A team at the Wyss Institute and Harvard SEAS has developed a new micro-scale printing method to create transformable objects. These “4D-printed” objects go a step beyond 3D printing to incorporate a fourth dimension–time.
The method was inspired by the way plants change shape over time in response to environmental stimuli. This orchid-shaped structure is printed with a hydro gel composite ink containing aligned cellulose fibrils, which enable an-isotropic swelling. A proprietary mathematical model developed by the team precisely predicts how the fibrils will swell in water. Continue reading →

Demolished twenty-one years ago (March 1993 – April 1994) city was empire of little houses stacked on top of each other, connected by staircases snaking under dangling wires, through corridors so dark even police were rumored to be afraid of them. A virtually lawless labyrinth of crime, grime, commerce and hope. After all, the Walled City was a kind of historical accident. A former Qing dynasty fortress, it never fully came under the regulation Continue reading →
During the World Cup slalom skiing championship on Wednesday, ski champion Marcel Hirscher was nearly hit by an out-of-control camera drone, that crashed just behind him while filming during a run. The pilot was accredited and allowed to fly the quad, but only over a corridor where no spectators were present. Continue reading →
