Nano-machines made from DNA look like molecule-size hinges

For the very first time, engineers have used the DNA origami assembly method to build  complex DNA-based mechanism that performs a repeatable and reversible function. Mechanical engineers at The Ohio State University built their devices such that they may function like any regular macro-object, like opening and closing hinges. Their approach, however, is different than other DNA assembly projects which concentrated

This insect is the first known creature gifted by nature with ‘mechanical gears’

The Issus coleoptratus or issus for short is a small hopping insect that can leap at tremendous speeds and lengths compared to its tiny size. Actually, it’s one of the fastest accelerating creatures known to biologists, capable of accelerating at nearly 400 g’s—a rate more than 20 times what a human body can withstand. To achieve this fascinating feat the issus performs

Detecting explosives with an artificial dog nose

In an age where the developing world is shadowed by paranoia in face of waves of terrorist attacks, no measure of precaution is spared. Preventing terrorist attacks has been a top priority for governments for a long time, especially since 9/11, and detecting explosives at critical check-ins like airport and customs makes for the first line of the defense. While we’re

Inteligent shock absorbers dampen vibrations and generate power

Many efforts and funding have been put into countering vibrations, such as the ones produced by an internal combustion engine, to dampen shocks and reduce noise. Much progress has been made; you only need to compare two vehicles, one twenty years old, the other brand new, and you’ll instantly notice the differences. One, noisy and bumpy, the other silent and

New world record set for Rube Goldberg machine at 300 steps

Everybody enjoys a good ol’ entertaining Rube Goldberg machine, whether it’s a fantasy Loony Tunes contraption or a real-life state of the art display of engineering. What’s not to love when alarm clocks, sprockets, furniture and even boiling tea pots all work together in a lovely dance, ultimately ending in lighting a candle or something along the lines whose simplicity comes

Toy-inspired “Buckliball” paves the way towards a new class of engineering structures

Scientist at MIT and Harvard University teamed up to figure out what would be the simplest 3-D structure capable of collapsing and morphing due to instability. Their inspiration came after the scientists came across a popular toy, spherical in shape and fitted with movable parts and hinges, which allows it to easily dimple in size reversibly. Based on this toy, the

Arthur Ganson’s moving sculptures

Arthur Ganson is a mechanical engineer by trade and a kinetic sculptor at heart. His mechanized devices spur up spirit from cogs and wires, as his sculptures move with subtlety and grace, often in a chain reaction of energy à la Rube Goldberg. His creations are rooted inside deep philosophical concepts, but at the same time shine with an unparalleled
