Living beings need elements to develop properly. The study of ionomics measures and analyses the element accumulations in living organisms to determine which mineral nutrients are required and not required for growth. Associate Professor Toshihiro Watanabe from Hokkaido University’s Research Faculty of Agriculture applies this approach to learn about mineral accumulation in both plants and soil, in addition to inter-element interactions.

A hydrogel, a type of soft matter, developed at Hokkaido University successfully reverted cancer cells back to cancer stem cells within 24 hours, in six different human cancer types. This could lead to the development of anti-cancer stem cell drugs and personalized medicines.
Figure 1: The drawing shows a clam with its foot extending deep into the sediment to gain access to hydrogen sulfide. The foot and mantle of the clam are red due to the presence of haemoglobin for gas transport in the blood, which is an adaptation to the low-oxygen environment. (Drawn by HKBU student Hu Juntong)

A study led by scientists at Hong Kong Baptist University (HKBU) has decoded the genomes of the deep-sea clam (Archivesica marissinica) and the chemoautotrophic bacteria (Candidatus Vesicomyosocius marissinica) that live in its gill epithelium cells. Through analysis of their genomic structures and profiling of their gene expression patterns, the research team revealed that symbiosis between the two partners enables the clams to thrive in extreme deep-sea environments.

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.

New research from Duke-NUS Medical School, and the Agency for Science, Technology and Research identifies chemotherapy-resistant cancers’ escape mechanism, which offers new anti-cancer treatment options.
14 Mar 2021
The Science Unit of Lingnan University (LU) in Hong Kong has reported a novel form of reproductive behaviour observed in a native frog species, Lau’s Leaf Litter Toad (Leptobrachella laui). Unconventionally, the female frog positions herself on top of the male, which is a reverse of the more usual mating arrangement.

Scientists have discovered a route of introduction for High Pathogenicity Avian Influenza Virus (HPAIV) H5N8 into Japan and, in parallel, have investigated the potential of two human anti-influenza drugs for the control of HPAI in birds.

Researchers reveal the path of information received by the hippocampus. Using optogenetics during large-scale recordings of rat subiculum, they discovered that the subiculum distributes information from the hippocampus to 4 downstream regions of the brain. They observed that the theta and sharp-wave/ripples in the subiculum controlled information transmission with millisecond precision according to the target region. This provides the foundation for a comprehensive understanding of the hippocampal memory system.

Osaka City University finds that the chemical sesaminol, naturally occurring in sesame seeds, protects against Parkinson’s disease by preventing neuronal damage that decreases the production of dopamine. In vitro experiments show sesaminol handle oxidative stress in cells by regulating the production of reactive oxygen species and the movement of antioxidants. In vivo experiments reveal that a diet of sesaminol increases production of dopamine and significantly improve motor functions in mice.

Spinocerebellar ataxia type 3 (SCA3), also known as Machado-Joseph Disease (MJD), describes the most common form of dominantly inherited ataxia in many populations worldwide, including Hong Kong and mainland China. SCA3 or MJD patients often present problems with gait and balance, blurred vision, and speech difficulties. The symptoms are progressive, and patients may eventually decline into a bed-ridden state. To date, SCA3 or MJD remains an incurable disorder. Collaborating with the University of Oxford, Professor Ho Yin Edwin Chan’s research team from the School of Life Sciences of The Chinese University of Hong Kong (CUHK) recently unveiled the counteracting relationship between pre-mRNA-processing factor 19 (Prpf19) and exocyst complex component 7 (Exoc7) in controlling the degradation of disease protein and neurodegeneration of the rare hereditary ataxia. The research findings have been published in the prestigious scientific journal, Cell Death & Disease.

Cylindrotomid cranefly larva uncannily resembling mosses
25 Feb 2021
The roles of physical structures in animal camouflage are not well known. This study illuminates an overlooked role of a mechanism for camouflage. Dr. Imada investigated how larvae of the long-bodied crane flies achieve uncanny resemblance to mosses, highlighting the functions of their special body armature, "fleshy lobes". The lobes on the lateral sides of the body had internal muscles, suggesting that they are not only for tricking enemy's eyes, but may also aid the larvae in crawling.
