the headlines: president trump has said there is no place for political violence in the united states, after several low—grade explosive devices were sent to barack obama and hillary clinton. several other democratic party politicians and officials also received them, as well as the broadcaster cnn. there's "serious and growing concerns" about the human rights situation in xinjiang where the bbc has uncovered fresh evidence of china's campaign to detain and re—educate muslim uighurs. our correspondent has been hearing the stories of some of those who have fled the region. saudi arabia's de facto leader crown prince mohammed bin salman has described the death of the journalist jamal kashoggi as a "repulsive crime that cannot be justified." in his first public comments on the killing, he told an investment conference in riyadh thatjustice would prevail and all culprits would be punished. a so—called celebrity hunter has provoked anger after posting pictures of dead wild goats and sheep she'd just shot on the scottish island

of islay. the local msp, who is also a government minister, described it as "horrific" and has called for the practice offered by several tourist companies to be stopped immediately. the scottish government says it expects shooting to be carried out humanely. a warning that some viewers may find rebecca curran‘s report upsetting. welcome to my office. larysa switlyk describes herself as a hardcore huntress, seen here hosting her programme, she recently took a trip to scotland. and it is these images posted online by larysa switlyk that are causing quite a stir. they show her posing with a goat she a p pa re ntly her posing with a goat she apparently killed on islay. others show her in camouflage with a rival and another with a dead ram. show her in camouflage with a rival and another with a dead rami show her in camouflage with a rival and another with a dead ram. i think

that for every person that will find this an attractive image and bring them to islay, there will be a thousand or more who will be repelled or horrified. it is unacceptable, it shouldn't be happening, i have raised the issue with the environment minister and i know that people are, by and large, outraged by it. celebrities have also condemned the pictures. feral goats are non—native species in scotland, and the state is obliged to control the numbers. hunting them isn't illegal on private land. to control the numbers. hunting them isn't illegal on private landm contributes £150 million a year in tourism. £69 million is spent on shooting and stalking as the bulk of that money comes in the autumn and particularly the winter months, so rural economies are struggling with other forms of tourism and are benefiting from relatively wealthy tourists coming at times of year. benefiting from relatively wealthy tourists coming at times of yeahm is easy to see why tourists flock to islay, but for some it is not for the stunning scenery. several companies offer the chance to store can shoot wild goats on the island,

dumfries and galloway, and other parts of the uk. larysa switlyk didn't respond to our request for comment today. rebecca curran reporting there. now on bbc news, it's time for click. this week: bouncing bots... leaping lights... and hand—springing humans? woman on radio: all systems are ready. ignition. japan has just done something amazing. it has flown a spaceship to a one—kilometre—wide near—earth asteroid called ryugu to do some incredible science. this is hayabusa2.

it has just deployed three rovers onto ryugu's surface — the german and french mascot probe on 3 october, and before that, the japanese minerva ii robot. their mission: to measure temperature and magnetic properties, and take photos of the surface. and amazingly, this is how they get about. yep, they bounce. i have come to the japanese aerospace exploration agency, jaxa, to meet the team who designed the mission and get my head around this bonkers mode of transport.

in summary, this hops off the surface of an asteroid, it jumps about 10—15 metres into space, it stays... off the surface for about 15 minutes, and then comes back down... bounce and bounce and bounce. the images already returned by the minerva ii bots are wowing the world, but the risks they face are high. what are the biggest risks with these rovers? ah, everywhere. laughs. actually, so we did not have much budget, so we did not use very expensive devices. the rover hops and then bounce and bounce, so in that moment, the mechanicalfailure would happen, so something was broken. and, so another issue is the temperature.

the asteroid is rotating, so the temperature gets down to below —100 degrees, i don't know exactly, but that is also a big problem for the devices. so this is a replica of hayabusa2. and believe it or not, deploying the landers is not even the coolest thing that this is going to do, in my opinion — because this is going to land on the asteroid, take a soil sample, and then take off again. which i think is absolutely incredible. the first attempted landing is hopefully going to happen very soon — by the end of october. and then a little later, a second landing will collect more soil. we think that there are organic matters on the surface of asteroid.

