A team of researchers from the University of Tasmania has found evidence of microplastics in ice cores collected off the coast of Antarctica. In their paper published in the journal Marine Pollution Bulletin, the group describes ...
Vehicles moving at hypersonic speeds are bombarded with ice crystals and dust particles in the surrounding atmosphere, making the surface material vulnerable to damage such as erosion and sputtering with each tiny collision. ...
