An Unexpected Facet of Extremophiles: Their Aesthetic Potential in Artistic Expression

Microbial Biotechnology, Volume 18, Issue 10, October 2025.
In an era marked by environmental challenges and the proliferation of misinformation, the fusion of art and science is a strategy to promote public understanding and appreciation of complex scientific phenomena. We illustrate how the use of extremophiles offers novel avenues for artistic exploration and emphasise the benefits of such interdisciplinary ...

Periplasmic Proteins of the Extremophile Acidithiobacillus ferrooxidans [PDF]

Molecular & Cellular Proteomics, 2007
Acidithiobacillus ferrooxidans is a chemolithoautotrophic acidophile capable of obtaining energy by oxidizing ferrous iron or sulfur compounds such as metal sulfides. Some of the proteins involved in these oxidations have been described as forming part of the periplasm of this extremophile.

Fast pH‐Driven Solubilization Method of Realgar (As4S4) to Reduce the Toxicity of Arsenic [As(III)] for Medicinal Purposes

Advanced Science, Volume 12, Issue 29, August 7, 2025.
Arsenic trioxide transformed acute promyelocytic leukemia therapy and shows promise against HIV. A new method to solubilize the mineral realgar produces different arsenic species depleting the main arsenic target, nuclear PML protein, and retaining effects on leukemic and HIV reservoir cells, while minimizing off‐target damage.
