Horrific details emerging from El Fasher, Sudan: pools of blood so large they’re visible by satellite, people being killed systematically. Last week, MSF teams assessed 165 children under 5 fleeing the area and found 75% were acutely malnourished. An accelerating genocide before our eyes.

Expansion of aerobic methanotrophy to the phylum of Actinomycetota and its environmental implications | Applied and Environmental Microbiology
The climate crisis is one of the most imminent threats to humanity and all life on our planet. Methane is not only the second most potent greenhouse gas (GHG) and is responsible for approximately 31% of GHG-induced global warming since the start of the industrial revolution (1) but is also the most rapid increasing GHG in the atmosphere (2). The latter is likely caused by increased microbiological production of methane from, e.g., wetlands (2). This fact stresses the importance of methanotrophic microbes that can degrade methane with and without oxygen (3, 4) and thereby fulfill a crucial role in our global climate.
