educational concept the discovery tour could prove very useful for schools and museums. normally we wait we make a game for entertainment for fun and we do discrepancies with history with which we create the narrative we create the story this time around we re used the same environments but it s not about conflict anymore it s not about the narrative it s a little more about taking the time to explore. after a while developers realize that some of the hieroglyphs ancient egyptian writing can be extremely difficult to decode that gave them an idea for a research project which google wanted

them where as when we use a computer and a human we can do it easier. the computer uses artificial intelligence the coffee can help prevent someone from having a heart attack or getting neurological disease or cancer that s going too far. overall what is true is that the study has shown for the first time that affects also verifiable effects could exist. nutrition expert questions ina is a big fan of the beverage both privately and professionally he recommends coffee to patients with diseases of the liver. there s no disputing that caffeine consumption has a strong protective effect when it comes to liver disease not just in terms of helping to reduce inflammation but also in hindering liver fibrosis pathological changes to its connective tissue. for patients who have to actually live a disease not caused by excessive alcohol consumption seen a recommends up to six cups of coffee a day he says one compound in particular plays a key role. for the caffeine in coffee or first specific cell types in the liver by inhibiting their activity. and in the end that helps forestall liver fibrosis and that in turn stops the advance of liver failure or cirrhosis. researches at the university of kaiser is loud turn in western germany have discovered that coffee can even affect your genes. were able to show that the regular consumption of coffee protects d.n.a. and that in turn could be associated with prevention of degenerative diseases like cancer or alzheimer s. in that four weeks study the researchers looked at d.n.a. isolated from the blood of eighty four men half of the test subjects strength three large cups of black coffee a day the other half drank the same amount of water. in the end the team examines d.n.a. samples from both groups. that s just it in africa is the d.n.a. from two cells on the left hand side is the damage d.n.a. is pretty diffuse that s because these fine breaks in the molecules create this halo effect live on the right as a cell with little or no damage to the d.n.a. we were able to show that four weeks of coffee consumption in our test subjects reduced this minor damage. to. the way the coffee is prepared has an impact on this effect espresso beans a roasted longer than those for drip coffee that reduces the amount of acid in the concentrated shot making it easier on the stomach but filtered coffee contains less of the compounds caff a stolen car will two substances that have a negative effect on cholesterol levels in the blood they don t pass through the filter so for those who have high cholesterol levels filter coffee is the better choice. because of it stimulating effect cardiologists used to warn heart patients to stay away from coughing but they ve now changed their minds. and you mentioned some people have heart palpitations after two cups or higher blood pressure those patients should stop with one. but if you like to drink up to five cups a day and tolerate it well then from a medical point of view there is no reason to stop. the. exceptions to that rule are pregnant women or those who show symptoms of bone loss as well as patients with cardiac arrhythmia. the study shows that drinking coffee could have negative effects in such cases there are more than a thousand compounds in coffee research is still trying to figure out exactly which aren t good for you you could just has a little shall we have to look and see whether we can enrich a particular substances in the beans and whether we ll be able to isolate them for possible uses medications that s the direction research is taking over. it s a given thing if this notion of execution. that s entailed then go ahead and treat yourself to a tasty cup of java. whether it s good for us or not one thing coffee does have is a distinct aroma. how does a little smell test is it when you find nice or unpleasant and what about fish or lemons. germans tend to associate the scent of lemons with kenyan this but for spaniards chlorine smells fresh blood russians feel a waft of light that smells clean now tell you from poland wants to know more about what s in those know. why do we experience some smells as pleasant and others much less so. lavender what a wonderful scent. the process of smelling itself is very complex after inhaling the said molecules bind to specific sites on all factory receptors there are three hundred fifty different kinds each is specialized for certain smells. the odor information reaches the long term memory and has strong connections to emotional centers. whether or not we d like a scent mainly depends on the context in which we first smelled it. we first experience many smells when we re very young even while still in the womb or later as an infant. by the way smelling is also important for flavor perceptions ninety percent of them arise not on the tongue but via our factory signals whether or not truffles taste good largely depends on whether we like the aroma. sense awaken memories and can put us in a particular mood that s why the purview ministry is so profitable. apart from that how we re used and social conventions also play a role. takes what for example that smells bad at least that s what we ve been taught that s why some go to great lengths to mask it. the problem is read write obert rather than leave it. to you have a science question that you ve always wanted on

t we need that epidermal ensemble minute might spread sample they live on and in our hair follicles their favorite meal seba but when this monogamy is out of balance you might find yourself with an x. to scratch. it makes sense to take good care of your skin because it s far more complex than it looks the average person has almost five million haris all over their body a miniature forest and habited by a host of tiny organisms. among them bacteria viruses found die of months it s a microscopic zoo and if all its inhabitants are in equilibrium your skin does just fine. but when they aren t you can develop conditions like any topic dermatitis. reuben heritable has had skin. problems all his life at least in part due to imbalances in his micro biota with help from the latest research he hopes his skin will soon be able to heal itself. claims the inflammations i get can hurt quite a lot of. dermatologists painter shmeat glendon maya is convinced that the distribution of microorganisms on the skin plays a central role and that s how. you carry a range of microorganisms some are good for the skin for instance they can protected by renewing its lip at layer but there are also microorganisms that