so if we can get the organic matter, we can study what kind of organic matter were exist, when the earth was born. now... that is a model of hayabusa2 there. it looks very delicate to me, and you are going to try and land that on an asteroid. what are the risks, and what is the most risky part? the most risky part is the surface of ryugu is not smooth. we imagine that, we can see the surface battery, maybe it is covered by sand, but in fact the photo that minerva sent us, there are lots of boulders. big and small. we cannot find a wide area with no boulders. so that is our main issue. assuming all does go well,

next year hayabusa2 is going to go one better and try to collect soil from under the surface. and it is going to do that by using an explosive to blow a hole in the asteroid! and then, in one final heroic act of science, it is going to fly back to earth and return the soil samples to jaxa scientists, possibly to help them unlock the secrets of life itself. we don't know where the life was born. it may be on the earth, or it may be in the universe. we don't know that. so we want to study the original organic matter that exist when the solar system was born. thank you very much for your time. very best of luck. thank you very much. he is going to lend a space ship

on an asteroid and then take off and fly back to earth! now, every year in october, the tech world turns its attention to ceatec, japan's big tech show, which is a fascinating glimpse into the direction this country is taking its innovation. emily bates and dan simmons are on the show floor, and here is the first part of their ceatec tour. this is notjust another tech expo. it is quirky. yes, that is a sort of green pea alexa. and how about replacing alarm clocks with blowing air from the ceiling to wake us up? even though you don't like to be woken up. it is like somebody quietly going... laughs. so it is just a question of us finding what we think could be

the next big thing. you know what it is like. you are stuck behind a car and you can't overtake, because, you just can't see beyond that vehicle. well this car might be able to help you. it is fitted with a demonstration of a new technology called xtravue, and it means that you can see through the car ahead using its camera rather than yours. the vision of its makers valeo is that the live stream from cameras in our cars will be available to everyone within a certain area. the forthcoming 5g cell network will make this tech more workable. imagine not having to guess what it could possibly be that's holding you up. horn honks. lucky escape! here is another angle on cars from mitsubishi. as the viewer changes position, so the car and lighting effects shift with them. obviously the car would not move

like this in real life. what it would do is that as you move around it, the lighting and reflections would change, and that is what this is trying to demonstrate. the hope in the future is that it can be used on billboards so that the objects within them glint and shine as you pass by, as if they were really there. but you had better hope it is a quiet street because at the moment it only works with one person. does it look as though the headlights are following you around the room? look up and see how natural these skylights look. up until now, if you wanted a fake window, the fitting would contain either a blue light or blue glass or perspex. there is actually no blue light behind here, it is just two white leds either side, with suspended diffusers, mitsubishi describes them as, in between, to replicate the way that natural light comes through the atmosphere.

they won't give us any more information, and they say it is about 2—five years away before something like this could be installed in our homes, hospitals, or maybe even the underground, to give us a little bit of extra natural light. it is almost like i am expecting to see outside! while dan is busy seeing the light, i found myself talking to trees. now, something you might not expect to see at tech show is a bonsai tree, or should i say, a bons—ai. the tree, or maybe it is just a fancy pot, will automatically move towards light, let you know if it needs water, and even offer wise words of advice to its owners. robot: "i find out what the world needs, and then i go ahead and invent it. " at least that's what thomas edison said. only injapan. this could be one of the standout technologies of ceatec this year. the ability to detect cancer through a urine sample. and hitachi is saying they can detect cancer in its early stages and tell you what kind it is.

it works for breast cancer, for lung cancer, bowel cancer and some childhood cancers, paediatric cancers. initial tests look very positive, they only have a small sample at the moment so more testing needs to be done. how long will it take to get into surgeries will be the question everyone is asking. such an important development. injapan we are thinking 1—2 years to get through the formal stages of acceptance by the government. in other countries like the united states, if hitachi decided to do some testing there, this could be available to the public within the next 3—4 months. certainly by the summer of next year. advances in mass spectrometry and machine learning have made the biomarkers in urine that change with cancer more easy to detect. and, it is hoped, as reliable as a blood test.

obviously it needs a whole lab setup to do the testing at the moment — but the future, maybe five, ten years down the road, hitachi are already talking to a toilet manufacturer to put the testing element of this technology into toilets. so we could get a situation where every time we go for a pee, we could get a result to test and check for any early stages of cancer. hello and welcome to the week in tech. it was a busy week for robots, with boston dynamics' atlas showing off its new parkour skills, pepper the robot addressed the uk parliament on artificial intelligence and education, and binali8 became the first robot to co—teach a class at us military academy westpoint. bima had previously passed a college test in california on the philosophy of love. the co—founder of microsoft paul allen died this week at the age of 65 after a recurrence of cancer. bill gates paid tribute to his former business partner saying microsoft would never have happened without him.

