Long-term cognitive effects of COVID-19 studied with repeated neuropsychological testing.

COVID-19 has a wide range of clinical manifestations. Apart from respiratory symptoms, neurological manifestations and cognitive impairment are commonly seen. Due to lack of a clear consensus on the definition of long COVID a pragmatic approach of assessing change from neurological baseline has become prevalent.

Comparative genome sequencing of Drosophila pseudoobscura: chromosomal, gene, and cis-element evolution.

We have sequenced the genome of a second Drosophila species, Drosophila pseudoobscura, and compared this to the genome sequence of Drosophila melanogaster, a primary model organism. Throughout evolution the vast majority of Drosophila genes have remained on the same chromosome arm, but within each arm gene order has been extensively reshuffled, leading to a minimum of 921 syntenic blocks shared between the species. A repetitive sequence is found in the D.
