Combination of anti-malarial drug and photosensitizer could effectively kill cancer cells

Artemisinin, a potent anti-malarial drug, has been widely hailed as a promising alternative cancer treatment. Scientists from the National University of Singapore recently showed that its anti-cancer properties could be enhanced by 10 folds when used in combination with Aminolaevulinic acid, a photosensitizer or a drug which, upon exposure to light, leads to generation of free radicals that can kill cells.

Epigenetic changes triggered by cigarette smoke may be earliest step in lung cancer development

Scientists at the Johns Hopkins Kimmel Cancer Center say they have preliminary evidence in laboratory-grown, human airway cells that a condensed form of cigarette smoke triggers so-called "epigenetic" changes in the cells consistent with the earliest steps toward lung cancer development.

Optimizing beer’s shelf life using benchtop EPR

The main challenges in optimizing beer shelf life is that most manufacturers can only perform accelerated shelf life testing on packaged beer. So, it's almost impossible to determine where in the process you've had a positive or a negative impact on the freshness of the beer.
