doctor tim lamont from the university of exeter was the lead researcher of the study. we listen, the weirded it gets. weirder it gets. in almost every time we go out, fish can make more in weirder and more diverse sounds than we ever thought before. sound is a very important part of the lives of any underwater animal because sound travels so well underwater. these animals are using central also to things in these animals are using sounds essential to things in their everyday life and so commence from the here are them defending the territory, some of them are trying to attract a mate, some are communicating with each other. and so it's really integral part of the ecosystem and that means by listening into this ecosystem, we can understand more of this thing than if we look. that's all for now — stay with bbc world news. hello again. storm barra of course has been dominating our weather picture over the last couple of days with strong winds, heavy rain and some upland snow as well. but look at these big rocks. the seas have been chucking them onto the coastline of west

back into risky territory. dots about ups punk, honeywell is from the university of exeter medical school. he questions the u. k. government's approach to containing the virus. they saw a lot of confusion and concerns the way it was suddenly announced on a sunday i pre recorded message, and i personally feel that prime minister johnson has once again got it wrong. let me explain why. prime minister johnson continuously continuously continuously keeps on talking about one thing only, which is boosters, boosters and business. if you were to take the advice from any scientist, any scientist worth their salt will tell you that one way to keep the infection numbers down case numbers down is a multi layered approach. the multi layered approach with prime minister johnson just doesn't want to do is where your mask very properly, where a good quality must work from home. cancel parties, stop gatherings in pubs and restaurants. have your boosters have your seasonal influenza vaccine do? so it is multi month multiple approach that is needed on we crohn is may be a little bit vaccine, evasive. howev

dr. parrots, pakenio is a senior clinical lecture at the university of exeter medical school. he says, the army kron variance is exhibiting some concerning traits. it is significantly more infectious. also, we've learned that it bypasses the antibodies made by the vaccines cause for the occurred bit that we are not 100 percent sure about is, is it less disease causing universally in south africa? we noticed that it is less disease causing, but there are lots of things that would explain it, which is younger population, several of bouts of infections gone through the population, etc. so what we really want to know is in the older population, in other parts of the world, is it more disease causing? and if so, what are the additional precautions that we should be taking? the strategy, the united states has taken is test test, test and test the europeans are taking the strategy of test and isolate and need other parts of the world. it is, for example, in the far east, it is serious, assiduous, compact, tracing, and isolation of cases as well as the contact. so there is a differenc

, you know, washington i on, i spoke to dr. bark on connie, our senior clinical lecture at university of exeter magical school told me why the data coming in from different countries might seem confusing when we try to figure out the severity of the crime. our data is always muddled up with the findings from south africa. so how long will it take? another 2 to 3 weeks is when that lag time between generating cases and hospital admissions will start to appear. and then another couple of weeks more will start to tell us if this is as severe disease causing as the are the variance. so unfortunately, we do need that time. and whilst we need that time, we just cannot afford to sit idly and do nothing. that's why countries like, for example, holland are taking immediate actions to have a shut down and reduced number of cases. south africa has a predominantly young population and we do know that the sauce covey to waters is seriousness of serious illness is the older you get, the greater the number of apologies you pick up as you grow older. the more severe disease causing it can be, therefore, in the

some doctor by rat pang carney i who is a senior clinical lecturer at the university of exeter medical school. he joins us from bath by sky. thanks for being on the news. our doctor. its almost been a month since we have been living with the army con, it's gone so quickly. what we've learned in that time about this new variant. we've learned quite a bit and there's a lot more to learn the bits that we've learned all the asleep, give us some cause for concern, which is it is significantly more infectious. also, we learned that it bypasses the antibodies made by the vaccines cause for the current bill that we are not 100 percent sure about is, is it less disease causing universally in south africa? we noticed that it is less disease causing, but there are lots of things that would explain it, which is younger population, several oh bouts of infractions gone through the population, etc. so what we really want to know is in the older population, in other parts of the world, is it more disease causing? and if so, what are the additional precautions that we should be taking? i guess there's

i was a senior, a clinical lecture at the university of exeter. as medical school. he says, unless poor nations are fully vaccinated, which are nations immunizing, their population multiple times will not stop variance emerging. every little controlled exposure to the wireless is proteins enables your body bodies immune system to be reminded and then reminded again that you need to make immunity against me. and more importantly, that remember me in other words, immune memory. so of course, it makes a lot of biological sense that a 4th and may be a 5th vaccine out would be beneficial in that it augment the immunity. having said all this, there is, of course, a concern that we need to do also immunize the rest of the world to we need to immunize people who have not had any vaccines at all. because that is where the greatest public health gain comes from. again, this is an example of the richer nations can do whatever they like, because they've got the vaccines that what the supplies and they can immunize their population once twice christ. and now the 4th time, the tr
