This edition of our Newsletter is a testament to our collective dedication and the exciting progress we’ve achieved. The completion of our first Periodic Report marks a significant milestone, and the advancements in tetrahedrite mineral-based thermoelectric materials are not just promising -they are a lap towards a sustainable future. We’re excited to share updates on our ongoing activities, our synergistic collaborations with the EHRASE cluster and THERMOS project, and insightful technical information on thermoelectric generators. But that’s not all, join us on the Consortium Tour, where this time SGUDS and IGME-CSIC take centre stage. Plus, don’t miss the insightful interview with Doug Crane from our Scientific Advisory Board, whose expertise enriches our understanding of thermoelectrics. This edition also features the fascinating adventures of Starty, exploring the practical uses of thermoelectric devices in a narrative that’s both educational and engaging. Looking ahead, we eagerly anticipate your visit to the START booth at the upcoming 40th International and 20th European Thermoelectric Conference, ICT/ECT 2024, in Krakow. We hope this Newsletter serves not only as a source of information but also as an inspiration for continued excellence. Stay connected with us for more exciting updates from START on our website and social media channels.

Marine and terrestrial biogeochemical models are key components of the Earth System Models (ESMs) used toproject future environmental changes. However, their slow adjustment time also hinders effective use of ESMsbecause of the enormous computational resources required to integrate them to a pre-industrial equilibrium. Here,a solution to this "spin-up" problem based on "sequence acceleration", is shown to accelerate equilibration of state-of-the-art marine biogeochemical models by over an order of magnitude. The technique can be applied in a "blackbox" fashion to existing models. Even under the challenging spin-up protocols used for Intergovernmental Panelon Climate Change (IPCC) simulations, this algorithm is 5 times faster. Preliminary results suggest that terrestrialmodels can be similarly accelerated, enabling a quantification of major parametric uncertainties in ESMs, improvedestimates of metrics such as climate sensitivity, and higher model resolution than currently feasible.

Parental care in fishes varies greatly depending on the species. Some species exhibit no parental care at all, with the eggs being left to develop on their own, while others display elaborate forms of care, such as guarding the eggs, fanning them to provide oxygen, or even carrying the eggs in their mouths. These behaviors can enhance the survival of the offspring by protecting them from predators, providing oxygen, and ensuring optimal conditions for development.

Warming the Earth's Atmosphere: Causes, Effects, and Solutions The phenomenon of atmospheric warming, commonly referred to as global warming or climate change, has emerged as one of the most pressing environmental challenges of our time. It is primarily driven by human activities that increase the concentration of greenhouse gases (GHGs) in the Earth's atmosphere, leading to significant and potentially irreversible changes in climate patterns. This essay explores the causes, effects, and potential solutions to this critical issue. Causes of Atmospheric Warming The primary cause of atmospheric warming is the enhanced greenhouse effect, which occurs when certain gases in the Earth's atmosphere trap heat from the sun. The most significant greenhouse gases include carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), and fluorinated gases. Human activities, particularly since the Industrial Revolution, have dramatically increased the levels of these gases. Key contributors include: Burning of Fossil Fuels: The combustion of coal, oil, and natural gas for energy and transportation is the largest source of CO₂ emissions. Deforestation: Trees absorb CO₂, and large-scale deforestation reduces the planet's capacity to absorb this greenhouse gas, while the burning and decomposition of trees release additional CO₂. Agriculture: Agricultural practices, such as livestock farming, produce significant amounts of methane and nitrous oxide. Industrial Processes: Various industrial activities release GHGs, including the production of cement, steel, and chemicals. Effects of Atmospheric Warming The impacts of atmospheric warming are profound and widespread, affecting natural ecosystems and human societies globally. Some of the most significant effects include: Rising Temperatures: Global average temperatures have increased, leading to more frequent and intense heatwaves. This can result in health problems, reduced agricultural yields, and increased energy demand. Melting Polar Ice and Glaciers: Higher temperatures cause the melting of ice in polar regions and glaciers, contributing to sea level rise. This threatens coastal communities with increased flooding and erosion. Ocean Acidification: The absorption of excess CO₂ by the oceans leads to acidification, which adversely affects marine life, particularly organisms with calcium carbonate shells or skeletons. Extreme Weather Events: There is an increase in the frequency and severity of extreme weather events such as hurricanes, droughts, and heavy rainfall. These events can cause significant damage to infrastructure, disrupt food and water supplies, and displace populations. Ecosystem Disruption: Changes in temperature and precipitation patterns can alter habitats and affect biodiversity, leading to shifts in species distributions and the potential extinction of vulnerable species. Solutions to Mitigate Atmospheric Warming Addressing atmospheric warming requires a multi-faceted approach that combines mitigat

Harry Coumnas asserts that some individuals think teleportation is merely a fantastical concept and that human teleportation seems like science fiction in real life. However, scientists have already made headway toward the goal of human teleportation by successfully achieving quantum teleportation. He takes into account the reality that, although teleportation for humans is confined to science fiction, it is conceivable in the subatomic realm of quantum mechanics.

Taphonomy is the study of how organisms decay and become fossilized or preserved in the paleontological record. The term taphonomy (from Greek táphos, τάφος 'burial' and nomos, νόμος 'law') was introduced to paleontology in 1940[1] by Soviet scientist Ivan Efremov to describe the study of the transition of remains, parts, or products of organisms from the biosphere to the lithosphere.[2][3] The term taphomorph is used to describe fossil structures that represent poorly-preserved, deteriorated remains of a mixture of taxonomic groups, rather than of a single one.

Using deep archival observations from the Chandra X-ray Observatory, we present an analysis of linear X-ray-emitting features located within the southern portion of the Galactic center chimney, and oriented orthogonal to the Galactic plane, centered at coordinates l = 0.08◦ , b = −1.42◦ . The surface brightness and hardness ratio patterns are suggestive of a cylindrical morphology which may have been produced by a plasma outflow channel extending from the Galactic center. Our fits of the feature’s spectra favor a complex two-component model consisting of thermal and recombining plasma components, possibly a sign of shock compression or heating of the interstellar medium by outflowing material. Assuming a recombining plasma scenario, we further estimate the cooling timescale of this plasma to be on the order of a few hundred to thousands of years, leading us to speculate that a sequence of accretion events onto the Galactic Black Hole may be a plausible quasi-continuous energy source to sustain the observed morphology
