A research team from the Department of Medicine, School of Clinical Medicine, LKS Faculty of Medicine at the University of Hong Kong (HKUMed) has uncovered a key biological mechanism that explains how exercise maintain strong bones, paving the way for novel treatments for osteoporosis and bone loss in people who are unable to engage. By identifying a protein that acts as the body’s ‘exercise sensor’, the research has opened the door to the development of drugs that mimic the effects of physical activity, offering hope for vulnerable groups, such as the elderly, bedridden patients and those with chronic illnesses who face a high risk of fractures. The research findings were published in the journal Signal Transduction and Targeted Therapy.

The University of Hong Kong (HKU) and Tsinghua University signed five Memoranda of Understanding (MoUs) on 22 December 2025, expanding their partnership across diverse fields including public health, engineering, law, and astronomy, further strengthening the partnership between the two institutions in academic research and talent development.

Flu activity has surged in many parts of the Northern Hemisphere, driven primarily by a newly emerged H3N2 strain known as ‘subclade K’. A research team led by the Department of Microbiology and the Department of Medicine, both under the School of Clinical Medicine at the LKS Faculty of Medicine of the University of Hong Kong (HKUMed), has found that most hospital patients in Hong Kong have little to undetectable levels of neutralising antibodies against this mutated strain. HKUMed researchers strongly advise the public to get vaccinated as soon as possible.

An innovative teaching project led by Mr Ki Sum Samson Wong, Assistant Lecturer in the Medical Ethics and Humanities Unit of the School of Clinical Medicine, LKS Faculty of Medicine at The University of Hong Kong (HKU), has recently won a Gold Award in the Nurturing Wellbeing and Purpose category at QS (Quacquarelli Symonds) Reimagine Education Awards 2025. Mr Wong’s teaching initiative was the only Hong Kong-based entry to receive a Gold-level Award at this year’s QS Reimagine Education Awards and Conference held in London on December 1-3, 2025.

A study published in the Journal of Nutritional Physiology suggests that muscle impairment persists even after weight recovery from anorexia nervosa.

When some women orgasm, they experience unusual physical and emotional responses such as laughing, crying, headaches, tingling, foot pain, nosebleeds and more. Known as peri-orgasmic phenomena, the responses are not related to the normal physiology of an orgasm. 

A new survey-based Northwestern University study is the first to break down how frequently and consistently women experience these responses, and when they’re more likely to occur (i.e. with a partner or during masturbation). 

While the study found these responses are rare — only 2.3% of the sample — the findings are necessary to raise awareness and help reassure women these responses are within the realm of a normal sexual response, the study authors said.
