    First observation of the Early Link between Proteins linked to Alzheimer’s disease

    January 27, 2021, Categories  Health/Medical, Biology/Biotechnology

    State-of-the-art automatic brainstem segmentation methods were used to extract tau burden in its first aggregation site, that is, in the brainstem monoaminergic grey matter (bmGM). Beta-amyloid (Aβ) burden was extracted in the earliest cortical aggregation regions, i.e. in the bilateral medial superior frontal, inferior temporal, and fusiform areas.

    Study conducted by researchers from the GIGA CRC In vivo Imaging laboratory at ULiège demonstrates, for the first time in humans, how the first deposits of tau proteins in the brainstem are associated with neurophysiological processes specific to the early stages of Alzheimer’s disease development.

    During the pre-clinical stages of Alzheimer’s disease, i.e...

    No more Needles for Diagnostic Tests?

    Nearly pain-free microneedle patch can test for antibodies and more in the fluid between cells. Medical researchers have developed a biosensing microneedle patch that can be applied to the skin, capture a biomarker of interest and, thanks to its unprecedented sensitivity, allow clinicians to detect its presence.

    Blood draws are no fun. They hurt. Veins can burst, or even roll — like they’re trying to avoid the needle, too...

    A unique six-planet system, 200 light years away from Earth, has been observed around the star TOI-178 by an international research team including scientists from the University of St Andrews.

    The observations were made using the CHEOPS (Characterising ExOPlanets Satellite) space telescope that was launched in December 2019 with the important goal of precisely measuring the size of known planets. However, as this work finds, the spacecraft has the exciting potential to discover new planets.

    CHEOPS is a joint mission by the European Space Agency (ESA) and Switzerland, under the aegis of the University of Bern in collaboration with the University of Geneva and the University of St Andrews.

    The team had believed there ...

    Magnetic Waves explain Mystery of Sun’s Outer Layer

    The Sun’s extremely hot outer layer, the corona, has a very different chemical composition from the cooler inner layers, but the reason for this has puzzled scientists for decades.

    One explanation is that, in the middle layer (the chromosphere), magnetic waves exert a force that separates the Sun’s plasma into different components, so that only the ion particles are transported into the corona, while leaving neutral particles behind (thus leading to a build-up of elements such as iron, silicon and magnesium in the outer atmosphere).

    Now, in a new study published in The Astrophysical Journal, researchers combined observations from a telescope in New Mexico, the United States, with satellites located near Earth to identify a link between magnetic waves in the chromosphere and area...
