The evolutionary network of whiptail lizards reveals predictable results of crossbreeding

Abstracts of mixed species in monosexual whiptail lizards. Primary hybridization (i.e., a hybridization event between two diploid sexes associated with the transition to diploid reproduction) precedes addition of the genome (i.e. petiole height) (left). The sexual types associated with each process are indicated. Colored bars in the structure diagram (each representing data on a single … Read more

British researchers believe that somatic mutations play a vital role in aging, longevity and death

Understanding why some mutations impair normal body functions and contribute to cancer may lead to new clinical laboratory diagnoses. New insight into human genes It may help explain the aging process and provide clues to improving human longevity that could be useful to clinical laboratories and researchers developing cancer diagnoses. A recent study conducted in … Read more

Giant Daisies and Darwin’s Evolution

Newswise – Naturalists Alfred Russel Wallace and Charles Darwin both introduced the theory of evolution at the same time in 1858. They thus changed the course of biology and how we understand the natural world around us. Evolution is about how species change over time with the help of genetics, but also about how new … Read more

The genetics does not differ between two types of birds, despite the great difference in plumage

Written by Jessen Steiner, Museum für Naturkunde – Leibniz-Institut für Evolutions- und Biodiversitätsforschung Population structure. Gray and maroon correspond to the wood of the masked swallow and white, respectively. Species assignment is done purely by feathers. (a) A somatic network resulting from uncorrected pairwise distances between individuals. (b) Z chromosome network resulting from uncorrected pairwise … Read more

Genetic analysis of highly virulent Klebsiella pneumoniae reveals possible genetic markers for differentiation from classical strains.

Dataset properties We analyzed 79 hvKp isolates identified as isolates from patients’ livers. They were collected in China (n = 39), Singapore (n = 26), USA (n = 8), Brazil (n = 2) and one sample each from Ecuador, Guadeloupe, South Korea, and Vietnam (Table 1). Among the 36 types of sequences (STs) present in … Read more

The study aims to understand how female fertility is determined at the molecular level

Fertility is limited to female mammals. From birth, females possess a limited number of primordial follicles, which are collectively called the ovarian reserve. Inside each follicle is an egg that eventually turns into an egg. But with age, the follicles in the ovarian reserve decrease. Despite their fundamental importance, our understanding of how ovarian reserve … Read more

New CRISPR treatment enters human trial

Cardiovascular disease is the number one cause of death in the world. High cholesterol is a modifiable risk factor for heart-related diseases. Biotech company Verve Therapeutics recently launched a human clinical trial of a gene-editing drug intended to lower cholesterol. Cardiovascular disease is the number one cause of death worldwide. In 2019, about 17.9 million … Read more
