Globale Plastikverschmutzung im Fokus - Sonnenseite - Ökologische Kommunikation mit Franz Alt

Globale Plastikverschmutzung im Fokus
Die gegenwärtigen Raten der globalen Plastikemissionen könnten Effekte auslösen, die wir nicht mehr rückgängig machen können, berichten Forschende aus Deutschland, Schweden und Norwegen in einer neuen Studie.
Nach Ansicht der Autorinnen und Autoren ist die Plastikverschmutzung eine globale Bedrohung und Maßnahmen zur drastischen Reduzierung der Plastikemissionen in die Umwelt seien „die rationale politische Antwort“.
Plastik ist überall auf dem Planeten zu finden: von Wüsten und Berggipfeln bis zu tiefen Ozeanen und arktischem Schnee. Im Jahr 2016 reichten die Schätzungen der weltweiten Emissionen von Plastik in Seen, Flüsse und Ozeane von 9 bis 23 Millionen Tonnen pro Jahr, wobei eine ähnliche Menge jährlich an Land emittiert wird. Es wird erwartet, dass sich diese Schätzungen bis zum Jahr 2025 fast verdoppeln werden, wenn die Weltbevölkerung weitermacht, wie bisher ( ....

Latest Neuropixels probes can track neurons over weeks


Latest Neuropixels probes can track neurons over weeks
A new generation of miniature recording probes can track the same neurons inside tiny mouse brains over weeks and even months.
LEUVEN (Belgium), April 20, 2021 The new tools build on the success of the original Neuropixels probes released in 2017 and currently used in more than 400 labs. Neuropixels 2.0 are much smaller about a third the size of their predecessors. They’re designed to record the electrical activity from more individual neurons and have the unique ability to track this activity over extended time periods. That makes them especially useful for studying long-term phenomena like learning and memory in small animals such as mice, says Tim Harris, a senior fellow at HHMI’s Janelia Research Campus who led the project. Harris and his colleagues describe the advance in a paper published online April 16 in the journal ....