are harmful that can cause infections or as is the case with a topic dermatitis to make them worse usually. so what makes microorganisms trigger a topic dermatitis and research is that a swiss alpine clinic in the town of davos are trying to find out they re carrying out a joint study with environmental medicine specialist claudia title hoffmann from alex brick university in germany. not only to there s a lot going on in the field of a talk that demi titus. the dermatologist takes skin swabs she wants to use the samples to measure what s called the skin microbiome by identifying every species of microbe that lives on the patient s inflamed skin. it s our work currently focuses on the micro biome and we ve discovered that it s not in equilibrium in patients with a topic damage titus and other chronic skin diseases there were microbes called stuff like caucus oreo s predominates and other species a few are further between. the outer surface of the human body is a biosphere in its own right around one hundred billion bacteria viruses fungal and mites live on each and every one of us together with microbes that live and find us they make up the micro biome. a baby s first exposure to microbes occurs during birth when it comes into contact with its mother s flora that s why an individual s microbiome is similar to that of other family members. but similar does not mean identical. microbiomes are unique just like fingerprints. and throughout our lives the microbiome constantly interacts with the environment we pass our microbes along to objects people and animals and receive there is a return to healthy microbiome researchers believe it s stable because it s diverse . cloudier title hoffman is now trying to determine who and how to exact microbial makeup. that s no easy task because there is no way to distinguish between species under a microscope. each bacteria virus or fungus has to be identified genetically through d.n.a. testing. and. it s a laborious process. we all know the gene data looks confusing if you don t know how to read it. you know but ruben hurtles results are clear cut. here then you can see here is that our patient with serious a topic dermatitis has a lot of stuff. on his skin this red bar here that s it in fact that saw compare this to results from a healthy subjects the picture there is much more colorful a mass how it should be health is closely tied to microbial diversity. in an attempt to influence the micro biome the dermatologist applies a special cream to a test area she wants to encourage the growth of microorganisms that will help supplant the overly dominant staphylococcus aureus it s an approach that could spark a revolution and allergy therapy very good anyhow if we can make an improvement here and we ll finally have acquired some tools with which we could help many patients with the haitian. who reuben hagel is hopeful the treatment will work. if it does he might soon have a cream to change his skin micro biome for the better. hopefully the cream will work. but all medications that we run into our skin all swallow eventually end up in our water and ultimately inside of us that al was it could soon be clear and clean in. a romantic little river in southern germany. clarified water from a nearby sewage treatment plant feeds into it it seems clean but looks can be deceiving that water still contains residues from drugs like painkillers antibiotics and blood pressure medication many rivers in germany now contain heightened concentrations of the pain reliever di cliff a knack even though some sources of drinking water but that s not the only reason why water chemists at the regional environment office are concerned about drug residues. in the student being a stickler for not we can prove with our own studies that even at low concentrations of an act has an effect on organisms in the water for trout for instance which causes changes in their gills and in the kidneys and we re also focusing on former for example birth control pills which in extreme cases they can lead to the feminization of organisms so for preventive reasons we don t want these substances and drinking water because. that s why a team of environmental scientist taking part in a pilot project at a very and sewage treatment plant is now trying to filter drug residues out of waste water it s a real challenge because medicines don t break down easily. by made the comment of corn to be effective medications have to fulfill certain criteria they must be stable but resistant. they need to have a long shelf life and reach certain parts of the body where they re needed so they have to remain stable during and sematic reactions. that stability is also the reason why the body doesn t completely absorbed medications so a proportion of the medications you take are eliminated by urine. up to seventy percent of the dye cliff and knock you swallow is excrete again residue from creams and gels is also rinsed away in the shower bath and ends up in the waste water. the bavarian researches have built a reactor that can break down stable drug residues in it wastewater is pulsed with ozone the process is already used to kill. but it also breaks down drug residue into their constituent parts. samples of waste water that have been treated with ozone illustrate how well it works they re carefully analyzed by vanoc rifa noises colleagues at the regional environment office they conduct tests for example in a comparison untreated samples turned reddish orange samples treated with ozone remain clear. but ignore warnings even when it comes to hormones we re very satisfied after ozone nation there are practically undetectible but with other medications the situation isn t quite as rosy we have some good rates of degradation over ninety percent for example with type of a knock on average we re at about eighty five percent but that s not quite good enough since some of these medications like blood pressure drugs are not completely broken down by ozone nation another aspect is that the process of degradation could create problematic transformation products. so otoh no login isn t sufficient that s why in an additional treatment step the bavarian team is also testing two different filter systems the first employs salmon bacteria. the second uses activated carbon granules in early trials it was much more effective that s because the compounds left over after the nation and here are readily to their uneven surface but the system has a drawback after two years that the latest the activated carbon particles are covered completely they can t absorb any more so the filters have to be swapped out and cleaned. just complicated and expensive. that s why the researchers have high hopes for a new activated carbon process that harnesses nature. as the sun is a kind of what s special about this granulated activated carbon is that when this carbon is exhausted completely fall a bio film forms on its surface and the microorganisms in this biofilm degrade the residues biologically in other words this activated carbon has an advantage it can clean itself that of course also brings an economic advantage because we can leave the carbon in the filter for longer and that in turn lowers operating costs significantly. in twenty seventeen global sales of medications it around seven hundred ninety billion dollars that s one hundred fifty billion more than a decade before the race is on to find economical ways to sterilize water and remove drug residues but these researches have to be patient it can take about a year for a biofilm to form an activated carbon only then will they know whether the process could also work in large treatment plants. how often do you say yes when you really mean no. it happens a lot to all of us we all lie every day several times and that has massive consequences for our health but can we change our

