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

Nicotine may harm human embryos at the single-cell level

Nicotine induces widespread adverse effects on human embryonic development at the level of individual cells, researchers report. Single-cell RNA sequencing of human embryonic stem cell (hESC)-derived embryoid bodies revealed that three weeks of nicotine exposure disrupts cell-to-cell communication, decreases cell survival, and alters the expression of genes that regulate critical functions such as heart muscle-cell contractions.

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
