How do you work out if a fossilised creature originally sank or swam? You create a complex 3D model of its stricture using X-rays is how. As has been done with the 65-million-year-old ammonite. Read more >
There’s something inherently amazing about mid-air refuelling: two man-made machines, probably hundreds of miles from home, hooking up in mid-air and transferring aerial lifeblood from one to another. See more >
This aerial view shows all kinds of exposed geological features that are waiting to be explored: long rugged ridges, plunging great craters and even the occasional wide flat plain. Sadly, it's at least 34 million miles away. Read more >
This 3D scan shows a tangle of abnormal blood vessels beneath a patient’s skin, which caused speech and vision problems and could have ended his life. Amazingly, though, they have been removed using a pioneering full face transplant procedure. Read more >
This is one of the priciest pieces of pilots’ head gear ever constructed. The F-35 Gen III Helmet Mounted Display System (HMDS), with the tremendous price tag of £268,119, is so advanced that it lets pilots see through their own airframe.
The sparks from this US Marines helicopter form a starry ring around the edge of the blades — a the result of static electricity created by friction between the dust and the metal blades moving through the air. Read more >
