Pesticides, pharmaceutical products, and endocrine disruptors are some of the emerging contaminants often found in treated domestic wastewater, even after secondary treatment. Professor Patrick Drogui of the Institut national de la recherche scientifique (INRS) and his team have tested the effectiveness of a tertiary treatment process using electricity in partnership with the European Membrane Institute in Montpellier (IEM) and Université Paris-Est.
This is one of the first comprehensive looks at lung cells using a technology called single-cell RNA sequencing. Instead of examining a mash-up of many cells from a tissue sample, single-cell sequencing allowed researchers in this study to closely examine the individual cells that make up the lungs; to identify their function, and ultimately understand the molecular changes that may be driving the disease.
The discovery of green fluorescent protein (GFP), which is made by a jellyfish, transformed cell biology. It allowed scientists to stitch the GFP sequence to proteins from other organisms to trace their movements and interactions in living cells. Now, researchers reporting in ACS Applied Materials & Interfaces have designed peptide nanoparticles that can each glow in a variety of colors, opening the door for many new biomedical applications.
Early results from modeling and a feasibility study for fit testing suggest that the iMASC system, a N95mask alternative, could fit faces of different sizes and shapes and be sterilized for reuse.
A method to extract carbohydrates and phycobiliproteins from algae was developed that does not kill the algae during harvest or rely on solvents for extraction and purification. This novel method uses mechanical shearing to 'milk' the desired compounds, greatly reducing the production cost of algae-derived compounds.
Aortic valve stenosis is the most common type of heart valve disease in the elderly and affects more than one in eight people aged over 75. Researchers used organ-on-a-chip technology to discover the disease is made worse by the damaging hyperactivity of immune cells, which are activated by the constant stress of squeezing through the narrow aortic valve.
MIT engineers are using computing modeling to prevent microparticles from clogging during injections.
Researchers of the Hong Kong University of Science and Technology (HKUST) recently uncovered novel molecular mechanisms that regulate delivery of a planar cell polarity protein, Frizzled-6, to the cell surface. This finding provides important information to guide the rational design of inhibitors to downregulate planar cell polarity pathway for cancer treatment.
A research team in Japan reported that they succeeded in producing the spider silk -- ultra-lightweight, though, biodegradable and biocompatible material -- using photosynthetic bacteria. This study will open a new era in which bio-factories stably output the bulk of spider silk.
Researchers at Karolinska Institutet in Sweden have developed a new method that can make it easier for public authorities to assess the health risks of hormone-disrupting chemicals in the environment. The study, which is published in Environmental Health Perspectives, shows that women are particularly at risk of decreased levels of thyroid hormones related to PFAS-contaminated drinking water.
