Lithium-ion batteries need to be greener and more ethical

July 7, 2021
Nature EDITORIAL 29 June 2021 Nature 595, 7 (2021) doi: https://doi.org/10.1038/d41586-021-01735-z A low-carbon future rests on an essential, yet also problematic, technology. Lithium-ion rechargeable batteries — already widely used in laptops and smartphones — will be the beating heart of electric vehicles and much else. They are also needed to help power the world’s electric grids, because...

Biological and health-related effects of weak static magnetic fields (≤ 1 mT) in humans and vertebrates: A systematic review

August 28, 2020
Published: June 9, 2020https://doi.org/10.1371/journal.pone.0230038 Abstract Background There is a rapid development in technologies that generate weak static magnetic fields (SMF) including high-voltage direct current (HVDC) lines, systems operating with batteries, such as electric cars, and devices using permanent magnets. However, few reviews on the effects of such fields on biological systems have been prepared and...
