Fo ur americans already in need, the trade war is a burden they just cannot afford. Laura for those watching on pbs and around the globe, welcome to world news america. It has been a year since the akmocratic republic of congo declared an outbf the ebola virus. Since then, 2700 people have become infected and 1800 have died, making it the worst outbreak in the countrys arstory. Neighboring nationtaking more precautions, fearing the diseas the World Health Organization has declared an International Health emergafcy. Our soutca correspondent anne soy reports. Anne it takes a lot to beat ebola. Those who seek treatment have a better chance of survival. T buat the heart of the outbreak, conspiracies and violence drive infecti this Treatment Center was much smaller when i wasast here six nths ago. N the expaeaks to how big the outbreak has grown every time aase is confirmed, this team is sent to decontaminate everything the patient touched. But as many as a quarter of all cases dont come forward, and that only fans the flames of the deadly disease. Me ommunities have been hostile. So we are told meone has died of ebola here, and the funeral is t king place. But strangers are lcome. There have been attacks on alth workers. We know of fellow doctors who were killed. That has a negative impact on the fight against this epidemic. E anne it is rst outbreak of ebola in a war zone. More than 300,000 people have fled their homes in the northeastern province. In this village alone, 49 people were killed. A scorchedearth attack, a clear message to them that they are not welcome back. The u. N. Has its biggest peacekeeping force her trying to pacify a region thas known no peace for decades. But camps like this one keep growing, and farmers who have lost everything are forced to wait for donations. Lost my husband and two children. We ran and hid in the forests until soldiers came to rescue us. Anne many families have been pushed closer to areas where there is ebola. Living right outside a big hospital and next toter set aside for suspected cases for ebola is nowhere near safe for them. The conditions here are just perfect for an explosion of disease. The outbreak has hit the biggest city in the region. Goma is a tranhuort and trade on the border with rwanda. But nothe challenge is to stop it spreading to neighboring countries. Anne soy, bbc news. Laura north korea has fired a new shortrange missile and it is the second weapons test by pyongyang in a week. Ta short time ago presidemp played down the launches when asked about them at the white house. Pres. Trump shortrange missiles, we never made re ent on that. I have no problem. We will see what happens. But these are shortrange ssiles, very standard. Laura a brief time ago i spoke with former u. S. Ambassador to south korea chris hill who joined us from denver. Should the president be worried about what is the third Missile Launch by north korea in two weeks . Chs there is no question should be worried. The issue is why havent the talks started after his famous, or infamous, wk over the rder into north korea. His secretary of state has been dutifully saying that they will start soon, but there seems to be a holdup, and the holdup seems to be the fact that the north koreans will not accept any kind of u. S. Republic of korea military exercises, and they are now complaining about what is essentially a pretty lowkey tabletop exercise, a socalled summer exercise. In the meantime they had been firing off these missiles. I think the idea from the north korean Vantage Point is to say that these are short range, so we can debate whether we have an understanding of that or not. They are obviously trying to keep it below the threshold of a fullblown crisis. Whether there is a crisis or not, there is something to be concerned about, and the president has, i think, falsely taken the north purean issue and it in the solved category, and i think he is a long, long way from that. Laura the u. K. , france, and germany are saying that these Missile Launches are in violation of u. N. Sanctions. Why is the trump administratn reluctant to join the condemnation . Chris well, i think President Trump has gotten himself into a position where he doesnt want to say anything bad the north koreans. I think it is a violation of their Ballistic Missile bans, and, frankly, the Un Security Council resolution was first done by President Trumps Owner National security advisor john bolton when he was ambassador at the u. N. So he knows well that these are a violation. But clearly President Trump is hoping to keep the north korean issue in the category of something that he has had success with. It is pretty clear that he has not, ore has not yet paid the price the north koreans the nortlscale koreans want, a fullscale exercise ban, and an effort to weaken the u. S. South koreh alliance, wh what this is about. Laura these new missiles appeared to be portable, so say defense experts. Does that mean north koreaps deve new systems while talking about denuclearization . Chris i think so. They have had them under development for some time. Portable Missile Systems are a targeters nightmare. It is hard to find them and they can move around. It is very, very difficult to be prepared as we need to be in case north korea starts something on the penin much to be concerned about. The japanese are also very concerned about these shorterrange systems, and i think the japanese would take issue with the notion that we only had a b could somehow got intercontinental. There is much to be concerned about. As usual with the Trump Administration, there is virtually no diplomacy. Our secretary of state seems to make more statements to the American People than he does to allies. K we have a real problem and frankly, we have a very broad problem, but this is certainly a symptom of it. Laura ambassador chris hith, ks for being with us. In yemen, more than 30 people were killed after the rebel Houthi Movement attacked paradef near the city aden. Our correspondent is in yemen an d has sent this report.

