There's no discussion of cost, even to mention that statins are relatively inexpensive these days and are mostly generically available. To its credit, the article does mention the cost of a calcium scan. We learn that "anywhere from 50 to 200 healthy people need to take a statin daily to prevent a single heart attack for five years." That's helpful information. It also notes that the observed benefit is less for older patients. The story could have added that even those numbers might disputed by some experts who perceive no meaningful benefit. For example, one review found being on a statin does not help people with low risk for heart disease live longer. The story does a service by highlighting the harms of statins. It explains: "The most common side effect of these drugs is muscle pain, which usually goes away if patients stop taking the medicines. People taking statins are also at a higher risk of developing diabetes, which is harder to reverse." It also mentions the potential for overtreatment with the use of coronary calcium scans. However, we wish it had included absolute numbers. The story says harms are "uncommon," but provides no data to back that up. Rates of adverse effects with statins have been measured at 1 to 10%, which makes them "common" in the definition of the European Medicines Agency. Also noteworthy is that some contend that adverse effects of statins have not been reliably reported. The story doesn't explain the quality of the study, or of studies on which current guidelines are based. We don't explicitly learn that this is a modelling study. In other words, this study consisted mostly of reinterpretations of math, not re-evaluations of real-life patients. The researchers said they were unable to obtain enough data on all possible harms and age-specific data on some harm outcomes, "so the risk thresholds we determined may still be too low." There is no disease-mongering here. This story includes sources that weren't involved in the study. The study's authors reported no conflicts of interest. The story could have acknowledged the influence of pharmaceutical companies in creating guidelines for statin use. The alternative of not taking a statin was the key message here, and that's laudable. However, we have a couple of concerns. First, we learn that "some statins were more effective than others, with atorvastatin (the generic name for Lipitor) being the best of the bunch." However, the story doesn't explain on what basis some statins are "more effective." In fact, some statins may be more effective at lower cholesterol, but the study found that no statin rises above others when it comes to the outcomes that counts most to patients reducing cardiovascular deaths. Also, the story doesn't mention lifestyle interventions diet and exercise. The story makes it clear that statins are widely prescribed. The story states this an attempt to better weigh the benefits and harms of statin use. There was a good range of interviewees with no reliance on a news release

The advisory is for people using the waters for recreation. The advisory area is from the McAlpine Dam near Louisville to the Greenup Dam near Greenup in northeastern Kentucky. State officials also issued an advisory for Briggs Lake near Russellville. The advisory means algal toxins have been found at various locations along the water. Swimming, wading, and other water activities are not recommended during the advisory. State officials say ingested water may increase the risk of gastrointestinal symptoms such as stomach pain, nausea, vomiting and diarrhea. It can also cause skin irritation.

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.
