Recombination most often occurs on the COVID-19 phylogenetic tree in the form of 'long branches'

An analysis of millions of SARS-CoV-2 genomes finds that recombination of the virus is uncommon, but when it occurs, it is most often in the spike protein region, the area which allows the virus to attach to and infect host cells.

Assessing immunization capacity of vaccine platforms with DNA origami harboring SARS-CoV-2 receptor binding domain

Researchers demonstrated that vaccine frameworks containing deoxyribonucleic acid (DNA) origami possessing SARS-CoV-2 receptor-binding domain induce strong protective immunity.

Baboons at Amboseli offer clues to the costs of the hybridization, study says

New genetic analyses of wild baboons in southern Kenya reveals that most of them carry traces of hybridization in their DNA. As a result of interbreeding, about a third of their genetic makeup consists of genes from another, closely-related species.

Research highlights the crucial role of other living primates as models for understanding human evolution

A new study based in Africa reveals hidden selection against interspecies breeding in wild baboon species in a strikingly similar way to what has been described for archaic hominins. The findings, based on coupled genomic and long-term field data, highlight the crucial role of other living primates as models for understanding human evolution, particularly for phenomena that are impossible to study in our lineage alone.
