A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

In a recent study published in Nature Genetics, researchers performed an allelic-level single-cellular multi-omics evaluation of hematopoietic stem/progenitor cells (HSPCs) obtained from individuals ...

(Memphis, Tenn.—July 28, 2023) The influenza (flu) virus is constantly undergoing a process of evolution and adaptation through acquiring new mutations. Scientists at St. Jude Children’s Research ...

A groundbreaking study published in this week’s issue of PNAS by scientists from Israel and Ghana shows that an evolutionarily significant mutation in the human APOL1 gene arises not randomly but more ...

The stability of ribonucleoprotein complexes of SARS-CoV-2 nucleocapsid proteins differs among variants of concern and the viral evolution of nucleocapsid protein can be understood in the framework of ...

The analysis revealed that about 2 per cent of sperm from men in their early 30s contained disease-causing mutations. That ...

In a recent study published in the bioRxiv* preprint server, researchers analyzed the characteristics of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) Omicron subvariants BA.4, BA.5, ...

Geneticists have sought to understand the impact of genetic mutations, and what drives and maintains changes in DNA. Researchers have now reconstructed the evolution of a set of genes, and the ...

Researchers discover that insect sex systems influence the speed of mitochondrial evolution, impacting biodiversity tracking ...
