Theyll face the us. Diagnosing dementia in under an hour we speak to one of the scientists behind a new blood test. Good morning. Its 7am in singapore, midnight in london and 7 in the morning in beijing where an angry war of words has broken out between china and britain over the demonstrations in hong kong. It comes after British Foreign secretary jeremy hunt warned of serious consequences for china if the rights of People Living in the territory were infringed. Beijing has accused the uk of indulging in what it called colonial era fantasies. Our Diplomatic CorrespondentJames Landale has more. The aftermath of an invasion. This was hong kongs parliament today, where they were beginning to clear up the mess left by protesters on monday. For many pro democracy campaigners, their demonstration was peaceful. But for some, it was violent, forcing their way into the legislative council, where they wrought substantial damage. Damage that also had diplomatic consequences in london. The uk government chose to stand on the wrong side. It has made inappropriate remarks. Chinas ambassador said britains support for the demonstrations was wrong, disappointing and hypocritical. It had damaged uk china relations. We strongly condemn and oppose the gross interference in Hong Kong Affairs and chinas internal affairs by the british side. I call on them to keep hands off hong kong. What upset the ambassador was the warning from the foreign secretaryjeremy hunt that there would be serious consequences if china diluted hong kongs freedoms, and the promise from borisjohnson that he would back the demonstrators every inch of the way. The row centres on the joint declaration agreed by britain and china in 1984 that in future, hong kong should retain some autonomy and freedom. This meant that after the handover in 1997, hong kong would exist under a so called one country, two systems policy. Britain thinks that until the declaration expires in 2047, hong kong should keep its freedom. But china says the treaty is now just an historical document. Theresa may said she had been shocked by the violence, but emphasised that the majority had marched peacefully and lawfully. Its vital that hong kongs high degree of autonomy and the rights and freedoms set down in the sino british joint declaration are respected. I have raised my concerns directly with chinese leaders, as has my right honourable friend the foreign secretary and other ministers, and we will continue to do so. Jeremy hunt did that in a tweet, telling the Chinese Government that good relations between countries are based on Mutual Respect and honouring the legally binding agreements between them. He also summoned the Chinese Ambassador to the Foreign Office, where he was told by britains top diplomat that what he had said was both unacceptable and inaccurate. Its rare for the Chinese Embassy to hold a news conference. Its even rarer for ambassadors to be so outspoken. The question now is whether this war of words escalates and causes lasting damage to britains relations with china. James landale, bbc news. Our china correspondentjohn sudworth has been looking at the likely impact of this row on relations between the uk and china. We are of course meant to be in the middle of a golden era, a phrase coined in 2015 by the camera government. Some people may see some signs of that, that was the half £1 billion trade deal signed last month but there is a sense that the talk is never matched the reality. That the uk and china often dont share the uk and china often dont share the same values, on issues like hong kong. That said, the pushback this time has been unusual. The rhetoric is growing increasingly heated. The latest from the Chinese Foreign ministry here in beijing accusing jeremy hunt of basking in past colonial glories. There is a glimpse in that that china senses the balance of power is shifting and also a certain advantage. It is more than capable of sending countries with which it disagrees into the diplomatic and economic deep freeze and it knows that it is up near the top of the uk wish list for a post brexit trade deal. Lets take a look at some of the days other news.

This accident is the worst deep sea accident of its kind in russia for more than a decade and both president putin and the defence minister referred to it as a great tragedy.

Well start with the japan times, which reports on the us reacting angrily to a chinese Missile Launch in the disputed south china sea. The pentagon called chinas test of anti ship Ballistic Missiles disturbing.

