question:
Paragraph: A photograph popped up on social media in May 2015, described as a picture of a blood clot removed from an 80-year-old patient after he presented with a 2-day-long nosebleed. According to the accompanying text, the patient coded shortly after arrival at an emergency room, and a blood clot that went “from his nose down his airway and into his lungs” was removed via intubation:  80 yr old male with nose bleed for 2 days. Refused to go to ER. Wife finally talked husband to go to ER. He coded shortly after arriving. Medical doctor went to do intubation and found this. Pulled it out in one piece. It a blood clot that goes from his nose down his airway and into his lungs. It an amazingly beautiful blood clot. The photograph was shared by Kevin Kimberlin, an EMT who told us that the patient was treated at a hospital he transports to and that he picture was taken by a friend of his who worked on the patient. In November 2018, the New England Journal of Medicine website posted a similar photograph of “an intact cast of the right bronchial tree” that was “spontaneously expectorated” by a patient “during an extreme bout of coughing”: Claim: A photograph shows a large blood clot removed from a patient's lung.
answer:
A photograph purportedly captured a huge blood clot removed from a patient's lung.


question:
Paragraph: Analysis of powdered samples drilled out from inside an ancient and once water-soaked rock at the rover’s Gale Crater landing site show clays, sulfates and other minerals that are all key to life, scientists told reporters at NASA headquarters in Washington and on a conference call on Tuesday. The water that once flowed through the area, known as Yellowknife Bay, was likely drinkable, said Curiosity’s lead scientist John Grotzinger, who is with the California Institute of Technology. The analysis stopped short of a confirmation of organics, which are key to most Earth-like life. But with 17 months left in the rover’s primary mission, scientists said they expect to delve further into that question. Science operations currently are suspended because of a computer glitch, which is expected to be resolved this week. Whether or not Mars has or ever had life, it should have at one time at least had organic compounds delivered to its surface by organic-rich comets and asteroids. Finding places where the organics could have been preserved, however, is a much trickier prospect than finding the environmental niches and chemistry needed to support life, scientists said. In May, following a one-month interruption of radio communications caused by the positions of Earth and Mars, scientists plan to drill a second hole into the Gale Crater rock to look for organic compounds. “If there was organic material there, it could have been preserved,” said David Blake, principal investigator for Curiosity’s Chemistry and Mineralogy, or CheMin, experiment. A lack of organics, however, would not rule out the Yellowknife Bay site as suitable for life, scientists added. “You don’t have to have carbon present in a geological environment that’s habitable in order to have microbial metabolism occur,” Grotzinger said. Some micro-organisms on Earth, for example, can feed on inorganic compounds, such as what are found inside rocks. “There does need to be a source of carbon somewhere, but if it’s just CO2 (carbon dioxide), you can have chemoautotrophic organisms that literally feed on rocks and they will metabolize and generate organic compounds based on that carbon,” Grotzinger said. Analysis shows the Gale Crater rock contains carbon dioxide, in addition to hydrogen, oxygen, phosphorus, sulfur and nitrogen. Carbon dioxide provides a key ingredient in the building blocks for life, all of which have now been found in the Mars rock sample, Grotzinger said. The $2.5 billion, nuclear-powered Curiosity rover landed inside the giant Gale Crater impact basin, located near the Martian equator, on August 6 for a two-year mission. Scientists were drawn to the area because of a three-mile (5-km) mountain of sediment, called Mount Sharp, rising from the crater floor. But shortly after the rover’s landing, the team decided to first explore the Yellowknife Bay area, located in the opposite direction from Mount Sharp. Observations from Mars orbiters showed three different types of terrain coming together in Yellowknife Bay, plus a low elevation, all hints that water could have once flowed and pooled on the surface. That hunch was verified with the first chemical analysis of material drilled out from inside what appears to be a slab of bedrock, named John Klein, after a mission manager who died in 2011. Scientists don’t know the rock’s age, nor how it formed. They suspect, however, that the John Klein rock is at least 3 billion years old and that it spent enough time in non-acidic and not-too-salty water for various telltale clays and minerals to form. “This rock, quite frankly, looks like a typical thing that we would get on Earth,” Grotzinger said. “The key thing here is this is an environment that microbes could have lived in and maybe even prospered in.”  The habitable conditions in Yellowknife Bay appear to roughly coincide within a couple of hundred million years of the first evidence for life on Earth. “On Earth, finding organics in very, very ancient rocks is a difficult proposition,” said Paul Mahaffy, principal investigator for Curiosity’s Sample Analysis at Mars, or SAM, instrument. Finding organics on Mars may be even more challenging. Without much protection from an atmosphere, ultraviolet and cosmic radiation can destroy organics. Mars also apparently is covered with chemicals, known as perchlorates, that consume organics. “The search for organic carbon is an issue for this mission and you want to do this as deliberately as possible. You don’t just want to wander around and try stuff out,” Grotzinger said. Knowing that Mars at least had the ingredients for life, however, makes the search for organics more viable. “This is not a simple problem, but I think the mission is up to it and we’re really excited to get started on that now,” Grotzinger said. Claim: Mars had the right stuff for life, scientists find.
answer:
Seven months after NASA’s rover Curiosity landed on Mars to assess if the planet most like Earth had the ingredients for life, scientists have their answer: Yes.


