In a new study, an international team of plant researchers including the Institute of Botany at TU Dresden has discovered an unusual and previously unknown reproductive strategy in plants: the Greek pipevine species Aristolochia microstoma produces a unique mixture of volatiles that resembles the smell of dead and decaying insects to attract the pollinating fly genus Megaselia (also known as coffin flies ) to its trap-flowers. The study was recently published in the open-access journal Frontiers . ....
A new technique uses high-throughput sequencing, instead of a microscope, to obtain ultra-high-resolution images of gene expression from a tissue slide. ....
This study will benefit scientists and experts in brain research where new discoveries of biomarkers are needed to form part of routine clinical practice protocols. The study relies on zebrafish Parkinson s Disease model, showing how cytosolic dsDNA of mitochondrial origin can accumulate in brains cells thereby contributing to PD pathogenesis. The evidence presented in this manuscript illustrates that upregulation of DNAse II can counteract the dsDNA deposits, thereby blocking the IFI16-mediated cascade of proinflammatory responses. ....
Bacteriophages are still a relatively unknown component of the human microbiome. However, they can play a powerful role in the life cycles of bacteria. Biochemist Thomas Böttcher from the University of Vienna and Ph.D. student Magdalena Jancheva were able to show for the first time how Pseudomonas bacteria use a self-produced signal molecule to selectively manipulate phages in a competing bacterial strain to defeat their enemy. ....

Blood samples for both groups were taken at baseline and after 26 weeks. view more Credit: Florida Atlantic University Increasing evidence shows that physical activity and exercise training may delay or prevent the onset of Alzheimer s disease (AD). In aging humans, aerobic exercise training increases gray and white matter volume, enhances blood flow, and improves memory function. The ability to measure the effects of exercise on systemic biomarkers associated with risk for AD and relating them to key metabolomic alterations may further prevention, monitoring, and treatment efforts. However, systemic biomarkers that can measure exercise effects on brain function and that link to relevant metabolic responses are lacking. ....
