Today, many research teams worldwide are trying to detect dark matter, an invisible substance that is believed to account for most of the matter in the universe. As does not reflect or emit light, its presence has been indirectly revealed via its gravitational...

The IceCube Collaboration sets the most restrictive constraints on relic magnetic monopoles from the early universe
Recent technological advances have enabled the development of increasingly advanced telescope and astrophysical instruments. This includes the IceCube telescope, which was originally built to detect and examine high-energy neutrinos in the universe.
Examining the results of new dark matter searches by the PandaX-4T and ADMX collaborations
Physicists have predicted the existence of dark matter, a material that does not absorb, emit or reflect light, for decades. While there is now significant evidence hinting to the existence of dark matter in the universe, as it was never directed detected before its...
Theory shows baryogenesis requirement could drive the contribution of primordial black holes to dark matter
While many studies have hinted at the existence of dark matter, a material that does not absorb, reflect or emit light, this elusive substance has not been directly observed so far. Over the past few decades, many teams worldwide have thus theorized about its possible...
Study introduces the intrinsic superconducting diode effect
In 2020, Prof. Teruo Ono and his colleagues at Kyoto University reported the very first observation of a magnetically controllable, superconducting diode effect in an artificial superlattice. Their findings, published in Nature, paved the way for other studies...
A new paradigm to break the electromagnetic reciprocity in 3D bulk metamaterials
Transistors based on semiconductor materials are widely used electronic components with many remarkable properties. For instance, they have a nonreciprocal electrical response, which means that they can isolate two parts of a circuit in such a way that one of the...
Dark matter travelling through stars could produce potentially detectable shock waves
Dark matter, a hypothetical material that does not absorb, emit or reflect light, is thought to account for over 80 percent of the matter in the universe. While many studies have indirectly hinted at its existence, so far, physicists have been unable to directly...
Study finds that black hole inner horizons can be charged or discharged
Black holes are intriguing and widely studied cosmic bodies with extremely high tidal forces, from which even light is unable to escape. While many studies predicted the existence of black holes, which have also recently been detected, many questions about these...
Information processing constrains how E. coli bacteria navigate chemical gradients
Living organisms adapt their behavior and movements based on information they acquire from their surrounding environment. But oftentimes this information is imperfect, and the organism needs to act under uncertainty. So, does imperfect information limit an organism's...
Evidence of a quantum phase transition without symmetry breaking in cerium-cobalt-indium 5
Over the past few decades, many condensed matter physicists have conducted research focusing on quantum phase transitions that are not clearly associated with a broken symmetry. One reason that these transitions are interesting is that they might underpin the...
