PROBLEM: 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.

SOLUTION: 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.

PROBLEM: Paragraph: Children watch television in the living room of an apartment that is for sale for $4.5 million in New York in this January 13, 2011 file photo. REUTERS/Lucas Jackson This type of disguised advertising, including high exposure to sugary soft drinks on prime-time TV, is a major contributing factor to childhood obesity, according to the Yale University study released Tuesday. “It is a very subtle message that kids aren’t likely to get,” said Jennifer Harris, a co-author of the study and director of marketing initiatives at Yale’s Rudd Center for Food Policy and Obesity. The Yale study aimed to quantify how many product placements appear on prime-time TV and also determine how many of those that kids actually see. Researchers analyzed Nielsen media data from 2008 and found some 35,000 brand placements had appeared on prime-time television that year. Children tend to see about 14 traditional advertisements for food and beverages each day on television compared to one of these product placements, it said. But children don’t yet have the cognitive ability to understand that the popular soda, candy and snack brands they see on prime-time shows are a means of advertising. “It is even more difficult for younger children to understand this is advertising and that it is persuading them to do something that isn’t the best thing for them,” Harris said. Despite most major food companies pledging not to pay for unhealthy food ads in children’s programing, brand appearances in prime-time shows and sportscasts viewed by a wide audience, including kids, is exposing them to these products anyway, Harris said. Harris said Coca-Cola product placements on popular talent show American Idol was the most viewed brand. Children saw five times as many product placements as they did traditional, paid television commercials for Coca-Cola products. Roughly one-third of children in the United States are overweight or obese, said Harris. Drinking sugar-sweetened beverages puts kids at greater risk for obesity, but also long-term health problems like diabetes, heart disease and high blood pressure, she said. The study will appear in the September issue of the American Journal of Preventive Medicine. Claim: TV product placements termed junk food ad loophole.

SOLUTION: Companies that have pledged not to market unhealthy food and drinks directly to children may be turning to product placement on television shows instead of traditional ads to target youngsters, a new study showed.

PROBLEM: Paragraph: The charity’s board chair, Carrie Coghill, says the idea is for the award to be seen as similar to a Nobel Prize for women’s health. The Richard King Mellon Foundation is funding the effort. The group’s efforts are built around three goals. The 9-90 program focuses on identifying and curing illnesses originate while a person is in the womb, but which can last for 90 years, or a lifetime. The group also seeks research into gender specific biological and medical problems that affect women only, and for efforts to reduce or eliminate HIV/AIDS globally. The summit will be held Oct. 8-10, 2018. Claim: Pittsburgh-based Magee-Womens institute to offer $1M prize.

SOLUTION:
The Pittsburgh-based Magee-Womens Research Institute is planning to offer a $1 million prize for innovative research into women’s health when it holds its inaugural summit next October at the city’s David L. Lawrence Convention Center.
