    Complementary logic circuits based on high-performance n-type organic electrochemical transistor. Researchers at the Laboratory of Organic Electronics, Linköping University, have developed the world’s first complementary electrochemical logic circuits that can function stably for long periods in water. This is a highly significant breakthrough in the development of bioelectronics.

    The first printable organic electrochemical transistors were presented by researchers at LiU as early as 2002, and research since then has progressed rapidly. Several organic electronic components, such as light-emitting diodes and electrochromic displays, are already commercially available.

    The dominating material used until now has been PEDOT:PSS, which is...

    Astronomers uncover Largest known Population of Brown Dwarfs sprinkled among Newborn stars in the Orion Nebula

    January 13, 2018, Categories  Astronomy/Space

    This image is part of a Hubble Space Telescope survey for low-mass stars, brown dwarfs, and planets in the Orion Nebula. Each symbol identifies a pair of objects, which can be seen in the symbol's center as a single dot of light. Special image processing techniques were used to separate the starlight into a pair of objects. The thicker inner circle represents the primary body, and the thinner outer circle indicates the companion. The circles are color-coded: red for a planet; orange for a brown dwarf; and yellow for a star. Located in the upper left corner is a planet-planet pair in the absence of a parent star. In the middle of the right side is a pair of brown dwarfs. The portion of the Orion Nebula measures roughly four by three light-years. Credit: NASA , ESA, and G. Strampelli (STScI)

    Astronomers using the Green Bank Telescope have made the first definitive interstellar detection of benzonitrile, an intriguing organic molecule that helps to chemically link simple carbon-based molecules and polycyclic aromatic hydrocarbons. This discovery is a vital clue in a 30-year-old mystery: identifying the source of a faint infrared glow that permeates the Milky Way and other galaxies.

    Astronomers had a mystery on their hands. No matter where they looked, from inside the Milky Way to distant galaxies, they observed a puzzling glow of infrared light...

    Immune cells that process food and bacterial antigens in the intestines control the intestinal population of fungi, according to a new study from Weill Cornell Medicine scientists. Defects in the fungus-fighting abilities of these cells may contribute to some cases of Crohn’s disease and other forms of inflammatory bowel disease (IBD).

    “After discovering that fungi might be involved in the pathology of IBD, one of the big questions in the field has been how to identify patients who would benefit from antifungal co-therapy, and our finding suggests a way to do that,” said Dr...
