A team of scientists at the MRC Laboratory of Medical Sciences (LMS) has uncovered a previously unknown mechanism that controls how genes are switched ‘on’ and ‘off’ during embryonic development.

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ago, when viruses inserted their genetic material into our ancestors' ...

Our ancient past isn't always buried history. When it comes to our DNA, nearly 9% of the human genome is made up of leftover genetic material from ancient viruses (called endogenous retroviruses or ...

All cells contain the same DNA but must turn specific genes ‘on’ and ‘off’ – a process known as gene expression – to create different body parts. The cells in your eyes and arms harbour the same genes ...

Scientists at the MRC Laboratory of Medical Sciences (LMS) have discovered a DNA-based “dimmer switch” that regulates the activity of a critical developmental gene, Cdx2. This work could pave the way ...

Ancient viruses are embedded everywhere in the human genome. Estimates range, but it's thought that about eight percent of the human genome could be made up of these ancient retroviruses, which are ...

A small tissue fold in fly embryos, once thought purposeless, plays a vital role in stabilizing tissues. Researchers show that it absorbs stress during early development, and its position and timing ...

What if you could screen embryos for diseases before they became babies? What if you had the power to choose the traits your baby would have? Would you use it? These practically polar opposite ...

Managing patient expectations in embryo diagnostics during in vitro fertilization requires a careful balance of empathy, ...
