As the coronavirus pandemic continues, doctors are learning more about the damage having Covid-19 can do to the body. Two separate studies published recently indicate the coronavirus can harm other organs in the body, including the heart.One of the studies looked at 100 patients in Germany who recently recovered from Covid-19 and found 60 percent of participants had inflammation in the heart. The study used MRI scans to monitor the inflammation, and was published in JAMA Cardiology.The majority of the patients in this study, 67 of them, recovered from the coronavirus at home with severity ranging from asymptomatic to moderate. It compared the MRIs of coronavirus survivors to scans from healthy volunteers.The data showed there was some sort of heart involvement in those who had coronavirus, whether or not they had preexisting conditions or any heart-related symptoms during recovery.“Our findings reveal that significant cardiac involvement occurs independently of the severity of original presentation and persists beyond the period of acute presentation, with no significant trend toward reduction of imaging or serological findings during the recovery period. Our findings may provide an indication of potentially considerable burden of inflammatory disease in large and growing parts of the population and urgently require confirmation in a larger cohort,” the researchers noted in conclusion.A second study, also published in JAMA Cardiology, found coronavirus could be found in the heart tissue of patients who died.The study looked at data from 39 autopsy cases in Germany in early April. The patients were aged 78 to 89, had tested positive for Covid-19 and there were results of heart tissue analysis in their autopsies.In 16 of the 39 cases, there was a large “virus load” of coronavirus found in the heart tissue, another eight had a coronavirus presence in the tissue.The sample of autopsy cases was small and the "elderly age of the patients might have influenced the results," the researchers wrote. More research is needed whether similar findings would emerge among a younger group of patients."Taken together the studies support that SARS-CoV-2 does not have to cause clinical myocarditis in order to find the virus in large numbers and the inflammatory response in myocardial tissue. In other words, one can have no or mild symptoms of heart involvement in order to actually cause damage," said Dr. Dave Montgomery, who was not involved in the studies, in a statement to CNN.Dr. Clyde Yancy of Northwestern University Feinberg School of Medicine and Dr. Gregg Fonarow of the University of California, Los Angeles, co-authored an editorial that accompanied the two new studies in the journal JAMA Cardiology called ‘Coronavirus Disease 2019 (COVID-19) and the Heart—Is Heart Failure the Next Chapter?”“We see the plot thickening and we are inclined to raise a new and very evident concern that cardiomyopathy and heart failure related to COVID-19 may potentially evolve as the natural history of this infection becomes clearer,” they write. 3076

