    The research team say that their findings could also help pioneer the development of home-collection tests for bladder or kidney cancer.

    The research team say that their findings could also help pioneer the development of home-collection tests for bladder or kidney cancer.

    A simple urine test under development for prostate cancer detection can now use urine samples collected at home – according to new research from University of East Anglia and the Norfolk and Norwich University Hospital.

    Scientists pioneered the test which diagnoses aggressive prostate cancer and predicts whether patients will require treatment up to five years earlier than standard clinical methods.

    Their latest study shows how the ‘PUR’ test (Prostate Urine Risk) could be performed on samples collecte...

    a, Preparation of InP cores and InP/ZnSe/ZnS QDs with different morphology and shell thickness. The amounts of Se precursor for QD-1, QD-2 and QD-3 were 0.6 mmol, 1.2 mmol and 2.0 mmol, respectively, per 10 ml of solvent. The estimated size, based on inductively coupled plasma-atomic emission spectroscopy (ICP-AES) data, was projected on the STEM image of each QD. b, Ultraviolet–visible absorption spectra of the aliquots, taken during the InP core synthesis. a.u., arbitrary units. c, Photoluminescence spectra of QD-1′ (prepared without HF addition), QD-1, QD-2, QD-3, QD-1R, QD-2R and QD-3R. Inset, photograph of QD-1′ (no HF) and QD-3 taken under 365 nm illumination. d–i, STEM images of QD-1, QD-1R, QD-2, QD-2R, QD-3 and QD-3R (scale bar, 20 nm)...

    Mapping our Galaxy’s Magnetic Field

    December 2, 2019, Categories  Astronomy/Space

    A representation of how our Galaxy would look in the sky if we could see magnetic fields. The plane of the Galaxy runs horizontally through the middle, and the Galactic centre direction is the middle of the map. Red–pink colours show increasing Galactic magnetic field strengths where the direction is pointing towards the Earth. Blue–purple colours show increasing Galactic magnetic field strengths where the direction is pointing away from the Earth. The background shows the signal reconstructed using sources outside our Galaxy. The points show the current measurements for pulsars. The squares show the measurements from this work using LOFAR pulsar observations. Credit: Freshscience

    Astronomers from CSIRO and Curtin University have used pulsars to probe the Milky Way’s magnetic fie...

    First-of-a-kind Electro-Optical Device provides solution to faster and more energy efficient Computing Memories and processors

    December 2, 2019, Categories  Physics, Technology/Electronics

    The team has created a first-of-a-kind electro-optical device that bridges the fields of optical and electronic computing.

    The first ever integrated nanoscale device which can be programmed with either photons or electrons has been developed by scientists in Harish Bhaskaran’s Advanced Nanoscale Engineering research group at the University of Oxford.

    In collaboration with researchers at the universities of Münster and Exeter, scientists have created a first-of-a-kind electro-optical device which bridges the fields of optical and electronic computing. This provides an elegant solution to achieving faster and more energy efficient memories and processors.

    Computing at the speed of light has been an enticing but elusive prospect, but with this development it’s now in tangible pro...
