There's no limit to viral ruthlessness. These lifeless packets of genetic code cause countless ails, often without a known cure. One such monster spends most of its time as a seemingly benign strand of DNA that could sit latent for years before striking, causing cells to turn into a rare but aggressive form of skin cancer called Merkel cell carcinoma.

In a study that's bound to attract considerable controversy, a pair of researchers are claiming that between 60 and 66 per cent of all cancer-causing mutations are the result of random DNA copying errors, making them essentially unavoidable. The new research is offering important insights into how cancer emerges, and how it should be diagnosed and treated — but many questions remain.
Following the deaths of five patients, Juno Therapeutics has decided to pull the plug on an experimental cancer treatment that boosts the power of a patient's immune cells. The news comes just days after the company's rival, Kite Pharma, announced its success with a similar method, showing there's still hope for this potentially revolutionary gene therapy.
We already knew smoking was bad for our lungs, but a new study shows exactly how many DNA mutations per cell are caused by sucking on those nicotine sticks. If you're interested in obsessively quantifying your bad life choices, know that smoking a pack a day will lead to approximately 150 mutations per lung cell each year.
