W8405-1R: A Red Skin White Flesh Potato for the Fresh Market

UW–Madison researchers have developed W8405-1R, a red potato variety with very smooth and uniform tubers, round-oval shape, shallow eyes and attractive coloring that maintains well in storage.

The new variety is available through the Wisconsin Crop Improvement Association.

Platform for High-Throughput Analysis of Microbial Interactions

UW–Madison researchers have developed a research tool for large-scale mapping of interactions in microbiomes. Their method employs gene sequencing in a microfluidic system to increase throughput by several orders of magnitude (1,000-10,000 times).

Specifically, the researchers mixed groups of several species of bacteria in culture. They encapsulated cells into millions of picoliter droplets dispersed in an oil phase. The droplets were incubated to allow the microbes to interact, assemble into a community and perform functional activities. After incubation, the composition of the community within the droplet was analyzed using fluorescence microscopy or next-generation DNA sequencing.

The presence or absence of microbes in a drop can be indicative of different species preferentially interacting with other species in the bulk culture or droplet, and can be used to reconstruct the microbiome’s ecological network.

Semiconductor Quantum Dot Computer-Aided Engineering (CAE) Simulation Tool

A Professor of Electrical Engineering at the University of Wisconsin – Platteville has developed a software simulation tool for the computer aided engineering (CAE) of Quantum Dots. The CAE simulation tool accepts input of the QD parameters and then computes and returns the resulting optical and electronic properties. This includes QD structures with an InAs core and a GaAs matrix, and can be extended to any III-IV materials. The CAE tool simulates the most popular pyramidal and half-ellipsoidal QD shapes and can be extended to any arbitrary geometric shape. Compared with the often-incomplete results reported in the literature, this CAE simulation tool returns all possible electronic states within the QD. The CAE simulation results also supported the experimental data for the corresponding QD. The simulation tool currently runs as an application in the COMSOL platform and does not require a supercomputer for calculations and processing.

Novel Catalysts for Improved Remediation of Sulfur-Containing Pollutants

A professor of chemistry at the University of Wisconsin-La Crosse has developed a versatile suite of iron-based catalysts with the potential to promote rapid, efficient oxidation of deleterious sulfur-containing compounds present in crude oil, natural gas, and/or aqueous waste streams. With these novel catalysts, there is no need for corrosive base, elevated temperatures, expensive or dangerous oxidants, or high pressures.

App for Stratifying Autism Spectrum Disorders

UW–Madison researchers have developed a software test to differentiate ASD participants into two distinct types of contextual learners. The first group resembles a “Typically Developing” (TD) learning profile, and the second group does not modulate with context, indicating that they are not able to learn the embedded context.

Participants viewed a monitor divided into four quadrants and were asked to search for a visual target, then indicate the quadrant in which the target was located. Unbeknownst to the participants, contextual information about the target location was manipulated across sessions by varying the number of off-targets and the probability of the target being present in that quadrant. Search time as a function of the proportion of informative cues in the target quadrant was used as a measure of contextual learning.

New Technology for Measuring Stress in Tendons, Ligaments and Muscles

UW–Madison researchers have developed a new device and technique for dynamically, noninvasively and accurately measuring longitudinal stress in tendons, muscles and ligaments in vivo.

The inventors use skin-mounted accelerometers to measure transverse wave speeds in superficial tissues under time-varying loading scenarios. Such wave speed propagation metrics are then used to determine tissue stress based on a wave propagation model.

Field Portable Smartphone Device for Water Quality Monitoring

A University of Wisconsin-Green Bay professor of chemistry has developed a portable, accurate, low cost, smartphone-based analytical device for the field-measurement and geographical mapping of environmentally relevant water quality parameters. In its current embodiment, the device is a colorimeter for measuring absorbance that includes a visible light source with onboard power, imaging filters, a sample cuvette, and a mounting mechanism for attachment to a smartphone or tablet. An accompanying app is used to record camera images of samples and convert them to numerical absorbance data for analysis. The app will be further developed to allow integration with an online ArcGIS platform for uploading and mapping the data.

Enhanced Blood-Brain Barrier Model Outperforms All Others

UW–Madison researchers have developed a more realistic, reproducible in vitro model of the BBB. The model uses either human embryonic or induced pluripotent stem cells as a source of BMECs.

These cells are treated with retinoic acid to produce further BBB maturation and improve barrier properties. They are purified and co-cultured with other types of neurovascular cells, including pericytes, astrocytes and differentiated neural progenitor cells (NPCs).
