New understanding of the evolution of cosmic electromagnetic fields
Electromagnetism was discovered 200 years ago, but the origin of the very large electromagnetic fields in the universe is still a mystery.

Dynamic pattern of Skyrmions observed
Tiny magnetic vortices known as skyrmions form in certain magnetic materials, such as Cu2OSeO3. These skyrmions can be controlled by low-level electrical currents — which could facilitate more energy-efficient data processing. Now a team has succeeded in developing a new technique at the VEKMAG station of BESSY II for precisely measuring these vortices and observing their three different predicted characteristic oscillation modes (Eigen modes).

Current testing for Lyme disease, called the standard 2-tiered approach or the STT, involves running two complex assays (ELISA and western blot) to detect antibodies against the bacterium, and requires experienced personnel in a lab, and a few hours to carry out and interpret. Biomedical engineers have developed a rapid microfluidic test that can detect Lyme disease with similar performance as the STT in a much shorter time — 15 minutes.

An international study has unveiled a detailed view of how thalidomide, one of the most notorious drugs ever developed, causes abnormalities in limb and ear development. The findings may contribute to the re-emergence of safe, or non-teratogenic, thalidomide-derived drugs as a treatment for cancer and inflammatory diseases.

Researchers have developed 3-dimensional human tissue culture models of pediatric and adult brain cancers in a brain-mimicking microenvironment, that includes brain-derived extracellular matrix (ECM) — the complex network of proteins and amino acids with bound sugars that not only provides support for surrounding neural tissue, but also helps to guide cell growth and development. The development represents a significant advancement for the study of brain tumor biology and pharmacological response.
Read moreExoplanets to medical tests: Tiny frequency devices open up new applications
Accurately measuring frequencies of light is required for timekeeping and many science experiments and technologies. Frequency combs, invented in 2000, are used to complete these measurements. However, most of them are large and cumbersome. In 2009, researchers developed a way to make much smaller combs, but they came with their own challenges. New research finds that a novel way of generating frequency combs could address these challenges, leading to compact frequency combs with untold applications.

Scientists have helped three amputees merge with their bionic prosthetic legs as they climb over various obstacles without having to look. The amputees report using and feeling their bionic leg as part of their own body, thanks to sensory feedback from the prosthetic leg that is delivered to nerves in the leg's stump.
