Abstract. The Tammar wallaby (Macropus eugenii) harbors unique gut bacteria and produces only one-fifth the amount of methane produced by ruminants per unit of digestible energy intake. We have isolated a dominant bacterial species (WG-1) from the wallaby microbiota affiliated with the family Succinivibrionaceae and implicated in lower methane emissions from starch-containing diets. This was achieved by using a partial reconstruction of the bacteriums metabolism from binned metagenomic data (nitrogen and carbohydrate utilization pathways and antibiotic resistance) to devise cultivation-based strategies that produced axenic WG-1 cultures. Pure-culture studies confirm that the bacterium is capnophilic and produces succinate, further explaining a microbiological basis for lower methane emissions from macropodids. This knowledge also provides new strategic targets for redirecting fermentation and reducing methane production in livestock.. ...

Age can significantly affect human physiology and disease risk. Recent studies have shown that age may affect the composition and function of the gut microbiota, but the underlying mechanisms remain largely unknown. Non-human primates are an ideal model for uncovering how age shapes the gut microbiota, as their microbial composition is highly similar to that of humans and is not easily affected by confounding factors. Here, using the 16S rRNA and metagenomic sequencing methods, we characterized the microbial phenotypes of 16 female cynomolgus macaques from three age groups (young, adult and old). Our findings revealed significant differences in microbial composition among the three groups. With increased age, the relative abundances of Veillonellaceae, Coriobacteriaceae and Succinivibrionaceae were significantly increased, Ruminococcaceae and Rikenellaceae were significantly decreased at the family level. Functional enrichment showed that genes that differed among the

Our Children Our Future Our RESPONSIBLITY Annual Report of the North Carolina Child Fatality Task Force to the Governor and General Assembly Raleigh, North Carolina January 2017 January, 2017 The Honorable Roy Cooper Governor, State of North Carolina Distinguished Members of the North Carolina General Assembly At the end of 2016, past and present members and friends of the Child Fatality Task Force gathered to celebrate twenty-five years of advancing public policy to save childrens lives in North Carolina. Work of the Task Force has contributed to a 46% reduction in the states child death rate since creation of the Task Force and the larger Child Fatality Prevention System in 1991. The dedication and wisdom of those who started the Task Force is reflected in the efforts of the many hard-working experts and officials who served on the 2016 Task Force and contributed to the recommendations presented in this report. The Task Force provides a unique forum that brings together agency officials, ...

Also, the plan is to incorporate the management of methane emissions in maintenance plans, and the design and construction of their new projects. The companies have also committed to encourage these actions in non-operated assets.. Furthermore, the eight have pledged to reduce venting, fugitive methane emissions, and to improve combustion efficiency.. Also, they promised to implement systematic leak detection and repair programmes, prioritising potential higher emitting sources.T They will also focuse on implementing and further development of effective technologies and practices for monitoring and reducing methane emissions, and consider them in them project engineering and design.. The eight energy firms have said they would provide financial and operational support for the development and deployment of innovative technologies and approaches that monitor and reduce methane emissions.. Numerous studies have shown the importance of quickly reducing methane emissions if were to meet growing ...

The Obama Administrations push to cut methane emissions puts a bulls-eye on an issue that has long drawn criticism of the agriculture industry from environmentalists. But the White Houses proposals for curbing gas emitted by livestock are relatively tame.

Per capita methane emissions are measured in tonnes of carbon-dioxide equivalents (CO|sub|2|/sub|e) per person per year. This metric converts all greenhouse gases to CO|sub|2|/sub|e based on their global warming potential value over a 100-year timescale.

The fossil fuel industry may be responsible for a much greater share of the worlds methane emissions than previously estimated, according to new research

The EPA has proposed a roll back on methan emission regulations on Thursday. This will no longer require oil and gas companies to use monitoring technology.

Global methane emissions soar to record high The pandemic has tugged carbon emissions down, temporarily. But levels of the powerful heat-trapping gas methane continue to climb, dragging the world furt

The Canadian oil and gas industry could be emitting methane at rates 25 to 50 percent higher than official estimates, according to a new published study.

A new U.S. Environmental Protection Agency (EPA) study released last week indicates the agency may be greatly exaggerating oil and natural gas system methane emissions. By using a combination of extractive air sampling and remote optical gas imaging (OGI) tools to analyze 80 pneumatic control systems across eight well pads, the study found oil and gas methane emissions in Utahs Uinta Basin are

While carbon dioxide is more abundant in the atmosphere and therefore more commonly associated with global warming, methane is around 30 times more potent as a heat-trapping gas. Given its importance, Canadian company GHGSat have worked in collaboration with the Sentinel-5P team at SRON Netherlands Institute for Space Research to investigate hotspots of methane emissions during COVID-19.
