and derek williams joins us here in the studio to tell us a little bit more about the nobel committee's decision and why exactly they've received this prize tell us a little bit more about laser physics and what they've accomplished these are two fairly widely divergent fields but what they do have in common is laser physics ashton's work involved what are called optical tweezers so they allowed us on a micro he created a tool that allowed us on a microscopic level to to push around things like bacteria and viruses without actually killing them before them we had to actually kill them and fix them place in order to observe them so it allowed us to begin to observing these living systems which obviously had huge ramifications for fields like biology. on on the other hand the work done by more rw and and by strickland is it's about high intensity compact laser system so when you're creating a laser you have this problem with your amplifier the certain point the laser just gets so hot and so intense that it destroys it melts the fire they figured out a work around or on that called chirked

and derek williams from science is with us to tell us more about this decision hi derek did this come as a surprise to you actually kind of did because well first of all my predictions are never correct the first place but this was in my opinion this is still very early days in this technology so the technology of treating cancer the way that it can be used to treat cancer hasn't been around for all of that long a time and so it did kind of taken by surprise they certainly weren't in the front runners when you were reading the pundits online before ok so tell us about why their work is significant it is is it. significant work because. kidd the way that we treat cancer up until now we've we've we've basically had three different approaches either you treated it with surgery or you treated it with radiation you burned it away you there operated away burned it away or you treated it with chemicals chemotherapy and these researchers had a different idea the idea was why don't we try to activate the body's immune system to fight the cancer itself so it's a completely different paradigm it

derek williams is here to tell us a little bit more about this decision and to break down what exactly laser physics is first of all derek because i'm not aware are you surprised by the stripes well it wasn't really on anyone's short list to be honest it's also a very diffuse kind of an award it's laser physics is a very broad field in there and they're really giving it you know half and half to these to these to this task and to marie and strickland for really very different accomplishments in the field on the one hand with can you have he manipulates is. biological material with lasers so he's actually using it as a tool so advances in that particular field whereas the advances from ruin strickland date all the way back to the nineteen seventies when she was actually have a ph d. student and it's about it's about intensifying the. the rate at which lasers can be shown in tools and in order to make things so all in all there to really very separate areas for what's actually one of the most interesting aspects of this of this nobel prize is that strickland is is one of the first woman

definitely it's going to be a huge new tool in the toolbox for fighting cancer in the future derek williams thank you so much for that down. now today is international is the international day for the press and so we're going to take you to a radio station a thousand england that's run by the elderly for the elderly radio angels specializes in pre nine hundred sixty s. music and is run by dozens of volunteers most of whom are over seventy but for many of the first says around the world radio enjoy is about so much more than just hearing their favorite golden oldies watching one of the angel radios top presenters arrives at the studio in the southern english town of haven't. eighty six year old mildred french spins discs here the best of the thirty's forty's and fifty's. we don't put ourselves d.j. to be radio presenters d.j.'s a people talk over the top of records is something we can. make people request is something they need to hear it in total. mildred is one of eighty volunteers at the station most of them are over seventy she's played music here for eighteen years that when we were off

and we have derek williams from didn't you side with us to tell us more about the nobel committee's decision thank you for joining us the nobel committee said this is really a landmark in the fight against cancer why is that traditionally and there's always been three different approaches to kind of getting rid of cancer and they all came from outside the body there were surgery there's radiotherapy and there was chemotherapy so we were always trying to trying to destroy it from the outside now those all of those approaches together generally were not always effective or often weren't effective or they didn't get all of the cancer especially in patients where it had been task and so for a very very long time doctors have wanted to harness the body's own immune system to attack cantrips so but there are a lot of problems involved in doing that and these researchers managed to overcome those problems ok can you break down the key findings here in lay terms. the immune system is is an extremely complex system it's the immune system has to recognise cells in the body that are self that belong to

