But in fact, fly immunity is highly reproducible! 🎊 ~80% of claims could be verified. Moreover, some challenged claims just reflect the field advancing its knowledge/tools. The lesson: if the tools are good and the research largely exempt from direct translation pressures, science works. 3.5/n
A chart depicting the track of claims into verified, unchallenged, challenged, partially verified, or mixed.

Figure 1: Flow of the study.
Claims were first classified in five categories based on literature. 45 unchallenged claims were selected to be experimentally tested and
classified either as challenged or as verified. We further classify some unchallenged as consistent or inconsistent depending on their
consistency with current knowledge.

Journals Operating Predatory Practices Are Systematically Eroding the Science Ethos: A Gate and Code Strategy to Minimise Their Operating Space and Restore Research Best Practice
Scientific research seeks to extend knowledge and understanding, an activity that perhaps more than any other advances society and humanity. In essence, it is the search for truth. But, because it se....

Various vibrios can colonise a large vacuole called VCV (Vibrio-containing-vacuole) within Paramoeba atlantica. The VCVs acidify and the vibrios multiply and remain alive inside the VCVs for hours. T...

Problematic Paper Screener: Trawling for fraud in the scientific literature
Science sleuths are stepping up efforts to detect bogus science papers. This includes building tools that comb through millions of journal articles for signs of tortured phrases spawned by AI.

Frequent Q is how mirror bacterium could persist in nature. Marine Prochlorococcus good example. Little downside in terms of competitiveness + resistant to protists and phages. Net positive growth allows invasion. See Chapter 8 of technical report here: purl.stanford.edu/cv716pj4036
Figure 8.2 from technical report on mirror bacteria, showing potential for net population growth and invasion of marine environment by mirror phototrophic bacteria.

Important piece by Gittleman - “It’s impossible to separate human health from health of the natural world. Ecology is the unifying science that integrates knowledge..[the] One Health approach is unlimited, exciting, & necessary for the health of life on our planet” www.pnas.org/doi/10.1073/... 🧪🌎🌐🌾
Photo of the front page of the paper - showing animals and plants and people encircled across the globe - There needs to be more emphasis on the ecological component of One Health as we consider the problems of biodiversity loss, climate extremes, habitat fragmentation, and emerging disease.

Plasmid afficionados: Does anybody know of any chromosomal genes that are required for plasmid conjugation? We have found a few by chance in a recent experiment and I would be really interested to know if there are other examples. #microsky #plasmid
