Research on the historical grading of World War II Allied and Japanese military pillboxes in the new territories as Hong Kong’s educational and tourism assets

Researchers mapped accessible routes to 59 surviving pillboxes along the Gin Drinker's Line in the New Territories, providing guides for visiting British and Japanese military sites. The study highlights the importance of these structures as a unique part of Hong Kong's WWII history and potential tourism assets.

HKU researchers discover new tectonic regime of terrestrial planets, offering new insights into the evolution of Earth and Venus

Researchers from HKU identified six distinct tectonic regimes on terrestrial planets, including a novel 'Episodic-Squishy Lid' regime. This discovery provides clues to the origin of Earth's plate tectonics and offers a robust theoretical framework for deciphering Venus' enigmatic geological features.

Lower doses of immunotherapy for skin cancer give better results

A new study by researchers at Karolinska Institutet found that lower doses of approved immunotherapy drugs can give better results against tumours, while reducing side effects. The regimen with the lower dose of ipilimumab was more effective, with a higher proportion of patients responding to treatment and longer overall survival.

Why didn’t the senior citizen cross the road? Slower crossings may help people with reduced mobility

Research finds that standard road crossing intervals are too short for older adults with limited mobility, resulting in a need for slower crossings. The study analyzed walking speeds of 1,110 adults aged 65 and over and found that just 1.5% can cross the road within the typical time allowed by pedestrian signals.

ASH 2025: Study suggests that a virtual program focusing on diet and exercise can help reduce side effects of lymphoma treatment

A new study presented at ASH 2025 suggests that a virtual program focusing on diet and exercise can help reduce the severity of side effects associated with lymphoma treatment. The program, LIFE-L, showed significant improvements in symptoms such as anxiety, depression, pain, fatigue, and constipation among participants.

A sound defense: Noisy pupae puff away potential predators

In a study published in the Journal of Experimental Biology, researchers from Kobe University found that hawkmoth larvae and pupae produce defensive sounds when stimulated. These sounds are released through respiratory openings and resemble snake warning signals, potentially helping the insects evade predators.
