Jason Allemann, who created these Lego mazes last year, built this beautiful and elegant Lego ball clock. The video shows how the rail system works with one ball being hauled up the chain every minute, then tipping the balance once enough balls have accumulated.

A father who lost his arm in an accident six years ago has been given a new lease of life by a hi-tech bionic hand which is so precise he can type again. Nigel Ackland, 53, has been fitted with the Terminator-like carbon fibre mechanical hand which he can control with movements in his upper arm. The new bebionic3 myoelectric hand, which is also made from aluminium and alloy knuckles, moves like a real human limb by responding to Nigel’s muscle twitches. Incredibly, the robotic arm is so sensitive it means the father-of-one can touch type on a computer keyboard, peel vegetables, and even dress himself for the first time in six years.

Twin Cats Always Mirror Each Other in Sleep
Scientists are baffled by twin cats, Merry and Pippin, who reportedly always sleep in an exact mirror image of one another.
“Even if we place them in disparate starting positions or in separate rooms, they somehow always wind up sleeping exactly like the other,” said leading cat biologist and feline sleep expert Dr. Tobias Winslow. ”I’ve never seen anything like it.”
A polysomnogram revealed nothing out of the ordinary about the cats’ brain functions, eye movements, muscle activity, breathing or heart rhythms. ”We had expected to find that Merry and Pip were synched up on an internal level,” explained Winslow, “but it is literally just in the way they position their bodies for slumber.”
More tests will be done later this month during a scheduled comprehensive sleep study.
