At least 105 people are dead after an earthquake rocked the Indonesian island of Lombok over the weekend, state media reported Tuesday.Another 236 people have been injured in the quake, according to the government's disaster management spokesman Sutopo Purwo Nugroho, who told the Antara News Agency that the casualty numbers could rise as the search continued for survivors.More than 20,000 people have been displaced since the 6.9-magnitude quake struck Lombok, a popular tourist destination, on Sunday night.The epicenter of the earthquake was in northern Lombok, a more residential and less developed part of the island. Most of the tourist resorts are located on the southern side of the island.Most of those killed were struck by falling debris from collapsed buildings, according to Nugroho. Among the many buildings destroyed on Lombok were two homes which housed around 80 underprivileged children. 915

As states across the country grapple with an increase in coronavirus cases and a huge demand for tests, many businesses are looking for other ways to get more mileage out of their supply chain.Like with anything else, supply and demand is a constant struggle. In this unprecedented era, the demand for things like coronavirus tests is so large that public health departments don't have a choice but to figure out ways to make our supplies last. Several states are examining pooled testing. California's Public Health Department says it's to "better leverage testing resources."Pooling is something that blood banks have used for decades to keep their blood supply safe. Dr. Claudia Cohn is the Chief Medical Officer of the AABB, formerly known as the American Association of Blood Banks.“If you have 100 people that need to be tested and if you test each of them, you’ll do 100 tests. If you find that your test is sensitive enough that you can pool together 20 samples at the same time, instead of having 100 tests, you can have five pools of 20,” Dr. Cohn said.Now, if one of those five pools is positive, then Dr. Cohn says, "You’ll need to break it out and test each of those separately. So, let’s say you have one positive person in a pool of 100 people, you either do 100 tests and find one positive or you do five pools of 20, four of those pools will be negative, so you’ve done 4 pools and covered 80 people."The test works by taking a tiny sample from each person who was tested.“When you take a swab from everyone’s nose, you isolate the DNA from that swab,” Dr. Cohn said about the PCR test, which is generally a nose swab. “It’s not a lot, it’s a small amount but it’s enough. Because these tests are very, very sensitive.”Those tests are so sensitive, and they have to be, that pooling can really only work if the test can handle, as in detect, multiple samples at once. The FDA mandates that.“The FDA is quite demanding as they should be in terms of making sure tests work well and are safe,” Dr. Cohn said.And Dr. Cohn says, pooling wouldn't work in an area where there's a large outbreak, which means a large number of people would test positive regardless of pooling. In the blood world, this strategy has been perfected.“You are taking 100 samples and taking a drop from each sample and putting it together,” Dr. Cohn said. “You are testing every single person who comes through. In the blood world safety is before everything."Blood banks test for HIV, Hepatitis C and B and well as COVID-19 antibodies, according to the American Red Cross. And, as this pandemic moves through our communities, Dr. Cohn says our blood supply needs to remain strong.“After that initial spike, it went down again and that was okay because elective surgery had been canceled, so the demand for blood had gone down as well so for a while we were at a good balance of demand and supply. But then elective surgeries opened up and hospitals went back to full service and we’re in a shortage again,” Dr. Cohn said. 3017

