When the clocks stop changing: What time is best for health?

Canadian Medical Association Journal
Peer-Reviewed Publication

Several Canadian jurisdictions are moving toward ending the twice-yearly clock change, but a new analysis published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.261089 argues that eliminating the clock change is only half the decision: governments must also decide whether to adopt permanent standard time or permanent daylight saving time. Both choices have trade-offs. Permanent daylight saving time keeps evenings lighter, which may support recreation, social activity, commuting, and some economic activity.

Regular walking is good for people with COPD, even if they live in areas with higher air pollution

European Respiratory Society
Peer-Reviewed Publication

Regular walking reduces symptom flare ups for people with chronic obstructive pulmonary disease, even if they live in an area with poor air quality, according to a study published in ERJ Open Research. Until now, doctors have been concerned about recommending walking if they know their patients live in areas with high levels of air pollution. The new research suggests walking is beneficial, regardless of air quality.

New global survey shines a light on the patients who rely on plasma-derived medicines—and the donors who make them possible

The Plasma Protein Therapeutics Association
Reports and Proceedings

An international survey of more than 1,100 patients, caregivers, healthcare providers and patient advocates found high confidence in plasma-derived medicines and deep gratitude for the donors who make them possible.

The Lancet: Scale of young people’s digital media use and emerging evidence of harm justify action now, experts argue

The Lancet
Peer-Reviewed Publication

The way digital technologies are currently built and governed creates real risks to health worldwide, alongside genuine benefits, according to a new three paper Series authored by 13 global experts, published in The Lancet. The authors call for coordinated governance of digital systems, with the health and online safety of children and young people made an immediate global policy priority.

Priorities for tackling global plastic pollution

Science China Press
Peer-Reviewed Publication

A paper published in National Science Review brings together evidence on how plastics are produced, released, transported and transformed, and how they affect ecosystems, human health and Earth-system processes. It argues that lasting solutions must address the full plastics life cycle, with upstream prevention and safer design supported by reuse, recycling, pollution control, monitoring, and coordinated global governance.

KRAS inhibition combined with CTLA-4 blockade overcomes immunotherapy resistance in KRAS-mutant gastric cancer

Science China Press
Peer-Reviewed Publication

A team led by researchers at Peking University Cancer Hospital & Institute reports that combining targeted KRAS inhibition with CTLA-4 immune checkpoint blockade overcomes the immunosuppressive microenvironment that renders KRAS-mutant gastric adenocarcinoma resistant to PD-1 immunotherapy. In a genetically faithful, immunocompetent mouse model of KRAS^G12D-driven gastric cancer, the combination suppressed TGF-beta signaling, impaired regulatory T cell function and elicited effective anti-tumor immunity. The study, published in Science China Life Sciences, provides a preclinical rationale for CTLA-4-based combination immunotherapy in this molecularly defined subset of patients.

Integration of photobiomodulation and nanomedicine: Recent advances and possible mechanisms for non-photoactive nanoparticles

Chinese Society for Optical Engineering
Peer-Reviewed Publication

Researchers are exploring a new frontier in nanomedicine by combining photobiomodulation, a low-intensity light-based therapeutic approach, with nanoparticles used for diagnosis and treatment. This review highlights how PBM may regulate nanoparticle interactions with cells and enhance intracellular delivery pathways. The study identifies key challenges and future directions for developing next-generation targeted nanotherapeutic strategies.
