The Cities are the topic of the month here at Scientific American (and at least this week on the blogs), so I should chime in on an aspect of urban ecology that I am comfortable discussing – the effects of increased light at night on animals. [More]

Quantum communication could be an option for the absolutely secure transfer of data. The key component in quantum communication over long distances is the special phenomenon called entanglement between two atomic systems.
