Sunlight is the most important energy source of Earth. All earthlings live thanks to the ability of plants and bacteria to transform solar energy into chemical one. As sunlight is a free, and practically unlimited, energy source it is easy […]

Nowadays, our role as consumers controls most of our spare time. We find delight in looking for that object that symbolizes our values, our aesthetic categories, or at least the kind of thing we are comfortable with. We might well […]

 
The human brain is arguably the most fascinating organ found in nature. Its complexity has been known since Santiago Ramón y Cajal pioneering work showed the central nervous system (CNS) was a contiguous neuronal network where neuron is the […]

 

 
Some jellyfish species are beautifully fluorescent in the dark ocean, emitting light from different parts of their bodies in a process that is thought to help them to warn off predators. The molecular biology behind this process of […]

 
Approximately 90% of world’s electricity is generated in turbines moved by hot steam, which, unfortunately, operate only at 30 to 40 percent efficiency. This means that around two thirds of the total energy input is lost into the environment […]

Materials science is becoming more and more an interdisciplinary field in which almost every traditional subject has its say. Disciplines such as biology, medicine, computational design, architecture or even music, painting or sculpture converge on this open-minded host. As a […]

Perhaps the most repeated words in the last few years when talking about graphene – since scientists Geim and Novoselov were awarded the Nobel Prize in Physics in 2010 for their groundbreaking experiments – are “the material of the future”. […]

When in April 1911 Kamerlingh Onnes and coworkers measured that the electrical resistivity of mercury suddenly vanished at 4.2K, they could not believe it. They repeated the experiment several times looking for a short circuit that could explain the weird […]

We all know the story of that Swiss engineer who came up with the hoop-and-loop fastener system (also known under the brand name Velcro) just by paying attention to the burdock burrs stuck in his clothes and his dog’s […]

Bicycles are usually regarded as the most sustainable mean of transport for urban environments. Now, when talking about sustainability, there are usually two different discussions: on the one hand, there is energy sustainability, as the fossil fuels won’t last forever […]
