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......»»
Human body is a breeding ground for antimicrobial resistance genes, shows new study
The community of microbes living in and on our bodies may be acting as a reservoir for antibiotic resistance, according to new research from the Earlham Institute and Quadram Institute in Norwich. The work is published in the journal Nature Communica.....»»

How a polymeric nanoparticle gene delivery system can promote bone formation
Does a "magic bullet" exist in regenerative medicine? Researchers have long wished to design a cutting-edge gene therapy that regenerates tissues damaged by disease or trauma. That wish may come true now that a research team has developed a polymeric.....»»
Boosting survival of a beneficial bacterium in the human gut
The microbes that inhabit the gut are critical for human health, and understanding the factors that encourage the growth of beneficial bacterial species—known as "good" bacteria—in the gut may enable medical interventions that promote gut and ove.....»»
Antibody fragment-nanoparticle therapeutic eradicates gastric cancer, shows research
A novel cancer therapeutic, combining antibody fragments with molecularly engineered nanoparticles, permanently eradicated gastric cancer in treated mice, a multi-institutional team of researchers found......»»
Fluidizing the cell membrane: Effective internalization of lipid nanoparticles for photodynamic cancer therapy
In order to deliver cancer therapeutics to tumor cells, the cells' membranes must be overcome. A team of researchers have discovered a simple way to achieve this using lipid nanoparticles containing the reagent EDTA (ethylenediaminetetraacetic acid)......»»
Humans are leaving behind a "frozen signature" of microbes on Mount Everest
Almost 5 miles above sea level in the Himalayan mountains, the rocky dip between Mount Everest and its sister peak, Lhotse, lies windswept, free of snow. It is here at the South Col where hundreds of adventurers pitch their final camp each year befor.....»»
As Millions of Solar Panels Age Out, Recyclers Hope to Cash In
Photovoltaic panels contain valuable metals, including silver and copper—but the supply of expired panels may overwhelm the capacity to process them......»»
Microbes can create a more peaceful world: Scientists issue call to action
Microorganisms should be 'weaponized' to stave off conflicts across the globe, according to a team of eminent microbiologists......»»
These juvenile snapping shrimp have the fastest claws in the sea
They can snap their claws at accelerations on par with a bullet shot from a gun. Juvenile snapping shrimp now hold the acceleration record for a repeatable body movement underwater. They can snap their claws at accelerations on par w.....»»
Light-to-energy conversion in many aquatic microbes more complex than was previously known, researchers discover
Plants convert light into a form of energy that they can use—a molecule called adenosine triphosphate (ATP)—through photosynthesis. This is a complex process that also produces sugar, which the plant can use for energy later, and oxygen. Some bac.....»»
COVID-19 lockdowns "turned India greener"
India's drastic COVID-19 lockdowns had a silver lining. With polluting industries and vehicular movement halted, urban dwellers were treated to bright, blue skies and views of snow-clad Himalayan peaks, long obscured by thick smog......»»
Scientists develop novel approach to enhance drug delivery for treatment of brain tumors in children
Mount Sinai Health System and Memorial Sloan Kettering Cancer Center researchers have developed a new drug delivery approach that uses nanoparticles to enable more effective and targeted delivery of anti-cancer drugs to treat brain tumors in children.....»»
Young snapping shrimps" tiny claws accelerate in water like a bullet
When it comes to a quick draw, few creatures outgun adult snapping shrimp (Alpheus heterochaelis). They stun passing fish and foes with a simple click of a spring-loaded claw, which squirts a high-speed jet that rips through the water, producing a va.....»»
Study elucidates effects of silver nanoparticles on inorganic carbon utilization of submerged macrophytes
Submerged macrophytes grow underwater and represent a group of higher plants adapted to the aquatic environments. As they grow in water, the uptake of inorganic carbon is very different from that of terrestrial plants. However, the diversity and abun.....»»
Nanoparticles self-assemble to harvest solar energy
Solar-thermal technology is a promising, environmentally friendly energy harvesting method with a potential role to play in solving the fossil fuel energy crisis......»»
Microbes may play a key role in unleashing "forever chemicals" from recycled-waste fertilizer
"Forever chemicals" are everywhere—water, soil, crops, animals, the blood of 97% of Americans—researchers from Drexel University's College of Engineering are trying to figure out how they got there. Their recent findings suggest that the microbes.....»»
Detecting rapidly mutating bacteria and viruses with AutoPLP
As we now know from our experience with the COVID-19 pandemic, the microbes responsible for some infections can rapidly mutate into variants that evade detection and treatment......»»
New hope for forests of ancient Athens" silver hills
It was once the source of Athens' fabulous golden-age wealth before its hillsides were blackened by fire after fire and scandalously torched by a foreign mining company......»»
How to see without eyes or a protein that senses light
Centipedes avoid light by registering the temperature changes it induces. Enlarge (credit: Kriswanto Ginting) Light-sensing proteins are found throughout all domains of life. Even single-celled microbes carry proteins th.....»»
