The ice for the World Championship next week in michigan. Remember, you can get in touch at bbc 05. Talks to bring about a Global Nuclear arms ban are under way at the United Nations in new york, but most of the worlds Nuclear Powers are refusing to take part. The Us Ambassador to the un explained why the United States wont be signing this treaty. Is there anyone that believes that north korea would agree to a ban on Nuclear Weapons . So what you would see is the General Assembly would go through, in good faith, trying to do something, but north korea would be the one cheering, and all of us and the one cheering, and all of us and the people that we represent would be the ones at risk. And so weve a lwa ys be the ones at risk. And so weve always said that the United States thinks its important to defend the citizens of our country, butjust as important to defend our friends, citizens of our country, butjust as important to defend ourfriends, our allies and the rest of the countries that want peace in the world. Nada tawfik is in new york and joins us now. I guess the fact that the us and others are not backing the treaty puts a damper on things. Absolutely. We heard from japan, speaking in the General Assembly hall, they are the only country that suffered an atomic attack, and they put the point on this saying, if we have a nuclear ban treaty, but we have none of the Nuclear Powers signed up to it, and if this doesnt stop the development of even a single Nuclear Weapons, what is the point of all of this . We heard from other nations who support and agree with senator haley, and they think an International Framework is in place, and they think there needs to be step by step gradual approach to Nuclear Weapons, because they are concerned about national security. Those supporters of this would say that it is the only Weapon Of Mass Destruction that doesnt have an International Ban on it, and that should be the first step. What i dont understand here is, it was entirely pricked a ball that the us wouldnt sign up to this treaty, so why have the debate in the first place . They are hoping to get a treaty out of this and there is an argument that it of this and there is an argument thatitis of this and there is an argument that it is really a treaty without any teeth if it doesnt have the Nuclear Powers in it. But campaigners are hoping this will at least send a message. It will show that International Norms are against Nuclear Weapons and the proliferation of them, and they think it will force many nations the same way, the cluster ban or the Landmine Conventions have forced other states to change their behaviour and the way they operate. That is the main gimmick you hear from campaigners and supporters of this treaty. Their ultimate goal and ideal is for, late in the process, for the states to sign up to the treaty once they get it ratified. From speaking to the us and britain, the uk, and others, it doesnt seem like they would be interested in that. They see the npt as the goal of the nuclear free world. Nada tawfik, thank you. On wednesday, the british Prime Minister theresa may will trigger article 50. That starts the clock on two years of negotiations for the uk to leave the eu. But scotlands First Minister has a deadline of her own. Nicola sturgeon wants a second independence referendum for the people of scotland before brexit. Theresa may says its not the right time. The two leaders met today in glasgow. And we wondered, has the formerly warm relationship gone cold . Heres Scotland Editor sarah smith. Theresa may knows this could be awkward. Shes here to talk about her article 50 letter. Shes here to press her demand for a referendum on independence. So no handshakes, no press c0 nfe re nce , independence. So no handshakes, no press conference, just a couple of souvenir photographs that neither woman looks like theyre enjoying. By stark contrast, their first meeting, eight months ago, then it was called a good working relationship, now, Nicola Sturgeon says the pm has not listened to her on brexit, theresa may says that she will reject any request for a vote on Scottish Independence. My position is not going to change, now is not the time to be talking about a second independence referendum, because it would not be fair on the scottish people to make them make that decision when the facts are not clear and also because now is the time when we need to pull together to make sure we get the best possible deal for the uk, including the people of scotland. Im told the meeting inside this hotel was businesslike, cordial, and probably the longest meeting yet between them, the Scottish Government were expecting an offer of more powers for the Scottish Parliament after brexit, but they say they got no detail on that. When Nicola Sturgeon told the Prime Minister how she plans to make a formal request for a scottish referendum, the Prime Minister said simply, you know my position on that. The First Minister says mrs may agreed, the shape of the brexit deal should be clear in 18 to 2a months time, which is when the Scottish Government