Color of a warm welcome to you im on the thought she. First of it is have kicked off here in germany to mark the fall of the bull in wall kirti years ago on the 9th of november 1989 is germanys communist regime lifted strictures on its citizens leaving them feature travel to the west for the 1st time in nearly 30 years all this week events are taking place across the capital to mark the moment that changed history. History flashed before their eyes as thousands returned to prelims iconic aleksandr plots to mark their moment that would help change the city and the country forever. We want to make it possible to relive what happened back then and also the developments since then the road doesnt always been smooth over the last 30 years but we succeeded at something we can live together without a wall in peace and freedom in feeding on fire. On november 4th 1909 more than half a 1000000 protesters descended on the square staging what would become the largest demonstration in the history of east germany led by some of its most prominent intellectuals they rose up to demand more freedom. Is is. This is if someone has pushed open the window. After years of intellectual economic and political stock a nation good trial for the. Years reeking of apathy 4 years of double speak and bureaucratic despotism. What. If. The communist regime had rapidly and publicly lost all support but even then no one predicted that just 5 days later the berlin wall would fall. This week the spirit of the peaceful revolution once more lights up the city like this giant wave of colorful streamers at the Brandenburg Gate carrying messages of hope for the future written by germans. Over the coming days the city will celebrate the anniversary with more than 200. 00 events exhibitions and artworks culminating with the ceremony at the berlin wall memorial on saturday. Joining me now is the key lead the u. S. Team in the negev that brought about the reunification of germany after the fall of the bun and war of a well well continue this is a look 1st for tell me whats going through your mind as we approach this historic on a bus or a well theres a rush of memories about the the people have been in the people of east germany and the excitement of west germany but also the part that i was involved with was to try to deal with the International Context you had the challenges of the old for power rights after world war 2 you had 380000 soviet troops so the challenge at that time was how to mesh what was happening on the ground with the International Politics and we come to that challenge in just a moment for many of the form of the bulletin was it came as a complete and utter surprise did you see it coming you could start to tell in 89 that there was a movement to gorbachev and open possibilities the east german regime was shaky the exact prediction of when a wall would open was an accidental event of course so no one knew that for sure but you could tell that the ground was shaking they used to box in the negotiations leading to jim these reunification the socalled 2 plus 4 talks what was the most crucial part of that process and the challenges that you talked about. Well while people in berlin understandably and people across germany are focused on uniting of people from the east and west what has to keep in mind this was occurring in a larger context of stirrings in the rest of central and Eastern Europe changes in the soviet union and so one had to embed the unification of germany within the unification of europe and the key aspect of cliff do go ahead to go ahead to say so the key aspect of that was the success of the federal public of germany over 40 years and cold war had been its link to european integration and the Transatlantic Community through nato so at the same time we wanted to try to support germans and keep the promise for unification we want to do it in a way that would also reassured neighbors both east and west and so that the challenge was how to integrate it with what became the European Union and to keep a united germany in nato that wasnt so easy given the history of the sold war cold war with the soviet union i dont want that or this clear to us governments that germany should be and could be of united one day well that was the wonderful part the United States said had a promise to the german people youd side in the berlin airlift in 4849 you saw it with the opening of the wall in 61 and kennedys coming but the exact prediction of what could happen no one could know president bush actually in may so well 5 months before started to talk about the possibility of german unification so there was an interest in trying to support an ally but also do it in a way that build a future partnership and this is that it touching as after the fall of kabul and what this still is some degree of ambiguity about beautification especially and for my east germany what do you feel assessment. Well i know if you could see it at the time that was going to take at least a generation of change i actually drove through the eastern lender in 1902 with my wife just to get a feel for feelings on the ground i know a lot of the young people sort of came to the west but i guess one way of thinking about this in International Context is compared with the people of hong kong or the people of syria this was a movement on the ground but fortunately it had the support of its International Partners and it creates an opportunity for people for the future so you know history never is totally solved theres no end to history one has to keep working on these issues but it create an opportunity for the people of germany but equally important the people of europe and their connection in the Transatlantic Community robinson to thank you very much for talking to debbie on this important anniversary as the approach the 30th anniversary of the fall of the berlin wall great to have your insights and your perspective congratulations now one of the most dreaded aspects of life in communist east germany was the secret police the stasi it spied on cozzens of citizens many had no idea what information the stasi had gathered about them until ghastly to when their files been made available to the public we caught up with 2 women whose lives were changed by stasi and who still feel the effects today. This is the building where they used to live. When the 2 secretaries lived here in the younger years spies from the stasi used germanys secret police most of them through the kitchen window. But then the tree was smaller i was even busy do you see people from the stasi standing there no as for me i just recently read about it. We never would have thought of such a thing. No i dont think so either. They read about it in the stasi files a couple of 100 pages of intercepted letters private mail and official correspondence and most of