HKU Stephen Hui Geological Museum holds exhibition on private mineral collections in Hong Kong

The HKU Stephen Hui Geological Museum will hold in collaboration with the Mineralogy Society of Hong Kong a "Mineral Collections in Hong Kong" exhibition from March 3 to August 31, to showcase over 200 precious minerals from 18 private collectors in Hong Kong. The exhibits include one of the best gemmy single crystals of Tanzanite from Merelani Mine, a very rare large gem quality Aquamarine on Albite with large fluid inclusions from Balochi, Gilgit-Baltistan, Pakistan, and a 18 cm large gemmy Rhodochrosite on Quartz from the famous Sweet Home Mine in Colorado, U.S.A.. The mineral display cabinet of the late Dr Stephen Hui Sze-fun with a selection from his private collection is also included.

HKU conducted the first demographic study of the Chinese white dolphins in the Pearl River Estuary and urges conservation of dolphin critical habitat

A demographic study of the Chinese white dolphins inhabiting the Pearl River Estuary, led by Dr Leszek Karczmarski, Associate Professor at the HKU School of Biological Sciences, revealed that the PRE dolphin population is declining approximately 2.5% per year and is fast approaching its viability threshold. The findings indicated that the PRE dolphin population is deemed to become extinct unless effective conservation measures can rapidly reverse the current population trend.

HKU study reveals Hong Kong hosts more than ¼ of all marine species recorded in China

Hong Kong has a record of 5,943 marine species, according to a recent review by a research group led by Professor Gray A. Williams of The Swire Institute of Marine Science (SWIMS) and School of Biological Sciences of HKU. This first comprehensive review of local marine biodiversity shows that with only about 1,651 km2 marine area (~0.03% of China's total), Hong Kong already accounts for ~26% of the total marine species recorded in China. However, currently only less than 2% of Hong Kong’s marine area is protected as marine parks or reserve. The research team urged the government to move towards the global target of at least 10% marine protected area by the year 2020 under United Nation's Convention on Biological Diversity (CBD). To establish a platform for the international scientific community to access the marine species in Hong Kong for conservation, research and education purposes, the research team, in collaboration with international experts, has also launched the Hong Kong Register of Marine Species (HKRMS) under the umbrella of the largest global marine biodiversity database, the World Register of Marine Species (WoRMS). Hong Kong is one of only ten regions in the world that has such a regional species database, and was the first in Asia.

International study reveals 82% of core ecological processes compromised by climate change

An international study led by University of Florida, with participation from the HKU School of Biological Science, revealed that 82% of the 94 identified ecological processes have been compromised by climate change. Land, freshwater and marine ecosystems and species have all been all affected, and consequential impacts on people could range from increased pests and disease outbreaks, to unpredictable changes in fisheries and decreasing agriculture yields. Co-author Professor David Dudgeon, Director of the School of Biological Sciences, warned that local species like paradise fish, short-legged toad and Hong Kong newt are at risk as habitats shrink. The research team hopes the research could steer governments in the right direction and deliver the message that climate change is not just a projection and that the effects on ecological processes are already happening. The study was published in the prestigious journal Science.

Knowledge Exchange Awards 2016

The annual Faculty Knowledge Exchange (KE) Awards recognize each Faculty's outstanding KE accomplishment that has made demonstrable economic, social or cultural impacts to benefit the community, business/industry, or partner organizations. The KE Award (Non-Faculty Unit) was introduced with the same objective for the independent centres, institutes and units of the University. Results of the 2016 KE Awards are now available.

HKU chemists achieve breakthrough in antibacterial drug development

Dr Li Xuechen of the HKU Department of Chemistry and his research team, together with collaborators in the University of Central Florida and PolyU, reported in Nature Communications their studies on the synthesis of a newly discovered antibiotic Teixobactin, which can kill a range of pathogens without detectable resistance. The discovery underlies potential application and development of the next-generation teixobactin-based antibacterial drugs. The team was one of the fastest groups in the world to complete the chemical synthesis of teixobactin, from which they have also generated 10 teixobactin analogues with US provisional patent filed.

New ant species Paratopula bauhinia (Golden Tree Ant) described and named by HKU biologists

The Insect Biodiversity and Biogeography research group led by Dr Benoit Guénard at the HKU School of Biological Sciences has described and named a new species of ant from Hong Kong, Paratopula bauhinia, or the rare "Golden Tree Ant", in academic journal "Asian Myrmecology". This new ant species was found just a few hundred meters from HKU campus on the foothill of Lung Fu Shan Country Park during a night field course by Ms Ying Luo, a research assistant with the School of Biological Sciences. The ant is about 7mm long and golden in appearance. The new ant represents the 22nd ant species described from Hong Kong since 1858. The last one was in 2000. Descriptions of earlier species had to be dated back to 1928.