definitely it's going to be a huge new tool in the toolbox for fighting cancer in the future derek williams thank you so much for that take down. the pop star turned politician known as the wind has been hailed as the new face of uganda's opposition with his message of hope and freedom and inclusive it has built a large following especially among the country's younger generation but he's seen as a menace by long time president yoweri was seventy one was arrested on treason charges and says he was tortured while in detention in an exclusive interview with the wind describes his vision for a free uganda. world. that. he has legions of fans. both as a pop star and since winning a parliamentary seat last year as an independent candidate robert neeson time known to fans of the wine is a powerful opposition voice in uganda especially among young people frustrated by president yoweri museveni. just want to live in a country where all of us and all of us. no matter how you our tribe nobody knows you know what which from the new come from that's it can do one where i was just as gun feeling safe you

prizes to researchers who have done seminal work in their particular fields fascinating stuff derek williams breaking it all down for us thank you so much. germany's coalition government has struck a deal on immigration reform the plan is a first step toward more open migration laws designed to help fill a record number of job vacancies it prioritizes applicants education age and financial security the move aims to attract skilled workers from outside of the e.u. the focus is on immigrants qualification and the needs of the german economy the new laws will continue to differentiate between asylum seekers and economic migrants germany's economy minister paid to altmire spoke with kate brady about the new law. mr out my what exactly is the german government proposing when i say immigration based on the canadian model germany have a very pragmatic but modern immigration law the german economy is in an extremely dynamic state the labor market empty we need a qualified labor force this will be much easier on the future to recruit vali fight people in decent comando for german language with a good

right the nobel prize for chemistry awarded to three scientists for their work on proteins are derek williams thank you very much. now if you've ever attended or participated in an endurance race like a marathon you know what a mess they are to clean up especially at the water stops where hundreds maybe thousands of plastic cups and bottles clog the road the solution a company in london might be on to something. this little boy could save the streets and the seas from the scourge of plastic cups and bottles so-called. made from plant and seaweed extracts making them entirely edible and if they're not actually consumed the producers say great in four to six weeks at the richmond marathon in london the jelly like globe use went down a treat. runners and event organizers have long known what a pain plastic can be for them in particular these biodegradable drinking vessels are an important innovation regard they're. real like removing the bottles from the right because you just. throw it away. these weird little water bubbles are due to be trialled running events in the near future if they contin

congratulations to francis arnold george smith and gregory winter dark williams from our science department thank you very much derek. now britain's prime minister theresa may has called for unity in her conservative party tories are divided over may's approach to negotiations with the european union over leaving the bloc. now addressing at congress of her conservative party in birmingham england may repeat. position that the u.k. was prepared to leave the e.u. without a deal on free trade with brussels pressure is growing on the conservatives ahead of an e.u. summit in two weeks now out that some of the remaining twenty seven e.u. countries are expected to insist on a resolution over the issue of avoiding our hard border northern ireland and the republic of ireland. and let's hear a bit of what may have to say about the talks to leave the e.u. we are proposing is very challenging for the e.u. but if we stick together and hold on the i know we can get a deal that the british to thank what's go right to choose out of the congress and birmingham high burka i have to start with theresa make coming out onto the stage da

derek mois, was working 3:00 to 11:00 that day. the 911 call came in from tom hunter's dad, dr. william hunter. >> dr. hunter had come home, found shirlee sherman and his son deceased and would call 911. >> anything unusual about that call? >> there wasn't a lot of emotion shown, but he is a doctor. he is a pathologist. >> and he's seen a lot of dead people. >> and he's seen a lot of death, and it was i think to use a word clinical. >> reporter: the detective and his partner were immediately dispatched to the hunter's stately home in dundee. >> nice part of town? >> it is. it's -- it's an older neighborhood, middle to upper class homes, very quiet. it's not a place where we have a lot of violent crime occur in our city. >> reporter: even now, nine years later, detective mois still remembers the coppery scent of blood that hit him when he stepped across the threshold of the hunter home. >> there's a heavy metallic kind of humidity in the air almost. you almost feel its presence if there is a lot of it and there was a lot of it in the hunter household. >> reporter: to the left of the front door, in the
