Controlled diabetics have new reason to smile

A recent study found that poorly controlled type 2 diabetic patients are more likely to develop severe periodontal disease, with elevated serum triglycerides contributing to the issue. Reducing cholesterol and serum triglyceride levels through diet and exercise may help improve quality of life and oral health in diabetics.

Plaque, the hallmark of Alzheimer's disease is revealed in three dimensions

For the first time, researchers have produced three-dimensional images of Alzheimer's disease plaques. The milestone was made possible by combining high-resolution magnetic resonance microscopy with powerful computers. The technique allows for non-invasive detection and study of plaque development in human and animal brain tissue.

Lizard research bolsters theory that forest edges are hotbeds of speciation

A recent study published in the Proceedings of the National Academy of Science found significant differences in physical appearance and reproductive maturity among skinks living at forest edges compared to those in isolated populations. The research suggests that natural selection, rather than geographic isolation, plays a key role in ...
