Multi-organ chip directly measures the biological impact of nanoparticles

What happens when we breathe in nanoparticles emitted by a laser printer, for example? Could these nanoparticles damage the respiratory tract or perhaps even other organs? To answer these questions, Fraunhofer researchers are developing the "NanoCube" exposure device.

How COVID-19 affects the female reproductive system

A new review in the Biology of Reproduction journal analyzed the relationship between the immune system and the female reproductive system while focusing on the effects of COVID-19-associated immune responses on the reproductive system. The study searched PubMed to identify peer-reviewed literature in English up to May 2022 and finally included 83 studies.
