In the village of upper enham. The suspected attacker fled on a motorbike and was killed in a crash three miles away. The Indian Ocean Island of mauritius has declared a state of environmental emergency as tonnes of fuel spill out of a ship that ran aground in july. The weather is forecast to deteriorate and there are fears that the japanese owned mv wakashio could break up, leaking more diesel and fuel into the Pristine Waters off pointe desny. 400 sea booms have been deployed to limit the spill. Now its time for a look at the weather with alina jenkins. Hello, another warm if not hot day for england and wales, a bit cool gcioss for england and wales, a bit cool across Northern Ireland, scotland on the north of england. Sunshine around for most of the rest of the day but there will be more cloud feeding in to eastern and North Eastern coast of england, parts of cornwall as well hanging on to more cloud. Highest temperatures across central and southern england, 35 or 3a celsius across south east england, the high teens or low 20s further north. The area of low crowd in the north sea starts to push its way westwards, some misty and murky conditions, perhaps some showers late in the night, another very muqqy late in the night, another very muggy night for many, away from scotla nd muggy night for many, away from scotland and Northern Ireland, temperatures across southern england may not drop much below 20 celsius. For many of us tomorrow, we may not start with a lot of cloud, misty and murky conditions, a few showers cropping up through parts of the midlands and northern england. At most, a mainly dry day, the cloud will thin and break so we will see some sunshine again, the highest ten bridges across central and southern england. Hello this is bbc news. The headlines. The ministry of defence says its had a formal request to help the home office, as it steps up efforts to reduce the number of migrants crossing the english channel. A big Anti Government protest is underway in beirut in the wake of tuesdays massive explosion. Marchers are making their way from the devastated harbour area to Martyrs Square in the centre of the city. Clashes have already broken out with Police Firing tear gas to stop demonstrators getting to the parliament building. The use of face masks in england and scotland is expanded with coverings now compulsory at cinemas, museums and places of worship. Stricter lockdown measures are reinforced in preston following a spike in cases in the city. Now on bbc news, Philippa Thomas hears from people around the world about their extraordinary experiences during the pandemic and how covid i9 has changed their lives. Welcome to coronavirus your stories, a programme about how covid i9 is affecting the lives of people around the world. Im Philippa Thomas, and this week were hearing inside stories from scientists, some of them directly involved in the fight against the virus, others using ingenious methods to carry out their research while working from home. Later, well hear what its like to be leading one of the global teams trying to develop a vaccine. Well find out how Students Learning online with the Uks Open University can remotely conduct experiments, programme robots, even point a telescope to the stars from a spanish island. And we start with two Young Research scientists who answered the call for expert volunteers as the uk faced its own pandemic emergency. Abigail perrin and Jessica Olsen both work at the renowned Francis Crick institute here in london. My normaljob is looking after malaria parasites and working out how they live and grow in human red blood cells, so i think in early march time, there were lots of e mails flying around various channels asking for people who had experience working with infectious diseases, who had the necessary training to handle potentially infectious samples, and myself and my colleagues here at the crick who had that experience have been helping with that first step in virus testing, which is just to make the samples we receive from patients and other people who are tested safe to go upstairs to the fifth floor of the building to actually have a coronavirus test. That sounds pretty crucial. Jessica olsen, you also answered the call for volunteers. Tell us what youve been doing to help with covid i9 and where your skills came from. So, usually at the crick i work in a team where we produce genetically edited animals and cell lines to the rest of the laboratories to study human disease and development and the functionality of genes. And so, when the call came out in march, i put my hand up, because prior to working at the crick, i was a biomedical scientist at Royal Marsden and actually began my career in new zealand in a virology lab, which i loved. So, when the testing started, because the crick is a research facility, they needed people with the appropriate clinical accreditation to release those patient results to the patients, and thats where i stepped in. And jessica, what did your family back in new zealand think about the fact youre stepping up to the front, as it were . I think they were very proud of me. My specific part of the pipeline is at the very end, so often im staying up in the evening till 10 30pm at night waiting for the last results to go out to the patients. It has been a time that has been a lot of late nights put in, but at the same time, its been rewarding work to do. Both of you, but i will askjessica first, i suppose this is work that is going to have to continue. I mean, only this week, we have been hearing about the fact that the uks test trace system still needs to come up to scratch. Theres a lot more work to be done. Yes, yes, and since march, we havent stopped. Were constantly improving the service we give and kind of keeping the longevity of it going in case there is that resurgence, which seems to be happening, and its something we are planning to do for as long as its needed. And, abby, how has it made you feel, the fact that were all