“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 journal Nature Geoscience, go against prevailing theories that the moon formed from the debris of […]

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 because of the friction coefficient that exists between the skin of our hands and the surface […]

New fabric may increase access to water in deserts A team of scientists say they’ve created a piece of fabric that can collect water from fog and release the liquid when conditions are warmer. Researchers coated a piece of cotton fabric with the polymer PNIPAAm, creating sponge-like material. The fabric could be used to increase […]

We will address a recent article by Jaillet and Porta (Institut de Robòtica i Informàtica Industrial, IRI), which reveals new practical applications of highly-abstract mathematical entities. When it comes to robots, we can’t forget that their fundamental goal is always somehow related to moving stuff. Arm robots as those found in the automotive industries are […]

Proteins perform most of the daily work of the cell, they catalyse most of the biochemical reactions, initiate and mediate the electrical signals in our neurons and form an important part of the structure of our bodies. Formed by up to several thousand amino acids (from a set of 20 different types) chained one after […]

Electronics on paper At the moment the costs are still too high for them to be used in things like business cards or package labels, but remarkable advances in materials science and simpler fabrication methods are setting the stage for a whole new breed of cheap, bendable, disposable, and perhaps even recyclable electronics. And some […]

Your molar roots are leftovers from Homo erectus Adult human molar roots form for at least a year before erupting from the gum line, according to research published in the journal PLoS ONE. Researchers say the majority of the formation of teeth has evolved to keep up with longer human lifespans, except for the adult […]

Could Earth be constantly crashing through dark matter? Scientists are looking to new techniques to search for evidence that the Earth is constantly breaking through walls of dark matter. Researchers are acting on a theory that dark matter, made up of weakly interacting massive particles, are tied up in domain walls, which they liken to […]

High speed trains are the best example of vehicles that, although operating at somehow extreme conditions, are very comfortable. And by comfort I mean that the vibration level that passengers feel is relatively low. The components that allow this level of comfort are the pneumatic springs, torus-shaped rubber elements filled with pressured air. Their behaviour […]

Anyone can find an exoplanet A team of volunteer amateur astronomers has discovered evidence of 42 alien planets. The volunteers were sorting through NASA data as part of the Planet Hunters crowdsourcing program. Professional astronomers have yet to confirm the proposed planets.
