Italy's Phlegraean Fields is a hotspot of volcanic activity—an ever-shifting landscape pocketed with acidic hot springs. This huge caldera is a part of the Campanian volcanic arc, which includes Mount Vesuvius, whose eruption wiped out the Roman city of Pompeii in 79 C.E. Yet, despite the hostile and scalding conditions of this environment, some microorganisms thrive.
One of the hardest-working organisms in the ocean is the tiny, emerald-tinged Prochlorococcus marinus. These single-celled "picoplankton," which are smaller than a human red blood cell, can be found in staggering numbers throughout the ocean's surface waters, making Prochlorococcus the most abundant photosynthesizing organism on the planet. (Collectively, Prochlorococcus fix as much carbon as all the crops on land.) Scientists continue to find new ways that the little green microbe is involved in the ocean's cycling and storage of carbon.
Plastids are important organelles that can be engineered to enhance photosynthetic and metabolic traits in plants. This study identifies a chloroplast-targeting peptide that is highly efficient in delivering biologically functional proteins to plastids in plants.
#IndianGhostPipe - #MonotropaUniflora
Herbaceous, #perennial flowering plant.
It can't generate its own chlorophyll & is #parasitic - specifically #mycoheterotroph. Its #symbiotic #fungi hosts are in the #Russulaceae family.
Through the fungal web of #mycorrhizae, #GhostPipe roots sap food from where the host fungi are connected to the #photosynthetic #trees. Clustered node roots of this plant are covered in hairs called #cystidium. The #cystidia found on these roots allow easy attachment to #FungiHyphae. As it's not dependent on sunlight to grow, it can grow in very dark environments, like understories of forests.
#Indigenous #Cherokee peoples feature the "pipe plant" in some of their #CreationStories. The legend states that the plant was named "Indian pipe" due to a group of chiefs quarreling without resolution, while passing a pipe around during the dispute; the Great Spirit then turned the chiefs into the plant, as they should have smoked the sacred pipe after making peace with each other. The plant is said to grow wherever friends have quarreled.
Native to #PacificNorthwest & a few other areas too.

Researchers Devise #Photosynthesis-Based Energy Source With Negative #CarbonEmissions extracting energy from the photosynthesis process of #algae
Suspended in a specialized solution, the algae forms part of a "micro #photosynthetic power cell" that can actually generate enough energy to power low-power devices like Internet of Things (#IoT) sensors.
Micro Photosynthetic Power Cell Array for Energy Harvesting: Bio-Inspired Modeling, Testing and Verification https://www.mdpi.com/1996-1073/17/7/1749
A micro-photosynthetic power cell (µPSC) generates electricity through the exploitation of living photosynthetic organisms through the principles of photosynthesis and respiration. Modeling such systems will enhance insights into the µPSC that can be employed to design real-time applications from µPSC. In this study, the bio-inspired electrical equivalent modeling of the array of µPSC is elucidated. The model is validated for array configurations of the micro-photosynthetic power cells. The developed arrayed model foresees the steady-state response at various electrical loadings. The polarization characteristics of the current-voltage (I-V) and current-power (I-P) characteristics of the array of µPSC in series and parallel, and their combinations in series and parallel connected µPSCs were validated with the experimental results. From this analysis, it is predicted that the arraying of the µPSC in the combination of series and parallel is the optimal array strategy to obtain the desired voltage and current from the µPSC such that it can be used to power real-time low and ultra-low power devices.