want to hold the referendum. We both agree, now is not the time to ask people to make the choice, but since we both appear to be in agreement as to when the terms of brexit will become clear on the timetable, that would underline my view that that is the right time. Ina in a speech to staff in east kilbride, she says she wants to build a more United Nations. But it is Scottish Independence on the agenda at the Holyrood Parliament tomorrow, and they will almost certainly vote to call for a second referendum. Lets bring you 0s sport now. Usa hockey, thats the Us Association for ice hockey, is holding an emergency meeting. Thats because their womens team is threatening to boycott the World Championships, heres the captain explaining why. She says usa hockey has been desperately searching for replacements, in case it needs them. Look at this, for example there has been support from sponsors and politicians, and we will see from the Mens National team, alan walsh, let me show you his tweet somebody who knows a lot about this, a lot more than me, aj perez, Sports Writer for usa today, whos been following this story. How much support would you say this boycott has . It is pretty much massive support. You mentioned the senators that came out in support, all over social media, the trending hashtag, and so much support, it has been impossible for them to field a team of replacement players. This is a big issue because the championships are being held in the United States, and the american womens team might not play. Exactly. Usa hockey would have to pay a fine if they dont play. It would look bad in front of all the International Teams in michigan. Not having a host team, it has been going on for 4. 5 hours. There has been no progress and time is ticking down. I know that technically, the men dont earn that much more than the women, but actually the male players have a lot more cash, dont they. Yeah, 98 nhl players have played in the olympics. If you are 18 usa player, you make millions in the nhl, there is a leak here that has been around for two yea rs here that has been around for two years for the women, and it has a top pay of 20,000 or 30,000. It is not really apples and apples. women dont get the living wage that they are asking for, and the championship is in a few days, what does american hockey do . Its been tough. Theyve been trying since last thursday to fill the team with players they have gotten from the under 18 s and under 16 s. They have gone down to high school and reached out of players that have been out of the game for a few yea rs. Been out of the game for a few years. They are paying women around the nation, and so far have come up pretty far short of filling an entire team. There is so much support for the boycotting women, they may not have a team and may have to pay the fine. Thanks for bringing us up to date. This is gerard nus. He was a member of ghanas football Coaching Team for the african cup of nations. That ended in february, but mr nus hasnt left ghana yet. Hes been staging a sit in at a hotel, because he wasnt paid for his work. Now though, the Ghana Football Association says it has finally managed to raise the funds to pay. Gerard nus all his outstanding bonuses on saturday. Mr nus has ended his sit in. He tweeted more sport to bring you. We have some extraordinary pictures from motocross. Theyre from the freestyle motocross World Championships, the fourth round took place in poland on saturday. This event is known as night of the jumps. one competitor broke his femur only six months ago, but he still managed to come third. But it was spains Maikel Melero who won. Its his second victory in a row. Quite extraordinary pictures. I have rather got my heart in my mouth watching that. We will move onto political story. European politics this time. You might remember dutch voters went to the polls on the 15th march. Almost two weeks on, Prime Minister mark rutte is still trying to form a new centre right coalition. Four parties will enter talks this week. Including left wing environmentalists groenlinks, led by this man, jesse klaver. Thats the dutch and what is going on there. Its germanys turn to hold general elections in september. Christian democrats leader Angela Merkel will try for a fourth term as chancellor and shes just had some good news. Its about saarland, a small german state which had an election this weekend seen as a significant test of voter sentiment. Saarland was run by a coalition whose makeup mirrors national government, thats a mix of merkels cdu and the social democrats. The results are in. The Christian Democrats won with 40. 7 of the vote. Thats up by more than 5 since the last election. The sdp, led by former eu president martin schulz, polled 29. 6 . Heres a somewhat relieved Angela Merkel. Translation obviously, the citizens have seen that this coalition is a coalition that governs well. We have a lot of hard work to do. It is going to be a difficult campaign, but we have all the chances. I have a lwa ys but we have all the chances. I have always said, it is in the hands of the cdu.

