with the unfolding #trumpocalypse I am wondering if scientific publications like #PNAS and #science magazine are safe from #Gleichschaltung. Any clues?

What is the Moon made of? And how did it get here?

Researchers from our Uni & @mpsgoettingen analysed samples from the Moon. Their results suggest that the Moon could in fact be a chunk ejected from the Earth’s mantel following a massive collision: https://s.gwdg.de/woj1iB

How is climate change going to affect Arctic shorelines? A new #PNAS #paper involving #MPI_scientist David Nielsen finds that, by 2100, there may be:
unprecedented land loss pushing the Alaskan coastline further inland than at any point in the last 100,000 years
potentially 8–11 times more carbon released than from coastal erosion alone, affecting marine ecosystems

Remember #Thwaites #glacier ? It's the glacier on west #Antarctica that's considered unstable as relatively warm seawater protrudes deep under the ice shelf in front of it. Turns out it's even more unstable as previously thought. Researchers found proof of seawater intrusions deep under the ice sheet itself.

Thwaites is believed to be responsible for about 4% of #sealevel rise. #Research paper in #PNAS:

Sometimes a good idea turns out to be even better than originally thought:
The emissions trading system #ETS of the #EU is built to reduce #CO2 emissions, but it has also generated large health benefits by reducing air pollution

This is the finding of a new study by #MPI_Scientist Jonas Grunau and colleagues, published in #PNAS

Structural Modifications Enhance Antibacterial Potency of Bacitracin

The team of N. Martin from Leiden University optimized the antibiotic bacitracin, leading to a 256-fold increase in activity and also showed activity against vancomycin-resistant strains.

The team made the compound's non-polar side chains more lipophilic, enhancing bacterial membrane anchoring and hydrophobic interactions.

"Cat 6 hurricanes have arrived" | My #PNAS commentary on the new @PNASNews article by @MichaelFWehner & Jim Kossin:

How does human #migration affect the prospects for #sustainabledevelopment
My #PNAS Special Feature with Neil Adger, Sonja Fansen and Ricardo Safra de Campos explores the relation of migration flows to #wellbeing , #inequality , #environment & #socialcapital : https://www.pnas.org/topic/554 (#openaccess).

Migration can deepen inequality & increase environmental damage but also can be a positive force for sustainability if managed well.

" #Amazon #deforestation causes strong regional #warming"
" #Tropical deforestation warms the #climate with negative impacts on people living nearby. Most previous studies have focused on the local warming caused by deforestation and less is known about how deforestation impacts surrounding areas. Our study used satellite data to show that deforestation in the Amazon caused substantial warming up to 100 km away from the location of forest loss. We show that this nonlocal warming increased deforestation-induced warming by a factor of four."

(Proceedings of the National Academy of Sciences #PNAS 30. October 2023, https://doi.org/10.1073/pnas.2309123120 )
...
"The regional warming due to Amazon deforestation will have negative consequences for the 30 million people living within the Amazon basin, many of whom are already exposed to dangerous levels of heat. Previous studies have suggested that the combined impacts of future climate change and deforestation could expose an additional 11 million people across the Amazon to extreme heat stress. Increased temperatures will reduce human productivity and increase all-cause human mortality for already marginalized communities. Increased temperatures will also impact livestock and reduce crop yields, exacerbated by deforestation-induced reductions in #rainfall. Increased regional temperatures caused by deforestation will also impact #carbon storage of remaining forest and increase the risk of fire, with the resultant haze having further consequences for human health."

So, like, we could have been doing this a thousand years ago?!

Carbon–cement supercapacitors as a scalable bulk energy storage solution | #PNAS

Our recent research in PNAS reveals the dynamic world of enzymes like never before!

We used NMR spectroscopy and CPMG relaxations to unveil hidden conformations, connecting them to enzymatic activity and inhibitor potency. Likely important for drug design! #NMR #Enzymes #PNAS