plague of online trolling the most popular video game in the world right now and a giant portrait of a football player but first making the world a better place with digital technology developers and. entrepreneurs are creating new apps that can help the poor they can even be used to detect and prevent disease . it s estimated that over eight hundred million people around the world do not have

forum this year steam global inequalities and how best to combat the. digital technology is important for fighting global inequalities because it is perhaps digital and all the technology is with it up perhaps the most important innovation of this time that goes from ups to resources it irrelevant content in relevant languages to different groups this is absolutely fundamental. in nigeria somebody is home and kenya apps have already helped to tackle some local issues a few years ago a telecoms company introduced a digital payment system enabling people without bank accounts to conduct transactions this up and spied other similar projects such as a little cap a taxi service not unlike in berlin us female customers can explicitly request a woman at the wheel which hasn t turned also

the apple so features an online marketplace where farmers can sell their goods directly to avoid expensive intermediaries it s one of many examples of digital technology helping in the fight against inequality. any access to digital technologies will only amplify what exists in that particular society it is not up to digital alone it can be great in the blood of racing and eroding inequalities i could also be a great amplifier of them it all comes down to how we let that technologies work for us and how willing we are to factor in all the challenges and inequalities already exist in society so that we can make sure the digital works for us as opposed to against us. so long as digital technology is freely accessible and used responsibly it can open up opportunities and help to make the world a fair a place. to. shift to improving the world through innovation. and now preprogramed how we re manipulated online without realizing it today trolls . people or programs that post one sided inflammatory content they aim to offend and love to dominate online discourse and they re easily provoked often one comment is enough to draw them out but maybe they shouldn t be taken so seriously don t feed the trolls is what some say and just relax. but if nobody challenges the trolls they ll have achieved their aims giving the impression that most people agree with them some trolls attack minorities others spread conspiracy theories they all disrupt reasonable online debate. so don t just lean back and. nor them the better option is to try and find out who is trolling many professional human trolls are paid to write comments on popular blogs or the websites of major media outlets. then there are programs that post pre-set comments automatically. trolls rarely have friends or personal photos on their personal profiles it makes no sense to try to reason with them since they re probably products of a troll factory instead other users should report them. but what can users who are trolls really do call on others for help. trolls can only be bought together. they might never give up but at least they won t get what they want undivided attention. and now fortnight battle royal is the most popular game in the world gamers don t pay to play but they do have to shell out for upgrades and extra features and the makers are raking in a fortune. the game begins with up to one hundred players skydiving down to an island sounds delicious but then the carnage begins the aim is to be the last player alive. as simple as that over one hundred twenty five million users have registered to play the game so far it s pretty of charge to play but it does cost a lot to acquire certain weapons or accessories that will help a player survival. i bought one day and. so. i spent twenty dollars. forty. six. to developers at epic games seem to have hit a winning number they re making some two hundred fifty million euros a month from the players and my understanding is the game is monetizing roughly a two billion dollars a year run rate and for some perspective that puts it up there with you know these major star wars movie box office will be one and a half to two billion dollars so these are big numbers the fortnight is putting up right now and it s not only the makers who are making a killing from the violent action games professional gamers and streamers are also benefiting one of the most famous is ninja he has millions of followers. is currently the most viewed game on you tube ahead of minecraft. i think they re trying this year is going to be how people go. because it s just such a huge fortnight. and i m around the biggest guy in the world right now so he. like games like call of duty and battlefield not the big shooters you kind of have to show up

acclaimed illustrator stanley child was a huge football fan and a supporter of manchester united he wanted to pay an artistic tribute to his favorite players from around the world. the ball was a big

coffee is it healthy or not. our skin is literally crawling with millions of minute creatures. and our water is laced with traces of medication how can it be removed. these onto your average doodles or scribbles on their hieroglyphs the writing system used in ancient egypt this symbol of vulture corresponds to the less say. this with a sense of the lesser only. other symbols represent whole words like water. or god. not everything has been decided in the ancient texts that have been found to date but it is getting easier to do with the help of unsufficient intelligence. hieroglyphs pyramids and pharaohs are all part of the assassin s creed origins video game developers added an educational feature based on authentic ancient egyptian sources canadian historian maxine dong helped develop the educational concept the discovery tour could prove very useful for schools and museums. normally we wait we make a game for entertainment for fun and we do discrepancies with history we recreate the narrative we create the story this time around we re used to same environments but it s not about conflict anymore it s not about the narrative it s really more about taking the time to explore. after a while developers realize that some of the