i see just part of my job to confront multi-dose on policies and development to put the spotlight on issues that matter most hunger food security question marcia knightley. a lot has been achieved with so much more needs to be done and i think people have to be at the heart of solutions my name is on the type she's on and i wanted to tell you. we leave traces everywhere and everything we touch. even when we brief. most of the telling these traces are invisible but they can still reveal a lot about us for example i think the prince and the proteins in our head. since the start of the coronavirus pandemic we've had to contend with the loss of these

invisible traces really behind. viruses that i excelled into the egg for example. which have turned our world upside down. join us as we play detective on tomorrow today the science show on d w. images like these have become the new normal people queuing to get tested for covert 19. the tests are meant to get the pandemic under control and better understand the spread of the disease. there are 3 space to keep roach it's the antibody test detects a pulse infection and requires a blood sample. the blood is tested for antibodies that would have been produced by the means. during the illness. the other 2 tests are meant to detect

a current infection of cells to. the antigen test requires a swab from the back of your nose or throat and detects protein it's one of the surface of the virus. the results are quick but not as accurate as it p.c.r. test here you also need saliva or in nasal swab. these tests are engineered to identify genetic material called r n a. p.c.l. a test is the most reliable. but it takes up more time and resources and so it cannot be easily used for mass testing. but pool testing for the virus could change that mathematicians in rwanda have now developed an algorithm to do just that.

in the fight against the pandemic we wonder coronavirus task force relies on comprehensive contact tracing. to get an up to date picture of how much the corona virus has spread rwanda regularly tests a cross-section of the population using an ingenious strategy called pool testing. the brains behind this strategy is professor wilfred who is director of research at the african institute for mathematical science or a i.m.s. global network. that's why if you go to the community and just people it doesn't tell you how many people are actually infected because you're going to everybody so you almost some people i'm sort of go from the sample to the truth to reality you

need my mind to go more those. are the calculations involved complex algorithms and define has translated them for us into an example from everyday life. the idea of your own borders thing is really simple so imagine that you have 9 cups of beans and you're thought out all of those god has bobbins and in order to church which go up as the bible you see was cool beans and dressed so you might find out the abuse that this bit of those who are being is there not only takes a long time for beings to go to a world group and so use a lot of gas if you're doing 9 cooking mainboard sabean's. the mathematician resorts to a simple yet effective trick he combines being samples from different parts of all the beings in this sample pool are good you no longer has to test each part individual he only has to perform additional tests if there are better beans in the sample the more. the principle can be applied anywhere you can create

groups for testing that's why it can also be used to combat covert 19. in rwanda sets of 10 and 20 samples are combined and tested simultaneously. if the pull test result is negative all the subjects in the pooled sample are declared as not having coded 19. if the pooled result is positive then each sample is retested individual. the advantages of the pulling out portions just to reduce the cost spend to the for the adults to do the turnaround time for the vote for results and also to test the massively in the community also the group does. which are that course run for the community so

those are the men advantages for these. but if the virus has spread dramatically pulled samples test positive too often and retesting becomes costly and time consuming so far however africa has low numbers of cases compared to western countries and the method is proving useful there this is really hurtful for african countries but not only african countries even for the roping countries since we do love this and the published. pulling up close tonight a paper out so we have been approached by similar countries. ghana and kenya are now applying the strategy to group testing enquiries have also come from the us and the university of edinburgh scotland is using the method to test its students the method actually originated in 1903 american economist and researcher robert dorfman was the 1st to develop tool tests to screen u.s. army soldiers more efficiently for syphilis since then the strategy has been

further developed and is also used to test for other sexually transmitted diseases malaria and blood banking there's a lot of interest in this approach i think it's it's a no brainer we need to be. optimizing the use of resources. to develop the method the cameroonian collaborated with his rwandan colleague tessa and a.m.'s founder neal to rock it's a pan african response to the continent's challenges. it's really extraordinary that you can write on the board so many questions and no tell you how. this is so spread in a population how what happens when you draw a ball. out what happens to castle computers work so all of these are my motives on the. resort of people just investigating doing

