Biology has clever ways to mask the effects of potentially harmful gene mutations. Scientists are investigating how this ...
How do cells know what they should become as the body develops? Biological development depends crucially on spatial patterns: the lines that eventually give rise to segments, organs, or markings like ...
As it turns out, beneficial mutations are far more common than a 50-year-old theory predicted, but the world changes too fast ...
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 ...
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 ...
Mutation dynamics in bacterial populations underpin the generation of genetic diversity that drives adaptation, speciation and the emergence of antimicrobial resistance. Spontaneous base substitutions ...
From snow white and jet black to golden brown, domestic chickens display a wider range of plumage colors than almost any ...
Although viruses are known to undergo continual mutation, not all genetic alterations have a significant effect. Sometimes, a ...
As language models learn to interpret words in a sentence, protein language models learn how amino acids work together within a protein. Konstantina Tzavella, who used artificial intelligence in her ...
The domestication of horses is a much more recent even compared to other domesticated species; horses were domesticated about 4,500 years ago, which was about 5,000 years after the domestication of ...
Tobacco smoking is linked to specific genetic mutations in MDS, affecting chromatin modification and RNA splicing pathways. A dose-response relationship exists, with higher smoking intensity ...
In the 1960s, Kimura’s neutral theory revolutionized molecular biology by arguing most DNA changes are random, not adaptive. A new study finds beneficial mutations are far more common than Kimura’s ...
