When the term. Us our 1st story is all about food tacos are passed out as popular in mexico made with hope marinated in pineapple and cheese. In ivory coast deep fried plantain zora favorite. They may not be low fast but they are super tasty. In india thought out us are a popular staple whether hes in plain all stuffed flavors of an overreliance hes but how does our sense of taste work. Are these cookies tasty. When you like what you see you dig in after all looks count right when chewing you feel the cookie on your tongue is it harder song. Often warm or cold taste begins on the tongue its covered with water culpability they in turn are covered by taste buds. The bumps of the pill enlarge the tongue surface area significantly flavor is analyzed directly at the pill way by the taste buds on its surface. They absorb the substances found in the cookie and direct them to the taste buds sensory cells. These sensory cells are renewed every week. Were able to recognize sweet salty sour and bitter flavors as well as whats called mommy a savory taste associated with meat or cheese. Those 5 basic tastes can be sensed by every area of the tongue which collects information about what is being sensed and relates it directly to the brain. We took to facebook to ask what tastes best to you. Mark a researcher likes to money is a dish made of corn dough wrapped in banana leaves its a speciality from guatemala and mexico. Dominick likes banks and best a condo served with grilled fish. Maybe its a reason loves believe in homey test corn husks filled with seasons cool mix. Kenneth loves kenyan roast goats and corn meal. And does he likes american native chicken dish thats popular in the philippines it looks great. But did you know when it comes to taste all your senses play a part of your sense of smell. Sights touch hearing as well as taste for many of us food is about enjoyment but for one scientist in britain it involves a whole lot more. Eating is a science at least as far as Charles Spencer is concerned the Oxford University professor enjoys manipulating the sense of taste simply by changing the color of the cup music playing in the background you can change the taste of food that is something no one kind of believes. Can possibly be true and theres the job of the gastro physicist to do the experiments to demonstrate the stuff builds an understanding of how the brain works and how the senses can act. According to spence for example the physical shape of a cup alters the taste of the coffee. As you feel something round in the hand that brings out sweet notes as you make the cut more angular that tends to accentuate the acidic notes instead and then by changing color shape of the cup over the surface of the liquid then you can accentuate to enhance the fruiting out. Seeing hearing tasting smelling and touching the full experience of a meal is made up of all the senses and what they come together to create. The self described gastro physicist has played with the concept under the chief results the 1st glance would seem part to prove. Sound as the forgotten flavor sense and that can be the sound of rhythm the sound of the food itself but the crunchy crispy crackling through the sounds of the places in which we eat the sounds of preparation the sounds of the coffee machine we heard over. The sound of music and noise to. Spend says his work has shown that listening to high pitch music while eating makes to taste sweeter. Whereas lower notes trigger associations with a more bitter. Taste experience. So an immediate taste sensation can be enhanced or tempered. Spences Experimental Research even inspired an acclaimed chef to serve diners a plate of seafood with a side of seaside sounds. Under diners reported that the dishes tasted much more authentic. Go would say further on i dont select or create music that has to keep the properties for a high end picture picture rough. With different instruments and by so doing systematically season your food or a whole sonic seasoning. To show that your perception of taste involves all of your senses spence conducted a live survey involving several 100 test subjects. It was a whisky tasting session with different audiovisual backdrops. Participants all sampled the same whisky in a room with grassy turf on the floor while listening to a soundscape recorded in a summer meadow. They then sipped from the same glass in a room containing round forms illuminated in red tones to the sound of high pitch music. The last room how to wooden floor accompanied by the sound of creaking timbers and low notes on wooden instruments each time the participants noted the ratings of the whisky smell taste and texture the results of the 3 hots and 500. 00 people that people said that the glass in us on the nose of the whiskey was about 50 percent higher in the grass root the sweetness was about 10 percent more pronounced in the sweet room and so the texture of the aftertaste in our field of whiskey was about 15 percent higher again in the remote the end and the people who are scorecards could see i know this was he has not left my hand and i can see my scorecard and see that i said defray Different Things about one of the same drink. The results helped to explain a phenomenon that many people are familiar with. That when you go on holiday to the mediterranean as an all the european in the maybe a rose a wine taste wonderful you sitting there by the by the by the shore the sun was beating down you with your family relaxed your whole day one taste wonderful so good youre tempted to buy some and bring it back home and share it with your friends and family on a cold winters night and then you open it they just never quite taste the same. Theres no question that spence enjoys playing around with a sense of taste. As a scientist hes also excited about the opportunities offered by the digital age. If you look at food you can deliver augmenting reality so i can change what this biscuit looks like i can make it bigger or smaller i can change the color or have got Something Like a cup of coffee say im with this as a my colleagues in japan now have it such that i can add cream or i can add make the street look hot up by adding steam flowing off the top the idea is we can make things taste better different make it look like im eating a really big cookie will i be happy with less. My brain figure out that im being fooled how and where you eat and drink the utensils you use. All of that influences your perceptions. So taste to a large extent at least is all in your head. Ahead is one thing this robot doesnt have but hand it is easy to program and can do all kinds of jobs which makes him very popular with scientists some of them announce teaching him and age old school. Ones to the left once to the right hand of the robot is learning to knit his classroom as a laboratory at the Technical