  1. X-ray Vision Puts Plants, Dirt on World StageA multidisciplinary team of scientists at The Univ. of Nottingham are using some of the most advanced X-ray micro Computed Tomography (CT) scanners to learn how to design plant roots so they can interact better with soil and capture water and nutrients more efficiently. This non-invasive technology will help Nottingham unearth some of the answers to one of the biggest challenges facing the world today — global food security.Malcolm Bennett, professor of plant sciences, says, “For the first time in 10,000 years of plant breeding, we can see a plant’s root architecture directly in the soil, as it is in the field, and use this information to select the most efficient varieties for farmers to grow.”Read more: http://www.laboratoryequipment.com/news/2014/09/x-ray-vision-puts-plants-dirt-world-stage

  3. FDA to Tweak Food Safety RulesThe government said Friday it will rewrite sweeping new food safety rules after farmers complained that earlier proposals could hurt business. New proposals by the Food and Drug Administration would make it easier for farmers to meet water quality standards and allow farmers to harvest crops sooner after using raw manure as fertilizer.The FDA proposed the revised rules Friday, and the final rules are due next fall. The FDA has been haggling over how to write them for four years since Congress passed a food safety law in 2010. Regulators say it has been a challenge to balance the need for tighter food safety standards in the wake of major outbreaks in spinach, eggs, peanuts and cantaloupe along with the needs of farmers who are new to such regulations.Read more: http://www.laboratoryequipment.com/news/2014/09/fda-tweak-food-safety-rules

  5. Communal Nesting Confuses Paternity, Reduces InfanticideIt is a cruel world out there, particularly for young animals born into social groups where infanticide occurs. This dark side of evolution is revealed when adults – often males – kill offspring to promote their own genes being passed on, by reducing competition for resources or making females become sexually receptive more quickly.This behavior proves expensive for females, who have evolved strategies to avoid this fate. One strategy is to join forces with other females to physically ward off killer males. A more interesting strategy is to mate with several males, known as “polyandry,” so fathers can’t distinguish their young from others’, which means they avoid killing pups so that they don’t accidently kill their own.Now, researchers at the Univ. of Zurich have found a new type of infanticide counter-strategy: mothers can achieve paternity confusion even if they don’t mate with multiple males, through nesting with other females, which they call “socially mediated polyandry.” And such a strategy might be happening close to home, in the unassuming house mouse.Read more: http://www.laboratoryequipment.com/news/2014/09/communal-nesting-confuses-paternity-reduces

Corn Yields Depend on Nutrient BalanceEnsuring that corn absorbs the right balance of nitrogen, phosphorus and potassium is crucial to increasing global yields, a Purdue and Kansas State Univ. study finds.A review of data from more than 150 studies from the U.S. and other regions showed that high yields were linked to production systems in which corn plants took up key nutrients at specific ratios — nitrogen and phosphorus at a ratio of five to one and nitrogen and potassium at a ratio of one to one. These nutrient uptake ratios were associated with high yields regardless of the region where the corn was grown.Read more: http://www.laboratoryequipment.com/news/2014/09/corn-yields-depend-nutrient-balance

  27. Dogs Can Be Pessimists

    Dogs generally seem to be cheerful, happy-go-lucky characters, so you might expect that most would have an optimistic outlook on life. But, some dogs are distinctly more pessimistic than others, research from the Univ. of Sydney shows.

    "This research is exciting because it measures positive and negative emotional states in dogs objectively and non-invasively. It offers researchers and dog owners an insight into the outlook of dogs and how that changes," said Melissa Starling, from the Faculty of Veterinary Science. Her PhD research findings are published in PLOS. "Finding out as accurately as possible whether a particular dog is optimistic or pessimistic is particularly helpful in the context of working and service dogs and has important implications for animal welfare."
