A new ground motion model that more accurately simulates earthquakes and explosions

Map of the western US study area showing the topography/bathymetry of the WUS256 field (outer thick black line), major physiographic regions named (black lines, Fenneman & Johnson, 1946), plate boundaries (red lines), hotspots (yellow diamonds, Müller et al. , 1993) and the Pleistocene and Holocene volcanic centers (yellow squares and circles, respectively, World Volcanism Program … Read more

New study overturns 100-year understanding of color perception

Credit: Pixabay/CC0 Public Domain A new study corrects an important error in mathematical 3D space developed by Nobel Prize-winning physicist Erwin Schrödinger and others, and used by scientists and industry for more than 100 years to describe how your eye distinguishes one color from another. The research has the potential to enhance scientific data visualizations, … Read more

New quantum vortices with tetrahedral symmetries have been discovered in a superfluid

1). c–g ferromagnetic phase-2 (FM2) and -1 (FM1), uniaxial nematics (UN), biaxial nematics (BN), and toroidal magnetic phases (C), with four Majorana points. The discrete Majorana polymorphic symmetries of a square and a tetrahedron for BN and C are easily recognizable. The entire behavior of the order parameter symmetries is visualized in a spherical harmonic … Read more

Physicists switch the magnetic state using spin current

The illustration shows the unconventional charge of shift spin in a quantum material with a low symmetry crystal structure. (Left) Model showing the crystal structure of WTe2, where axis A and axis B are labeled. The crystal is stationary (unchanging) when the BC (alternating current) mirror process. (Top right) When the charging current (shown by … Read more

New model sheds light on day/night cycle in global ocean

Phytoplankton blooms in the World Ocean. Credit: NASA Goddard Phytoplankton are the basis of all life on this planet. Understanding how these photosynthetic organisms interact with the ocean environment is important to understanding the rest of the food web. Despite this, computer models of the biochemistry of the global oceans usually do not include the … Read more

What happens when black holes die?

What is arguably his most important contribution to science, Stephen Hawking He suggested that black holes could leak a form of radiation that causes them to gradually recede, eventually ending their lives in a massive explosion event. This radiation, later called “Hawking radiation”, inadvertently causes a problem at the junction general relativity And the Quantum … Read more

The first ever discovery of gas in a disk around the planet

Scientists studying the young star AS 209 have detected gas in a circumplanetary disk for the first time, indicating that the star system may harbor a very small Jupiter-mass planet. Scientific images from the research (right) show point-like emissions of light coming from empty vacuoles in a highly organized seven-ring disk (left). Credit: ALMA (ESO/NAOJ/NRAO), … Read more
