Life cycle assessments are used by corporations to determine the sustainability of raw source materials. Here, Chaplin-Kramer et al. develop an improved life cycle assessment approach incorporating spatial variation in land-use change, and apply this framework to a bioplastic case study.
A review of mineral exploration data and demand forecasts suggests that new international governance links are needed to ensure efficient and responsible future sourcing of minerals for sustainable development.
Synthetic nanoparticles containing rapamycin — a common immunosuppressant drug — when co-administered with any free antigen can induce immune tolerance, offering a way to rescue novel drugs that have failed in the clinic due to antidrug antibodies.
Energy storage is vital to the widespread rollout of renewable electricity technologies. Modelling shows that energy storage can add value to wind and solar technologies, but cost reduction remains necessary to reach widespread profitability.
Batteries are promising to support energy systems based on intermittent renewable energy, yet their investment attractiveness remains low. Using a techno-economic model, Stephan et al. find that returns can be increased and risks reduced if batteries are used for multiple stationary applications.
Disruption is often a bad word in established industries, and electricity generation is no exception. But with silicon solar cells getting ever closer to efficiency limits, innovative solutions are needed.
