SPACE INFRASTRUCTURENew “Cosmic Concrete” Is Twice as Strong as Regular Concrete
Building infrastructure in space is currently prohibitively expensive and difficult to achieve. Future space construction will need to rely on simple materials that are easily available to astronaut. Scientists have created a new material, dubbed “StarCrete,” which is made from extra-terrestrial dust, potato starch, and a pinch of salt. It could be used to build homes on Mars.

RARE EARTH ELEMENTS (REEs)Australian Government Needs to Go ack to Basics to Build an Australian Rare-Earths Industry
China has moved well beyond an aspiration to monopolize the production of rare earths. It aims for leadership in the production of the full range of goods making use of rare earths—from electric cars to wind turbines, MRI scanners, lasers and rocket motors.

CRITICAL MINERALSThe U.S. Needs to Ditch Its America-First Approach to Critical Minerals
More and more countries with advanced economies have begun to prioritize the supply and value chains for critical minerals and rare-earth elements because of their links with advanced and low-emissions technologies. In some countries, governments have responded to the critical minerals challenge by adopting a new version of economic nationalism. But unilateral responses will not produce secure or reliable supply chains. Indeed, economic nationalism may actually aggravate the problem.

RARE EARTH ELEMENTS (REEs)Looking for Critical Minerals in Mine Waste
Mine waste is the material left over after mining. It consists of tailings, the material that remains after mined ore is milled and concentrated, as well as the topsoil, waste rock and other materials that were removed to get to the ore. Some critical-mineral commodities, like rare earth elements, are known to occur alongside more commonly mined minerals like iron or nickel. Because of this, mine-waste sites are now being revisited.

RARE EARTH ELEMENTS (REEs)U.S., China Compete for Africa's Rare Earth Minerals
African countries like the Democratic Republic of Congo have some of the largest deposits of these resources, but China currently dominates the supply chain as well as their refinement and the U.S. wants to reduce its reliance on the Asian giant.

INFRASTRUCTURE ROTECTIONCreating Buildings That Can Withstand the Most Extreme Stress Loads
Combined ballistic impacts pose a major challenge for engineers who build structures that must withstand extreme stresses. An explosion can hurtle fragments and debris at enormous velocities so they strike the surroundings. Then comes the shock wave. It’s a scary combination.

ARGUMENT: BATTERIES WARBatteries Are the Battlefield
The United States is one of many countries pursuing the clean energy revolution, and which have ramped up investment in electric vehicles manufacturing and renewable energy sources to power the shift away from fossil fuels. Christina Lu and Liam Scott write that this is an industry that has already been staked out by another power: China.

FOOD SECURITYPhosphorus Supply Is Increasingly Disrupted – We Are Sleepwalking into a Global Food Crisis
Without phosphorus food cannot be produced, since all plants and animals need it to grow. Put simply: if there is no phosphorus, there is no life. All farmers therefore need access to it, but 85% of the world’s remaining high-grade phosphate rock is concentrated in just five countries, making the global food system extremely vulnerable to disruptions.

CRITICAL MINERALSThe Global Race to Secure Critical Minerals Heats Up
The World Trade Organization last week ruled that Indonesia had no right to ban the export of nickel or to require that raw nickel ore be refined in Indonesia. Handing a comprehensive victory to the complainant, the European Union, the WTO decision highlights the clash between national security and global trade rules over critical minerals.

RARE EARTH ELEMENTS (REEs)Australia and Its Partners Must Do more to Avoid Dependence on China for Rare Earths
Low labor costs, indifference to the environmental impacts of mineral processing, and the rest of the world dropping the ball while focusing on other issues allowed Beijing to achieve global dominance of critical-minerals markets, with almost 80% control of rare earths and up to 94% of other critical minerals like magnesium. The global markets for rare-earth elements and critical minerals are shaping to be the next economic hot zone for the Chinese Communist Party—and for the security of the world’s advanced economies.

To what extent has China adhered to its pledge to not build new overseas coal power plants? What are the main concerns related to China’s ownership or control over power transmission and distribution companies in Latin America? What is the state of China’s deep- and distant-sea and seabed mining exploration activities, and to what extent does it use these activities for ulterior strategic purposes?
