The "Sareh Twist": A Hidden Principle Unlocked in Origami Structures
Researchers have identified and formalized an internal twist mechanism — dubbed the "Sareh twist" — lurking in origami tessellations derived from the Miura fold. The discovery shows that paper cones and tubes naturally fold under external loads using this mechanism, and that accounting for it can dramatically improve the efficiency and predictability of foldable aerospace and biomedical structures.

McGill University researchers have developed ultra-thin graphene oxide sheets that fold, move, and reshape themselves like origami — controlled by humidity or magnetic fields. Remarkably, the material can simultaneously act as an actuator and a sensor, detecting its own bending through changes in electrical conductivity. Potential applications include surgical tools, soft robotics, and smart wearables.

NSF-supported researchers are designing complete robots using automatically generated origami fold patterns — no origami expertise required. One project features underwater robots that change body shape to jet-propel themselves like squids. Because origami fabrication is fast and cheap, full working robots could soon be designed and built in hours rather than months, opening a new era of deployable, adaptive machines.

14-year-old Miles Wu discovered that a single sheet of paper folded into the Miura-ori origami pattern can support up to 10,000 times its own weight. He turned this insight into a rigorous structural engineering project, testing dozens of fold geometries to find the strongest, most compact designs — with the goal of creating low-cost emergency shelters that can be rapidly deployed after disasters.

University of Michigan engineers are exploring how origami fold patterns can be used to engineer materials with properties that don't exist in nature — including structures that become stiffer the harder you compress them, or that change their acoustic and thermal properties on demand. These "mechanical metamaterials" could revolutionize impact protection, sound dampening, and shape-shifting architecture.

Because every art form needs to not take itself too seriously
- Why don't origami artists ever lose at poker? They always know when to fold.
- I started an origami business. It folded within a week.
- I got into an argument with an origami artist. He really knew how to make sharp points.
- My therapist says I need to stop folding under pressure. She's clearly never met an origami deadline.
- Why did the origami artist go to therapy? He had too many unresolved creases.
- Why don't origami artists ever get lost? They always know how to find their way back to square one.
- I asked my origami instructor if I was improving. He studied my work for a long time, then very carefully folded it into the bin.
- I asked a master origami artist the secret to his success. He said "it's all in the details," then handed me a 400-step diagram.
- Why was the origami artist so calm during the earthquake? He was used to things folding unexpectedly.
- My wife said she was leaving me because of my origami obsession. I didn't see it coming — but looking back, the signs were all there. I just couldn't read between the folds.
Tips for Beginners
What I wish I'd known before I started
Learn the four basic folds first
Everything in origami is built on four moves: the valley fold, mountain fold, squash fold, and reverse fold. Master these before touching a complex diagram and the rest becomes pattern recognition rather than guesswork.
Crease sharp and crease once
A blurry crease is harder to fix than a wrong one. Use a fingernail or a bone folder to press each fold flat all the way to the edge. Sloppy early creases compound into big misalignments by step 50.
Start bigger than you think you need to
Beginners almost always grab paper that is too small. A 20 cm (8 in) sheet gives your fingers room to work accurately. Once you can fold a model cleanly at that size, shrink it down for a tidier result.
Work on a hard, flat surface
Folding in the air or on a soft surface makes precise alignment nearly impossible. A table, hardcover book, or cutting mat keeps the paper stable and makes it much easier to line up edges and corners exactly.
Choose the right paper for the model
Standard kami (the colored squares sold in origami packs) is ideal for learning — it holds creases well and is forgiving of small mistakes. Avoid thick cardstock and printer paper until you understand how the model moves.
Pre-crease before you collapse
When a diagram calls for a sink, petal fold, or other collapse, fold and unfold each crease first so the paper knows exactly where to go. Trying to force a collapse on stiff, unscored paper is the fastest way to tear it.
Watch a video for tricky steps, then close it
Video tutorials are great for visualizing a confusing fold, but avoid following them step-by-step for the whole model. Reading and interpreting diagrams yourself is a skill worth building — it unlocks access to thousands of models with no video equivalent.
Dry hands, clean paper
Moisture from your hands weakens paper fibers and makes foil wrinkle permanently. Wash and dry your hands before a long session, keep drinks away from the table, and store unfolded sheets flat in a sleeve or folder.
Expect to fold each model more than once
The first attempt teaches you where the model is going. The second attempt is where you actually fold it well. Many folders do three or four runs of a new design before they're happy with the result — that's normal, not failure.
Difficulty ratings are relative — find your baseline
A model labeled "intermediate" on one site may be labeled "complex" on another. Ignore the tags and browse diagrams by looking at the crease pattern or step count. If you can recognize the base being used, you can probably fold it.
