amazing stuff. that's all from sportsday. we'll have more throughout the evening. next up, it's click. massive attack's teardrop plays. it is pretty far out there, but it really suits the music and what they're about, i think. in his birmingham studio, artist harley davies is painting a unique work that is much, much more than meets the eye. it's mind—blowing to think that, when you consider how much data there must be out there.
7:46 pm
it's interesting for the future, i'd say. the artwork is the album cover of the hugely popular and influential mezzanine album by massive attack. and to celebrate its 20th anniversary, the band agreed to have this music encoded in dna and then added to several spray paint cans. it means harley's painting will hold thousands of copies of the album and to find out how, i have come here to a lab in zurich to meet one of the pioneers of using genetic code to store data. and so here's the freezer where we keep the dna. right, ok, this is where the magic happens. exactly. so in here. it comes in an enormous box, all really cold. and you buy in dna? we buy in the dna. dr grass has encoded the music already to be sequenced into the dna. that work is done by one of several companies now offering genetic code to order. so they make the dna in the sequence that encodes for the album.
7:47 pm
so we have the sequence of a, c, t and g, and so they take a and then they add a c and add a t so that will encode for, i don't know, 0010 or something like that. and then you have to make, because the album is much more than just a few zeros and ones, you have to make a lot of those dna sequences. so the whole album is distributed over the tubes, so there is no particular order. it starts at the beginning and at the end, and so every tube contains a million different short dna sequences and every sequence has a number stored in it to tell us where it sits in the overall picture of the album. so inside this tube is effectively about the equivalent of one of the tracks on the album. and how much does this cost? 50 megabytes, $1000 per megabyte.
7:48 pm
that's about $15,000 to store the album. it's a lot, but you only have to do that once and then you can make enormous amounts of copies of it, because one key advantage of dna, i think, over all storage technologies we have, that essentially for free — nearly for free — you can make billions of copies. i don't know if you see it, it's a very small blob. oh, wow, 0k. so that, there's an opaque section at the end of this tube. in there, there's billions of very, very small glass particles and in the glass particles, we have encapsulated the dna. so we have grown glass around, we've directed glass to grow around the dna. and it protects the dna. very similar to what you know from amber. right, and the amber is protecting it from decaying for potentially millions of years. exactly. and here, for millions of years, in our dna in the glass, for probably 1000 years, it protects the album from decaying.
7:49 pm
so you can still hopefully play it in 1000 years. how many copies of the album are inside here then? just the one? no, so we put a million copies inside. even if you don't spray with the whole can, you certainly have a copy of the album in there. so harley's picture paints much more than 1000 words. it's not only the first album cover artwork to actually include the album. a painting this size could store enough data to hold every album, picture, photo, book and recording, audio and film ever created in the history of mankind. so how can we read the information? well, that's one fly in the amber at the moment. this machine takes 17 hours to do it. it's come down from about a week but still, imagine pressing play and waiting that long. so we may be several years away
7:50 pm
from dna being practicalfor storage but at least it will hang around for thousands of years, and in a format we'll always recognise when we see it. 0r hear it. a few weeks ago, we visited the amazon spheres, part of the tech giant's headquarters in seattle. we met the people behind its voice recognition tool alexa and saw what else we'll be talking to soon. as the tech gets better, it could, one day, become the way that we interact with our devices. now, that prompted this question from a viewer. thanks, simon,
7:51 pm
that's a really good point and, yeah, apple homepod gives some control to deaf users through the use of a touchpad, but nowhere near enough to really use it. google‘s assistant can control a smart device by typing requests on a smartphone, and the captions feature is available on the versions of alexa with a screen. news, weather and timers can be activated with tap. all of this is quite basic, so abhishek singh has decided to show them how it could be done. he's created a simple algorithm to do this. the camera sees what he signs and turns it into text that alexa can understand and respond to. now, it only does a few words, but the point is to inspire the big companies into action.
