People with certain health conditions that make them moderately or severely immunocompromised may get a fourth mRNA Covid-19 shot, according to updated guidelines from the US Centers for Disease Control and Prevention.
Moderately to severely immunocompromised people include those who are in active cancer treatment for cancers of the blood or for tumors, certain organ transplant and stem cell recipients, people with advanced or untreated HIV, and those who take a high-dose corticosteroids or other drugs that may suppress their immune systems. The CDC estimates about 9 million people who live in the US, or about 2% of the population, fall into this category.
Although skin aging has not been related to many health complications, it has aesthetic issues. Some of the common symptoms of skin aging are changes in the skin texture (rough, dry, and itchy), discoloration, [...]
In an article published in the journal Science of the Total Environment, researchers have highlighted the significance and potential risks associated with the release of nanoparticles from coal-fired power plants. Applying the single-particle inductively coupled plasma mass [...]
A paper recently published in the journal ACS Applied Energy Materials demonstrated the feasibility of using a covalent organic framework (COF)-based nanofluidic hybrid membranes (NHMs) to attain enhanced interfacial ion transport for the generation of osmotic [...]
The excess fluoroquinolones (FQs) discharged into the aquatic environment due to human activities must be removed cost-effectively. In an article published in the Journal of Cleaner Production, the authors fabricated an environment-friendly dealkaline lignin-grafted Fe3O4 nanoparticles [...]
Controlling strong electromagnetic fields on nanoparticles is the key to triggering targeted molecular reactions on their surfaces. Such control over strong fields is achieved via laser light. Although laser-induced formation and breaking of molecular [...]
A paper recently published in the journal Nature Communications demonstrated an effective method to realize on-chip nanophotonic topological rainbow devices using the concept of synthetic dimensions. Importance of Synthetic Dimensions for the Construction of Topological Nanophotonics [...]
In a study available in the journal Materials Today: Proceedings, silver nanoparticles (Ag NPs) were fabricated using a green method using Citrus X sinensis. Methylthioninium Chloride (MB) Dyes Threatening the Environment Dye and sewage drainage into [...]
Public health experts are divided over how many people are getting long COVID-19, a potentially debilitating condition that comes after a patient has recovered from the coronavirus. Ill effects from the condition can include [...]
Well over two years into the pandemic, hundreds of thousands of COVID cases continue to be recorded around the world every day. With the rise of new variants, the symptoms of COVID have also evolved. Initially, [...]
Drug resistance is a common phenomenon, with drugs becoming less and less effective as their usage increases. To address this issue, a novel technique employing conjugated polymer-based nanoparticles is presented in the study published [...]
Microrobots have the potential to revolutionize medicine. Researchers at the Max Planck ETH Centre for Learning Systems have now developed an imaging technique that for the first time recognises cell-sized microrobots individually and at [...]
Scientists have recently developed multifunctional hexagonal NaxWO3 nanocrystals that can serve as microwave sensitizers to kill cancer cells as well as improve the overall chemodynamic therapy (CDT). This study is available as a pre-proof in Chemical Engineering Journal. [...]
Apple’s visionary founder, the late Steve Jobs once said, “the biggest innovations of the 21st century will be at the intersection of biology and technology”. And that prediction is coming true in the drug [...]
Chemical separation processes are essential in the manufacturing of many products from gasoline to whiskey. Such processes are energetically costly, accounting for approximately 10–15 percent of global energy consumption. In particular, the use of [...]
