said thousands of civilians are living in shelters without access to electricity or water, as the fierce street fighting continues. now on bbc news, click: female tech innovators. the bbc has just revealed its 2022 list of 100 inspiring and influential women from around the world. so this week, we're celebrating the achievements of female tech innovators. shiona meets an absolute legend of the sporting world to find out how tech is transforming her game. hello, hi.

i go to the world's biggest start—up campus in paris, where female innovators are cooking up some amazing ideas. it tastes a lot like egg. there is a bit of an aftertaste, a slightly bitter aftertaste. mmm, bit of seasoning maybe, or mouthwash? anyway, i've been to meet a female tech boss who is helping to shape the future of surgery. the contribution of women in all walks of life has often been forgotten, because history has mainly been recorded by men. but here at the glasgow women's library their achievements are rightly celebrated. this is the only accredited museum in the uk dedicated to women's history, and it is filled with books that are about, for or by women. 20,000 books and 500,000 archived items here are providing a valuable resource

for researchers and historians. amongst all of that, you will find stories about some amazing women. like this one. i'm a bit of a fan of ada lovelace. when i learned to program computers when i was young, i could practice on the computers that i had around at the time. but when ada lovelace wrote the very first algorithm in the 1840s, computers didn't even exist. her code was designed to run on a theoretical machine that only existed on paper. there are other great women being celebrated here too, who you might not immediately associate with technology. shiona mccallum has been catching up with a female sporting icon to talk about some new tech that's helping players and coaches collaborate on court. in tennis, every little thing counts. and that can really be felt here, at the billiejean king cup finals in glasgow.

with more than 100 countries involved, it is the largest annual international team competition in women's sport. this year it was won by switzerland. they were amongst the teams embracing billiejean�*s collaboration with microsoft to add another layer to their in—match coaching during games. analytics of all aspects of the game are being generated from ball tracking cameras and 3d radar systems around the court. the data can then be accessed via cloud platform azure, meaning professionals and their coaches can see it in real—time during their play. so can this technology really improve your game? well, i'm going to go and test it out, and i'll do this by playing one of my long—standing rivals... i'm ready for this, yeah. ..my dad.

my backhand is my best shot, so i'm excited to see what the data says. although i am far from being a professional. oh, yes, what a shot! i have noticed that you do favour your backhand a bit, and you are quite strong in your backhand. 0n the return of serve, you're still dropping it a little bit short, but as soon as you've gone into that third ball, look at that shot — you have a tendency to really push it deep, push it wide. it does result in some points won for you right there. if you're a player, among the things you always want to know are: where should i be serving, and what speeds do i need to hit to be able to serve an ace? you also want to know what side your opponent is stronger on, where they serve on certain big points, and how they position themselves on the court. it's thought by looking

at all these stats and really drilling into the information provided, tactics and strategies, movement, shots and ball speeds can all be fine—tuned, and you can get as close to winning as possible. and someone who certainly knows a thing or two about winning is billiejean king. with 39 grand slam titles, she is a legend of the game. how much of a better player do you think you may been if you'd had access to this? so much better. i was very adaptable and i could learn quickly if someone showed me something, and i loved challenges. so adaptable, you can set it up anywhere you want. you can find out about your rpms, how much spin on the ball, you can find out trajectory, you can find out percentage of first and second serves. what do you say to critics that might say, well, they want to keep tennis a bit more traditional, and this is almost cheating? not happening. i think it will hurt our sport if we went that way. whether the big tournaments

will arrive at the same conclusion and adapt the tech remains to be seen. but in theory, these cameras could be used outside of tournaments, too. what champions do is they practice their strengths every day. everyone talks about mistakes all the time, but you first want to know what your strength is. so there is a combination of things you can learn with the microsoft tablet. you want to look at, what do i do really well? like your dad was getting the serve down the middle really well. but that verifies it so you go, i'm on the right track. you have to know your strengths in life — it really relates to life as well. when you look there and you see these stats — i wish, oh my god, i would have given anything to have what you guys have. because i like all this, i love information, i love learning, i love all these things, and our generation, we couldn't even look at videos. and she's not the only one thinking that using this kind of tech can be beneficial. coco gauff made headlines when she became the youngest

player since 2005 to qualify for a wta finals. you've seen people lose matches in millimetres, and lose matches because they got aced in the same direction over and over again. i've certainly lost matches where i did not notice that i was getting served to the same spot because you are so caught up in your emotions at times. so definitely, when you can see it, and you know when your coaches say it as well, some time you get stubborn out there so you don't believe it — but when you can see it for yourself, i think it is a different addition to it. these analytics, which are now available to the players, cannot only enhance the competition but can also give something to the fans. everybody in the stands should probably be seeing all this, that's what i'd like to see. children today and young people want experiences. what affords you experiences? technology. do you really see this as the future of tennis?

