170 new rogue exoplanets detected Around 170 free-floating exoplanets have been detected in the latest findings by a collaboration of astronomers around the globe. The rogue exoplanets were located around 420 light-years from Earth in the Upper Scorpius OB section of the Milky Way. Gizmodo Lifeforms may exist in Venus’s clouds Ammonia may counteract sulfuric […]
Some materials have special universal properties protected against perturbations. Such properties are theoretically described by topology, a branch of mathematics concerned with the properties of geometrical objects that are unchanged by continuous deformations. So-called topological insulators are electronic materials that have a bulk band gap like an ordinary insulator but have conducting states on their […]
Poland is planning to build a wall along its border with Belarus, primarily to block migrants fleeing the Middle East and Asia. But the wall would also divide the vast and ancient Białowieża Forest, a UNESCO World Heritage site which harbours more than 12,000 animal species and includes the largest remnants of primeval forest that […]
Entanglement is the purest and most important quantum property. Unlike classical systems, quantum objects can be connected independently of their distance and if we perform a measurement in one part the other one is affected instantaneously. Intuitively, this can be considered a violation of relativity because this theory states that no information can travel faster […]
Forests were cleared by Neandertals 125K years ago Neandertals cleared a large forest into open land in what is now Germany about 125,000 years ago. Researchers analyzed a pair of lake basins and found hints that the hominids were the first to make significant changes to their landscapes my molding their surroundings. Science News Evidence […]
Transition metal dichalcogenides (TMDs) are layered compounds which can be thinned down to the single-layer limit. While mechanical exfoliation generates atomically thin TMD flakes possessing an area of a few square microns, chemical and physical methods provide high-quality monolayers on large-area substrates, which are suitable for actual technological applications. TMDs are a class of van […]
When the most massive stars die, they collapse to form some of the densest objects known in the Universe: black holes. They are the “darkest” objects in the cosmos, as not even light can escape their incredibly strong gravity. Because of this, it’s impossible to directly image black holes, making them mysterious and quite perplexing […]
We live in a time when scientific applications are growing by leaps and bounds. This exponential growth has been possible, among other tools, thanks to the application of nanotechnology. There is something that nanotechnology has taught us: In science, size matters. When studying matter at nanometric levels, we find that the properties are completely different […]
Massive exoplanet detected in distant binary system Scientists have spotted a huge exoplanet orbiting a pair of stars roughly 325 light-years away that was observed via a direct image. The exoplanet resides in b Centauri, which is hotter than any other known system and is incredibly heavy, weighing in at about 11 times the mass […]
Electrons do not move around nuclei in defined curved orbits. Our current understanding of how electrons are to be found in atoms and molecules is based on clouds of probability called orbitals as it is not possible to give a definite path for an electron. Thus, an orbital is a region in which an electron […]
