Ability to make pheomelanin, the orange-red pigment responsible for human red hair and bird red feathers, helps remove excess cysteine and can reduce oxidative stress. phys.org/news/2026-01...
Orange pigments in birds and human redheads prevent cellular damage, study shows
A pigment that makes feathers and hair orange helps prevent cellular damage by removing excess cysteine from cells. Pheomelanin is an orange-to-red pigment that is built with the amino acid cysteine a...

Bioinformatics isn’t just running pipelines.
The hardest part? Knowing when not to code.

#Bioinformatics students, want to learn Linux and still have your old computer? Install Ubuntu on it. Linux has many versions ("distributions") and Ubuntu is a common one with lots of online support. Use your old computer, the one you replaced because it got really slow, but still KIND OF works.

This preprint used RNA-seq to see how sample size affects reproducibility. They found increasing sample sizes improves precision more than recall. "False negatives (low recall) are a more significant driver of low replicability than false positives (low precision)". journals.plos.org/ploscompbiol...
Replicability of bulk RNA-Seq differential expression and enrichment analysis results for small cohort sizes
Author summary Transcriptomics data from RNA sequencing (RNA-Seq) experiments are complex and challenging to analyze due to their high dimensionality and variability. These experiments often involve l...

Hey folks! I got a tattoo of my beloved PIEZO ion channel on my arm! Now I can show how they activate (flatten) under pressure by flexing—Will add a bit of performance art to my science talks 🧪🧠.

Measles vaccine & asthma study found that children who have OR WILL LATER DEVELOP asthma show a faster drop in measles antibodies, compared to children who don't develop asthma. Study of 838 children by Yoo et al 2015. pmc.ncbi.nlm.nih.gov/articles/PMC...
Asthma Status and Waning of Measles Antibody Concentrations after Measles Immunization
Asthmatics have increased risks of common and serious microbial infections including vaccine preventable diseases. Little is known about whether asthma influences waning of humoral immunity. We assess...

SSRI fluoxetine (Prozac) increases blood levels of anti-inflammatory cytokine IL-10. This is why fluoxetine helps protect against overactive immune responses that can lead to sepsis or long Covid. Paper: www.science.org/doi/10.1126/...
Fluoxetine promotes IL-10–dependent metabolic defenses to protect from sepsis-induced lethality
