SOURCE: SCIENCE DAILY PSYCHOLOGY FEEDTITLE: APOE2 may protect the brain from Alzheimer’s and aging
URL: https://www.sciencedaily.com/releases/2026/07/260723084856.htm
The longevity-linked APOE2 gene appears to protect brain cells by reducing DNA damage and helping neurons recover from stress. The finding could open a new path toward treatments that mimic APOE2’s defenses in people at higher genetic risk for Alzheimer’s.

Thrilled to see our work featured on the cover of Molecular Cell.
The image: an electron micrograph of an i-loop, the DNA structure we propose as a source of eccDNA formation. Almost like catching circular DNA formation in the act.

Huge congratulations to @EZ_eta for leading the experimental work, and a big thank you to our collaborators at IIT for their Nanopore expertise, as well as to Michele Giannattasio head of the EM on Single Molecules Facility for his contribution to the structural analysis.

How do cancer-associated extrachromosomal circular DNAs arise?
In our new manuscript, we show that single-strand DNA damage in repetitive sequences can trigger i-loop formation and eccDNA generation. What started at telomeres may reflect a much broader principle across the genome and help explain how ecDNA may emerge in cancer.

Genetic and ecological studies of animals in #Chernobyl and #Fukushima
by Timothy A Mousseau, Anders P Møller
2014 Sep-Oct
"Recent advances in genetic and ecological studies of wild animal populations in Chernobyl and Fukushima have demonstrated significant genetic, physiological, developmental, and fitness effects stemming from exposure to #radioactive contaminants. The few genetic studies that have been conducted in Chernobyl generally show elevated rates of #GeneticDamage and #Mutation rates. All major taxonomic groups investigated (i.e., #birds, #bees, #butterflies, #grasshoppers, #dragonflies, #spiders, #mammals) displayed reduced population sizes in highly radioactive parts of the #ChernobylExclusionZone. In #Fukushima, population censuses of birds, butterflies, and #cicadas suggested that abundances were negatively impacted by exposure to radioactive contaminants, while other groups (e.g., dragonflies, grasshoppers, bees, spiders) showed no significant declines, at least during the first summer following the disaster.
"Insufficient information exists for groups other than insects and birds to assess effects on life history at this time. The differences observed between Fukushima and Chernobyl may reflect the different times of exposure and the significance of multigenerational mutation accumulation in Chernobyl compared to Fukushima. There was considerable variation among taxa in their apparent sensitivity to radiation and this reflects in part life history, physiology, behavior, and evolutionary history. Interestingly, for birds, population declines in Chernobyl can be predicted by historical mitochondrial #DNA base-pair substitution rates that may reflect intrinsic #DNARepair ability."
