and political and social topics considered from different perspectives. we cover the issues that turkey make up for for information. connect to an unbiased agenda subscribed no want you to. get into tomorrow today the science show on d w. coming up. the 10 percent myth do we really use only a fraction of our brain. big data needs big brother in china's social credit system. and look at change the technology and its potential benefits. in

2030 british man named james howells accidentally threw away his hard drive it had 7500 foot coins stored on it too bad for him because that amount of the crypto currency is worth millions today how else trying to find the hard drive in a landfill inveighing. bitcoin is based on blocked chain technology and nowadays the digital money is being mined in a very remote place. the northfield on norway's western coast is home to an abandoned mine which contains $29.00 kilometers of paved tunnels 5 levels deep. this is where the left out data center was built. inside these containers hundreds of supercomputers hummel what you're around the clock they're also mining pit coins together with. other computers all over the world these super computers form the

backbone of a gigantic database of blocked change. in items such comments are can block to block the shame is the driving force behind the next generation of the internet it's often called the web 3 or the decentralized web web 3 can be hard to explain because it doesn't change the internet as such. it just reinvent status structures and gives us greater transparency with respect to what happens to our data about. a book chain is a decentralized database or digital ledger identical copies of the sludge are stored on tens of thousands of computers in the network. when someone carries out a transaction it appears in every copy of the ledger. information about the transaction is written to the block chain which is designed to be immutable the

transaction log can't be changed after the fact. if anyone tries to modify the data blog that's visible in every copy of the ledger. and any participant can check it at any time. change technology is designed to be secure transparent and tamper proof. of the history if you don't change began with bitcoin. these days crypto currency such as pick quine ripple and ether are accepted as payment in many shops and restaurants. and on yeah things of every transaction is stored by every computer in the network in an encrypted data block and then link to the chain. none of this requires a bank which is why crypto currency and block chain technology could help break up the banking monopoly. but not all crypto currency is based. in technology.

here in this technology park in 08 the small containers company uses block chain technology to help transport pharmaceutical products the company has developed special temperature controlled element in containers that can monitor themselves that's important because fluctuations in temperature can damage some medications change could help simplify and monitor such complex logistical processes and infested women complain we ship a container around the world for pharmaceutical companies that can entail the exchange of up to 200 documents between logistics firms freight brokers airlines and more at each exchange there's always the possibility something could go wrong that's where block chain comes into play the data is basically hung on a laundry line that every party has access to or they can access which relevant to their next step the most of those $200.00 interactions can be eliminated i mean you

know. well why it's the pharmaceutical industry spends $15000000000.00 a year on temperature controlled logistics. analysts believe that doctrine technology could muster if we lower costs by simplifying processes and reducing the workforce. gets in one day we'll have autonomous containers that will track themselves and know where their next client is it will use block chain to tell the logistics firm where it should be picked up and where it should be delivered across the containable independently travel the world it. one day the way we travel the world might also be transformed and simplified by the octane technology. that's a subsidy on more it's fun and his team have examined $120.00 different ways blocked change might be used in rail travel for example how a passenger could use several different modes of transport on a single ticket. and i imagine someone wants to go

from a to b. they might 1st travel by plane stay overnight in a hotel and use both local public transport and commuter rail and ride a bicycle these are all different entities from our competitors so they won't necessarily trust one another with chain can create conditions to allow them to trust each other so that they can generate an offer on a single ticket it will benefit everyone in the end words from bonynge shows how that might work using and developed by don't you by. someone who wants to buy a ticket opens the up and down he selects how many zones he wants to travel with say he's in mannheim and wants to travel across 2 zones and then this is the special part he can say he wants to take a taxi home to sort of you press a taxi and that's integrated into the journey state and particularly generator

that's valid for both the taxi and public transport you use the ticket is stored on the block chain which you can show to the taxi driver taxi if the driver uses a smartphone to scan the ticket and scandals ticket. their money it's going to the driver then checks with the block chain to make sure it's a ticket. as soon as the block chain confirms the validity of the taxi driver will receive his share of the ticket price. tickets too. until now competing providers like railway and taxi companies kept their distance from one another. as a transparent and tamper proof technology change could make it easier for competitors to collaborate. likes shares followers but those are the modern day currencies of social media whoever has lots of them must be good writers. we also trust digital ratings when you make

purchasing decisions you. hasn't been influenced by other people's revealing news. that's in china the government is taking that to a whole new and scary level. it's one of the most basic human needs going to the bathroom but can you imagine toilet paper being rationed and you pay for it by facial scan that way no $1.00 uses too much it sounds surreal but it's a reality in china a reality that makes it impossible for example to vanish in a crowd private life forget it. surveillance cameras are everywhere. big brother the state is watching all the time. and these days just watching isn't enough movements are tracked and faeces are scanned the chinese state is testing a national reputation system for its citizens known as the social credit system.

