Researchers build first modular quantum brain sensor, record signal
A team of scientists at the University of Sussex have for the first time built a modular quantum brain scanner, and used it to record a brain signal. This is the first time a brain signal has been detected using a modular quantum brain sensor anywhere in the world. It's a major milestone for all researchers working on quantum brain imaging technology because modular sensors can be scaled up, like Lego bricks.

Extraordinary new material shows zero heat expansion from 4 to 1,400 K
Australian researchers have created what may be one of the most thermally stable materials ever discovered. This new zero thermal expansion (ZTE) material made of scandium, aluminum, tungsten and oxygen did not change in volume at temperatures ranging from 4 to 1400 Kelvin (-269 to 1126 °C, -452 to 2059 °F).

AI “Magic” Just Removed One of the Biggest Roadblocks in Astrophysics
Using neural networks, Flatiron Institute research fellow Yin Li and his colleagues simulated vast, complex universes in a fraction of the time it takes with conventional methods. Using a bit of machine learning magic, astrophysicists can now simulate vast, complex universes in a thousandth of the time it takes with conventional methods. The new approach will help usher in a new era in high-resolution cosmological simulations, its creators report in a study published online on May 4, 2021, in Proceedings of the National Academy of Sciences.

World's first video recording of a space-time crystal
A team of researchers has succeeded in creating a micrometer-sized space-time crystal consisting of magnons at room temperature. With the help of an ultra-precise X-ray microscope, they were able to capture the recurring periodic magnetization structure in a movie. The research project “Real space observation of magnon interaction with driven space-time crystals” was published in Physical Review Letters.

We found the first evidence of a major shift in Earth's magnetic poles. It may help us predict the next
About 41,000 years ago, something remarkable happened: Earth’s magnetic field flipped and, for a temporary period, magnetic north was south and magnetic south was north.

Scientists Realize Efficient Generation of High-Dimensional Quantum Teleportation
In a study published in Physical Review Letters, the team led by academician GUO Guangcan from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) made progress in high dimensional quantum teleportation. The researchers demonstrated the teleportation of high-dimensional states in a three-dimensional six-photon system.

Flow of time is just an illusion
Many good stories begin with this magical phrase, but have you ever thought that "what is the story of time?" Does time exist? We always say time can be spent, time is money, we waste time, we are trying to save time, but what do we really know about the time? Is time an illusion? According to physicist Brian Greene, "all the time exist at once in spacetime"

What Is a Particle?
It has been thought of as many things: a pointlike object, an excitation of a field, a speck of pure math that has cut into reality. But never has physicists’ conception of a particle changed more than it is changing now.

“Holy Grail” Sought for More Than a Century: Researchers Synthesize Room Temperature Superconducting Material
Compressing simple molecular solids with hydrogen at extremely high pressures, University of Rochester engineers and physicists have, for the first time, created material that is superconducting at room temperature. Featured as the cover story in the journal Nature, the work was conducted by the lab of Ranga Dias, an assistant professor of physics and mechanical engineering.