analysis trying to understand better how things are around and work. the a ins network places great value one training young scientists across the continent they are confident that the next albert einstein will come from africa training young people to how to obvious knowledge and this ability to smarts to solve problems is wonderful and i'm very proud to be associated with this vision to be helping to drive it forward. book of it dawned on me for example as the rim proof that this is vital thing to do. did you know that p.c.r. technology which detects. virus is the basis for many other tests. it's used to amplify specific d.n.a. regions such can be analyzed. d.c. also produce

a breakthrough in forensic technology many possible to reach and this information from the smallest human traces this genetic fingerprint can be invaluable information at the scene for crimes. on t.v. shows solving crimes always look so easy clues. however tiny are soon analyzed and lead directly to the perpetrator. in real life things often look quite different. this is the state police forensic science institute in kiel normally crime scene technicians go to a crime scene this time it's come to them to get a scoop if the photographer could come in with us to take a few pictures of the crime scene that will make it easier for us afterwards to. the 1st step is to look for fingerprints cupboards have been ripped open the interior is a mess it looks like someone has ransacked the mobile home. under the table there's

a knife with a bloody blade. everything has to be documented and photographed where it's found later it will be studied in a lab. a crime weapon but no victim whose blood is it. what investigators do what a crime scene is gather evidence as much as possible. even things that look irrelevant can prove to be extremely important. person in by what we found a small piece of paper on the floor between the front say it's a candy wrapper. we secured it because it doesn't look like it belongs here it looks more like it might have fallen out of a pocket and under the table we found a knife that appears to have traces of blood so the knife is of interest not only for fingerprinting but also for d.n.a. analysis and possibly for any fibers sticking to it as well you would have floated

awfully fast. there's a fingerprint on the candy wrapper but it's faint and incomplete this clue would once have been impossible to analyze today however it can be enhanced by a process called sputtering. the wrapper is exposed to vaporized silver in a sputtering coat or. the silver condenses on the wrapper highlighting the fingerprint the technique was developed here at this institute just a few years ago. a photograph of the fingerprint is then digitally enhanced it's now so detailed even sweat pours can be seen as tiny white dots on the lines of the print. there is indeed a fingerprint here right above the lettering that means the spattering has performed a small miracle by coating the wrapper in silver the fingerprint is raised against the background and we can see it more clearly. i think we should apply the tape to the back of the sate. meanwhile fiber specialists have

taken over the crime scene. former as we have to secure the evidence wherever there might be any fire that's of course we try to imagine where the pepper trader was and have a crime was carried out that's our main focus but in principle we have to secure everything because we can never really imagine exactly what happened. and we just have to. even the slightest contact with our poll story is another to transfer fibers garments shed fibers all the time the nearby improve on have if the 2 of us were wearing pullovers and i hugged her or we rubbed against each other on the bus my fibers would get on her and hers would get on me and. everybody carries a distinct a mix of fibers around with them mostly fluff from their own clothes. fibers from

a crime scene can't lead to the perpetrator by themselves crime scene technicians also need to compare them with the clothes of a suspect. then they can tell whether or not it's fibers match ones from the crime scene. this involves picking out relevant fibers among those. of others. pretty much the 1st thing i do is look at all the colors through the microscope magnified say $250.00 times i look at both the colors in the shapes of the individual fibers to say if it's them or not and i'm like a bloodhound on the lookout for a single fiber in this case family looking closely at the red ones i mentally block out the other is otherwise i'd go crazy wasn't really fun and. once the visible clues have been identified and analyzed it's the turn of the

invisible ones the expert in invisible clues needs breathing equipment and total darkness. the chemical he sprays lights up for a few seconds wherever it's in contact with traces of blood hand prints appears next to the door and smears of blood along the side of the vehicle. he's going to go through it all of the evidence here is compatible with a person exiting the mobile home and moving perhaps injured unsteady on his or her feet and finding support along the side of the vehicle this is the victim of. deterrence out things are not what they appear the police officer had left the wrapper in the mobile home and the fingerprint was hers. the fibers were indeed from that red pullover but it belongs to a colleague in the lab. and the blood on the knife came from the butchers around the corner so there was no crime it was a dummy run at

