source:Borneo BulletinA handful of postage-stamp nations in the South Pacific launched an uphill battle this week against the deep-sea mining of unattached, fist-sized rocks rich in rare Earth metals.The stakes are potentially enormous.Companies keen to scrape the ocean floor five to six thousand metres below sea level stand to earn billions harvesting manganese, cobalt, copper and nickel currently used to build batteries for electric vehicles.But the extraction process would disfigure what may be the most pristine ecosystem on the planet and could take millennia, if not longer, for nature to ...

source:electrive.comThe automotive supplier Mahle has developed what it claims is the most enduring electric motor. The special feature: thanks to a new cooling concept, the SCT (Superior Continuous Torque) is supposed to be able to operate at high power for an unlimited period of time.The supplier refers to the cooling concept as a “technological leap”. According to Mahle, this is an integrated oil cooling system that not only takes care of the cooling itself, but at the same time also enables the use of the resulting waste heat in the overall system of the vehicle.According to the “latest me...

source:physicsworldAn axial Higgs mode has been spotted within the collective quantum excitations of a solid material. Kenneth Burch at Boston College and colleagues in the US and China, discovered the quasiparticle cousin of the Higgs boson in a relatively simple tabletop experiment carried out at room temperature.In 2012, the discovery of the Higgs boson at CERN’s Large Hadron Collider confirmed a prediction made nearly 50 years earlier about the mechanism by which some fundamental particles acquire mass. The Higgs mechanism is triggered by spontaneous symmetry breaking and was originally de...

source:Lawrence Livermore National LaboratoryNewswise — Using naturally occurring and engineered proteins and bacteria, Lawrence Livermore National Laboratory (LLNL) scientists and collaborators will separate and purify rare-earth elements so they can be used in the defense sector.Under the Defense Advanced Research Projects Agency (DARPA) Environmental Microbes as a BioEngineering Resource (EMBER) program, the team was awarded an initial $4 million in funding R&D in Phase 1 with an option for up to an additional $9M based on program performance in follow-on phases. The team will leverage ...
