Article Synopsis
- Ectoparasite loads in birds, particularly American Kestrels in Puerto Rico, might be influenced by climate, and a study was conducted to assess this during March-May 2024.
- The research aimed to compare lice prevalence on kestrels in Puerto Rico with data from kestrels in the Bahamas and Utah, finding two new lice species in Puerto Rico that were also present in the Bahamas, but fewer lice in arid Utah.
- Additionally, two species of hippoboscid flies were collected, with implications for the health of kestrels, as these parasites can cause anemia and possibly transmit other parasites.
Centromere Landscapes Resolved from Hundreds of Human Genomes.
Genomics Proteomics Bioinformatics
December 2024
High-fidelity (HiFi) sequencing has facilitated the assembly and analysis of the most repetitive region of the genome, the centromere. Nevertheless, our current understanding of human centromeres is based on a relatively small number of telomere-to-telomere assemblies, which have not yet captured its full diversity. In this study, we investigated the genomic diversity of human centromere higher order repeats (HORs) via both HiFi reads and haplotype-resolved assemblies from hundreds of samples drawn from ongoing pangenome-sequencing projects and reprocessed them via a novel HOR annotation pipeline, HiCAT-human.

Proc Natl Acad Sci U S A
October 2024
Increasing heatwaves are threatening forest ecosystems globally. Leaf thermal regulation and tolerance are important for plant survival during heatwaves, though the interaction between these processes and water availability is unclear. Genotypes of the widely distributed foundation tree species were studied in a controlled common garden during a record summer heatwave-where air temperature exceeded 48 °C.

- Recent studies on single-cell data have helped scientists learn more about sperm production and reasons why some men struggle with infertility.
- The research also suggests that there are links between how testes and brains develop, with both having similar processes for creating cells.
- The text proposes that some mutations in sperm cells may help explain how the brain has grown bigger in mammals during evolution.
