer you spend on it the better it gets.

that led to the next thing, because once you restore it, the thing that happens is that this film becomes about people, about human beings, the faces of these guys and the nuances, the humanity. it comes out at you like a freight train. they shall not grow old will be shown in full on the bbc. it will also get an outing on the big screen as part of the london film festival. it's not the only work at the festival which provides a window into the past. the british film institute has been digitally restoring 120—year—old victorian films. unusually, these movies were shot on 68 millimetre film, almost twice the size of conventional 35mm film stock. it's a joy to restore these films. because you're dealing with this large format picture with an enormous amount of detail in it. the only problem is that it is so fragile. so you have to unroll it really carefully, because otherwise the emulsion can peel off. the films themselves are only

about a minute in duration, depicting events like a royal tea party at clarence house. while their runtime may be small, the size of the original film means it can be blown up and will be projected onto an imax screen as part of the festival, allowing us a little glimpse of the past on the biggest screen around. that was marc talking to sir peterjackson. that's it for this week. don't forget we live on facebook and twitter @bbcclick. thank you very much for watching. we will see you soon. the rain has been a bit further east

today riverdale —— river levels have dropped a little particularly in wales. the rain is still around across lincolnshire, east anglia in the south, may well pepped up again later in the night pushing back into the midlands towards southeast wheels and the west country two. a fair bit of cloud in the way should keep temperatures up but it gets clear and older the further north and west you go. temperatures not farfrom and west you go. temperatures not far from freezing in eastern scotland. the cloud breaking appear, sunny skies developing more widely in scotland and northern ireland. wales looked pretty cloudy, the rain mainly for the midlands and east anglia and the south east, could be heavy at times, make it late sunshine giving temperatures a boost in the southeast, but otherwise 12-15d. in the southeast, but otherwise 12—15d. moving into tuesday the rain is pretty much gone, but we are left with cloud, mist and fog around in the morning across many eastern parts of england and we have a band of rain, not much on that coming in from the northwest but either side of that, some sunshine in most

tempter sitting 30—17dc. this is bbc news. the headlines... the eu's chief negotiator says despite crunch talks with the brexit secretary today there are still key unresolved issues. the pace of the negotiations pick up ahead of wednesday's summit of eu leaders. the ambassadors from the other 27 member countries hold a separate meeting. after the storm, the clean up — roads and railway continue to struggle after a battering from storm callum. france, germany and the uk issue a joint statement demanding a ‘credible investigation' in to the disappearance of the journalist, jamal khashoggi — who vanished after visiting saudi arabia's consulate in turkey. also in the news this evening: angela merkel‘s regional allies in bavaria look to have experienced their worst election result since 1950.
