Cancer surgery is invariably difficult, in part, because doctors have always had a hard time determining exactly where the healthy tissue ends and the tumor begins. Not anymore. A new "intelligent knife" can actually sniff out the cancer cells during an operation and keep the doctor on track.

People who have been blind since a young age can sometimes learn to develop a sort of low-grade echolocation. This technique, used by the likes of Ray Charles, Stevie Wonder, Ronnie Milsap, and Ben Underwood, works much the same way as it does in bats and dolphins. But people who have just recently lost their sight can’t harness this ability innately. They need the vOICe to do it for them.

At least 35 million people around the planet live with HIV, and it kills over 1.7 million people each year, so the fact that it’s currently untreatable is one of the biggest medical problems of our time.

Contact lenses are great if your only issue is near or farsightedness, but for those struggling with age-related macular degeneration (AMD), a leading cause of blindness among older adults, those flimsy little lenses ain’t going to cut it—or at least not the kind of contact lenses you’re used to. But soon, AMD-sufferers could see their vision vastly improving thanks to a slim, adjustable telescope that sits right in the middle of their eye.

This map may look like a fairly reasonable representation of the world—but that’s all the more impressive when you realise it’s actually made up of microscopic cells from parts of the body that cause problems for people who live in each country.

Who needs gigantic dialysis machines? The first portable blood filter has just been approved for testing on humans, and it’s practically pocket-sized.

We’ve known for awhile that certain illnesses can have a very, er, special smell for the olfactory-inclined
