We show that seafloor-cables, when combined with ultra-stable interferometry, can act as arrays of environmental sensors for earthquakes, ocean currents and other ocean signals, with potentially game-changing applications in Earth monitoring.

The distribution of Bacillus subtilis in a pine-forest soil has been investigated by using the fluorescent-antibody technique and dilution plating. In the acid, mineral horizon of the soil, the organism occurred mainly in the vegetative condition, wh

LiAlCl 4 /SO 2 electrolytes were observed, by infrared spectroscopy, to contain hydroxychloroaluminate impurities, which would react with metallic lithium in a battery. These hydroxyl contaminants were removed by reaction with chlorine, and the produ
