Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Tungsten in biological systems [PDF]

open access: yesFEMS Microbiology Reviews, 1996
Tungsten (atomic number 74) and the chemically analogous and very similar metal molybdenum (atomic number 42) are minor yet equally abundant elements on this planet. The essential role of molybdenum in biology has been known for decades and molybdoenzymes are ubiquitous.

Expansion sequencing: Spatially precise in situ transcriptomics in intact biological systems

open access: yesScience, 2020
Identifying transcript location in cells Identifying where specific RNAs occur within a cell or tissue has been limited by technology and imaging capabilities. Expansion microscopy has allowed for better visualization of small structures by expanding the

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

The Immune System [PDF]

open access: yes, 1995
Modern biotherapy has been in use for some 30 years. The first types of biotherapy were nonspecific stimulators of the immune response, but advances in genetic engineering are allowing the mass production of pure biological products which are now being ...

Controlling a mobile robot with a biological brain [PDF]

open access: yes, 2010
The intelligent controlling mechanism of a typical mobile robot is usually a computer system. Some recent research is ongoing in which biological neurons are being cultured and trained to act as the brain of an interactive real world robot thereby either

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.
