You come back home really tired after a long day at work and you decide to take that loooong bath you’ve been waiting for. You stay in the water for some time and suddenly you realize your fingers are wrinkling. Oh boy, that is telling you that you’ve been there for a while and reminds […]

Horses have distinct facial expressions much like humans Despite facial structure differences, horses have similar facial expressions to humans and use these expressions as social cues. Using their Equine Facial Action Coding System, researchers found that horses have 17 distinct facial movements as opposed to human faces, which have 27. The Christian Science Monitor Physicists […]
In the standard representation of the periodic table, we find below two separated rows of elements. Their chemistry and electronic configuration belong to a group three element, so what these two separated rows really mean is that in this representation of the table they are all located on top lanthanum and actinium, three-dimensionally building a […]
Plants are sessile organisms, which means they can´t move around. Of course, they have some types of movements like turning towards the sun but the place where the seed germinates the plant will stay during their entire life cycle. Obviously, this fact has important consequences on how plants respond upon variations of their surrounding environment […]

A prolific star-making dwarf galaxy The Hubble Space Telescope has spotted a busy dwarf galaxy filled with bright, new stars and making even more. NGC 1140 resides in the constellation Eridanus, about 60 million light-years from Earth. Scientists at the European Space Agency say it can’t keep up its robust star production for long because […]
There are two main groups of mammalian brains. Lissencephalic brains have a smooth surface and can be found, for example, in mice, rats or manatees. Gyrencephalic brains, by contrast, have deeply folded brains with gyri (ridges) and sulci (depressions or furrows). They are found, for example, in cats, dogs, pigs, whales, elephants and primates including […]
When two superconducting materials are separated by a very thin (less than 10-8 m or 10 nanometers) layer of an insulating material at very low temperature some peculiar electrical effects can be detected called Josephson effects. If normal conducting metals are separated by such a barrier in that conditions it is possible for a small […]
The role of molecular hydrogen (dihydrogen) in reactions of organic and inorganic chemistry is very well known . One can mention numerous reactions playing the key role in biochemistry, like for example processes in microorganisms, or the commonly known addition of H 2 to organic compounds. It is worth to mention that dihydrogen as an […]
Triangles are, definitely, among the most used mathematical objects. One of the reasons is that they are simple (actually the smallest polygon). Another very important reason is that they are rigid, which is the property behind the many structures composed by triangles we can see in our daily life. But, surprisingly enough, triangulations are not […]

Windbots for the exploration of gas giants NASA is looking to windbots to possibly explore Jupiter, Saturn, Uranus and Neptune, all gas planets that can’t be explored with a rover like those prowling Mars. NASA is financing research into windbots, which would catch a ride on the chaotic gases and gather information that way. Tech […]