So todays attack raises questis about whether their retreat has created a security vacuum in the south of the country. In another neighborhood today, more violence. This suicide bombing targeted a busy police station. It is unclear if the two attacks are linked. Utday it was a bold show of strength by the s and a message that even they can attack from thair. For the people here in areas under their control, there is fear spreading about how the coalition is going to retaliate. The government here is blaming the houthis backers iran for this misle strike. Once again foreign powers are accused of spreading misery in one of the worlds most beleaguered countries. Laura in other news, four four people have be killed during protests in sudan.

Last night the second set of demoatic president ial candidate took to the stage in detroit, and while thereas a heated debate over health care, immigration, and economy, most of the fire was focused on the front runner, joe bi after a lackluster first debate, he had to prove he could answer the attacks, and aseyou will they came from all sides. Mr. Castro it loo like one of fs has learned the lessons from the past and one us hasnt. Mayor de blasio you need to be able to answer the tough questions. I guarantee you if you are debating donald trump, he will not let you off the hook. Sen. Booker mr. V you cannot have it both ways. You invoke president obama more than anybody in this campaign. You cannot do it when it is convenient and dodge iotwhen it is laura for more on Key Takeaways from last night, i was joined by democratic strategisna beverly in chicago. Thanks for being with us. Joe biden was definitely the punching bag last night, but did he emerge with front runner status intact . Alaina i think we absolutely saw joe biden receive the punches from other contenders. I think there were five separate questions that were aimed at him from other contenders on the debate stage. I do think he is still going to remain the front runner becausec he hada lead in the polls and has such a solidified frontrunner status. But we sawim take some tough questions on immigration, particularly from julian castro. We saw him spar backandforth amala harris on health care. E it is clear oves are off amongst democratic contenders, and joe biden is still the target for the hits, if you will, from his other contenders on the platform. Laura there was a lot of criticism of president obamas lega last night. You worked for the obama administration. Do you think that is a sensible strategy, given how popular he is with democratic voters . Alaina i think there was a lot of pearlclutching about the challenges to president obamas legacy. I dont think the challenges were as dire as everyone has made it out to be. However, there were criticisms against vice preside f joe biden fo example, the obama administrations policy of deportation. I will say this, the obama administrations policies did receive quite a bit of criticism for mass deportations. However, the administratiodid follow the rules of due process and did t, as we are seeing today, execute the cruel and inhumane processes we are seeing under the ump administration. Laura we have seen a lot of progressive policies articulated over the last twnights, including decriminalizing border crossings. Ry do you what could alienate the very voters the democrats need to attract to win back the white house . Alaina there is a b spectrum of people who do think that the crossing of the border should be decriminalized. But ere are others who belie that that would pretty much open the floodgates, d that seems to be Vice President joe bidens posion, that it is still criminal to cross the border illegally, but it is important to have humane asylum policies in place. I think that the majority, the bulk of voters, frankly, are on that page. They may not be in favor of decriminalizing border crossing, but having comprehensive and humane immigration policies in place. Laura alaina beverly, thank you so much for joining us. Alainamy pleasure. Laura you are watching bbc world news america. N still to comenights program, how the internet is changing the english language at a rapid pace. We sak to the woman tracking the transformation. In the u. K. , a mobile app is speeding up the detention of what could be a fatal kidney condition inpatients. Staff discovered the technology as a potential lifesaver, providing diagnosis in minutes. Poer whether it is the pager or fax machine, there is no shortage of Old Technology across nhs. But are we on the verge of a big leap forward . One hospital says it is a potential lifesaver. This is the kidney function we were talking about. Reporter he is being treated for Different Health conditions, and a specialist at the hospital is able to show him the results of blood test on her mobile. She is on the lookout for acute kidney injury, most often found in older patients. Warning signs from blood tests can take hours to come back, but she will get an alert on her phone in 15 minutes if there is any cause for concern. Le health care is mond realtime, and this is the first device that is enabling you to see results in mobile realtime way. Reporter csulteds involved in the project which has been independently and sussed say it saves money on treatment. Potentially it is lifesang. We need to gather a lot more atformation about this technology and loot over a longer time frame, but it is cert patients are very unwell, information comes to theorrect team quickly, and we cant put measures in place to make that tient safe we can put es in place to make that patient safe. Reporter the collaboration was criticized by the information commissioner over the use of patient data. The Commission Said the hospital had completed all thes. Equired acti hope is that in the fastpaced rld of a modern hospital, irving nurses and doctors information at tingertips can make a big difference in the way patients are diagnosed and treated. Laura today President Trump slapped even more tariffs on china. From september 1, a new 10 l be levied on 300 billion worth of chinese imports. It comes