    New Radiotracer offers opportunities for Earlier Intervention after Heart Attack

     Binding specificity test. (A) PET/CT axial views, autoradiographs, and corresponding H&E stainings of 10-micron cross-sections prepared from MI nonblocked, blocked, and sham-operated rats. Autoradiographs and H&E stainings from nonblocked hearts show increased Ga-68-FAPI-04 uptake in infarcted area at 7 days after MI, whereas uptake is negligible after sham operation or injection of nonlabeled FAPI-04 (blocked). Infarcted areas in H&E stainings are identified with arrows. (B) PET image–derived infarct-to-noninfarct uptake ratio (derived from 6 nonblocked and 3 blocked rat hearts subjected to coronary ligation). (C) Autoradiography image–derived infarct-to-noninfarct uptake ratio (derived from 3 nonblocked and 3 blocked MI hearts). QL = quantum level.

    Imagine having access to a battery, which has the potential to power your phone for five continuous days, or enable an electric vehicle to drive more than 1000km without needing to “refuel”.

    Monash University researchers are on the brink of commercialising the world’s most efficient lithium-sulphur (Li-S) battery, which could outperform current market leaders by more than 4X, and power Australia and other global markets well into the future.

    Scientists find evidence that Venus has Active Volcanoes

    This figure shows the volcanic peak Idunn Mons (at 46 degrees south latitude, 214.5 degrees east longitude) in the Imdr Regio area of Venus. The colored overlay shows the heat patterns derived from surface brightness data collected by the Visible and Infrared Thermal Imaging Spectrometer (VIRTIS), aboard the European Space Agency's Venus Express spacecraft.

    New research led by Universities Space Research Association (USRA) and published today in Science Advances shows that lava flows on Venus may be only a few years old, suggesting that Venus could be volcanically active today—making it the only planet in our solar system, other than Earth, with recent eruptions.

    “If Venus is indeed active today, it would make a great place to visit to better understand the in...

    Alzheimer ‘Tau’ protein far surpasses Amyloid in predicting toll on brain tissue

    January 4, 2020, Categories  Health/Medical, Biology/Biotechnology

    Brain MRI scans
    Tau PET brain scans (green) in early clinical-stage Alzheimer’s patients accurately predict the location of brain atrophy measured by MRI 1–2 years later (magenta). Amyloid PET imaging (blue) does not predict the location of either tau or future brain atrophy.

    Tau PET brain imaging could launch precision medicine era for Alzheimer’s disease. Brain imaging of pathological tau-protein “tangles” reliably predicts the location of future brain atrophy in Alzheimer’s patients a year or more in advance, according to a new study by scientists at the UC San Francisco Memory and Aging Center...
