Researchers create 'whirling' nano-structures in anti-ferromagnets

Inspired by the Big Bang cooling, the new finding could lead to super-fast, energy-efficient memory chips.

Scientists use trilayer graphene to observe more robust superconductivity

Scientists report successfully stacking three sheets of graphene and then twisting each of them at a magic angle to produce a three-layered structure that is not only capable of superconductivity but does so more robustly and at higher temperatures than many of the double-stacked graphene.

New quantum receiver the first to detect entire radio frequency spectrum

A new quantum sensor can analyze the full spectrum of radio frequency and real-world signals, unleashing new potentials for soldier communications, spectrum awareness and electronic warfare.

Outer Space Is a Treasure Chest of Gemstones

Scientists suspect it might be raining diamonds on Neptune and Uranus. Evidence of opal on Mars hints at a watery past. Outside our solar system, there may be rubies and sapphires too. But the gems that form within Earth still might be the most dazzling.

Dark matter: A new tool in the search for axions

Researchers have discovered a new avenue to search for axions -- a hypothetical particle that is one of the candidates of dark matter particles. The group, which usually performs ultra-high precision measurements of the fundamental properties of trapped antimatter, has for the first time used the ultra-sensitive superconducting single antiproton detection system of their advanced Penning trap experiment as a sensitive dark matter antenna.

Terahertz accelerates beyond 5G towards 6G

Researchers demonstrate wireless transmission of uncompressed full-resolution 8K video using terahertz waves, accelerating research and development of Beyond 5G towards 6G.

Quality of muon beams

A new technique has taken the first images of muon particle beams. Scientists plan to use it to assess the quality of these beams, which are being used more and more in advanced imaging applications.

On the dot: Novel quantum sensor provides new approach to early diagnosis via imaging

A phenomenon called 'oxidative stress' is seen in affected organs during the early stages of certain difficult-to-treat diseases like cancer and kidney dysfunction. Detecting oxidative stress could thus enable early diagnosis and preventive treatments. But, the in vivo measurement of oxidative stress caused by both oxidation and reduction has historically been difficult. Now, scientists have developed an advanced quantum sensor technology that can detect 'oxidative stress' non-invasively throughout the body using fluorescent imaging and MRI.

What Is the Scientific Method and How Did It Shape Science?

How careful observation, strict reasoning and clever hypotheses guided the great human endeavor of science.

Modeling the brain during pain processing

The many different sensations our bodies experience are accompanied by deeply complex exchanges of information within the brain, and the feeling of pain is no exception. So far, research has shown how pain intensity can be directly related to specific patterns of oscillation in brain activity, which are altered by the activation and deactivation of the 'interneurons' connecting different regions of the brain. However, it remains unclear how the process is affected by 'inhibitory' interneurons, which prevent chemical messages from passing between these regions.
