| Music-making and the flow of aerosols Posted: 14 Jul 2022 01:58 PM PDT If simply breathing can spread the SARS-CoV-2 virus to others nearby, what about blowing into a tuba? Researchers used fluid mechanics to study the movement of aerosols generated by professional musicians. |
| Bacteria in donor organs complicate immune response after transplantation Posted: 14 Jul 2022 11:51 AM PDT Organ transplant recipients take life-long immunosuppressive drugs to prevent their bodies from mounting an immune response against the donated organ, yet a substantial number of them still reject the organs.
