Tetraphenylammonium, with all four hydrogens of ammonium (NH4+) replaced with benzene rings, has neither been discovered in nature nor chemically synthesized, calling into question whether it could exist. Here, we succeeded in synthesizing tetraphenylammonium for the first time, demonstrating its stable existence. The synthetic strategy used in this study, radical coupling, may be applicable to the synthesis of various related ammoniums with high structural novelty.

A Hong Kong Baptist University (HKBU) collaborative research study has revealed that certain gut microbial enzymes mediate the reactivation of triclosan (TCS) from its inactive glucuronide metabolite. TCS is an antimicrobial agent commonly used in a wide range of consumer products, and it is associated with the development of colitis.

Osaka City University* study suggests memories are formed through an integration across brain regions via burst activity in amygdala-prefrontal neuronal ensembles during memory acquisition, and then hippocampal-prefrontal synchrony during post-experience sleep. (Osaka City University has now changed its name as Osaka Metropolitan University)

Similar to a magnet that always has both south and north poles, a kind of special quasiparticles in condensed matter called “Weyl Fermions” always appear in pairs with opposite chirality. There had been no experimental report that unpaired Weyl points exist in condensed matter until recently, a City University of Hong Kong (CityU) physicist observed the first unpaired singular Weyl magnetic monopole in a specific kind of single crystalline solid.

We have developed a groundbreaking chemical reaction using an N-heterocyclic carbene catalyst that has a low environmental impact to cleave the bond between the benzene ring of an aryl halide and a halogen atom to generate an aryl radical. Since aryl radicals can thus be easily generated from aryl halides that are widely used in organic synthesis, this is expected to be a powerful technology for precisely synthesizing medical and agricultural drugs and chemical materials.

Triple-negative breast cancer (TNBC) is an aggressive type of breast cancer with a high fatality rate. Currently, chemotherapy is the major treatment option, but the clinical result is unsatisfactory. A research team led by biologists at City University of Hong Kong (CityU) has identified and characterised a set of specific super-enhancers that stimulate the activity of the related critical cancer genes. The research has also discovered that the deletion of certain specific super-enhancers could reduce tumour cell growth. The latest findings may help discover new effective drug targets for TNBC patients to improve their survival chance.

Through a series of prosocial choice tasks, researchers reveal prosocial and antisocial characteristics in male convict cichlid fish. The fish distinguish between female breeding partners, unknown females, and rival males by adjusting their actions to either provide food for both them and the females or avoid providing food for the rival males.