Mr navalny was one of hundreds of demonstrators detained at rallies across russia. This is yogi adityanath. Hes just been appointed as head of uttar pradesh, indias most populous state, home to more than 200 million people. Hes a divisive figure, because hes a hindu nationalist, in a State Where18 of the population is muslim. One of his first acts was to order Police Officials to close down slaughterhouses deemed as illegal in the state. Critics say the ban is being unfairly applied, and that it targets muslims, who own most of the slaughterhouses. Justin rowlatt has more on this appointment. The crowd celebrates the return of a conquering hero. Yogi adityanath wears a saffron robe of a hindu priest, but he is also a firebrand politician. They wouldnt know it today. Translation i promise to stamp out corruption, to work for everybody, and to end mafia rule. Out on the streets, you see the passion he inspires. Yogi adityanath has been repeatedly accused of Stirring Hatred between hindus and muslims. He was once imprisoned for incitement to riot, and has a history of inflammatory remarks, and he is now one of the most powerful politicians in india. Yogi adityanath is a man who once said, if one hindu is murdered, 100 muslims should die. There are 170 million muslims in india, and not surprisingly, many are worried. They shouldnt be, says one of the top leaders of the ruling party. Some people have apprehension, i do appreciate. Why only advise them, whatever is in the background remains in the background. You cannot change it. It remains. Yogi adityanath will prove that he is committed to the same agenda that the Prime Minister is pursuing. Yogi adityanath was the Prime Minister is pursuing. Yogi aditya nath was appointed the Prime Minister is pursuing. Yogi adityanath was appointed by the Prime Minister after a Landslide Victory in the state elections earlier this month. The choice is being seen as a decisive moment in mr modis leadership of india. Being seen as a decisive moment in mr modis leadership of india. You wonder whether the veils have fallen, and whether or when you re move fallen, and whether or when you remove the moss, what you see behind this Prime Minister that harps on about development and this inclusive paradigms, actually the mask is a. Four is behind this mask, you have a very divisive man, who believes that india isa very divisive man, who believes that india is a country of hindus only. Yogi adityanaths india is a country of hindus only. Yogi aditya naths political career began a quarter of a century ago in the unrest that followed the destruction of a 16th century mosque bya hindu mob. Hes destruction of a 16th century mosque by a hindu mob. Hes vowed to build a hindu temple on the site, and that Isa A Hindu Temple on the site, and that is a move that risks reopening one of the deepest wounds in modern indian history. Scientists from New York University have published a new theory which could explain why our brains are so large. Their new study, which examined the skulls of primates including monkeys, lemurs and humans, claims its down to diet, not social behaviour. Our science reporter Melissa Hogenboom has been to new york where they carried out the research. For the last couple of decades, a key idea has been that the social Brain Hypothesis was the reason, the key Driving Factor for a big brain. This suggests that social factors are the main thing that helped us grow such complex lead large brains. You and i conversing right here, we can do that because our brains have complex language abilities, and we are allowed to do this because in human evolution, there were large groups of us that supported each other and help each other find food. We need a complex communication, so do social abilities were the key binding factors of our group. The idea being that the group drove the developing brain. What about the new theory now . The study looked at 140 primate species, including monkeys, apes and asked, and advertised what they ate, social structures. They found that when they put these ideas together, the key Driving Factor was actually food. It wasnt just food, the fact that animals that eight calorie high food such as fruit, tended to have bigger brains. That came first, then social groups became important. And you had the outlier, the orangutan, who has a big brain, but not big families. They are solitary creatures that go round in small groups to avoid predators and to hunt together, but usually roam alone. They dont have large groups. That takes away from the social brain, because they have very large brains, one of the largest primates around. They were not included in the original analysis of the social brain analysis. And now ourfinal and now our final story. 25,000 people have been told to evacuate as a major Cyclone Bears down on australias north east. Cyclone debbie is expected to cross the North Queensland coast sometime in the next six hours. In the next four hours. Its currently a category four system but forecasters say it could go to category five the highest level. The Whitsunday Region will be hardest hit. Winds of up to 275 kilometres an hour are expected, as well as tidal surges up to seven metres high. This is what australian Prime MinisterMalcolm Turnbull said about the situation.

