Never too late to quit — protective cells could cut risk of lung cancer for ex-smokers
Protective cells in the lungs of ex-smokers could explain why quitting smoking reduces the risk of developing lung cancer, Cancer Research UK-funded researchers have determined. Scientists from the Wellcome Sanger Institute and UCL have discovered that compared to current smokers,…
Butt emissions: Study finds even extinguished cigarettes give off toxins
Cigarette butts pile up in parks, beaches, streets and bus stops, places where all types of littering are frowned upon. Best estimates are that over five trillion butts are generated by smokers each year worldwide, and concern about their environmental…

Novel molecules display potent and selective action against ovarian tumor cells
Compounds based on palladium, a metal belonging to the same group as platinum, have been developed by researchers from Brazil, the UK and Italy — In vitro tests show action against tumor cells that are resistant to treatment currently used
What’s in your water?
Researchers identify new toxic byproducts of disinfecting drinking water
Major Asia gene study to help doctors battle disease
An ambitious new study of genes in Asian populations is filling in big gaps in our understanding of human genetics, shedding light on the history of human migration and ultimately aiming to improve our ability to treat disease. Researchers from…

Snake stem cells used to create venom-producing organoids
Organoids have become an important tool for studying many disease processes and testing potential drugs. Now, they are being used in a surprising and unexpected way: for the production of snake venom. On January 23 in the journal Cell ,…
Chemicals in the environment: A focus on mixtures
Combined chemical and bioanalytical methods are able to efficiently characterize chemical mixtures
Venom-producing snake organoids developed in the lab
Researchers from the group of Hans Clevers at the Hubrecht Institute (KNAW), in an international collaboration, have developed a method to grow snake venom gland cells as organoids. These lab-grown mini glands produce and secrete active toxins found in snake…
