A new technique may make it easier for researchers to create real-time images of microscopic samples by considering the waves that propagate through sample surfaces as light interacts with them. Go to Source Analysis suggests that the two pioneers of quantum mechanics, Niels Bohr and John von Neumann, may have had more similar views than previously thought regarding the nature of quantum systems, and the classical apparatus used to measure them. Go to Source Established around 100 B.C., and lasting until its fall between the seventh and eighth centuries, Teotihuacan was one of the largest ancient cities in the world, it is one of the most incredible constructions in America, at Teotihuacan we find evidence that the builders had incredible knowledge in Mathematics, Geology, Astronomy, and Engineering. Check […] Using the Hubble Space Telescope (HST), astronomers have performed spectrophotometric observations of an eclipsing white dwarf–brown dwarf binary known as WD1032+011. Results of their observational campaign, published September 10 on the preprint server arXiv, yield important information regarding the nature of this system. Go to Source Data collected by the SAMURAI spectrometer at RIKEN’s RI Beam Factory (RIBF) in Japan recently led to the detection of a rare fluorine (F) isotope, known as 30F. This has opened interesting possibilities for the study of rare nuclear structures and corresponding phases, which could in turn help to test various physics theories. Go to […] In the beginning of the Norse cosmos, there existed an eternal Void, known as Ginnungagap. Out of this nothingness sprang Yggdrasil, a huge Ash tree. Its newly emerging branches held two primordial worlds; Niflheim, a world of ice & frost, and Muspellheim, a realm of molten fire. When a spring erupted from Nifelheim (known […] A new catalog providing information on millions of distant galaxies, which determines their distances with unprecedented precision over a field of view and depth never before explored, has been published today. Go to Source An interaction between an elliptical galaxy and a spiral galaxy, collectively known as Arp 107, seems to have given the spiral a happier outlook thanks to the two bright “eyes” and the wide semicircular “smile.” The region has been observed before in infrared by NASA’s Spitzer Space Telescope in 2005. However, NASA’s James Webb Space […] Americans are famously fond of their guns. So it should come as no surprise that a team of NASA scientists has devised a way to “shoot” a modified type of sensor into the soil of an otherworldly body and determine what it is made out of. That is precisely what Sang Choi and Robert Moses […] Is it time for space lasers yet? Almost. Go to Source In September 1859, the same year that Darwin published “On the Origin of Species,” telegraph systems across Europe and North America stopped working and started sparking, leading to fires in some cases. Go to Source What’s the best way to wake a giant after a long nap? “Very carefully, and with a lot of planning,” said a grinning John Galambos. He was the project director for the Proton Power Upgrade project, or PPU, at Oak Ridge National Laboratory until his retirement in July after more than 40 years at the […] In a few picoseconds (trillionths of a second), a small, thin piece of copper momentarily becomes dense plasma, specifically a state called warm dense matter, warm being a relative term—the metal is nearly 200,000 degrees Fahrenheit. With the short duration of a high-powered laser pulse, copper shifts from a solid state to a plasma state […] Quantum entanglement is a fascinating feature of quantum physics—the theory of the very small. If two particles are quantum-entangled, the state of one particle is tied to that of the other, no matter how far apart the particles are. This mind-bending phenomenon, which has no analog in classical physics, has been observed in a wide […] Researchers have demonstrated a new optical atomic clock that uses a single laser and doesn’t require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks without sacrificing accuracy and stability, this advance could lead to high-performance atomic clocks that are compact and portable.
