we can use these swabs and this device which tells us the level of microbial activity on the phone in relative light units, or rlus. so the higher number we get, the higher number of germs. the results are pretty good. so we would want a surgical surface to have a rating of 50 or less and all of the phones have readings of less than this, so that's pretty good. so they're significantly cleaner with just soap and water? yep, they are. how is that possible without using antiviral gel? what's going on here? the main ingredient in soap is a detergent, which is basically lifting off the grease and grime and the germs from the surface of the phone, which is then rinsed off with water, and that's what makes it clean. there are a few other ways you can clean your phone safely. this week, apple changed its guidance and that is if you have an iphone, you can safely wipe it with a 70% isopropyl alcohol wipe — the kind you can get from a computer shop or online, if they haven't sold out. there are also devices that can sterilise your phone using ultraviolet uvc radiation. this one is called phonesoap.

it costs about £80, although there are cheaper ones available, and what you do is pop your phone inside and let it cook for about ten minutes. the manufacturer says that shouldn't harm your device but some phones or cases could be discoloured over time. finally, what can you do if, like me, you have stripped the oil—repelling coating off your phone's screen? there are some ways to fix it. first of all, you can get a screen replacement, although that is not going to be the cheapest option. or you could stick on one of those glass screen protectors, which is a quick and easy way to fix the screen. or you can try this. it's called liquidnano and this wipe puts a silica dioxide coating over the display, which says it will restore the oleophobic properties for 12 months. it cost between 20 and £30 and you have to let it set on the phone for at least half an hour. so i tried it out on the phone

i ruined and i have to say it seems to have done a pretty good job! so that's one solution to what could have been an expensive mistake. just remember that if you do clean your phone, as soon as you touch it, you are putting germs back on it again and the most important advice remains to wash your hands thoroughly and frequently. that was chris. now, later this month, a number of globes here at the british library, some of them over 400 years old, are going be made available online in full, 360 interactive form. this isn'tjust a way of immortalising these fragile objects but also making them available to the masses. the digital globes project will eventually see 30 of them brought to virtual life without the risk of any grubby mitts damaging the originals. anthony, here we have the capturing process, quite a few dslrs. can you talk me through the set—up?

it's not actually capturing the whole globe, it's actually capturing elements, and the process is called photogrammetry. so once all the images go through to the computer, the software we'll be using will render all the images together to make one complete globe. once they are all knitted together, you have to make sure that the colour‘s right, is that what that colour chart‘s for? that is correct. for example, we can do a 3d print from the items. so if you can do a 3d print, you need to have it exactly the right colour. so people can recreate their own — not that these globes are entirely accurate. california seems to be an island. and it wasn't due to ignorance in the 1700s, as some earlier maps had it right. inaccuracies were purposefully placed in maps for all sorts of reasons. such as, putting continental rivals, for example, down a wrong route or sending them the wrong direction.

as well as being available on the british library's website, there is also an augmented reality version which is within an app called sketchfab. this is accessible on any ar—compatible device. so here is the map and to turn it into ar, i tap on this and it is going to appear in front of me and then, i can travel around the world. it's an interesting contrast. while this looks so ancient to us, it was technology in its time and now we're mixing that in with a bit of augmented reality — technology of our time. so whilst there may have been a little polishing in the virtual versions, these globes still provide the history lesson of how the world was seen — notjust geographically, but politically — in each of their eras. so earlier, we were talking about the coronavirus. but now, to a very different sort of health risk — the snake bite.

around 5 million people every year are bitten by snakes and, of course, we know how dangerous their venom is. it can cause crippling injuries and be fatal. india is one of the parts of the world that has the highest death toll, falling into the tens of thousands every year. so could something as simple as a mobile phone app actually bring those numbers down? david reed has been gujarat in the west of india to find out. these guys are off to catch one of the world's most dangerous animals. the cobra. highly venomous. they're using a new life—saving app. it has told them a snake has been spotted in a local gujarati workshop. to bag it and get it back in the wild, they first have to find it in a pile of stuff where every second thing looks like a scary snake.

