Carbon-fiber-plated shoes have helped runners to set new world records, but little has been published about the potential injuries that can be sustained from using this technology. Researchers in the United States and Germany published an open-access paper to raise awareness of possible health concerns around the use of carbon-fiber-plated footwear.

Video: Translating bioceramic research from the lab to the clinic—a discussion with William Bonfield
To fulfill the growing demand for bioceramics and bioactive glasses, scientists will need to not only innovate new materials but translate them to market. In an interview, William Bonfield, recipient of the 2021 Larry L. Hench Lifetime Achievement Award, shares advice for others looking to translate their innovations into clinical settings.

Methods that conserve or semi-conserve a dental restoration during removal often risk harming the underlying tooth. Researchers in the U.S. and Poland reviewed the current literature on erbium laser-assisted ceramic debonding to identify the parameters needed for safe application of this method.

Determining when to seek help for mental stress can be difficult. However, the recent identification of discernible odor substances that emanate from the skin during emotional tension may offer a way to quantifiably measure mental stress. Two researchers in Japan propose nanosheet-type tin oxides could be used as gas sensors to detect these substances.

Removal of zirconia dental restorations is challenging and time consuming due to their high strength. Manufacturers offer diamond rotary instruments marketed specifically for removing zirconia restorations, but a new study reaffirmed that these instruments do not perform better or generate less heat than conventional ones.

Most rotator cuff repair procedures focus on the tendon, but the real problem is that the muscle degenerates and accumulates fat. University of Connecticut School of Medicine researchers led by ACerS Fellow Cato Laurencin developed a graphene-polymer matrix that induces a reversal of muscle degeneration, thereby greatly lowering the risk of rotator cuff retear injuries.
