A new antimicrobial cotton textile with Cu ions in nanofibers
Cotton textiles are ubiquitous in daily life, and they are also one of the primary mediums for transmitting viruses and bacteria. Conventional approaches to fabricating antiviral and antibacterial textiles generally load the functional additives onto.....»»
Researchers design a flexible system that sidesteps copper-protein binding
It may seem counterintuitive to many, but metal ions play a critical role in life, carrying out some of the most important biological processes. Think of hemoglobin—a metalloprotein responsible for carrying oxygen to the body's organs via red blood.....»»
IonQ’s new ions have lower error, great performance on a new benchmark
How do you compare the performance of systems based on very different technologies? Enlarge / A cartoon diagram of the trapped ion system. (credit: IonQ) Back in 2020, we talked to the CEO of a quantum computing startup called.....»»
Combining tree rings, rainfall, streamflow records to reconstruct Daly River"s climatic history
Plans to allocate water from the Northern Territory's (NT) Daly River to cotton plantations could be based on overly optimistic expectations about streamflow, a new study of tree rings in the area has found......»»
Metal mix and match: An unexpected discovery could improve the crystallinity of coordination nanosheets
Coordination nanosheets are a new and emerging class of two-dimensional materials, rapidly gaining importance in the field of nanomaterials. They consist of metal ions and organic ligand molecules, linked to each other to form one framework, via coor.....»»
Tiny thermometer directly monitors changes in temperature when ions pass through a nanopore
Scientists from SANKEN (the Institute of Scientific and Industrial Research) at Osaka University measured the thermal effects of ionic flow through a nanopore using a thermocouple. They found that under most conditions, both the current and heating p.....»»
Inspired by insects, engineers create spiky materials that could pop bacteria
Researchers have created intricately patterned materials that mimic antimicrobial, adhesive and drag reducing properties found in natural surfaces......»»
Agricultural fungicides may be driving antimicrobial resistance
New research from the University of Georgia has shown, for the first time, that compounds used to fight fungal diseases in plants are causing resistance to antifungal medications used to treat people......»»
Silver and chemicals found in wine and chocolate used to create antimicrobial textile coating
For the first time, researchers have found a cost-effective and convenient way to apply a silver-based antimicrobial clear coating to new or existing textiles. Their method uses polyphenols, commonly found in food items notorious for staining clothes.....»»
How to get chloride ions into the cell
Many bacteria and unicellular algae have light-driven pumps in their cell membranes: proteins that change shape when exposed to photons such that they can transport charged atoms in or out of the cell. Thanks to these pumps, their unicellular owners.....»»
A device based on 3D transistor arrays for collecting intra and inter-cellular recordings
Animal cells can use elements or ions to generate electrical impulses. These impulses are then conveyed from one cell to another, traveling across cellular networks......»»
New approach transports trapped ions to create entangling gates
Trapped ions excited with a laser beam can be used to create entangled qubits in quantum information systems, but addressing several stationary pairs of ions in a trap requires multiple optical switches and complex controls. Now, scientists at the Ge.....»»
Antimicrobial Resistance Now a Leading Cause of Death Worldwide, Study Finds
An anonymous reader quotes a report from The Guardian: Antimicrobial resistance poses a significant threat to humanity, health leaders have warned, as a study reveals it has become a leading cause of death worldwide and is killing about 3,500 people.....»»
Measuring medicine use in livestock supports the fight against antimicrobial resistance
Measuring how much antimicrobial medication is given to food animals is key to understanding how to slow antimicrobial resistance, when dangerous microbes get so used to antimicrobials that they evolve stronger defenses against them. However, measuri.....»»
Exploring oxygen ions in Jupiter"s innermost radiation belts
Planets like Earth, Jupiter and Saturn, with global magnetic fields of their own, are surrounded by so-called radiation belts: Trapped in the magnetic field, fast moving charged particles such as electrons, protons, and heavier ions whiz aroun, thus.....»»
Researcher develops soft material to preserve biological medicines
As superbugs become increasingly dangerous to human health, NC State researchers have developed a soft material that preserves medicines capable of treating infections without the risk of antimicrobial resistance......»»
Gene discovered in Georgia water a possible global threat
A gene that causes bacteria to be resistant to one of the world's most important antibiotics, colistin, has been detected in sewer water in Georgia. The presence of the MCR-9 gene is a major concern for public health because it causes antimicrobial r.....»»
Seeing the plasma edge of fusion experiments in new ways with artificial intelligence
To make fusion energy a viable resource for the world's energy grid, researchers need to understand the turbulent motion of plasmas: a mix of ions and electrons swirling around in reactor vessels. The plasma particles, following magnetic field lines.....»»
CES 2022: Frontier aims to create a digital textile metaverse
Digital transformation has touched every industry around the world. However, because the textile industry chain is extremely long and complicated, the process of digitalization has become equally complicated......»»
Plasma-based engineering creates contact-killing, antifouling, drug-release surfaces
The deepening concern over antibiotic-resistant infections, coupled with prevailing hospital-acquired infections from surgical tools, implants, and heavily touched surfaces, has ramped up antimicrobial material development in recent years......»»
