Repetitive elements shape embryonic chromatin landscape

Retrotransposons are repetitive elements that form almost half of the mammalian genome. Even though they are so common, they have previously been considered to be fairly insignificant. Together with colleagues from the USA, ...

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 ...

Scientists invent new tool for the synthetic biologist's toolbox

Researchers at the University of California San Diego have invented a new method for controlling gene expression across bacterial colonies. The method involves engineering dynamic DNA copy number changes in a synchronized ...

Large study uncovers genes linked to intelligence

Exactly what constitutes intelligence, and to what extent it is genetic, are some of the most controversial questions in science. But now a new study of nearly 80,000 people, published in Nature Genetics, has managed to identify ...

Finding a new major gene expression regulator in fungi

Just four letters—A, C, T, and G—make up an organism's genetic code. Changing a single letter, or base, can lead to changes in protein structures and functions, impacting an organism's traits. In addition, though, subtler ...
