shona mccallin has been to meet her to find out more. training hard in the gym, building strength, and getting a sweat on, but what if you are on your period? fin a sweat on, but what if you are on your period?— a sweat on, but what if you are on your period? on one occasion i was at the _ on your period? on one occasion i was at the junior _ on your period? on one occasion i was at the junior european - i was at thejunior european championships and i remember just 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 they could have, didn't absorb that amazing like gold medal moment. , ,, , .,, moment. jessica ennis-hill was at the tap _ moment. jessica ennis-hill was at the trip of — moment. jessica ennis-hill was at the top of her _ moment. jessica ennis-hill was at the top of her spores, - at the top of her spores, olympic and world champion in the heptathlon, she had videos, dietitians, and coaches looking at all aspects of her training programme, but nobody looked at when she was menstruating. i when she was menstruating. i always remember it in an awkward conversation, so i had awkward conversation, so i had a male coach and it was predominantly male environments, and i remember, yeah, just having those small

conversations of, you know, i'm on my period or i'm a bit tired or i'm not feeling 100%, but never feeling fully confident about having that more open conversation about how i felt and how it was making me feel when i've trained. but and how it was making me feel when i've trained.— when i've trained. but it's not 'ust when i've trained. but it's not just athletes _ when i've trained. but it's not just athletes that _ when i've trained. but it's not just athletes that this - just athletes that this affects, women make choices about training around the periods all the time. sometimes you want to rest and other times you want to run. that's because we have different hormone levels at different times of the month. our menstruation cycle is split into four different phases, they are period, follicular, btl, and premenstrual. each phaseis btl, and premenstrual. each phase is determined by the two main hormones, oestrogen and progesterone, which are at differing levels depending where any cycle you are. using

this information as a guide, just decided the best way to get her message across to women who wanted to keep fit was an app. after a couple of months of inputting your period data, the algorithm begins to recognise what phase of the muscle cycle you are arena gives you tailored fitness items from yoga to hanes intensity workouts. so items from yoga to hanes intensity workouts. so you do rou:hl intensity workouts. so you do roughly a _ intensity workouts. so you do roughly a minute _ intensity workouts. so you do roughly a minute of— intensity workouts. so you do roughly a minute of that - intensity workouts. so you do roughly a minute of that then | roughly a minute of that then we could go into some core, so positioning assault on the mat. so does your period affect your ability to exercise? well, the team atjennis thinks so and it is something that users are keen to know more about. $5 a keen to know more about. as a lts-lreor-old — keen to know more about. as a 45-year-old woman, _ keen to know more about. as a 45-year-old woman, a - keen to know more about. as a 45-year-old woman, a new. keen to know more about. is —. 45—year—old woman, a new very little about the way my bodywork and i'd decided to learn about that. it still seems to be a djabou to talk about periods and menopause and things like that and i think that's changing under want to be part of that.— be part of that. perhaps we don't know _ be part of that. perhaps we don't know as _ be part of that. perhaps we don't know as much - be part of that. perhaps we don't know as much about. be part of that. perhaps we i don't know as much about our bodies as we should, but the

area is still extremely underresearched and the academic studies which have been done may not be reliable. 42% of the research was actually low quality, so what we do have, the majority of it, this kind of low quality in terms of they won't really looking at the muscle cycle hormones in terms of blood sampling and the methods, so not only do we have a research gap we have this quality issue as well. moving forward, not only do we need to increase the quantity of research were getting we need to make it better so we can get to more accurate conclusions on female physiology. accurate conclusions on female physiology-— physiology. there are a lot of more popular _ physiology. there are a lot of more popular app _ physiology. there are a lot of more popular app available, | more popular app available, including fitting —— vettel women, flow, and women have more tech at their disposal thanjennis ever had. do you think you would have been a better athlete if you train in accordance with your period? it's a really good question. i think that i would have been able to train smarter. i think that when you get to a certain level everything, every small

