Scientists discover how air pollution triggers lung cancer

Scientists said Saturday they had identified the mechanism through which air pollution triggers lung cancer in non-smokers, a discovery one expert hailed as "an important step for science—and for society".

Sweeteners may be linked to heart disease risk, study suggests

A large study suggested Thursday that artificial sweetener could be associated with a higher risk of heart disease, however experts urged caution about the findings.

Scientists discover how air pollution may trigger lung cancer in never-smokers

A new mechanism has been identified through which very small pollutant particles in the air may trigger lung cancer in people who have never smoked, paving the way to new prevention approaches and development of therapies, according to late-breaking data [to be] reported at the ESMO Congress 2022 by scientists of the Francis Crick Institute and University College London, funded by Cancer Research UK. The particles, which are typically found in vehicle exhaust and smoke from fossil fuels, are associated with non-small cell lung cancer (NSCLC) risk, accounting for over 250,000 lung cancer deaths globally per year.

Immune cells engineered to battle cancer can be turned 'on' or 'off'

The billions of immune cells that help protect us from diseases do amazing things, but sometimes they need a little boost. For decades, scientists have been trying to figure out ways to engineer living immune cells to better combat aggressive diseases, like cancer.
