Led by researchers from the Institute of Physics at Princeton University, an initial discovery has been published that strengthens the controversial hypothesis that the electron is made up of two elementary particles: one carries a negative electric charge and the other the electron's spin. If the interpretation is indeed correct, the assumption that is more than a century old may be erased and make waves in the scientific community.

Last Tuesday, the Premilab laboratories in the United States announced that the muon's magnetic moment does not match the theoretical calculations. The experiment conducted in the state of Illinois confirms the anomaly that was discovered several years ago. Is this evidence of a new fundamental force in nature?

After almost two decades accompanied by technical and financial challenges, on the XNUMXth of April we heard, perhaps, exciting news from Permilab Laboratories in the United States. The experiment run for the second time was set up to measure the muon's magnetic moment and if a deviation is detected, even the smallest, it may hint at a new elementary particle in nature

A new record in the measurement of the gravitational field was broken in a study recently published in the prestigious magazine Nature. Measuring gravity on a microscopic scale, which is significantly weaker than the other forces in nature, is a huge technological and scientific challenge. However, gravitational experiments at the atomic scale are critical to understanding the quantum nature of gravity. In the future, will we be able to stretch the limits of the experiment to single micrograms?

The European Organization for Nuclear Research (CERN) has announced that the Large Hadron Collider has discovered four new particles, but what has changed? Since the accelerator was first activated in 2009, 59 new particles have been discovered, including the famous Higgs boson that was discovered in 2012. Although most of the new particles were discovered in accordance with expectations, some of them were particularly surprising

In a joint study by researchers from Germany and Poland, a time crystal in action was filmed for the first time. The micrometer crystal consists of mechanisms at room temperature. Using X-rays, the researchers from Berlin recorded the magnetization of the crystal over time and recorded its cyclic behavior

This research, recently carried out by Prof. Jay Feinberg and Neri Berman from the Rekh Institute of Physics, was published in the prestigious journal Physical Review Letters. The study revealed, for the first time, the behavior in the immediate vicinity of the crack tip. In fact, this is the first time in the world that this tiny region, where material breaking occurs, has been observed in a laboratory experiment

Researchers around the world are looking for an explanation for the mystery of dark matter and the problem of hierarchy. The two problems seem completely different, but according to researchers from Johns Gutenberg University in Germany, both can be solved with the help of a compact fifth dimension. The estimated model does not contradict the experimental data discovered in current accelerators and predicts a new particle with a mass of 30TeV that may be discovered in future accelerators

Many people feel that their experience of time has been a bit problematic this year. Although the clocks are ticking as they should, days stretch and months seem to drag on forever. We all know there are 60 seconds in a minute but 2020 has made us all aware of how we can experience the passage of time a little differently
