It’s possible to build stronger systems to deliver oxygen: here’s what it takes

An effective oxygen system requires prompt recognition of who needs oxygen, a reliable oxygen supply and safe delivery to those who need it.
Maker spaces give engineers and designers the tools to build low-cost medical equipment using locally available materials. Brandon Martin, Rice University

‘Frugal design’ brings medical innovations to communities that lack resources during the pandemic

Engineering students in Malawi and Tanzania have used the materials and tools available to them to build ventilators, personal protective equipment and UV disinfection systems.

Lab studies suggest medicinal plants can help repair human bone and tissue

Tissue engineering and regenerative medicine is based on three key requirements working together: signals from body tissues and organs, responding stem cells, and scaffolds.
Biomedical innovations can work with traditional methods like x-rays to guide doctors’ decisions. Reuters/Adriane Ohanesian

Africa needs to start creating its own medical technology. Here’s how

African countries need to start producing and developing their own medical devices. Suitably skilled biomedical engineers are needed for this sort of innovation to take root.
Biomedical engineering involves the application of engineering solutions to medical problems. Employment in the field is projected to grow 23 per cent from 2014 to 2024. (Shutterstock)

A war made me realize: The world needs biomedical engineers

One professor explains how war in Iran led her to a career in biomedical engineering - a rapidly growing field that offers students exciting opportunities to serve humanity.
