Electrons slide through the hourglass on surface of bizarre material

A team of researchers at Princeton University has predicted the existence of a new state of matter in which current flows only through a set of surface channels that resemble an hourglass. These channels are created through ...

A proposed superconductivity theory receives exclusive experimental confirmation

Superconductivity - a quantum phenomenon in which metals below a certain temperature develop flow of current with no loss or resistance - is one of the most exciting problems in physics, which has resulted in investments ...

Mirror mirror: Snail shells offer clue in unravelling common origins of body asymmetry

An international team of researchers has discovered a gene in snails that determines whether their shells twist clockwise or anti-clockwise - and could offer clues to how the same gene affects body asymmetry in other animals ...

Mapping the nuclear pore complex: 1.5 billion years of innovation

(Âé¶¹ÒùÔº)—If asked to describe the differences between humans and frogs, a child might say that one hops and rib-its while the other walks and talks. If we ask that same child how to build a frog, they will probably need ...
