Structural basis for bacterial energy extraction from atmospheric hydrogen
Abstract
Diverse aerobic bacteria use atmospheric H2 as an energy source for growth and survival1. This globally significant process regulates the composition of the atmosphere, enhances soil biodiversity and drives primary production in extreme environments2,3. Atmospheric H2 oxidation is attributed to uncharacterized members of the [NiFe] hydrogenase superfamily4,5. However, it remains unresolved how these enzymes overcome the extraordinary catalytic challenge of oxidizing picomolar levels of H2 amid ambient levels of the catalytic poison O2 and how the derived electrons are transferred to the respiratory chain1. Here we determined the cryo-electron microscopy structure of the Mycobacterium smegmatis hydrogenase Huc and investigated its mechanism. Huc is a highly efficient oxygen-insensitive enzyme that couples oxidation of atmospheric H2 to the hydrogenation of the respiratory electron carrier menaquinone. Huc uses narrow hydrophobic gas channels to selectively bind atmospheric H2 at the expense of O2, and 3 [3Fe–4S] clusters modulate the properties of the enzyme so that atmospheric H2 oxidation is energetically feasible. The Huc catalytic subunits form an octameric 833 kDa complex around a membrane-associated stalk, which transports and reduces menaquinone 94 Å from the membrane. These findings provide a mechanistic basis for the biogeochemically and ecologically important process of atmospheric H2 oxidation, uncover a mode of energy coupling dependent on long-range quinone transport, and pave the way for the development of catalysts that oxidize H2 in ambient air.

LA REVOLUTION ECOLO-ENERGETIQUE EST EN MARCHE.
Le risque principal est la monétisation de l'air. On a déjà prévenu depuis longtemps.
En tout cas, ça justifie l'arrêt du nucléaire puisqu'une technologie lui est supérieure en terme d'indépendance de production locale. Reste le problème des brevets, qui évidemment va nous le mettre de toutes façon bien profond.
la conversion de l'hydrogene par l bactérie est une réction-doxydo-réduction donc d'un échange d'életrons donc de profustion d'élicricité

Climate change has increased the need for new technologies that produce electric energy. Hydrogen is considered the ideal chemical for energy storage. In the storage process, electrolyzers and fuel cells store peak power production and use off-peak production to deliver electricity from wind and solar power to the grid. With the COMSOL Multiphysics® software, you can set up physics-based, high-fidelity models of fuel cells and electrolyzers, and account for material transport, charge transport, heat transfer, multiphase flow, and electrochemical reactions in your simulations.
Join us for COMSOL Day: Hydrogen Technologies to learn from keynote talks, technical presentations, and a panel discussion about the benefits of using multiphysics modeling to study and design fuel cells, electrolyzers, and reactors. We will also give an overview of the relevant features in COMSOL Multiphysics® and demonstrate how the software can be used across large development teams.

Un cours d'économie ! C'est ce que nous propose cet article publié sur le média ami La Ultima Hora. Il démontre la modernité de la pensée keynésienne (de John Keynes, économiste, dont se sont inspirés tous les dirigeants qui ont voulu un État stratège, capable de planifier l'économie réelle, et d'organiser l'intervention publique pour le bien de tous.
Ce texte a été publié le 3 juin 2020 sous le titre "keynesianismo o barbarie" par le pôle "économie" de la Ultima Hora. Accessible en espagnol.
La economía es una ciencia, dicen que lúgubre, aunque con deslumbrantes destellos. Uno de ellos fue el keynesianismo, una corriente que surge del pensamiento de John Maynard Keynes. Este autor fue poco a poco forjando una nueva forma de pensar en economía hasta llegar a lo que hoy conocemos como macroeconomía.

Modernidad de Keynes / Modernité de Keynes
...
Hoy en día se mantiene por supuesto los aportes de Keynes a la ciencia económica: todos los países utilizan sistemas de cuentas nacionales para medir agregados, gestionan macroeconómicamente el ciclo, tienen estabilizadores automáticos, utilizan la política fiscal. Pero se mantiene también la retórica neoclásica: el sector público distorsiona, daña y hay que reducirlo hasta su mínima expresión. Hoy más que nunca hace falta reivindicar la modernidad que supuso Keynes frente al liquidacionismo de las tendencias más reaccionarias. Lo que supone que el neoclasicismo domine la ciencia económica y domine los discursos públicos. Los conservadores siempre han estado en contra de cualquier conquista de las clases populares. Por eso tenemos que reivindicar aquello que nos permite expandir nuestra capacidad social.

Finally, what would be the use of all of these intelligences if we do not do something with them? We need the capacity to put it all together in order to generate new ideas and concepts. The four intelligences - academic, emotional, artistic, ecological - can be combined so as to create a fifth intelligence: the capacity to implement change.

Finalement, quel pourrait être usage de toutes ces intelligences si nous n'en faisions rien ?

The purpose of this review was to look back over the past decade of country reports published in Global Information Society Watch (GISWatch) and attempt to identify trends in civil society perspectives on what needed to be done to create a people-centred information society. The period for analysis was, more accurately, just over a decade: 2007-2017, during which a GISWatch report was produced each year – a total of 11 reports. Over this period, 510 country reports covering 97 countries were published, a substantial record of civil society activism on information and communications technology (ICT) and internet rights. Over 1,900 advocacy recommendations – what were called “action steps” – were proposed by authors.
...
This review is a starting point for action – and we hope that activists can use it as a tool for build- ing future strategies. It can be read in conjunction with a similar review on the issue of internet rights and democratisation conducted in 2011 by APC. While it can shed light on gaps in advocacy approaches when addressing new advocacy frontiers, it also suggests that there are advocacy needs from the past that may require renewed attention.
This work was carried out with the aid of a grant from the International Development Research Centre, Ottawa, Canada. The views expressed herein do not necessarily represent those of IDRC or its Board of Governors.

How to use Prometheus, PostgreSQL + TimescaleDB, and Grafana for storing, analyzing, and visualizing metrics
...
Prometheus is quite simple to start with. What makes Prometheus awesome is its unapologetic approach to solving monitoring in a simple and straightforward way. Its philosophy is to do one thing, and do it well. You can see this approach reflected in the PromQL language which is known for being powerful, yet simplistic.
