Full article below. #Thermally #insulating #textiles based on #aerogels have been previously developed inspired on polar bear fur. Now polar bear fur sebum sheds some #light into #anti-#icing materials. Nature helps us solve many of the issues we are facing if we pay #attention. This manuscript mentions #compounds in #polar #bear sebum that could be alternatives to anti-icing materials. This knowledge could inspire the development of alternatives to #per-and #polyfluoroalkyl substances or #PFAs. It highlights the use of #GC-#MS, #LC-#MS, #LC-#MS/MS and #NMR for #analysis and the importance of #phospholipids and #branched #fatty #acids in nature. #Chemistry is all around us. A study of the polar bear sebum #microbiome might be coming soon. Afterall, #microorganisms live on skin and fur and they have been associated with the release of #metabolites. It is only logical to expect that #microbes have a role to play in the composition of polar bear sebum. This manuscript #highlights #teamwork and the fact that we should #protect not only our natural #resources and the species that live on #earth but also our collective #wisdom and #knowledge. Each one of us has so much to #contribute! And so much to #learn! Thank you Science Magazine! 🌻 https://lnkd.in/eBPUh-Zp

Tardigrades, often referred to as water bears, possess an extraordinary ability to endure the vacuum of space. They accomplish this feat by entering a state known as cryptobiosis, during which they halt their metabolism and become nearly indestructible. This adaptation enables them to survive extreme temperatures, radiation, and the harsh conditions of space. These resilient creatures have been found in almost every environment explored, from the Arctic to the equator, intertidal zones to the deep ocean, and the tops of forest canopies. Their widespread presence is closely tied to their remarkable survivability. This tardigrade was discovered in a sample from an SBR analysis, conducted to evaluate the nutrient composition and optimisation potential of the treatment plant.

In 2020, I theorized the phenomenon of biomass creation and evolution, with the aim of creating resilient and sustainable crop models. The self-fertility of the Earth quickly emerged as one of the keys to understanding this incredibly complex and, above all, living cycle, to which we are vitally linked. Here is an excerpt from my theory of The Anatomy of Fertility (2020). I invite you to follow the HORTIS page and share your opinions !
There is a deep connection between mammalian anatomy and our planet's ecological systems. By understanding the complexity and interconnectedness of biological and ecological systems, we then understand the absolute necessity of preserving our planet and its incredible process of creating life. Here we share with you an excerpt from the theory of the Anatomy of Fertility (2020) by Maxime Grosse (Founder of Hortis). We invite you to share your opinions ! ****************** Fertility Anatomy -Brain / Inner Core : Luminous synapses. -Arteries & Veins / Outer Core : Distribution network. -Throat / Upper Mantle : Filters space elements. -Skeleton / Lower Mantle : Support and movement. -Muscle / Continental Crust : Robust muscle fibers. -Liver & Kidneys / Oceanic Crust : Filtration and purification. -Blood / Magma : Circulating vital flow. -Heart / Magma Chamber : Essential pump, vibrant at the center. -Urine / Water : Elimination and renewal. -Hair / Plants : Filter, thermal regulation, humidity control, and permeability. -Bacteria / Living Organisms : Immune system. -Intestinal Wall / Biosphere - Hydrosphere : Digestion and absorption. -Intestines / Lithosphere - Kerosphere : Transformation and assimilation. -Skin / Thermosphere - Mesosphere - Stratosphere - Troposphere : Interactions and reactions.

The discovery of Dark Oxygen on the ocean floor, as reported by Dr. Hashem Al-Ghaili, is reshaping our understanding of the origins of life on Earth. These mysterious nodules were found during the measurement of Oxygen consumption by seafloor organisms, hinting at alternative processes beyond traditional photo-synthesis. This groundbreaking find opens the door to the potential development of complex life forms in unconventional environments, potentially influencing the evolution of life as we know it today. To delve deeper into this fascinating discovery, watch the video provided herein. #DarkOxygen #OriginOfLife #ScienceDiscovery

Scientists have discovered how certain plants use 'leaf cooling' to survive extreme heat. In this process they evaporate water to regulate temperature, similar to how humans sweat. 💧 Learn more about this research at https://buff.ly/40xbLTZ. #nauresearch #leafcooling #climateadaptation #plantscience #trees

Pineal gland "magnetosensitivity" to static magnetic fields is a consequence of induced electric currents (eddy currents). Only the pineals of animals exposed to the automatically activated field responded with a reduced activity of the rate-limiting enzyme serotonin-N-acetyltransferase, lower melatonin levels and increases in serotonin and 5-hydroxyindole acetic acid. -- During the past decade, a number of reports indicated that the mammalian pineal gland is magnetosensitive in terms of spatial orientation. This indication is based on observations that artificial alterations of the direction of the earth's magnetic field (MF) markedly decreased the gland's capability to synthesize melatonin. These findings, however, seem paradoxical since animals as well as humans experience such alterations whenever they turn their heads. Therefore, the potential of the pineal for sensing magnetic fields was re-investigated. Only the pineals of animals exposed to the automatically activated field responded with a reduced activity of the rate-limiting enzyme serotonin-N-acetyltransferase, lower melatonin levels and increases in serotonin and 5-hydroxyindole acetic acid. Hence, MF exposure itself did not affect the pineal. Rather, induced eddy currents in the animals, resulting from rapid On/Off transients of the artificially applied MF, are most likely the explanation. https://lnkd.in/gCY2gwn6