in the future with the system recalls dystopias like 984. people are under complete surveillance. complete the system is still in the testing phase at the moment. there are around 40 experimental locations around china some by 2020 the government plans to have the system up and running. for the government it's supposedly about improving society more morality and less corruption this is how the social credit system is designed to work. citizens are ranked according to a score which goes up or down depending on their behavior if someone plays too many computer games they are neglecting their family and damaging their health their score then goes down. social behavior finances media

use all. that is stored in a central database and there are consequences if you score too low your travel can be restricted banks won't give you loans and your child can be denied an education . companies also get a score the government hopes this will prevent food scandals or fraud for example. the problem is who would ever publicly challenge the system criticizing the government would make your score sink scientologist's cut your levy says blind obedience is nothing new in china. that's the stop he's adopted people don't seem to fit the state well if you use that data for social control. is actually a great deal of trust in the centralized government people think that if the state controls and collects the data it must be really good for society.

but is the chinese government really making its citizens morally better with its social credit system by collecting their data and i don't really boarding or punishing their behavior. and how far removed from such a system are countries outside of china that something that occupies psychologist get kicked of and so. so there is this but the big difference is that with does it's not the state that's involved in the must collection of data on creation of a social credit body on one thing. instead here at certain industries that are involved owns. the buyer. examples on facebook and instagram likes reflect popularity health insurance companies want to gather data from health apps and offer bonus systems as incentives car insurance companies can collect data via a black box and advertise with rewards for decent driving behavior the analog and

virtual worlds are increasingly merging and that has consequences. the people mentioned in the social credit system will transform people more than practically anything else in human history the mention. illegal will chase after the best score. that they might then become more moral from the point of view of the chinese government. they will become more conformist owned the system and the system will become more efficient. and now one can speculate how far the systems to which i call digital absolutism how far a democracy can withstand such a system. system geared towards improvement and the optimization of mankind but how truly human would mankind be and how worth living would life be if big brother and big data determined our everyday lives.

brit's of humans and machines are well known from science fiction like the violent hero of the 970 s. t.v. series the 6000000 dollar man. 2 days by a hackers have taken the dream of cyborgs one step closer to reality. hauser is a digital pioneer he's had microchips the size of a grain of sand implanted under his skin in each of his hands he has 3 chips embedded between his thumb and index fingers he doesn't like the term side he prefers to think of himself as a new species. i've upgraded so i did feels like i'm on a different level of development and. i don't mean that in the latest way or

anything but i do feel like something's different. he made a spontaneous decision to have his 1st chip implanted at a congress in desoto off on biohacking and self optimization through digital implants. 4 of our it was someone else's turn 1st so i was able to watch i would stun the needle didn't look any more threatening than the one when i donated blood it was just a little bit thicker. then more chips followed he says that all of them a safe from a medical pot. interview he even implanted the last one himself. one of the chips opens his office door. and other contains all his emergency data such as his blood type and his organ donor i.d. the uses in everyday life is still very rudimentary but that doesn't bother him more thoughtful i want to advance i want to move forward be a pioneer an early adopter of 1st mover i want to try out something so intensely

that i can better judge it toward. the 53 year old isn't concerned about data protection he's convinced that the m. plants are just as secure as bank cards or smart phones that work with similar technology from if you steal from me the much more crucial question is what are the possibilities and where are the risks of course it's sensible and reasonable to weigh both but my 1st question is how can it be used in the desert of nativism network and has lots of professional contact with startups he in the company he works for support young entrepreneurs for example by renting them offices he embraces the new and unconventional and he has a clear goal. maybe i can leave my key chain in my wallet at home some day maybe at some point bit by bit i won't need them any more strick for stroke. and till that day he wants to further explore the possibilities of digital implants and he's

already decided to have 2 more chips. estimates suggest that more than 10000 people worldwide have microchips implanted in their bodies. he asked on facebook if you would get a chip implanted under your skin. for the answer is definitely no he already feels under surveillance from his cell phone he says not every technological advance is beneficial. jenna says implants should only be for adults and he also worries that income. sharing could compromise privacy. congress is in favor of implants that improve people's lives but not if they used to watch over and govern us like androids ruben replies that governments monitor us in any case with or without implanted chips he says the fusion of man and machine is inevitable. we'll see if his right thanks for your comments. and

now from some optimizes to the well less optimized mishaps happen. sometimes we don't think things through. why is that your various theories but they are actually external factors that make us dumber than we have to be. may be avoided. is there really no cure for stupidity. don't worry we humans are pretty good at making the most of what we're born with. babies learn about the world around them at an unbelievably fast pace they 1st develop sensory motor intelligence learning to crawl and then to walk. then they begin to communicate and express what they want their intelligence grows completely

