New Inventions

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.

Designing Programmable Inducible Promoters for Biosensor Applications

UW–Madison researchers have developed a method for de novo design of synthetic inducible promoters for transcription factors and other DNA binding proteins such as aTFs with tunable dynamic range behavior and compatibility with virtually any host organism.

The method can include selecting inducible promoters, for example, by converting a constitutive promoter of an organism into an inducible promoter by introducing binding sites near the RNA polymerase binding site. By controlling the access of a transcription factor and the RNA polymerase to the promoter, the dynamic range of the system can be controlled.

Genetic Testing for Acquired Peripheral Neuropathy in Dogs

UW–Madison researchers have identified a single nucleotide polymorphism (SNP) that is predictive of APN syndrome in dogs, based on a genome-wide association study. Using a population of Labrador retrievers (56 cases and 26 controls), the researchers have shown that a SNP on CFA1 tags the causal variant for APN in the Labrador retriever breed.

Improved System for Stroke Therapy and Rehabilitation

UW-Madison researchers have developed an improved system for stroke therapy and rehabilitation.  This system collects movement intention signals from the brain in real-time via EEG and initiates functional electrical stimulation (FES) of the appropriate muscle(s) to assist the neurons in regrowing their connections from the brain to the muscles along the correct pathways.  Additional general sensory stimulation may be added to this therapy to further encourage proper neuron regrowth.
