Copper prices have surged in 2021. The base metal remains in high demand, much thanks to its need in green energy projects and electric cars. In May 2021, commodities analysts at Goldman Sachs called copper ‘the new oil.’ That’s because electric cars need several times more copper than their gas-powered counterparts. And power grids getting electricity from wind, solar and hydro sources also need copper—much more than the industry is currently producing. Here’s how copper became so important to the world economy and the green energy revolution.

Revival of pig tissue could pave the way for salvaging more human organs for transplant, and even bringing people back to life hours after death.
A team of researchers in the Faculty of Engineering of The University of Hong Kong (HKU) has developed a coin-sized system that can read weak electrochemical signals and can be used for personalized health monitoring and the measurement of such conditions as diabetes, cardiovascular diseases and mental health. The discovery was featured on the cover of Analytical Chemistry.
The PERfECT System—an acronym for Personalized Electronic Reader for Electrochemical Transistors—is the world’s smallest system of its kind, measuring 1.5 cm x 1.5 cm x 0.2 cm and weighing only 0.4 gram. It is easily wearable, for instance integrated with a smartwatch or as a patch, to allow for continuous monitoring of biosignals such as glucose levels and antibody concentrations in blood and even sweat.
“Our wearable system is tiny, soft and imperceptible to wearers, and it can do continuous monitoring of our body condition. These features mean it has the potential to revolutionize health care technology,” said Dr. Shiming Zhang of the Department of Electrical and Electronic Engineering, who leads the HKU WISE (wearable, intelligent and soft electronics) Research Group to develop the system.

Virginia is going from near-zero wind power to 2.6 gigawatts all at once, with the approval of a new offshore wind plan for Dominion Energy.
California is making waves with a big announcement of big plans for offshore wind, but the Golden State already hosts hundreds of wind turbines on shore. The really big news on the wind front is all the way across the country in Virginia, which has practically zero megawatts to its credit, onshore or off. That’s about to change all at once. Utility regulators in Virginia just stamped their seal of approval on a massive, Texas-sized offshore wind farm to the tune of 176 wind turbines totaling almost 2.6 gigawatts.
Wait, How Does An Offshore Wind Turbine Get To 14.7 Megawatts?
The new offshore wind farm comes under the umbrella of the Virginia-based company Dominion Energy, and we have questions.
Physicists have just caught light acting the part of ‘glue’ between atoms, in a kind of loosely bonded molecule.
“We have succeeded for the first time in polarizing several atoms together in a controlled way, creating a measurable attractive force between them,” says University of Innsbruck physicist Matthias Sonnleitner.
Atoms connect to form molecules in a variety of ways, all involving a trade of charges as a kind of ‘superglue’.
We’ve recently heard about efforts to replace some of the aggregate used in concrete with crumbled used tires. Now, scientists have succeeded in producing good quality concrete in which all of the aggregate has been replaced with tire particles.
In recent years, we’ve heard about efforts to replace some of the aggregate used in concrete with crumbled used tires. Now, however, scientists have succeeded in producing good quality concrete in which all of the aggregate has been replaced with tire particles.
Concrete consists of three parts: water, a cement which binds everything together, and an aggregate such as sand or gravel. That aggregate has to be mined from the ground, and is actually now in short supply in many parts of the world.
Discarded tires can be recycled to a certain extent, but often just end up sitting in landfills or getting burned.
The new technology comes at a time when nuclear’s contribution to the overall energy sector is fading.
