A novel bioactive glass incorporated in a toothpaste significantly reduced tooth sensitivity through prompt and lasting symptom relief, results from an ADA Forsyth Institute-administered clinical trial showed.

The first-in-human trial established the safety and efficacy of Sensi-IP, a bioactive glass technology developed by IR Scientific. ADA Forsyth researchers found statistically significant reductions in tooth sensitivity scores in the test group compared to a control group using a common sodium fluoride (NaF) toothpaste.

Cadmium telluride photovoltaics, a solar energy generation technology once considered limited in its potential, is poised for significant growth in the United States, according to a team of scientists analyzed challenges and proposed corresponding research goals in new research published in the peer-reviewed journal Joule.

Concrete contains a diversity of materials that scatter sound waves and make clear imaging difficult to obtain. In Applied Physics Letters, researchers created a high-resolution 3D ultrasonic imaging system for concrete that automatically adapts to different types of structures, sending frequencies into the material and using a vibrometer to capture the outcoming waves. The system can handle a wide range of frequencies, which means that even if ultrasonic waves are scattered by materials in the concrete, those that do make it through are still detected.
