Tobacco Smoke Linked to Mutations That “Stop” Cancer-Fighting Proteins

A new study has revealed that tobacco smoke can cause specific DNA changes that can prevent anti-cancer proteins from being fully constructed, representing one way that tobacco smoking causes cancer.

Renting Rather Than Owning a Home Linked to Faster Biological Aging

A new study has shown that renting a home, rather than outright home ownership, has been linked to faster biological aging – the deterioration and accumulation of damage in our cells.
