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).

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
