Carbon dioxide (CO2) is one of the major greenhouse gases causing global warming. If the carbon dioxide could be converted into energy, it would be killing two birds with one stone in addressing the environmental issues. A joint research team led by City University of Hong Kong (CityU) has developed a new photocatalyst which can produce methane fuel (CH4) selectively and effectively from carbon dioxide using sunlight. According to their research, the quantity of methane produced was almost doubled in the first 8 hours of the reaction process.

Native bittering fish, Tanakia lanceolata
04 Jan 2021
Reproduction of native and invasive bitterling fishes and their hybridisation was studied in Japan. We collected mussels in which these bitterlings lay their eggs, kept them in aquaria, collected eggs/larvae ejected from mussels, and genotyped them. We found that hybrids occurred when local mussel density was low. The rapid decline of the host mussels and artificial introduction of an invasive congener interacted to cause the rapid decline of a native fish.
Relationship between OHC levels and transcriptome profiles in salmon collected from three areas of the Baltic Sea
16 Dec 2020
Researchers of Ehime University and the University of Helsinki measured hepatic organohalogen (OHC) concentrations and gene expression profiles in Atlantic salmon collected from three areas in the Baltic Sea. The results showed that OHCs and gene expression profiles were individually grouped in three areas and the covariation of the two datasets provided by a multivariate method was significantly similar. This suggests that the gene expression profiles in salmon are affected by OHC contamination.

Image for sedimentary DNA analysis
10 Nov 2020
Far too little is known about the long-term dynamics of the abundance of most macro-organism species. We used sedimentary DNA technology to quantify marine fish DNA abundance in sediment sequences spanning the last 300 years. This study first shows the existence of fish DNA in the sequences and proves that fish abundance can be tracked using sedimentary DNA, highlighting the utility of sedimentary DNA for researchers to acquire lengthy records of macro-organism species abundance.
Eco-engineered tiles
06 Nov 2020
A joint-study led by a team of marine ecologists from City University of Hong Kong (CityU) has found that the eco-engineered tiles can increase habitat complexity on seawalls in Hong Kong, thereby effectively enhancing the marine biodiversity. The Hong Kong study is part of a global research project on the relationship between habitat complexity and marine biodiversity on human-built marine structures.

Governments around the world are taking steps to slow the pace of global warming. In the report titled "Hong Kong’s Climate Action Plan 2030+", a 70 per cent reduction in carbon intensity by the year 2030 was set. Achieving this ambitious target will require a major change in behaviour at both the corporate and individual levels.

Nestled at the base of a scenic mountain range in the northeast part of Hong Kong, the campus of The Education University of Hong Kong (EdUHK) is rich in biodiversity. Members of the University community recorded over 1,270 observations of 380 species of trees, plants, insects, birds, fungi and reptiles in the worldwide City Nature Challenge 2019.

The COVID-19 outbreak is causing widespread disruption to daily life. Hong Kong people living in cramped subdivided flats with poor hygiene conditions have been particularly hard hit. In light of this alarming situation, Lingnan University (LU) jointly launched “Project Ultra Violite” with NGOs to provide a free, efficient UV disinfection service for 1,000 subdivided flats. It is the territory’s first community-wide programme using UV disinfection technology.

Three developing stages and OH-PCBs concentration of a Japanese macaque fetus
14 Sep 2020
This study selected the Japanese macaque (Macaca fuscata) as a model animal for the fetal transfer of OH-PCBs in humans, and revealed OH-PCB concentrations and their relationships in the maternal and fetal brains. The key finding from this study is that OH-PCBs can reach the developing brain of the fetus as early as the first trimester of pregnancy. These OH-PCBs may exceed the levels that induce adverse effects on neurodevelopment.

Researchers from the Earth System Science Programme at The Chinese University of Hong Kong (CUHK) have revealed that slow earthquakes, a new type of earthquake discovered about 20 years ago, follow similar scaling relations as regular earthquakes, e.g. rate of aftershocks and formula that relates an earthquake’s energy release with how long it lasts. This discovery opens a pathway for scientists to use these events as easy-to-study analogs to probe the physics governing the power and timing of devastating earthquakes, generating a clearer picture of how energy is released with time along faults.

Giants in history

Tetsuya Theodore Fujita (23 October 1920 – 19 November 1998) was a Japanese-American meteorologist who created the Fujita scale that classifies the strength of tornadoes based on damage to structures and vegetation.
Archana Sharma (16 February 1932 - 14 January 2008) conducted research into plant and human genetics that expanded the understanding of both botany and human health. In relation to botany, she uncovered the means by which asexually-reproducing plants evolve into new species.
Roseli Ocampo-Friedmann (23 November 1937 – 4 September 2005) was a Filipino-American scientist whose research focused on cyanobacteria and microorganisms that inhabit extreme environments.
Edgardo Dizon Gomez (7 November 1938 – 1 December 2019) was a Filipino marine biologist who recognized the need to protect marine resources, especially coral reefs, in the Philippines.
Anna Mani (23 August 1918 – 16 August 2001) was an Indian meteorologist who contributed significantly to the understanding of solar radiation, ozone and wind energy by developing a wide range of measurement tools. One of India’s pioneering female scientists, Mani excelled in the male-dominated area of meteorology and became the Deputy Director-General of the India Meteorological Department.
Võ Quý (1929 – 2017) was a Vietnamese ornithologist who studied the destruction of tropical forests and agricultural lands in Vietnam by Agent Orange, a herbicide used by the U.S. military during the Vietnam War. In addition to planning forest restoration projects, Quý rediscovered the rare eastern sarus crane, an endangered species that had vanished during the war.
