Nature’s Smallest Rainbows, Produced by Peacock Spiders, May Inspire New Optical Technologies
One species of peacock spider – the rainbow peacock spider (Maratus robinsoni) – is particularly impressive, because it showcases an intense rainbow iridescent signal in males’ courtship displays to females. This is the first known instance in nature of males using an entire rainbow of colors to entice females to mate. But how do males make their rainbows? A new study published in Nature Communications looked to answer that question.
Nanotubes go with the flow to penetrate brain tissue
Rice University researchers have invented a device that uses fast-moving fluids to insert flexible, conductive carbon nanotube fibers into the brain, where they can help record the actions of neurons. The Rice team’s microfluidics-based technique promises to improve therapies that rely on electrodes to sense neuronal signals and trigger actions in patients with epilepsy and other conditions.

Researchers Develop Test That Can Diagnose Two Cancer Types
A blood test using infrared spectroscopy can be used to diagnose two types of cancer, lymphoma and melanoma, according to a study led by Georgia State University. http://news.gsu.edu/2017/12/12/researchers-develop-blood-test-can-diagnose-two-types-cancer/
Group maps atomic shifts in charge-ordered manganite
Using a manganite crystal, a group led by Lena Kourkoutis, assistant professor of applied and engineering physics, has described a new approach to characterizing and understanding exotic charge-ordered phases in which electrons are ordered into periodic patterns. These phases are marked by ever-so-slight displacements (shifts) in the arrangement of a material’s atomic lattice and directly determine the properties of a material. http://news.cornell.edu/stories/2017/12/group-maps-atomic-shifts-charge-ordered-manganite
Seeing Through Walls of Unknown Materials
Researchers at Duke Engineering have developed a new way to see through walls using microwaves— without needing to know what the wall is made out of beforehand. According to the researchers, the new approach could lead to applications in security and devices to help locate conduits, pipes and wires. https://pratt.duke.edu/news/wall-scan

Optoelectronics origami: An easy-to-make, double-duty curved image sensor
In a breakthrough that could, for example, lead to cameras with beyond-the-state-of-the-art features such as infinite depth of field, wider view angle, low aberrations, and vastly increased pixel density, flexible optoelectronics pioneer Zhenqiang (Jack) Ma has devised a method for making curved digital image sensors in shapes that mimic an insect’s compound eye (convex) and a mammal’s “pin-hole” eye (concave).
