HKU physics Ph.D. student obtained the Higgs mode via dimensional crossover in quantum magnets revealing importance of dimensions in many-body systems

By combining numerical and analytic analyses, the research team successfully explained revealed the clear presence of the Higgs mode in the quasi-1D quantum magnetic systems. The results not only can help to find out the key model parameters of the material but also reveal a picture of how dimension matters in the condensed material. These research finding has been published in one of the most...

HKU scientists reveal silver-based antimicrobials can be utilized as antibiotic adjuvants to combat antibiotic-resistant Staphylococcus aureus

A research team at the University of Hong Kong discovers that silver (Ag)-based antimicrobials can effectively combat antibiotic resistant Staphylococcus aureus by targeting multiple biological pathways via functional disruption of key proteins and can be further exploited to enhance the efficacy of conventional antibiotics as well as to resensitize methicillin-resistant Staphylococcus aureus...

New technique allows for identification of potential drugs to fight resistant bacteria

Researchers from the Miami University in Ohio have optimized a new technique that will allow scientists to evaluate how potential inhibitors work on antibiotic-resistant bacteria. This technique, called native state mass spectrometry, provides a quick way for scientists to identify the best candidates for effective clinical drugs, particularly in cases where bacteria can no longer be treated with...

Pathogenic bacteria rendered almost harmless

Pseudomonas aeruginosa can cause chronic infections that are potentially fatal for people with weakened immune systems. In addition, its adaptability and resistance to many antibiotics make infections by P. aeruginosa increasingly difficult to treat. There is therefore an urgent need to develop new antibacterials. Scientists (UNIGE) have identified a previously unknown regulator of gene expression...
