the latest headlines from bbc news. i'm gavin grey. president—elect donald trump has praised russian president vladimir putin, after mr putin said he will not expel any us diplomats in response to washington's expulsion of 35 russians. writing on social media mr trump said, "great move on delay. i always knew he was very smart." police in rio dejaneiro are questioning the greek ambassador‘s wife and two other people on suspicion of involvement in the envoy‘s killing. investigators say the ambassador‘s body was found in the boot of a burnt—out car. the nationwide ceasefire in syria is now over 2a hours old. while it appears to be holding in most areas moscow says it call on the un security council to back the deal and support new peace talks. now on bbc news, it's time for click. this week:

a click christmas with digital jumpers, hatched technology and thai fighters. hello and welcome to the annual clickmas get—together. cue christmas cheer. have we got everyone here? jen, nick, steve, and kate russell. hello! hello, spencer. i have sought out a little christmas gift for you. 0h, out a little christmas gift for you. oh, thank you very much. it's an egg. it is an egg. right. inside it isa egg. it is an egg. right. inside it is a hatchimal, which is the latest robotic interactive toy. it's got loads of sensors. and your child

basely has to nurture the egg in order to hatch it and then it breaks its way out of the egg and then you teach it games and you have to care for it basically. fabulous. you have to feed it and play with it. so i'm going to be a daddy. you're going to bea going to be a daddy. you're going to be a daddy, congratulations. thank you. i shall name you... later. right. better put it somewhere not on the table so we don't accidentally eat it or something. i don't know. we have had some inventions —— adventures this year. in fact, click is a 52 week a year production so it's difficult to get the whole team in one room. this is the whole team in one room. this is the kind of thing we've been doing this year. iamso this year. i am so luke skywalker. my bad. half a billion pixels on display here. one of the most extraordinary athletes you will see this year.

the world's highest glass walkway. this is absolutely. stunning. this week we are going to look back at some of our best bits from 2016, and we start with a really positive story in a place that you wouldn't think there was any positivity at all. earlier in the year, jen wentjordan, to the border with syria, to look at some of the innovation happening in syrian refugee camps there. i went to zaatari, the biggest refugee camp in jordan. there are 80,000 refugees living there and it's actually a community of makers. i was fascinated to find out, and they are making some incredible technology out of some very rudimentary things in the camp. the main street here in zaatari is called champs elysee. it is a play on two things, the champs elysee in paris

and the word syrians refer to damascus by, cham. there are several hundred shops lining this street and you can find everything from bridal dresses to vegetable shops, barbershops and even quite a few mobile phone shops. technology here is being used in inventive ways to ease daily life here. the camp is a community of makers and one of the most innovative people we met is safwan. three years ago safwan fled the violence in syria with two family members. they all have disabilities and struggle to get around on the unpaved roads. he wanted to have more independence and designed an electric bike around spare parts he found. the brakes.

giving refugees access to technology and education is the focus of a group called refugee openware. one of its start—ups is focused on fabrication technology, including 3—d printing. assam was an ambulance driver in syria and lost his leg in a bomb explosion. as well as customising his own prosthetics, he helped a young yemani boy, named zain, who lost part of his hand in a fire. they were able to include elements of zain‘s favourite cartoon

character, ben 10, in the design, all forjust 75 us dollars. assam also helped develop a 3—d printing system using haptic feedback for another syrian refugee named ahmed. he was blinded by a sniper shot that went through his eyes. the echolocation system helps guide him to walk around unaided. they are planning to open fabrication labs in a refugee camp in turkey and in the northern jordanian city of irbid. it is a small but positive step to harness the talents of people forced into exile and help integrate them into a new country. brilliant. that wasjen, and for the next part of the programme, i have had to clear the room because there is a serious danger to human life in this next item. is that not right? it is exactly right. the last few years, one of the biggest gifts people have been getting is, of course, drones. now, for the next few christmases, a star wars movie will be

released as well. as it should be. exactly. combine the two and what do you end up with? star wars drones. hums star wars theme now, there is something special about these drones, isn't there, spencer? they are notjust drones we can fly about, we can actually engage in combat. they are armed with infrared guns, which means you can fly them about and then press the fire button. you are going to get your best anakin skywalker on, well, it would be luke skywalker because you have the x—wing and i have darth vader's tie fighter. when a shot is registered, we get a rumbling in the controller and you have got three lives there as well. feel the force. the force is strong in this one. talking of which, you met an amazing flying man this year. a man who flies like a bird. his name is yves rossi.

