Research shows plant-based polymers can disappear within seven months
Finding viable alternatives to traditional petroleum-based plastics and microplastics has never been more important. New research from scientists at UC San Diego and Algenesis shows that their plant-based polymers biodegrade — even at the microplastic level — in under seven months.

DARPA wants to bypass the thermal middleman in nuclear power systems
Nuclear power already has an energy density advantage over other sources of thermal electricity generation. But what if nuclear generation didn’t require a steam turbine? What if the radiation from a reactor was less a problem to be managed and more a source of energy? And what if an energy conversion technology could…
