Nobel prize for medicine goes to a trio of scientists today groundbreaking work on oxygen levels and sell their research has changed the way humans fight cancer and other diseases. Plus pounds of street performers from the all over the world converge on a tally in town to do some clowning around. Im headed home for a client he could join me us President Donald Trump and his plans to pull u. S. Troops out of syria assuring far from both sides of the on in washington senior congressional politicians according on trying to reverse his decision theyre concerned that the pullout will allow turkey to know which is long planned offensive against kurdish fighters in the region fighters that have been key u. S. Allies in its fight against the socalled Islamic State. Leaving in a hurry american troops started pulling out of syria within hours of the official announcement. They leave behind them empty bases near the Turkish Border bases that had been a guarantee of safety for Kurdish Forces u. S. President donald trump abruptly canceled that guarantee by tweet the kurds fought with us but were paid massive amounts of money and equipment to do so they have been fighting turkey for decades it is time for us to get out of these ridiculous endless wars many of them tribal and bring our soldiers home u. S. Troops were in syria to support Kurdish Forces in the fight against the socalled Islamic State but turkey has long resented the presence of kurdish paramilitaries near its border it considers them terrorists kurdish groups in the region have protested the move they feel abandoned by the u. S. And they fear a turkish invasion is imminent. I had the this green light the trump gave her the one will actually complicate the crisis in the region. And. It will provide Islamic States with an opportunity to regenerate and control areas such as russia and terrorism or again the. Turkish president recha Tayyip Erdogan gave the kurds a stark warning that suited there is a phrase that we always say. We can come any night without warning and our determination remains because it is absolutely out of the question for us to further tolerate the threats from these terrorist groups. The International Community has raised serious concerns and you would arm for stupidity in the north east with not only exacerbate civilian suffering can be too massive displacement but when or so reese can see the early undermining current political efforts we treat as you know support there 6000000 displaced people inside syria more than 5 and a half 1000000 refugees in the neighboring countries and its a conflict that has gone on for far too long and therefore any operation that takes place at the moment has to take into account to ensure that we dont see any for the displacement thats on the ground in syria kurds are waiting for the next blow to fall in a region thats seen its share of misery and violence already. Well situation has become even more confused just chump issued a right to attack you know he tweeted as i have stated strongly before just to reiterate if turkey does anything that i and my great and on much wisdom consider to be off limits i will totally destroy and obliterate the economy of techie. Our correspondent in turkey you han has this assessment now. U. S. President trump sudden decision to pull back american troops from north and syria has provoked an angry response from syrian Kurdish Forces in the area for a long time they have been considered not only by the u. S. But by many countries as the most Effective Group in the battle against the socalled Islamic State the kurds have lost thousands of fighters in this battle now theyre accusing President Trump abandoning them and leaving them exposed to a Turkish Military assault the turkish government on the other hand has long pushed for a military operation in syrias north east because it considers the Syrian Kurdish fighters that terrorists and the threat to turkeys National Security turkish president of add one also says he plans to resettle at least 2000000 Syrian Refugees in what he calls a safe zone but many questions remain on oncet it is unclear for example what scope this Turkish Military operation might have and when it might start our correspondent there reporting from turkey and i will prize for medicine has been awarded to 3 scientists from the United States and britain and they were chosen for their pioneering discoveries of the way blood cells scents and adapt the bodys oxygen availability is the 1st prize an ounce by the Nobel Committee this year nobel prize in physiology or medicine jointly to with caitlin sir Peter Rockliffe and greg gets amounts. This years winners of one of the worlds highest profile awards worked for the most part independently of each other the announcement caught them unawares. And at that point i think it was just so surreal and i sort of had this out of body feeling of just great appreciation and i got to start so thrilled to share this with all the people who have met meant so much to me in my life well to life to all in a little bit surprised at this morning yeah hi i have a deep sleep 1st. I could wake up eventually but by the time i got to the phone it was too late and so i said to myself i wonder if this is somebodies idea of a bad joke in the middle sort of the 3 scientists were chosen for their work on how cells sense and adapt to oxygen the gas is a key part of converting food to energy but oxygen levels can fluctuate dramatically in the body. When you exercise climb to high elevations or are pregnant the oxygen levels available for metabolism go up and down to keep functioning the bodys cells have to be able to adapt to these changing levels kalends amends and radcliffes work covers details of the mechanisms that regulates that adaptive process but i would say the benefit is understanding these fundamental mechanisms but the Practical Applications are yet to come and thats why she works then tries to see discovery that it will then sell for so many possibilities and then you create some new research and yes for example in healing wounds or in treating patients who suffer from severe anemia or even cancer. With their discovery kalen ratcliffe and samantha have laid the groundwork for a whole new era of Drug Development one that is now starting to address conditions that modern medicine seeks to heal.
