The UO Physics research team, lead by Professor Richard Taylor, studied the potential performance of their bio-inspired implant, which would be inserted behind the eye’s retina. The implant features an array of fractal electrodes designed to stimulate retinal neurons.
In theory, fractal implants act much like a pixel array at the back of a camera. They use a lot of pixels within a confined space at the back of the eye, providing electrically-restored vision at a higher resolution, Watterson said. In retina-damaged eyes, the cones and rods that do such intermediate work disappear. The implants would replace them and stimulate the still-intact neurons.

Professor Graham Kribs research into dark matter highlighted in an Around-the-O article:
Defining dark matter isn’t easy. It is thought to be particles that can only feebly interact with the known particles of the universe. The particles, whatever they are, are tied to the expansion of the universe, beginning with the Big Bang.
Scientists have strong evidence from observations of the first light, when the universe became transparent to visible wavelengths of light. So far, however, the evidence has been revealed only through dark matter’s gravitational effects on galactic and larger scales.
Finding dark matter, Kribs said, is about advancing fundamental knowledge about the universe.

The UO team of ecologist and evolutionary biologist Brendan Bohannan, microbiologist Karen Guillemin and biophysicist Raghuveer Parthasarathy won out over nearly 100 applications from 17 countries.
The research team plans to develop tools that allow bacteria to report on their activities, such as a probe that lights up once a gene that enables motion is activated or when a bacterium is experiencing stress. The research builds on existing projects that all three researchers have been working on, including three-dimensional microscopy that examines the insides of zebrafish.
“It is this combination of molecular biology, biophysics, imaging and ecology that is particularly exciting, and I firmly believe it’s only through a combination like that that we’re going to actually learn something insightful about these systems,” Parthasarathy said.

“Your visual system is in some way hardwired to understand fractals,” said Taylor. “The stress-reduction is triggered by a physiological resonance that occurs when the fractal structure of the eye matches that of the fractal image being viewed.” If a scene is too complicated, like a city intersection, we can’t easily take it all in, and that in turn leads to some discomfort, even if subconsciously. It makes sense that our visual cortex would feel most at home among the most common natural features we evolved alongside. So perhaps part of our comfort in nature derives from fluent visual processing.

Stephanie Majewski likes it when things bump into each other.
Which is a huge OVER-simplification of her work in the field of physics at the University of Oregon.
But it IS true that she learns a lot from atoms crashing into each other, especially at the Large Hadron Collider (LHC) in Switzerland.
Dr. Majewski’s work is the topic of this month’s installment of “cUriOus: Research Meets Radio.”
We pick her brain about dark matter, supersymmetry, and more.
In Corwin’s lab, researchers created a simple large-scaled system in which the waves they generated represented molecules that would be present in a microscale material. What they did provided a scientific proof-of-concept that is detailed a paper published online ahead of print in the Proceedings of the National Academy of Sciences.
The research shows that the surface of water can be altered to form a two-dimensional metafluid with independent control of effective internal temperature, molecular movement and viscosity so that it takes on the quality of something else.

UO Physics Professor Raghuveer Parthasarathy’s Research on Bacterial Competition Featured in ‘Around the O’ Article
With help from 3-D microscopy, collaborating scientists from three labs discovered that bacterial competition in the zebrafish gut is driven by natural mechanical contractions that move contents through the intestine. Their findings are detailed in the July 26 issue of the online journal PLOS Biology. http://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.1002517
Numerous diseases are tied to gut microbiota. The probiotics industry targets intestinal health with products built mostly around enzyme cultures and bacteria. The UO discovery could lead to better products, said Raghuveer Parthasarathy, a professor of physics.
