Randomized controlled trials, or RCTs, are believed to be the best way to study the safety and efficacy of new treatments in clinical research. However, a recent study found that people of color and white women are significantly underrepresented in RCTs due to systematic biases.

In a concert, members of the audience can respond emotionally to music, owing to their biological synchronization to the audio input. However, the mechanism underlying this biological response is unclear. Now, a pioneering study has found that music-induced heart-rate synchronization is highly correlated within an individual, compared to between two randomly selected individuals. It has been determined that individual differences in cognition reduce the consistency in physiological responses and affect synchronization.

A colder nose and warmer cheeks may be a telltale sign of rising blood pressure. Researchers discovered that temperatures in different face regions are associated with various chronic illnesses, such as diabetes and high blood pressure. These temperature differences are not easily perceptible by one's own touch but can instead be identified using specific AI-derived spatial temperature patterns that require a thermal camera and a data-trained model. With further research, doctors could one day use this simple and non-invasive approach for early detection of diseases.

Researchers developed a prototype of an implantable microphone for a cochlear implant. Their device, which senses the movement of the ear drum in the inner ear, performed as well as commercial hearing aids and could someday enable a fully internalized cochlear implant.
