Scientists from HKUST and Harvard-Smithsonian Center for Astrophysics discovered a method to observationally distinguish different theories of how the universe first began at its very early stage. The findings were accepted by the Journal of Cosmology and Astroparticle Physics. The expansion of our current universe has been established for almost a century. However, concerning much earlier stages of our universe as how it began has always been a topic of contention among scientists. The most widely-accepted theory of the primordial universe is cosmic inflation, during which the universe was expanding at an extremely fast and mounting rate. On the other hand, there are also contending theories which believe that our infant stage universe was fast contracting, slowly contracting, static or slowly expanding.

Theoretical physicists from the Department of Physics at the Hong Kong University of Science and Technology (HKUST) gave an explanation to the phenomenon of superconductivity surviving under strong magnetic field, offering a theoretical answer to an unsolved experimental observation by a group of scientists in the Netherlands. The collective findings were published on November 12, 2015 in Science. [DOI:10.1126/science.aab2277].(http://m.sciencemag.org/content/early/2015/11/11/science.aab2277.abstract) Superconductivity is a quantum phenomenon in which electrons form pairs and flow with zero resistance. However, strong enough magnetic field can break electron pairs and destroy superconductivity.  When researchers from the Netherlands informed Prof Vic Law’s team that superconductivity in thin films of MoS2 could withstand an applied magnetic field as strong as 37 Tesla, Prof Law and his student Noah Yuan came up with an explanation.

A team formed by HKUST biomaterial researchers develops the world’s first injectable hydrogel formulation that allows a long, sustainable release of protein therapeutics which can be used to treat eye diseases like macular degeneration and diabetic retinopathy. Nowadays, patients with these diseases have to be treated by monthly injection for years, which is far from an ideal treatment regime. Team member Yu Yu, a postdoctoral fellow in Biomedical Engineering at HKUST, said: “Drugs formulated with our novel hydrogel material could be injectable as usual but release slowly from the depot, potentially providing effective long lasting treatment on patients.” The hydrogel formulation is set to be injected only once per year, sparing patients from having to endure monthly injections. This helps cut down medical expenses and lower the risk associated with repeated injections, Prof. Ying Chau, Associate Professor form Biomedical Engineering at HKUST added.

A research team led by Prof Vic Kam Tuen Law, Assistant Professor of the Department of Physics at the Hong Kong University of Science and Technology (HKUST), gave an explanation to the complex phenomenon of superconductivity that survives under strong magnetic field, offering a theoretical answer to an unsolved experimental observation by a group of scientists in the Netherlands. The collective findings were published in Science on 12 November 2015. Superconductivity is a quantum phenomenon in which electrons form pairs and flow with zero resistance. However, strong enough magnetic field can break electron pairs and destroy superconductivity. When informed by researchers from the Netherlands that superconductivity in thin films of MoS2 could withstand an applied magnetic field as strong as 37 Tesla, Prof Law and his student Mr Noah Yuan came up with an explanation and solved the puzzle.

What would happen to our lives if robots could read our emotions and act like a friend?  It may sound like some plots in science fiction movies, but Prof Pascale Fung from the Department of Electronic and Computer Engineering at the Hong Kong University of Science and Technology (HKUST) has realized this dream.  An expert in intelligent systems that understand and empathize with humans, Prof Fung’s latest project “Zara the Supergirl” is a prototype machine capable of chatting with humans in both English and Mandarin, it is expected to chat in more languages including French in the future.

HKUST researchers recently found a way to stimulate the growth of axons, which may mark a new beginning on chronic spinal cord injury (SCI) treatments. SCI is a formidable hurdle that prevents a large number of injured axons from crossing the lesion, particularly the corticospinal tract (CST). Patients inflicted with SCI often suffer a loss of mobility, paralysis, and interferes with activities of daily life dramatically. Led by Professor Kai Liu, Assistant Professor from Department of Life Sciences at HKUST, the HKUST research team initiated PTEN deletion on mice after pyramidotomy. Similar treatment procedures were carried out 4 months and 12 months after severe spinal cord injuries. The team recorded a regenerative response of CST axons in all three samples – showing that PTEN deletion stimulates CST sprouting and regeneration, even though the injury was sustained a long time ago.

A team of scientists from the Division of Life Science and HKUST Jockey Club Institute for Advanced Study at the Hong Kong University of Science & Technology, and School of Life Sciences at Tsinghua University are the first to solve the near atomic structure of the MCM2-7 Complex, which plays a key role in destabilizing and unwinding duplex DNA during DNA replication. The work is published in an article in the journal Nature on July 29, 2015 (http://dx.doi.org/10.1038/nature14685) and highlighted in a commentary in News and Views in the same issue (http://www.nature.com/nature).
