Superconductivity is the property of certain materials that can conduct electric currents with no resistance. This quantum phenomenon is still shrouded in mystery, and until now has been limited to very low temperatures. Yet all this could soon change.

High-energy 'sun goddess' particle opens possibilities for new physics, exciting scientists
"I am personally excited to have found a new mystery in science to solve."
Space.com
Over the years, scientists have managed to unveil the existence of quite a few intriguing particles, pushing the entire field of physics forward with each discovery. There's the "God Particle" for instance, aka the Higgs Boson that grants all other particles their masses. There's also the so-called "Oh My God!" particle, an unimaginably energetic cosmic ray.  But now we have a new particle in town. It's named  the "sun goddess" particle  —  and is fittingly extraordinary.  This particle has an energy level one million times greater than what can be generated in even humanity’s most powerful particle accelerators; it appears to have fallen to Earth in a shower of other, less energetic particles. Like the "Oh My God!" particle, these bits come from faraway regions of space and are known as cosmic rays. The particle has been dubbed "Amaterasu" after Amaterasu Ōmikami, the goddess of the sun and the universe in Japanese mythology, whose name means "shining in heaven." And just as its mythological namesake is shrouded in mystery, so too is the Amaterasu particle. Its discoverers, including Osaka Metropolitan University researcher Toshihiro Fujii, don’t know where the particle came from or indeed what it is. They also still aren't sure what kind of violent and powerful process could have given rise to something as energetic as Amaterasu.

Limits for quantum computers: Perfect clocks are impossible
There are different ideas about how quantum computers could be built. But they all have one thing in common: you use a quantum physical syst
nanotechnologyworld

The research team was able to show that since no clock has an infinite amount of energy available (or generates an infinite amount of entropy), it can never have perfect resolution and perfect precision at the same time. This sets fundamental limits to the possibilities of quantum computers.

So happy to finally share this shot with you: a conjunction of the ISS and the moon. This shot required meticulous planning and precise timing to achieve, and the full image (in the second post in the thread) is one of my all-time favorites. CR:AM

sometimes you run into something that just overturns your understanding and builds a new, more coherent picture. this is one of them.

they taught us about diffraction theory at uni - Fresnel, Fraunhofer all of that, we did experiments with lasers - but it never occurred to me to analyse lenses in terms of diffraction. it makes so much sense now! i was never entirely satisfied by the ray approximation to light, so seeing what's really going on in the lightfield and how you can use a diffraction plate as a lens, with each ring contributing higher order Fourier terms to the image, is like. crazy cool.

Tumblr users will hear their mothers say for years that eating healthier and going on walks will help with their anxiety/depressive episodes then be surprised when they try it and it actually works

Cartesian dualism has fucked up people's perception of who they are as living creatures so much that they can't possibly fathom that taking care of your body and giving it the vitamins it needs to function will in fact improve your psychological state. Your brain isn't independent of your body. It's connected and cannot be separated from it. If you don't care for your body well enough it will take a toll on your psyche. It's supposed to be that way. Your brain is telling you your body needs to be taken care of

Twisting two-dimensional atomic sheets: A key to new materials for advanced technologies
The way light interacts with naturally occurring materials is well-understood in physics and materials science. But in recent decades, resea
nanotechnologyworld

A collaborative research team led by Bo Zhen of the University of Pennsylvania has unveiled a new approach that directly engineers atomic structures of material by stacking the two-dimensional arrays in spiral formations to tap into novel light-matter interaction. This approach enables metamaterials to overcome the current technical limitations and paves the way for next-generation lasers, imaging, and quantum technologies. Their findings were recently published in the journal Nature Photonics.