oh, for sure, it is here already. it's just going to get better and better. roisin has come to the west end of london to watch some live theatre — no, not that kind of theatre, this kind of theatre. this cloud—based platform now allows trainee surgeons to scrub in virtually, from home, on the bus or, in this case, on the street. could you walk me through what's going on? speaks indistnctly. sometimes it is quite hard to either get the time to get into theatre, or it can be quite busy. so being able to watch things in my own time or remotely is really helpful, it also helps getting more i—to—i interaction with the consultants so i can

speak to them via the proximie app. roisin is watching a feed coming from an operating room at st thomas�*s hospital in central london where a patient is undergoing robot—assisted surgery to remove a section of their colon that's been affected by cancer. more than 2,000 surgeries have now been conducted at the hospital using the platform, which has been developed by a company called proximie. there are four cameras in this operating room. two are giving an overview of the entire procedure from different angles. vicki is wearing the third on her headset, and the fourth is on one of the robot arms, which is currently being used to see inside the patient. all four of these streams are recorded and stored in an online library that other surgeons and trainees around the world can access. even today's surgeon, who is extremely experienced, has found it useful. for us, it has got a couple of uses. when i was starting

on the robot, it means we can look back at our own videos and it helps with our own learning and training and see what we were doing, how we can do it better, and make us more efficient. also if we have any complications, it is recorded — we can look back and see, could we have done something different, could we have avoided it or could we have managed it slightly better at the time? today, you are going to have at least one student watching live, and she's going to be able talk to you. doesn't that get annoying, doesn't it distract you in important moments? no, previously students would be in the room and they could not really see much. now they are in a separate room, watching in comfort. it is not distracting at all. we're used to people asking us questions. like me. yeah. now, the traditional medical adage is "see one, do one, teach one" — but i wonder whether it might be evolving into "stream one, see one, do one, teach one". and this evolution has come at a vital time for trainees in particular. obviously, the pandemic

affected everyone but surgical training was quite hard hit. lots of cases were cancelled so having somewhere i could keep up—to—date, keep in touch, remind myself about things is really helpful. but while it's a useful training tool, the platform's primary aim is to get the best surgeons into as many theatres as possible. knowing today that 5 billion people around the world lack access to safe surgery — that's not localised to a particular part of the world, that's everywhere. but we also know that even within developed countries, there are challenges around accessibility, variability and the workforce shortages we have. the platform is basically ensuring patients have access to the best care, no matter where they are. so if it is a local hospital or more of a suburban area that doesn't have the expertise on site, historically the patients would have to travel many miles and days to get to that care orjust not have access to it. now it brings expert care closer to patients, to their clinical teams and where they need it.

it's really improving access for patients but also for clinical teams to upscale and support their local population where they need it. from the uk to the us, from kenya to peru, the proximie platform is now being used in hundreds of hospitals across more than 50 countries. in the last year alone, it's assisted with over 17,000 surgeries. it has taken a lot to get this technology off the ground, but not all of the hurdles were technical ones. what has been your experience as a woman in healthcare and technology? have you felt it's been harder for you than it would be if you were a man? i think there is no doubt it's harderfor women in these environments. trying to raise money, trying to build a company that is going to fundamentally disrupt surgery. i remember people telling me when i went to a fundraiser early on, someone told me, "this problem is too big for a female surgeon to fix", quite blatantly. and so, i am glad we are

hopefully being able to prove them wrong so far. how do we fix it? how do we fix it. when we talk to recruiters we are pretty particular. if you're not going to show us a diverse candidate list, gender and ethnicity, we are not going to work with you. you really have to instil the minimum requirements. you want to make sure you're making a concerted effort to hire within those minority groups. back at st thomas�*s hospital, the operation is nearly over. this is where we're at with surgery, where the surgeon can pilot a robot which actually is in the patient. it's properly humbling what's going on here, when you think about it. the surgeon over there is piloting a robot over there that is removing someone�*s cancer. 0k, time for a look at this week's tech news now.

