Protective molecules facilitate molybdate anion binding to create novel silver nanoclusters
Silver nanocluster synthesis, or the binding of a silver atom to negatively charged anions, is often plagued by stability, sizing uniformity and surface composition issues. Protective molecules that bind the surface of silver nanoclusters, called lig.....»»
Research examines differences, and surprising similarities, between northern and southern silver birches
Antti Tenkanen's doctoral research focused on silver birch trees originating from different latitudes across Finland and, using both field and growth chamber experiments, he explored their traits and capacity to acclimate and adapt to climate change......»»
How microbes may help mitigate mercury absorption
New research by a team at Pennsylvania State University suggests that microbes in the human gut could be harnessed to help the body absorb useful nutritional metals—like iron, which is critical for red blood cells—and block or even remove the abs.....»»
An element essential to life discovered on one of Saturn"s moons, raising hopes of finding alien microbes
Enceladus is the tiny moon of Saturn that seems to have it all. Its icy surface is intricately carved by ongoing geological processes. Its icy shell overlies an internal, liquid ocean. There, chemically charged warm water seeps out of the rocky core.....»»
Nanoparticles deliver small interfering RNA to slow multiple myeloma
Research led by the University of Pennsylvania, Philadelphia, has used siRNA-based silencing of protein cyclophilin A (CyPA) to reduce tumor burden and extend the lives of patients with multiple myeloma......»»
Microneedle array embedded with ultrasound-triggered antibacterial nanoparticles for acne treatment
A research team led by Professor Kelvin Yeung from the Department of Orthopedics and Traumatology, School of Clinical Medicine, LKS Faculty of Medicine, the University of Hong Kong (HKUMed) has designed a new microneedle patch to offer a highly-effec.....»»
Using liquid metals to synthesize high-entropy alloy nanoparticles
A team of chemists and engineers affiliated with a large number of institutions in China has found that using liquid metal to synthesize high-entropy alloy nanoparticles (HEA-NPs) is a viable alternative to conventional methods. In their study, repor.....»»
The life below our feet: Team discovers microbes thriving in groundwater and producing oxygen in the dark
Nearly a third of Earth's freshwater resources lie in groundwater—much more than in all lakes, rivers and the atmosphere combined, and exceeded only by the frozen water in polar ice caps. Accordingly, about half of humankind depends on groundwater.....»»

Retooling the ribosomal translation machine could expand chemical repertoire of cells
Synthetic biologists have become increasingly creative in engineering yeast or bacteria to churn out useful chemicals—from fuels to fabrics and drugs—beyond the normal repertoire of microbes......»»
Team uncovers plant remediation effects on petroleum contamination
Initial choices about fertilization and grass seeding could have a long-lasting effect on how plants and their associated microbes break down pollution in petroleum-contaminated soils, a research team led by a University of Alaska Fairbanks professor.....»»
New study traces amino acids synthesized by gut microbes in wild animals
The role of the gut microbiome in our health has become an important topic in recent years, but a new study out of The University of New Mexico is the first of its kind to look at how it supports animals in the wild who are dealing with variable food.....»»
Study describes the melting of gold nanoparticles in gold-bearing fluids in the Earth"s crust
Gold is a precious metal that has always fascinated humans. From Priam's Treasure to the legend of El Dorado, gold—regarded as the noblest of metals—has been a symbol of splendor and wealth in many civilizations. Historically, gold deposits were.....»»
Nanoparticle therapy targeting specific immune cells appears promising for sepsis
Nanoparticles consisting of a designer protein that counteract an overreaction of the immune system, while simultaneously boosting that system. This invention offers possibilities for the treatment of sepsis, a condition in which the immune system is.....»»
Testing antibacterial surfaces on the International Space Station
Humans breathe out a lot of microbes that can make homes on surfaces inside the ISS. Enlarge / Because particles that astronauts breathe out can drift for a while before settling, most surfaces in the International Space Station.....»»
Cell-membrane coated nanoparticles light up two cancer biomarkers at once to give more complete picture of tumor
