Before the whole case is decided lets talk a little bit more about that yes and you already referenced a potential break up what could this mean for big tech and consumers because it is a breakup now inevitable. Well it just by far not decided and if you look at the reaction on no wall street so that also tells you a little bit of the sentiment the stock off alphabet so the Mother Company of google is make julie even gaining a bit in todays session so wall street does not seem to be too afraid at least for now that anything will change anytime soon but on the other side google clearly is the guinea pig here because there is a lot of scrutiny on the other big tech giants who also have dominant in one of politic. Positions in the tech world if youre seeing Companies Like Facebook Like apple like amazon for instance so all of them they will very closely watch that case and if they google would lose that could make it easier for lawmakers to old also go after some of those other tech giants yes quarter reporting from new york thank you.

Nigeria has imposed a 24 hour curfew in the commercial tapper lagos as protests over Police Violence have rocked the country the police chief announced that riot police will be deployed across the country to help quell the unrest while young nigerian is have been taken to the streams for the past 2 weeks over abuses by the polices notorious special anti robbery squad the outpouring of anger forced the government to scrap the unit a week ago and problems with forms of protests have continued to swell as demonstrators demand more sweeping changes. Ok lets take you straight to our sunday fish are in lagos funny why this curfew right now. The latest state governor tweeted today that there is an arc industry chaos on the street and in order to bring back law and order what is needed right now hes in a state is a cook curfew that is going to last for 24 hours he said literally that the protests that have begun as peaceful protests have quote generated into a monster and you can well imagine that this didnt go well dont well the protesters who are as im speaking right now gathering in france right now very very close to our studio because they say well if theres a curfew that means you have to stand and stay where you are going to curfew stars so this thing they just go where the protests are taking place and just not move for 24 hours until the curfew is in place so clearly they dont want to stop the protests and they also make the government responsible for this criminal elements that are mingling into these demonstrations they say that they are sponsored by the government to bring an end to these protests by a curfew for example as we see developing right now and a funny tell us about these protests what are they about. The old regional goal to say it was really true and Police Brutality. By the soul of a police unit known as a source of a racial war that police cannot grant down on the very civilized people who are just going about their daily lives but now almost 2 weeks into the protests the protestors say well if you have achieved as sars has been the sole then maybe we can achieve even more because they say the solving sars doesnt mean that things have come to an End Police Brutality is still a huge issue across nigeria so the protesters taking to the streets because they say enough is enough on many levels not only when it comes to Police Brutality but when it comes to abuse of power and misuse of power in this country per se right and as you reported were showing pictures of crowds gathered to define that curfew what are the nigerian authorities doing about the sars police unit. There were a few things today i was there over said well thats quite unprecedented unprecedented for example is that authorities that the government the National Government that they actually apologized and they said that what happened so far it comes to Police Police responsibility wasnt the right thing the police is supposed to protect the people and not be violent to them so they apologized they said theyre going to be sold stars theyre going to replace it with a new you and swat theyre going to bring panels into other countries that are going to transparently make it open to everyone that changes taking place in this country but as i say again protests to say theyre very skeptical in fact whether this momentum that they have achieved so far is going to trickle down in real action when it comes to these changes really being put into action so they continue to take to the streets to make sure to ensure that they can hold the government to their promises accountable and start reporting from Lagos Nigeria thank you. And there has been more fighting and tatchell to is reported in and around the disputed nagornokarabakh region in the caucasus both sides armenia and azerbaijan accusing each other of targeting civilians in the flare up and fighting that began 3 weeks ago our correspondent youll be on reports now from the city of down in azerbaijan as areas already say a missile attack by a 1000000 forces there still a dozen people and injured 40 over the weekend. On the ruins of what used to be her life. Her neighborhood was destroyed in the missile attack over the weekend. For home 3 years. This is from where the rocket came there were houses everywhere here but they were hit and everything got destroyed. The small Sports School to. Look they were close and mattresses lying around my belongings also somewhere here. Next to the bone down homes a makeshift memorial. Many ganja residents come here to commemorate those killed in the attack certain people according to the authorities. They bring flowers and sign saying who they blame the army an army. To rest in peace gunja people may god bless you. The city of gun julys dozens of calle meters away from nagornokarabakh people who live here never thought they would become part of the fighting but they were wrong several houses in