Only 16% of all counties in the U.S. offered pregnant people the opportunity to attempt labor after a previous cesarean section between 2016 and 2021, according to University of Massachusetts Amherst research that provides the most recent national look at this trend.

Concordia researchers have developed a new method of monitoring and tracking how disease-causing particles, or pathogens, spread from one place to another. The tool uses real-time camera- and sensor-based tracking of infected individuals, as well as algorithm-based air and pathogen dispersal models, to assess infection risk levels. It can also alert ventilation systems to optimize air flow and reduce lower the risk of infecting others.

Within the next few years, doctors may be able to spot signs of Alzheimer’s disease and other dementias using routine eye exams well before symptoms appear, a new study suggests. The research, recently published in Alzheimer’s & Dementia, links abnormal changes in the tiny blood vessels of the retinas of mice with a common genetic mutation known to increase Alzheimer’s disease risk.