the pair met when gates was in the seventh grade and started the company in 1975. an automated system has been developed to detect dense breast tissue in mammograms and is said to be as reliable as an expert radiologist. researchers at mit and massachusetts general hospital developed the deep learning model, which was used on real patients in a clinical setting. dense breast tissue is an independent risk factor for breast cancer, and the automated system can significantly reduce the amount of time spent on image analysis. mit also announced they'd be putting $1 billion into a new college for artificial intelligence. the school will open next year and pairs students with expertise in fields as diverse as chemistry and history with machine learning courses. and finally, the power of electricity has been harnessed to keep your chewing gum fresh as you chew, by zapping your tongue. it's apparently pain—free and is called "unlimited electric gum". when chewed, the gum

creates a small current, which tricks the tongue into experiencing different tastes. now to california, where richard taylor has been looking at adobe's creative vision of the future. whether it's intelligently animating your flat 2d photos so they appear to have depth, cropping your regular videos to keep the important action in frame for vertical video sites like instagram, or making smart selections of objects inside your videos to realise an artistic vision — these are just a few of the ideas dreamt up by the engineers inside adobe. even though they may not all make it into the product pipeline, they're designed to inspire the creative community to make their pilgrimage to the company's annual shindig. but this year, the message from adobe max is notjust about creatives,

it's about all of us. the silicon valley software giant now says it is easier than ever for us to express ourselves whenever and wherever inspiration strikes. ready? yeah. a better example of this is probably the upcoming photoshop for ipad. notjust a cutdown version, the full desktop app reworked for touchscreen. but not everyone's impressed. photoshop on the ipad — it will make apple users happy, but they could've put this out before. there are other rival apps out there, which are pretty impressive. and to be honest, i think they're beating adobe at their own game. accelerating our creativity is another big push here and adobe's put its artificial intelligence engine sensei at the heart of it. here, adobe's after effects software is able to remove the horse from a moving scene in just a few clicks. something which would've previously been pretty challenging if you weren't a pro. similar ai tech lies behind its new mobile video editing app. aimed at amateur video creators, bringing in several pro features like colour correction and even audio clean—up.

but premiere rush is a somewhat ironic name, given that adobe's largely dragged its feet in serving the youtube generation until now. we don't ship products until we're ready. and to your point, it's taken years to make sure that we could have a phone, tablet, desktop, cloud first experience, so customers can pick up where they left off across different surfaces and make professional grade quality output. the other buzz right now is around ar. adobe's new app project aero makes creating these augmented reality experiences more straightforward. here, a photoshop file can be immersive by little more than dragging and dropping it into the app and then separating out the layers. this kind of immersive experience is attracting particular interest in retail. with brands keen to exploit the potential of ar, and adobe itself is keenly aware the currency of its own brand rests ultimately on its ability to keep one step ahead of the competition. that was rich.

and now, back to japan. here at the research labs of ntt docomo, the country's largest mobile network operator, something new is about to take off. it's big, it's flashy and it's rather noisy. (shouts): what could it possibly be? oh, it's a flying display! yes, this is the world's first spherical drone display. the externalframe is made of eight rotating strips, each consisting of 320 leds, which when spun rapidly, create the illusion of a solid sphere. we would like to make a new special platform to present our information anywhere in the sky, for advertisements or entertainment, or

guidance in a disaster. of course, everything about this technology will have to get smaller, more reliable and longer lasting before it becomes useful. at the moment, this thing can stay up for a maximum of three minutes. ok, well, now it's time to pop back to ceatec to see what emily and dan have found for us this time. this is notjust a great ride. it's one of the first systems to use an 8k projector above us onto a curved mirror to give us this real immersive experience. and the great thing about this is it's quite small. so you can pack it up, it's quite portable, you can take it pretty much anywhere. and they're hoping they can use this to go around to hospitals and places that maybe don't have access to go to the cinema or to a theme park. laughter time for me to

get ready for tokyo 2020. this is fujitsu's 3—d sensing technology. a laser is scanning my body every second to pick up on 18 different points and joints. these are then turned into a 3—d representation that can be played back frame by frame. and it's hoped that this technology will be used to help judges evaluate gymnasts in competitions in the future. it could also help gymnasts hone their technique, give insight to live audiences through its app, and be used in physiotherapy. ok, slick moves, emily, but take a close look at this. japan is on the cusp of a tv first. this is sharp's very impressive second—generation 8k tv on sale next month. but the real news is that the broadcasting of 8k starts on 1 december this year by the national broadcaster, nhk, so there will be something to watch. oh no, hang on.