hieroglyphs ancient egyptian writing can be extremely difficult to decode that gave them an idea for a research project which google wanted to support. realize that there s a. potential to decipher the year and with it to make it more accessible it takes years and years for someone to learn how you re just with ovitz and where as when we use a computer and a human we can do it easier. the computer uses artificial intelligence the computerized program learns to recognize and translate hieroglyphs the hieroglyph project needs a vast quantities of data so egyptologists worldwide are using an open source software to upload and share images of ancient inscriptions to the platform. so the first book in the project will be extracting the card with a promise from a wide variety of original sources before working on the tools and algorithms that come to recognize in the darkness ultimately then we can analyze existing translations matching card sequences to unlock them meaning. that could be a boon for tony or sebastian rishta a professor of egypt on a g. at the free university in berlin. his team has been working on an electronic dictionary of an ancient egyptian for some thirty years it s still unfinished as hieroglyphs are far more complex than letters in a modern alphabet. and dozens of which is that unlike our abstract letters hieroglyphs or pictorial so you could draw them like tiny logos and make very. action. you could place this or that into the hands of these little figures and that leads to the essential problem here the symbols are ambivalent even if. there are several variations of the same symbol. this is. the study of egyptology lacks enough funding to regularly work with artificial intelligence wish to welcome the game developers initiative but a usable computer translation from hieroglyphs is still a long way off. its machine just as you could hardly translate korean texan into german with today s computers if you can imagine how difficult it would be in to achieve a grammatically and linguistically correct translation from a string of hieroglyphics symbols into any modern language. scientists and gamers are working together to solve the riddle survey ancient egypt the databases are growing fast as egyptologists contribute decrypted translations to the new digital hieroglyph library. the way the ancient egyptians wrote their hieroglyphs in rows columns that can be read from left to rice bowl from right to left an advantage for both right and left handed scribes

coffee but she hated the pesky grounds that stuck to her tongue. then she had no idea she punched holes in a pot with a nail put in a piece of blotting paper on the coffee filter was invented. after applying for a patient she started a filter producing company. a simple process first the filter then ground coffee beans and hot water and outcomes delicious coffee free from those insufferable grounds. coffee has often been the subject of scientific studies a recent one caused euphoric headlines the authors say the beverage is a real panacea according to the analysis regular consumption supposedly lowers the risk of heart attack stroke and even cancer. although there isn t solid proof yet the study says indicators on strong. showings of long can be said is that car for years and harmful and that it really does minimize risks associated with cardiovascular disease stroke and heart attacks. so for me personally saying that coffee can help prevent someone from having a heart attack or getting no logical disease or cancer that s going too far. overall what is true is that the study has shown for the first time that affects also verifiable effects could exist. nutrition

tiny organisms. among them bacteria viruses found guy at mines it s a microscopic zoo. and if all its inhabitants are in equilibrium your skin does just fine. but when they aren t you can develop conditions like any topic dermatitis. reuben heritable has had skin problems all his life at least in part due to imbalances in his micro biota with help from the latest research he hopes his skin will soon be able to heal its. self. claims the inflammations i get can hurt quite a lot. dermatologist painter she is convinced that the distribution of microorganisms on the skin plays a central role and that s how. you carry a range of microorganisms some are good for the skin for instance they can protected by renewing its lip at layer but there are also microorganisms that are harmful that can cause infections or as is the case with a topic dermatitis to make them worse. so what makes microorganisms trigger a topic dermatitis and research is that a swiss alpine clinic in the town of davos are trying to find out they re carrying out a joint study with environmental medicine specialist cloudier title health money from alex morgan of versity in germany. there s a lot going on in the field of a topic dermatitis. the dermatologist take skin swamps she wants to use the samples to measure what s called the skin micro biome by identifying every species of microbe that lives on the patient s inflamed skin with. our work currently focuses on the micro biome we ve discovered that it s not in equilibrium in patients with a topic demonstrators and other chronic skin diseases there were microbes called stuff like caucus oreo s predominates and other species a few are in further between. the outer surface of the human body is a biosphere in its own right around one hundred billion bacteria viruses fungal and mites live on each and every one of us together with microbes that live and find us they make up the micro biome. a baby s first exposure to microbes occurs during birth when it comes into contact with his mother s flora that s why in individuals microbiome. it s similar to that of other family members. but similar does not mean identical. micro biome is are unique just like fingerprints. and throughout our lives the microbiome constantly interacts with the environment we pass our microbes along to people and animals and receive players in return for healthy microbiome researchers believe it s because it s diverse. cloudier title hoffman is now trying to determine who can hurtles exact microbial makeup. that s no easy task because there is no way to distinguish between species under a microscope. each bacteria virus or fungus passed to be identified genetically through d.n.a. testing. it s a laborious process. we all know the gene data looks confusing if you don t know how to read it. but reuben heard results are clear cut. here then what you can see here is that our patient with serious a topic dermatitis has a lot of stuff. on his skin this red bar here that s it in fact that saw compare this to results from a healthy subject the picture there is much more colorful and that s how it should be health is closely tied to microbial diversity. in an attempt to influence the micro biome the dermatologist applies the special cream to a test area she wants to encourage the growth of microorganisms that will help supplant the overly dominant staphylococcus aureus it s an approach that could spark a revolution and allergy therapy very