all reports from spies including the layout of loners aber and zilker all files floods. At 7 am on april 30th 1980 observation of residence was undertaken to list the kitchen light was on and the window was half open and about 15 minutes later the light was turned off and save on left the flat alone she walked in the direction of the summer he touched us a subway station a zoo mother had someone looked into my life and i had no idea about it this is made me feel very uncomfortable for years i didnt want to have anything to do with it i didnt even want to read the file on the news as a star was there. But i have to live with it. In my experience you always get through life better if you can live with the situation with that. They wanted to leave east germany they had applied for exit visas it was here that they were subjected to hours of interrogation they never wanted to set foot in this place again. Well lets just go and you have to go back to the place of horror. But i have a really bad bottle a feeling really bad i could just cry then do it. Now. To this day they feel humiliated by the tone used in the interrogations. Through the system here. This is. So is a greeting it was like can see right away that your son is not only that of you better watch out dont even cross the street the wrong way we are everywhere just huge threats with you. That was more than 30 years ago on the anniversary of the fall of the berlin wall the stasi Documentation Authority made the files accessible fallen ilona zabel speak publicly about what happened there explain to young germans why they risked their lives to leave east germany. I wanted out and i didnt want anyone to tell me who has the right to decide where i live even if it were social or whatever but we didnt want that and at that age youre also brave enough to do it as much as most does he even somehow never getting out or only to a couple of countries that it was decided i could go to i never agreed to that i had said before that i wasnt happy with that and then i thought you know i just want out of here i want freedom he said if i had but at some stage it all petered out both women withdrew their exit visa applications. To pastor and that allowed her to travel alone as a boy had a baby and was allowed to go to the west after all. And all this week we had each of you will be bringing you special coverage and reports on the events which led to the fall of the berlin wall 30 years ago as well as stories of individuals as we just heard.

Not being able to pay and having to do without things to save money and its never ending in a source of distress. Fueled by a sense of injustice the protests show no sign of abating. Youre watching the news coming up ahead. Why is this man collecting elephant dung in south africa well its got something to do with something elegant cocktease in the pot as the sun goes down. But for us for decades scientists have been predicting really a would soon win the war on cancer but progress has been stubborn be slow and thats because a cancer diagnosis often comes too late when the tumor is already well advanced such a major conference on the topic in glasgow in scotland Early Detection is on top of the agenda. Breast cancer is often diagnosed through my ma graphy but mammograms are often far from conclusive experts have hotly debated whether large scale screening with the high tech method is the best way to detect the disease and its early most treatable stages in the race to improve early prediction oncologists have been looking for biomarkers and blood that indicate the likelihood of developing a wide range of cancers before they break out earlier this year in an announcement criticized by some a team in germany presented a marketable blood test for Breast Cancer its india india and its about liquid biopsy liquid biopsied means we are determining a diagnosis via body fluids it may lead blood. Einen boot we now have a blood test that enables us to find out whether there is an indication for a little lift and he or the opposite will be i did he see that theres no indication of ilyas. Now in glasgow new methods in the field where showcased that pushed the boundaries even further one of them as a blood test that might one day predict Breast Cancer up to 5 years before patients begin to show clinical signs another serving 50000 patients looked at predicting possible risk in Ovarian Cancer and the earlier the diagnosis the better the chance patients can be healed. And for a while im not joined by one of the authors of that study involving Ovarian Cancer got funston whos at Cambridge University welcome dr Feinstein Sim can you explain to us the potential benefits of blot test in diagnosing Ovarian Cancer. Yes so blood of. Potentially a very cheap quick. Simple way to detect cancer early in patients. The results of our study looked up to the use of one blood test called c a one to 5 to detect very in concert or in women with symptoms of come through such as blood thinning pin and we find it was a very useful test to help doctors identify the becomes or not group now until now screening for Ovarian Cancer hasnt been entirely accurate so do blood tests schauble promise screening is is a big challenge its very difficult to use a simple blood test to pick up accounts or screening focuses on patients with new symptoms or researchers focus on something slightly different weve looked at women with nonspecific very big symptoms of possible of our own concert such as blue thing and weve used the test in the patients and we find its very useful so that does sound promising but based on your research how reliable the tests in detecting cancer. So it varies on the type of tests used very very much. The tests we studied which is is currently used in the u. K. And some other countries. It picks up around percent all of our encounters it doesnt make them all up new task is ever going to be part of the picks up around 80 percent of those cancers and theres always been the hope for a long time that simple but effective blood tests would be available one day why has it taken so long. It takes a long time to bring a blood test from laboratory where its 1st creates is new ideas are developed always 3 to using them in patient care the majority of new. Biomarkers you see on the new used the new c. Reports it will never make it to the patient so this requires decades of research some times to shew that these tests were there affective and that we can use them in patients without causing harm thats a long process but its really important a necessary process right got funds to the Cancer Research at Cambridge University thank you very much for sharing your expertise with us and. Now this is a majestic animal and elephant elephants produce huge amounts of something thats not quite so majestic poop elephant dung is use for
