A single genetic test that is capable of detecting all mutations involved in the development of cystic fibrosis could be just a few years away, the 20th annual conference of the European Society of Human Reproduction and Embryology heard today (Monday 28 June).
Researchers at Monash University in Melbourne, Australia, have discovered that recently developed microarray (or gene chip) technology* can be used successfully to detect one of the commonest cystic fibrosis (CF) genetic mutations with 100% accuracy.
This means that, once the technology has been refined, gene chips could be used to detect all CF mutations in a single, quick and easy test that would produce almost immediate results. The analysis could be carried out on embryos during preimplantation genetic diagnosis (PGD), so that only healthy embryos would be transferred to the woman. The technology could be used during PGD for other genetic diseases too.

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
