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......»»
Researchers discover that various species share a similar mechanism of molecular response to nanoparticles
Researchers at FHAIVE (Finnish Hub for Development and Validation of Integrated Approaches), Tampere University, have discovered a new response mechanism specific to exposure to nanoparticles that is common to multiple species......»»
Viruses could reshuffle the carbon cycle in a warming world
Microbes play important roles in ecosystems, and these roles are changing with global warming. Scientists also now know that most types of microbes are infected by viruses, but they know relatively little about how these viral infections could change.....»»
Reconstructing ancient bacterial genomes can revive previously unknown molecules, a potential source for new antibiotics
Microorganisms—in particular bacteria—are skillful chemists that can produce an impressive diversity of chemical compounds known as natural products. These metabolites provide the microbes major evolutionary advantages, such as allowing them to i.....»»
Chemists find that metal atoms play key role in fine organic synthesis
A small team of chemists at the Russian Academy of Sciences, has found that metal atoms, not nanoparticles, play the key role in catalysts used in fine organic synthesis. In the study, reported in the Journal of the American Chemical Society, the gro.....»»

Machine learning helps scientists identify the environmental preferences of microbes
Researchers have figured out a way to predict bacteria's environmental pH preferences from a quick look at their genomes, using machine learning. Led by experts at the University of Colorado Boulder, the new approach promises to help guide ecological.....»»
Field experiment reveals "blinding" is not a silver bullet to deal with gender bias
Women and people far from corporate headquarters often need help to get recognition for their ideas. One way to help is to put all ideas on equal footing through a "blinding" strategy......»»
Iron oxide nanoparticles for medical applications: Study clarifies effect of microstructure on magnetic properties
Iron oxide nanoparticles are often used in medical technology as contrast agents for magnetic resonance imaging or as transport agents for drugs in the bloodstream, for example in tumor therapy. For these applications, the nanoparticles have to be bi.....»»
Using microbes to get more out of mining waste
Researchers have developed a new mining technique which uses microbes to recover metals and store carbon in the waste produced by mining. Adopting this technique of reusing mining waste, called tailings, could transform the mining industry and create.....»»
Backwashing affects the removal of micropollutants and the dynamic changes in the microbial community in sand filters
Sand filters are commonly applied in drinking water treatment and can efficiently remove suspended solids, organic matter, and microorganisms from source water. During the process, particulate matter and microbes can attach to filter sands and develo.....»»
Researchers use nanoparticles to increase light frequency and resolution of imaging systems
Physicists at the Australian National University (ANU) are using nanoparticles to develop new sources of light that will allow us to "peel back the curtain" into the world of extremely small objects—thousands of times smaller than a human hair—wi.....»»
What microbes can tell us about life on Earth and in space
Microbes are just about everywhere, from the soil to the air to Arctic ice to oceans, lakes, and rivers—not to mention all over your body and the phone or computer you're using right now......»»
Aerial root mucilage fixes atmospheric nitrogen to support plant growth
Plant-associated microbes play an important role in host nutrient utilization, stress tolerance, plant health, and adaptation. Identifying the key mucilage compound and friendly microbe, as well as their protective association with diazotrophic micro.....»»
Plastic-eating bacteria are amazing. But they aren’t going to save the planet
I hate to be the bearer of bad news, but plastic-eating bacteria aren’t going to save the planet. Here's why they aren’t a silver bullet for the environment......»»
Subsurface microbes capture toxic uranium and remediate groundwater
A new research study describes a previously unknown chemical process for removal of uranium from groundwater. Deep down in the bedrock, in an oxygen-free environment, microbes assist in the process of turning uranium "into rock." This finding might b.....»»
Using solar farms to generate fresh desert soil crust
In the arid regions of the American Southwest, an unseen world lies beneath our feet. Biocrusts, or biological soil crusts, are communities of living organisms. These industrious microbes include cyanobacteria, green algae, fungi, lichens, and mosses.....»»
Metallophiles and their bioremediation applications
Certain species of microbes have evolved to survive in harsh environments, even those that were previously thought to be too extreme to support life. These include environments, such as mines and industrial sewage, that are rich in heavy metals. On t.....»»
