Members of The Philadelphia Orchestra, including Carol Jantsch, principal tuba player, took part in a study led by Penn scientists Paulo Arratia and Douglas Jerolmack. Their investigation examined the aerosols professional musicians generate as they play. (Image: Courtesy of Paulo Arratia)

Music-making and the flow of aerosols

If simply breathing can spread the SARS-CoV-2 virus to others nearby, what about blowing into a tuba? Researchers from the School of Engineering the School of Arts & Sciences used fluid mechanics to study the movement of aerosols generated by musicians.

Shapeshifting microrobots can brush and floss teeth
Graphic shows how nanoparticle-based microrobots can remove dental plaque from teeth with their motion and the activity of hydrogen peroxide (H2O2) to kill microbes

Shapeshifting microrobots can brush and floss teeth

In a proof-of-concept study, researchers from the School of Dental Medicine and School of Engineering and Applied Science shows that a hands-free system could effectively automate the treatment and removal of tooth-decay-causing bacteria and dental plaque.

Center for Engineering Mechanobiology 2.0: Developing ‘mechanointelligence’
Microscopic view of an individual cell illuminated in bright colors.

The dynamics governing mechanointelligence vary greatly along time- and length-scales, so detailed models of individual cells and their components are necessary to connect the effects of their physical environments to the downstream effects those forces have on biological processes.
