Je reporte
Excusez-moi mais…
Bon j’ai pas trouver sur le net et en même je sais pas chercher ça m’énerve vous pouvez pas savoir
Mais c’est pas la question
Comme certains le savent je suis passionnée par tous les trucs du style permaculture mais surtout l’aquaponie
Et je me posais cette question après un reportage à la télé
Les plantes ont besoin de lumière et on est capable aujourd’hui de contrôler cette lumière
Bleu en pleine nuit jaune en journée ou rouge en soirée
Je trouve ça très intéressant
Mais dans le cadre d’aquaponie si la lumière est importante pour les plantes elle est gênante pour l’eau et les poissons tous les aquariophiles le savent
Je me demandais si on ne pouvait pas par exemple installer des lumières au dessus des bassins des poissons mais d’une couleur spécifique qui serait favorable aux poissons sans pour autant laisser se développer des algues qui peuvent s’averer toxique dans certains cas
Voilà ce que je cherche sur le net
Si quelqu’un a des infos ou un axe de réflexion je prend et je le remercie
L’autre truc que je recherche parce que ça m’interresse ce sont les BIOPILES
Ou en est on ?
J’ai regardé mais je tombe toujours sur les mêmes articles
Par exemple je sais qu’en Inde il devait y avoir des travaux intéressant mais rien de neuf depuis 3/4 ans
On cherche plus ?
Perso je sais que le meilleur truc c’est de passer par la bactérie Escherichia coli mais bon quand on sait ce qu’il faut faire pour la récupérer … non merci beurk
Je cherche donc une solution

Visualizing protein synthesis in human mitochondria at super-resolution.High-resolution imaging reveals compartmentalization of mitochondrial protein synthesis in cultured human cells
In mitochondria from various species, the OXPHOS complexes reside mainly in the invaginated cristae membranes, as opposed to the inner boundary membrane (IBM) that parallels the mitochondrial outer membrane. However, the IBM contains dynamic contact sites enriched for translocases that import proteins from the cytosol. As the majority of OXPHOS components are imported and need to be integrated in assembly with the mtDNA-encoded components, where does intramitochondrial translation occur? Here we report: 1) a method for visualizing protein synthesis in human mitochondria at super resolution; 2) that synthesis is enriched at cristae membranes, in preference to the IBM; and 3) that sites of translation are spatially separated from RNA granules where RNA processing, maturation, and mitoribosomal assembly occur. All study data are included in the article and/or supporting information.www.pnas.org

Proteins and their behaviors at nanometer scales.
Looking at the kinesin motors: Wow!

