Early warning signals could help monitor disease outbreaks

New research suggests early warning signals (EWSs) could help in the monitoring of disease outbreaks, such as COVID-19. The study found warnings could be detected weeks earlier than any rapid increase in cases. The findings could help governments and policy makers improve the accuracy of their decisions and allow timely interventions if needed. from Top Health News -- ScienceDaily https://ift.tt/3DvxDk4 via IFTTT

The mechanics of the immune system

Not only chemistry plays a role in the docking of antigens to the T-cell; micromechanical effects are important too. Submicrometer structures on the cell surface act like microscopic tension springs. Tiny forces that occur as a result are likely to be of great importance for the recognition of antigens. It has now become possible to observe these forces directly using highly developed microscopy methods.

Pathomechanisms in heart disease discovered

The largest protein in the human body, titin, enables elastic movements of our muscles, including the heart. Mutations in the titin gene (TTN) that impair this function and lead to heart muscle disease. The pathomechanisms behind this -- i.e. why TTN mutations trigger disease -- were unclear until now. A team of experts has now investigated these pathomechanisms in more detail and has gained ground-breaking insights. from Top Health News -- ScienceDaily https://ift.tt/3EOEi9S via IFTTT

Color-changing bandages sense and treat bacterial infections

Antibiotic resistance is one of the biggest threats to global health. Sensing and treating bacterial infections earlier could help improve patients' recovery, as well curb the spread of antibiotic-resistant microbes. Now, researchers have developed color-changing bandages that can sense drug-resistant and drug-sensitive bacteria in wounds and treat them accordingly. from Top Health News -- ScienceDaily https://ift.tt/37Gz2VU via IFTTT
