Independent, accurate nonprofit news since 1921. A transgenic individual can later be bred to homozygosity and maintained as an inbred line to reduce the need to confirm the genotype of each individual. Global warming may have played a role, because the development of that frog is typical for this area may have been compromised. ", Oliva, Karen, and Chad Rector.

The Republic lasted from 1823 to 1838, when it disintegrated as a result of civil wars. Scientists still dont know much about the impacts of deep-sea mining, and what they do know suggests that it could be incredibly destructive, underscoring a core tension in the race to reduce greenhouse gas emissions: Some technologies come at the expense of biodiversity and its often not clear how to weigh the trade-offs. 2019;380(9):842849.
