    Quorn Protein Builds Muscle Better than Milk Protein

    Mycoprotein is unique to Quorn products

    A study from the University of Exeter has found that mycoprotein, the protein-rich food source that is unique to Quorn products, stimulates post-exercise muscle building to a greater extent than milk protein.

    The study evaluated the digestion of protein, which allows amino acids (the building blocks of protein) to increase in the bloodstream and then become available for muscle protein building in 20 healthy, trained young men at rest and following a bout of strenuous resistance exercise.

    The young men performed the exercise and were then given either milk protein or mycoprotein. Their muscle building rates were then measured using stable isotope labelled “tracers” in the hours following protein consumption.

    Animal proteins like milk are an exce...

    Molecular Thumb Drives: Researchers store Digital Images in Metabolite Molecules

    The approach maps the ones the zeros of digital data to the presence or absence of particular molecules in solutions. The researchers used the scheme to encode image files in solutions.

    In a step toward molecular storage systems that could hold vast amounts of data in tiny spaces, researchers have shown it’s possible to store image files in solutions of common biological small molecules.

    DNA molecules are well known as carriers of huge amounts of biological information, and there is growing interest in using DNA in engineered data storage devices that can hold vastly more data than our current hard drives. But new research shows that DNA isn’t the only game in town when it comes to molecular data storage.

    A study led by Brown University researchers shows that it’s possible to s...

    HIV Eliminated from the Genomes of Living Animals

    July 5, 2019, Categories  Biology/Biotechnology, Health/Medical

    A working model for HIV-1 elimination. A cartoon illustration of the viral elimination strategy is shown for single LASER ART, AAV9-CRISPR-Cas9 injection groups and dual treatment groups. We highlight the observed restriction of viral infection by LASER ART and an inability to achieve elimination of virus by AAV9-CRISPR-Cas9 treatment alone. However, the sequential administration of LASER ART and AAV9-CRISPR-Cas9 can achieve viral elimination in a subset of animals. Why specific animals are cured of infection while others are not is incompletely understood but tied, in measure, to viral set points

    Researchers have for the first time eliminated replication-competent HIV-1 DNA – the virus responsible for AIDS – from the genomes of living animals...

    Machine enhanced humans – or cyborgs as they are known in science fiction – could be one step closer to becoming a reality, thanks to new research Lieber Group at Harvard University, as well as scientists from University of Surrey and Yonsei University.

    Researchers have conquered the monumental task of manufacturing scalable nanoprobe arrays small enough to record the inner workings of human cardiac cells and primary neurons.

    The ability to read electrical activities from cells is the foundation of many biomedical procedures, such as ...
