A striking demonstration of a means to boost the information-carrying capacity of radio waves has taken place across the lagoon in Venice, Italy. The technique exploits what is called the “orbital angular momentum” of the waves – imparting them with a “twist.” Varying this twist permits many data streams to fit in the frequency [...]

Charges on single atoms have been measured before, but capturing the dance within a complex molecule is significantly more difficult. The pioneering measurement could shed light on a range of “charge-transfer” [...]
