Electric microbes – X-ray diffraction has been used to reveal the structure of proteins attached to the surface of the microbe Shewanella oneidensis, a species found in deep-sea anaerobic habitats. These proteins can transfer electrons making this micro-organism potentially rather interesting as an electricity-generating system. The research could allow researchers to tether bacteria directly to electrodes creating efficient microbial fuel cells or bio-batteries powered by human or animal waste. Such an advance could also …

Uranium hard drive – A new uranium-containing compound maintains its magnetic behaviour at low temperatures. The discovery could take us a step closer to magnetic memory devices with capacities thousands of times denser than current high-end hard drives.
Clouds from both sides – Atmospheric and climate models may have overlooked the fact that exactly how clouds appear to reduce the amount of sunlight available for warming the surface of the earth depends on the …