he has an apparentice now called vince, who is based out in dubai and he is thejet man. he has built and designed this enormous jet wing that allows him to fly in excess of 100 mph at about 5,500 feet. it is really quite remarkable. we went for a flight with him and saw what he does. jet man's training centre is based at this hangar in the desert outside dubai. today, i am going to watch him do hisjet—powered thing up close. how are you feeling? good. charged. ready to fly. in this hangar, yves and his team maintain thejet wings which are capable of flying at 189 mph. you are not flying solo anymore? no, that is the big advantage now, to have a friend with me in the air. vince.

vince has plenty of airborne experience as a three—time world champion skydiver. as a kid i would watch the magazine and i would see what yves was doing as a pilot and as a pioneer of wing shooting and flying. i would see who he was. outside the hangar, things are getting a bit noisy. this is why we got up early. our ride has arrived. with the chopper on the flight line, it is time for yves to become the jet man. no flight would be complete without an inspirational soundtrack. cheery music i notice that as well as lacking doors, this particular helicopter lacks seats in the back as well. ok, 20 seconds until launch.

that is without a doubt the most bonkers thing i have ever seen. so, we can just see yves in the distance. he is flying formation with the helicopter. there he is. he is going to fly parallel with the helicopter right now. oh, my word. you will believe a man can fly. he has got about eight minutes' worth of fuel on board that. here he comes again. so, we arejust coming in to land now, but yves is going to land by a slightly different method. just in the distance out there, you can see him. his parachute is deployed, and he will land right back

at his hangar. truly incredible stuff. as you can see, we have reached that part of the christmas dinner now. i will crack on though. my most memorable moment of the year was when i visited cern and the large hadron collider and had a jolly good cry. having a moment. we were really lucky to be able to see inside the collider and the cms experiment because they they had opened it up for cleaning. even better, we filmed the whole thing in 360, so you can take a peek inside. welcome to the largest particle physics laboratory in the world. right now, you are standing inside cern, the european organisation for nuclear research. you have got a view that very few people will ever see. we are about 100 metres beneath the swiss—french border and above you is just one of the experiments at the large hadron collider.

itself the largest machine in the world. in a few minutes we will head up there. on that cherry picker, to see what happens when you smash particles together at close to the speed of light. before we do, let me show you what kit you need to get things going that fast. so, here we are walking along part of the long circular tunnel that houses the lhc. that is it next to you, that is the large hadron collider. that collection of magnets. it is a 27 kilometre long loop. there are four experiments on the lhc and ten accelerators in the complex which, together, accelerate bunches of particles to close to the speed of light. this cavern contains the cms experiment. although there is nothing compact about it, if you ask me. this is one of the places that helped to discover the higgs boson.

so, that big shiny pipe above you is connected to the tunnels that we were just in. when the beams of particles are going fast enough, tiny adjustments are made to bring those two beams together until, right here, they collide. in an instant, the particles are smashed to pieces and it is these even smaller particles that the cms can detect. it is an enormous sensor that looks pretty fundamental building blocks of the universe. by using even higher energy collisions, the cern scientists hope to find other particles and explain mysteries like dark energy and dark matter which makes up 95% of the matter in our universe. this is big science performed on the tiniest of scales. that was cern in 360, and this is the clickmas table in 360.

