As someone who once criticized President Barack Obama for offering public timelines on American military engagement overseas, US President Donald Trump may have backed himself into a corner following his own promise to respond, and respond harshly, to the deadly chemical attacks in Syria.Last week he declared he wanted to withdraw US troops from Syria as soon as possible. But the suspected use of chemical weapons in Syria over the weekend may force him to reevaluate the US mission in that country.Vowing on Monday to come to a decision "over the next 24 to 48 hours" on how to make Syria pay a "big price," Trump's White House now appears to be scrambling to match its policy to his words.Trump tweeted Wednesday that missiles "are coming" in response to a threat from Russia to shoot down missiles coming into Syria.  836

As New Haven, Connecticut, Fire Chief John Alston Jr. spoke to reporters about a spate of drug overdoses on Wednesday, he heard shouting coming from behind him."We're getting another call of a person," Alston said.He quickly helped coordinate the response, and then returned to the microphone.That scene came on the same day that as many as 40 people in the area of New Haven Green were believed to have overdosed on some form of K2 that may have been laced with opioids, according to New Haven police spokesman Officer David Hartman.New Haven Green is a large park and recreation area in the city's downtown.The patients included people of various ages and demographics, Alston said."It's a nationwide problem. Let's address it that way," he said. "It's a nationwide problem that people are self-medicating for several different reasons, and every agency -- police, fire, medical hospitals -- all are strained at this time. This is a problem that's not going away."New Haven police said one person is in custody.Director of Emergency Operations for New Haven Rick Fontana said the patients had symptoms of increased heart rates, decreased respiratory rates and a lot of vomiting. Some people were unconscious, others were semi-conscious.No one has died, but two individuals are considered to be in serious, life-threatening condition. Some individuals who were released from the hospital needed to be treated a second time for an additional apparent overdose, Fontana said.K2 is a synthetic cannabinoid related to marijuana that is frequently laced with other drugs, said Dr. Sandy Bogucki of the Yale School of Public Health.In two cases, Narcan was not effective in the field, but a high dose of Narcan at the hospital was effective in combating the overdose effects. Because of that, authorities believe there was some form of opioid or synthetic fentanyl involved in the substance.The response from emergency responders has been "tremendous," Fontana said.He said authorities have been treating and sometimes transporting six or seven people at one time and the actions of first responders have been "lifesaving." 2131

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

As the nation debates on whether to reopen schools this fall, President Donald Trump said schools should “100%” be open this fall, despite concerns from educator unions and others over the spread of the coronavirus.During his coronavirus news conference on Wednesday, Trump was asked whether he planned on sending his son and grandchildren back to school this fall.“Yes, I am comfortable with that,” Trump said.“I would like to see the schools open. Open 100% and we will do it safely, we will do carefully but when you look at the statistics -- I just read having to do with children and safety ---- they are very impressive. They have very strong immune systems,” Trump added.Trump said that it is his belief that children are less likely to spread the virus. But research thus far has not been conclusive to back Trump’s claims.A study released from South Korea and published by the CDC found that while children under age 9 were less likely to spread the virus, youth ages 10 through 19 were just as likely as adults of spreading the virus.The study also found that closing schools in several Chinese cities, including Wuhan, showed that school closure and social distancing significantly reduced the rate of COVID-19 among contacts of school-aged children. “The role of household transmission of SARS-CoV-2 amid reopening of schools and loosening of social distancing underscores the need for a time-sensitive epidemiologic study to guide public health policy,” the researchers wrote.The American Federation of Teachers this week pointed toward a three-point plan that the US should implement for reopening schools.“Our plan details three conditions essential for schools to reopen,” wrote Randi Weingarten, president of the American Federation of Teachers. “First, the average daily community infection rate among those tested for the coronavirus must be very low. (New York Gov. Andrew Cuomo has required the rate not to exceed 5 percent for at least 14 days.) Second, schools must employ public health protocols, including 6-feet social distancing, masks, deep cleaning and handwashing stations. Third, adequate resources must be available to enact these safeguards, including funding for additional nurses, guidance counselors and teachers to reduce class size.”Weingarten said that Trump has politicized reopening schools, and she called on Congress to approve giving schools additional funding to reopen. Weingarten projects that it would take 6 billion nationwide to provide essential services for schools."Expenses have increased because of the fight against coronavirus," she said. "They not only need funds to provide essential services, the average school will need an additional .2 million, or ,300 per student, to open its doors safely." 2770

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
