While scientists have been learning more and more about our solar system and the way things work, many of our Sun's mechanics still remain a mystery. In advance of the launch of the Parker Solar Probe, which will make contact with the Sun's outer atmosphere, however, scientists are foreshadowing what the spacecraft might see with new discoveries. In a paper published this week in The Astrophysical Journal, scientists detected structures within the Sun's corona, thanks to advanced image processing techniques and algorithms. The question that this group of scientists, led by Craig DeForest from the Southwest Research Institute's branch in Boulder, Colorado, was trying to answer was in regard to the source of solar wind. "In deep space, the solar wind is turbulent and gusty," said DeForest in a release.

When someone smokes cannabis, molecules including Tetrahydrocannabinol (THC), marijuana's main psychoactive ingredient, bind to a receptor in their brain. It is the interaction between the drug and this receptor, called CB1, that makes people feel high after smoking marijuana. Now researchers have published the clearest picture yet of this receptor - and it could help lead the way for the development of safe cannabis-based medicines. This image shows a the clearest image yet of a cannabinoid receptor, called CB1. The receptor is the yellow, ribbon-like structure.
Astronomers have released stunning high-resolution images showing the disks of dust and gas swirling around 20 young stars outside of our solar system. In a first of its kind survey, an international team used the Atacama Large Millimeter/ millimeter Array (ALMA) telescope in Chile for a large-sample investigation of these distant protoplanetary disks. The study has revealed new insight on the potential abundance of Neptune- or Jupiter-sized young planets in other corners of the Milky Way, and suggests our solar system may not be entirely unique. Researchers at the University of Nevada, Las Vegas say the 20 nearby protoplanetary disks observed in the study suggest there may be a greater number of large, young planets in our galaxy that previously expected. These have been left undetected due to the limitations of most planet-searching techniques used today.
A new form of high-resolution "printing" that could be developed for anti-counterfeiting measures in banknotes has been discovered by scientists from the University of Glasgow, Scotland. The team of engineers developed nanoscale plasmonic colour filters that display different colours depending on the orientation of the light that hits it. According to the university, the nanoscale printing breakthrough could also have implications for data storage and digital imaging as the new technique allows the "printing" of two entirely different, but exceptionally detailed, full-colour images within the same surface area. The team demonstrated their technique with several examples, including a nanoscale image that shows the university's crest when the light reaches it in one orientation, and an image of the university tower when the orientation of the light is reversed. "We've discovered that if we make colour pixels from tiny cross-shaped indents on a strip of aluminium film, the colour they display becomes polarisation-dependent, allowing us to encode two colours into a single pixel, and then select which colour is displayed by shining different polarisations of light at the surface," said biomedical engineering lecturer Dr Alasdair Clark, lead author of the research paper.
