Crystals and glasses have opposite heat driving properties, which play a fundamental role in a variety of technologies. These range from miniaturization and the efficiency of electronic devices to the recovery systems of the waste state, as well as the useful life of thermal shields for aerospace applications. The problem of optimizing the performance and…
The bursts of Type III radio are generated by means of energy electrons that propagate through the interplanetary space. These electron beams, released from the sun, travel along the Parker spiral and Langmuir waves through a kinetic instability in the electron speed distribution function. Langmuir waves generated later suffer conversion, producing a radio emission to…
Archaeologists in Germany have discovered the remains of three women of the copper age who were buried with what could have been “” illuminated baby carriers: large bags decorated with hundreds of teeth of dogs and wolf. The fabric or leather of the bags has been gone a long time ago, but the teeth of…

If the number of galaxies, the densities and properties of those galaxies and other cosmic properties, such as the temperature and the expansion rate of the universe, did not…
Note on the morphology of Cymbiapophysa Marimbai (Perafán and Valencia-Cuéllar, 2018) (Araneae: Theraphosidae) Abstract Direct examination of the cymbiapophysa marimbai holotype (Perafán and Valencia-Cuéllar, 2018) by the author confirms the presence of a cymbial process, a character that is overlooked in the original description of this species. Peñaherrera-R., P. (2025b). Note on the morphology of…
Takeways in the middle of the Milky Way The black hole supermajero called Sagittarius A* is located in the middle of the Milky Way. The observations of S2 and other stars also helped astronomers calculate the extraordinary size and mass of Sagittarius A* and weighs approximately 4.3 million solar masses. Although the entire Milky Way,…
Astronomers may be beginning to obtain products on the lava planets. These burning worlds share a density similar to Earth, but an orbit so close to their host stars that their diurnal abrasing temperatures melt the same rocks from which they are made, creating possible magma oceans that cover their surface. While Lava Mundos represent…
The potato came from a surprising mashup. Spuds are a basic, delicious food for millions worldwide, yet their origin and evolution have long been a scientific mystery. Not anymore, scientists say. The starchy vegetable emerged 9 million years ago in the forming Andes mountains — a result of natural interbreeding between an ancient tomato plant…
