At first glance, it looks like a plain, slightly glossy sheet. Then it goes through a quick bath, the temperature shifts, and ...

This octopus-inspired smart skin can change shape and reveal hidden secrets on command.

TORONTO, Feb. 13, 2026 (GLOBE NEWSWIRE) -- Chinese New Year is traditionally Hong Kong’s grand festival, featuring a series of vibrant and diverse activities, including Chinese New Year flower markets ...

Scientists are exploring how DNA’s physical structure can store vast amounts of data and encode secure information.

Researchers unveil octopus-inspired smart skin that hides images, changes shape, and encodes data via 4D printing.

Learn about the groundbreaking 4D printed hydrogel that mimics cephalopod skin, transforming with heat and mechanical stress.

US researchers have developed a 4D-printing method for hydrogel ‘smart synthetic skin’ that hides and reveals images on demand, with potential uses in information encryption and adaptive camouflage.

Engineered DNA can store massive amounts of data while also encrypting it, opening the door to ultra-secure, long-term digital storage.

The key to the smart skin lies in a technique called halftone-encoded printing. The method translates digital image or texture data into binary patterns that are printed directly into the hydrogel.

Researchers at Penn State have developed a fabrication method that can print multifunctional “smart synthetic skin” —  configurable materials that can be used to encrypt or decrypt information, power ...

Since the dawn of the computer age, researchers have wrestled with two persistent challenges: how to store ever-increasing reams of data and how to protect that information from unintended access. Now ...
