Dating all the way back to at least the 17th century, there has been evidence of key guns used by jailers. The keys were filled with gun powder to create a primitive gun that could be detonated if there was any trouble when opening a cell door.
Portuguese designer Susana Soares has developed a device for detecting cancer and other serious diseases using trained bees. The bees are placed in a glass chamber into which the patient exhales; the bees fly into a smaller secondary chamber if they detect cancer.
Scientists have found that honey bees - Apis mellifera - have an extraordinary sense of smell that is more acute than that of a sniffer dog and can detect airborne molecules in the parts-per-trillion range.
Bees can be trained to detect specific chemical odours, including the biomarkers associated with diseases such as tuberculosis, lung, skin and pancreatic cancer.

The 3200 year old tree so massive that it had never been captured in a single image until recently.
This giant sequoia stands 247 feet tall and measures 45,000 cubic feet in volume. The trunk alone measures 27 feet and the branches hold 2 billion needles (more than any tree on the planet).
This picture took a team of photographers from Nat Geo, 32 days and stitching together 126 different photos to make.
This is so beautiful
