There are devices for measuring the stress-related hormone cortisol, but the devices’ short shelf life means that samples collected at home must be mailed to a lab for analysis. Researchers in China and the U.K. developed a stable cortisol detector, which hints at a possible future where sample collection and analysis can all be done at home.

There is ample evidence that nanoparticles can affect the healthy growth of a fetus, but the mechanisms involved are largely unknown. An interdisciplinary team led by Empa researchers showed that nanoparticles can cause indirect harm by disrupting the production of messenger substances in the placenta, leading to impaired blood vessel formation.

Though modern root canal treatments are not overly painful thanks to advancements in medical technology, the need to frequently clean the rotary file can lengthen procedure time. Researchers at Fraunhofer Institute for Ceramic Technologies and Systems IKTS created a file that features both rotational and vibrational motion, which reduces the amount of cleaning required.

Breath analyzers are handheld, rapid testing devices that could transform how the medical community diagnoses diseases and disorders. A new program housed under the U.S. Department of Defense aims to accelerate development of breath analyzers for rapid diagnosis of respiratory illnesses among warfighters. The program has so far provided funding to three different organizations, including ACerS Fellow Perena Gouma’s research group at The Ohio State University.
