The first direct evidence of antihydrogen atoms falling into the Earth's gravitational field shows that they are subjected to gravity in the same way as normal matter. When a ball is thrown into the air, the Earth's gravitational force causes the ball to fall back to the ground. [more…]
As a result of nuclear fission, many short-lived isotopes are formed. It has been difficult to understand what they look like. Electron scattering is the industry standard for studying the internal structures of atomic nuclei. Other techniques include nuclear reaction [more…]
The bonding of quarks to each other to form protons, neutrons and atomic nuclei is such a strong force that this is the name of this force. The strong force carried by gluon particles is responsible for all fundamental forces of nature. [more…]
The properties of a material may consist of a structure formed by the rotation of two or more linear defects around each other. Defects such as dislocations, where order is disrupted, occur in systems composed of ordered components such as crystals. [more…]
Researchers have carried out a new study using a metallic grid and infrared light. A light-matter coupling regime in which the local coupling strength can be 3,5 times greater than the average global coupling strength of the material [more…]
Imagine trying to tune a radio to a specific station, but encountering static noise and competing signals from your own device. Evidence of incredibly rare events that could shed light on the formation and structure of matter in the universe [more…]
Imagine being in a crowded room with a cacophony of speakers and being able to concentrate on or block out the conversation in a specific 2D space. To do this, grasping and manipulating an acoustic environment requires [more…]
SLAC National Accelerator Laboratory's Linac Coherent Light Source, an x-ray free electron laser, is operating for the first time after an upgrade that will enable it to produce one million x-ray pulses per second. Twenty years [more…]
Numerous subatomic particles called neutrinos play an important role in the structure of the universe. These barely perceptible particles, once thought to have no mass, now appear to have mass. This [more…]
The force that pushes atoms from the hot side of a material to the cold side is demonstrated by the continuous dragging of microscale patterns on a surface. A significant temperature across a microcircuit in a device such as a mobile phone [more…]
D-Wave Systems, a Canada-based world leader in quantum computing systems, software and services, has announced some preliminary findings from the test chip it designed to characterize the fluxonium superconducting qubits it plans to use. [more…]
New research reveals graphene's unusual phonon spectrum with remarkable completeness. During crystallization, atoms are separated into broad energy bands. The electrical properties of the crystal are determined by this level spread, but this is not the only [more…]
The great dispute over the rate of expansion of the universe deepens with the James Webb Space Telescope. The Hubble tension is a unique conundrum that is the subject of one of the greatest and most contentious cosmic debates of our time. This [more…]
Astronomer Carl Sagan, best known as the creator and host of the original Cosmos television series, was a consummate science communicator. Sagan, who was also a prolific writer, published The Demon-Haunted World. [more…]
With the help of small magnetic rods and a rotating magnetic field, scientists were able to mimic the undulating motion of hair-like structures on cell surfaces. Thanks to the coordinated fluctuation of hair-like structures known as cilia, [more…]
Future observations of high-energy neutrinos at the LHC may reveal new information about tau neutrinos, the strong force, or possibly new physics. To detect light, uncharged neutrinos, scientists have used large, massive [more…]
A new set of equations that underpin computer research captures the dynamic interaction of electrons and vibrations in crystals. Although a crystal is a highly ordered structure, it is never at rest because it is at absolute zero. [more…]
A brand new satellite was launched from Earth on September 6 with the aim of informing us about the dynamics of hot plasma flows in the universe. The X-Ray Imaging and Spectroscopy Mission (XRISM) satellite, launched from the Tanegashima Space Center in Japan, detects galaxy clusters. [more…]
The binding energy and lifetime of hypertriton, a particle that can shed light on the structure of neutron stars, were determined by researchers. The Higgs boson, created by colliding high-energy protons, was discovered at the Large Hadron Collider (LHC) in 2012. [more…]
The printing press is called the most important invention of the last thousand years. This honor has often been given to Johannes Gutenberg, a 15th-century German craftsman. However, 78 years after Gutenberg printed the first copy of the Bible. [more…]
Using a new symmetry-based categorization, researchers can describe open, many-body quantum systems that exhibit quantum chaos. Both theorists and experimenters are fascinated by quantum systems consisting of large numbers of particles and the strange phenomena they exhibit. [more…]
Toothed and shaggy pigs roam freely in the forests of Germany and Austria. Although these game animals appear to be in good condition, some of their meat contains radioactive cesium that makes it dangerous to consume. scientists [more…]
A new study in BESSY II examines the occurrence of skyrmions in ferrimagnetic thin films of dysprosium and cobalt, using high spatial resolution and real-time analysis. This is precision with skyrmions of suitable materials in the future. [more…]
Researchers have developed a micrometer-thin battery that can power smart contact lenses and can be charged with a saline solution. Researchers from NTU Singapore have developed a smart contact that can store electricity when immersed in a saline solution. [more…]
In less than a decade, the self-taught physicist learned basic mathematics and started creating quantum algorithms. Sola Mahfouz was 16 years old and could hardly do addition and subtraction. Three years of physics, philosophy [more…]
Over the centuries, humans have created models of the gigantic and mysterious universe. These approaches provide users with more tangible objects to explore, from celestial globes depicting constellations to computer-based models of dark matter. Bose-Einstein condensates and [more…]
Ever since Isaac Newton and Christiaan Huygens first discussed the nature of light in the 17th century, scientists have explored whether light can be better understood as a wave or as a particle, even at the quantum level. [more…]
Experts believe that ultracold atoms trapped in an optical lattice, a periodic array of capture fields created by lasers, can perform quantum computing. This lattice must also be scalable and quantum [more…]
The chaotic energy gradient in a quantum gas out of equilibrium is captured by an experimentally derived equation of state. Turbulent systems, such as ocean waves and financial markets, are affected by wind and globally significant, respectively. [more…]
A study led by Timothy Gray at the Department of Energy's Oak Ridge National Laboratory may have discovered an unexpected change in the structure of the atomic nucleus. What binds nuclei together, how protons and neutrons interact [more…]