everybody wave at the 360 camera. the brilliant thing about filming in 360 is you can do really weird things with the picture on normal tv, like this. but you can also feel like you are genuinely sitting in the middle of our table on a candle. if you go to the link on the screen, you can see us surrounding you, about to eat you. the man behind the 360 show is this man over here. steve beckett, who is wearing the beautiful augmented reality christmas jumper. why? what do you think of this? it is a little bit scary. terrifying. from one engineering marvel at cern and to another engineering marvel now that spans two mountains in china. dan simmons went to the oldest national park in china. tucked away on the edge of this world heritage site, someone has decided to build

a bridge from the middle of nowhere to the middle of nowhere. unlike me, they hope, the thousands of visitors who will come here will not be too scared to look down. 300 metres through the highest glass walkway in the world. these are the final days of construction for this three—year project, more than 300 engineers have worked through all weather conditions to build what is also the longest glass—bottomed bridge in the world. a breathtaking 430 metres. crossing the zhangjiajie grand canyon. the walkway itself is just 60 centimetres thick, so the challenge to keep everything stable has required some fresh thinking. 70 glass balls are to be positioned on the springs along the walkway. they have been designed to move to counter any swaying.

these curved railings will persuade up to 800 visitors to keep changing direction. offsetting the resonance caused by hundreds walking at a constant speed. our hosts were keen to show just how safe i was. each panel of the walkway has three layers of toughened glass held together by glue. here goes. shouting it looks like you can see the top glass has shattered here. shouting we're ok. laughter do you know what,

i think this might be safe. ok, guys, we get the point. that has to be the finest shot that anyone in this programme has shot in forever, surely. ok, fairenough. one of the other amazing things we saw this year was in zurich when we went to see the first bionic games. the cybathlon. that was brilliant. it was incredible to see the latest in robotic arms, prosthetic limbs, motorised wheelchairs, brain controls, an amazing day. it was also a competition for the people who created the devices. building and training for this very unique competition. disabled athletes, known as pilots,

will be competing using advanced assistive devices. it is the brainchild of this man, robert reiner, a professor for sensory motor systems at eth zurich. it is an event for people with disabilities who are allowed to use any kind of technology. that technology helps them to better perform in daily life activities, so we are focusing on the challenge of daily life and allowing technology to help people with very severe disabilities. each of the six disciplines will have qualifiers in the morning before the grand finals in the afternoon. how do you win? simple, get round the course or through the obstacles in the shortest time while incurring the lowest number of penalties. the powered arm prosthesis race is notjust about power, it is about precision

and reliability. the teams need to come up with the best ideas to help their pilots grip, twist and balance their way along the obstacle course. the race is designed to test how well pilots can work with their prosthesis to complete tasks that would typically be challenging for them. yes, this is the race where the mightiest tech in the world can be foiled by the humble clothes peg. what is the next challenge you feel you could reasonably overcome to better the product? the next thing that is a big technical challenge that would improve the functionality is the touch sensitive nature of the fingers. there is no feedback at the moment in commercially available hands for getting the signal back to the body. the ultimate victor was a group of biomechanical engineering students from delft university of technology in the netherlands. together with their pilot, bob ridoce, himself an expert in prosthesis, they went

for a slightly more established body—powered approach. this means that physical movements like reaching forward or lifting your shoulders are used to control the device. while this gold medal idea might have won the day, in the end, just crossing the line was enough to send most teams home happy. the wheelchair final was a much closer run thing for the four finalists, and again you can really see the variety of ideas and designs. the hong kong team went for these caterpillar tracks, which made short work of the rumble strips. that is not a wheelchair, that is a wheel tank. that lack of suspension really gave the pilot a rocky ride on the uneven ground.