AURORA, Colo. — Amid renewed calls for justice, Colorado Gov. Jared Polis announced Wednesday that he is looking into what his office can do to respond to the death of Elijah McClain, a 23-year-old Black man who died following an interaction with Aurora police last August.“I am hearing from many Coloradans who have expressed concerns with the investigation of Elijah McClain’s death. As a result, I have instructed my legal council [sic] to examine what the state can do and we are assessing next steps,” Polis said in a tweet Wednesday afternoon.Over the past couple of weeks, interest in the case has grown both locally and nationally. People from Colorado State Rep. Leslie Herod to U.S. Sen. Elizabeth Warren, Ellen Degeneres and Martin Luther King Jr.’s daughter, Bernice King, have made calls for justice in the case and a renewed investigation into what happened that night and if officers should face punishment. A Change.org petition calling for justice has been signed more than 2.3 million times as of Wednesday afternoon.At the same time, pressure from the Aurora City Council to complete a search for a new independent investigator into McClain’s death by next month is mounting.A letter from Council Member Curtis Gardner to Aurora’s City Manager Jim Twombly urged Twombly to have the recommendations for a new third-party investigator ready to present by July 16, the date of Aurora’s Public Safety Policy Committee’s next meeting.As @AuroraGov's Public Safety policy committee, we sent the following letter to the City Manager requesting his recommendations for individuals to complete the independent investigation into the death of #ElijahMcClain at our July 16 meeting.@AllisonHiltz @LawsonForAurora pic.twitter.com/10ri9YoLn3— Curtis Gardner (@CurtisForAurora) June 24, 2020 Mayor Mike Coffman on Wednesday afternoon called for a special City Council meeting on July 6 to vote on whether or not to authorize an independent investigation in the case, with a second vote on who will conduct the investigation. The call came after the letter from the Public Safety, Court, and Civil Service Policy Committee. A release from the city said that the committee will bring the proposal forward to the full council at the July 6 meeting."We need to bring closure to this tragic incident by making sure every aspect of it is thoroughly investigated," Coffman said in a statement."Trust is already eroded—delaying action will only cause further strain in our community," said Allison Hiltz, the chair of the Public Safety, Court, and Civil Service Policy Committee.The independent investigation has been fraught with controversy since many council members felt the original outside probe, led by a Connecticut-based attorney with ties to law enforcement, was not independent enough. That contract was terminated June 10 and Mayor Mike Coffman said in a tweet that “another individual will be selected by the Mayor and the City Council.”Calls for an independent and external review in McClain’s August 2019 death have been ongoing since it happened, and the officers involved in his death did not face criminal charges and were found not to have violated department policies. The city has since changed department policies directly in the wake of McClain's death after calls for further investigation.McClain suffered a heart attack on the way to a hospital after the Aug. 24 incident, which happened in the 1900 block of Billings Street. Officers had responded to a call about a suspicious man wearing a ski mask and waving his arms. When they arrived, they contacted McClain, who they claimed resisted when the officers tried to detain him, police said.A struggle ensued, and a responding officer requested that a paramedic give McClain a dose of ketamine "due to the level of physical force applied while restraining the subject and his agitated mental state," officials said.But in the department's review of the incident earlier this year, the board found that the officers "had a lawful reason to contact Mr. McClain."The board also found that the force applied by officers — which included a carotid control hold — during the incident was "within policy and consistent with training."The carotid hold has since been banned by the department.The Adams County Coroner conducted the autopsy on McClain and ruled that the manner of his death was "undetermined," saying it could not determine whether his death was an accident, due to natural causes or a homicide.District Attorney Dave Young said Wednesday his office received more than 1,700 voicemails on Tuesday alone about the McClain case.He says he has to make a decision based on evidence and that a jury would find compelling beyond a reasonable doubt.“Understand that my role is limited to determine whether or not a criminal violation occurred. I am not indicating that the actions of the police department were appropriate. That's the role of the Aurora Police Department,” Young said.KMGH confirmed Wednesday the officers involved are all still currently employed by the Aurora Police Department.Young says the attacks have gotten personal and are overwhelming his office from doing their job of serving victims of crime.He encourages those sending emails to read his decision. Young said if new evidence comes to light in the case, he would reconsider.“The emails, the voicemails, the attacks on Facebook — not only to me, but my family — is not evidence that can be used in a court,” Young said.KMGH's Robert Garrison, Jessica Porter and Blair Miller contributed to this report. 5563

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

Astronomers looking at the atmosphere in neighboring Venus see something that might just be a sign of life.In a study published Monday, researchers from Cardiff University, MIT and elsewhere say they found the chemical signature of a noxious gas called phosphine.On Earth, phosphine is associated with life. It's found at the bottom of ponds, in badger guts and in penguin guano.Venus’ phosphine was observed in a narrow, temperate band within the planet’s atmospheres, where temperatures range from 30 to 200 degrees Fahrenheit. Scientists have speculated that if life exists on Venus, this layer of the atmosphere, or cloud deck, is likely the only place where it would survive, according to MIT.“This phosphine signal is perfectly positioned where others have conjectured the area could be habitable,” said the study’s co-author and EAPS Research Scientist Janusz Petkowski.Astronomers tried to figure out other, non-biological ways it could be produced and came up empty.“It’s very hard to prove a negative,” said Clara Sousa-Silva, research scientist in MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS). “Now, astronomers will think of all the ways to justify phosphine without life, and I welcome that. Please do, because we are at the end of our possibilities to show abiotic processes that can make phosphine.”Outside experts — and the study authors themselves — say the research is tantalizing but not yet convincing. 1454
