Increasing amounts of metal, such as lithium, as a byproduct of the modern-day space race, are beginning to alter the chemical composition of Earth’s atmosphere. 
Robin Wing, and his colleagues at the Leibniz Institute of Atmospheric Physics at the University of Rostock in Germany, measured a 10-fold concentration of lithium atoms in the upper atmosphere around 20 hours after the uncontrolled re-entry of a Falcon 9 rocket.
The findings are detailed in a new studypublished Thursda…

Study Confirms: Reentering SpaceX Rockets Are Peppering the Upper Atmosphere With Metal Pollution
For the first time, scientists were able to directly detect upper-atmospheric pollution from space debris.

Abstract: We show that on certain diffeological spaces there exist linear derivations that satisfy the Leibniz rule but are not smooth with respect to the given diffeology. This reveals that the notion of tangent space defined via all such derivations is strictly larger than the one defined using only smooth derivations, showing that smoothness cannot be recovered from the Leibniz rule alone.

Why the Baltic Sea still chokes after decades of nutrient controls
The Baltic Sea has been under pressure for decades: Although phosphorus and nitrogen river loads, the main cause for its eutrophication, have been significantly reduced, adverse effects such as algal blooms and oxygen depletion still massively occur, leading to further ecological problems. Scientists at the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) have now published a comprehensive review showing how nutrient pollution, internal matter cycles and global warming interact, ther…

Record low sea levels in the Baltic Sea could reshape sea's physical conditions
Since the beginning of January, an unusually long period of easterly winds has caused the average water level in the Baltic Sea to fall to a historic low. Measurements at the Swedish Landsort-Norra gauge show values that are the lowest since records began in 1886. Researchers at the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) are currently monitoring this development very closely, as it represents a rare oceanographic situation that could lead to a large inflow of saltwater from…