So for as long as they are hydrated, i am confident that they are going to be ok. But we cannot leave any stone unturned. To washington, where preparations are underway ahead of what promises to be Independence Day with a difference this year. President trump has ordered a military parade of tanks for this ajuly. Critics have accused him of politicising the national holiday. Chris buckler reports from the capital. Every year on ajuly, huge numbers gather here at the National Mall in washington for Independence Day celebrations. But this year is going to be a little bit different. President trump is putting on what he calls a salute to america. He promises it is going to be a show of a lifetime, and you can see just how much work is going into it here at the lincoln memorial. We believe that about 2. 5 million has been diverted from Us National Parks funds in order to pay for some of this, but actually, we dont know how much it is going to cost in total. Mr trump is promising tanks, flyovers and fireworks. This is going to be a show of military might, as well as a thank you to americas troops. Although some of the pentagon are said to be a little concerned that this could become political. The armed forces want to stay away from that, but ultimately, it is up to the president. Right at the centre of events, he will deliver an address from here in front of the iconic lincoln memorial. White house officials are insisting that that speech will not be political, it will be a celebration of service. But of course, that depends if President Trump sticks to the script. Sometimes he doesnt. And it is worth pointing out that some of the best seats here have been reserved for Republican Party supporters and donors. Democrats say they have not been given any tickets. This is not a donald trump rally, and therefore the audience will not be filled full of his supporters necessarily. And how they will react if he gets political that will be interesting. And there is another question for organisers, and that is to do with the weather. Thunder and lightning has been forecast. If there is a downpour, that could have a massive effect on the half an hour of fireworks that have been planned. Dementia is often called one of the biggest Public Health crises of the 21st century, with around 50 Million People affected worldwide. So imagine if doctors could diagnose alzheimers disease, the most common cause of dementia, before symptoms appear. Well, researchers here in singapore have invented a blood test that they believe can do exactly that. For more on this, im joined by assistant professor huilin shao, who led the Research Team at the National University of singapore. Thank you so much forjoining us. Thanks for having me. Firstly, tell me about dementia. Why is it such a huge issue . So as you mention, worldwide, over 50 Million People are suffering from dementia, and of these patients, a very High Percentage of them are suffering from alzheimers disease, which is a majorform of from alzheimers disease, which is a major form of severe dementia. From alzheimers disease, which is a majorform of severe dementia. And with a global ageing population, this number is predicted to increase very dramatically over the next decade. And what i think is also very distressing about this number increase is that, despite that this isa increase is that, despite that this is a very painful disease with a very huge social, economic cost, there remains a very urgent need for Early Detection of this disease, so that we can stop this increase or reduce this increasing numbers. So tell me about your invention, and how significant that is. So alzheimers patients typically show a progressive decline of cognitive as well as physical capabilities. But long before these physical symptoms or clinical symptoms actually appear, these tiny molecular changes that can happen in the brain. And these include molecular changes involving the aggregation of proteins, which form these very sticky patches of proteins that kill brain cells. And that leads to a cognitive as well as physical decline. So what my team at the National University of singapore aims to do is to develop a new test that can measure these very early molecular changes in the brain, before these physical symptoms appear, and through a blood test. And what we have done is that we are able to achieve this with two technology devices. The first is that we developed a nano sensor, which is very sensitive. It is over 10,000 times more sensitive than conventional technologies that are available in the clinic. And with this technology, we are also able to pick up the most reflective form of these proteins, the aggregated proteins, the bad population of these proteins, directly from blood, to reflect very accurately the early molecular changes in the brain, at the very early disease stage. So whats next . Do you hope to see this test being carried out in hospitals around the world . Test being carried out in hospitals around the world . Definitely. So what we hope is that we are able to expand this test, to investigate more of these diseases, and also to expand this test to involve more patients. And i think that by using this type of technology, we can bring in many new opportunities for intervention, as well as disease management. For example, by Early Detection of this disease, we will be able to help patients, as well as families, to better prepare and cope with this disease. There are also therapies that are available that can target some of these very specific symptoms of alzheimers disease. So that helps patients to retain functional capabilities for a longer period of time. That sounds very remarkable stop thank you so much forjoining us this morning. Thank you. What a difference a day makes in the womens world cup. After the drama of the match between england and the usa, we saw a much safer game between the netherlands and