social media giant meta has threatened to remove news content from facebook in the us. the company has spoken out about a us law that would give news organisations more power to negotiate fees for content shared on facebook. it's warning comes after a similar australian law saw a brief shutdown of facebook newsfeeds in the country last year. as speculation over twitter�*s future under new exec elon musk continues, one of his former colleagues at rocket pioneer spacex says the road to twitter 2.0 could be tougherfor mr musk than he expected. i would, by rule, never bet against him, but i think this is going to be harder than he has anticipated and i think it will be a lot of work for him, and i hope it doesn't become a distraction from the other things that he is doing that i think are incredibly important. disney research studios says its neural network fran has been trained on thousands

of computer—generated images of different faces at different ages to provide a fast, production—ready way to tweak the age of actors on screen — i think i need that. and finally, apple is rolling out its self—repair service in the uk and seven other european countries. iphonei2, 13 and some macbook users will now be able to fix their devices by buying parts and tools and watching online tutorials. accordion music plays. paris. the romance. the culture. the food! the iconic sites. brakes squeal. the biggest start—up campus in the world. this is station f, cemented in a city with a now buzzing tech scene.

this place plays host to 1,000 start—ups and in this room alone, there are 3,500 desks and 30 incubators. it really is a place for ideas to thrive. landing yourself a space here doesn't come easily. it involves a stringent selection process where founders are generally expected to be working on the product full—time, have a prototype or something to show, and already have some users. there's even a green tech meetup happening here in the midst of the open offices of investors and big tech companies. so for apps that want to find their place on the app store, well, google is over there, apple's over there, so there's help close at hand. and five years in, a1% of the founders based here are female — a very different proportion to that of the wider international tech scene. every single partner programme

we have at station f needs to do its best effort to get females in the applicant pool. not necessarily selecting people because they are female — we actually discourage quotas like that at station f — but we believe that once you have more women as candidates, the conversion rate will be higher. dora founded blazer, a parisian start—up using data to analyse early response to cancer treatment. being a founder of a start—up in med tech in an environment that is going to have more ceos that are men can be a bit daunting for some founders, and the fact that station f has created this programme, i think demystifies it a little bit. and this place has hatched all sorts of companies. i've come around the back to a hidden kitchen where i am going to taste some vegan egg replacement. yeah, it is le papondu. it's a project that can replace egg from a beaten egg,

for example to cook it like an omelette, scrambled egg, but also different recipes. lovely. it looks like hollandaise sauce at the moment. the last time i tried a egg replacement, it really tasted of coconut, so i am looking forward to seeing what this tastes of. sheryline and her co—founder were biotech students when they won their place on the female fellowship programme here. as two scientists, they really wanted the entrepreneurial guidance to combine with their knowledge of how to cook up something interesting. our main ingredient is fava bean flour, but also you have canola oil, water, salt, carrot extract. wow, carrot? it doesn't look very carroty. how is this different to the other egg replacements that exist? it's very important to have good nutrition facts, we have only seven ingredients. it is less calories than egg but also rich in protein. thank you very much.

it tastes a lot like egg. there is a bit of an aftertaste, a slightly bitter aftertaste. but it is a good replacement. the texture is right, and i am eating it by itself so as soon as you have mixed it into a recipe or anything i'm not sure you would notice it. i am trying another mouthful. which is a good sign. 0utside these walls, though, there are still many challenges. it is great to be a female founder at station f. when we go out of this environment and we face the real world, we do have still some disparity in terms of funding and the numbers of 2—7% of funding being given or allocated to female founders are real, and we need to do efforts to change that. other places are, of course, taking on the gender imbalance, too. today, there are so many resources, so many opportunities, so many discussions. people are really engaged and they want to see a difference. and this was not the case from about ten years ago,

where people weren't actually even conscious that there was a gender issue in tech and it wasn't anywhere in the conversation. we have to see maybe more diversity within venture capital teams, we have to see them actually — maybe in the same way as we have done at station f — really go out and increase their applicant pool and then at the different start—ups that they are considering forfunding but i think there is a lot that needs to be done to really get us to where we need to be. whether it's fitness apps that sync with periods or solar shirts that are better for the environment, women are creating tech that's making a difference. and here are some of this year's highlights. first up, click met 0lympic medallistjessica ennis—hill to find out about her fitness appjennis, helping women train around their cycle. 0ne occasion, i was at the junior european championships and i remember running that 800

