Gut microbiota: The difference diet makes to metabolites and microbiota- TERA

The metabolomes and gut microbiotas of Northeastern US urban-dwelling vegan and omnivorous citizens have been compared in a new study published in Gut. Surprisingly, gut microbial composition differed modestly between groups but the plasma metabolomes varied considerably. doi: http://dx.doi.org/10.1038/nrgastro.2014.227

Life Cycle Assessment of Hysterectomy in the United States- TERA

The healthcare sector is a driver of economic growth in the U.S., with spending on healthcare in 2012 reaching $2.8 trillion, or 17% of the U.S. gross domestic product, but it is also a significant source of emissions that adversely impact environmental and public health. The current state of the healthcare industry offers significant opportunities [...]

Economic and Environmental Assessment of Office Building Rainwater Harvesting Systems in Various U.S. Cities- TERA

Rainwater harvesting (RWH) systems implemented in office buildings under heterogeneous urban settings in the United States, including combined and separated storm sewer systems, will result in varying environmental and economic costs and benefits across multiple water sectors. The potable water saving and stormwater abatement potentials were found to strongly correlate with the local annual precipitation [...]

Acidification Means Decreasing Growth, Reproduction, and Survival for Calcifying Marine Species

Increasing CO2 atmospheric levels lead to increasing ocean acidification, thereby enhancing calcium carbonate dissolution of calcifying species. We gathered peer-reviewed experimental data on the effects of acidified seawater on calcifying species growth, reproduction, and survival. The data were used to derive species-specific median effective concentrations, i.e., pH50, and pH10, via logistic regression. Subsequently, we developed [...]

Radiological Dose Rates to Marine Fish from the Fukushima Daiichi Accident: The First Three Years Across the North Pacific

A more complete record is emerging of radionuclide measurements in fish tissue, sediment, and seawater samples from near the Fukushima Daiichi Nuclear Power Plant (FDNPP) and across the Pacific Ocean. Our analysis of publicly available data indicates the dose rates to the most impacted fish species near the FDNPP (median 1.1 mGy d–1, 2012–2014 data) [...]

Forecasted coral reef decline in marine biodiversity hotspots under climate change- TERA

Coral bleaching events threaten coral reef habitats globally and cause severe declines of local biodiversity and productivity. Related to high sea surface temperatures, bleaching events are expected to increase as a consequence of future global warming. However, response to climate change is still uncertain as future low latitude climatic conditions have no present-day analogue. Sea [...]

EU regulator calls for generic drug suspensions of up to 700 medications- TERA

The European Medicines Agency (EMA) has accused an Indian contract research organisation (CRO) of systematic fraud, and has recommended suspending sales of hundreds of generic drug formulations in Europe because their approval is based on questionable clinical trial data. The EMA investigated products tested at the GVK Biosciences site in Hyderabad. This included about 1000 [...]

A simple approach for assigning conservation status based on natural variability- TERA

A simple, non-lethal method for assigning conservation status is proposed based on three conservation classes (favourable, unfavourable/inadequate and unfavourable/bad) to fish species based on their natural population variability. To demonstrate this approach, conservation classes were allocated to three native fish species (brown trout Salmo trutta L., northern Iberian chub Squalius carolitertii(Doadrio), and northern straight-mouth nase, Pseudochondrostoma duriense (Coelho) based on [...]

Photosynthetic terpene hydrocarbon production for fuels and chemicals- TERA

Photosynthetic hydrocarbon production bypasses the traditional biomass hydrolysis process and represents the most direct conversion of sunlight energy into the next-generation biofuels. As a major class of biologically derived hydrocarbons with diverse structures, terpenes are also valuable in producing a variety of fungible bioproducts in addition to the advanced ‘drop-in’ biofuels. However, it is highly [...]

Tilapia polyculture: a global review- TERA

Tilapia are the second most farmed fish worldwide and their production has quadrupled over the past decade due to ease of aquaculture, marketability and stable market prices. Tilapia aquaculture must adopt sustainable practices (such as polyculture) for continuing increased production and improved sustainability. This article reviews tilapia polyculture around the world and discusses its benefits, [...]
