A genome study links outdoor air pollution to DNA mutations associated with lung cancer in non-smokers, suggesting pollution may contribute to rising lung cancer cases among those who have never smoked, with higher pollution exposure correlating with more mutations.
The largest-ever study of bird genomes has revealed a clear picture of the bird family tree, identifying fundamental relationships among major groups of living birds and overturning some previous ideas about bird relationships. The study also unveiled a new grouping of birds called "Elementaves" and confirmed a close relationship between passerines and parrots. Additionally, the study placed a timescale on the bird family tree, showing that most groups of modern birds emerged within a few million years after the extinction of dinosaurs. However, one branch of the bird family tree, the hoatzin, remains a mystery despite the extensive genome data analysis.
A genome study by researchers at Yale and the Broad Institute of MIT and Harvard has found that deletions in the human genome compared to other primates have played a significant role in human evolution. While previous studies have focused on additions and insertions, this study highlights the importance of deletions in shaping the human genome.
Retinal scans of the fundus can help doctors track human aging in a non-invasive, less expensive, and more accurate way than other aging clocks currently available. The microvasculature in the retina may be a reliable indicator of the overall health of the body’s circulatory system and brain. Researchers have trained and tuned the model for eyeAge using the well-studied EyePACS data set that involved over 100,000 patients, and then applied it to more than 64,000 patients from the UK Biobank. The study also performed a genome-wide association study (GWAS) to establish the genetic basis for this “clock,” which they call eyeAge.
