Tracking Plasmodium knowlesi through faecal DNA for monitoring zoonotic transmission in wild macaques across Southeast and South Asia

We conducted the non-invasive surveillance of Plasmodium knowlesi in wild macaques using 4,752 faecal samples collected across nine endemic countries. 

Toxicity of plastic diesel exhaust in primary human airway epithelial cell cultures

Plastic pyrolysis oil, which can be produced with similar properties as diesel fuel (plastic diesel), can be used as an alternative to mineral diesel (ULSD) to run a diesel engine. This presents a potential method for recycling waste plastic. Typically plastic diesel is blended with mineral diesel, and oxygenated fuel additives such as ethers added to improve resulting fuel properties. 

FEF25–75% trajectories from age 7 to 53 years, associations with childhood and parental preconception factors, and midlife COPD risk: a prospective cohort study

Existing trajectory studies have emphasised large-airway indices, but chronic obstructive pulmonary disease (COPD) might originate in smaller airways. This study aimed to investigate mid-to-small-airway function trajectories, their associated factors, and COPD risk.

Stochastic models indicate rapid smallpox spread and mass mortality of Indigenous Australians after colonial exposure

The impact of smallpox (variola) on Aboriginal communities in Australia beginning in 1789 was catastrophic and continues to cause intergenerational trauma. Historically biased perspectives and contemporary misinformation of the disease's introduction and spread impede modern-day truth-telling and efforts towards reconciliation and national healing.

When ‘vape-free’ should mean ‘smoke-free’: third-hand e-cigarette residues and the developing lung

E-cigarettes are widely perceived as a safer alternative to tobacco, and that perception often extends to their use around infants and children. Yet exhaled aerosol deposits onto indoor surfaces, leaving a residue, known as third-hand e-cigarette aerosol, that can be re-emitted, ingested, or absorbed through the skin. The developmental consequences of such exposure have been almost entirely unexplored.