now talking about science and theres perhaps a new found respect for scientists as well . Well, id love to see that continue. I think weve gone through a sort of strange and uncertain period where theres been quite a lack of trust in science and evidence, and i hope that in this time, showing that scientists can come together, pool their skills and do something valuable for local communities, but as well more globally, might restore a bit of trust in science. We live in very Uncertain Times, and the best way to combat those Uncertain Times is with evidence. And we can learn a lot from studying the world around us, and i hope that during this pandemic, thats become more obvious. Its actually been quite a nice wa ke up call for scientists that perhaps were a little bit more adaptable than we sometimes give ourselves credit for, because we usually focus on a very specific area of science. And actually, most of the people who worked on this testing pipeline at the crick have very little background on virology but in just a few short weeks, we combined our expertise to manage to put this together in a way that has been really effective, and i hope that we as scientists learn from that. At this time, were seeing scientists who usually work on completely Different Things applying their skills to fight coronavirus. We can learn that we can expand our horizons and use our skills and our training to apply ourselves to lots of different problems. And if i could jump in, i think its been a time with science has been put in a positive light and scientists are having the chance to communicate in a way that is digestible to the general public, and i think for me specifically, my friends have started talking about pcrs as if its every day terminology, and thats something we can give to the general public in a time like this, which has been very positive. And just talking about dealing with the unexpected, i want to put to both of you the idea, do you think as experts it was possible to see a pandemic coming . Do you think there shouldve been more done to listen to voices from science . I sort of reacted a bit when you described us as experts, because most of us dont feel like an expert most of the time. These are massive, complicated global problems with lots of different types of science thats needed to solve them. Whilst we may may be more expert in science than the average person, actually these are really complex problems, we all need to Work Together to solve them. Perhaps, abigail, we all need to learn to be more comfortable with uncertainty, which involves a certain humility . I think thats what being a scientist has taught me more than anything is that theres so much we dont know. We just need to become a bit more comfortable questioning what we think we know and using that uncertainty in a positive way. Jessica, on that matter of uncertainty, here i am as a member of the media, and the media often deals in headlines, but as a scientist, youre especially aware of the complexity of things and the uncertainty of things. And i wonder what you think about that tension between headlines and complicated realities. Yeah, i mean, its definitely there, and i think thats one thing we could probably all collaborate a bit better on having been through this pandemic. Is going more for the facts and working together as media and scientists to give Accurate Information out to the public so that they become aware of the situation without being scared of the situation. Scientific researchers Jessica Olsen and Abigail Perrin of the Francis Crick institute here in london. Now, if we talk about remote ways of working or of learning, the uk based open university probably got there first. Its just celebrated its 50th year and now has about 168,000 students across europe and beyond. And part of what the ou does is called the open stem initiative. It allows Remote Access to all sorts of things, whether chemistry experiments, robotic engineering, even the ability to operate a telescope to look at the stars from a spanish island. Ive been talking to the director of the open stem lab, helen lockett. In the early days of the open university, we wouldve delivered Distance Learning through home kits, so students would have been sent those through the post, they would have used that kit to do engineering chemistry experiments, and worked that way from home. But of course, technology has moved on and our courses have got much larger, so for the last ten years or so, weve developed this Remote Technology called the open stem labs. I remember those kits because thats how my father took his degree. He used to have chemistry equipment and geology samples arriving through the letterbox on a regular basis. But now, of course, you seem to have the kind of learning, helen, the kind of techniques that are just right for lockdown . As soon as covid i9 came along, weve had a huge number of enquiries from other universities who are unable to do their conventional way of using labs face to face, where usually students would go into a classroom and be in a large ish group with a tutor, and that has not been possible under lockdown, whereas in our remote laboratories, students sit at home and use their laptop, and they are connecting to real equipment from home, so that might be a telescope or microscopes or electronic equipment, really any kind of scientific or engineering experiment. Im going to have to pick up right away on you saying telescopes. What do you mean . Well, the open university has an observatory on the island of tenerife, one of the ca nary islands. We have fully autonomous robotic telescopes there, and a student can sit from home and as part of their astronomy course, they can connect to those telescopes, choose where to observe in the sky and take imagery from the telescopes. Its really amazing. I understand students are able to do experiments using microscopes, very specific and delicate equipment. Thats right. We have real remote microscopes, so the