The chances of two people sharing identical fingerprints are incredibly slim—about 1 in 640 billion. Even identical twins, who share the same DNA, have unique fingerprint patterns. Now, scientists have taken this uniqueness a step further with the development of a revolutionary electronic skin that features artificial fingerprints with a probability of duplication 10²³² times lower than human fingerprints.

A research team led by Professor Kyoseung Sim from the Department of Chemistry at UNIST (Ulsan National Institute of Science and Technology) has unveiled this cutting-edge electronic skin technology in a recent Nature Communicationspublication. The breakthrough could lay the groundwork for future AI-powered robots to possess uniquely identifiable fingertips—offering capabilities previously exclusive to biological organisms.

Researchers at Pohang University of Science and Technology (POSTECH) have developed a high-entropy alloy (HEA) that maintains both strength and flexibility across an exceptionally wide temperature range—from -196 °C to 600 °C. This breakthrough opens new possibilities for use in aerospace, automotive, and energy industries where materials are exposed to extreme or fluctuating temperatures.

The research team, led by Professor Hyoung Seop Kim from the Department of Materials Science and Engineering, the Graduate Institute of Ferrous Technology, and the Department of Mechanical Engineering at POSTECH, published their findings in the international journal Materials Research Letters.

A team of researchers has developed a pioneering methodology to replace diesel engines on ferry boats with pneumatic propellers, offering a cleaner, quieter, and potentially more cost-effective alternative for maritime transport.

The study, published in Energy Conversion and Management, outlines a system in which two air motors, each generating 250 kW, successfully powered a ferry along a fixed route in Finland’s maritime transport system. The experimental system demonstrated that pneumatic propulsion could meet the same performance standards as traditional diesel engines, but with significantly reduced environmental impact.

A new scientific breakthrough could dramatically improve cancer treatments by helping bulky, hard-to-deliver drugs enter cells more efficiently.

Researchers from Duke University, the University of Texas Health Science Center at San Antonio, and the University of Arkansas have discovered a way to significantly boost the cellular uptake of a promising class of cancer therapies known as PROTACs. These drugs work by degrading harmful proteins in cells but are often too large to penetrate cell membranes on their own.

The team found that a naturally occurring cell surface protein, CD36, can act as a transporter, helping PROTACs cross the cellular barrier. By modifying the drugs to exploit this transport mechanism, the researchers achieved up to 22.3 times higher drug uptake, resulting in up to 23 times more powerful tumor suppression—all without sacrificing drug stability or solubility. Their findings, published April 17 in Cell, could breathe new life into many large-molecule drugs previously deemed too unwieldy for therapeutic use.

The development of increasingly advanced sensors is driving progress in fields such as robotics, security systems, virtual reality (VR), and high-tech prosthetics. Among these, multimodal tactile sensors—which detect various types of touch-related data like pressure, texture, and material composition—stand out for their potential to replicate the human sense of touch.

Despite significant advances in tactile sensor technology, two major challenges persist: detecting both the direction and magnitude of applied forces, and accurately identifying the materials that objects or surfaces are made from. Many existing sensors struggle to overcome these limitations.

Researchers at the University of Tokyo have developed a new method for growing lab-cultured chicken meat that mimics natural blood vessel systems, offering a potential breakthrough in the production of realistic, ethical alternatives to conventional meat. The team successfully produced nugget-sized pieces of chicken muscle using a bioreactor equipped with artificial vessels that deliver nutrients and oxygen evenly throughout the tissue—one of the major challenges in lab-grown meat production.

The innovation centers on a device called a perfusable hollow fiber bioreactor, which uses tiny, tube-like structures to replicate the function of blood vessels. These artificial vessels not only keep the cells alive by providing a steady supply of oxygen and nutrients but also guide muscle cell growth through microscopic anchors that help align the tissue properly.
