Researchers at the University of Michigan have discovered that Restylane works by stretching fibroblasts, causing them to create new collagen. This natural collagen then contributes to reducing wrinkle appearance. The study also found that Restylane inhibits the breakdown of existing collagen.
Rebecca Slayton argues that while scientists can inform public debate, their role is limited due to the complexity of computing and testing. Computer professionals played a significant role in opposing missile defense proposals in the 1960s and 1980s, but their warnings were initially dismissed as pessimism.
A study by Thomas Foster at the University of Florida found that rats become forgetful due to an imbalance in brain cell communication. The researchers discovered that 'long-term depression' - a normal process that helps sculpt memory - can lead to rapid forgetting when it occurs excessively.
The American College of Physicians recommends periodic health evaluations to improve patient outcomes and reduce healthcare costs. A new study found that immunochemical FOBT is an effective tool for detecting colorectal cancer, with high sensitivity and specificity rates.
