Credit: Dreyer et al, Nature Communications (CC-BY-SA 4.0)Strong alternating magnetic fields can be utilized to generate a new kind of spin wave that was previously just theoretically anticipated. A team of physicists from Martin Luther College Halle-Wittenberg (MLU) achieved this for the first time. They report on their work in...
Melting glacier. credit: iStock/ fredtamashiroThe Thwaites Glacier is holding onto Antarctica's ice sheet by its fingernails, and the globe might see significant changes over the next year or two, researchers have alerted in a recently released study, CNN reported.As the world warms, giant sheets of ice near the poles have been melting off. Previously...
Researchers observed bright flares of X-ray emissions. Image credit: Dan WilkinsResearchers at Stanford University have actually located a strange pattern while seeing the X-rays from the supermassive black hole at the centre of a galaxy 800 million light-yrs away. The black hole, it seems, is spewing out these rays into the universe around it.Dan...
Tokamak geometry and the parameter evolution of a FIRE mode. a, The plasma configuration of a FIRE mode in KSTAR. Credit: Nature (2022). DOI: 10.1038/s41586-022-05008-1A team of researchers connected with several institutions in South Korea, working with two coworkers from Princeton University and one from Columbia University, has accomplished a new milestone in the development of...
Rocks created from hydrothermal vent precipitates on the seafloor. Dominic PapineauScientists get long pondered how and when the evolution of prokaryotes to eukaryotes happened. A collaborative research group from Tohoku University and the College of Tokyo may have offered some answers after discovering new kinds of microfossils dating 1.9 billion years.Details of their findings were...

Some today think they were sub-Saharan Africans. We can observe this interpretation portrayed in Michael Jackson's 1991...
When squeezed to high pressure between two diamonds (shown), a material made of carbon, sulfur and hydrogen can transmit electricity without resistance at room temperature.It is here: Researchers have reported the exploration of the first room-temperature superconductor after more than one century of waiting.The discovery evokes daydreams of futuristic technologies which could improve electronics...

DOI: 10.1073/pnas.2207449119Today, an international group of scientists led by Séamus Davis, Professor of Physics at the University of Oxford and University Cork, has announced outcomes that reveal the atomic mechanism behind high-temperature superconductors. The searchings for are released in PNAS.Superconductors are...

As it turns out, however, researchers at Microsoft, scientists at Brown University, and one professional who consulted for Disney's "Wrinkle in Time" believe the laws of physics may actually be slowly changing, complicating...
Experimental realization of a swimmer on a sphere with actuated motors on a freely rotating boom arm. Credit: Georgia TechWhen humans, animals, also machines move throughout the world, they always press against something, whether it is the ground, air, or water. Until currently, physicists thought this to be a constant, following the law of...
