Nanodiamonds feel the heat

An international team of researchers created nanodiamond sensors that can act as both heat sources and thermometers, and is using them to measure the thermal conductivity inside living cells, which may lead to new diagnostics tools and cancer therapies

Wearable Electronics for Continuous Cardiac, Respiratory Monitoring

A small and inexpensive sensor, announced in Applied Physics Letters and based on an electrochemical system, could potentially be worn continuously by cardiac patients or others who require constant monitoring. A solution containing electrolyte substances is placed into a small circular cavity that is capped with a thin flexible diaphragm, allowing detection of subtle movements when placed on a patient’s chest. The authors suggest their sensor could be used for diagnosis of respiratory diseases.

Sounds, Smells Could Sway Our Self-Image

A lemony scent and light sounds could change the way you feel about yourself. Previously, researchers have shown that visual and tactile stimulation can change a person’s perception of their own body weight. Research being presented by Giada Brianza at the 179th ASA Meeting, has found our hearing and sense of smell can also change how we feel about our self-image, which could help improve healthy behaviors.

How Much Does the Way You Speak Reveal About You?

Listeners can extract a lot of information about a person from their acoustic speech signal. During the 179th ASA Meeting, Dec. 7-10, Tessa Bent, Emerson Wolff, and Jennifer Lentz will describe their study in which listeners were told to categorize 144 unique audio clips of monolingual English talkers into Midland, New York City, and Southern U.S. dialect regions, and Asian American, Black/African American, or white speakers.
