TL;DR: It is concluded that a sex-biased process that reduced the female effective population size, or an episode of natural selection unusually affecting chromosome X, was associated with the founding of non-African populations.

TL;DR: It is shown that all sampled Austronesian groups harbour ancestry that is more closely related to aboriginal Taiwanese than to any present-day mainland population, suggesting that either there was once a substantial Austro-Asiatic presence in Island Southeast Asia, orAustronesian speakers migrated to and through the mainland, admixing there before continuing to western Indonesia.

TL;DR: In this paper, the authors reported targeted sequencing of 63 known prostate cancer risk regions in a multi-ancestry study of 9,237 men and used the data to explore the contribution of low-frequency variation to disease risk.

TL;DR: Even biplane TEE may have limited use in the precannulation assessment of the aorta for plaque and the detection of distal ascending aortic pathology, according to patients studied during cardiac surgery.

TL;DR: Externally and prospectively trained and validated machine learning models for mortality and critical events for patients with COVID-19 at different time horizons were developed and established model interpretability to identify and rank variables that drive model predictions.
