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

Female chromosomes offer resilience to Alzheimer's

Women live longer than men with Alzheimer's because their sex chromosomes give them genetic protection from the ravages of the disease. Women get two 'doses' of a gene that only exists on the X chromosome. And some people, both male and female, have an especially potent variant of this gene. Long-term studies of older people, many of whom already had mild cognitive impairment, showed women with one or two copies of the variant progressed more slowly toward Alzheimer's.

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
