For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary ...

The study of experimental evolution in Escherichia coli has provided unprecedented insights into the mechanisms of adaptive mutations, elucidating how populations diverge and optimise their fitness ...

In real life, mutants can arise when their DNA changes to give them an advantage over the rest of the population. A team from ...

Mitochondria are known as the body’s “energy factories,” and their function is essential for life. Inside mitochondria, a set of complexes called the oxidative phosphorylation (OxPhos) system ...

Researchers published a new study, “Ongoing chromothripsis underpins osteosarcoma genome complexity and clonal evolution,” in Cell that they say solves the mystery of what drives the genomic ...

(TP53), widely known as the “guardian of the genome,” is one of the most frequently altered genes in human cancer. While its canonical tumor-suppressive ...

Human aging is not what natural selection failed to prevent. It is what happens when selection simply has nothing left to act ...

Researchers at Scripps have created T7-ORACLE, a powerful new tool that speeds up evolution, allowing scientists to design and improve proteins thousands of times faster than nature. Using engineered ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. Vaccinating birds against bird flu reduces the spread of the disease, but may have unintended consequences. This is the ...