and has opened 3.5 years late and £4 billion over budget. many of the delays to the project were put down to the complexity of integrating three separate signalling systems. to the east and the west of london, drivers operate the trains manually, where more traditional signalling is in operation. the central core however it uses a system of signalling called moving block. normally you have a fixed block, where you have a colour light signal that tells the driver that a train is clear ahead, whereas with us it is saying it is clear ahead so you can run as many trains as you want to. i can run as many trains as you want to-— want to. i went along to the control room _ want to. i went along to the control room in _ want to. i went along to the control room in east - want to. i went along to the j control room in east london want to. i went along to the i control room in east london to see how it looks from the other side. this is where the magic happens. as is often the case, technology also requires a human helping hand. you are currently _ human helping hand. you are currently shown _ human helping hand. you are currently shown as _ human helping hand. you are currently shown as not - human helping hand. you are. currently shown as not ranked, is there an issue with your unit? i will do that now, i am

little less invasively. on this phone i have petnow which is using the dog's nose print to identify the dog, just like you and use a fingerprint to identify a human, dog �*s nose print is very similar. so let's get to know this dog. come here! it turned out it is actually quite hard to get huskies to sit still for any length of time, especially when you are trying to scan their nose. show me your nose! it takes the phone a few seconds to take pictures of the dog's nose and analyse them in the cloud. it also saves the pictures it takes to the phone's camera roll so you can enjoy them later. in the end, with a bit of help from professional husky marcia nicholas, i was able to get a scan. the app is telling me

this is emma, and it is showing that emma has been reported as missing, and says where she was reported as missing, and i can share my location with the owner so they can be reunited. obviously emma is not really a lost dog, but huskies have been locked in the app so we can —— login app so we can see if we can tell them apart. unlike a microchip which can be cut out of a stolen dog, you can't really remove a dog's nose, not without spoiling the dog. and anyone in theory can check a stray dog without any specialist equipment. backed at base i spoke to petnow to find out why they settled on nose print for recognition.- print for recognition. there ma be print for recognition. there may be paws _ print for recognition. there may be paws or— print for recognition. there may be paws or ears - print for recognition. there may be paws or ears or i print for recognition. there | may be paws or ears or iris, but some dogs really hate going there pores or their ears. but there pores or their ears. but the nose is exposed all the time —— showing there pores. and after about its months old,

to high pressure. but as this area of high pressure continues to push towards iceland, it will open the floodgates to this northerly wind, which is coming down from the arctic. so, for saturday, we start dry, on the cool side, there'll be plenty of sunshine around, but into the afternoon, clouds will develop, most across northern and eastern areas and we could see the odd shower here. northern scotland, down parts of eastern england could see the odd shower, too, but further south and west you are, the best of the sunshine and the best temperatures. we could see 19 or 20 degrees in south wales. but quite cool across north sea coasts, especially with that on—shore northerly breeze. now, through saturday night, most of the showers fade away, there could still be a few pushing into northern and eastern scotland, it does remain breezy. elsewhere, the winds will be light and the clearest skies with it all the cool night to come, i think, a range of around 5—8 degrees typically. sunday is looking cooler — we could see why — the blue hue extended its way southwards around this area of high pressure will be pushing towards iceland.

so, it's going to feel quite disappointingly cool in fact across northern and eastern parts of the country throughout sunday. more cloud around generally across the country, and anywhere could catch a shower. they will be sunny spells in between but quite limited, i think a lot of places holding onto the cloud. it's going to be breezy in the north and east, that willjust make it feel even chillier, but lighter winds across the south—west. it's here where we'll see the highest temperatures again, 15, 16 degrees, disappointing for the time of year across northern and eastern scotland and eastern parts of england. into monday, we could see quite a bit of cloud around generally, we got a shallow area of low pressure across the uk, but there'll be barely any wind, so any showers that develop will be pretty slow—moving. sunshine will be quite limited, so that will affect the temperatures again. i think on the cool side, 11 to 1a or 15 degrees in the south. as we move into tuesday and wednesday, it's a similar sort of story with a slack air flow across the uk. i think most of the showers will tend to be across more northern and western areas through tuesday and wednesday, perhaps turning a bit drier and warmer in the south.

hello, you're watching bbc news. i'm rich preston. our top stories: more details have emerged from the school shooting in uvalde texas. students repeatedly called 911 pleading for help, as more than a dozen officers waited in the school's hallways for nearly an hour before entering the classroom. from the benefit of hindsight, where i'm sitting now, of course it was not the right decision, it was the wrong decision. there is no excuse for that. 21 dead and you're gonna smile and laugh?! you got grandkids? protesters gather outside the annual meeting of the national rifle association, in texas, as the convention continues inside. moscow's advance continues, as russian backed separatists claim they've captured a strategic town in northeastern donbas.
