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 ...

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 ...

MPN-BP transformation is driven by sequential mutations disrupting genomic stability, with TP53 mutations being strong predictors of progression. TP53 mutations confer a selective growth advantage, ...

Many scientific discoveries are serendipitous—the result of chance. Seeing evolution in action in a cheese cave turned out to be exactly that for Benjamin Wolfe, associate professor of biology, and ...

Much of the phenotypic variation that is observed within and between species is the result of differences in gene regulation: specifically when, where and how much the genes are expressed. Given the ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

Cucumber is an economically important crop worldwide, ranking as the third most-produced vegetable after tomatoes and onions.

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

Scientists have uncovered an unexpected genetic shift that may explain how animals with backbones first emerged and became so diverse.

Marek’s disease can be pervasive in chicken houses. Chickens infected by this highly contagious viral disease often develop tumors, become paralyzed and die. They can shed the virus through their skin ...

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 ...
