Late last year, an angler caught a smallmouth bass in the Susquehanna River near Duncannon, Pa. That fish, officials from the Pennsylvania Fish & Boat Commission said this week, had a malignant tumor.

Cancerous growths and tumors on fish are "very, very infrequent," John Arway, the agency's executive director, said in an interview.
"These cancers can be initiated by contaminants," he said.
Here's something that might sound strange: There are companies now that print and sell DNA.
This trend â which uses the term "print" in the sense of making a bunch of copies speedily â is making particular stretches of DNA much cheaper and easier to obtain than ever before. That excites many scientists who are keen to use these tailored strings of genetic instructions to do all sorts of things, ranging from finding new medical treatments to genetically engineering better crops.
Starting around 35,000 years ago, our ancestors painted â with accurate lines and glorious colors â images of lions, bison, mammoth, rhinoceroses, horses and even an owl on the walls of what is now called Chauvet Cave in south-central France.