University of berlin when his minder. What services panda could learn to perform for Research Purposes they thought why not knitting. Us 1st well find the idea and using it for the more i thought about it the more i thought why we laughing about it. Maybe because we tend to associate robots with a high tech future and not a traditional handicraft another reason for the disconnect many robots today are being designed in ways that propagate gender cliches depending on whether theyre intended for roles considered typically masculine or typically feminine. Behind and we have a very clearly defined division of labor along gender lines and the new technology is simply being slotted into existing social patents. The scientists are hoping to break some of those cliched gender roles with a powerful robotic arm that does nothing. In teaching the robot how to get the researchers have to put themselves in the robots position to understand whats needed. Its a principle that will be even more necessary in the future if robots are to help around the home care for the elderly or the sick. The scientists arent teaching the robot to knit so that it can produce sweaters and socks what theyre trying to do is explore the interaction between people and machines but im only cook when we constantly focus on the cooperation between us as human beings on the robotic arm the goal is not to replace knitting machines or people but to find out whats going on at this interface. And not just via theoretical discussions but also with practical experiments the team is made up of sociologists i. T. Specialists and Socio Cultural analysts the insights gained while teaching panda the robot 10 minute are recorded in an online blog. Knitting classes for robots an unusual Research Project making its own in conspicuous contribution to a future where robots and people will increasingly work side by side and hand in hand. Research out in space would be impossible without the use of robots carrying out tests way humans have yet to trade. Sedation satellites. Space telescopes. And unmanned probes explore everything from planets to the moon to asteroids. Now a new mission scheduled to start next year will focus on the star at the same to. The sun is a see the mass of much air in fractions of a 2nd it produces a 1000 times more energy than the entire human race uses in a year in comparison to the sun earth is minuscule. The star at the center of our solar system blasts mass clouds of electrically charged particles into space some of which can damage satellites. Maybe even knocked out power grids on earth that happened in march 1909 for example. The entire power grid in the canadian province of quebec collapsed after the transformers literally burned through it was the middle of the canadian winter and suddenly 6000000 people were without power. To help protect Vital Technology on earth physicists in the german city of pottstown a study in the sun very closely they want to predict solar storms a number of satellites already providing detailed information about the star and the stormy cloud of superheated gas that surrounds it. Images like this are of course very impressive that Something Special about solar physics compared to astrophysics or extragalactic physics we can actually see the processes happening on the sun they occur in a time scale that we can still observe for ourselves. With help from the European Space agencys solar orbiter satellite the researches want to discover more about how solar storms develop to do so the satellite will need to get extremely close to the sun and then spend 10 days observing just one area of the burning ball of gas the scientists in part stan helps develop an important instrument for the satellite it was tested here at the einstein tower an observatory where Solar Research has been conducted for over 90 years. Now theyre testing complex high tech components for a special purpose telescope. It will be placed on board the solar orbiter for the mission to the sun protected from the intense radiation by a heat shield the telescope will focus on the hottest parts of its atmosphere the regions where solar storms can develop. Every day the scientists here observed the titanic solar forces at work does that change their view of the world. Makes you humble when you realize how unimportant we really are compared to the entire universe we humans often think were so important but were just a tiny speck in the universe subject to the laws of nature. The new satellite is due to launch in 2020 the Scientists Say the data it sends back will give us whole new insights into the way our sun works. The sun is around 150000000 kilometers from earth sometimes its a little closer than that at other times a little further away depending on the earths current position in orbit. Measuring distances in space is something of a science in itself a view in mexico but a question about that. How can distances be measured in outer space. There are cosmic home in the solar system we can still apply common measuring standards such as miles and kilometers. In recent decades weve explored in our own backyard with space probes. And weve even sent human beings to our nearest neighbor the moon which is about 400000 kilometers away. Thats close by compared with the distance of saturn which is about one and a half 1000000000 kilometers away. And wed have to travel over 40 trillion kilometers to get to the next star system. But is that a distance anyone can imagine. Might needs over 4 years to travel that far because light always moves at the same constant speed throughout the universe astronomers can use it to define distances. They can determine how far away a star is using this. Method it involves measuring a given position in the night sky. 6 months later they measure it again they can then calculate the stars distance to us using trigonometry but this method only works for objects relatively close to us up to a distance of about 150 light years if astronomers want to find out the dimensions of the milky way or the distance to our neighboring galaxies they have to use another measuring stick see for your variables see. That at certain periods have a known luminosity. A standard. Astronomers can calculate the distance using the amount of light that reaches their telescope at specific times during a superior pulsation. Specific kinds of exploding stars or supernovae are even brighter standard candles these Light Sources can be detected by the whole space telescope right up to the edge of the visible universe one image shows galaxies that are more than 13000000000 light years away. The deepest view yet into outer space. If our love is right why am i only gave it. To you have a science question that youve always wanted answer it were happy to help out send it to us as a video text over a smell if we answer it on the show