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 […]

Alfred Russel Wallace (1823-1813) is especially known as one of the discoverers of evolution by natural selection. However, among his various contributions to the development of modern biology we can also consider the British naturalist as the father of biogeography: […]

Zircon grains came from ancient continent
Grains of zircon found on the island of Mauritius may have come from the crust of an ancient continent beneath the Indian Ocean. The grains formed almost 2 billion years ago, but the island […]

All of us know that animals use camouflage and mimicry as strategies to protect themselves from predators. Many examples have become famous with many TV documentaries showing, among others, foxes and rabbits that in higher latitudes are white to be […]

“Native” water once existed on the Moon
A new analysis of lunar soil samples from NASA’s Apollo missions has found evidence that the moon in its early days may have contained “native” water. The findings, which were published in the […]

Robert Hooke discovered the cell in 1665. Plenty of years passed until the human being, in less than three decades, went from elucidate DNA structure (1953) to control artificially the genetic expression of a living cell. Thorough knowledge of the […]

“Photonic crystals” is the name that was given to periodic arrangements of materials with different refractive indexes. This name derives from the analogy between the behavior of photons in these materials and the one of electrons in the periodic structure […]

 
Humans can build and use the most sophisticated tools. One of the reasons is the configuration of our hands, which enable us to hold items in a very convenient way. But further than that, we can actually grab items […]
