 How one antibiotic dose can reshape your gut microbiome for yearsHow one antibiotic dose can reshape your gut microbiome for years
 
Long-term registry-linked analysis of nearly 15,000 adults shows that antibiotic use is associated with persistent changes in gut microbiome diversity and composition for up to 4–8 years. These effects vary by antibiotic class, with clindamycin, fluoroquinolones, and flucloxacillin showing the strongest and most sustained associations.
 
   Boosting noradrenaline during learning makes the brain link memories more broadly, study findsBoosting noradrenaline during learning makes the brain link memories more broadly, study finds
 
A randomized placebo controlled experiment shows that increasing noradrenaline during learning does not improve basic memory accuracy but increases the spread of associations across the hippocampal cognitive map. This broader neural linking leads to greater overgeneralization errors days later, suggesting that noradrenergic arousal can reshape how related memories become interconnected.

 Genomic sequencing may expand newborn screening beyond biochemical tests
 
Genomic sequencing may expand newborn screening beyond biochemical testsRoutine newborn screening (NBS) has transformed early disease detection. However, traditional biochemical tests limit the range of conditions that can be identified at birth. Next-generation sequencing is being explored as a complementary screening tool.