metres, thinking, "i'm trying to run for a gold medal here, but i'm also very aware that i've just started my period". ijust rushed off the track and felt that i couldn't have — i didn't absorb that amazing, like, gold medal moment. the way the app works is that you can input your period data to find out what phase of the cycle you are in. it then gives you tailored fitness options to suit your energy levels at any given time of the month. i think that maybe if i would've spent more time understanding particularly when to push myself in the strength room for example, in that follicular phase, then perhaps i would have built more lean muscle and become stronger, and, who knows, that may have affected my performance in a positive way. we went to the netherlands to visit pauline van dongen. she creates textiles with solar cells woven into them. her idea is that these fabrics are a more tactile way

for people to interact with the sun and its energy. what i really like with this sample is that it gives you such an immediate visual feedback when you put your hands on it. this was pioneering at the time because smartphones were rising, everyone was struggling with charging their phones — especially when they're out and about — and this t—shirt could actually solve that issue. but solar textiles can be about much more thanjust fashion. the solar technology we are using is the type of solar cell that has the lowest carbon footprint. ten years ago, intelligent textiles were maybe a nice to have, but today with all the challenges in terms of sustainability and emotional well—being, textiles are really the solution we need. and finally, car safety testing is still largely done on the same dummies that were used in the 1980s, which were based on the male form. we went to visit a team of engineers in sweden who are in the final stages of developing the first average

female crash test dummy. females are somewhat shorter and lighter than males on average and then, we also have differences in muscle strength, which plays a role in terms of how you respond to a crash. siren wails. so, we've just seen the crash test, what are we now seeing on the screen? you see the relative motion of the torso and the head and the head interacting a bit with the head restraint. there will probably not be a scratch on your car if you are hit in this severity. no damage and so on, but you see the amount of motion that goes on in our body when we are impacted in this severity.

it's taken us decades to get here, but a crash test dummy representing the average female is close to becoming a reality, bringing with it hopes that women will one day be safer behind the wheel. well, those are our highlights from 2022. the bbc has just published its annual list of 100 inspiring and influential women, and you can find that online. and that's all we've got time for. we shall be back next week. thanks for watching! bye. hello, there. it's been a rather grey and gloomy saturday for many. a few scattered showers around as well. take a look at this

weather watcher picture from thurnby in leicester, fairly indicative of the day. now, if you take a look at the satellite picture, you can see how extensive the cloud has been. there were some breaks across north—east england and parts of scotland, but also some showers. and drawing your attention to this speckled cloud in the far north—east, potential for some snow showers waiting in the wings to arrive later on monday. so, through the next few hours, we keep that blanket of cloud for many, some coastal showers out to the west and east, perhaps more persistent ones in the far north—east of scotland. but because of the cloud around, on the whole, temperatures should just stay up into low single figures, but it's going to be a chilly start to our sunday morning. once again, another grey and gloomy day, almost a repeat performance of saturday's story. there will be some coastal showers around, on the whole, largely quiet and temperatures sitting between 6—9 celsius, just that little bit colder in the northern isles as that cold air starts to descend. so, arctic air pushing its way

steadily southwards as we go into monday. so, really from monday onwards, you're going to start to notice the difference to the feel of our weather. if you haven't already heard, it's going to turn cold and windy, and snow and ice could be an issue, particularly to the far north and east. so, it's likely as we go through the day on monday, this weather front will introduce the colder air. it's going to turn the rain ahead of the front into snow showers behind it, particularly across the far north and east of scotland and north—east england. to the south of that weather front we'll still keep those temperatures around generally 7—9 celsius. but then that sinks its way steadily south, so we start off on tuesday with some sunny spells, cold and frosty. and, yes, there will be further snow showers across northern and eastern coasts, and those temperatures are going to struggle, 11—5 celsius, but factor in the strength and the direction of the wind, it certainly will feel noticeably colder. so, certainly you'll need to wrap up warm.

it looks likely that we are going to see that cold snap continuing through the middle part of the week as well. so, if you've got outdoor travel plans monday into tuesday, do be aware that there's a potential for snow and ice in the north—east.

this is bbc world news. i'm vishala sri—pathma. our top stories... a un summit reaches a legally binding agreement, on an environmental treaty for protecting high seas bio—diversity. we will formally adopt the text in all six official languages of the united nations. a reduced growth rate, increased defence spending, and army training in combat conditions — some of the things china announces at the start of its annual parliamentary session. in israel, up to 200,000 people take part in protests against the government's planned judicial reforms.
