Quantum computing is in all likelihood the 21st century’s great computer revolution. What is IBM doing to make the quantum dream a reality?
A superconductivity theory proposed by a Würzburg physics team has been validated in an international experiment that showed Cooper pairs display wave-like distribution in Kagome metals. The finding will enable new technological applications such as superconducting diodes.
Have you ever wondered what it would be like to upload your mind to a computer? To have a digital copy of your personality, memories, and skills that could live on after your biological death? This is the idea behind whole brain emulation, a hypothetical process of scanning a brain and creating a software version of it that can run on any compatible hardware. In this video, we will explore the science and challenges of whole brain emulation, the ethical and social implications of creating digital minds, and the potential benefits and risks of this technology for humanity. Join us as we dive into the fascinating world of whole-brain emulation!

The world’s first brain prosthesis has passed the first stages of live testing.
The microchip, designed to model a part of the brain called the hippocampus, has been used successfully to replace a neural circuit in slices of rat brain tissue kept alive in a dish. The prosthesis will soon be ready for testing in animals.
The device could ultimately be used to replace damaged brain tissue which may have been destroyed in an accident, during a stroke, or by neurodegenerative conditions such as Alzheimer’s disease. It is the first attempt to replace central brain regions dealing with cognitive functions such as learning or speech.
“This breakthrough enhances astronaut safety and makes long-term Mars missions a more realistic possibility,” said Dr. Dimitra Atri.
How will future Mars astronauts shield themselves from harmful space radiation? This is what a recent study published in The European Physical Journal Plus hopes to address as a pair of international researchers investigated what materials could be suited for providing the necessary shielding against solar and cosmic rays that could harm future Mars astronauts. This study holds the potential to help scientists and engineers better understand the mitigation measures that need to be taken to protect astronauts during long-term space missions.
For the study, the researchers used computer simulations to create Mars-like conditions, whose surface temperatures and pressures are much smaller than Earth’s, along with Mars completely lacking a protective magnetic field that provides our planet with protection from space radiation. Through this, the researchers tested a variety of materials to ascertain their effectiveness in shielding astronauts from space radiation.

A multi-institutional team of scientists in the United States, led by physicist Peng Wei at the University of California, Riverside, has developed a new superconductor material that could potentially be used in quantum computing and be a candidate “topological superconductor.”
The most recent email you sent was likely encrypted using a tried-and-true method that relies on the idea that even the fastest computer would be unable to efficiently break a gigantic number into factors.
Quantum computers, on the other hand, promise to rapidly crack complex cryptographic systems that a classical computer might never be able to unravel. This promise is based on a quantum factoring algorithm proposed in 1994 by Peter Shor, who is now a professor at MIT.
But while researchers have taken great strides in the last 30 years, scientists have yet to build a quantum computer powerful enough to run Shor’s algorithm.
U.S. Naval Research Laboratory (NRL) scientists confirm the identification of a new class of semiconductor nanocrystals with bright ground-state excitons, a significant advancement in the field of optoelectronics, in an article published in the American Chemical Society (ACS) journal ACS Nano.
The groundbreaking theoretical research could revolutionize the development of highly efficient light-emitting devices and other technologies.
Generally, the lowest-energy exciton in nanocrystals is poorly emitting, earning the name “dark” exciton. Because it slows the emission of light, the dark exciton limits the performance of nanocrystal-based devices like lasers or light-emitting diodes (LEDs). Scientists have long sought to overcome the dark exciton.
