Communication through chemistry: 'Fuses' convey information for hours

We currently transmit information electronically; in the future we will most likely use photons. However, these are not the only alternatives. Information can also be transmitted by means of chemical reactions. George M. Whitesides and his colleagues at Harvard University have now developed a concept that allows transmission of alphanumeric information in the form of light pulses with no electricity: the 'infofuse'.

Using carbon nanotubes in lithium batteries can dramatically improve energy capacity

Batteries might gain a boost in power capacity as a result of a new finding from researchers at MIT. They found that using carbon nanotubes for one of the battery's electrodes produced a significant increase - up to tenfold - in the amount of power it could deliver from a given weight of material, compared to a conventional lithium-ion battery.
