    World’s Fastest Optical Neuromorphic Processor

    January 9, 2021, Categories  Health/Medical, Biology/Biotechnology

    Dr Xingyuan (Mike) Xu with the integrated optical microcomb chip, which forms the core part of the optical neuromorphic processor.

    An international team of researchers led by Swinburne University of Technology has demonstrated the world’s fastest and most powerful optical neuromorphic processor for artificial intelligence (AI), which operates faster than 10 trillion operations per second (TeraOPs/s) and is capable of processing ultra-large scale data.

    Published in the journal Nature, this breakthrough represents an enormous leap forward for neural networks and neuromorphic processing in general.

    Artificial neural networks, a key form of AI, can ‘learn’ and perform complex operations with wide applications to computer vision, natural language processing, facial recognition, speech...

    Striped or spotted? Winds and Jet Streams found on the closest Brown Dwarf

    January 9, 2021, Categories  Astronomy/Space

    Using high-precision brightness measurements from NASA’s TESS space telescope, astronomers found that the nearby brown dwarf Luhman 16B’s atmosphere is dominated by high-speed, global winds akin to Earth’s jet stream system. This global circulation determines how clouds are distributed in the brown dwarf’s atmosphere, giving it a striped appearance.Daniel Apai

    A University of Arizona-led research team has found bands and stripes on the brown dwarf closest to Earth, hinting at the processes churning the brown dwarf’s atmosphere from within.

    Brown dwarfs are mysterious celestial objects that are not quite stars and not quite planets. They are about the size of Jupiter but typically dozens of times more massive...

    New Drug Form may help treat Osteoporosis, Calcium-related Disorders

    January 8, 2021, Categories  Health/Medical, Biology/Biotechnology

    Elizabeth Topp, a Purdue professor of physical and industrial pharmacy, helped develop a stabilized form of human calcitonin, which is a peptide drug already used for people with osteoporosis.

    A novel form of a drug used to treat osteoporosis that comes with the potential for fewer side effects may provide a new option for patients. The work is supported by the National Institutes of Hqealth and is published in Biophysical Journal.

    Purdue University innovators developed a stabilized form of human calcitonin, which is a peptide drug already used for people with osteoporosis. Researchers at Purdue created a prodrug form of the peptide hormone to increase its effectiveness as an osteoporosis treatment.

    In humans, calcitonin is the hormone responsible for normal calcium homeostasis...

    Conductive ink is a great tool for printing flexible electronic circuits on surfaces. But these inks can be costly, they do not work on some materials, and devices to apply them can plug up. Now, scientists report in ACS Applied Electronic Materials that they have developed inexpensive conductive inks for clog-free ballpoint pens that can allow users to “write” circuits almost anywhere — even on human skin.

    Flexible electronics are widely used in applications such as biosensors, electronic skin and energy storage...