microscopes sit on our campus in Milton Keynes and students can connect to those from home. So, students might be studying the eye of a fruit fly, sitting at home, controlling an electron microscope elsewhere in the laboratory and looking at a real fly in tiny, tiny scale. And there are a lot of areas of innovation which draw a lot of interest now. Im thinking about robotics, for example. Are you actually able to programme robots from home . So, weve done a little bit of that. We have some robots, and thats something were building up. We do something called lab cast, which works quite well, so a tutor sits in a laboratory and demonstrates a robot, and students interact with that from home, learning about robotics in that way. Now, you said at the beginning of our conversation something about the interest youve been getting. Where have the calls been coming from, what kind of countries . Well, all over the uk, lots of universities saying, our labs are closed, and can you help us, what could we do to allow students to do practical work from home. We have had enquiries from as far away as australia, india, countries across the world, really. Its been quite hard for us to cope with the demand. I know from conversations ive had with other universities, notjust in the uk, but internationally, that funding, that finance is a big issue now for the future. For students and for lecturers, the universities themselves. Do you feel that Remote Learning is going to have to play a much bigger part from now on . Well, i think it is interesting that initially we thought universities would only be interested in the short term in switching to a remote site model. But i think, as you say, what weve found it they see it could be potentially useful in the future, because students could have smaller laboratories, you can use your equipment more efficiently, so that blended model might work into the future to give a better experience for some students than they would get in the traditional model. And just a final thought, have you felt that professionally youve been in the right place at the right time . Its certainly been an interesting time i think we feel incredibly lucky that our Distance Learning model at the open university has really protected us from the covid crisis perhaps much more than other universities, weve still faced lots of challenges, but things working with groups from china and korea, to australia to the british nhs, the wistar inovio vaccine is a synthetic dna vaccine that isnt based on the live material, but copies it, essentially fooling our immune system into believing that covid i9 is present and needs to be repelled. The aim is to inject an artificially created version of covids viral protein into the body as genetic information. That, its hoped, will stimulate our immune systems to create their own defences against a virus that can do so much harm. Leading this particular effort is dr david weiner. He is executive director of wistars immunology centre. He has worked before in the fight against deadly viruses, from sars and mers to zyka. Hes been talking about how this one feels very different. Since its happened upon us so fast, and were really learning on the fly, were essentially building the aeroplane to control this while were trying to take off and control it, and thats an enormous challenge. We dont know much about its background, where it came from and then how to protect against that. But we are learning a lot. Weve made enormous progress. I want to talk about your family, because i think you also have personal reasons to hope that this works, that mitigation and a vaccine is brought to the fore very quickly. Your daughters a doctor, yes . My daughters a physicians assistant at the mayo clinic, and shes in emergency medicine. Im very proud of her, and so shes of course been seeing patients with significant amounts of disease, and, yeah, so thats a very important thing and a very big. We think about that a lot, of course, and i also have a Family Member who is immune suppressed, so we have a lot of personal concerns that way, but i think every family does. We are all seeing people we know who are getting sick, etc, with this disease. Its important to say that though im speaking to you in pennsylvania, this is a global effort. You have testing in south korea, and youre working with scientists across borders. Thats correct. There is really a much larger effort than us. Were only a part of the programme. The programme is funded originally by the coalition for epidemic preparedness innovations, which is a Global Outreach Programme with funding from the department of defense and supported by other agencies and also by the bill and Melinda Gates foundation, and of course, it has a company lead, which is how the programme is set up, which is in pennsylvania, the California Company inovio, and we have collaborations across the globe, such as Public Health england. Ill ask you to explain, very much in laymans terms, what kind of vaccine you are working on. Im sure our audience know there are different types depending on whether youre injecting live material or not. So, our vaccine approach is an approach we have worked on for several decades now, which is the idea of delivering nucleic acids. Dna, and you have also heard of rna vaccines, both nucleic acid type approaches. These are nonlive pieces are basically encoded information, and this is a new concept in vaccine development, and these are nonlive. They dont grow, they cant spread. Theyre delivered locally in the case of the dnas in the case of covid i9, into the skin, and that local site where the skin then tells our bodies cells to produce a single virus protein that has been designed on a computer, and that viral protein is a copy of the spike antigen. The spike is the antigen that the virus uses to attach to our cells, our lung cells and many others to get into it and cause the infection. So, if we can create a replica of that inside a persons body, that would be a