Scientists say data transmitted by the Messenger spacecraft provide compelling support for the notion that Mercury harbors abundant water ice and other frozen volatile materials in its permanently shadowed polar craters. Given its proximity to the Sun, the existence of frozen water is counter-intuitive, but the tilt of Mercury’s rotational axis is almost zero, meaning […]
A tiny contraption made by trapping organic molecules between metal nanoparticles has successfully generated electricity from heat; an achievement that the researchers believe could lead to more efficient ways to directly convert heat into electricity. Around 90 percent of the world’s electricity is created through the indirect conversion of heat, but inefficient conversion means that […]
