(University of Helsinki) Global warming already affects Siberian primrose, a plant species that is threatened in Finland and Norway. According to a recently completed study, individuals of Siberian primrose originating in the Finnish coast on the Bothnian Bay currently fare better in northern Norway than in their home area. The results indicate that the species may not be able to adapt to quickly progressing climate change, which could potentially lead to its extinction.
SpaceX’s satellites will populate the night sky, affecting how we observe the stars. And this is just the beginning of private satellite mega-constellations.
To get a sense of how much carbon the Earth can store, and how it changes over time, scientists would need to count a bewildering number of trees, and track their growth over time. Incredibly, the folks at NASA are now using supercomputers to do precisely that—via top-down imaging from space. Scientists from NASA’s Goddard […]

More than half of bacterial species in the core of the human gut microbiome are potentially sensitive to glyphosate, shows new research. Researchers introduced the first bioinformatics resource to determine and test the potential sensitivity of organisms to glyphosate.
When food is scarce, monarch butterfly caterpillars go from docile to domineering. The results look something like a combination of boxing and ‘bumper’ cars. The less food, the more likely caterpillars were to try to head-butt each other out of the way to get their fill, lunging and knocking aside other caterpillars to ensure their own survival. And, they are most aggressive right before the final stages of their metamorphosis.
Heartbreaking news. After 57 years as a world-class resource for astronomy, the iconic Arecibo telescope is to be decommissioned, or withdrawn from service, the NSF announced today. The dish-type radio telescope – built into a natural depression in the landscape in Puerto Rico – appears to be headed for a “controlled disassembly.”
