In under an hour we speak to one of the scientists behind a new blood test. Good morning. Its 8am in singapore, 1 am in london and 8 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 But china says the treaty is now just an historical document.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. Lets take a look at some of the days other news.

It doesnt sound pleasant, does it . 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 fourth ofjuly. Critics have accused him of politicising the national holiday. Chris buckler reports from the capital. rant every year on 4july, 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. Youre watching newsday on the bbc.

Britain summons chinas ambassador amid a war of words over this weeks protests in the territory. More than a Million People have been ordered out of their homes injapan because of torrential rain and flooding. Lets take a look at some front pages from around the world. 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, while the South China Morning Post continues to look at the protests in hong kong, saying a chinese taskforce in shenzhen has been closely monitoring events for nearly a month. It also shows this picture of a Police Officer gathering evidence from the Central Chamber of the legislative council. And in europe, most of the news focuses on who is filling the eus topjobs. The Financial Times reports on ursula von der leyens nomination as president of the European Commission, which has led to surprise in germany, where the defence minister has suffered many negative headlines. 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. Ive been speaking to assistant professor huilin shao, who led the Research Team at the National University of singapore. She explained why Early Detection is important. So as you mention, worldwide, there are over 50 Million People who are suffering from dementia, and of these patients, a very High Percentage of them are suffering 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 is a very painful disease with a very huge Socio Economic cost, there remains a very urgent need for Early Detection of this disease, so that we can stop this increase or reduce this increase in 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, there are 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 advances. The first is that we developed a nano sensor, which is very sensitive. Its 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 7 0h, 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. 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 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 were disallowed goals, sending offs, 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 were likely to neutralise each other for long periods. And it was a bit of a one for the purists, if im being brutally honest. Both teams hit the woodwork. 0ne hit the post, the other one 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 Jackie Groenen goal in the 99th minute to separate these two. And the netherlands, who are the european champions at the moment now, will move on to theirfirst ever world cup final. And its some feat, you know. This is only their second ever world c
