Magnetic topological insulators are an exotic class of materials that conduct electrons without any resistance at all and so are regarded as a promising breakthrough in materials science. Researchers have achieved a significant milestone in the pursuit of energy-efficient quantum technologies by designing the ferromagnetic topological insulator MnBi6Te10 from the manganese bismuth telluride family. The amazing thing about this quantum material is that its ferromagnetic properties only occur when some atoms swap places, introducing antisite disorder.

Atomic nuclei accelerated close to the speed of light become dense walls of gluons known as color glass condensate (CGC). Recent analysis shows that CGC shares features with black holes, enormous conglomerates of gravitons that exert gravitational force across the universe. Both gluons in CGC and gravitons in black holes are organized in the most efficient manner possible for each system's energy and size.

A team including physicists has for the first time detected subatomic particles called neutrinos created by a particle collider, namely at CERN's Large Hadron Collider (LHC). The discovery promises to deepen scientists' understanding of the nature of neutrinos, which are among the most abundant particles in the universe and key to the solution of the question why there is more matter than antimatter.

How light interacts with matter has always fired the imagination. Now scientists for the first time have demonstrated the ability to manipulate single and double atoms exhibiting the properties of simulated light emission. This creates prospects for advances in photonic quantum computing and low-intensity medical imaging.

Researchers have devised a new concept of superconducting microwave low-noise amplifiers for use in radio wave detectors for radio astronomy observations, and successfully demonstrated a high-performance cooled amplifier with power consumption three orders of magnitude lower than that of conventional cooled semiconductor amplifiers. This result is expected to contribute to the realization of large-scale multi-element radio cameras and error-tolerant quantum computers, both of which require a large number of low-noise microwave amplifiers.

The development of new information and communication technologies poses new challenges to scientists and industry. Designing new quantum materials -- whose exceptional properties stem from quantum physics -- is the most promising way to meet these challenges. An international team has designed a material in which the dynamics of electrons can be controlled by curving the fabric of space in which they evolve. These properties are of interest for next-generation electronic devices, including the optoelectronics of the future.

Leading edge technology has uncovered secrets about a world-renowned fossil hoard that could offer vital clues about early life on Earth. Researchers who analyzed the 400 million-year-old cache, found in rural north-east Scotland, say their findings reveal better preservation of the fossils at a molecular level than was previously anticipated.

Researchers have shown how energy disappears in quantum turbulence, paving the way for a better understanding of turbulence in scales ranging from the microscopic to the planetary. The team's findings demonstrate a new understanding of how wave-like motion transfers energy from macroscopic to microscopic length scales, and their results confirm a theoretical prediction about how the energy is dissipated at small scales. In the future, an improved understanding of turbulence beginning on the quantum level could allow for improved engineering in domains where the flow and behavior of fluids and gases like water and air is a key question. Understanding that in classical fluids will help scientists do things like improve the aerodynamics of vehicles, predict the weather with better accuracy, or control water flow in pipes. There is a huge number of potential real-world uses for understanding macroscopic turbulence.

Geneticists have written new chapters in the reconstruction of pre-colonial Americas history after using DNA from the indigenous Ashaninka people from Amazonian Peru. They have discovered previously unexpected levels of genetic variation in this group and uncovered a strong hint that these people were involved in a South-to-North migration that led to the transition from an archaic to ceramic culture in the Caribbean islands.
