Scientists Decode Molecular and 3D Structure of Spiegelmers

Using DESY's ultra bright X-ray source PETRA III, scientists have decoded the molecular and three-dimensional structure of two promising drug candidates from the new group of Spiegelmers for the first time. The results provide a deeper understanding of the mode of action of these substances that have already entered clinical trials. The researchers from the Universities of Hamburg and Aarhus (Denmark) together with colleagues from the biotech company NOXXON in Berlin present their work in the journal Nature Communications.

Researchers Discover Efficient Terahertz Emission from 2D Arrays of Gold Split-Ring Resonator Metamaterials

The Science
Metamaterials allow design and use of light-matter interactions at a fundamental level. An efficient terahertz emission from two-dimensional arrays of gold split-ring resonator metamaterials was discovered as a result of excitation by a near-infrared pulsed laser.

Novel Device Measures Terahertz Waves with Extreme Precision

Light can come in many frequencies, only a small fraction of which can be seen by humans. Between the invisible low-frequency radio waves used by cell phones and the high frequencies associated with infrared light lies a fairly wide swath of the electromagnetic spectrum occupied by what are called terahertz, or sometimes submillimeter, waves. Exploitation of these waves could lead to many new applications in fields ranging from medical imaging to astronomy, but terahertz waves have proven tricky to produce and study in the laboratory.

Irregularity of Nanopillars Contributes to Low Reflection of Butterfly Wings

The effect is known from the smart phone: Sun is reflected by the display and hardly anything can be seen. In contrast to this, the glasswing butterfly hardly reflects any light in spite of its transparent wings. As a result, it is difficult for predatory birds to track the butterfly during the flight. Researchers of KIT under the direction of Hendrik Hölscher found that irregular nanostructures on the surface of the butterfly wing cause the low reflection. In theoretical experiments, they succeeded in reproducing the effect that opens up fascinating application options, e.g. for displays of mobile phones or laptops.

Dopamine Packaged in Biodegradable Nanoparticles Reverses Parkinson's-Like Symptoms

As baby boomers age, the number of people diagnosed with Parkinson's disease is expected to increase. Patients who develop this disease usually start experiencing symptoms around age 60 or older. Currently, there's no cure, but scientists are reporting a novel approach that reversed Parkinson's-like symptoms in rats. Their results, published in the journal ACS Nano, could one day lead to a new therapy for human patients.

Constant Angle of Curvature Enables Stability of Nanobubbles

It was a question that has kept physicists and chemists busy for more than twenty years. Why can tiny bubbles in a liquid supersaturated with gas remain stable for weeks, while according to theoretical expectation they should disappear in a fraction of a second? Prof. dr. ir. Detlef Lohse from the University of Twente's MESA+ research institute found the answer. The research was recently published in the scientific journal Physical Review E (Rapid Communication).

Anomalous Light-Like Behavior Now Realized in 3D Bulk Material

Electrons were observed to travel in a solid at an unusually high velocity, which remained the same independent of the electron energy. This anomalous light-like behavior is found in special two-dimensional materials, such as graphene, but is now realized in a three-dimensional bulk material. High-resolution angle-resolved electron spectroscopy, stimulated by synchrotron x-ray radiation, was used to substantiate the theoretically predicted exotic electron structure.