Kinesin motor transports vesicle along microtubule.Germanium nanospheres for ultraresolution picotensiometry of kinesin motors
Simultaneously measuring the nanoscale motion and forces that molecular machines generate provides insights into how they work mechanically to fulfill their cellular function. To study these machines, Sudhakar et al. developed germanium semiconductor nanospheres as probes for so-called optical tweezers. With these high–refractive index nanospheres, they improved the resolution of optical tweezers and discovered that the motor kinesin takes 4-nanometer substeps. Further, instead of detaching from their microtubule track under load, motors slid back on it, enabling rapid reengagement in transport. The new technology will allow investigation of a range of other proteins and their behaviors at nanometer scales. Science , this issue p. [eabd9944][1]### INTRODUCTION Cytoskeletal motors drive many essential mechanical processes inside cells. For example, kinesin motors are key for cell division or vesicle transport. Kinesin-1 transports cargo along microtubules by coupling adenosine 5′-triphosphate (ATP) hydrolysis to perform mechanical work against piconewton loads. This force generation and overall transport distance are limited by motor detachment. However, how kinesins walk and detach is still unclear. To simultaneously measure the nanoscale motion and forces of molecular machines, optical tweezers are often used. In the tight, mostly infrared laser focus of optical tweezers, small dielectric particles can be trapped and used as handles for sensitive position and force measurements. Because optical forces scale with the particle volume, piconewton force measurements with nanoparticles require a high laser power. This high power leads to excessive heating and precludes biological measurements. Therefore, for biological single-molecule measurements, micrometer-sized probes are used. However, such probes have a large hydrodynamic drag and therefore lack the spatiotemporal resolution to unravel important fast or small details in the mechanochemistry of molecular machines. These details remain hidden in the storm of Brownian motion. ### RATIONALE To overcome this practical resolution limit of optical tweezers and resolve so-far hidden conformational changes of proteins, we sought to compensate the volume scaling of optical trapping forces by the use of probe materials with a very high refractive index and low light absorption. This compensation should allow the use of nanometer-sized probes and the generation of piconewton optical forces without detrimental heating but with improved temporal response and spatial precision. Promising materials include silicon and germanium that become transparent in the near-infrared, with very high refractive indices exceeding 4. However, efficient methods to fabricate such semiconductor nanospheres suitable for optical trapping do not exist. ### RESULTS We developed a solution-based method to synthesize germanium nanospheres. With a diameter of roughly 70 nm, they are about an order of magnitude smaller as compared with commonly used microspheres and still allowed piconewton force measurements. To find out how kinesin works mechanically, we developed an in vitro reconstituted assay. To this end, we coated the nanospheres with a lipid bilayer [the white rim in the transmission electron microscopy (TEM) image] to mimic vesicles and to be roughly their size inside cells. When we bound kinesin-1 to these “vesicles” and measured the interaction of single motors with microtubules under piconewton tension, we discovered that each hydrolysis cycle is broken up into two 4-nm center-of-mass substeps. The durations of these substeps alternated in their force and ATP dependence, with the duration of one of the substeps being nearly independent of both parameters. Furthermore, when subjected to hindering loads, motors never detached from the microtubule. Instead, motors slipped along the microtubule in 8-nm steps on microsecond time scales. These slip steps are consistent with a bond-rupture model that involves protein friction between the motor and its track. Unexpectedly, motors usually did not detach after a slip event but reengaged in motility that rescued cargo transport. ### CONCLUSION Germanium nanospheres are promising for bioimaging, sensing, optoelectronics, nanophotonics, and energy storage. For optical trapping, the nanospheres open a new temporal window by which to uncover hidden dynamics in molecular machines. The direct observation of load-bearing kinesin substeps resolves a long-standing controversy. Slipping and rescues should allow load distribution and synchronization when motors operate in teams. Understanding their mechanochemistry is important for a better understanding of cellular transport and other essential molecular functions of kinesins, with implications, for example, for neurodegenerative diseases and cancer. ![Figure][2]</img> Ultraresolution kinesin traces with optically trapped germanium nanospheres. Kinesins are molecular machines that transport vesicles along microtubules inside cells. Membrane-coated germanium nanospheres (TEM micrograph, left) improved the spatiotemporal resolution of optical tweezers and allowed the measurement of substeps during the normal kinesin stepping cycle. Under load, kinesins did not detach but slipped along the microtubule, which led to the discovery of rescues for vesicle transport. Kinesin motors are essential for the transport of cellular cargo along microtubules. How the motors step, detach, and cooperate with each other is still unclear. To dissect the molecular motion of kinesin-1, we developed germanium nanospheres as ultraresolution optical trapping probes. We found that single motors took 4-nanometer center-of-mass steps. Furthermore, kinesin-1 never detached from microtubules under hindering load conditions. Instead, it slipped on microtubules in microsecond-long, 8-nanometer steps and remained in this slip state before detaching or reengaging in directed motion. Unexpectedly, reengagement and thus rescue of directed motion was more frequent. Our observations broaden our knowledge on the mechanochemical cycle and slip state of kinesin. This state and rescue need to be accounted for to understand long-range transport by teams of motors. [1]: /lookup/doi/10.1126/science.abd9944 [2]: pending:yesscience.sciencemag.org

All n all. I spent around 5 days chasing this bug through my code. I generated Gigabytes of log files and had to get down to the precision of 7.5 grains of sand on the planet Earth. The compiler missing a key function call turned out to be the cause of the issue. Many times, while trying to find the root cause I found myself questioning my ability to write code, diagnose bugs and remain sane. I’m glad I found an answer and have a way forward.#programming #science compiler
