Male and female of the beautiful demoiselle (Calopteryx virgo) in the so-called "mating wheel".
Traditionally, the evolutionary development of an insect species has been explained by the notion that the female insect chooses her male partner based on size and other factors, so-called assortative mating. These mating patterns have also been believed to partially explain how the isolation between different species is maintained.

Scientists at the University of Massachusetts Medical School (UMMS) have performed the first CRISPR/Cas9 screen to discover human proteins that Zika virus needs for replication. This work, led by Abraham Brass, MD, PhD, assistant professor in microbiology & physiological systems, reveals new leads that may be useful for halting Zika, dengue and other emerging viral infections. The study appears online in the journal Cell Reports.

Cold viruses cause us irritation by penetrating into our cells and transporting their RNA into the cytoplasma of the infected cells. This is the only way they can multiply. The details of how the transfer of the RNA from within the virus occurs are difficult to study. However, a new method has been developed at TU Wien that can be used to analyse this process. It was developed from the combination of two established procedures - 'molecular beacons' and capillary electrophoresis in chip format. The new method has now been published and the article's title adorns the cover of the scientific journal Analytical and Bioanalytical Chemistry.

The system consists of two newly developed programs that automatically identify the 3-D positions of target areas based on the signals from the scintillators (shown as white dots), and determine...
"Clock genes" turn on and off, or "Express", in rhythmic patterns throughout the body to regulate physiological conditions and behaviour. When and how these genes express, especially in tissues outside the brain, is still poorly understood. Until now, scientists have lacked sufficient means to simultaneously monitor gene rhythms in specific tissues in freely moving subjects.

Lychnopholide, a substance isolated from a Brazilian plant, and formulated as part of "nanocapsules" cured more than half of a group of mice that had been infected experimentally with Chagas disease parasites. "Chagas disease affects millions of people, mainly in poor rural areas of 21 Latin American countries," said Marta de Lana, PhD. The research is published in online ahead of print June 20 in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology.

When we smoke cigarettes, dozens of genes important for immune defense are altered in the epithelial cells that line the respiratory tract. Several of these changes likely increase the risk of bacterial infections, viruses, and inflammation. Now, UNC School of Medicine scientists report that vaping electronic cigarettes alters those same genes and hundreds more that are important for immune defense in the upper airway.

The incidence of Parkinson's disease and parkinsonism increased significantly in 30 years from 1976 to 2005, Mayo Clinic researchers reported today in a study in JAMA Neurology. This trend was noted in particular for men age 70 and older. According to the researchers, this is the first study to suggest such an increasing trend.

A new procedure developed at Massachusetts General Hospital (MGH) may revolutionize the culturing of adult stem cells. In their report that has been published online prior to its appearance in the August 6 issue of Cell Stem Cell, the team describes generating and expanding airway stem cells from the sorts of tissue samples collected during routine treatment of lung disorders. The overall approach appears applicable to several other tissue types, including skin and the linings of the gastrointestinal and reproductive tracts.

DURHAM, N.C. -- Fungal infections can be devastating to human health, killing approximately 150 people every hour, resulting in over a million deaths every year, more than malaria and tuberculosis combined.
