- Reposted by Andi FischerSuper excited to have this paper out. We developed a complex set of ground truth samples to test more than 110 statistical approaches for differential #metaproteomics We can now give clear guidance on what tests perform well. Thank you Tjorven Hinzke and @benoitkunath.bsky.social for the leadership
- Reposted by Andi FischerThis is such an important, rigorous, and beautiful paper by Rochelle - light pollution impacts both the "normal" visual cues of detecting sunset to trigger activity AND the polarised visual cues of the sky used for navigation...in two completely different animal species! 🦋🕷️🌌 Such amazing work!
- Multiple anthropogenic stressors can negatively impact species but can a single stressor also have multiple, concurrent impacts? Here we show that light pollution creates several simultaneous impacts to the nocturnal movement ecology of a moth and a spider: tinyurl.com/5eku5bff (1/5)
- Reposted by Andi FischerBeen saying this for a while that LLMs can't create new scientific knowledge simply because they use a predictive model. This paper by Chinese and American researchers shows this limitation of LLMs. Good for brainstorming research questions and hypotheses, but can't create new knowledge.
