Environmental DNA analysis makes it possible to detect water organisms without having to capture them first. For the first time, a team at the Technical University of Munich (TUM) systematically investigated the effect of various environmental factors on environmental DNA analyses. By doing so, the researchers have made an important step towards the standardized application of this method for the monitoring of water bodies.

A protein involved in cognition and storing long-term memories looks and acts like a protein from viruses. The protein, called Arc, has properties similar to those that viruses use for infecting host cells, and originated from a chance evolutionary event that occurred hundreds of millions of years ago.

In a new commentary in the journal Nature Climate Change, IIASA researchers argue that a broader range of scenarios is needed to support international policymakers in the target of limiting climate change to under 2°C above pre-industrial levels, and to avoid potential negative environmental and social consequences of carbon dioxide removal on a massive scale. 

En un nuevo comentario en la revista Nature Climate Change, los investigadores de IIASA argumentan que se necesita una gama más amplia de escenarios para apoyar a los formuladores de políticas internacionales en el objetivo de limitar el cambio climático a menos de 2 ° C por encima de los niveles preindustriales, y evitar potenciales y las consecuencias sociales de la eliminación de dióxido de carbono a gran escala.