AUSTIN, Texas — For Brett Hagler, the co-founder of non-profit New Story, building homes for people without adequate shelter is nothing new."We get a large piece of land and work with families that have been living in shacks or tents without shelter and design a totally new community with the families.”Approximately one billion of the world’s population is without proper shelter.To make a dent in that he says, they have to think outside the mold.“We believe traditional ways cannot get us there.”So for New Story’s next endeavor—adding more communities to the land they’ve already acquired in El Salvador—they teamed up with a brand new startup.That’s where Evan Loomis comes in. He’s the co-founder of Austin, Texas-based Icon, a company focused on new technologies for building homes.Their first big debut came at this year’s South by Southwest festival in their hometown.“This is a gigantic robot,” Loomis says, gesturing toward a large steel frame on wheels. “[It] really does some amazing things. Down to the millimeter it knows exactly where to place building materials.”In this case that material is a proprietary mixture of concrete, that pours out of a nozzle on the underside of the metalwork. And the machine moves along a computerized map to create a house.“This is basically the first permitted 3D printed house in the United States,” he said.“We have to invest in [research and design],” Hagler said. “[We asked ourselves] ‘how do we get a breakthrough in cost, speed, and quality?’ And that’s how we landed upon 3D-home printing. The excitement in the air is palpable as they walk us through and around this modest home built up of about 100 one-inch thick concrete layers.“It’s stronger than regular cinder block,” Hagler said. It also comes at a fraction of the cost of a regular house. This model had a price tag of about ,000 but they hope to get the price down to ,000.“We can build in a fraction of the time [compared to traditional construction methods], and it can have a higher quality, strength, and sustainability for the environment."It was 'printed' in just 48 hours. Eventually, they say it will be done in just a half day. It’s a small but open floor plan — with no physical doors — and rooms are separated by partial walls made up of the printed concrete.They say they’ll easily be able to customize different designs.The prototype home can fit a family of four or five.“If you’re coming from a tent or shack and you move into this,” Hagler said, “it’s a significant life-changing difference.”One of the things they’re most excited about with their upcoming 3D-homes project in El Salvador is the fact that they’re introducing groundbreaking technology to the people who usually see tech advances last.“We are actually bringing them the future -- which is robotic construction of housing — first,” Hagler said. “And they’re really excited about that.”They say they plan to begin construction in El Salvador before the end of the year with the hopes of finishing their first community of homes by early 2019. There could one day be plans for 3D printed homes in some of the poorest areas of the United States as well, Loomis said, but he has his eye set on possibly expanding to terrain that’s literally out of this world.“It could be a really great solution for making space habitation a lot more achievable,” Loomis said. “We hit a nerve with this technology, and we are going to hit the gas hard and try to take it to everybody now.” 3528

Asked whether President Donald Trump had ever used the N-word, White House press secretary Sarah Sanders would not definitively say, instead referring reporters to a tweet."The President addressed that question directly," she said, adding, "I've never heard him use that term or anything similar."The question comes as former aide Omarosa Manigault Newman has claimed there's a tape of Trump using the racial epithet on the set of his NBC reality show "The Apprentice" -- though there is no evidence such a tape exists.Trump tweeted Monday night: "I don't have that word in my vocabulary, and never have."Pressed specifically on whether any recording of the President using the racial epithet exists, Sanders said: "I can't guarantee anything, but I can tell you that the President addressed this question directly."She maintained that Trump is someone who is "fighting for all Americans," and that his policies are helpful "particularly for African-Americans," citing African-American unemployment statistics.Sanders also claimed Tuesday that Trump's description of his former aide as a "dog" had "nothing to do with race and everything to do with the President calling out someone's lack of integrity."The "dog" comment was one of many insults the President has used to describe prominent African-Americans, but Sanders insisted Trump insults people of other races as well."The President's an equal opportunity person that calls things like he sees it," she said. "He fights fire with fire." 1501

ATLANTA, Ga. – The U.S. Marshals Service says it found 39 missing children in Georgia this month during an investigation called “Operation Not Forgotten.”The two-week operation in Atlanta and Macon resulted in the rescue of 26 children, the safe location of 13 kids and the arrest of nine “criminal associates,” the USMS announced Thursday.Additionally, investigators say they cleared 26 arrest warrants and filed additional charges for alleged crimes related to sex trafficking, parental kidnapping, registered sex offender violations, drugs and weapons possession, and custodial interference.The USMS says the missing children were considered to be some of the most at-risk and challenging recovery cases in the area, based on indications of high-risk factors such as victimization of child sex trafficking, child exploitation, sexual abuse, physical abuse, and medical or mental health conditions.Since its partnership with the National Center for Missing and Exploited Children, the USMS says it has recovered more than 1,800 missing children.“When we track down fugitives, it’s a good feeling to know that we're putting the bad guy behind bars. But that sense of accomplishment is nothing compared to finding a missing child," said Darby Kirby, Chief of the Missing Child Unit. “It's hard to put into words what we feel when we rescue a missing child, but I can tell you that this operation has impacted every single one of us out here. We are working to protect them and get them the help they need.”This month’s operation was the culmination of several months of planning and coordination between the USMS, NCMEC, Georgia Bureau of Investigation, Georgia Office of the Attorney General, Georgia Department of Family and Children Services, Georgia Department of Juvenile Justice, the Federal Bureau of Investigation and Children’s Healthcare of Atlanta.“The U.S. Marshals Service is fully committed to assisting federal, state, and local agencies with locating and recovering endangered missing children, in addition to their primary fugitive apprehension mission,” said Director of the Marshals Service Donald Washington. “The message to missing children and their families is that we will never stop looking for you.” 2233
