Jun 24, 2024 (Nanowerk News) Counterfeiters are getting increasingly more sophisticated in forging everything from diplomas and currency, to medications and artwork. While protective measures such as luminescent markings (which glow under ultraviolet light) have been around for a while, forgers have figured out how to exploit the weaknesses in...
Researchers propose the next platform for brain-inspired computing
Jun 24, 2024 (Nanowerk News) Computers have come so far in terms of their power and potential, rivaling and even eclipsing human brains in their ability to store and crunch data, make predictions and communicate. But there is one domain where human brains continue to dominate: energy efficiency. “The most...
Uniting DNA origami and CRISPR to enhance detection of genetic mutations in cancer diagnostics
Jun 24, 2024 (Nanowerk Spotlight) The detection of genetic mutations in circulating tumor DNA (ctDNA) has long been a critical challenge in cancer diagnostics and personalized medicine. Traditional methods like polymerase chain reaction (PCR) and next-generation sequencing have limitations in sensitivity and accuracy, especially when dealing with minute quantities of...

Towards edible robots and robotic food
Jun 21, 2024 (Nanowerk News) Robots and food have long been distant worlds: Robots are inorganic, bulky, and non-disposable; food is organic, soft, and biodegradable. Yet, research that develops edible robots has progressed recently and promises positive impacts: Robotic food could reduce electronic waste, help deliver nutrition and medicines to...
seekRNA delivers a new pathway for accurate gene editing
Jun 21, 2024 (Nanowerk News) Scientists at the University of Sydney have developed a gene-editing tool with greater accuracy and flexibility than the industry standard, CRISPR, which has revolutionised genetic engineering in medicine, agriculture and biotechnology. SeekRNA uses a programmable ribonucleic acid (RNA) strand that can directly identify sites for...
Controlling electronics with light: the magnetite breakthrough
Jun 21, 2024 (Nanowerk News) Researchers at EPFL have discovered that by shining different wavelengths (colors) of light on a material called magnetite, they can change its state, e.g. making it more or less conducive to electricity. The discovery could lead to new ways of designing new materials for electronics...
Scientists discover new behavior of membranes that could lead to unprecedented separations
Jun 21, 2024 (Nanowerk News) Imagine a close basketball game that comes down to the final shot. The probability of the ball going through the hoop might be fairly low, but it would dramatically increase if the player were afforded the opportunity to shoot it over and over. A similar...
