Meningitis is rare in newborns but often dramatic. For the first time, researchers have developed a preventive approach that stops harmful bacteria in their tracks before transmission even occurs.
Researchers at ETH Zurich have structured a wafer-thin silicon membrane in such a manner that it can direct mechanical waves along specific paths. Such structures offer interesting opportunities for converting unwanted vibrations into usable energy or for processing mechanical signals.
Researchers at ETH Zurich have, for the first time, created certifiably perfect random numbers using a quantum experiment. These can be used, for instance, for encrypting messages.
