New study finds genetically engineered crops could play a role in sustainable agriculture

...d genetic engineering are controversial because of concerns about risks to human health and biodiversity, but few analyses exist that reveal the actual effects genetically modified plants have on other non-modified species. In an analysis of 42 field experiments, scientists found that this particular modific...

Are journal rankings distorting science?

This week’s BMJ raises concerns over whether journal rankings (known as impact factors) are distorting publishing and science. The impact factor is a measure of the citations to papers in scientific journals. It was developed as a simple measure of quality and has become a proxy f...
