ISAE-SUPAERO Achieves a Scientific First in the Exploration of Mars
NASA's Perseverance rover has been surveying Mars' Jezero crater for more than a year. He recorded for the first time the "sound environment" of the red planet thanks to the Martian microphone developed by ISAE-SUPAERO, on board the US-French instrument SuperCam. An international team publishes in Nature on April 1, 2022 the scientific analysis of these sounds.
The ISAE-SUPAERO "Space Systems in Planetology & Applications" research team has been convinced for years of the scientific interest of developing a microphone to better understand Mars. On the heritage of large-scale space missions with the Jet Propulsion laboratory Caltech such as InSight, or its contributions to Earth Science missions like the French agency CNES Stratéole-2 stratospheric balloons, the Institute has in fact been working for more than 10 years on modeling tools to study the interaction of planetary atmospheres with rocky planets.
In addition to the design and testing of the SuperCam microphone, ISAE-SUPAERO scientists have played a pioneering role in atmospheric analyzes of the red planet and the results are very promising:
“For example, we have, for the first time, high-frequency measurements of the turbulence of the Martian atmosphere, a key parameter in Martian climatology models. More broadly, the data collected will allow us to do comparative planetology, that is to say, to develop models applicable to the planet Mars, to ultimately better understand its differences with the Earth,” says David Mimoun. , who leads the microphone science team at ISAE-SUPAERO.
For the next step, ISAE-SUPAERO, in collaboration with NASA's Jet Propulsion Laboratory and CNES, is already working on the next solar system exploration missions. The next destination will likely be the planet Venus, which is similar to Earth in size, although its temperature of 400 degrees and surface pressure of 90 atmospheres make it technically very difficult to explore.
Analysis of the climate patterns of Earth-like planets is essential to understanding the global warming we are experiencing. This mission to Venus, expected within 10 years, will include stratospheric balloons that will allow scientists to explore the internal structure of this planet, thanks in particular to knowledge relating to the propagation of sound in carbon dioxide acquired during the Mars 2020 mission.

Anterra Capital: Pandemic and Food Price Inflation Fuel Investor Interest to Accelerate Transformation of the Food and Ag Sector18.5.2022 07:00:00 CEST | Press release
A crushing pandemic and, more recently, the Ukraine war have convinced investors more than ever that the world needs to radically change how it produces, distributes and consumes food, says Adam Anders, managing partner of the international food and agriculture specialist venture capital firm Anterra Capital (“Anterra”). Anders: “The pandemic highlighted the fragility and adverse health impacts of our current food system: soaring prices, empty shelves in stores; the fact that unhealthy diets are a major risk factor for getting Covid; that the way we treat farm animals could trigger the next pandemic. Post our final closing, the devastating impact of the Ukraine War on the global food supply has increased the awareness among investors even further. This, plus our focus on deploying proven biotech and digital solutions to shake up the lagging Food and Ag-sector, go a long way in explaining the higher than expected interest in our second fund.” Anterra is proud to announce the closing of

Emendo Biotherapeutics’ next generation CRISPR gene editing technologies achieve breakthrough results with allele-specific approach for ELANE -related Severe Congenital Neutropenia as presented at ASGCT Annual Meeting17.5.2022 22:15:00 CEST | Press release
Emendo Biotherapeutics presented the results of its next generation CRISPR-based gene editing approaches for several indications in an oral presentation and three posters at the 25th Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT) held May 16-19, 2022, in Washington, D.C. Emendo presented pre-clinical data for the treatment of ELANE-related Severe Congenital Neutropenia using an allele-specific editing approach, demonstrating the power of Emendo’s dual technology platforms that enable the development of a highly specific editing composition that demonstrates no off-targets and complete allele specificity. Significantly, the lack of off-target achieved by Emendo’s engineered and optimized OMNI nuclease also eliminated any translocations. Edited patient derived CD34+ cells differentiated normally into neutrophils both in-vitro and in-vivo, showing full engraftment and reconstitution of all blood lineages, as required for the desired therapeutic effect. “ELANE-based
