Naturally Occurring 'GM' Butterflies Produced by Gene Transfer of Wasp-Associated Viruses

Sep. 17, 2015 — Research teams have discovered that genes originating from parasitic wasps are present in the genomes of many butterflies. These genes were acquired through a wasp-associated virus that integrates ... read more

Sep. 17, 2015 — Altered or new environmental conditions, such as those brought about by climate change, impose challenges on living organisms. This can drive species to extinction if they fail to adapt or adjust ... read more

Counting Underwater Vital for Marine Conservation

Sep. 16, 2015 — Understanding how genetic diversity occurs within species is paramount for conservation, according to scientists. The new research identified regions of high and low multi-species genetic diversity ... read more

Sep. 16, 2015 — Female butterflies generally choose among male suitors, but with hundreds of related species living in close proximity, how can they decide which are the right ones? A solution is that males have ... read more

Synthetic Biology Needs Robust Safety Mechanisms Before Real World Application
