A team of New York University biologists has uncovered a previously unknown role for a set of cells within the female reproductive tract of fruit flies that affects the functioning of sperm and hence fertility. Their discovery, which is published November 8 in the online, open-access journal PloS Biology, adds to our understanding of how insects reproduce and may provide a means to manipulate reproductive behavior in other insects. The researchers studied spermathecal secretory cells...

A new study has shed light on the process by which fruit flies develop with their body proportions remaining constant. The study, conducted by the research group of Professor Markus Affolter at the Biozentrum of the University of Basel and Sven Bergmann's group at the Department of Medical Genetics, University of Lausanne, has demonstrated that the morphogen Dpp and the feedback regulator Pentagone are key factors responsible for proportional tissue growth in wings of a fruit fly. This...

Researchers Find First Human From Primate Gene Split In Brain

A new analysis has found that the first genes which appeared after the primate branch split are more likely to be expressed in the developing human brain. Researchers believe that evolutionary recent genes may be responsible for constructing the uniquely powerful human brain. "We found that there is a correlation between new gene origination and the evolution of the brain," senior author Manyuan Long, PhD, Professor of Ecology & Evolution at the University of Chicago, wrote in the...

A study into the muscle development of several different fish has given insights into the genetic leap that set the scene for the evolution of hind legs in terrestrial animals. This innovation gave rise to the tetrapods–four-legged creatures, and our distant ancestors–that made the first small steps on land some 400 million years ago. A team of Australian scientists led by Professor Peter Currie, of the Australian Regenerative Medicine Institute at Monash University, and Dr...

(Ivanhoe Newswire) -- Ovarian tumors can be deadly - especially if gone undetected like so many are. A new study, published in the September 20 issue of PLoS Biology, may shed light on how these deadly tumors develop and spread. Stanford researchers, including Patrick O. Brown, senior author of the study and Howard Hughes Medical Institute investigator, were specifically looking for evidence that an ovarian tumor had rearranged its DNA so that two distinct genes were now fused together....

Researchers studying ovarian cancer have discovered that, in a substantial fraction of ovarian tumors, a gene closely related to the estrogen receptor is broken and fused to an adjacent gene by a chromosome rearrangement; a finding that could shed light on how these deadly tumors develop and spread. Identifying a gene fusion in ovarian cancer may provide scientists with a new opportunity to specifically identify ovarian cancers early in their development and perhaps to develop new treatments....

A study in worms that are less than a millimetre long has yielded clues that may be important for understanding how nerves grow. A team of researchers from the Queensland Brain Institute (QBI) has probed the molecular mechanisms which prompt the development of dendrites, in the nematode Caenorhabditis elegans. The findings are published September 20 in the online, open access journal PLoS Biology. Dendrites are the branch-like structures in nerve cells, which receive electrochemical...

About 15 percent of cases of an aggressive, difficult-to-detect form of ovarian cancer contain a unique fusion between two neighboring, normally separate genes, say researchers at the Stanford University School of Medicine. Although gene fusions are known to occur in prostate and some blood cancers, they have been notoriously difficult to identify in solid tumors. This is the first recurrent gene fusion found for ovarian cancer. The finding is important because it could give clinicians an...

Research Disputes Established Theory on Chromosome Activity Fruit flies have been indispensible to our understanding of genetics and biological processes in all animals, including humans. Yet, despite being one of the most studied of animals, scientists are still finding the fruit fly to be capable of surprises, as evidenced by new research at the University of Rochester. The latest revelation has to do with the activity of the X chromosome in male fruit flies. It was widely accepted...

Scientists reveal how a type of white blood cells, called Natural Killer cells, protect the body from tumors and virus-infected cells Scientists reveal in more detail than ever before how white blood cells kill diseased tissue using deadly granules, in research published today in PLoS Biology. The researchers, from Imperial College London and the University of Oxford, used 'optical' laser tweezers and a super-resolution microscope to see the inner workings of white blood cells at the...

PLoS ONE is an open-access peer-reviewed scientific journal published by the Public Library of Science (PLoS). It was established in 2006 as a beta version. In August 2008 it moved from a weekly publication schedule to a daily one, publishing articles as soon as they became ready. In October 2008, it came out of “beta.” In September 2009, PLoS ONE made full online usage of every published article publicly available. The founding managing editor was Chris Surridge. He was succeeded by...
