this week, bio printing cells, talking to strangers, and perfecting your posture. welcome to click. hope you are doing 0k. welcome to click. hope you are doing ok. you probably don't want to hear this, but we are now almost coming up on one year of video calls, zoom meetings, and microsoft teams chats. in that respect at least i think the world has adapted quite well. unsurprisingly, a lot of innovators have lept to the chance to invent a whole range of video call accessories. and my good

cells, the building blocks of our bodies, offer exciting potential. typically these cells are extracted from a blood or skin sample in small amounts. but one company is working on producing any type of human cell in industrial quantities.— of human cell in industrial quantities. of human cell in industrial nuantities. ., ., ., quantities. hello, how are you. thank you _ quantities. hello, how are you. thank you for— quantities. hello, how are you. thank you for having _ quantities. hello, how are you. thank you for having us - quantities. hello, how are you. thank you for having us in - quantities. hello, how are you. thank you for having us in your| thank you for having us in your lap. thank you for having us in your [a . , , ., ., thank you for having us in your lap. this is one of our molecular— lap. this is one of our molecular biology - lap. this is one of our| molecular biology labs lap. this is one of our - molecular biology labs and here we create what is called gene cassettes, and we create space that engineer cells, essentially.- that engineer cells, essentiall . . ., essentially. here at three, an interdisciplinary _ essentially. here at three, an interdisciplinary team - essentially. here at three, an interdisciplinary team has - interdisciplinary team has graded a new technology. it enables the precise reprogramming of entire cultures of stem cells into any cell type on a vast scale. founder and neurosurgeon mike cotter is combining coding and biology to create a new

actually are affected by alzheimer's. what this allows you to do is then use, you know, target your research and drug discovery against the actual condition.— drug discovery against the actual condition. having access to millions _ actual condition. having access to millions of _ actual condition. having access to millions of high-quality - to millions of high—quality human cells could help advance other technologies. a team and south korea have developed this bio printer that could help heal diabetic foot ulcers. a photo of the ulcer is uploaded to the machine which matches the size of the one with biomaterials. this helps with the healing of ulcers which could lead to imputation. —— amputation. this could be aided with the manufacture of human cells and industrial scale and could maximise the capabilities of regenerative medicine. hello

the glue. once it is in place you tap the button twice to calibrate, then if you lean forward it will vibrate, reminding you to set up straight. that is all there is to it. the application records how long you have been starting and how long you have been upright. in my first experiment, i turned upright. in my first experiment, iturned it upright. in my first experiment, i turned it off so the just record. that was hard to do because once you are conscious you are wearing it, you tend to sit more operate anyway. but in my first two—hour stint i was upright just 5% of the time. for the other days when i was set up my desk working i had the vibration switched on. as you would expect, if i leaned forward, it would buzz. there were times where this got a bit annoying because there are lots of times where you lean forward, even if you are resting on your elbows with a straight back, or you get up to make a coffee and you are leaning over the cattle. at those times it would be vibrating, telling you are searching. forthat vibrating, telling you are searching. for that reason i did not wear it all day every day but if i knew i was going to do an hour or two stint at

my desk, perhaps editing a video, i would my desk, perhaps editing a video, iwould put my desk, perhaps editing a video, i would put it on. i did get used to it and there were times where i completely forgot i was wearing it. at least once a shard with it on. thankfully it still works. after using it a few times, those stents where i was wearing it, i was managing to get 80— 90% of the time upright. i am lucky i have never had serious neck or back pain. but i wonder if there are health benefits to this. the company makes no health claims on its ads on instagram. but it does make health related comments on its website. so, i spoke to ashleyjames from the uk's charter society of physiotherapy to ask if there is anything wrong with slouching. there is anything wrong with slouching— slouching. absolutely not. there is nothing wrong with slouching in moderation, just as the same there is nothing wrong with sitting up perfectly straight. what we know is there is no right or wrong position

like this are not ok but you can sit really badly back in a chair and it will never vibrate. from my point of view i have enjoyed wearing this, i see in the shops with the mirrors, i see myself stepping over. but now, when the pandemic is over and i get to go to a positive event, i might wear this to remind myself to sit up straight and keep my shoulders back. that was chris. and this is chris. watching it made me want to sit up straight. it does seem it is more about movement than posture? more about movement than osture? . more about movement than posture?— more about movement than osture? . ., , posture? that was certainly the view from _ posture? that was certainly the view from the _ posture? that was certainly the view from the physiotherapist. | view from the physiotherapist. as long as you're not spending all day sitting in one position and moving around a bit more, then that may be comfortable for you. that make sense to be over never been someone who suffers back pain but the time i have had a sore back, a sore coccyx has been when i have

here, too. a slippery sort of day though, i think, for much of scotland with that rain, sleet and snow continuing — and turning to snow, lower levels in scotland throughout the day. we've got wetter weather across northern and eastern parts of england, some heavy bursts of rain — that'll turn to snow over the pennines and the north york moors later on. out to the west, it'll always be drier and brighter. those temperatures will be lower than they were on friday, and it will feel colder in scotland and northern england as that wind starts to pick up. now, it'll get colder as the weekend goes on. the originating all the way from the arctic coming down across the baltic sea, over the north sea into the uk, and engaging with storm darcy — it's been named by the dutch met institute. now, the biggest impacts of that will be felt in the south—east of england and parts of east anglia. this is where attention turns overnight and into sunday, with some heavy falls of snow mainly to the east of london. there'll be some snow widely, though, across the south—east of england and east anglia. there will be drifting and blizzards, as well, because it's going to be very windy here with gusts of over 50m/h.

it'll be a windy day everywhere, though, on sunday — or feel cold, as well. there may well be some sunshine away from south—eastern areas, and there will be further snow showers blown in off the north sea as well. and those temperatures continuing to drop, only getting a few degrees above freezing on sunday, feeling colder still. now, we've got high—pressure to the north of the uk, and lower pressure to the south, hence that run of easterly winds continues through sunday and into the beginning of next week. that means more snow showers getting fed in off the north sea, mainly affecting some central and eastern parts of scotland down the eastern side of england — more snow and ice warnings continue into the early part of next week with temperatures barely getting above freezing. given the strength of the wind, it will feel much, much colder.
