Broccoli sprout extract promising for head and neck cancer prevention
(University of Pittsburgh Schools of the Health Sciences) Broccoli sprout extract protects against oral cancer in mice and proved tolerable in a small group of healthy human volunteers, the University of Pittsburgh Cancer Institute, partner with UPMC CancerCenter, announced today at the American Association for Cancer Research (AACR) Annual Meeting in Philadelphia.

2015 Joint Assembly: Preliminary press conference topics; Virtual Press Room now live
(American Geophysical Union) The AGU Public Information office is planning a number of press conferences to highlight newsworthy presentations at the 2015 Joint Assembly. So far, we expect briefings on craters, thunder, water contamination, mining, and wine-making in Canada. This list may grow and is subject to change. During the Joint Assembly, journalists can find press releases and many resources online in the Virtual Press Room in the Media Center on the Joint Assembly website.

Invasive parasitic fly on Galapagos Islands probably came from mainland Ecuador
(Entomological Society of America) Philornis downsi, an invasive parasitic fly that harms Darwin's finches and other land birds on the Galpagos Islands, has been found for the the first time in mainland Ecuador, supporting the hypothesis that it was introduced from there.

Stomach ulcers in cattle
(University of Veterinary Medicine -- Vienna) Scientists at the Vetmeduni Vienna investigated whether stomach ulcers in cattle are related to the presence of certain bacteria. For their study, they analyzed bacteria present in healthy and ulcerated cattle stomachs and found very few differences in microbial diversity. Bacteria therefore appear to play a minor role in the development of ulcers. The microbial diversity present in the stomachs of cattle has now for the first time been published in the journal Veterinary Microbiology.

Model offers more ease, precision for managing invasive Asian carp
(University of Illinois College of Engineering) The likelihood of Asian carp eggs being kept in suspension and hatching in the St. Joseph River in Michigan has been further evaluated using a model that examines a range of multiple flow and water temperature scenarios. Results illustrate the highest percentage of Asian carp eggs at risk of hatching occurs when the streamflow is low and when the water temperature is high.

ORNL researchers contribute to major UN bioenergy and sustainability report
(DOE/Oak Ridge National Laboratory) A major United Nations report on bioenergy and sustainability released Tuesday concludes the sustainable production of bioenergy can be an important tool for addressing climate change.

Study finds that maize roots have evolved to be more nitrogen efficient
(Penn State) Selective breeding of maize over the last century to create hybrids with desirable shoot characteristics and increased yield may have contributed indirectly to the evolution of root systems that are more efficient in acquiring nutrients, such as nitrogen, from the soil, according to researchers.

Fish type, body size can help predict nutrient recycling rates
(North Carolina State University) The nutrients excreted by fish in their 'pee' may be critical to the health of coastal ecosystems. But knowing whether generalizations can be made about how to predict these nutrient levels in various ecosystems has vexed researchers -- until now.

Expanding rubber plantations 'catastrophic' for endangered species in Southeast Asia
(University of East Anglia) Demand for natural rubber fueled by the tyre industry is threatening protected parts of Southeast Asia -- according to University of East Anglia research. A study predicts that up to 8.5 million hectares of additional rubber plantations will be required to meet demand by 2024. But expansion on this scale will have 'catastrophic' biodiversity impacts, with globally threatened unique species and ecosystems put under threat. The extent of the problem is comparable to oil palm.

A new online resource on the Asian longhorned beetle
(Entomological Society of America) A new, open-access article in the Journal of Integrated Pest Management provides a comprehensive overview of the Asian longhorned beetle, including a review of its biology, life stages, distribution, ecology, and methods of detecting and controlling it.
