Author: Kepa Ruiz-Mirazo, Permanent Researcher, University of the Basque Country (UPV-EHU) The effort of mapping ignorance in biology is especially frustrating –or, if the mood and attitude of the scientist afford it, especially motivating– because solid, definite answers remain minimal compared to the amount of open issues and uncertainties that new discoveries in this field […]

Natural non-wetting structures, particularly lotus leaves (Fig. 1a), have inspired the development of synthetic liquid-repellent surfaces. These surfaces rely on the formation of a stable air–liquid interface, but present limited repellency to oils with high contact angle hysteresis, failure under pressure and inability to self-heal. The paper by Wong et al. presents a novel approach […]

It is well known that an accurate and energetic laser shot can melt, ionize and excite the material in which the light is focused, creating very bright plasmas after the interaction. Valuable information can be obtained from the light emitted by the plasma, such as the elemental composition of the material itself or the environment […]
