Recently, we ran a piece including the views of well-known science writer John Horgan who talked about a bizarre element of quantum physics confirmed by recent experiments-- that it appears as if there´s no knowledge apart from observers' minds.Theoretical physicist Sabine Hossenfelder is decidedly not happy with that approach:" Physicists have revealed that objective...

Clauser and Anton Zeilinger, during a press...
Droplets of silicon, used to illustrate movements similar to those of quantum particles. Aleks LabudaA solid is made of particles that are, more or less, locked in an ordered framework. On the other hand, a fluid is made of particles that can flow freely around and past each other. However, imagine atoms that stay...
Credit: BBC UK.The quantity of time it takes a light particle to pass a hydrogen molecule was measured by a team of researchers to produce the smallest unit of time ever. A trillionth of a billionth of a 2nd is the unit of measurement known as a zeptoseconds. That consists of a decimal point,...
Illustration of the experiment. 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...

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...
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...