good anyhow if we can make an improvement here and we ll finally have acquired some tools with which we could help many patients with the haitian. reuben harrell is hopeful the treatment will work. if it does he might soon have a cream to change his skin microbiome for the better. hopefully the cream will work. but all medications that we run into our skin all swallow eventually end up in our head and ultimately inside of us that al water could soon be clear and clean in. a romantic little river in southern germany. clarified water from a nearby sewage treatment plant feeds into it it seems clean but looks can be deceiving that water still contains residues from drugs like painkillers antibiotics and blood pressure medication many rivers in germany now contain heightened concentrations of the pain reliever die cliff and knock even though some sources of drinking water but that s not the only reason why water chemists at the regional environment office are concerned about drug residues. in the student being a stickler for not we can prove with our own studies that even at low concentrations of an ak has an effect on organisms in the water trout for instance which causes changes in their gills and in the kidneys and we re also focusing on former for example birth control pills which in extreme cases they can lead to the feminization of organisms so for preventive reasons we don t want these substances and drinking water because. that s why a team of environmental scientist taking part in a pilot project at a big varian sewage treatment plant is now trying to filter drug residues out of waste water it s a real challenge because medicines don t break down easily. by made the comment of corn is and to be effective medications have to fulfill certain criteria they must be stable but resistant. they need to have a long shelf life and reach certain parts of the body where they re needed so they have to remain stable during and sematic reactions. that stability is also the reason why the body doesn t completely absorbed medications so a proportion of the medications you take are eliminated by urine. up to seventy percent of the dye cliff and that he swallowed is excrete again residue from creams and gels is also rinsed away in the shower bath and ends up in the waste water. the bavarian researches have built a reactor that can break down stable drug residues in it wastewater is post with ozone the process is already used to kill. but it also breaks down drug residues into their constituent parts. the samples of waste water that have been treated with ozone illustrate how well it works they re carefully analyzed by vanno rifa noises colleagues at the regional environment office they conduct tests for example in a comparison untreated samples turned reddish orange samples treated with ozone remain clear. but in overall exhibit when it comes to hormones we re very satisfied after ozone nation there are practically undetectable but with other medications the situation isn t quite as rosy we have some good rates of degradation over ninety percent for example with type of a knock on average we re at about eighty five percent but that s not quite good enough since some of these medications like blood pressure drugs are not completely broken down by ozone nation another aspect is that the process of degradation could create problematic transformation products. so those own alone isn t sufficient that s why in an additional treatment step the bavarian team is also testing two different filters says. thems the first employed salmon bacteria. the second uses activated carbon granules in early trials it was much more effective that s because the compounds left over after the nation and here readily to their uneven surface but the system has a drawback after two years at the latest the activated carbon particles are covered completely they can t absorb any more so the filters have to be swapped out and cleaned which is complicated and expensive. that s why the researchers have high hopes for a new activated carbon process that harnesses nature. and what s special about this granulated activated carbon is that when this carbon is exhausted completely fall of biofilm forms on its surface and the microorganisms in this biofilm degrade the residues biologically so in other words this activated carbon has an advantage it can clean itself that of course also brings an economic advantage because we can leave the carbon in the filter for longer and that in turn lowers operating costs significantly. in twenty seventeen global sales of medications it around seven hundred ninety billion dollars that s one hundred fifty billion more than a decade before the race is on to find economical ways to sterilize water and remove drug residues but these researches have to be patient it can take about a year for a biofilm to form an activated carbon only then will they know whether the process could also work in large treatment plants. how often do you say yes when you really mean no. it happens a

will present the letter only. the other symbols represent whole words like water. or god. not everything has been decided in the ancient texts that have been found to date is getting easier to do with the help of artificial intelligence. lives pyramids and pharaohs are all part of the assassin s creed origins video game developers added an educational feature based on authentic ancient egyptian sources. canadian historian maxine deal on helped develop the educational concept the discovery tour could prove very useful for schools and museums. normally we wait we make a game for entertainment for fun and we do discrepancies with history we recreate the narrative we create the story this time around we re used the same environment but it s not about a conflict anymore it s not about the narrative it s really more about taking the time to explore. after a while developers realize that some of the hieroglyphs ancient egyptian writing can be extremely difficult to decode that gave them an idea for a research project which google wanted to support. realize that there s a technique potential to decipher billiard with it to make it more accessible it takes years and years for someone to learn how your glyphs that we re with over them where as when we use a computer and the human we can do it easier on. the computer uses artificial intelligence the computerized program learns to recognize and translate hieroglyphs the hieroglyph project needs a vast quantities of data so egyptologists worldwide are using an open source software to upload and share images of ancient inscriptions to the platform. so the first looking across it will be extracting a card with a promise from a wide variety of original sources before working on the tools and algorithms that come to recognize in the darkness automatically then we can analyze existing translations matching hard sequences to unlock them meaning. that could be a boon for tonio sebastian rishta a professor of egypt ology at the free university in berlin. his team has been working on an electronic dictionary of an ancient egyptian for some thirty