Every year, our planet encounters dust from comets and asteroids. These interplanetary dust particles pass through our atmosphere and give rise to shooting stars. Some of them reach the ground in the form of micrometeorites. An international program conducted for nearly 20 has determined that 5,200 tons per year of these micrometeorites reach the ground.

The long-awaited first results from the Muon g-2 experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory show fundamental particles called muons behaving in a way that is not predicted by scientists' best theory, the Standard Model of particle physics.

The first result from the Muon g-2 experiment points to the existence of undiscovered particles or forces. These findings could have major implications for future particle physics experiments and could lead to greater understanding of how the universe works.

Most materials go from being solids to liquids when they are heated. One rare counter-example is helium-3, which can solidify upon heating. This counterintuitive and exotic effect, known as the Pomeranchuk effect, may now have found its electronic analogue in a material known as magic-angle graphene, says a team of researchers from the Weizmann Institute of Science led by Prof. Shahal Ilani, in collaboration with Prof. Pablo Jarillo-Herrero's group at the Massachusetts Institute of Technology (MIT).

A new estimation of the strength of the magnetic field around the muon--a sub-atomic particle similar to, but heavier than, an electron--closes the gap between theory and experimental measurements, bringing it in line with the standard model that has guided particle physics for decades.

Research team from University of Science and Technology of China realized synthetic gauge fields in a single optomechanical resonator, shedding new light on study of photons and realization of topological protection.

For the study, researchers were able to isolate and measure the quantum state of a single electron (the qubit) in a silicon transistor manufactured using a 'CMOS' technology similar to that used to make chips in computer processors.

The ALPHA collaboration at CERN has succeeded in cooling down antihydrogen atoms - the simplest form of atomic antimatter - with laser light.