a training exercise an internal police matter still the perpetrators are making a getaway taking the scene of the crime with them. for almost 200 years now photographs have captured fleece you know with originally in black and white. soon it became possible to duplicate photos using a negative to make more prints each point of light became a dot and the image a lot of data to capture moments. a lot photos things with time but what about digital photos although i can from ghana had a question about. how long can data be stored. humans have recorded their languages and their knowledge in the form of drawings and symbols since prehistoric times. on the analogue data carriers from back then play tablets or stones much of the information survived for thousands of years. as

a result these ancient data carriers can be read and decoded today. modern storage devices can carry a lot more data even though there are a lot smaller. but the lifespan of most c.d.'s and d.v.d.'s is estimated at less than 100 years. data that stored on the kind of huge servers operated by large companies should theoretically last forever as long as the days is repeatedly copied and as long as defective hard drives are replaced. in order to keep the ever increasing amounts of data under control researchers are developing smaller and smaller storage devices in the future synthetic d.n.a. could replace conventional data carriers. these artificially generated genetic

strands would have more than a 1000000 times the capacity of modern hard drives. on the reconstruction of neanderthal d.n.a. has shown the d.n.a. molecules are still legible after thousands of years. another method of storing data in courts is 5 d. technology uses namo lasers to write information into 5 dimensional fused. mind boggling speech. these glass just the size of coins can store up to 360 terabytes. and they last a very long time to turn teen point 8000000000 years. whether or not there's someone in 13800000000 years who can read the data is another question. $0.59 or binds the $59.00 with $21.00 zeros that is a lot of data and it's the amount estimated to have been created captured and

consumed by the end of 2020. in the next 4 years the amount is forecast to almost triple. in order to preserve the information it has to be constantly copied and uploaded onto new data carriers plus anyone can get in on the act of producing more and more data. for example it's estimated that in 2020 over a trillion digital photos were taken. data that is meant to capture memory as. we asked our viewers what data would you save for ever and how. cool rides your wedding day the moment of birth and anything to do with love so how romantic. it says here is a little more pragmatic we should preserve our knowledge of metal working as well

as plants and seeds on a floppy disk in order to ensure food security in the future. mohamed recommends internal rather than external storage writing i want to store everything in my brain we tend to lose the ability to remember things as we age hopefully in the near future we'll be able to upload data to our brain. finally randy writes he's most interested in saving images thousands of family photos and videos from birth to wedding to grandchildren in his case 50 years or 28 terabytes intentional thanks for getting in touch. a snapshot can only capture so much of a person but these days it's possible to bring old photographs back to life all of a sudden subjects can with their heads blink. uncanny even if it doesn't look quite natural. lets a new scientist marie curie is among those who have been given this kind of

treatment in her case there's no doubt that this video isn't authentic with people who are still alive telling real from fake can be more challenging. these days all it takes is one photograph to create a fake video in no time at all that's pretty impressive. with the help of artificial intelligence research is can now bring any photo to life in under 3 minutes manipulating the image remotely. 'd these examples took just a few minutes to put together and they show what this technology is already capable of. 'd team of specialists chiefly working on ways to automatically identify deep fakes like these these detectors will be crucial in the future. also the fake detectors are not going to be perfect but they will be able to detect the majority

of the deep content that is going to be distributed and in many cases this is good and what is important that these solutions have to be done in such a way that they can reinvent themselves and evolve as the technology for the pricks evolve. deep or fake so also an issue in be. it's becoming increasingly important to track down fake images in cases of insurance fraud for example. image analysts are researching ways to spot the markers of a phony image. intelligent image recognition software has fed countless fake images and videos and learns how to recognize anomalies. soon as clear markers are detected a red box indicates that something has been manipulated. if you look at the pic technology 6 months ago a lot of the video was very very easy to detect they were distorted you could

immediately see there's something wrong with if you look at them today they are at the verge of becoming very believable is becoming more and more difficult to detect whether a video is fake or not. it's a matter of 3 to 9 months before 99 percent of people when they watch fake video they wouldn't know that it is fake a bleak prospect or fact checkers fortunately fact checking company made me come it doesn't yet encountered deep fakes every day but without new detection tools expert is pessimistic. i'm often on food it's my hope for the future is that as more deep fake technology emerges the people tracking the fakes will have better tools to recognize the fix. because so much misinformation is spread so fast on social media users will have to raise their game using the fact checkers golden rules i'm

