Nickelates are a material class that has excited scientists because of its recently discovered superconducting ability, and now a new study led by Cornell has changed where scientists thought this ability might originate, providing a blueprint for how more functional versions might be engineered in the future.
Superconductivity was predicted in nickel-based oxide compounds, or nickelates, more than 20 years ago, yet only realized experimentally for the first time in 2019, and only in samples that are grown as very thin, crystalline films—less than 20 nanometers thick—layered on a supporting substrate material.
Researchers worldwide have been working to better understand the microscopic details and origins of superconductivity in nickelates in an effort to create samples that successfully superconduct in macroscopic “bulk” crystalline form, but have yet to be successful. This limitation led some researchers to speculate that superconductivity was not being hosted in the nickelate film, but rather at the atomic interface where the film and substrate meet.
Assessing how energy-generating synthetic organelles could sustain artificial cells.
Researchers have assessed the progress and challenges in creating artificial mitochondria and chloroplasts for energy production in synthetic cells. These artificial organelles could potentially enable the development of new organisms or biomaterials. The researchers identified proteins as the most crucial components for molecular rotary machinery, proton transport, and ATP production, which serves as the cell’s primary energy currency.
Energy production in nature is the responsibility of chloroplasts and mitochondria and is crucial for fabricating sustainable, synthetic cells in the lab. Mitochondria are not only “the powerhouses of the cell,” as the middle school biology adage goes, but also one of the most complex intracellular components to replicate artificially.
The ‘ultramassive’ black hole discovery has big implications for our future understanding of space.
Echopraxia is a book set in one of the most interesting sci-fi universes that I have covered on this channel. It is technically a sequel to Blindsight, but it is not necessary that you read Blindsight to understand Echopraxia is set in the late 21 century. About 14 years after man’s first contact with alien life.
This book brings up one of the most interesting concepts I’ve ever encountered in any sci-fi book ever. And that is the concept of the “Digital Universe” and God as a Virus. Now this is a concept that comes from the field of digital physics, which keep in mind is all theoretical. It is based on the premise that the universe is pure mathematics at its base, every event that occurs can be thought of as a kind of computation. This could mean that the universe is a simulation, but that is not necessary for the idea to work.
Cambridge researchers have discovered a new topological phase in a two-dimensional system, which could be used as a new platform for exploring topological physics in nanoscale devices.
Two-dimensional materials such as graphene have served as a playground for the experimental discovery and theoretical understanding of a wide range of phenomena in physics and materials science. Beyond graphene, there are a large number 2D materials, all with different physical properties. This is promising for potential applications in nanotechnology, where a wide range of functionality can be achieved in devices by using different 2D materials or stacking combinations of different layers.
It was recently discovered that in materials such as hexagonal boron nitride (hBN), which are less symmetric than graphene, ferroelectricity occurs when one layer slides over the other and breaks a symmetry. Ferroelectricity is the switching of a material’s electric dipole moment with an electric field, which is a useful property for information processing and memory storage.
The Big Bang may have not been alone. The appearance of all the particles and radiation in the universe may have been joined by another Big Bang that flooded our universe with dark matter particles. And we may be able to detect it.
In the standard cosmological picture the early universe was a very exotic place. Perhaps the most momentous thing to happen in our cosmos was the event of inflation, which at very early times after the Big Bang sent our universe into a period of extremely rapid expansion.

CRISPR Is The Future.
Welcome to the future!
It is the year 2050, and the world is facing a crisis. Climate change has caused widespread devastation, and the planet’s resources are dwindling. Famine and disease are rampant, and humanity is on the brink of collapse. But amidst the chaos, a new hope emerges.
Scientists have devised a way of fabricating a complex structure, previously found only in nature, to open up new ways for manipulating and controlling light.
The structure, which naturally occurs in the wing scales of some species of butterfly, can function as a photonic crystal, according to a new study by researchers at the University of Birmingham. It can be used to control light in the visible range of the spectrum, for applications for lasers, sensors, and also devices for harvesting solar energy.
Their computational study, published in Advanced Materials, demonstrates that the complex gyroid structure can be self-assembled from designer colloidal particles in the range of hundreds of nanometers.
