Treatment for the most common inherited cause of blindness, retinitis pigmentosa, is one step closer, according to investigators at the Research Institute of the McGill University Health Centre (MUHC). They are the first to link two new gene mutations in two French-Canadian families to loss of vision in humans. Their findings are published in this months issue of the American Journal of Ophthalmology. This project was funded by the Canadian Institutes of Health Research (CIHR), le Fonds de la recherche en santé du Québec (FRSQ) and the Foundation Fighting Blindness - Canada.
Approximately 1.5 million people worldwide are affected by retinitis pigmentosa, which at the moment has no cure. This disease causes vision loss by progressive degeneration and death of the cells that make up the retina, the portion of the eye that responds to light.
"Retinitis pigmentosa is a devastating and complex disease," says principal investigator, Dr. Robert Koenekoop, director of pediatric ophthalmology at the Montreal Children’s Hospital of the MUHC. “Many genes, gene mutations and symptoms are involved. The first steps to developing a treatment are the characterization of all these factors. Important progress has been made by identifying two important gene mutations present in the French-Canadian population.”

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