functioning as i firstly does oneself and i have to know myself in the media i consume that's very important. if you fall for something from a media source that you trust deeply then it becomes difficult next just to see who's writing where something comes from so you need to master search engines clearly. i need to know how search engines work and be able to do comparative searches on top of that of course is the search for images so-called reverse image search finally speed up the rate of information consumption and if something sounds overdramatic then maybe it's better to ask people who know about us or to bypass when using time and our skin but that alone is not enough more education is also needed. to be at us and of course we want something to happen in the schools now comes the big bucks are always shouting that schools need to do something yet we're saying that there's so much fake news on facebook this is a problem young people are not on facebook. it's

a $35.00 to $55.00 generation and now we've identified the core of the problems and we're not doing enough educational outreach to adults. ok let's give it a go what do you make of this video it was lightning striking a train track well it's a fake pay close attention to the trajectory of the flash it should really have some burn marks in its wake but there's not a trace also the camera operator is way too calm and steady. but there's also a clue in the title of the video here c.t. computed generated images clearly faked. some also branded this video with a woman doing a reading in the middle of the military takeover in myanmar. so what do you reckon or is it real or fake.

i'm just shadows seem to suggest it's a fake they seem very truncated buns if you look more closely you'll see that there are steps behind her this supposed to be located at the royal lotus roundabout in myanmar and comparing the image to that in the video reveals the markings on the ground the street the flower pots are identical in the video the silver posts must have been installed since the google image was recorded in 2018 so the location appears plausible and the shadows of the downs and that of the cars match up. the lighting is the same so this video is no fake. because what is red white i'm glad i'm leaving you. do you have a science question you'd like us to answer. send it in as a video text ovoid snail if we featured on the show you'll get

activists press on with protests despite a weekend of deadly violence there's been international condemnation following sunday's army violence in young god meanwhile the military has imposed martial law in parts of the city. where a large thank you very much for your company what we begin this broadcast with breaking developments germany france and italy have suspended the rollout of the astra zeneca covert 1000 vaccine over safety fears but beriah denmark ireland the netherlands norway and iceland already stopped giving a shot following reports of an increased risk of blood clots but astra zeneca and the world health organization insist there is no risk the move comes after a leading german lawmaker called on the authorities to issue clear guidance on

whether the vaccine is quote good or bad and german the health minister yes sponsored an investigation was being launched. as for tone and an initiative to keep up confidence in this vaccine we now have to give our experts in germany and the european union time to review this recent cases they must also clarify the question of whether the benefits of pex in nations continue to outweigh possible risks because one thing is clear non-blacks a nation also has serious health implications and that review process is what we're waiting on now but in the it's. a moments ago i spoke to a star. he's a very raleigh just an associate professor at northumbria university in the u.k. and i began by asking him why a number of countries suspended at the use of the astros at seneca back scene yet the company says there is no evidence that it causes an increased risk of blood

clots. so i think we must say 1st of all it's extremely important right in situations like this of ours to take them very seriously have a look at potatoes very carefully before jumping to conclusions. we've come into this pandemic through decades of people listening to conspiracy theories around the risks of vaccine space because to other diseases so any kind of wrong message it's actually going to be very impactful especially in an effort to try and push back against this bill so it's really really important that we give clear concise a trifle the top messages so in that respect i fully support the decision of any law to stop of a look i'll take into consideration the data now on the data what we know is that 17000000 people of received this boxing and 37 people have developed

this plot points or not corresponds to point 0002 percent. of actually anybody that has been vaccinated getting a blood clot and you would probably agree with me that the risk of getting a blood clot is actually a 100 times if not more less than the risk of actually dying from corner virus if you get to get it done for 2 to basically be afraid of something that may happen because of the boxing in order to protect yourself from something else that can be much more harmful to your alone decided to people well a lot to take the bus and share with us and some of the experience that the u.k. has had with this particular inoculation. well can i say obviously many people would have preferred to receive one of the vaccines to have a generally slightly higher percentage of afic a c.

