With power generation in the grid becoming more diverse and decentralized, energy storage is becoming more and more important. Eduard Heindl‘s gravity storage is an approach to storing electrical energy as potential energy by lifting huge masses cut out of the ground. While this sounds crazy, there are lots of reasons why this makes sense. In the episode we discuss then need, the general approach, the construction process and some of the engineering challenges. We also look at the innovation process, the path from the idea to something that is ready to be built.
On October 20, the BepiColombo started its flight to Mercury on an Ariane 5 from Kourou. I was at the launch press event at ESOC in Darmstadt to follow the launch and to record a couple of interviews. The episode consists of three major parts. The first part is an interview with Pablo Munoz about mission analysis and flight dynamics. The second part looks at the science with Joe Zender, Roberto Peron, Ajako Matsuoka and Joana Oliveira. And part three are multiple short takes with Paolo Ferri, Andreas Rudolph and Fabian Luedicke recorded in the middle of the night at ESOC.
CRISPR is a family of DNA sequences in bacteria and archaea that are a part of these organisms’ cellular defense system. A recent discovery showed how this mechanism can be used to edit genes much more easily than legacy methods. In this episode I chat with Sam Sternberg about the naturally occuring CRISPR systems, how they work, and how CRISPR together with its associated enzymes can be used to cut, and subsequently, edit, DNA. We conclude the episode with an outlook on the potential use in medicine.
