Global food safety research agreement signed by China and UC Davis
(University of California - Davis) An agreement establishing a collaborative global food safety research center in China was signed today by officials from China's Northwest Agricultural and Forestry University and the University of California, Davis.

How honey bees stay cool
(Tufts University) Recently published research led by Philip T. Starks, a biologist at Tufts University's School of Arts and Sciences, is the first to show that worker bees dissipate excess heat within a hive in process similar to how humans and other mammals cool themselves through their blood vessels and skin.

Spinach could lead to alternative energy more powerful than Popeye
(Purdue University) Spinach gave Popeye super strength, but it also holds the promise of a different power for a group of scientists: the ability to convert sunlight into a clean, efficient alternative fuel. Purdue physicists are using spinach to study the proteins involved in photosynthesis, the process by which plants convert the sun's energy into carbohydrates used to power cellular processes. Artificial photosynthesis could allow for the conversion of solar energy into renewable, environmentally friendly hydrogen-based fuels.

Fires in the Northern Territories July 2014
(NASA/Goddard Space Flight Center) Environment Canada has issued a high health risk warning for Yellowknife and surrounding area because of heavy smoke in the region due to forest fires. In the image taken by the Aqua satellite, the smoke is drifting eastward along normal wind patterns. Fire is an obvious health hazard, but the smoke that comes from fires is not quite so obvious and its effects are insidious.

Climate change and the soil
(Carnegie Institution) The planet's soil releases about 60 billion tons of carbon into the atmosphere each year, which is far more than that released by burning fossil fuels. Short-term warming studies have documented that rising temperatures increase the rate of soil respiration. As a result, scientists have worried that global warming would accelerate the decomposition of carbon in the soil, releasing more carbon dioxide into the atmosphere and accelerating global warming.

Calcification in changing oceans explored in special issue of The Biological Bulletin
(Marine Biological Laboratory) The July issue of the Biological Bulletin, published by the Marine Biological Laboratory, addresses the challenges faced by calcifiers -- organisms that use calcium from their environment to create hard carbonate skeletons and shells for stability and protection -- as ocean composition changes worldwide.

Research charts the ecological impact of microbial respiration in the oxygen-starved ocean
(University of British Columbia) A sulfur-oxidizing bacterial group called SUP05 will play an increasingly important role in carbon and nutrient cycling in the world's oceans as oxygen minimum zones expand, according to research published this week in the Proceedings of the National Academy of Sciences.

An increase in temperature by 2050 may be advantageous to the growth of forage plants
(Fundao de Amparo Pesquisa do Estado de So Paulo) A 2C increase in temperature around the world by 2050, according to one of the scenarios predicted by the Intergovernmental Panel on Climate Change, may be advantageous to the physiology and the biochemical and biophysical processes involved in the growth of forage plants such as Stylosanthes capitata Vogel, a legume utilized for livestock grazing in tropical countries such as Brazil.

Urban heat boosts some pest populations 200-fold, killing red maples
(North Carolina State University) New research shows that urban 'heat islands' are slowly killing red maples in the southeastern United States. One factor is that researchers have found warmer temperatures increase the number of young produced by the gloomy scale insect -- a significant tree pest -- by 300 percent, which in turn leads to 200 times more adult gloomy scales on urban trees.

Rosemary and oregano contain diabetes-fighting compounds
(American Chemical Society) The popular culinary herbs oregano and rosemary are packed with healthful compounds, and now lab tests show they could work in much the same way as prescription anti-diabetic medication, scientists report. In their new study published in the American Chemical Society's Journal of Agricultural and Food Chemistry, they found that how the herbs are grown makes a difference, and they also identified which compounds contribute the most to this promising trait.
