Are silver nanoparticles a silver bullet against microbes?
Antimicrobials are used to kill or slow the growth of bacteria, viruses and other microorganisms. They can be in the form of antibiotics, used to treat bodily infections, or as an additive or coating on commercial products used to keep germs at bay......»»
Chromo-encryption method uses color to encode information
In a new approach to security that unites technology and art, EPFL researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to encode messages......»»
New models shed light on life"s origin
The first signs of life emerged on Earth in the form of microbes about four billion years ago. While scientists are still determining exactly when and how these microbes appeared, it's clear that the emergence of life is intricately intertwined with.....»»
Fleeting interactions between the smallest phytoplankton and bacteria help to shape global ocean productivity
Microorganisms, or microbes, are the engines driving large-scale ecological and biogeochemical processes in the ocean......»»
Current microbiome analyses may falsely detect species that are not actually present
Common approaches to analyzing DNA from a community of microbes, called a microbiome, can yield erroneous results, in large part due to the incomplete databases used to identify microbial DNA sequences. A team led by Aiese Cigliano of Sequentia Biote.....»»
Microbes are "active engineers" in Earth"s rock-to-life cycle
The name "critical zone" may give off 1980s action thriller vibes, but it's the term scientists use to refer to the area of Earth's land surface responsible for sustaining life. A relatively small portion of the planetary structure, it spans from the.....»»
Silver nanoparticles show promise in fighting antibiotic-resistant bacteria
In a new study, scientists with the University of Florida have found that a combination of silver nanoparticles and antibiotics is effective against antibiotic-resistant bacteria......»»

Microbes in your food can help or hinder your body"s defenses against cancer
The microbes living in your food can affect your risk of cancer. While some help your body fight cancer, others help tumors evolve and grow......»»
Discovering unique microbes made easy with new software platform
Microbes are foundational for life on Earth. These tiny organisms play a major role in everything from transforming sunlight into the fundamental molecules of life. They help to produce much of the oxygen in our atmosphere. They even cycle nutrients.....»»
Using bottlebrush-shaped nanoparticles, researchers can identify and deliver synergistic combinations of cancer drugs
Treating cancer with combinations of drugs can be more effective than using a single drug. However, figuring out the optimal combination of drugs, and making sure that all of the drugs reach the right place, can be challenging......»»
New shield blocks electromagnetic interference while allowing wireless optical signals
Researchers have experimentally demonstrated, for the first time, a mechanically flexible silver mesh that is visibly transparent, allows high-quality infrared wireless optical communication and efficiently shields electromagnetic interference in the.....»»
Microbes could be used by farmers as natural fertilizer for poor soil
A study published in The ISME Journal identified 522 genomes of archaea and bacteria associated with the roots and soil of two plant species native to the Brazilian montane savanna ecoregion known as campos rupestres ("rocky meadows"). Hundreds of mi.....»»
In the core of the cell: New insights into the utilization of nanotechnology-based drugs
Novel drugs, such as vaccines against COVID-19, among others, are based on drug transport using nanoparticles. Whether this drug transport is negatively influenced by an accumulation of blood proteins on the nanoparticle's surface was not clarified f.....»»
Rare opportunity to study short-lived volcanic island reveals sulfur-metabolizing microbes
In 2015, a submarine volcano in the South Pacific erupted, forming the Hunga Tonga Hunga Ha'apai island, destined to a short, seven-year life. A research team led by the University of Colorado Boulder and Cooperative Institute for Research in Environ.....»»
New nanoparticles deliver therapy throughout the brain and edit Alzheimer"s gene in mice
Gene therapies have the potential to treat neurological disorders like Alzheimer's and Parkinson's diseases, but they face a common barrier—the blood-brain barrier. Now, researchers at the University of Wisconsin-Madison have developed a way to mov.....»»
Our future climate depends partly on soil microbes—but how are they affected by climate change?
The largest terrestrial carbon sink on Earth is the planet's soil. One of the big fears is that a warming planet will liberate significant portions of the soil's carbon, turning it into carbon dioxide (CO2) gas, and so further accelerate the pace of.....»»
Chemical navigation: Scientists develop a water remediation method using nanoparticles
Chemists from St Petersburg University have developed a method for purifying water from organic compounds using tin oxide nanoparticle based photocatalysts. The findings of the research are published in the Journal of Alloys and Compounds ......»»
Unconventional experiments produce new nanoscale particles with big potential
Nanoparticles are complex materials smaller than 100 nanometers, or about the size of a virus, but they have a large range of potential applications, from medicine to energy to electronics. Now, hundreds of new nanoparticles with previously unknown f.....»»
Our toilets can yield excellent alternatives for widespread polluting fertilizers
To tackle the climate crisis, biodiversity loss, and pollution, humanity will need to move to a circular economy, where all resources are recycled. Why not recycle our own body waste too as fertilizer, provided there is no risk that harmful microbes.....»»
The world in grains of interstellar dust
Understanding how dust grains form in interstellar gas could offer significant insights to astronomers and help materials scientists develop useful nanoparticles......»»
