Jan 07, 2025 (Nanowerk News) Numerous memory types for computing devices have emerged in recent years, aiming to overcome the limitations imposed by traditional random access memory (RAM). Magnetoresistive RAM (MRAM) is one such memory type which offers several advantages over conventional RAM, including its non-volatility, high speed, increased storage...
The carbon in our bodies probably feft the galaxy and came back on cosmic ‘conveyer belt’
Jan 06, 2025 (Nanowerk News) Life on Earth could not exist without carbon. But carbon itself could not exist without stars. Nearly all elements except hydrogen and helium — including carbon, oxygen and iron — only exist because they were forged in stellar furnaces and later flung into the cosmos...
Compact terahertz sensor identifies cancer types with record sensitivity and 93% accuracy
Jan 06, 2025 (Nanowerk Spotlight) Cancer screening typically requires large, expensive equipment housed in specialized facilities. Current methods rely on chemical analysis of blood samples, microscopic examination of tissue biopsies, or complex imaging machines. Each approach demands extensive infrastructure: clinical laboratories, expensive equipment, and highly trained specialists to prepare samples...
New quantum sensing technology reveals sub-atomic signals
Jan 06, 2025 (Nanowerk News) Since the 1950s, scientists have used radio waves to uncover the molecular “fingerprints” of unknown materials, aiding in tasks as varied as scanning the human body with MRI machines and detecting explosives at airports. These methods, however, rely on signals averaged from trillions of atoms,...
Big leap forward for environmentally friendly graphene e-textiles technology
Jan 06, 2025 (Nanowerk News) A research team led by the University of Southampton and UWE Bristol has shown wearable electronic textiles (e-textiles) can be both sustainable and biodegradable. A new study, which also involved the universities of Exeter, Cambridge, Leeds and Bath, describes and tests a new sustainable approach...
New method turns e-waste to gold
Jan 03, 2025 (Nanowerk News) A Cornell University-led research team has developed a method for extracting gold from electronics waste, then using the recovered precious metal as a catalyst for converting carbon dioxide (CO2), a greenhouse gas, to organic materials. The method could provide a sustainable use for some of...
Detecting disease with only a single molecule
Jan 03, 2025 (Nanowerk News) UC Riverside scientists have developed a nanopore-based tool that could help diagnose illnesses much faster and with greater precision than current tests allow, by capturing signals from individual molecules. Since the molecules scientists want to detect – generally certain DNA or protein molecules – are...
New nanocrystal material a key step toward faster, more energy-efficient computing
Jan 03, 2025 (Nanowerk News) Scientists have taken a key step toward faster, more energy-efficient artificial intelligence, and data processing in general, with the discovery of luminescent nanocrystals that can be quickly toggled from light to dark and back again. “The extraordinary switching and memory capabilities of these nanocrystals may...
