Disks can store information for billions of years A new five-dimensional data storage method has been developed that researchers say can last up to 13.8 billion years, withstand extreme heat and hold all sorts of information. The data are encoded into minuscule nanostructures in small glass discs. The Verge New carbon structure can hold liquids […]

The interactions between moving charges and magnetic fields can be quite complicated; more if we consider the quantum effects. One example is the collection of Hall effects. There are analogues of these effects for spin and the detection of the most sophisticated one in graphene, where, at least, it should not be strong, is something […]

Energy sources in the modern world are mostly based on fossil fuels like oil, natural gas, and coal. They all share two main characteristics of the utmost importance for their economic analysis. First, they are depletable resources. The amount of reserves for these resources may be small or large, but definitely not large enough to […]

All we know about fire under Earth´s gravity must be questioned in microgravity. In fact, most of the well-known characteristics of fire behavior are driven by the effects of gravity. That´s why the science of combustion in low-gravity environments is an important field of knowledge for NASA studies when evaluating spacecraft safety. And, contrary to […]

Gravitational waves predicted by Einstein heard by LIGO Gravitational waves from the collision of two black holes about 1.3 billion years ago have been detected by Laser Interferometer Gravitational-Wave Observatory, or LIGO, confirming a prediction Albert Einstein made a century ago in his general theory of relativity. The sound came through as a chirp first […]

Quantum mechanics was founded upon the existence of the wave–particle dualism of light and matter, and the enormous success of quantum mechanics, including the probability interpretation, seems to reinforce the importance of this dualism. But how can a particle be thought of as “really” having wave properties? And how can a wave be thought of […]

Behavioral lateralization is a significant field of study because it may provide insights into the initial origins of lateralization. Different and very diverse organisms show lateralization. The best known is handedness, a better (faster or more precise) performance or individual preference for use of a hand but it is not unique, many creatures, including humans […]

Though I’m making a break in the brief story of skepticism I have been telling in my past entries, we will not lose contact with our friends the demons; if in that story we were talking about the most philosophical one of them ( Descartes’ Evil Demon ), this time our initial protagonist is another […]

Unusual nasal dome allowed ancient beast to trumpet like a dinosaur An ancient wildebeest-like creature that lived during the Ice Age had an unusual skull shape that enabled it to bellow like a dinosaur, according to researchers who found the skull fossils on what is now Kenya’s Rusinga Island. Rusingoryx atopocranion, which lived between 75,000 […]

The band theory of metals has been subjected to experimental tests many times and is now the accepted model of the behaviour of conductors and insulators. But it has to be modified when it comes to superconductivity. Electrical resistance is due to collisions of the electrons (whether treated as particles or waves) with impurities, imperfections […]
