A new University of Colorado Boulder framework used to screen hundreds of organic chemical compounds used in hydraulic fracturing, or fracking, shows that 15 may be of concern as groundwater contaminants based on their toxicity, mobility, persistence and frequency of use.
A new study from Indiana University provides evidence in mice that males may play a positive role in the development of offspring's brains starting before pregnancy.
The larvae of some species of reef fish appear to survive better depending on the timing of when they were spawned, according to new research from the National Institute for Mathematical and Biological Synthesis.
Carnegie Mellon University chemists have developed two novel methods to characterize 3-D macroporous hydrogels -- materials that hold great promise for developing 'smart' responsive materials that can be used for catalysts, chemical detectors, tissue engineering scaffolds and absorbents for carbon capture.
A University of Georgia researcher is lead author on an international paper on folate biomarkers as part of an initiative to provide evidence-based guidance for the global nutrition and public health community. UGA's Lynn Bailey led a comprehensive study on folate, an essential B vitamin required for DNA synthesis and normal growth and development. The paper, published in the Journal of Nutrition, represents a consensus of the top folate scientists globally.
Salk scientists find that dietary fat, coupled with a natural hormone, can relieve metabolic dysfunction associated with mitochondrial disease in mice.
People on a vegetarian diet, and especially those following a vegan one that includes no animal products, see better results than dieters on other weight-reducing plans. In fact, they can lose around two kilograms more on the short term, says Ru-Yi Huang of E-Da Hospital in Taiwan after reviewing the results of twelve diet trials. The findings appear in the Journal of General Internal Medicine, published by Springer.
University of Washington researchers have produced cell-to-cell communication in baker's yeast -- a first step in learning to build multicellular organisms or artificial organs from scratch.
As floodwaters surge along major rivers in the midwestern United States, a new study from Washington University in St. Louis suggests federal agencies are underestimating historic 100-year flood levels on these rivers by as much as five feet, a miscalculation that has serious implications for future flood risks, flood insurance and business development in an expanding floodplain.
In a paper recently published in the International Journal of Water, civil engineering graduate Ryan Calder evaluates claims that more centralized US-style regulation of drinking water would improve outcomes for Canadians. The paper finds limited support for these claims but suggests they reflect deeply held Canadian political and cultural values.
