Pink biofilm formation on stone monuments and mural paintings poses serious harm to cultural heritage preservation. Pink biofilms are globally widespread and recalcitrant to eradication, often causing recurrences after restoration. Yet, the ecological drivers of pink biofilm formation and the metabolic functions sustaining the growth of pigment-producing biodeteriogens remain unclear.

- Wetlands deliver essential ecosystem services, but are increasingly threatened by pollutants, particularly plastics and microplastics (MPs), which have been under-researched in these environments.
- This study examined the abundance of MPs in two common aquatic insect groups collected from twelve Mediterranean wetland zones in Andalusia, exploring how proximity to landfills and the presence of certain waterbirds influenced MP levels.
- Results revealed a total of 571 MPs, mainly blue fibers, with higher contamination near landfills and at sites with landfill-feeding birds; additionally, aquatic insects can be effective indicators in monitoring MP pollution to target conservation efforts.
Could Raman spectroscopy investigate the changes of cell oxidative stress status in thyroid diseases? A pilot study on cytological samples.

Article Synopsis
- * In a study of 28 patients, RS was used to analyze thyroid cytological samples from fine needle aspirations (FNA) to evaluate cell oxidative stress, a major cancer risk factor.
- * The findings categorized patients based on changes in Raman spectra related to oxidative stress and carotenoid presence, suggesting a link between oxidative stress and thyroid diseases that could inform future research on biomarkers.
Article Synopsis
- The study focuses on a resilient Gram-negative bacterium that can survive harsh hospital conditions due to its resistance to dehydration.
- Researchers used μ-Raman spectroscopy and atomic force microscopy (AFM) to assess the bacterium's membrane properties during a 16-week dehydration period, observing that its membranes remained intact despite undergoing structural changes.
- Findings showed a link between changes in the membrane properties and bacterial fitness, suggesting μ-Raman can effectively evaluate bacterial health status nondestructively and efficiently.
The study explores the application of natural biocides (oregano essential oil and eugenol, directly applied in solutions or encapsulated within silica nanocapsules) for safeguarding stone cultural heritage from biodeterioration, using green algae ( sp.) and cyanobacteria ( sp.) as common pioneer biodeteriogens.