7:52 pm
last month, google released a couple of new accessibility apps for deaf users who use its android devices, and lara and click trainee maddie have been putting them to the test. i lost my hearing when i was seven, and about a year after that, i got a cochlear implant which has helped me a lot, but even now in certain situations, i find it really hard to hear. so when i'm in noisy cafes or at a dinner party, my hearing is not the best. we've deliberately come to a coffee shop where there's real, everyday noise all around us to demonstrate these. maddie here has been testing them in various different environments. we're going to start off with google live transcribe. and it does what it says, instantly and simply creating a script of your conversation. it can do so in 70 languages and dialects, with quite impressive accuracy, it seems. yeah, it seems to do really,
7:53 pm
really well with people talking. with one or two people talking, it works really well. obviously, the further away you get from it, the worse it gets, and the closer you get, the more accurate it becomes. so the underlying technology is automatic speech recognition technology, and what that is is that's a way of us taking all sorts of known speech from recordings and basically training algorithms on top of it so that it learns all of the nuances, all of the context that we understand as people. we also have here google‘s sound amplifier app. you need to attach a pair of headphones to the device and from there, it can turn up the volume on different elements of what you're listening to. so it may be the quieter background noise that you want to make louder, whilst keeping the main sounds you're listening to at the time,
7:54 pm
which could be some music, at the same volume. now, how useful did you find this was, maddie? i thought it was quite cool that you could play music and still hear stuff from the outside world at the same time. the phone's microphone picks up the ambient sound and, from there, machine learning and artificial intelligence isolate the elements. that could make it possible to, say, make speech louder and the sound of an air—conditioning unit quieter. for people with worse hearing, it would be much more useful because itjust boosts that noise around you. so when you're less comfortable with your hearing, it gives you that little bit of security, that you could have that little bit of extra volume. it took be a good half an hourjust focusing on the app, playing with all the toggles, because it builds into the settings on your phone, so it took me a while to find the right settings for me. these are what i would call accessibility first applications, in that we're not taking an existing product and making it more accessible.
7:55 pm
we're making, in both cases, the real world more accessible using these technologies that exist on a smartphone and in the cloud today. the big game—changer was back in 2014, when the first hearing aids with the ability to communicate with an iphone came out. that then opened up a lot of possibilities because you've not just got the processing power of the hearing aid, you've got the processing power of the smartphone as well. apple added similar functionality to their airpods last year, with live listen allowing you to place your phone or ipad near the sound you want amplified. and now starkey, one of the leading hearing aid brands, will be adding full detection and a virtual assistant to their device that already features live translation and activity tracking. a live translation feature is promised, along with activity tracking, and an app to host a whole lot of data. it looks at your constant communication with other people and therefore, it's measuring how much social interaction you're having. and there are also sensors
7:56 pm
inside the hearing aid, so motion sensors inside the hearing aid, which are looking at how much movement you've got. there has been found to be a relationship between cognitive decline and hearing health. but when it comes to google‘s latest releases, even if they're not proving quite perfect yet, they do harness the power of the fiercest weapon most of us have on us all the time. and that's it for the shortcut of click for this week. the full—length version is up on iplayer, waiting for you right now. and don't forget, we also live across social media — instagram, youtube, facebook and twitter. thank you very much for watching, and we will see you soon. and it was another very mild one across the uk today.
7:57 pm
not cold him 5—9d early on monday morning. some showers getting into scotland and northern ireland. not cold. temperatures are typically between 5—9 degrees early on monday morning. we should be getting this during the daytime. this is the overnight temperature. and then tomorrow, showers frequent in western scotland, central scotland, too, some in northern ireland. one or two showers scattered around as well, the southeast for example, london, southampton could catch some spots of rain. a bit more cloud tomorrow, and as a result, the temperatures will be lower, around about, say, 11 or 12 degrees at best. tuesday will see some rain sweeping into northwestern parts of the country.
7:58 pm
it's still a south—westerly wind, which means it's going to be mild, relatively, for this time of the year. and then from wednesday, thursday into friday, looks like those temperatures will be climbing back into the mid—teens. this is bbc news. the headlines at eight o'clock... the family of the british teenager who joined the islamic state group say she's given birth in syria. shamima begum says she wants to return to the uk after fleeing the last is stronghold. it comes as president trump calls on britain and other european nations to put captured islamic state fighters on trial. stranded flybmi passengers speak of frustration after the airline went into administration and cancelled all flights. a man has been arrested in brighton after handing himself into police investigating the murder of a 22—year—old man found stabbed in a car. theresa may writes to every conservative mp, urging them to put aside their personal differences over brexit and come together in the national interest millions could see ther when the amount they have to put
