One important aspect of biodiversity is genetic variation within species. A notable example is the variety of cultivars of crop plants. Scientists have now characterized at the molecular level a world collection of barley, comprising seed samples from more than 22,000 varieties. from Latest Science News -- ScienceDaily https://ift.tt/2Pv1BjV

Scientists have succeeded in significantly increasing the stability and biocompatibility of special light-transducing nanoparticles. They have developed so-called ''upconverting'' nanoparticles that not only convert infrared light into UV-visible light, but also are water-soluble, remain stable in complex body fluids, and can be used to store medications. They have created a tool that could potentially make the fight against cancer more effective. from Latest Science News -- ScienceDaily https://ift.tt/2T9cIxf

As an indicator of the impacts of climate change, Arctic sea ice is hard to beat. Scientists have observed the frozen polar ocean advance and retreat at this most sensitive region of the Earth over decades for insight on the potential ripple effects on assorted natural systems: global ocean circulation, surrounding habitats and ecosystems, food sources, sea levels and more. from Latest Science News -- ScienceDaily https://ift.tt/2OFnmZ5

The cognitive skills of a future employee are examined during a job interview. However, qualifications and a nice character don't necessarily mean that the interviewee will be a competent colleague. The individual's emotional intelligence has to be factored in, that is, his capacity to understand, regulate and manage emotions in the specific context of the work environment. Researchers have now devised an emotional intelligence test that measures emotional competences at work. from Latest Science News -- ScienceDaily https://ift.tt/2zObK0D

Scientists have now characterized the higher energy levels reached by electrons in resonance in three-particle systems, which are too complex to be described using simple equations. This theoretical model is intended to offer guidance for experimentalists interested in observing these resonant structures in positronium ions. from Latest Science News -- ScienceDaily https://ift.tt/2z5NQ0L