but it still is a very efficacious fox and we have other vaccines that are being approved for decades that are nowhere near as acacias us this foxy and as a result of thought. there should be no to no hesitancy about receiving the percentage collection the only division start. who should be a bit more careful of the people with very strong ologies and this is just something general for all medications i'm sure at last time you went to the doctors and they gave you a prescription they asked you are you allergic to anything so if you are allergic to something you need to tell the doctor before you get any boxing just this boxing or you know there are iraq says it's actually important that we think about the common good and how we can work as individuals to support society in the economy in general. and that was just a stereo some of us from northumbria university in the u.k. speaking to us earlier let's get some other developments now on the pandemic the developers of russia's sputnik v vaccine say companies in germany france italy and

spain have agreed to help produce the job it hasn't officially been approved in the e.u. yet though and i see you doctors here in germany are urging an immediate return to a partial lockdown because of covert $1000.00 nutation germany has seen a rise in infectious is gradually easing measures late last month and half of italy's regions have gone into a strict lockdown it's because of a new spike in corona virus infections authorities say hospital admissions are beyond what they can manage. and bring up to speed with some of the other stories making news around the world the european union has said it will take legal action against the u.k. government after it announced it will unilaterally extent the grace period for brags that the e.u. says london's decision to delay imposing customs checks on food deliveries to northern ireland amounts to a violation of the northern ireland protocol. opposition activist and

musician bobby wine was arrested on monday during a protest in the ugandan capital kampala why it was leading a rally against the detention of his supporters when he was seized by the authorities mr wine is now reported to be under guard at his home. voters here in germany have handed chancellor merkel's ruling conservatives a stinging defeat in 2 regional elections on sunday voters in the states of bonn burton berg and the and ryan land latin it turned their backs on the c.d.u. in record numbers say leading cd u m e p m p will give us his take on the elections in just a moment but 1st we have this report. germany's super election year began badly for chancellor merkel's conservatives in 2 regional elections they significantly lost support among voters the c.d.u.

is in crisis one day later in berlin the frustration was crystal clear among the party leadership is of a clip when we can clearly say that the regional election results are disappointing for the cd you shouldn't invite any election result is always a wake up call anyone who doesn't take note of the election results who simply ignores them is simply not understood the meaning of an election. the c.d.u. was probably punished by voters for the painfully slow coronavirus vaccine rollout nationwide. a facemask procurement scandal involving conservative lawmakers only made things worse but one party's loss is another party's game after winning the election in the wealthy state of botton britain burke the greens were in triumphant mode on monday in overall we see that momentum for the greens continues we're starting the super election year strongly. the trend of recent years is also being borne out in 2021. and it's fun says similarly the social democrats

were eager to highlight their victory in the state of ryan learned that tonight. the election result especially in rhineland poll out tonight is giving a goose to the social democratic party as a whole and then we want to use the upswing to help ensure that we can lead a future federal government and provide the german chancellor. thought some chance the 2 original votes are not necessarily a preview of what will happen in september when all germans go to the polls but they do provide clues about what voters throughout the country want what problems they see what parties they like and about what coalitions might be possible at a federal level for the c.d.u. in particular they're also a stark warning they have 6 months to recover before their biggest challenge whether they can hold on to power without on the america. i mean our security

forces have again fired on pro-democracy protesters killing at least 5 people according to media and eyewitnesses the fatalities come a day after dozens of activists were shot dead in the country's largest city of yangon the same broadcaster says the military has now imposed martial law on 6 districts in the city the u.n. special envoy for me and maher called for international solidarity with protesters . was deadly clashes continued into the night as fires burned in the streets and smoke mixed with tear gas. on the monitor group's report that over 40 people died from sunday into monday morning the bloodiest day of protests against the coup so far. on the outskirts of yangon unidentified attackers set fire to chinese own factories reportedly wounding multiple employees many pro-democracy protesters accuse china of secretly

supporting 2 leaders. the chinese embassy in myanmar issued a statement saying china urges me and mark to take further effective measures to stop all acts of violence punish the perpetrators in accordance with the law and ensure the safety of life and property of chinese companies and personnel in myanmar. me on mars military shows no signs of easing the crackdowns the military declared martial law and several large districts of yangon and mandalay the country's 2 largest cities but protesters are not relenting in mandalay hundreds return to the streets on monday morning to call for the release of aung san suu kyi and other civilian leaders arrested at the start of the coup. a court hearing was scheduled for sujit today but her lawyer reported it was postponed me and mars deposed leader is now expecting her next hearing on march 24th. i want to cross over now to journalist andrew nacro son in yangon and you give us a sense of the people who are out there on the streets risking their very lives at

