"With each interaction, Alexa is training to hear better, to interpret more precisely, to trigger actions that map to the user's commands more accurately, and to build a more complete model of their preferences, habits and desires. What is required to make this possible? Put simply: each small moment of convenience - be it answering a question, turning on a light, or playing a song - requires a vast planetary network, fueled by the extraction of non-renewable materials, labor, and data. The scale of resources required is many magnitudes greater than the energy and labor it would take a human to operate a household appliance or flick a switch. A full accounting for these costs is almost impossible, but it is increasingly important that we grasp the scale and scope if we are to understand and govern the technical infrastructures that thread through our lives. III The Salar, the world's largest flat surface, is located in southwest Bolivia at an altitude of 3,656 meters above sea level. It is a high plateau, covered by a few meters of salt crust which are exceptionally rich in lithium, containing 50% to 70% of the world's lithium reserves. 4 The Salar, alongside the neighboring Atacama regions in Chile and Argentina, are major sites for lithium extraction. This soft, silvery metal is currently used to power mobile connected devices, as a crucial material used for the production of lithium-Ion batteries. It is known as 'grey gold.' Smartphone batteries, for example, usually have less than eight grams of this material. 5 Each Tesla car needs approximately seven kilograms of lithium for its battery pack. 6 All these batteries have a limited lifespan, and once consumed they are thrown away as waste. Amazon reminds users that they cannot open up and repair their Echo, because this will void the warranty. The Amazon Echo is wall-powered, and also has a mobile battery base. This also has a limited lifespan and then must be thrown away as waste. According to the Ay

Throughout the Holocene, societies developed additional layers of administration and more information-rich instruments for managing and recording transactions and events as they grew in population and territory. Yet, while such increases seem inevitable, they are not. Here we use the Seshat database to investigate the development of hundreds of polities, from multiple continents, over thousands of years. We find that sociopolitical development is dominated first by growth in polity scale, then by improvements in information processing and economic systems, and then by further increases in scale. We thus define a Scale Threshold for societies, beyond which growth in information processing becomes paramount, and an Information Threshold, which once crossed facilitates additional growth in scale. Polities diverge in socio-political features below the Information Threshold, but reconverge beyond it. We suggest an explanation for the evolutionary divergence between Old and New World polities based on phased growth in scale and information processing. We also suggest a mechanism to help explain social collapses with no evident external causes.

One way to harness solar energy is by using solar electricity to split water molecules into oxygen and hydrogen. The hydrogen produced by the process is stored as fuel, in a form that can be transferred from one place to another and used to generate power upon demand. To split water molecules into their component parts, a catalyst is necessary, but the catalytic materials currently used in the process, also known as the oxygen evolution reaction, are not efficient enough to make the process practical.

"Design thinking is an abductive approach to complex problem solving that leverages the designer's empathetic mindset in order to understand people's unarticulated needs and identify opportunities for solutions. This is a human-centered innovation process that can be applied to a wide range of challenges: design thinking can be used to create everything from products and services to business models and processes."

Any entity or system that we call 'living' will eventually die. This holds at any scale, from cellular level to ecosystems, and even our socio-economic, financial and technological domains. To understand why, it is best to look at a such a system as a infrastructure for a specific saturation process. Large organisms/systems are actually huge ensembles of interacting (and saturating) sub-processes, but here we just consider the 'top-level' saturation process. (At a high, technical abstraction level, this is always the saturation-process of entropy production, and the system is some local maximum of this, but you can read about this in our other publications).

The New Siberian Islands were the birthplace of the MOSAiC floe: the sea ice in which the research vessel Polarstern is now drifting through the Arctic was formed off the coast of the archipelago, which separates the East Siberian Sea and the Laptev Sea to the north of Siberia, in December 2018. Sediments, and even small pebbles and bivalves, were incorporated into the ice during the freezing process, which the ongoing melting process has brought to light on the surface of the MOSAiC floe. This is an increasingly rare phenomenon as today, most "dirty ice" melts before it even arrives in the Central Arctic. These are among the main findings of a study that MOSAiC experts have published now in the journal The Cryosphere, and which will provide the basis for numerous upcoming scientific assessments.

Beginning in the late 1970s, China's economy delivered the largest growth spurt in recorded history. Striking discontinuity between recent outcomes and the economic experience of the prior 200 years invites portrayal of recent events as a "China miracle" that requires neither economic nor historical analysis. This overlooks deep institutional constraints arising from authoritarian rule and its supporting elite networks and fails to recognize the link between central government weakness and the origins of the recent boom. In both the pre-1949 treaty ports and in the aftermath of the Cultural Revolution, the retreat of central control enabled episodes of economic openness and dynamism built upon 'bottom up' initiative and decentralized innovation. Historic legacies that shape political structures and individual behavior will continue to influence China's economic trajectory.

"What these examples have in common is that they illustrate two of the key tasks of the social sciences: to measure important social variables over time and space, and to identify the social mechanisms that lead to variation in these variables. There are large problems of methodology and conceptual clarification that need to be addressed in both parts of this agenda. On the side of measurement, we have the problems of arriving at consistent and revealing definitions of economic wellbeing, using incomplete historical sources to reconstruct estimates of prices and wages, and using a range of statistical methods to validate and interpret the results. And on the explanatory side, we are faced with the difficult task of reconstructing social processes and forces in the past that may have powered the changes we are able to document, and with the task of validating the hypotheses we have put forward on the basis of historical evidence."

"Right now, the biggest impediment to thinking about the future of the humanities is that, thanks to this entrenched narrative of decline-because we've been crying wolf for so long-we already think we know what's going on. The usual suspects-student debt, postmodern relativism, vanishing jobs-are once again being trotted out. But the data suggest something far more interesting may be at work. The plunge seems not to reflect a sudden decline of interest in the humanities, or any sharp drop in the actual career prospects of humanities majors. Instead, in the wake of the 2008 financial crisis, students seem to have shifted their view of what they should be studying-in a largely misguided effort to enhance their chances on the job market. And something essential is being lost in the process."
