But they are also opportunities for scientists to understand people's physiological processes while they are going about their everyday lives. |
| New tool enables mapping of protein interaction networks at scale Posted: 03 Aug 2021 09:13 AM PDT Bioengineers have developed a technology capable of revealing the protein-protein interactions (PPI) among thousands of proteins in a cell, in a single experiment. The tool, called PROPER-seq (protein-protein interaction sequencing), allows researchers to map the PPI network from their cells of interest within several weeks, without any specialized resources such as antibodies or pre-made gene libraries. |
| Experimental model of ovarian cancer shows effect of healthy cell arrangement in metastasis Posted: 03 Aug 2021 09:13 AM PDT A key element to slowing metastasis in ovarian cancer is understanding the mechanisms of how tumor cells invade tissues. Biophysics researchers explain how microscopic defects in how healthy cells line up can alter how easily ovarian cancer cells invade tissue. Using an experimental model, the group found that disruptions in the normal cellular layout, called topological defects, affect the rate of tumor cell invasion. |
| Does visual feedback of our tongues help in speech motor learning? Posted: 03 Aug 2021 09:13 AM PDT When we speak, we use our auditory and somatosensory systems to monitor the results of the movements of our tongue or lips. Since we cannot typically see our own faces and tongues while we speak, however, the potential role of visual feedback has remained less clear. Researchers explore how readily speakers will integrate visual information about their tongue movements during a speech motor learning task. |
| Artificial stomach reveals fluid dynamics of food digestion Posted: 03 Aug 2021 09:13 AM PDT Scientists have extensively studied how gastric juices in the stomach break down ingested food and other substances. However, less is known about how complex flow patterns and mechanical stresses in the stomach contribute to digestion. Researchers built a prototype of an artificial antrum to present a deeper understanding of how physical forces influence food digestion based on fluid dynamics. They reveal a classifying effect based on the breakup of liquid drops combined with transport phenomena. |
| Is reducing opioids for pain patients linked to higher rates of overdose and mental health crisis? Posted: 03 Aug 2021 09:13 AM PDT A new study found a 68% increase in overdose events and a doubling of mental health crises among patients who were on stable opioid therapy but had their doses tapered. |