years it s still unfinished as hieroglyphs are far more complex than letters in a man. an alphabet. unlike our abstract letters or pictorial so you could draw them like tiny logos and make variations. you could place this or that into the hands of these little figures and that leads to the essential problem where the symbols are ambivalent even just. there are several variations of the same symbol. as. the study of egyptology lacks enough funding to regularly work with artificial intelligence welcome the game developers initiative but a usable computer translation from hieroglyphs is still a long way off. with. the text. just as you could hardly translate korean text into german with today s computers. you can imagine how difficult it would be in to achieve a grammatically and linguistically correct translation from a string of hieroglyphics symbols into any modern language. scientists and gamers are working together to solve the riddles of ancient egypt the databases are growing fast as egyptologists contribute decrypted translations to the new digital hieroglyph library. the way the ancient egyptians wrote their hire adrift in rows columns that can be read from left to rice bowl for the right to left and advantage for both right and

most people only realize their preference once thank you lloyd with someone else go ahead give it a try. brewing coffee was once quite a messy affair milly s have been found that annoying she was a housewife who lived in dresden at the end of the nineteenth century and she loves coffee but she hated the pesky grounds that stuck to her tongue. then she had no idea she punched holes in a pot with a nail put in a piece of plotting paper on the coffee filter was invented. after applying for a page and she started a filter producing company. a simple process first the filter then ground coffee beans and hot water and outcomes delicious coffee free from those insufferable grounds. coffee has often been the subject of scientific studies a recent one caused you far a cad lines the authors say the beverage isn t real panacea according to the analysis regular consumption supposedly lowers the risk of heart attack stroke and even cancer. although there isn t solid proof yet the study says indicators on strong. can be said is that car for years and harmful and that it really does minimize risks associated with cardiovascular disease stroke and heart attacks. so for me personally saying that coffee can help prevent someone from having a heart attack or getting no logical disease or cancer that s going too far. overall what is true is that the study has shown for the first time that affects also verifiable effects could exist. nutrition expert questions ina is a big fan of the beverage both privately and professionally he recommends coffee to patients with diseases of the liver. there s no disputing that coffee consumption has a strong protective effect when it comes to liver disease not just in terms of helping to reduce inflammation but also in hindering liver fibrosis pathological changes to its connective tissue. for patients who have to actually live a disease not caused by excessive alcohol consumption you know recommends up to six cups of coffee a day he says one compound in particular plays a key role. in uncover the caffeine in coffee or first specific cell types in the liver by inhibiting their activity. and in the end that helps forestall liver fibrosis and that in turn stops the advance of liver failure or cirrhosis. researches at the university of kaiser is low and they and that in turn could be associated with prevention of degenerative diseases like cancer or alzheimer s. in that week s study that researches looked at d.n.a. isolated from the blood of eighty four men half of the test subjects strike three large cups of black coffee a day the other half drank the same amount of water. in the end the team examined d.n.a. samples from both groups. this is the d.n.a. from two cells on the left hand side is the damage d.n.a. is pretty diffuse that s because these fine brake. when the molecules create this halo effect live on the right is a cell with little or no damage to the d.n.a. we were able to show that four weeks of coffee consumption in our test subjects reduced this minor damage. to. the way the coffee is prepared has an impact on this effect espresso beans a roasted longer than those for drip coffee that reduces the amount of acid in the concentrated shot making it easier on the stomach but filtered coffee contains less of the compounds caffe a stolen car will two substances that have a negative effect on cholesterol levels in the blood they don t pass through the filter so for those who have high cholesterol levels filter coffee is the better choice. because of it stimulating effect cardiologists used to warn heart patients to stay away from coughing but they ve now changed their minds. and you mentioned some people have heart palpitations after two carbs or higher blood pressure those patients should stop with one. but if you like to drink up to five cups a day and tolerate it well then from a medical point of view there is no reason to stop. exceptions to that rule are pregnant women all those who show symptoms of bone loss as well as patients with cardiac arrhythmia. the study shows that drinking coffee could have negative affects in such cases there are more than a thousand compounds in coffee research is still trying to figure out exactly which aren t good for you you get used to exactly so shall we have to look and see whether we can enrich particular substances and the beans and whether we ll be able to isolate them for possible uses medications that s the direction research is taking. it is essential to a future. that s entailed then go ahead and treat yourself to a tasty cup of java. whether it s good for us or not but one thing coffee does have is a distinct aroma. how about a little smell test is it when you find nice or unpleasant and what about fish or lemons. germans tend to associate a sense of lemons with kenyan this but for spaniards chlorine smells fresh blood russians feeling left of like that smells clean that s from poland wants to know more about what the no snow. why do we experience some smells as pleasant and others much less so. lavender what a wonderful scent. the process of smelling itself is very complex after inhaling the said molecules bind to specific sites on our factory receptors there are three hundred fifty different kinds each is specialized for certain smells. the odor information reaches the long term memory and has strong connections to emotional centers. whether or not we d like a scent mainly depends on the context in which we first smelled it. we first experience many smells when we re very young even while still in the womb or later as an infant. by the way smelling is also important for flavor perceptions ninety percent of them arise not on the tongue but by all factory signals whether or not truffles taste good largely depends on whether we like the aroma. sense awaken memory and can put us in a particular mood that s why the purview ministry is so profitable apart from that how we were raised and social conventions also play a role. takes what for example it smells bad at least that s what we ve been taught that s why some go to great lengths to mask it. because it is right right. even if they. do have a science question that you ve always wanted answered it we re happy to help out and send it to us as a video text ovoid smell we all saw it on the show will send

