| 40 percent of surface disinfectants ineffective in eliminating viruses that cause gastroenteritis Wed, 17 Mar 2010 00:00:00 EDT |
(Université Laval) Some 40 percent of commercial disinfectants used to clean surfaces are believed to be ineffective in eliminating noroviruses, a group of viruses responsible for more than half of all food-borne gastroenteritis outbreaks. According to a recent study published by Université Laval researchers in the Journal of Food Protection, only bleach-based disinfectants drastically reduce the concentration of these viruses. |
| Prior herbicide use -- not irrigation -- is critical to herbicide efficacy Wed, 17 Mar 2010 00:00:00 EDT |
(United States Department of Agriculture-Research, Education, and Economics) Crop and herbicide use history are more critical to herbicide efficacy and environmental safety than the timing and amount of irrigation water used, according to Agricultural Research Service scientists. |
| An organic approach to pest control -- releasing super-sexed (but sterile) male insects Wed, 17 Mar 2010 00:00:00 EDT |
(The Hebrew University of Jerusalem) An improved method for sustainable pest control using "super-sexed" but sterile male insects to copulate with female ones is being developed by agricultural researchers at the Hebrew University of Jerusalem. The scientists thus hope to offer yet another efficient and promising avenue for supplying produce to the market by eliminating pests without damage to the environment. |
| Sharks from deep waters of Cantabrian Sea are opportunist hunters Wed, 17 Mar 2010 00:00:00 EDT |
(FECYT - Spanish Foundation for Science and Technology) A team of Spanish researchers has studied the diet of three species of sharks living in the deep waters in the area of El Cachucho, the first Protected Marine Area in Spain, which is located in the Cantabrian Sea off the coast of Asturias. These animals feed on the resources available in their environment, according to changes taking place in the ocean depths. |
| A marine Mr. Mom: Male pipefish gives birth, but some are deadbeat dads, study shows Wed, 17 Mar 2010 00:00:00 EDT |
(Texas A&M University) Male pipefishes and their seahorse cousins are the only males that actually become pregnant and give birth, but pipefishes likely will never win any "Father of The Year" awards -- their attitude towards their offspring can range from total love to total neglect, according to new findings from Texas A&M University researchers. |
| Brandeis scientists sniff out the evolution of chemical nociception Wed, 17 Mar 2010 00:00:00 EDT |
(Brandeis University) Whenever you choke on acrid cigarette smoke, feel like you're burning up from a mouthful of wasabi-laced sushi, or cry while cutting raw onions and garlic, your response is being triggered by a primordial chemical sensor conserved across some 500 million years of animal evolution, report Brandeis University scientists in a study in Nature this week. |
| Fungi can change quickly, pass along infectious ability Wed, 17 Mar 2010 00:00:00 EDT |
(Oregon State University) Fungi have significant potential for "horizontal" gene transfer, a new study has shown, similar to the mechanisms that allow bacteria to evolve so quickly, become resistant to antibiotics and cause other serious problems. |

| New biotech advance to add heart healthy omega-3s to US diet Tue, 16 Mar 2010 00:00:00 EDT |
(United Soybean Board) A new heart-healthy, essential omega-3 fatty acid is about to improve an American pantry staple: soybean oil. US soybean farmers are applying this scientific advance and other biotechnology to benefit the environment, human health and feed the world. |
| Frogs, foam and fuel: University of Cincinnati researchers convert solar energy to sugars Tue, 16 Mar 2010 00:00:00 EDT |
(University of Cincinnati) In natural photosynthesis, plants take in solar energy and carbon dioxide and then convert it to oxygen and sugars. The oxygen is released to the air and the sugars are dispersed throughout the plant -- like that sweet corn we look for in the summer. Unfortunately, the allocation of light energy into products we use is not as efficient as we would like. Now engineering researchers at the University of Cincinnati are doing something about that. |
| Jaws -- 4 million B.C. Tue, 16 Mar 2010 00:00:00 EDT |
(Wiley-Blackwell) Palaeontologists have discovered evidence of how an extinct shark attacked its prey, reconstructing a killing that took place 4 million years ago, reports the journal Palaeontology. |
| Catastrophic flooding may be more predictable after Penn researchers build a mini river delta Tue, 16 Mar 2010 00:00:00 EDT |
(University of Pennsylvania) Researchers created a miniature river delta that replicates flooding patterns seen in natural rivers, resulting in a mathematical model capable of aiding in the prediction of the next catastrophic flood. |
