Microbiology and Life Science News

Microplastics are everywhere. Scientists have found them in the deepest ocean trenches, in Arctic ice, in agricultural soils, in drinking water, and increasingly, inside the human body itself. Researchers have identified microplastic particles in human blood, liver tissue, and even brain samples. Yet despite their ubiquity, one fundamental question has remained stubbornly difficult to answer: what exactly happens to these particles once they enter a living organism?

What if the water flowing beneath our cities could tell us how healthy our communities really are?

Maintaining low particle counts is critical in the process of packaging pharmaceuticals, particularly for liquid products that must meet strict sterility and cleanliness requirements, as particulate contamination can be introduced from raw materials, processing equipment, tubing connections, and the surrounding environment. Without effective control, these particles can compromise product quality, process consistency, and regulatory compliance.  

Seattle’s biotechnology scene is making global headlines, producing three Nobel Prize winners in just two years — a reflection of the region’s growing influence in scientific innovation.  

Collecting and transporting biological samples in the field can be challenging. Traditional methods often require cold storage, centrifugation, and liquid handling; tools not always available in remote or harsh environments. Nobuto blood filter strips offer a simple, portable, and reliable solution for collecting, drying, and transporting blood or serum samples without a cold chain [1].

Soils associated with industrial operations such as landfills, manufacturing facilities, and the intensive use of agricultural chemicals can be prone to heavy metal accumulation.  Toxic heavy metals such as lead, arsenic, cadmium, and mercury can accumulate in soil, where they are absorbed by crops and plants. As a result, consumption of these crops inevitably leads to heavy metal exposure¹.

In biomedical research, extracellular vesicles (EVs)—especially exosomes—have become a key focus due to their role in intercellular communication. These nano-sized lipid-bilayer vesicles (30–150 nm), secreted by nearly all cell types, transport proteins, lipids, and nucleic acids, positioning them as valuable tools for diagnostics and therapeutics. However, their small size and low abundance in biological fluids make conventional methods for isolation and purification challenging.  Ultracentrifugation is labor-intensive, costly, and can damage exosome structure under high centrifugal forces, while precipitation and size-exclusion chromatography often produce low-purity samples contaminated with proteins and other non-exosomal particles. 

As mRNA-based vaccines and therapies continue to proliferate, the downstream purification process, particularly Tangential Flow Filtration (TFF), has become a critical efficiency and cost focus. Yet, data on optimizing TFF for mRNA is notably scarce, complicating process development. 

As air pollution continues to pose significant threats to public health and the environment, the demand for accurate and efficient air quality monitoring has never been more urgent. Among various pollutants, PM2.5, which are fine particulate matter with a diameter of 2.5 micrometers or less, stands out due to its ability to penetrate deep into the respiratory system and bloodstream, contributing to a wide range of health issues. 

August 26 is National Dog Day, a perfect moment to celebrate the dogs we love—and protect their health with proactive care. One critical but often overlooked step in safeguarding your dog from disease is routine testing for heartworm.
