Transmits the dangerous Infectious Disease malaria. One bites and the parasite has entered the bloodstream it invades the red blood cells causing high fever and anemia then only medication can help but not every fever is caused by malaria. Wrestling this baby has a fever and dr valerie document will treat it at this Outpatient Clinic in dar es salaam. Only but there are very few diagnostic tools here when a child has a fever its immediately given antibiotics ninety percent of children leave this clinic with antibiotics that shoots. Docomo says many dont need antibiotics shes developed new diagnostic procedures involving quick blood tests and special software for the lab as in Research Using blood samples we identified a range of causes of fever and other than malaria and with the data we developed algorithm a flow chart to guy clinicians through a consultation. Its available as an app on a tablet computer and helps with diagnosis and therapy options that have let you have the Program Shows which tests to conduct in a certain situation seven you enter the test results and the tablet shows which course of treatment makes sense. Not proceed as you know through her research dr moore has established that cases of fever in children here are often caused not by bacterial protozoa as is the case with malaria but by viruses it doesnt make sense to treat them with antibiotics or anti malarial agents. These findings a very important antibiotics are overprescribed in countries across africa and that promotes antibiotic resistance which is a major problem worldwide that commands work has already drastically reduced their use in tanzania she lived here for three years and still comes back often. They still read it they move on stuff where cancers where my work really shows results after a few months in switzerland it all starts feeling a bit abstract so its very important for me to return here regularly so that i know why i get up in the morning. Valerie moore is always on the move she doesnt worry about the distance between tanzania and the swiss tropical and Public Health institutes impossible where she works with blood samples from africa are examined here for one main reason. Say do we want to understand how many patients have malaria and how severe it is thats the only way to really know if thats whats causing their fever you know back home or is enthusiastic about developing faster blood tests the goal is to be able to make precise diagnoses with just a single drop of blood to then apply medications in a more targeted manner. Sympatico this is a small revolution and quite simple it will mean a complete change in how we treat patients in africa thats the whole point of these experiments explains. She always has the people of africa in mind when conducting her research. Feels very attached to tanzania its a time where for me every time i come back is the fulfillment of a childhood dream of the. First at eight thirty and we present at night. As a busy schedule so shes worked with colleagues in africa for more than ten years and is highly regarded. Of that most that you can assess a fair bright child in less than ten minutes this is the minimum that you need but remember its also starting to make use of her findings and her algorithm can see this on a very respected because we listen to people and have a working hand in hand with them feel years. Have researched aims to optimize patient care in dar es salaam. In los suns switzerland also works always equipped with a top it with yes its my mobile office i work everywhere on trains under a tree in africa everywhere. On that one that care back to. The University Hospital and those on she vaccinate patients travelling abroad. Lakhs. Who picked. So so for question if. I get paid to take care of swiss travelers heading to the tropics. There isnt going to help one who doesnt of course theres sometimes people here refuse vaccination they dont realize how lucky they are because in africa people desperately need vaccinations. Calorie dot com or is committed to improving health care in tanzania and optimizing the use of antibiotics preventing that over use with all its risks and dangers. If the key to future success lies in a countrys young people then africa has a lot of potential around sixty percent of the people on the continent are under the age of twenty five and theyre all demanding the latest Digital Innovations deliverable straight to the smartphone thats a huge opportunity for startups there the next report from uganda shows how africans are developing solutions to african problems. These inventors in kampala uganda have developed a very interesting new device theyve called it. A testament leiria using a light sensor and a smartphone and without taking blood. We narrowed down to maria because it was one of a visitor all of us have the best we have of all of what about malaria before and we wanted to quit a solution to something we have a million and we said it to no call it we could improve it and and then we target it to make it in one even if the process just for malaria the inventor spent four years developing the matty value system now the device is ready for Clinical Trials they say it delivers an accurate diagnosis within just two minutes. Whats more its entirely noninvasive no needles are needed. This is how matty baboo works an infrared light sensor inside a finger clamp looks at red blood cells if the cells are infected with malaria their shape color and concentrations of different. Data is transferred to the after the smartphone which detects those changes the diagnosis then appears on the display. Is much faster than the standard microscope method which takes at least fifteen minutes for one single test. For many years the World Health Organization reported steady gains in the fight against malaria but now the u. N. Agency says progress the stalled in part because of a lack of funding. Quick cheap and reusable tests such as marty barr who could make a significant difference. More than three million patient applications were filed in a single year in twenty sixteen thats a record humans have always been inventive but