SECRETS OF ASTEROID RYUGU

Ryugu’s interaction with the sun changes what we know about asteroid history. In February and July of 2019, the Hayabusa2 spacecraft briefly touched down on the surface of near-Earth asteroid Ryugu. The readings it took with various instruments at those times have given researchers insight into the physical and chemical properties of the 1-kilometer-wide asteroid. These findings could help expla

LASER LIGHT ACTS AS A MECHANICAL SPRING IN QUANTUM WORLD

Quantum technology is currently one of the most active fields of research worldwide. It takes advantage of the special properties of quantum mechanical states of atoms, light, or nanostructures to develop, for example, novel sensors for medicine and navigation, networks for information processing and powerful simulators for materials sciences. Generating these quantum states normally requires a strong interaction between the

WHAT IS FRACKING? FACTS ABOUT FRACKING

Hydraulic fracturing, Also Known As Fracking, is a Well stimulation technique in which rock is fractured by a pressurized liquid. The process involves the high-pressure injection of ‘fracking fluid’ (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures op

A NEW REPORT FINDS RENEWABLE POWER SOURCES HAVE MADE GAINS AS FOSSIL FUEL USE HAS DECLINED DURING THE PANDEMIC

The precipitous drop in energy use is unparalleled back to the Great Depression of the 1930s. But not all energy sources are suffering equally. Efforts to shift toward renewable energy could be hastened, as fossil fuels, particularly coal and oil, have borne the brunt of the decline. Use of renewable energy meanwhile has risen, thanks to new projects coming online, and the low cost of turning wind turbines or harvesting sunlight.

USE OF QUANTUM ENTANGLEMENT TO DETECT RADIO FREQUENCIES WITH MORE SENSITIVITY AND ACCURACY THAN EVER, BUT HOW?

In a new paper published in Physical Review Letters, University of Arizona engineering and optical sciences researchers, in collaboration with engineers from General Dynamics Mission Systems, demonstrate how a combination of two techniques (radio frequency photonics sensing and quantum metrology) can give sensor networks a previously unheard-of level of precision.

MIRROR-SYMMETRY VIOLATION IN BOUND NUCLEAR GROUND STATES

The breakthrough by the researchers revealed that a symmetry that exists within the core of atoms is not as fundamental as scientists have believed. The discovery sheds light on the forces at work within the nucleus of atoms, opening the door to a greater understanding of the universe.
