Scientists uncover mystery of DNA methylation

All species mark their DNA with methyl groups. This is done to regulate gene expression, distinguish indigenous DNA from foreign DNA, or to mark old DNA strands during replication. Methylation is carried out by certain enzymes ...

Plants defend their territory with toxic substances

Plants are stakeholders in a subtle and complex chemical warfare to secure optimal growth conditions. Although it has been known for decades that plants produce and release chemical substances to fight their neighbors, it ...

Male and female mice have different brain cells

Caltech researchers have discovered rare brain cell types that are unique to male mice and other types that are unique to female mice. These sex-specific cells were found in a region of the brain that governs both aggression ...

Evolution used same genetic formula to turn animals monogamous

Why are some animals committed to their mates and others are not? According to a new study led by researchers at The University of Texas at Austin that looked at 10 species of vertebrates, evolution used a kind of universal ...

Drivers of evolution hidden in plain sight

Research led by the European Bioinformatics Institute (EMBL-EBI) and the University of Washington has shown that the biological diversity needed for evolution can be generated by changes in protein modifications. The findings, ...

Biologists show how plants turn off genes they don't need

A plant has one genome, a specific sequence of millions of basepairs of nucleotides. Yet how this genome is expressed can vary from cell to cell, and it can change as a plant goes through various life stages, from germination ...