this residential area have been reduced to rubble over the weekend and its become clear once again that this conflict can escalate any time and an end. The direction. Since late september amenia and as a by john have been a dwarf a nagornokarabakh again. And it is difficult to get an independent picture of the situation in the region both sides report military successes both countries accuse each other of fueling the fight in. 2 attempts at a cease fire have already failed propaganda and war rhetoric determine everyday life. Also here in the city center of gun jeff most people we speak to support the war a positive i dont want to see with the power and strength of our army will soon be taken and the flag of azerbaijan will be erased that although much of our registered as a woman to join our army im ready. This clearly has been changed we are not afraid or even my family and fellow citizens all of us so willing to sacrifice our life for a nation we will never back down just folks like what it is because im up for the old us after the fatal attack on gun just as a by john has the right to defend itself many here say. He now has to look for a new beginning in the ruins of her own life so you have to. Mine an hour of the top story that were tracking for you. The u. S. Has filed a landmark Anti Trust Lawsuit against the tech giant google it alleges that google of used dominance of the worlds leading Online Search engine to maintain its position ahead of. You watching you know it is from growing and the stick shown to the moments of Business Update with Kate Ferguson and over that you can get all the latest news and information on the mountains had to a website. Dot com rock on to help with the entire thanks for spending part of the to. Combating the corona pandemic. Where does research stand. And what are scientists learning. Background information and. Our corona. Covert 19 special next on w. I was issued when i arrived here i slept with 6 people in a room. It was hard i was free. I even got white hair. Learning the german language. This gets me and pick up a notch maybe to interrupt its the thing you want to do their story my parents are fighting and reliable information for margaret. How dangerous is the air around us. Every time we speak every time we laugh or sing. We admit its particles and once theyre there they linger we know that this is a key way that corona virus can spread. Scientists are still sussing how dangerous these doses of airborne virus can be and what we can do to avoid them. Opening a window is one way to keep their fresh but by keeping the air moving with systems like air conditioning or we decreasing the risk or merely spreading it. What do we need to do to breathe easily indoors. And this is the covert 19 special hello and welcome to the show im in berlin open the window its the one piece of advice were all hearing now thats a bit more complicated in the winter doesnt work in all rooms and certainly doesnt work on airplanes theyve industry says cabin air is sufficiently filtered and circulated to some experts to questions remain. For air travelers social distancing already starts to get difficult at the boarding gate and it gets even trickier on the plane spacing out just isnt possible unless you can afford to buy an extra seat. With only 50 centimeters distance between each person the risk of infection is obvious and healing the droplets in aerosols from an adjacent passenger seems unavoidable scientists have long been aware of the days. Injuries of infection on planes mostly because of studies of other coronaviruses air is not displaced in aircraft inlets and outlets are too small for that cabin air can only be mixed. Over at the Hamburg University of applied Sciences Professor dr short says viruses may stay in the cabin air for up to 15 minutes exposing passengers to infection risk. We are going to want to look for the Aviation Industry makes 3 climbs firstly filters an aircraft to make the air as clean as an operating room for them secondly the air is completely exchanged every 2 to 3 minutes thirdly the air only moves from top to bottom in the cabin all 3 are just not sure. It could be that current Safety Standards and filtration techniques are not as good as many may think meaning the possibility of catching coronavirus when flying could be more up to chance than anything else. Lets take a closer look at ventilation and the virus joining me now is paul linden hes professor of fluid mechanics at Cambridge University paul its good to have you on the show sort of the obvious question winter is approaching in northern in the Northern Hemisphere whats the best thing that someone should keep in mind about ventilation in rooms well its obviously a challenge to winter because. You have been so used to close up buildings and ventilation is reduced to keep warm so the best thing to do is to make sure that as much ventilation as possible is that you open a window if you possibly can. And if you have a mechanical system make sure as much fresh air coming in as possible what about fans what if i just have fans that are standing around the room does that help keep things ventilators that help me at all. No it doesnt it will just mix up whats already there and thats probably not the best thing because if there is a virus particles in the out in the air and start all around your chances of breathing them are increased so i wouldnt recommend using fans ok so the best option then it seems to be is to keep the window open even though its when its winter early to open a periodic lee. Of course thats going to mean that people are going to be colder rooms are going to be colder is this really a choice now that we have between Climate Control and being safe with the virus is it such a black and white choice pretty much i would say it is thats right and. Its well known that during the spanish flu. Crosses in the u. S. Even in the midwest in the winter were held outside so