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

FEBS 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.

Dewey, Second Nature, Social Criticism, and the Hegelian Heritage [PDF]

, 2017
Dewey’s notion of second nature is strictly connected with that of habit. I reconstruct the Hegelian heritage of this model and argue that habit qua second nature is understood by Dewey as a something which encompasses both the subjective and the ...

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Habituation as optimal filtering

iScience
Summary: Habituation, the reduction of responding to repetitive stimuli, is often conceptualized as a kind of attentional filter, amplifying salient signals at the expense of non-salient signals.

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

FEBS 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 ...

Presence of Mind: A Political Posture [PDF]

, 2012
The political posture often encouraged in liberatory movements is that of urgency. Urgency is based on the idea that if oppressed peoples do not act “now,” then their fate is forever sealed as subordinates within social and political power hierarchies ...

Organoids in pediatric cancer research

FEBS 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.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

American Black Bear–Apiary Conflicts in Michigan

Human-Wildlife Interactions, 2017
American black bear (Ursus americanus) damage to apiaries can result in substantial economic loss. We used records of black–bear apiary conflicts collected by the Michigan Department of Natural Resources to characterize damage in the Upper and Northern ...

Processing of the Arousal of Subliminal and Supraliminal Emotional Stimuli by the Human Amygdala [PDF]

, 2003
The amygdala is known to play an important role in conscious and unconscious processing of emotional and highly arousing stimuli. Neuroanatomical evidence suggests that the amygdala participates in the control of autonomic responses, such as skin ...