automatically if infants are stimulated and well cared for their brains will develop by themselves. but at one point that ends infants grow into adults and in some cases the intelligence pendulum swings back. not every annoying neighbor awful boss is necessarily unintelligent so what dumbs you down. basically all the factors we know to impair brain function one of them is alcohol germans for example drink the equivalent of 11 leaders of pure alcohol a year that's bad for the brain. heavy intoxication can't even trick your brain into seeing things that aren't there. smoking pot doesn't help either especially if you start young when your brain is still forming according to some studies regular use of cannabis can impair your intelligence. the effect is

supposedly less severe with older drug users. and you snooze you lose in activity doesn't boost intelligence we need to feed our brains with information without input our brains wither. the stress can also take its toll a cocktail of the stress hormones adrenaline and cords old can leave us feeling anxious and tense and during tests can even cause blackouts. but that's not all someone going through financial difficulty could also see it negatively affecting their intelligence according to researchers economic hardship can result in brain capacity poverty related troubles use up so much mental energy that less is available for other purposes it can translate to as many as 10 i.q. points. though that's not inevitable amazingly if financial problems go away

i.q. can go up. there are environmental toxins these too can adversely affect intelligence u.s. scientists have shown that exposure to certain environmental chemicals poses a risk during pregnancy and can impair fetal brain development even lipsticks soap and hairspray sometimes contain toxic plasticizers 2nd have a detrimental effect on prenatal development that's why certain classes are sizers are banned in baby choice. but ultimately. there's no cure for a small mind. the global burden of disease study says one out of 5 deaths worldwide is due to an unhealthy diet and caused by smoking on average daily meat consumption is higher than the recommended 23 grams. and we tend to eat much more salt than is good for us.

to eat far too little for 100 grams a day instead of the recommended 250 grams. and our consumption of nuts and seeds is also much lower than my traditional expert's advice. spain and france have the healthiest diets but does good nutrition make a small amount. several studies have shown that a nutritious breakfast improves concentration and helps children do better in school. a good choice for breakfast is muesli with fruit and dairy products. sweets are off the table though because they're broken down too quickly. overnight the brain clint's out waste products and in the morning it needs new energy in order to work efficiently throughout the day. another study recommends eating at

least one handful of berries every week. this could delay the slowing down of memory performance by some 2 and a half years. another study says berries and nuts along with a mediterranean diet are good for our brand mediterranean means lots of green leafy vegetables fish or chicken beans whole grain products an olive oil traditionally a glass of wine is part of the meal but few sweets fried foods or red meat studies suggest this diet could cut the risk of developing alzheimer's disease in half one possible explanation the older we get the more chronic inflammation there. tends to be in the brain. the idea is that the various nuts and mediterranean foods contain antioxidants that might reduce that inclination and slow down memory loss.

if outlet is red white i mean if i. see you have a size question that you've always wanted on say that we're happy to help out send it to us as a video text ovoid smell if we answer it on the show we'll send you a little surprise as a thank you can i just ask. you find as i did have a dot com stash science all drop us a line at e w underscore site tech on facebook d w dot science. this week's question comes from the rock how. do people really only use 10 percent of their brain. then surely telepathy or telekinesis would be no problem if people could finally access 100 percent of their brain power. like lucy and the film of the same name. while the rest of us bumble along out of people in 10 percent.

that's a myth that is more hollywood the reality. using only 10 percent of the organ that consumes the most energy would be a huge evolutionary disadvantage. even asleep we use far more than a 10th of our brain. no one knows exactly where the persistent 10 percent myth comes from it's been mr tributed to many people including albert einstein and my heart back to a misunderstanding about the very positive by psychologist william james under student boris see this is. serious the sun was a child prodigy. 18 months reportedly could read. newspaper. later it was claimed that he had an i.q. of 254000000 james then said in a lecture. people only meet a fraction of their full mental potential. but he said nothing about 10 percent or

part of the brain remaining on used. pop culture has also helped to perpetuate the myth. of course some areas of the brain may be more active than others but none are completely idle if they can't receive stimuli they'll find another job to do. for example in blind people the visual centers of the brain can adapt to help process order tree signals . brain cells tend to atrophy if their own news. quite apart from conscious decision making the brain has plenty to do filtering impressions regulating breathing controlling reflexes hunger and thirst and much more besides. the fact is only people who suffer real brain damage can no longer use certain parts of their brain. the rest of us can access all of those

billions of brain cells. for decades the moon seemed to be forgotten as a destination for space travel but now in the u.s. space race is on. an outpost on the moon any time soon join us for that next week by. good.