Tweeted by abc reporter rachel riga. A huge tree was toppled by the winds. And this is the scene right along the impacted coast line. People sandbagging their homes and businesses in preparation forflooding. We will keep you up to date on that. We will keep you up to date on that. We have reported recently on floods in per room said to be the worst in two decades. Just to update you, today, we have heard that farms and cut branches in the country have been particularly badly hit, and have not received enough support from the government. Cattle ranchers. Many farms have been turned into mud swamps after the heavy rain and flooding. That is the situation in per roof. That is all your round up of news from the outside source team. Think you very much for being with us. Hello. Brain for all of us later. But we cant complain. Time for a reality check. Lets head down under where severe Tropical Cyclone debbie has made landfall on the queensland coast, bringing violent wind and flooding rains. It will no longer be a cyclone as it heads towards brisbane, it will bring major impact, all the rainfall has to go somewhere. We will keep an eye on that over the next few days. Closer to home, we have our own game changer, a huge area of low pressure dominating the atlantic. Nothing as extreme as cyclone debbie, but what is it ambled across the atlantic in oui is it ambled across the atlantic in our direction. In fact, is it ambled across the atlantic in our direction. Infact, at is it ambled across the atlantic in our direction. In fact, at the start of the weekend, it will be on top of us. Of the weekend, it will be on top of us. No major impact, but yes, there will be rain around by then. At the moment, it is tryjust about everywhere. Showers getting into parts of wales and western england in the morning. The main push will be through Northern Ireland to south west scotland. Cloud across scotland, so cooler. Further south, any sunshine will feel pleasantly warm, mid to high teens with light winds. Through the evening, another bout of damp and dreary weather, and heavy rain in northern and Western Areas through wednesday with a strengthening wind. Further south and east, despite cloud on wednesday, it will stay mostly dry and pretty mild. Mid teens and cooler across the Eastern Scottish coast. Over the following few days, further fronts come coast. Over the following few days, Furtherfronts Come in coast. Over the following few days, further fronts come in as the area of low pressure begins to arrive. But the focus of the rain for the time being is across northern and Western Areas. At the same time, dragging in warm airfrom the near continent, watch how it turns orange across east anglia and the south east, Nudging Higher to bridges. Further north and west, more cloud, rain and breeze, nothing like as warm. We end the week with a cold front pushing the warm air away. So a fresher feel for all of us. Away. So a fresher feel for all of us. Circulating around the area of low pressure, we will see showers. Difficult to get the detail right at this range, but expect a showery end to the week with blustery winds. There will be sunshine, but we will have lost some of the warmth at this stage. We start the weekend on a showery note as the pressure sits on top of us. More prolonged rain in some places and cooler by then as well. Low teens, typically 12 or 13 at best. Under the area of low pressure, which as you recall has travelled all the way across the atla ntic to travelled all the way across the atlantic to arrive on top of us just in time for the weekend, and that low pressure is formed in a dip in the jet stream. The jet stream is to the jet stream. The jet stream is to the south of us at this stage. We are on the cools side of things. As we head into next week, Thejet Strea M We head into next week, Thejet Stream will shift its way back northwards again. Although there may be rain in the far north west, those of us clear of the jet on the Southern Side of it, things will warm up again. Changes once more as we head into next week. It looks like after the shower restart to the weekend, as the jet heads north, like after the shower restart to the weekend, as thejet heads north, it will turn drier in the south and begin to warm up again. Some changes ahead, andi begin to warm up again. Some changes ahead, and i will update you again once more tomorrow. Good night. Tonight at 10 police say theres no evidence to link the westminster attacker with so called islamic state. But they say Khalid Masood, who was described by is as one of their soldiers, had clearly been interested injihad. Masood drove his car at over 70 miles an hour across westminster bridge, hitting dozens of people in his path. I would more describe him as somebody whos been exploited, and a man who is clearly a lone actor, who has come up from the basement, so to speak, to commit a murderous and cowardly attack
