Study Links Individual Differences in Flicker Perception to Attentional Blink Magnitude
A preprint study of 84 individuals found that critical flicker fusion (CFF) thresholds — a measure of the visual system's temporal resolution — predicted the magnitude of the attentional blink, a well-known gap in visual awareness. No link was found between CFF and global motion sensitivity in a separate sample of 79 individuals. The findings suggest CFF reflects a broader visual processing rate that influences complex perceptual tasks beyond simple flicker detection.
Researchers tested whether individual differences in critical flicker fusion (CFF) thresholds — the highest frequency at which a flickering light appears to flash rather than appear steady — reflect a general visual processing rate or are limited to stimulus-specific perception. In a non-clinical sample of 84 participants, higher CFF thresholds were associated with smaller attentional blink magnitudes, meaning individuals with faster temporal resolution were better able to detect a second target presented shortly after a first in a rapid visual stream. However, in a separate sample of 79 individuals, no relationship was found between CFF and global motion sensitivity, suggesting the link is not universal across all temporally dependent visual tasks. The dissociation between these two findings implies that CFF may capture a processing rate relevant to attention-based temporal tasks but not to lower-level motion integration. The study was posted as a preprint on bioRxiv and has not yet undergone peer review.
What's missing
The study has not yet been peer-reviewed, as it is a bioRxiv preprint. The mechanism linking CFF to attentional blink performance is not established, and it remains unclear whether the null result for global motion reflects a true dissociation or insufficient statistical power.

Gut Bacteria Enzyme Found to Break Down Heat-Processed Food Compounds, Producing Novel Biogenic Amines
Researchers have discovered that an enzyme in common gut bacteria can degrade N-epsilon-carboxymethyllysine (CML), a compound formed during thermal food processing, producing previously unknown biogenic amines. The enzyme, ornithine decarboxylase SpeC from enterobacteria, acts on CML and related modified lysine derivatives through a low-level 'underground' catalytic activity. This finding suggests a previously unrecognized communication axis between thermally processed dietary compounds and gut microbial physiology, with potential implications for host health.
Full-Length Gene Sequencing Reveals Two Distinct Bacterial Communities in Black-Legged Ticks Expanding Into Canada
Researchers used Oxford Nanopore full-length 16S rRNA gene sequencing to characterize the microbiome of Ixodes scapularis black-legged ticks collected in Nova Scotia, Canada, distinguishing between tick-adapted bacteria and environmentally acquired bacteria. The study comes as I. scapularis — the primary vector of Lyme disease — is rapidly expanding northward into Canada due to climate change. The findings suggest that environmentally derived bacteria in tick microbiomes are not mere contamination, which has implications for how tick microbiome data is collected and interpreted across surveillance studies.
Study Identifies Metabolic Link Between Cell Envelope Stress and Biofilm Formation in Bacteria
Researchers have discovered that the metabolite acetyl-CoA directly inhibits enzymes that degrade the bacterial signaling molecule c-di-GMP, connecting cell envelope biosynthesis stress to biofilm formation in Pseudomonas aeruginosa. The study found that sub-inhibitory concentrations of antibiotics targeting early peptidoglycan biosynthesis — but not other antibiotic classes — elevate c-di-GMP levels by reducing phosphodiesterase activity, with acetyl-CoA competing for the enzyme active site. Because the relevant enzyme domain is broadly conserved across bacterial species, this checkpoint mechanism may be widespread and could have implications for understanding antibiotic-induced biofilm responses.
