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: Muskegon resident Pamela Anderson said that after hearing about numerous cases, she started a Facebook group about cancer deaths among people who live or have lived near the Butterworth landfill site in Grand Rapids. They plan to bring up the issue at a city commission meeting this week, the Grand Rapids Press reported . The group recently met with Kent County Health Department epidemiologist Brian Hartl, who advised them to collect more information on cancer rates in the area. "If there are rare forms of cancer, or cancers we're seeing affect a young population, it might trigger further investigation," Hartl said. But he cautioned that cancer is difficult to study, and that it can take years and multiple triggers to emerge. "Especially in small areas like a neighborhood or a block, it makes it challenging to connect it to environmental exposure," Hartl said. "Most cancers are due to lifestyle choices, not environmental factors." The Environmental Protection Agency estimates that theoretical cancer and health risks from the landfill exist, but that they're limited to regular direct contact with the waste over several decades. The agency conducted a site cleanup in 1999, and removed material contaminated with polychlorinated biphenyl and chromium. The EPA said there is no current exposure at the site. "A lot of those kids in the '60s and '70s used to play in the dump," said Shane Smith, who grew up down the street from Anderson in the Indiana Avenue neighborhood. "It was just starting to alarm to us, because my dad's entire generation passed away from cancer." Anderson said she's having the soil tested for contaminants at a home in the same neighborhood. ___ Information from: The Grand Rapids Press, http://www.mlive.com/grand-rapids Claim: Residents investigate cancer rates near Michigan landfill.
answer:
A group of residents is investigating cancer rates in a western Michigan neighborhood that's near a contaminated landfill classified as a Superfund site.

question:
Paragraph: This story not only mentions the cost for this drug but also for other treatments for osteoporosis as well. The story did a great job of distinguishing among various fracture types and reporting both relative and absolute risk reduction for vertebra fracture. But then it was disappointing that the risk reduction for hip fractures and that of wrist, leg, or shoulder were reported as only relative risk reduction. Since the story characterized hip fractures as 'devastating', it should have provided the reader with some sense of how frequently they occur rather than simply indicating how often they result in a person entering a nursing home or dying within 5 years of having one. Nonethless, because of the elements that were well done, we'll give the story the benefit of the doubt on this criterion. The story gave a rather complete listing of the potential harms associated with the use of this drug, including specific mention of those problems that are unique to this drug as compared with other medications used to manage bone loss. Although the list was complete, the story did not indicate the frequency with which these harms occurred. Nonethless, we'll give the story the benefit of the doubt on this criterion. The story provided information about the clinical trial it described, including the number of people studied, the length of time they were studied and the impact on various types of fractures. The story only indicated lifetime risks of fracture (i.e. 1 out of every 2 women over the age of 50) and that 25% of people die within 5 years of breaking a hip without providing some context for these concerns. The 5 year risk of fracture for a woman aged 55 is not the same as that for a woman aged 75; similarly, there are other factors compounding the statistic about death following hip fracture. Since the drug is marketed as being for women who are postmenopausal, rather than simply parroting these seemingly alarming pieces of information, the story should have provided more context for these statistics. This was one weak point in an overall strong story but an important nuance that should not be overlooked. Comments about this drug and its potential utility from two clinicians noted as not having industry ties to this or other osteoporosis drugs were included in this story. This story compared the benefits, harms and costs for the new drug, with those treatments already on the market. The story opens with a statement about this drug's approval by the FDA. The story provided a useful explanation of how this medication differed from the other treatments available for osteoporosis. Does not appear to rely exclusively on a news release. Claim: The pros and cons of Prolia, Amgen's new osteoporosis drug
answer:
The story detailed what is known about the impact of this drug on various types of bone fractures associated with osteoporosis, how its mode of action is someone different than other osteoporosis treatments, its administration and how the costs compare with other treatments. The one shortcoming of the story was that it had elements of disease-mongering, as explained below. The gestalt about osteoporosis is that women should live in fear of bone breaks. While the story provided very good information about this new treatment, it did not provide much context about the problem. And its inconsistent use of relative vs. absolute risk/benefit data didn't help.