what was the most important invention ever thats what we asked you on facebook. Cases higuera believes its agriculture because thanks to that city is formed and empires were built and will needed to feed our growing population. Service dimitrius thinks is this an accelerator because it will eventually help humanity to understand god. All of the gama says the greatest human invention is language because it made us aware of ourselves and to this day theres been no greater power than the word. And im going to show up says its the internet and the computer because all the information is now just a click away. She says children are so smart. Because they can discover answers for everything. Thanks for those comments. Books you missed it. Looks like you need a little more practice digitalization has even become a topic that affects our pets. Internet companies are constantly evolving to keep us humans captivated with new features and updates. But where do you draw the line between normal computer usage and detection. Its break time for these High School Students a time to check the latest photos and videos on their phones via the likes of snap chat and instagram like you know thats what generation is me just social media have become hugely important even for little kids we dont want to miss out on anything i mean. I spend three or four hours a day on social media so its a big factor. Only has twenty four hours and if youre asleep for eight of them well half the day is already gone so whats the social media is currently a major issue on us chat shows two in february a group of former facebook and google employees launched a campaign to combat the manipulation of young people by the very companies theyve helped build. This is game over unless we change course really genuinely i one hundred percent believe that because youre going to do you really think this is a nexus like i absolutely believe that this is not for fun this is not because writing a book or selling this is like you dont want an extraction based economy powered by playing chess against peoples minds winning because it will bring a knife to a space laser fight the truth about Tech Campaign aims to Pressure Tech giants into making less addictive products. Story and check and share and watch videos and funny again like Everything Else on social media that makes it so stories or. Gives snapshot there like the group are also creating ads targeting schools in the u. S. Educating students and parents about the detrimental effects of technology they hope to initiate a nationwide debate on the issue. A campaign has a budget of seven Million Dollars with a partner sponsoring fifty Million Dollars worth of Media Coverage and time because the people behind the campaign were themselves once programmers and developers for facebook and google they know how the companies and their products work. Behind the other side of the screen when youre using it theres one hundred engineers whose entire job not because theyre evil but their job is to figure out how do i keep you coming back to the public so you two wants to auto play the next video snap chat wants to put the number of days in a row in something called the streak next to every Single Person in your kids contacts they say if youve got thirty friends they say heres the number of days in a row youve spent youve sent a message to each friend and it keeps each of them. Snap chat streak feature is evidently having the desired effect. But its really important for some people i know when the streak is about to end an hour glass appears and the other person calls up to say hey send me a snap we cant break our streak. For long. I had that just yesterday i got a call while i was at my internship placement and she writes hello she called me twice i think when i asked what was up she said i had to get snapping the glass is almost empty i thought oh well its a familiar story for professor ross more and more young people are seeking his help they feel they have lost control over their social media activities. Companies are clearly going to introduce triggers among children and young people in order to keep them on social media and online networks. And. So i welcome those in the us who are now saying that social Network Providers essentially have an enormous responsibility when it comes to the protection of minors. Id like to see more high profile individuals doing the same in germany too. In march he published new figures on social media usage among teenagers two point six percent of those surveyed have. A social media disorder in absolute figures that translates into one hundred thousand young people across germany but surely two point six percent is a tiny fraction as it is on that that figure refers to those worst affected and the ones who meet the criteria for addiction. But theyre only the tip of the iceberg of an iceberg that will broaden its basic stream lee quickly and below those two point six percent or a considerable number of youngsters here use excessive use of social media does cause problems. To muslims is convinced that social media addiction is a phenomenon that will pose immense challenges to society in the future. I dont want to be a fearmonger but im fairly sure that there is a gigantic tsunami approaching. Of. We are currently still at an early stage so theres still a chance of proper prevention i way of new regulations but we have to use that chance. To get into its important for people to come together to talk about what action to take on a permanent ongoing basis the a society has to talk about how we want the internet and social media to be structured has to take place both at school and at home and of course teachers have to be involved to. Media literacy does in fact feature on the curriculum at this high school in hamburg theres even a social Media Advisor starting in fifth grade pupils learn to reflect on their social media use and to see providers in a critical light. Was fun they all have a big responsibility because they run the whole thing but i dont see them taking action because that goes against the essence of their business and the source of their