its. I think it is a it is a tradeoff between staying warm and staying safe. Thats going to mean quite a change for the industry the Climate Control back air conditioning industry yes absolutely it will and i mean conventional systems use a certain amount of research connected air and they supplement that with some fresh air when its pumped to doctor through the building and again you want to make sure that the proportion of pressure air is as high as possible and that will in a Climate Controlled situation mean of course the more energy is used to keep that to warn that iraq. So it will be a tradeoff they have between between energy costs and. The amount of fresh air that you can provide. And then one of your studies you mention Carbon Dioxide of course being an indicator as well does this mean that we can expect that Carbon Dioxide measures will be a more common feature in rooms. I believe thats a very sensible thing to do Carbon Dioxide is essentially within a building produced by people exhaling. And so levels that are about the background outside values of about 400 something past a 1000000. Indicate indicative of. Being in someones lungs and then breathed out again and so measuring that gives you an estimate in fact you can relate the risk of infection directly to the concentration of Carbon Dioxide help me understand your picture when i enter a room breathing speaking laughing with without a mask what am i seeing and what are you seeing if youre able to see these these plumes or whatever you call them. Yes so from an individual you give off heat. Every person gives off about 80 watts bit like a blot fairly bright light bow and that heat rises from your body in what we call a turbulent plume. And that will rise up to was the ceiling and you know that in most rooms the air in the ceiling is warmer than the air in the floor also plumes arise from equipment like a computer or other things and when you breathe out you also breathe out warm air and that warm air is directed of course in in Different Directions so if you breathe through your nose its directed downwards if you breathe if you talk and it goes nationals horizontally and of course it depends on the sounds that you make some sounds inject air further and louder you speak the further it goes so theres a very complex dynamical process going on and its invisible thats quite right we have techniques that make it possible to visualize this and we use those techniques which essentially look at the way the refractive index of the air changes its a bit like watching the air shimmer above a toaster you look at your toaster one that you see that is the same process and we can visualize that we can see where this goes and what we do see is that if you wear a mask for example that the air that you exhale even when youre speaking were even blocking and coughing tends to basically leak around. The edges of the last nights sleep around the nose where it doesnt fit properly and that then gets carried out with the plume in your body and thats a good thing so that so wearing a mosque generally confines your breath to to be taken up with the hot air rising from you is more complicated if you. And youre around on the other hand because then you have a wake behind you just as you would. A way behind a ship and and that way you carry your breath in the wake behind you so you can spread it around quite significantly so those flows are much more vigorous than the flow produced by your ventilation system unless youre very close to say an open window you probably dont perceive the around you. So those floods are run through the week the flow from your heat from your body when you speak when you breathe in and now theyre much stronger and theyre and so its a complicated interaction between those flows and the general tendency of pot in to rise and and to be taken in and out through whatever openings you have in you in the building or i will have to leave it there for now it sounds like a fascinating time to be a professor of fluid mechanics paul linden joins us from an imaging averse they thank you very much thank you. And now its time for your questions its the part of the show where our science correspondent Derek Williams answers the questions youve posed that tore you tube channel over there. If a number of vaccines come out of the same time would it homy to take multiple different vaccines. In light of how quickly things are moving on the vaccine front this is an important question to ask for example there have been reports that china is apparently already giving tens of thousands of doses to people there of vaccine candidates that havent yet completed widespread safety and efficacy testing observers are seriously alarmed by that because it sets the stage for a range of frightening possible scenarios what happens for instance if the vaccine doesnt prevent infection as well as hoped and and those people have to be vaccinated again at some point with other candidates could that be dangerous for them the short answer is once again we dont know but possibly vaccines can have adverse effects even when just one is administered thats why theyre tested so widely before being approved for the general public and with dozens of different candidates out there based on a number of different platforms there are a lot of possible combinations with the potential to go wrong if people start being given more than one vaccine or were given them in haphazard undocumented ways until we actually do it theres no way to rule out that giving vaccines in combination or in a series could pose a danger which is why its best to exhaustively check every vaccine candidate for safety and efficiency in advance so that in a best Case Scenario we only have to vaccinate everyone once. Or science correspondent there williams there and before we let you go heres another look at how people are adapting to life in the pandemic in this case by socially distancing within a crowd.