the moment who are they. the people who are still left protesting are kind of the most hard core group in the 1st month before 'd police started using violence against protesters you had people of all ages and all backgrounds participating in the protests now are increasingly seeing it kind of down to mostly young people a lot of garment workers and laborers who are continuing to lead and really diehard activists and diehard and all these supporters and there are reports that protesters are attacking chinese owned businesses what more can you tell us about this. there's still a lot of confusion surrounding this what i will say is we've seen every indication that protesters did attack chinese companies in the days leading up

to yesterday's protest garment workers and protesters and high profile activists were saying if anybody is killed in the i'm tired we will burn chinese factories to the ground people were killed in law and chinese factories were set on fire so it seems like that's what happens and why are they targeting chinese businesses. where there's a kind of range with the indians i think some protesters believe that china secretly supported the crew in the military government i think that's unlikely just because china likes political stability had a lot of projects agreed with aung san suu kyi probably like dealing with aung san suu kyi because she is rational and logical on the other side i do think that protestors have a legitimate grievance with the way that china has kind of refused to condemn the 2 kind of play both sides and not take an active role so i think that they're you know it's fair for them to be upset and expect more from china and you i mentioned

you referenced the civilian leader in san suu kyi hearing was supposed to take place a today it has been adjourned what more can you tell us about that. so we were told that the year it was delayed due to technical difficulties. caught all go by all day today but obviously we're still able to communicate over wife ice and we're not totally sure why that happens the hearing has been delayed she's been accused of corruption but not formally charged with corruption specifically she's facing a few other charges so i think it's likely once they hear us get going again she'll get hit formally with corruption charges journalist and june ackerson that reporting from yangon i mean mark thank you. thanks and before i let you go reminder of the top story that we're tracking for you this hour germany italy and france have joined a growing at a list of countries in suspending the use of astra zeneca corona virus vaccine over

concern it could cause blood clots astra zeneca and the world health organization insist that the vaccine is safe. stick with us stephen bird's weight is up next with a new business news outlet like rock n roll and i'll see you again at the top of the out. a little guys this is the 77 percent of the platform offered to super tuesday issues this year i guess. you know for this shutdown we are not captioned delicate topic africa's population is growing.

and young people clearly have the phoenicians the new job. is 77 percent. on d w o. germany france and italy join the poles on astra zeneca is vaccine raising pressure on regulators to determine if the safety concerns surrounding the job are merited broad health officials so far stand by the vaccine. also on the show industry's decarbonising and money is flowing into the rare earth metals industry critical for batteries look at that what that could mean for african economies. and as if it's grown a pet growth of our spend demick wasn't rattling supply chains enough the african

swine fever is doing a major blow to pig farmers. who are welcome to do business i'm seen beardsley in berlin it's good have you with us france italy and germany have joined the growing list of countries putting a general pause on the distribution of astra zeneca vaccine further complicating global vaccination plans their decisions follow reports of blood clots in some patients the dutch organization tasked with reporting adverse reactions says it's received 10 reports of incidents after vaccinations with astra zeneca the world health organization the e.u.'s medicines regulator and the maker of the jap all insist it is safe and this is the latest controversy for astra zeneca which has repeatedly failed to meet its vaccines liveries target. now here's our correspondent frankfurt conrad who isn't. statement to the press astra zeneca has said and the ellis' of the safety data of more than 10000000 records has shown no evidence of an increased risk of palm unary embolism or deep vein thrombosis in any

defined age group batch or any of the countries where the vaccination has happened and this is backed by the health authorities both the w age or the world health organization or so the european authority him are saying that they don't see any connection between the vaccinations and the blood clots no direct connection no causal connection but of course on the other hand everyone wants to be super careful and that's why they put the application on hold office vaccinations in those countries that you told us about. in our correspondent frank for their wealth let's take a look now at some of the other global business stories making headlines. germany's id t.v. logon to will produce the single dose johnson and johnson corona virus vaccine over the next 3 months the vaccine received conditional approval for use in europe last