profits. They dont care if there are a few hundred thousand kids addicted. Because thats how they are in all their billions. We contacted google and facebook to talk about the dangers of social media for young people but they didnt provide answers to our questions. Some people cant stand the sight of it. For others its just a part of their job. You use too much of it and the life will drain from your body the only thing that can save you is a fresh supply. Peter abraham from a blue joe wants to know. Why animal blood cant be used for human blood transfusions. Thats a good question human blood supplies are not always readily available but theyre essential for surgery and Cancer Treatment for example. So why couldnt we use a sheep blood if the animal was being slaughtered anyway. Up until the Nineteenth Century repeated attempts were made to do just that usually with fatal consequences for man and beast. The reason the blood of animals and humans is not compatible like us all mammals have different blood groups. Sheep have more than twenty. And horses have as many as thirty four. But theyre completely different blood groups than the human ones. A a b. B. And o. If blood groups arent compatible it can trigger dangerous immune responses during transfusion even if the donor is human. So what about chimpanzees human and chimp d. N. A. Is very similar almost all champs have blood type so theoretically they could donate blood to humans with the same type theoretically at least. But their blood contains different antigens that would be detected as foreign proteins by the recipient causing the immune system to reject the donated blood a reaction that could prove fatal. If you have a science query you can submit it on our website if we answer it on the show youll get our d. V. D. Featuring a lighthearted look at albert einsteins most famous theories. The most important thing is to never stop asking questions. Up and away as the horizon retreats the sky is clear for miles at least today it still is and most places but engineers and Developers Say that wont be for much longer. They expect a lot more transport activity to move into the air soon some of it aint saving lives. Just a few more minutes until the stress test begins denis global and his team have been working towards this moment for years the aim is to transport lifesaving blood supplies by drone much faster than by car through a crowded city. To say fifty or sixty times a year we need blood fast every minute counts and thats where drones could be used or. That fifty to sixty emergencies in the two hospitals in frankfurt where goble words deliveries often get delayed traffic in the city has increased enormously over the past few years it can take up to an hour for a courier to get blood products from the blood bank in the one hospital to the other instead of twenty minutes when there is no traffic. Its a challenge for martin flesh who runs a blood delivery service. Drivers are experienced like you know the best routes and short cuts they get traffic updates on the mobile phones and so they can try to avoid jams if need be. By drone the blood could be rushed from the one campus to the other in just ten minutes travelling at up to sixty kilometers an hour no matter what the traffic or the time of day. That may sound very practical but in germany drones arent allowed to just fly around in built up areas Unmanned Aerial Vehicles abound from flying over crowds of people. Meaning the in the city and parks and no drone zones. Drones have to maintain a distance of at least one hundred meters from highways hospitals and railway lines. So an aerial blood Delivery System would have to get special permission first. Encounter the nomic basically getting permission has been the biggest problem so far in the middle east we need a permit that doesnt have to be renewed all the time from if were helping our stress tests will convince the authorities to grant us one. Side. The drone completes its first test flight and lands exactly where its meant to without any further involvement from the operator. Its not just City Hospitals that would benefit from such speedy deliveries many smaller hospitals and clinics only keep enough blood products on site for one average day but if theres an emergency if complications arise during surgery or if a patient has a rare blood type further supplies have to be obtained from a blood bank that costs time and thats when drug. Could provide a solution. That. Blood is not only a precious commodity its also sensitive it has to be kept at the right temperature. And theres a sensor in the container so we can monitor the temperature of blood products during a flight those concerts were off. But what if a drone like this were to land in the wrong hands a special lock ensures that no an authorised person can access the blood. The moment we box when the container is attached to the drone the system recognizes that its there and the radio control servo locks it in place then its totally secure and cant be opened from outside. Or of. Only the recipient can unlock the security mechanism the drone cost around one hundred thousand euros to develop much of that went into ensuring safety if its battery is almost empty the drone uses it residual power to slowly descend to an altitude of two to five metres and hovers where it is until it can be located with its built in g. P. S. Transmitter and picked up. The second part of the stress test the drone have to transport two liters of blood on the prescribed route in less than ten minutes. But dr girl is already thinking ahead deliveries might just be the beginning. Their home feeling a lot of smaller hospitals cant afford to keep a laboratory open on the weekends or at night but their lab samples could be sent to larger central facilities for analysis or skill so the same goes for intra operative biopsies tissue samples taken during surgery that have to be analyzed by a pathologist. Some hospitals dont have a pathologist on staff so it would make sense to send out the samples for swift analysis. But also to put it on the lucy of those. Lets the nine minutes later the drone makes a
