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.
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.

Paragraph: A developmental biologist and tissue engineer, Dr. Mironov, 56, is one of only a few scientists worldwide involved in bioengineering "cultured" meat. It's a product he believes could help solve future global food crises resulting from shrinking amounts of land available for growing meat the old-fashioned way ... on the hoof. Growth of "in-vitro" or cultured meat is also under way in the Netherlands, Mironov told Reuters in an interview, but in the United States, it is science in search of funding and demand. The new National Institute of Food and Agriculture, part of the U.S. Food and Drug Administration, won't fund it, the National Institutes of Health won't fund it, and the National Aeronautics and Space Administration funded it only briefly, Mironov said. "It's classic disruptive technology," Mironov said. "Bringing any new technology on the market, average, costs $1 billion. We don't even have $1 million." Director of the Advanced Tissue Biofabrication Center in the Department of Regenerative Medicine and Cell Biology at the medical university, Mironov now primarily conducts research on tissue engineering, or growing, of human organs. "There's a yuck factor when people find out meat is grown in a lab. They don't like to associate technology with food," said Nicholas Genovese, 32, a visiting scholar in cancer cell biology working under a People for the Ethical Treatment of Animals three-year grant to run Dr. Mironov's meat-growing lab. "But there are a lot of products that we eat today that are considered natural that are produced in a similar manner," Genovese said. "There's yogurt, which is cultured yeast. You have wine production and beer production. These were not produced in laboratories. Society has accepted these products." If wine is produced in winery, beer in a brewery and bread in a bakery, where are you going to grow cultured meat? In a "carnery," if Mironov has his way. That is the name he has given future production facilities. He envisions football field-sized buildings filled with large bioreactors, or bioreactors the size of a coffee machine in grocery stores, to manufacture what he calls "charlem" "Charleston engineered meat." "It will be functional, natural, designed food," Mironov said. "How do you want it to taste? You want a little bit of fat, you want pork, you want lamb? We design exactly what you want. We can design texture. "I believe we can do it without genes. But there is no evidence that if you add genes the quality of food will somehow suffer. Genetically modified food is already normal practice and nobody dies." Dr. Mironov has taken myoblasts embryonic cells that develop into muscle tissue from turkey and bathed them in a nutrient bath of bovine serum on a scaffold made of chitosan (a common polymer found in nature) to grow animal skeletal muscle tissue. But how do you get that juicy, meaty quality? Genovese said scientists want to add fat. And adding a vascular system so that interior cells can receive oxygen will enable the growth of steak, say, instead of just thin strips of muscle tissue. Cultured meat could eventually become cheaper than what Genovese called the heavily subsidized production of farm meat, he said, and if the public accepts cultured meat, the future holds benefits. "Thirty percent of the earth's land surface area is associated with producing animal protein on farms," Genovese said. "Animals require between 3 and 8 pounds of nutrient to make 1 pound of meat. It's fairly inefficient. Animals consume food and produce waste. Cultured meat doesn't have a digestive system. "Further out, if we have interplanetary exploration, people will need to produce food in space and you can't take a cow with you. "We have to look to these ideas in order to progress. Otherwise, we stay static. I mean, 15 years ago who could have imagined the iPhone?" Claim: South Carolina scientist works to grow meat in lab.
In a small laboratory on an upper floor of the basic science building at the Medical University of South Carolina, Vladimir Mironov, M.D., Ph.D., has been working for a decade to grow meat.

Paragraph: Duck droppings from the central Dutch province tested positive for the highly contagious H5 strain of the disease, the deputy economic affairs minister wrote in a letter to parliament. "Based on this information I am considering follow-up measures," deputy minister Sharon Dijksma wrote. Dutch authorities said earlier on Monday they will slaughter 50,000 birds at a poultry farm after bird flu was discovered nearby. Separate testing indicated that farm infections, which have led to the culling of around 300,000 birds at four locations, were not all from the same source, the letter said. The H5N8 strain of bird flu detected at the farms has never been founded in humans. It has led to the destruction of millions of farm birds in Asia, mainly South Korea, after an outbreak earlier this year. A government statement said tests had confirmed an outbreak of the H5N8 strain at one farm in the western municipality of Zoeterwoude, where 28,000 laying hens were ordered destroyed on Sunday. A cull at a nearby farm announced on Monday was a precautionary measure, it said. Animal health authorities are testing poultry at other farms in the area. Transport restrictions were imposed on the sector two weeks ago that have hit around 2,000 poultry businesses. The Netherlands is the world's largest exporter of eggs and the largest exporter of poultry meat in the European Union. Some experts believe that wild birds migrating from Asia carried the disease to Europe, where it infected flocks in Germany, Britain and the Netherlands. Claim: Dutch discover bird flu in wild ducks, cull continues.
Dutch animal health authorities found bird flu in two samples taken from wild ducks, a government statement said, but it was unclear if that was the source of an outbreak at four chicken farms in the Netherlands.
