Acollaborative team developed an alginate-based hydrogel system that mimics the viscoelasticity of the natural extracellular matrix in bone marrow. By tweaking the balance between elastic and viscous properties in these artificial ECMs, they could recapitulate the viscoelasticity of healthy and scarred fibrotic bone marrow, and study the effects on human monocytes placed into these artificial ECMs. (Image: Adam Graham/Harvard CNS/Wyss Institute at Harvard University)

Deconstructing the mechanics of bone marrow disease

A new understanding of how mechanical features of bone marrow affect resident immune cells in a fibrotic cancer points to future therapeutic strategies for cancers and fibrotic diseases.

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.