| From international harbor to native habitat Tue, 16 Mar 2010 00:00:00 EDT |
(Ecological Society of America) In the 1930s, soil used as ballast to weigh down cargo ships from South America to Mobile, Alabama introduced the red imported fire ant to the southern United States. Since then, the ants have been found as far north as Maryland and as far west as California, shorting out streetlights and eating through crops and native plants in the process. |
| New lentil being readied for market Tue, 16 Mar 2010 00:00:00 EDT |
(United States Department of Agriculture-Research, Education, and Economics) "Essex," a new lentil variety developed by Agricultural Research Service scientists, has a lot to offer: high seed yields for growers, nitrogen-fixing bacteria for wheat crops, and a tasty source of protein for consumers to add to soups, salads and other fare. |
| Major report reveals the environmental and social impact of the 'livestock revolution' Tue, 16 Mar 2010 00:00:00 EDT |
(Stanford University) Global meat production has tripled in the past three decades and could double its present level by 2050, according to a major report on the livestock industry by an international team of scientists and policy experts. The impact of this "livestock revolution" is likely to have significant consequences for human health, the environment and the global economy, the authors conclude. |
| Sea lice treatment increased in Norwegian fish breeding in 2009 Tue, 16 Mar 2010 00:00:00 EDT |
(Norwegian Institute of Public Health) A large increase in sales of agents used in sea lice infestations was seen in 2009. There was also a smaller increase in the use of antibacterials and anesthetics for fish. Sales of anthelmintics and fungicides were lower than in 2008. Increasing resistance to sea lice treatment has led to the reintroduction of many older drugs that have not been used for many years. |
| African bird discovery proves there is something new under the sun Tue, 16 Mar 2010 00:00:00 EDT |
(Texas A&M AgriLife Communications) "Four and 20 black birds baked in a pie" -- but wait, one has blue-gray eyes.That discovery, backed by DNA analysis, means scientists now know there is one more species of black shrike in the Albertine Rift of Africa than was previously thought. And if Dr. Gary Voelker has his way, he'll soon be studying the bird's habits to determine its susceptibility to the deforestation now occurring across its native habitat. |
| Study highlights forest protected areas as a critical strategy for slowing climate change Tue, 16 Mar 2010 00:00:00 EDT |
(World Wildlife Fund) A new study involving scientists from 13 different organizations, universities and research institutions states that forest protection offers one of the most effective, practical, and immediate strategies to combat climate change. The study, "Indigenous Lands, Protected Areas and Slowing Climate Change," was published in PLoS Biology, a peer-reviewed scientific journal, and makes specific recommendations for incorporating protected areas into overall strategies to reduce emissions of greenhouse gasses from deforestation and degradation (nicknamed REDD). |
| Thrill-seeking holiday-makers are putting dolphins at risk Tue, 16 Mar 2010 00:00:00 EDT |

| Urged on by urchins: How sea lilies got their get-up-and-go Mon, 15 Mar 2010 00:00:00 EDT |
(University of Michigan) Nature abounds with examples of evolutionary arms races. Certain marine snails, for example, evolved thick shells and spines to avoid be eaten, but crabs and fish foiled the snails by developing shell-crushing claws and jaws. |
| Study: Grass, fungus combination affects ecology Mon, 15 Mar 2010 00:00:00 EDT |
(Rice University) Fescue grass covers an area equivalent to 12 million football fields in the US, and a new study by ecologists at Rice University and Indiana University shows that the grass and a symbiotic fungus can affect local ecosystems in significant ways. Study results appearing in the Journal of Applied Ecology show that the genetic identity of an invisible fungus living symbiotically in fescue can alter the surrounding composition and diversity of the plant community. |
| How plants put down roots Mon, 15 Mar 2010 00:00:00 EDT |
(Max-Planck-Gesellschaft) Scientists from the Max Planck Institute for Developmental Biology have investigated how the thale cress, Arabidopsis thaliana, forms its first roots: the root founder cell in the tiny group of cells contained in the seed is activated by a combination of a plant hormone and a transcription factor. These insights could contribute to the breeding of plants with a particularly effective root system in the future. |
