  • New quantum microscope shows electrons moving in slow motion

    07/23/2024 4:58:11 PM PDT · by Jonty30 · 17 replies ^ | July 21, 2024 | By Knowridge
    Physicists at the University of Stuttgart, led by Professor Sebastian Loth, have developed a groundbreaking quantum microscope that can record the movement of electrons at the atomic level with incredibly high spatial and temporal resolution. This new method could significantly advance the way scientists develop materials. Their findings have been published in the journal Nature Physics. “With our new method, we can see things that no one has ever seen before,” says Prof. Loth, the Managing Director of the Institute for Functional Matter and Quantum Technologies at the University of Stuttgart. “This allows us to answer questions about electron movements...

    A patented experimental propellantless propulsion drive is finally ready to go to space, according to its inventor, a veteran NASA scientist with decades of expertise in electrostatics. [Multiple Videos at Site] Dr. Charles Buhler, the technology’s creator, says the propulsion system may represent a working version of Quantized Inertia, a theory first proposed by University of Plymouth professor Mike McCulloch. The proposition has been subjected to criticism from mainstream scientists in the past because it seemingly violates Newton’s third law of motion. The controversial technology, which The Debrief covered in April, is privately owned by Exodus Propulsion Technologies and is...

    The galaxy PJ0116-24, located 10 billion light-years away from Earth, appears to exhibit characteristics that contradict the standard view that galaxy mergers are required to produce such intense luminosity.The groundbreaking findings, which are detailed in a newly published paper in Nature Astronomy, seem to point to the occurrence of rapid star formation in HyLIRGs, revealing that it can occur through internal processes. The discovery presents new challenges to existing notions held by astronomers about how such formations occur...In the past, it was believed that the intense luminosity produced by HyLIRGs was exclusively the result of mergers between galaxies, which result...

    While the “Epoch of Reionization” sounds like the title of a sci-fi novel destined for a Hugo award, this very real era of the universe featured the first light from the very first stars. Before this epoch, the universe was nothing more than a dark void filled with a fog of primordial hydrogen gas—and then, suddenly, there was light. For decades, scientists have searched for a source of radiation powerful enough to have cleared away this fog and introduced light into the universe. Now, an international team of scientists have analyzed the first faintest galaxies ...

    Electron neutrinos have been experimentally observed for the first time during recent experiments by physicists at CERN, which produced proton-proton collisions at the facility’s Large Hadron Collider (LHC). Neutrinos are neutral subatomic particles possessing almost no mass. First detected in 1956, they possess 1/2 integral spin like all fermions and rarely react with normal matter except through the weak force. Neutrinos come in three different varieties, associated with electrons, muons, and tau particles. Due to their sparring interactions with matter, all three types of neutrinos are regarded as being among the most elusive particles in the universe. Despite this, physicists...

The new imagery reveals the appearance of this celestial object as it would have looked when the universe was less than a billion years old, offering a detailed view of the quasar’s spectrum and host galaxy. Obtained with Webb’s NIRSpec instrument, the new imagery of quasar PJ308–21 reveals its spectrum with an uncertainty of less than 1% per pixel despite the object’s incredible...

    Scientists believe a slowing or reversing inner core could potentially affect Earth's magnetic field. At the center of the Earth lies a solid metal ball that rotates independently of our spinning planet. Scientists have debated the inner core's rotation speed and direction. However, new research points to the inner core varying speed in recent years. However, researchers are not exactly sure if there are any effects from the inner core slowing down or reversing. Danish seismologist Inge Lehmann discovered the ball-shaped inner core in 1936. The inner core is buried approximately 3,220 miles deep inside Earth. The solid metal ball...

    In its first year, the Biden administration launched a fast-track Scientific Integrity Task Force, intended to “lift up the voices of Federal scientists of many perspectives and backgrounds” and put scientific integrity “paramount in Federal governance for years to come.” The task force took a “whole-of-government” approach to ensuring the scientific integrity of federally funded research and included representatives from the 21 federal agencies that maintain scientific-research programs. For those with a high pain threshold, the final report may be seen here. Prominent among the move’s critics have been the Council on Governmental Relations (a consortium of research universities) and...

    One of the surprising discoveries of the Webb telescope involves an early population of compact red galaxies at redshift above 7, a time when the Universe was 20 times younger than it is today. The galaxies are redder than expected from their cosmological redshift, indicating additional reddening by a layer of dust. Some of these galaxies contain as much mass in evolved stars as our own Milky Way galaxy. Nevertheless, they are a hundred times smaller in radius, of an order of a few hundred light years. These compact galaxies manifest an increase by a factor of a million in...

    String theory scientists studying the behavior of high energy particles say they have stumbled upon a mathematical “hack” that revealed a whole new way to represent the irrational number Pi. While the research is purely theoretical, the duo behind the Pi hack says this kind of theoretical work holds rewarding potential. The researchers also believe their work could lead to a number of potential breakthroughs in the future, similar to how theoretical breakthroughs made by physicists nearly a hundred years ago resulted in technological advancements decades later. AFTER 4,000 YEARS, PI IS STILL A MYSTERY Defined as the ratio of...

    A star is dead? Keep your eyes on the skies, stargazers: NASA has predicted that the much-anticipated “once-in-a-life-time” star explosion — or nova — will be visible to the naked eye sometime this summer, per a recent press release. “It’s incredibly exciting to have this front-row seat,” said Dr. Rebekah Hounsell, an assistant research scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Dubbed T Coronae Borealis or the “Blaze Star,” the celestial event is located 3,000 light years away and is comprised of a white dwarf, an “Earth-sized” remnant of a dead star. The starburst’s mass, meanwhile, is...
