Auditory processing disorder (also known as central auditory processing disorder or CAPD) is a condition that makes it hard for kids to recognize subtle differences between sounds in words. It affects their ability to process what other people are saying.
Gallium is a solid metal at room temperature, but it melts in your hands. 00:09. When gallium is in its liquid state, if feels like cold melted solder in your hands. 00:33. Melting gallium onto aluminum makes the aluminum brittle enough to break with your fingers.
Scientists have invented a new material they say has the highest melting point of any known material. They calculate it would melt at 4,400 degrees Kelvin (4,126Â°C). This property would make it a strong candidate for replicating the fictional metal adamantium used to make Wolverine's claws in X-Men, pictured above.