this is going to take time, so let's check back with them later. first, we're heading to a local hospital to see why this app is so important. this conservationist is going to guide us there with his indian snakes app. so we are here and have to go here which is about 25 kilometres away. it gives vital details to those bitten by snakes of nearby hospitals stocking the antivenom that could keep them alive. we actually are going to meet this doctor who is a specialist in snake bites. so this is the hospital. the hospital is there, the name is there, the phone number is there. we get there in snake bite rush hour. we've been here only a very, very short time. and in the matter of the last five minutes, three new patients have

come in, complaining of snake bites. to help identify the snake, patients often kill the animal that bit them. this is a highly venomous russell's viper. but administering antivenom carries its own health risks. doctors hold off using it and instead do a battery of tests until they know it is not a dry bite and the patient is showing the effects of venom. he will be under observation for 48 hours. if any venomous symptoms we see, then we will start the antivenom injection. often, there is no time for wait and see. a number of bite victims waste precious time visiting faith healers over hospitals — it's one of the reason so many die from bites each year in india — estimates say as many as 50 to 60,000 people. the indian snakes app aims to get people to hospital fast.

the first moments, the first minutes, first hour of a snake bite, is very, very important. the major problem that we face is people don't go to the hospital first, they go to the local, traditional healer who they trust. and then, when is not possible for him, he will send the patient to the hospital. the first warning on the dos and don'ts list is don't go to a faith healer. the second, don't suck out the venom, whatever you've seen in the movies. there's also a field guide to id venomous snakes. you want to see the snake in detail, so you can click on the picture, you zoom in... you can also report a snake in your house and call a rescuer. click on this. this is your current location, you'll find your nearest rescuer. all you need to do is contact the rescuer. remember these guys? let's see how they're getting on. actually, pretty well. they distinguish the snake from yards of cabling. it then instinctively made a dash straight into their black bag.

and with a little coaxing, popped safely inside. the indian snakes app is notjust about saving lives and helping snake rescuers, but also conserving and learning about snakes, especially in their conflicts with people. we get a lot of data from out of the country about the demographics, and epidemiology of snake bites. so it's kind of getting knowledge and giving knowledge app. do you think snakes are kind of understood? completely, they are one of the most misunderstood group of animals. so this app's main purpose is to sensitise people of india to start working on snake bites and snake conservation, and lead the coexistence of the snake's life in the future. better education about how to avoid and treat snake bites could well transform our attitudes to one of the most feared and demonised animals on the planet. dave reed there in india.

that is it for this week's show. you can keep track of the team throughout the week on instagram, facebook, youtube and twitter at @bbcclick. thanks for watching. hello there, we had some pretty big contrasts weatherwise across the uk on thursday. it was the north of the country that had the best of the sunshine. this is how things looked in the highlands of scotland, and across england and wales we had this weather front that has been with us for a number of days, bringing grey and gloomy weather. some mist and drizzle around here in hampshire and across the south wales sunny bridge, temperatures only got to five celsius, pretty chilly. over the next few hours,

that weather front stays with us so expect it to stay dull, damp, some mist and hillfog patches around through the night but it is the cloud that stops that temperature from falling too far, so those around five or six celsius across the southern areas of england. further northwards, with clear skies and light winds, it is a cold night, the frost more widespread. the lowest temperatures in scotland —6 or —7 celsius. friday then, and this area of high pressure is going to strengthen, this area of low pressure is going to deepen. the winds are going to blow more strongly across england and wales, a cold wind for many of us developing, but particularly so across the headlands of south—west england, with gusts of a0 miles an hour. brisk winds for the coast and hills of wales, a noticeable chill in the air for the midlands. could be an odd shower working into northeast england just for a time. not many of these, for most of the northern half of the uk, looking at great weather with plenty of sunshine. for the weekend, our area of high pressure is still influencing our weather.

notice we have some fairly tightly packed isobars so it is going to be quite a windy start to the weekend on saturday, noticeably so across eastern areas of england and eastern areas of scotland, around the coast feeling quite chilly. looking quite cloudy through the day in northern ireland, but there may also be some areas of cloud coming in off the north sea to affect parts of eastern england and eastern scotland from time to time. these temperatures are nothing to write home about, highs of 8—11 celsius, a little bit cool for the time of year. similar weather conditions on sunday, there will be a lot of dry weather and some sunshine to go around, but again, the cloud received from place place will vary. and it could be that we see some thicker cloud edging into the northern and western isles, maybe even thick enough to bring a spot of rain. for most, it is another dry day, so a dry weekend for most of us to look forward to. beyond that, the high—pressure still in the weather, tuesday maybe some thicker cloud for northern ireland and scotland threatening some light rain. and that's your weather.