this is definitely something to watch. yes, ok, ok, virtual baseball was a bit hit... homerun! ..and miss. and i wasn't having much luck with virtual fishing either. it's heavy. this teleha ptic setup by keio university means i could be at home while the fishing rod that's copying my movements is out at sea. that may, of course, mean that dinner is a little late. now, if emily has no luck catching those robot fish, she might like to try the robots here at this lawson store. hello? hello. it's the overenthusiastic shop assistant there. lawson is a big firm injapan.

a bit similar to tesco back home. they serve food, but what they're finding is that the population in japan is decreasing, the working population, so fewer people able to work in stores. so, our shop assistant at the top will knock us up a salad according to our allergies or our health concerns, she will know those automatically in the future. and in a few years' time, lawson would like to introduce these cooking robots, to cook us something live in store as we shop. today, dumplings are on the menu. now, another thing that may be of interest to japan's ageing population are these. they may look like normal glasses, but if i press the touch sensor on the side, you may have seen a little flash, and what that was was liquid crystals inside the glasses shifting orientation and changing the focus, meaning it's easier to see things close up, just like bifocals. now, the upside to these is you can then turn them off and it goes

back to your regular prescription. so, how are we gonna decide who's found the best tech this year? let's ask the creepy rabbit cum shop assistant to make the loser look silly. you've got a little bunny bag now as well to go with it. thanks. great, it's just what i wanted. it's worth coming. beautiful, dan, just beautiful. and we'll finish with something mind blowing, eye—popping and jawdropping. i can't even walk in. it's messing with my perspective. this is borderless. the latest otherworldly experience from digital art collective, teamlab. this amazing space is their first permanent home in odaiba in tokyo. a 10,000 square metre magical transcendent world of projected art that's never the same twice. this is just astonishing.

it really is alive. the exhibits react to your presence and your touch. nothing's just played on loop. everything is changing and reacting all the time. behind the scenes, 520 computers and a70 projectors bring to life the work of cg! artists, engineers and architects. even in the cafe, tea breaks are living works of art. all of the drinks come with a white foamy topping and that's because when you put them down, flowers bloom on your beverage, floating away as you sip. make artworks and artworks, it's also no boundaries. because it's not made by materials. for us, it's paint, it's light, and the canvas is everywhere. it certainly is borderless.

some of the art just doesn't stay put. characters leave their point of origin and wander into other rooms and across other works. visitors even get the chance to add their own art to the exhibition. colour an animal, scan it in, and it comes to life, joining the user—generated menagerie that's flying, swimming and crawling the floors and walls. the other reason it's called borderless — thanks to all the mirrors, some of the works just seem to go on forever. it's certainly a place where time becomes irrelevant until you really have to leave. and that is it from japan for this week. i cannot think of a better way to end the programme. don't forget, we live on facebook and on twitter

and we will put up loads of backstage photos and videos there. the address is @bbcclick. thank you so much for watching. we'll see you soon. hello there. temperatures in some southern areas got close to 20 degrees on wednesday with sunny skies overhead. thursday will bring a bit more in the way of cloud, not completely cloudy but often cloudy. still dry for many. we start off the day with a few mist patches where the skies have

remained clear through the night, but generally speaking quite a lot of cloud through the day. the best of cloud through the day. the best of the sunshine to the east of high ground for eastern england, east wales, for example. northern scotla nd wales, for example. northern scotland seeing cloud in our racks of rain, temperatures down a little on where they have been. during thursday night, we bring this cloud and rain across scotland, northern ireland, down in the england and wales. behind that, real change in the view of the weather. something very, very cool indeed, some clear spells and the showers. as we head towards the weekend, it will feel cold. a biting northerly wind, some sunshine and showers as well and the risk of some frost and some ice. welcome to bbc news — broadcasting to viewers in north america and around the globe. my name is martin syanford — our top stories. explosive devices are sent to leading democrats including barack obama and the clintons. president trump says such behaviour

has "no place" in america. any ads or threats of political violence are an attack on our democracy itself. —— any attacks. —— any attacks. in our second special report on china's muslim minority, we hear from those who have fled the country, leaving families behind. the saudi crown prince vows to punish all the "culprits" responsible for the murder of writer jamal khashoggi in turkey. and america's growing addiction to drugs. we hear from those on the frontline of a public health crisis.
