Sun 14 Sep 2014. First 500 GHz photon switch built as a result of four years of research. It opens a fundamentally new direction in photonics with far-reaching potential consequences for the control of photons in optical fiber channels. Specifically, the new technology could be implemented for photon sensors that operate in fields that were previously not deemed possible. An example is a receiver that could detect a handful of photons but very slowly – with the time delay between such pulses on the order of nanoseconds, not picoseconds (one nanosecond equals 1,000 picoseconds). Another example: long-scale, locally-controlled four-photon mixing may trigger a multi-frequency photon avalanche, meaning that a few-photon signal could induce massive pump photon annihilation.

Wed 10 Sep 2014. Nuclear waste eaters - Scientists discover radioactive waste-eating bacteria. Tiny single-cell organisms discovered living underground could help with the problem of nuclear waste disposal, say researchers. Although bacteria with waste-eating properties have been discovered in relatively pristine soils before, this is the first time that microbes that can survive in the very harsh conditions expected in radioactive waste disposal sites have been found.

Thu 31 Jul 2014. Solar energy: New Dyes help harvest broader light. A new dye-sensitized solar cell absorbs a broad range of visible and infrared wavelengths. Dye-sensitized solar cells rely on dyes that absorb light to mobilize a current of electrons and are a promising source of clean energy. Scientists have now developed zinc porphyrin dyes that harvest light in both the visible and near-infrared parts of the spectrum. More

Wed 30 Jul 2014. No increased risk of cancer for children living near Sellafield or Dounreay NPP. Children, teenagers and young adults living near two British nuclear power stations since the 1990s are not at an increased risk of developing cancer, according to a detailed analysis of decades of data by Oxford University researchers.
