Babraham Institute scientists have identified chromosome ‘loops’ which have implications for healthy growth of babies in the womb. Disruption of these loops can lead to Beckwith-Wiedemann Syndrome (BWS) – over-large babies with various tumours – which affects 1 in 13,000 births. The risk of developing the syndrome is increased four-fold in babies born following IVF treatment.
Confirmation of the existence of the loops, described in an article published in Nature Genetics, was made by Dr Adele Murrell and colleagues, working with Dr Wolf Reik at the Babraham Institute. Scientists had previously speculated that these loops, or something similar, exist, but no-one had evidence to prove this was the case.
Dr Reik’s group studies imprinted genes, which are genes in mammals that are only expressed from one of the parental chromosomes. These genes have important roles in regulating the growth of the baby in the womb and its adaptations to life outside the womb. Many of them occur in clusters, and share elements by which their expression can be increased (enhancers) or decreased (silencers).

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