foreign protein now in a person that their immune system would see as foreign, they would respond in two ways. One, they would generate antibodies, the molecule that binds to viruses and can bind and inactivate them and prevent them from entering cells, and one of the really important features of this approach is its really important at generating t cell responses in humans. T cell responses are kind of the navy seals of the immune system. They patrol the body and clear sites that are infected, so they find viruses hiding within cells, replicating within cells, and destroy those cells which are now corrupted, and by doing that, they then can help clear infection. Dr weiner, your work is always important, doctor, but with this virus and the response to it, do you feel more of a sense of urgency, of intensity, than ever before . I think all of us involved and all of us at home feel the urgency. I think our families feel the urgency. Our families whole lives are changed, our friends lives are changed, and, as you know, there are multiple vaccine types being moved forward. It will likely take several different important successes, not one vaccine, but likely several to meet the different populations that will need it. Its likely to take several different to have more rapid global distribution. I think by working together like this, we will get through this. So, what do you think when you see headlines about the race for a vaccine . I think were very used to thinking things as a race that way, a race this way, but one problem with one winner in this case is that one platform would be the only platform that would be available for a while for production, and so that would mean while you have x, you wouldnt have y, and not having y would mean many people are waiting for that y. In addition, vaccines have different properties. There are some vaccines we manufacture for older populations, there are some vaccines we manufacture the children, and so those can have different properties. To cover everyone we might want to have on the spectrum. I hear what youre saying. The more winners, the better in this particular circumstance. I do have to ask you, though, isnt there as an academic something of a sense of competition, something of a streak of determination to get your particular vaccine out there as one of the frontrunners . I think were going to follow the science on every one of these, and were very dedicated to advancing our platform as fast and as safe as possible. We have. I think everyone is dedicated to getting out platforms that can help, that can be tested in different populations and that can be put together as a global effort to get us out of our houses. Doing what you do, dr weiner, isnt it hard to switch off at the end of the day . This is such intense work, and youre now under something of a spotlight. This is a very intense project, and all of us are really working 2a 7. We could probably go to sleep thinking about it, we wake up thinking about it, so it is an all engrossing project that is very different than the way things were before. Dr david weiner, ending this weeks edition of personal stories from scientists pursuing their research in the face of this deadly pandemic. Im Philippa Thomas. Thank you forjoining us for coronavirus your stories. Hello. Yesterday was the hottest august day since 2003. Temperatures reach 36. 4 celsius in london and some parts of southern england didnt drop below 20 celsius overnight. Lots of sunshine around for many this afternoon, but not for all. There is much more cloud around, across the north east coast of england and that may start to fringe parts of lincolnshire through the afternoon. Also, coastal areas of cornwall could just hang onto more cloud throughout the day. This area of High Pressure building to the north of the uk, it is generating more of a north, north westerly wind, so a north south split in terms of temperatures. The south is where we will see the heat, cool and fresh further north, also keeping an eye on this area of cloud in the north sea, as i mentioned, just fringing North Eastern and eastern coasts of england, cornwall as well, is likely to hang on to some more cloud, particularly the further south and west you are. Fairly light breeze but that wind direction will keep it cooler for eastern coasts. This is where the heat is through this afternoon and areas in and around london perhaps getting up to 3a, 35 celsius. More like the high teens to low 20s for northern england, scotland and Northern Ireland. Overnight, this area of cloud in the north sea starts to extend its way a little bit further west, theres a murkiness, a few showers developing across parts of north wales, through the midlands and into northern england. Elsewhere, there will be some clearer skies, cool and fresh across scotland, Northern Ireland and northern england, once again across england and wales, temperatures in the mid to high teens, perhaps not falling below 20 celsius again for some southern counties of england. Tomorrow, mist and low cloud for large swathes of north wales, through the midlands and into northern england, which will thin and break as the day goes on. It may give a few showers for a time. Again, a mainly dry day, good spells of sunshine, once again, its very warm, if not hot across much of england and wales, temperatures and high teens to low 20s celsius further north. We need to keep an eye on what is happening into next week, we are going to hold on to the heat for many, especially across england and wales as we start to see low pressure becoming more of an influence, its also a good chance were going to see thunderstorms developing and they could well develop quite widely. They are going to be a bit hit and miss, we need to keep an eye on the detail, but an increasing chance of seeing these thunderstorms through next week, they could bring a lot of rain in a short amount of time but for many, its going to stay very warm and humid, notjust by day, but also overnight.
