Researchers have discovered a new, innermost layer nestled inside our planet’s inner core, a 400-miles solid metallic ball that responds to the reverberating shockwaves of earthquakes in an unexpected way.

As detailed in a new paper published this week in the journal Nature Communications, a team of two seismologists from the Australian National University found that the Earth has an “innermost inner core,” which may have been formed following a “significant global event from the past.”

“Clearly, the innermost inner core has something different from the outer layer,” lead author Thanh-Son Pham, a seismologist at the Australian National University, told The Washington Post. “We think that the way the atoms are [packed] in these two regions are slightly different.”

It hasn’t existed since the beginning of time itself, but now scientists have managed to create what they call quark soup. This substance is believed to be the smallest, hottest, and densest state of our universe and the very “soup” that allowed the universe to grow and expand into what we know it as today.

The feat was made possible thanks to a powerful yet very complicated particle accelerator. According to research featured in a video by Scientific American, the universe began as a quark soup — the smallest, most fundamental building blocks of our atoms. Scientists say these quarks floated in a fluid-like force that held them all together inside their proton and neutrons.

An unusual form of cesium atom is helping a University of Queensland-led research team unmask unknown particles that make up the universe.

Dr. Jacinda Ginges, from UQ’s School of Mathematics and Physics, said the unusual atom—made up of an ordinary cesium atom and an elementary particle called a muon—may prove essential in better understanding the universe’s fundamental building blocks.

“Our universe is still such a mystery to us,” Dr. Ginges said.

Several studies have predicted that the water splitting reaction could be catalyzed by certain groups of 2D materials—each measuring just a few atoms thick. One particularly promising group are named 2D Janus materials, whose two sides each feature a different molecular composition.

Through new calculations detailed in The European Physical Journal B, Junfeng Ren and colleagues at Shandong Normal University in China present a new group of four 2D Janus materials, which could be especially well suited to the task.

Since hydrogen releases an abundance of energy when combusted, with only water as a byproduct, it is now widely seen as an excellent alternative to fossil fuels. Splitting water molecules involves a redox reaction, where electrons and holes participate in reduction and oxidation reactions.

No one has ever probed a particle more stringently than this.

In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise measurement of any property of an elementary particle, ever. Known as the electron magnetic moment, it’s a measure of the strength of the magnetic field carried by the particle.

That property is predicted by the standard model of particle physics, the theory that describes particles and forces on a subatomic level. In fact, it’s the most precise prediction made by that theory.

Superconductivity can be switched on and off in “magic-angle” graphene using a short electrical pulse, according to new work by researchers at Massachusetts Institute of Technology (MIT). Until now, such switching could only be achieved by sweeping a continuous electric field across the material. The new finding could help in the development of novel superconducting electronics such as memory elements for use in two-dimensional (2D) materials-based circuits.

Graphene is a 2D crystal of carbon atoms arranged in a honeycomb pattern. Even on its own, this so-called “wonder material” boasts many exceptional properties, including high electrical conductivity as charge carriers (electrons and holes) zoom through the carbon lattice at very high speeds.

In 2018, researchers led by Pablo Jarillo-Herrero of MIT found that when two such sheets are placed on top of each other with a small angle misalignment, things become even more fascinating. In this twisted bilayer configuration, the sheets form a structure known as a moiré superlattice, and when the twist angle between them reaches the (theoretically predicted) “magic angle” of 1.08°, the material begins to show properties such as superconductivity at low temperatures – that is, it conducts electricity without any resistance.

Researchers at Harvard University, the Lawrence Berkeley National Laboratory, Arizona State University, and other institutes in the United States have recently observed an antiferromagnetic metal phase in electron-doped NdNiO₃ a material known to be a non-collinear antiferromagnet (i.e., exhibiting an onset of antiferromagnetic ordering that is concomitant with a transition into an insulating state).

“Previous works on the rare-earth nickelates (RNiO₃) have found them to host a rather exotic phase of magnetism known as a ‘noncollinear antiferromagnet,’” Qi Song, Spencer Doyle, Luca Moreschini and Julia A. Mundy, Four of the researchers who carried out the study, told Phys.org.

“This type of magnet has unique potential applications in the field of spintronics, yet rare-earth nickelates famously change spontaneously from being metallic to insulating at the exact same temperature that this noncollinear antiferromagnet phase turns on. We wanted to see if we could somehow modify one of these materials in a way so that it remained metallic, but still had this interesting magnetic phase.”

Arctic and save Greenland’s glaciers.

George Soros proposes geoengineering project to save Greenland’s glaciers.

Less problematic geoengineering already is underway with CO₂ direct air capture. But more controversial sunlight blocking is being proposed.

Two groups demonstrate innovative ways to capture the ultrafast motion of electrons in atoms and molecules.

Electrons move so quickly inside of atoms and molecules that they are challenging to “capture on film” without blurring the images. One way to take fast snapshots is to ionize an atom or molecule and then use the released electrons as probes of the cloud out of which they originate. Now Gabriel Stewart at Wayne State University in Michigan and colleagues [1] and Antoine Camper at the University of Oslo in Norway and colleagues [2] have improved this “self-probing” technique. The demonstrations could lead to a better understanding of the electron motion that underpins many fundamental processes.

Scientists need to complete three key tasks to measure the evolution of an electron cloud that moves and changes on an ultrafast timescale. The first is to exactly record the beginning of the evolution—analogous to pressing “start” on a mechanical stopwatch. The second is to track how much time has gone by since the starting event—analogous to precisely measuring the ticking of the stopwatch’s second hand. And the third is to take a quick snapshot of the electron cloud so that it looks frozen in time.