and balance was the big issue as these chairs arrived at the stairs. the climax of the event, with three pilots all reaching them at the same time. as the hong kong pilot had to endure being thrown about, florian houser showed off the clever weight—shifting feature of the swiss chair, which ensured that he did not topple over. in the final seconds, the swiss team came from third place to beat hong kong by just five seconds. music plays cheering

now, that was a tiny snippet of what was a really special show. if you missed it or would like to watch it again, it is still on iplayer. just scroll back to october. it is nearly time to go. first we have to check on our hatchling here. how is it doing? it has hatched. there it is. it is a beautiful thing. wake it up. wake up, little hatchling. oh, dear. now it grows up and you teach it things and one of the fun things you can do is teach it to speak, so you can say happy christmas, spencer. happy christmas, spencer. joy, the world hasjust become a better place. it is for ages five and up, and the side—effect of it hatching is these tiny bits of plastic do

break off, so if you have young kids around, obviously be very wary that you shouldn't leave them to their own devices. these are a choking hazard. take care, but otherwise it is cute. delightful. one more world first that we took part in this year. this year, kate and i hosted click‘s first live show in front of a studio audience. is there anybody there? that was interesting. are you ready? yes. i said, are you ready? yes! let's go. click theme plays cheering and applause

now, if you were not lucky enough to be in the audience, don't worry. we recorded the whole thing, and we will be showing highlights and behind the scenes stuff from the show on the programme next week. thank you very much for watching our clickmas special. there is only one thing left to do, which is the words first 360 degrees cracker pull. merry clickmas. yay! double winner! 0h! good morning. some contrasting weather conditions to close out our final few days of 2016.

take, for example, yesterday. it was cold and foggy in the south—east pretty much all day for some of us. temperatures just a couple of degrees above freezing, and not much to be seen from the london eye. by contrast, into the south—west, it was a beautiful afternoon with plenty of sunshine, as seen by this weather watcher's photo in st ives. 12 degrees the high here, and it was mild in the north and west of scotland as well. but it is going to turn increasingly wet and windy. high pressure, though, into the south just hangs on, and so fog certainly going to be an issue. it is certainly worth bearing in mind if you are out and about on the roads early on, there could be further disruption to travel, as that fog may well be dense in places. so temperatures struggling just a couple of degrees above freezing, and it will be a pretty murky start. mild to the north—west, but that rain is on its way. but let's concentrate with the fog across east anglia, down into the south—east corner, and to the south of the m4 corridor. here, some of the fog could be dense in places. so it is going to be a cold, grey start, eventually that fog lifting to low cloud.

there will be a little bit of brightness, though, across much of wales and the north of england. you should get to see some sunshine, and that will stay with you for much of the day. across northern ireland, southern scotland, the winds picking up, the rain into the north—west, some of that turning quite heavy for a time, and that will gradually drift its way south through the day. we should get to see a little bit of sunshine into the north of england and north wales. hopefully the fog lifts away, and it may well feel just that little bit milder. a bit more of a breeze around, at eight or nine degrees here, ten or 11 further north. now, as we go into new year's eve celebrations, unfortunately that weather front a bit of a nuisance through northern ireland and northern england, perhaps into north wales as well. so it means a wet end to the year. behind it, colder, and there will be some snow showers. so i suspect, as the clock ticks towards midnight, that weather front will be sitting, really, through the north of england and into wales. to the north of it, showery, those showers turning increasingly wintry. to the south of it, it stays mild and quiet.

now, eventually, as that front sinks south once again, the colder air digs in from the north. so we start off new year's day with some wet weather moving your way through the midlands, eventually pushing into the south—east corner. so a pretty miserable new year's day here. further north, it stays cold and showery. it will be a colder day on monday, but at least there will be some decent spells of sunshine, and it stays largely dry as well. a warm welcome to bbc news, broadcasting to our viewers in north america and around the globe. i'm gavin grey. our top stories: brazilian police question the greek ambassador‘s wife on suspicion of involvement in her husband's killing. as russian diplomats prepare to leave the united states, donald trump praises president putin for not expelling us staff in retaliation. 2a hours on, syria's ceasefire is generally holding. the un security council will be asked to endorse the agreement and back new peace talks.
