A 40-year-old patent has finally been brought to life.
That's the Y-zipper.
A 3D-printed three-sided fastener that transitions any object from flexible to rigid and back again.
The robotics application is the one that caught my attention.
A quadruped robot that adjusts its leg stiffness depending on terrain, switching between rigid and flexible in real time without additional motors or complex mechanical systems.
But this goes way beyond robotics. A wrist cast that loosens during the day and stiffens at night. A tent that pops into shape in 90 seconds instead of six minutes.
The idea sat in a patent filing for four decades. It took 3D printing to finally make it real.

In 2003, Drew Carey reportedly smoked before filming the final Whose Line Is It Anyway? sketch of the episode. As a result, the rest of the cast opted to mess with him throughout the bit instead of sticking to a normal performance.
What the Artemis II astronauts did over the last 10 days was a testament to their bravery. And the fact that they traveled farther from Earth than anyone ever has, re-entered our atmosphere at more than 24,000 mph, and splashed down safely was a testament to human ingenuity. Thanks to everyone at @NASA for making this mission possible, and for taking us along for the ride.
अब अमेरिका को ईरान से भाग ही जाना चाहिए... ज्यादा इज्जत उतरी तो सालों तक असर रहेगा।
हाथी भी लंगड़ा हो तो कुत्ते भी नोंच डालते हैं, इस बार शेर से पाला पड़ा है।

Absolute disaster. A former US Ambassador admits on live TV that the US has "already lost" the war because the Strait of Hormuz is only closed due to America starting the conflict. He confesses the goal was regime change, it failed, and now Trump is just "making it up."
Conan is one of the greatest awards show host I’ve ever seen. He’s funny, respectful, and cool under pressure. A true natural here and should host as long as he wants.
Lewis: “to be up here with him whilst he got his first pole, and now to get the first win.. It’s truly special – I remember getting my first [win]…”
Kimi: “I was one year old, by the way.”
Lewis: “You were born in 2006, right? That’s ridiculous!” 🤣🤣🤣
A rotating ball casts a shadow that perfectly matches a mass on a spring, revealing how circular motion and simple harmonic motion are linked. A visual proof of sine-wave physics in action.
Did you know?
NASA only uses 15 digits of π for calculating interplanetary travel.
At 40 digits, you could calculate the circumference of a circle the size of the visible universe with an accuracy that'd fall off by less than the diameter of a hydrogen atom.
