NIH-funded researchers have identified a gene that appears to be a crucial signal for the beginning of puberty in human beings as well as in mice. Without a functioning copy of the gene, both humans and mice appear to be unable to enter puberty normally. The newly identified gene, known as GPR54, also appears necessary for normal reproductive functioning in human beings.
The study, funded in part by the National Institute of Child Health and Human Development (NICHD), appears in the October 23 issue of the New England Journal of Medicine. GPR54 is located on an autosomal chromosome (a chromosome that is not a sex chromosome). The study also was funded by the National Center for Research Resources and the National Institute of General Medical Sciences, both at NIH.
"The discovery of GPR54 is an important step in understanding the elaborate sequence of events needed for normal sexual maturation," said Duane Alexander, M.D., Director of the National Institute of Child Health and Human Development (NICHD). "Findings from this study may lead not only to more effective treatments for individuals who fail to enter puberty normally, but may provide insight into the causes of other reproductive disorders as well."

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...