question:
Paragraph: Speaking at a White House coronavirus briefing, Trump said he would unveil a new advisory group next week that would focus on the process of economic opening. The president, who faced criticism for playing down the threat from the virus in its early stages, has chafed at the devastating economic impact of the strict social distancing measures his administration has recommended. The guidelines are set to stay in place through the end of April. The president will then have to decide whether to extend them or start encouraging people to go back to work and a more normal way of life. “I’m going to have to make a decision, and I ... hope to God that it’s the right decision,” Trump said. “It’s the biggest decision I’ve ever had to make.”  Trump said the facts would determine the next move, though he reiterated his desire to re-open the economy. Asked what metrics he would use to make his judgment, he pointed at his forehead: “The metrics right here, that’s my metrics.”  Trump suggested the number of new infections was flattening and the death toll would be lower than initial projections of more than 100,000. He said he would announce the members of the new advisory council possibly on Tuesday. Some state governors will be appointed. Trump said the aggressive social distancing and stay-at-home measures taken to combat the coronavirus were showing signs of success, and situations in hot spots such as New Orleans, Louisiana, and Detroit, Michigan, were stabilizing. U.S. deaths from the virus topped 18,100 on Friday, according to a Reuters tally. But administration officials cautioned it was still too early to ease restrictions, and said the faithful should not gather in churches on the Easter Sunday holiday. “We know it’s difficult in this time of year in particular to avoid gatherings of more than 10, but we’re grateful that so many churches, synagogues and places of worship have done just that,” Vice President Mike Pence said, urging worshipers “to continue to heed the guidelines.”  New U.S. government figures show coronavirus infections will spike during the summer if stay-at-home orders are lifted after 30 days as planned, according to projections first reported by the New York Times and confirmed by a Department of Homeland Security official. If shelter-in-place orders are lifted after 30 days, the death toll is estimated to reach 200,000, according to the projections, obtained from DHS and the Department of Health and Human Services. Trump said at the briefing that he and his advisers have not seen the new projections. Trump said he was getting fewer calls from governors urgently seeking equipment and help. “We’re in great shape with ventilators, we’re in great shape with protective clothing, we have additional planeloads coming in. But we’re not getting any calls from governors at this moment,” he said. Dr. Deborah Birx, the coordinator of the White House task force on the coronavirus, said the United States was starting to flatten the curve the way Italy did, with a lot of the success coming from progress in New York City. Officials have pointed to declining rates of coronavirus hospitalizations and need for intensive care in hard-hit New York as signs that social distancing measures are paying off. “But as encouraging as they are, we have not reached the peak. And so every day we need to continue to do what we did yesterday, and the week before and the week before that because that’s what in the end is going to take us across the peak and down the other side,” Birx said. Claim: Using his own 'metrics,' Trump says ending U.S. shutdown is biggest decision yet.
answer:

President Donald Trump said on Friday he faced his biggest decision yet with regard to when to re-open the U.S. economy from its coronavirus shutdown and pledged to listen to health experts when making that determination.
