DNA can store more than just genetic code A team of researchers added seven synthetic nucleobases to DNA’s current four-letter code, thereby expanding the innate ability of the double helix to store a variety of information, findings in the journal Nano Letters reveal. The study suggests this method may be a solution to sustainable data […]
Some metals, alloys and transition-element salts exhibit a form of magnetism called antiferromagnetism. This occurs below a certain temperature, named after Louis Néel, when an ordered array of atomic magnetic moments spontaneously forms in which alternate moments have opposite directions. There is therefore no net resultant magnetic moment in the absence of an applied field […]
Contemporary philosophy of science was, at least during its first decades (those of the glorious Vienna Circle), a kingdom of radically empiricist and positivist intellectuals: scientific knowledge had to be obtained and tested mainly through experiment, and everything that could not be robustly grounded on experimental observations was just dangerous speculation and metaphysics. The connections […]
Human activities impact significantly on the environment we live. The human society has been experiencing extreme weather conditions frequently that indicate a systematic climate shift. Almost every place in the world has set records of extreme temperatures. This trend of extreme weather has been warned by scientists to be possibly a result of excessive human […]
Brainwave data offers clues on moment of death Data captured at the time of death of an 87-year-old epilepsy patient indicated that the human brain may be designed to coordinate the transition to death, activating brainwaves most commonly associated with memory flashbacks. “[A]lthough our loved ones have their eyes closed and are ready to leave […]
Deep below the Spanish side of the Pyrenees, we find the LSC (Laboratorio Subterráneo de Canfranc – Canfranc Underground Laboratory), where the NEXT experiment is taking place. Its goal is one of the remaining holy grails of particle physics: the proof that the neutrino is its own antiparticle, a result with profound meaning not only […]
Cod “supergenes” have shed light on how they respond to overfishing, and these supergenes could make them more resilient to other environmental changes. That’s according to a new study published by scientists in Norway. This could be good news, in that cod have genetic architecture in place that will permit them to respond to climate […]
A new type of cell has been identified in the heart of several organisms, from the zebrafish to mouse and human hearts. This new type of cell, called “nexus-glia” by its discoverers, as it forms a net around the heart, not only appears to possess some characteristics from these cells, but it is also related […]
Atomic clock may help with more precise measurements Physicists have created an atomic clock that is so accurate it won’t lose a second for 300 billion years. Researchers say the clock’s precision will help them better understand difficult to measure things as gravitational waves and dark matter. Space.com Map charts Milky Way’s leftovers from galaxy […]

Nanothreads are one-dimensional nanomaterials composed of a primarily sp 3 hydrocarbon backbone, typically formed through the compression of small molecules to high pressures. In 2015, it was found that the slow room-temperature compression of benzene produced crystalline , one-dimensional polymers composed of diamond-like bonds. These diamondoid materials that border nanotubes and polymers are predicted to […]