for cruise ships how does that work. in kenya the outlook is bleak for many young people but now some comic book heroes are coming to the rescue. and new technologies are making us question one of our most important senses can we still trust our lives. we all have pictures in our heads and they can be extremely powerful we process images sixty thousand times more quickly than we do written words they arouse our emotions they can move us make us laugh feel happy or sad. but images can also be deceptive and they can be manipulated now even moving images can be altered making it possible to create extremely authentic looking fake news videos. have decided to resign from the of the president decided to resign from the bears of the press. is the next generation off a commute on the left trunk space but his facial expression and words are actually being generated by an actor. animation software developers like haile are busy perfecting the technology behind such high resolution facial mapping. customized. fourteen thousand to create these hyper realistic images. you can see cookies screwed up face that we just photograph and you can see here it s all rendered in three d. and what s really effective about this device is that it even shows the pores we can zoom in here and see all the lines on his face. so i can. team of developers aren t interested in creating fake. they re focused on creating new communication tools. possible for anyone to create three dimensional avatars for use in various applications for instance in the film industry. could generate a new video with my features mapped onto someone else s and of course i could also morph my face on today is so i would actually look like them and have human under the specialized software creates a template which captures facial expressions in three d. this mosque in the me manipulation is needed it s even possible to use regular photo however there s no way to control how people. look. at hasn t been abused much to create fake news but i have no doubt that that will happen there s already a lot of software that people are uploading to the internet which people can use to map the face of one person on to someone else s. so the possibility already exists to generate videos of people doing things that haven t happened in reality. the. scientists in germany are also. scrutinizing the faces a group of researchers from the commonwealth institute for integration circuits are teaching computers to read human emotions what technology advances open up possibilities they also give rise to unintended developments. of course of first and foremost you have to ask how these technologies are going to be applied. you have to set clear boundaries and establish press what is permissible ethically and legally. so yes we give a lot of consideration to the ethical legal and social impact of our research. picked from. hoover got us and his team are working with program similar to those in california they hope to develop intelligent systems which can detect for example when nursing home residents who can t speak are in pain but other researchers demonstrate how this technology can be used for less benign purposes. by lift thinking and super imposing their own facial expressions in real time they re able to turn famous politicians into their puppets with additional voice mimicking software you could make it seem as if not a mere fouth you know it donald trump were declaring world war three since people tend to trust videos that could lead to horrific consequences if we conducted them at will it will be hard to tell what s real and what s not. but it s important for us to research the subjects in particular here in germany and europe so we can better understand how these technologies work. this will allow us to predict what might be possible in the future. if we don t it ll be left in the hands of major corporations like google and facebook. the potential dangers are already being acted upon developers are devising software to detect whether videos are fake or not. if videos go viral in the internet you have to be very careful the most important thing is that people understand what s possible now. for better or worse experts say that these technologies will be a part of everyday life over the next decade in the near future we won t be able to say that seeing is believing. this difficult to be president manipulated video spread like wildfire on social media networks authenticity is the currency of our time so trust us and follow us on. society. many children under eighteen lose one or more parents due to war disease or natural disasters according to unicef in two thousand and fifteen there were almost one hundred forty million orphans worldwide . countless iraqi children witnessed horrific events during the bitter fighting and siege of the city of mosul many have been left physically and emotionally traumatized they ve lost their parents and are now completely dependent on aid. mornings or the highlight of sakina mahomet s day the children greet her with huge hugs they re playful and happy now but they share a sad past these children were orphaned during the islamic state militant groups reign of terror iraqi special forces recovered them from the rubble in mosul. this orphanage is now their home here they re safe and can express their hopes. and then i want to work at a company. school principal this is the i want to study at university. i s wouldn t allow it to cation for girls i don t have in the us but it s ok to mohamed wants to give these children a chance to flourish but the head of the orphanage says money and resources are a constant issue key to the an issue i m so sad that i can t really help them. i go to the government again and again and ask them for books and help has probably been that i beg them to make improvements and decisions. but nothing happens this leaves children like adam in the lurch the toddler was conceived when his father and i as militant raped his mother a u.c.d. women from the kurdish religious minority were systematically subjected to kidnapping and sexual assault under i.i.s. autumn s mother has since returned to her husband and their three children leaving him here you know what was he his mother is eighty her religion forbids had to raise the children of muslims. yet. that s why she gave his son to the old financial model in japan and saved his life in. the militants tore apart families in mosul shiite muslim children like ramiro and ali were taken from their parents and given to supporters after the city was freed their uncle found them here at the orphanage now he wants to raise them. but years of brainwashing have left their mark. and that s