The researchers tested the indicator with water from 13 river locations that had limited bioavailable phosphorus, calculating red-toblue fluorescence ratios with a smartphone’s color scanning app. They found that the portable digital method reliably detected alkaline phosphatase and was as robust as benchtop measurements of the indicator’s fluorescence. The researchers also grew toxinproducing cyanobacteria in the lab, feeding them complex phosphorus-containing compounds, and measured the alkaline phosphatase changes. On the third day, a large increase in enzyme activity was detected with both fluorescence and visible color changes. A few days later, the algae were growing exponentially. Because the indicator and smartphone-based system detected the activity surge prior to a bloom, the researchers say it could be developed for real-time field monitoring and prediction.

dies. In sensory tests, 120 untrained panelists gave the gummies high scores for taste, color, aroma and overall acceptability. About half of the panelists said they would buy the enriched gummy, with another 36% saying they might buy the product. The researchers say their results pave the way to make food products more nutritious.

From the Editor
Not much is going on in November (or December, usually), but meetings (virtual and in person) will pick up after the first of the year. However, there are several positions open at local universities, so give them a look-over if you are in the market. Plant-based gummies with all the right vitamins and NO animal products?...it doesn’t get any better than that. A report in ACS Applied Materials & Interfaces shows the reversal of new-onset type 1 diabetes in mice with pyramid-like DNA molecules called tetrahedral framework nucleic acids (tFNAs). Yunfeng Lin and colleagues researchers made tFNAs from four single-stranded DNA segments that self-assembled into pyramidlike shapes, called tetrahedrons. (….a pyramid is square at its base, tetrahedrons are triangular). The self-assembly is what truly fascinates me; what other molecules can be formed in this manner?