sweden, with the netherlands winning1 0 in extra time. They will take on defending champions the usa in the final on sunday. Seth bennett from bbc sport was outside the stadium in lyon. Its very difficult, isnt it, when you compare it tojust its very difficult, isnt it, when you compare it to just 2a hours earlier, when you had all of the hype, but then you had all of the drama, of england against usa, where usa eventually came through. They we re usa eventually came through. They were disallowed goals, sending office, saved penalties, all sorts going on. It was always going to be very difficult for the two teams to follow that, particularly when you took probably the best tactically defensive team in sweden against a really good attacking team in the netherlands, and two sides that would likely to neutralise each other for long periods. Would likely to neutralise each otherfor long periods. And it was a bit of a one for the purists, if im being brutally honest. Both teams hit the woodwork, when hit the post, the other hit the crossbar, with the aid of the goalkeepers just getting little fingertips on them. But once we did get into that extra time period, all of a sudden then the netherlands really seemed to spark to life, and it took a groenen goal in the 99th minute to separate these two. In the netherlands, who are the european champions at the moment now, will move onto their first ever world cup final. And it some feet, you know. This is only their second ever world cup final, so for them to go on and get the chance to take on the is a big, big pat on the back for what they have been able to do with womens football in the netherlands over the last ten years, really. So we got the reigning european champions, the netherlands, facing the reigning world champions, the usa. Honestly, do the netherlands stand a chance . Well, look, i can make a case for them, if you like. The americans are red hot favourites. But what you say about the netherlands is they have plenty of attacking capabilities in there. Their striker, who hasnt had the greatest of tournaments as yet, but she is somebody that causes a massive threat in every single game that she plays. They have a player who can run the whole of the midfield, they have a player on the right hand side and she flies. Shes got so much peace out there. And if they play as a unit and they can force down the field and give the americans no time on the ball, then they have a chance. The question for me is defensively, are they going to be good enough . They have shown in this game against sweden that they are good defensively when they stay disciplined, and they did a really good job of that here. But can they do it in back to back games. And lets not forget here that the americans have been sitting in their hotel with their feet up, having i am sure a nice glass of fizzy water this evening, watching the netherlands slug their guts out for a full 120 minutes. They will be better rested, and that 2a hours could prove to be key.

But in other places it will look and feel very different. This is how it looked in the far north of scotla nd is how it looked in the far north of scotland on wednesday. On the satellite picture, you can see in the way in which this cloud has been approaching, putting in from the north west. And as this cloud makes it more progress, we will see some outbreaks of rain. So as we head through thursday, ran initially across the northern and the Western Isles will increasingly spread across the northern half of mainland scotland. The heaviest rain always across hills in the west. To the east of high ground, the rain very showery, very patchy in nature. More cloud filtering into northern england, Northern Ireland through the day, but the further south you are, we are going to see quite a lot of sunshine and some real warmth. 2a degrees for birmingham, 26 degrees in london. So thats the sort of temperature we could well attain at wimbledon during thursday afternoon. Certainly sunny skies overhead. Very light winds as well. Day ends on a sunny note light winds as well. Day ends on a sunny note across light winds as well. Day ends on a sunny note across the southern half of the uk, but further north we have oui of the uk, but further north we have our cloud, we have outbreaks of patchy rain, sinking a little further southwards, and then a new push of slightly heavier, more persistent rain gets into the far north west of scotland by the end of the night. Quite a mild night, as well, lows of 11 to 15 degrees. So as we go into friday, High Pressure still trying to hold on across the south. Some fine weather here, but these frontal systems will continue to bring some outbreaks of rain across the north of the uk. Still a lot of cloud for Northern Ireland, north west england and scotland, some rain once again putting down across the northern half of scotland through the day. Ahead of that, in the sunshine, some real warmth. 26, maybe 27 degrees. But underneath the cloud, with the outbreaks of rain, it will feel cooler. 17 degrees in aberdeen, 18 in belfast. And that is a sign of things to come. Because, as we move out of friday into the weekend, these frontal systems in the north will make some progress further south. And as this cold front here move southwards, it will open the door to some cooler air. The winds switching round to north or north westerly s. This band of sinking southwards, maybe getting stuck across southern england, south wales for a time. Could be the odd spot of rain here on saturday. Elsewhere, patchy cloud and sunny spells but with those north or north westerly winds, not especially brisk for most of us. Just bringing a slightly cooler feel. So temperatures that in degrees in aberdeen, maybe 22 in london. And we keep those slightly lower temperatures as we head into sunday. A lot of dry weather, a lot of cloud as well, but some spells of sunshine. This is bbc news.
