Abstract In order to better characterize the rich supernova remnant (SNR) population of M83 (NGC 5236), we have obtained high-resolution (∼85 km s −1 ) spectra 119 SNRs and SNR candidates in with Gemini/GMOS, as well new young B12-174a SN 1957D. Most [S ii ]:H α ratios that exceed 0.4. Combining these results earlier studies carried out MUSE at lower spectroscopic resolution GMOS, confirmed a t...

Empirical evidence from research on Bt maize in Kenya puts to rest most concerns raised against GMOs (not responding to farmers’ needs, expensive, benefiting agro-business, risk of decreased biodiversity), but does indicate that contamination of local varieties is likely and buildup of insect resistance possible, requiring careful monitoring and evaluation.

Progress in genetic engineering has led to the introduction of genetically modified organisms (GMOs) whose genomes have been altered by the integration of a novel sequence conferring a new trait. To allow consumers an informed choice, many countries require food products to be labeled if the GMO content exceeds a certain threshold. Consequently, the development of analytical methods for GMO scr...

FAO promotes Sustainable Production Intensification (SPI), which consists of a technology menu for optimizing crop production per unit area, taking into consideration the range of sustainability aspects including potential and/or real social, political, economic and environmental impacts. The author suggests that Genetically Modified Organism (GMO) cropping is not only well aligned to SPI but a...

Executive Summary This Report This report is motivated by the conclusions of EU Council of Environment Ministers of December 4, 2008, asking the European Commission to explore the possibility to consider other factors beyond health and environmental risks, i.e. " socioeconomic benefits and risks and agronomic sustainability " (all covered by the term socioeconomic in this report) in GMO market ...

The intensification of agriculture has provided cheaper more plentiful food, but has also caused declines in farmland wildlife. The introduction of genetically modified (GM) crops may exacerbate this, or offer new ways of mitigating anthropogenic impacts. The potential consequences of the introduction of GM crops have been studied for over a decade, since commercialization. Although the specifi...

Genetically modified organisms (GMOs) can be defined as organisms in which the genetic material (DNA) has been altered in a way that does not occur naturally. The technology is often called “modern biotechnology” or “gene technology”, sometimes also “recombinant DNA technology” or “genetic engineering”. It allows selected individual genes to be transferred from one organism into another, also b...