after the latest round of trade talks between the u. S. And china this week made little progress. This is what the president had to say about todays announcement. Pres. Trump for many years china has been taking money t by the hundreds of millions of dollars a year. We have rebuilt china, so now it is time wend changed it ar if they dont want to trade with usul anymore, that be fine with me. Laura here in the u. S. , the are fears that tariffs will force up prices and hurt the least well off famil Chris Buckler reports from the state of maryland. Chris right across rural americ there are towns where people are struggling to put food on their tables and and families who have no choice but to put their faith in the goodwill of neighbors and strangers. That one. Yes, fresh bread chris this is a food bank in westn maryland. W many come here rely on what is handed out to feed not just themselves se bec the granted stay with us most of the time. Granted stay with us most of the time. Ou want to be able to give them breakfast, lunch, and dinner. When you cant and the child is telling you they are still hungry, at hurts, that hurts a lot. That is the part that makes me cry, that i cant give to them. I have done and as a single parent, ive done without so that my kids would have. Its just hard. Its just hard. They are making it harder. Chris americas economy is doing well. That is not always obvious in places like smithsburg. A recent report warned that they should expect to pay another 800 a year on everyday items because of tariffs on prodhits from c, and even more if they are extended to goods from mexico. President trump has repeatedlyme clthat it is the countries who will pay for these import taxes, but that is simply not ue. Members of his administration are being forced to admit that wit is American Companies will pay the tariffs, and they are likely to pass the cost on to their coumers. This is just one of the warehouses for the Maryland Food bank. Itsize gives a sense of the need. While millions g help through the food stamp progr, snap, the Trump Administration is looking at changing thway poverty is measured, which would reduce access to the support. That small change affects thousands of families, thousands of individuals and families who are no longer going to be eligible for some assistance and have to find some other way to feed their families. Chris as it is, in the state of maryland alone, there are said to be more than 650,000 people dont know where their next nutritious meal is coming from. Most of our clients are a paycheck away from going under or a disaster hitting their family. S the needeat. Chris the danger for mr. Trump is that his polies and trade wars abroad could affect fortunes at home after american e home. Giv some love. Appreciate everything. God bless you. Chris Chris Buckler, bbc news. Laura how tariffs can be a hidden tax on the very poorest, and more are coming on september 1. Our language is constantly changing, and the internet is pushing the transformation. Conversations we have online are becoming mainstream,nd so are is the shorthand we use. 20 years ago, who could have foreseen we would all be lolg . In her new book because in a ternet, an author and nglinguist has been trac these changes, and she spoke to me earlier. Thank you for joining us. What is the key difference between the old languath rules annew internet rules . One of the things i think is interesting about the internet is it gives us this explosion of writing by ordinary people that is so mundane and so beautiful, that lets us write t we have been talking and not have these editorial rules that are imposed from on high but rules when you have people interacting with each other. Laura but there is confusion, as you point out in the book, over how different generations read internet language. Is lol an example of that . Exactly. Lol started out ughing out loud and turned into might send someone lol even if you did not laugh out loud acbecause you want towledge that they said something funny. This is common across generations. But there are additional uses of lol that are iric, sarcastic, acknowledging that something is not intended seriously, which sometimes has more differences crossgenerationally. Saying Something Like i hate you lol, it means im joking about hating you, this is teasing. Laura ok, i make my three teenage boys use capital letters and apostrophes when they text me, but should i just relax and embrace the new language . One of the thin we can associate with formalriting can come across as brusque, passive aggressive. E use of a period, full stop, at the end of every text can come across as passive aggressive, especially in a positive context. Laura you also point out that you can convey incoherent emotion effectively through internet language. What is a good example . Gretchen one of my examples is the key smash, where you mash your hands against the keyboard in order to convey that you are so excited or so overwhelmed or so angry that you do not even want to type with words. What is really interesting is that even key smash has these sorts of patterns to it. People type key smash in ways that are socially legible to each other. I did a survey asking when youey typemash, do you ever go back and retype and adjust a few letters to make it seem like a better key smash . E most peold me they had. Even when you think you are one of a Million Monkeys at a million typewriters, you are still paying attention t w patternst we socially expect of each other. Laura should we be excited that language is evolving in a new and democric way on the internet . Hogretchen absolutely, wed be excited. It is really exciting that so many people have access to potentially a larger audience than they might have had before. You do not need the approval ofo an authority ihave something that is worth saying. You can get it out there. A thank you so much for being with us. Gretchen thank you so much for having me. Laura the new language is here, is tit or not, and it to embrace the key smash and not mourn the comma. You ca days news on our website.
