Date Time Magnetism Drives Metals to Insulators in New Experiment Like all metals, silver, copper, and gold are conductors. Electrons flow across them, carrying heat and electricity. While gold is a good conductor under any conditions, some materials have the property of behaving like metal conductors only if temperatures are high enough; at low temperatures, they act like insulators and do not do a good job of carrying electricity. In other words, these unusual materials go from acting like a ...

Date Time New Material Could Harvest Water All Day Long Micro-engineered, bioinspired design allows the material to collect moisture from cool fog as well as generating and collecting steam under sun Tiny structures inspired by the shape of cactus spines allow a newly created material to gather drinkable water from the air both day and night, combining two water-harvesting technologies into one. The material, a micro-architected hydrogel membrane (more on that later), can produce water through ...

Between the tsunami and the magnitude 7.5 earthquake that caused it, some 4,340 people were killed, making it the deadliest earthquake that year. The tsunami’s waves reached around six meters high, which was a shock to geophysicists who had believed that earthquakes along a strike-slip fault could only trigger far small...