well send you a little surprise as a thank you can i just ask. Interested in more stories from the world of science go to our website or find us on twitter or facebook. A number of fish do it. Do some corals and sponges they close in that dark its known as bio fluorescents they have ultraviolet light and projected as a different color and its not just restricted to marine life the phenomenon also crops up on learned sometimes to the surprise of scientists. It all began with a coincidence biologist dubbed the parts or saw a photograph online that showed a chameleon with strange glow in the dark spots. d the chameleon expert was surprised hed never seen the phenomenon in the animals before thats why it 1st put some thought it was a fake then he saw it with his own eyes. His parents are a chameleon also has been exposed to u. V. Light a mysterious fluorescent pattern appears around its skull. Its not like you jump up and yell eureka instead you realize you have all kinds of work still ahead when we stumbled on this we were fascinated that no one had heard of it its an absolutely new phenomenon that had never been seen before and it could be linked to communication just. Cant. Chameleons dont have voices and make very little noise at all. Usually theyre brown and green so theyre already well camouflaged on soil or in vegetation most dont actively blend into the environment. They mostly change color when they want to communicate with each other. Even this coming just shows that comedians are pretty social animals they drop their camouflage when they want to Say Something to another chameleon where the 2 expressed that this is their territory or with my also that they might be interested in mating females on the other hand also have colors that signal to myself that its not worth trying because theyre already pregnant. That shows how important interesting issues communication is also among lizards. So could it be that the mysterious fluorescent patterns are far more ways to communicate. The chance discovery made the researcher curious if the fluorescent patterns were indeed a useful trait in evolutionary terms than other species of chameleon would likely have them too they probably wouldnt be found only in panther chameleons. The researcher hopes to test his theory at munichs bavarian state collection of. One of the largest collections of chameleons in the world is stored here preserved in alcohol. Generally its pretty much impossible to draw any conclusions about body color when i specimen is preserved in alcohol chameleons fade quite quickly and the original color of bleach is out. Its not yet clear whether the preserved animals will really provide evidence of a perhaps completely new discovery. And if it was fluorescents were no longer visible in the specimens preserved in alcohol then the discovery would probably never have happened its not like were surrounded by living chameleons. But parts are lucky he found the fluorescent pattern around the skull in 8 out of 12 groups of known chameleons he investigated many different species have the patterns males more than females and the pattern differs from species to species. And the experts noticed Something Else the fluorescing areas are all located right at the tip of small bony bombs found on the lizard skulls. Is a clue researchers have always noticed these bony bumps or crests theyve been used in the past to tell species apart because they vary from one species to the next. Chris but the exact function of these crests has always remained a mystery to the fluorescents could provide a possible explanation for them because the pattern correlates exactly with these crests and bony structures on the head. A more detailed investigation of the small bony structures reveals that the skin covering the bombs is extremely thin practically transparent. Through these openings sunlight shines directly on the bones and they fluorescent light in the opposite direction. Fluorescents in marine organisms is a relatively well known phenomenon its been observed among 200 fish species as well as a number of sponges and corals but on land fluorescents has been discovered in very few animals now we suddenly find out the chameleons overall are more or less fluorescent animals that makes the phenomenon very special. Many chameleons species that display fluorescent patterns live in shady tropical forests where the proportion of ultraviolet light and undergrowth is relatively high and the animals for us on exactly those wavelengths. Its a range that potential enemies cant detect but one thats likely visible to their fellow chameleons. Research has shown the chameleon well towards the blue end of the spectrum. And they have sensory souls and their eyes that are sensitive to u. V. Blue is a very red color in the forest so a fluorescent blue pot would work very well as a medium of communication it would provide a constant signal for members of the same species and help complement the language of color which changes. An interesting theory but one that has yet to be proved for now the fluorescent patterns found in chameleons remain a mystery. Incidentally the quarry of victoria jellyfish is another creature that lights up right now and this one is relaxed but get it stressed and it will turn green to see the green fluorescent protein scientists managed to isolate the gene responsible when they injected it into the d. N. A. Of other cells they wanted to study they were able to trace the path of molecules or observe the growth of cancer cells that discovery even one them a nobel prize. Next week vacuum cleaners that operate on their own heating and refrigerator is controlled remotely by smartphone the internet of things is the stuff of the future but is it safe more on that next time join us then on to more are today. Well theme of the never more unequal than ever. Good. Provides billions in subsidies but the prosperity gal the Member States is growing. Why is this happening and what role does the euro play. And losers. Playing a cost on solidarity. Long. Odds. After the fall of the berlin. Not to my knowledge. Are we alone its a fundamental question of humanity trying to figure out whether or not. Life existed on mars pretty clear water was there a quite abundance while that would be interesting so on mars the atmosphere is 100. 00 of what we have here on earth its very very cold and at the past its like antarctica you could imagine bringing some supplies and you know if you do and build a little selfcontained pressure vehicle or vessel which would be on the surface there are things like oxygen that you can harvest from the atmosphere to help make living possible. If you want to think of humanity if we really want to survive for ever were going to have through off the earth eventual a i know that seems a little crazy but youve got to start somewhere.
