Unprecedented audio recordings taken by NASA’s Perseverance rover are transporting us to the surface of the Red Planet, allowing us to hear the sound of a gentle alien breeze, and the click-clicking of lasers zapping a Martian rock.

We’re exactly three weeks into the Perseverance mission, so it’s still early days. The project is in the deployment phase, with the Mars 2020 team systematically deploying each of the rover’s many instruments to make sure they’re working properly and configured for the science phase of the mission. Perseverance will spend the next two years or more exploring Jezero crater, so there’s no need to rush things along.

New biosensor measures extracellular hydrogen peroxide levels with nanometer-resolution
Several processes in the human body are regulated by biochemical reactions involving hydrogen peroxide (H
2O
2).
2O
2 is generally toxic because of its oxidant character. The latter means that it converts (oxidizes) biochemical molecules like proteins and DNA.
The oxidizing property of H
2O
2 is of potential therapeutic relevance for cancer, though: deliberately causing tumor cells to increase their H
2O
2 concentration would be a way to destroy them. In light of this, but also for monitoring pathologies associated with H
2O
2 overproduction, it is crucial to have a means to reliably quantify hydrogen peroxide concentrations in the extracellular environment.

Molecular and cellular bioanalyses are increasingly moving towards faster and more sensitive approaches. Key techniques such as Raman spectroscopy, fluorescence spectroscopy, dynamic light scattering, nanoparticle tracking analysis and surface plasmon resonance imaging now allow for easy characterization of all kinds of analytes, from cells to small molecules.
In this webinar, Nathalie Vollmer, Christelle Mégier and Thibault Brulé, from HORIBA Scientific, discuss these different techniques and their application in life sciences and pharmaceutical research. The potential of these techniques is also illustrated through different application examples for bacteria
