Robust and efficient software for reference-free genomic diversity analysis of GBS data on diploid and polyploid species.

Mol Ecol Resour 2021 Jul 20. Epub 2021 Jul 20.

Department of Systems and Computing Engineering, Universidad de los Andes, Bogotá, Colombia.

Genotyping-by-Sequencing (GBS) is a widely used and cost-effective technique for obtaining large numbers of genetic markers from populations by sequencing regions adjacent to restriction cut sites. Although a standard reference-based pipeline can be followed to analyze GBS reads, a reference genome is still not available for a large number of species. Hence, reference-free approaches are required to generate the genetic variability information that can be obtained from a GBS experiment. Read More

Machine learning identifies novel markers predicting functional decline in older adults.

Brain Commun 2021 Jul 26;3(3):fcab140. Epub 2021 Jun 26.

Department of Psychology, The Ohio State University, Columbus, OH 43210, USA.

The ability to carry out instrumental activities of daily living, such as paying bills, remembering appointments and shopping alone decreases with age, yet there are remarkable individual differences in the rate of decline among older adults. Understanding variables associated with a decline in instrumental activities of daily living is critical to providing appropriate intervention to prolong independence. Prior research suggests that cognitive measures, neuroimaging and fluid-based biomarkers predict functional decline. Read More
