A recent Physical Review Letters study presents a new model for quark star merger ejecta that could resolve whether these cosmic collisions generate ordinary matter or something different.
Scientists trying to work out whether a star exploded and the resulting debris crashed into Earth 10 million years ago may be one step closer to solving the mystery. They discovered an unusual amount of Beryllium-10 (10Be) at the bottom of the Pacific Ocean, which may be explained by a supernova, an exploding star.
Chicago has quickly emerged as a hub for quantum computing, with the state of Illinois and technology companies pouring millions of dollars into developing a campus to build the world’s first commercially viable quantum computer on the city’s Southeast Side.
The terahertz (THz) band of the electromagnetic spectrum holds immense promise for next-generation technologies, including high-speed wireless communication, advanced encryption, and medical imaging. However, manipulating THz waves has long been a technical challenge, since these frequencies interact weakly with most natural materials.

Venus is often called Earth’s “sister planet” because of their similarities in size, mass, and composition. Both are rocky worlds that formed about the same time in the inner solar system; however, despite these similarities, Venus evolved into a world vastly different from Earth, with surface temperatures around 465°C, crushing atmospheric pressure 90 times greater than Earth’s and thick clouds containing sulfuric acid circling the planet. These dramatic differences between two such similar planets make Venus a fascinating subject for planetary scientists to study.
Cosmic dust—the tiny particles that help form stars, planets and the chemical building blocks of life—might be much spongier and fluffier than long assumed, according to an international group of scientists.
An article published in the journal Communications Medicine points to a correlation between disturbances in Earth’s magnetic field resulting from solar storms and an increase in the frequency of heart attacks, especially among women.

Using NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered two new exoplanets around a young sun-like star known as TOI-6109. The newfound alien worlds are slightly larger than Neptune and orbit their host in less than 10 days. The finding was presented in a paper published September 18 on the arXiv pre-print server.
The Sibiu manuscript discovered in 1961, is a collection of around 450 pages that include among many other things, details of three-stage rockets and manned rocket flight. Most of us are unaware of the fact that there are countless ancient manuscripts scattered across the globe, describing what many consider as improbable achievements of the past. What would you say If I told you that there is an ancient manuscript that dates back nearly 500 years, and describes liquid fuel, multi-stage rockets, and even manned rockets?
You’d either say I’m crazy, or it’s just fake news. *Have you noticed how people these days call out as fake news anything that they find hard to believe or goes against their belief system? Anyway, the Sibiu manuscript is real, it’s not fake news, and it does, in fact, describe—among other things— liquid fuel and multi-stage rockets, and it was officially published in the 16th century, although many believe it was written using texts that go back further in time.
The Sibiu Manuscript was found in 1961 by Doru Todericiu, a professor of Science and Technology at the University of Bucharest. The manuscript contained around 450 pages which were recovered from the archives of the city of Sibiu, in Romania. To the surprise of Todericiu, the ancient text was flooded with drawings and technical data on artillery, ballistics and detailed descriptions of multistage rockets. Referred to as the Sibiu manuscript ever since, the ancient text is believed to have been written by a man called Conrad Haas, between 1550 and 1570. Conrad Haas is believed to have been a military engineer who worked for the Kingdom of Hungary and the Principality of Transylvania. The ancient manuscript origins aren’t very clear, nor are the origins of its author who according to historians is believed to have been born in either Austrian or Transylvania and became the head of the arsenal of the Austrian Empire under King Ferdinand I.  The Sibiu manuscript, written entirely in German, was found to be a theoretical treatise on the construction of different types of weapons, including—for the first time in history—multistage rocket technology. It also includes details on the combination of fireworks with weapons, the design of fins in the shape of a hang glider as well as the creation of fuel mixtures with the use of liquid fuel. It remains a mystery whether or not Haas managed to use his designs and put into practice, but there are some who claim that a rocket launch was carried out in Sibiu in 1550, but there is no documentary evidence to support these claims. We do know from history that Johann Schmidlap, a 16th-century Bavarian fireworks maker, and rocket pioneer, was the first to experiment with two-stage and three-stage rockets around 1590. Before the discovery of the Sibiu manuscript, the earliest details of a three-stage rocket was attributed to Kazimierz Siemienowicz, a Polish specialist in artillery, who published details about rocketry in his 1650 treatise Artis Magnae Artilleriae Pars Prima. Conrad Haas wrote down a few interesting sentences in his manuscript in which he talks about the military use of rockets (translated): “But my advice is for more peace and no war, leaving the rifles calmly in storage, so the bullet is not fired, the gunpowder is not burned or wet, so the prince keeps his money, the arsenal master his life; that is the advice Conrad Haas gives.” At least four people have died and eight have been injured in the attack on a Grand Blanc Township Church of the Latter-day Saints congregation; the shooter was shot and killed by officers
Time-varying systems, materials with properties that change over time, have opened new possibilities for the experimental manipulation of waves. Contrarily to static systems, which exhibit the same properties over time, these materials break so-called temporal translation symmetry. This in turn prompts the emergence of various fascinating phenomena, including time reflection, refraction and diffraction.
