Now that Saturn is visible in the sky at dusk, it is fairly easy to spot its biggest satellite Titan with a small telescope. Don’t expect nothing more than a bright point in the sky but it is provocative to imagine the Huygens probe descending into its thick atmosphere in the beginning of 2005. It […]
In the previous article of this series starred by ribonucleic acids, we found out about how an RNA molecule is able to regulate complex cascades of molecular events as critical as to decide the fate of a whole cell lineage. But RNA is also capable of other intriguing functions, and one of the most recently […]

Hope springs eternal: “Pandora’s Promise” and the truth about nuclear energy So why would environmentalists of all people support nuclear power? What changed these people’s minds? Two things, primarily. The Curious Wavefuntion Making and Breaking Compulsive Behaviour When scientists have scanned the brains of people with obsessive-compulsive disorder, they’ve seen more neural activity in areas […]
Have you ever observed how a drop of coffee dries? As water evaporates, its suspended particles are deposited in a ring-like fashion in a phenomenon known as the coffee-ring effect. Obviously, this effect is undesirable in the numerous practical applications that require a uniform coating. However, the way to avoid it has remained unknown. The […]
A dear biologist friend once complained to me that the Basque verb hausnartu is used to mean both “to ruminate”, and “to ponder over”. He saw this as an example of very bad language behavior that should not be encouraged. I replied by noting that this can hardly be a whim of our native tongue […]
Just a few years ago, nanoparticles broke into almost every laboratory in the world in one way or another. It marked a boom in nanoscience and nanotechnology. The demand for these new ultrafine particles, halfway between the bulk scale and the molecule scale, increased in such a way that sometimes there was even a shortage […]
Quantum mechanics, a term continously repeated during the last twenty years, related with everything, only deeply known and understood by a few, is therefore covered in a mystic and magic halo. Halo profited by some to trick people using any sort of elfish terms containing “quantum” as a key word. To rid out of such […]
All of the giant planets of our Solar System, except Uranus, emit more energy in the long wavelengths than what they receive from the Sun in the short wavelengths. This excess of energy was generated in the early stages of the planetary formation and it is being radiated slowly to space as the planets keep […]

Graphene shown to produce ultrashort laser pulses Researchers have discovered that graphene can absorb light over a broad range of wavelengths, allowing it to be used to create ultrashort laser pulses of color. The discovery could mean that graphene, a thin, strong conductive material, could be used to create small, economical ultrashort-pulse lasers used in […]
Quantum computing is one of the most interesting fields of study nowadays, both from theoretical and pragmatic point of views. A universal quantum computer can potentially solve certain problems, as factorizing numbers, much faster and with fewer resources than a classical one . This developing technology is based on the use of quantum mechanics as […]
