Wearable devices that monitor physical well-being and fitness are incredibly popular. The number sold is expected to increase from 17.7 million in 2014 to more than 40 million this year.1

Personally, I use the Jawbone UP24 and have found it very useful for keeping track of my daily steps and sleep patterns. Most of these devices come set with a default goal of 10,000 steps a day, which is a number commonly associated with a basic or moderate level of fitness.

Un experimento diseñado originalmente para probar las habilidades visuales de los pulpos y las sepias, ha dado a los investigadores de la Universidad de Bristol una visión sin precedentes de la capacidad humana para percibir la luz polarizada, un súper sentido que la mayoría de nosotros ni siquiera sabemos que tenemos.

Todos estamos familiarizados con el color y el brillo, pero hay una tercera propiedad de la luz, la "polarización", que nos dice la orientación en la que las ondas de luz están oscilando.

Un profesor de la Universidad de Wyoming ha hecho un descubrimiento que responde a una pregunta de casi 100 años de antigüedad sobre el movimiento subterráneo del agua, con implicaciones para la agricultura, la hidrología, la ciencia climatológica y otros campos.

Después de décadas de esfuerzo, Fred Ogden, Director en Jefe de Ingeniería, Medio Ambiente y Recursos Naturales del Departamento de Ingeniería Civil y Arquitectura de la Escuela Haub de Medio Ambiente y Recursos Naturales de la Universidad de Wyoming, y un equipo de colaboradores, publicaron sus hallazgos en la revista Water Resources Research esta primavera.

While many electric vehicle owners will find it irritating and annoying to be hit with adverts when charging their vehicles, is this a sign of the times? The fact that many larger companies are willing and prepared to pay for advertising space on “free” charging devices seems to indicate that the marketing industry believes the sector is here to stay. So, will advertising be a help or a hindrance to the industry going forward?

Until the electric vehicle industry cracks the “mass market” it is vital that the cost of services and products is kept as low as possible. There will come a point when costs will have to rise, services will be chargeable and the whole dynamic will be very different than what we see today but, in the meantime, is advertising on “free” charging stations really a hindrance?

As Greece prepares for its referendum, Takis Grigoriou takes Greece to task for its highly polluting lignite power sector, its ditching of a successful solar program in favour of more coal, the minimal insulation in its buildings that locks in high fuel bills, and Syriza's failure to tackle these issues. The good news? Greece's latest €1.4bn coal project looks like going unfunded.

Instead of phasing out lignite Greece opted to engage in a long battle to preserve the ailing industry while putting an abrupt end to solar energy development by blocking new applications.
