Researchers provide an update on how electrical impulses in the heart travel from cell to cell. The connections between cells forming the low resistance pathway and facilitating the current flow are called gap junctions. Each consists of many channels, which are formed when specific proteins from one cell dock and fuse to the proteins from another cell. The scientists delve into the properties of gap junctions and their constituent proteins. from Top Health News -- ScienceDaily https://ift.tt/3yZnUAJ via IFTTT

Children exposed to elevated levels of air pollution may be more likely to have poor inhibitory control during late childhood and poor academic skills in early adolescence, including spelling, reading comprehension, and math skills. Difficulty with inhibition in late childhood was found to be a precursor to later air pollution-related academic problems. Interventions that target inhibitory control might improve outcomes. from Top Health News -- ScienceDaily https://ift.tt/2UbimnI via IFTTT

A recently published study identifies 11 rare candidate variants for Alzheimer's disease. Researchers found 19 different families in Utah that suffered from Alzheimer's disease more frequently than what is considered normal. from Top Health News -- ScienceDaily https://ift.tt/2UNacBV via IFTTT

In addition to chemical factors, mechanical influences play an important role in the natural growth of human organs such as kidneys, lungs and mammary glands - but also in the development of tumors. Now a research team has investigated the process in detail using organoids, three-dimensional model systems of such organs which are produced in the laboratory. from Top Health News -- ScienceDaily https://ift.tt/3r65gV5 via IFTTT

New research shows how control over self-propelled microswimmers could be achieved using exotic materials named 'nematic liquid crystals' - whose viscosity and elasticity can vary depending on the direction of an applied force. from Top Health News -- ScienceDaily https://ift.tt/2U08Fc0 via IFTTT

As the complexity of radiation therapy has grown, so too has the amount of data that goes into treatment machines. With more data comes more opportunity for errors in data transfer. A medical physics researcher is working to make those errors less likely. from Top Health News -- ScienceDaily https://ift.tt/3yXtvqX via IFTTT

A new study shows that a diet rich in isoflavone, a phytoestrogen or plant-based compound that resembles estrogen, protects against multiple sclerosis-like symptoms in a mouse model of the disease. Importantly, the isoflavone diet was only protective when the mice had gut microbes capable of breaking down the isoflavones. from Top Health News -- ScienceDaily https://ift.tt/3i5a7l5 via IFTTT