what. they were taught when our u.s. believes. now only hates iraqi police and soldiers. he sings songs its ideology has shaped his thoughts. the idea of. islamic state didn t just leave behind destruction in mosul they sowed hatred in people s hearts. pious snipers even used children as bait when iraqi soldiers came to rescue the children they were ambushed. was used this way he was dragged out of a firefight by a dog as iraqi special forces closed in the baby survived but lost his arm he s just eight months old and no one knows what s happened to his parents and he doesn t know what has me most children can hold milk bottles at eight months but he can t because he s missing an arm and he s often ill and needs a lot of care you haven t got a huge amount of the key right here there are many such sad stories here at the orphanage but at least now the children can laugh sing and dream of a better future. many children and young adults around the world share that hope of a better future in sub-saharan africa more than sixty percent of the population is under twenty five many of them long to have fulfilling work yet more often than not that dream remains a dream. kenya has particularly high levels of youth unemployment around twenty percent says the world bank many young people move from rural areas to the cities where they end up living in slums. kibera is the largest slum in kenya

younger generation that felt manipulated by politicians and overlooked by the mainstream media burnette wanted to help young people improve their prospects it was a very serious study on a big scale done by a leading academic institution in the us it was a very robust study and it said that young women aged nineteen or less who follow she chose. or so three times less likely to be married at the

and deliver it bigger faster better quicker cheaper on the internet that s that s that s what we re working on more and more people are getting online in kibera too but for the moment the old fashioned comic book continues to inspire people to share their stories and embrace new ideas. and today in global ideas we visit a small island off the coast of mexico. every year cruise ships take millions of passengers to cozumel. but what does that mean for liverpool and wildlife. our reporter chris general man trap will to cozumel to find out more about how people that are protecting their island paradise. but i mean this island is my home and i m grateful that i get to meet so many people here tourists ships cruise people from around the world. well it s a great place to work as a biology professor he has. so many nature so many species and they have to be protected. by discard the save beauty area and the amazing wore off as being a i decided to believe that s my young. men but yes for me cause i m male is a thousand years of history and a world heritage when you get. kozel male lies on mexico s east coast the caribbean island is a favorite tourist destination five million visitors come here every year the harbor is large enough to handle seven cruise ships at any given time when it ships passengers disembark it s like an invasion. posing yetto is in charge of harbor security he s been on the island for twenty years and witnessed how the harbor has been expanded to accommodate the giant cruise liners. the more not tourism is essential for the whole island it s a source of income for everyone working and here. we depend on the tourists mark important to go get an up or down if that you know. but the tourist hordes rarely head into the rain forest canopy covering the island s interior half of which is a protected nature reserve. for. biologist christopher gonzalez wants to see the integrity of the rain forest maintained but these concerns the island. is that a crossroads. i think. they were used to be several years ago. but by now all of the through these that there were. everything. there we ll go from what we have to do now is. that the reality. they re protected areas hard part of the. he d like to see more visitors enjoying the natural wonders here for instance on trekking tours as long as they follow strict guidelines however most tourists usually want to see the islands main attraction it s unique coral reefs but just how long they ll remain intact is a concern. because the med is home to the world s second largest coral reef more than five hundred species of fish live here some threatened by extinction it s a fragile paradise and a valuable treasure. according to a study by the german corporation for international cooperation the deterioration of cozumel coral reefs could cost the island around seventy million euros in income annually. if we lose water quality it will stay clear of the water and we look specious twelve percent of the person that gets the mail won t come back so we are working hardly in order to make the people more conscious about that and when when when i see people talking about tourist but also the guy that goes with the tories they are like our ambassador what they. show what is correct the tories will do. diving instructors right mando ramires is well aware of the relationship the conservation authorities know he s sticking to the rumors because he has to renew his tour card license every two years. well she. is one of the most popular places in cozumel because she is so water to recall use beautiful only one. metre the is full of starfish and usually that people are right to this place take the starfish out of the water take their sails and put it back maybe the other starfish is going to be there the next day that is the lack of education you cannot coach anything. this ignorance is upsetting to her i moaned that s why he only takes small groups down at a time and gives them strict instructions if you don t control your buoyancy while diving and you get close to battery if you re going to hit the reef maybe with your hands but maybe it would get back i mean if you hit the formation or at this point your something with your tank is going to be a big damage. they ll break off and die. most tourists from the ships spend only half a day on the island it s not much time to experience the culture. was a center of mayan religious culture the mayor herself is of mayan discerned which she wishes the tourists would take more interest in the islands culture and history . two to cause amounts of unique geographical location and that we ll never be able to avoid all these cruise ships is a moment though they could. but we shouldn t be afraid to set down rules for the tourists up or let us than that. sit talk and i mean if you re going to destroy the environment then you come to console where they don t patronize our restaurants and shops then you can t come and if you don t enrich our society then you re not welcome here. that most probably again the noise has been the needle. in the evenings when the harbor empties becomes tranquil but only for a few hours the next cruise ships will soon be dark in here again. we love tasting food from around the world today s global snack comes from northern greece. it s a view that s been enjoyed by many including
