  • Nanocontainer ships titan-size gene therapies and drugs into cells
    on December 6, 2019 at 7:00 pm

    Scientists at Johns Hopkins Medicine report they have created a tiny, nanosize container that can slip inside cells and deliver protein-based medicines and gene therapies of any size—even hefty ones attached to the gene-editing tool called CRISPR. If their creation—constructed of a biodegradable polymer—passes more laboratory testing, it could offer a way to efficiently ferry larger medical compounds into specifically selected target cells.

  • Researchers add order to polymer gels
    on December 6, 2019 at 7:00 pm

    Gel-like materials have a wide range of applications, especially in chemistry and medicine. However, their usefulness is sometimes limited by their inherent random and disordered nature. Researchers from the University of Tokyo's Institute for Solid State Physics have found a way to produce a new kind of gel which overcomes this limitation. It is still malleable and adaptable like existing gels, but it has a more ordered structure, which can open up a new range of possible uses in various […]

  • Discovery of a new protein gives insight into a long-standing plant immunity mystery
    on December 6, 2019 at 6:24 pm

    When a plant senses an invading pathogen, it activates a molecular signaling cascade that switch on its defense mechanisms. One such mechanism involves sacrificing host cells to the pathogen. This is a tightly controlled process that involves the work of plant proteins to ensure that the sacrificial cells are only killed if the pathogen is attacking. This process, called the cell death response, ensures that only a few host cells die.

  • Scientists have spotted new compounds with herbicidal potential from sea fungus

  • Island 'soundscapes' show potential for evaluating recovery of nesting seabirds
    on December 6, 2019 at 5:53 pm

    Nocturnal seabirds nesting on remote islands can be extremely difficult to study. An increasingly important tool for monitoring these populations involves acoustic sensors deployed in the field to record sounds over long periods of time. But analysis of the resulting recordings to identify and count the calls of different species can be time-consuming, even with computers and artificial intelligence.

  • Using a molecular motor to switch the preference of anion-binding catalysts
    on December 6, 2019 at 5:52 pm

    Many organic molecules are chiral, which means that they are non-superimposable on their mirror image. Those mirror images are called enantiomers and can have different properties when interacting with other chiral entities, for example, biomolecules. Selectively producing the right enantiomer is therefore important in, for example, pharmaceuticals. University of Groningen chemists Ruth Dorel and Ben Feringa have now devised a method that not only achieves this but that also controls which […]

  • Surface effects affect the distribution of hydrogen in metals
    on December 6, 2019 at 5:47 pm

    The researchers from Peter the Great St.Petersburg Polytechnic University (SPbPU) and Institute of Problems of Mechanical Engineering of the Russian Academy of Sciences studied the distribution of hydrogen in metals in the process of standard testing for hydrogen cracking. They found that there is a surface effect that does not let hydrogen enter the metal. This can result in errors in industrial quality control of material, and to fundamental errors in terms of scientific research of hydrogen […]

  • Reduced soil tilling helps both soils and yields
    on December 6, 2019 at 5:00 pm

    Agriculture degrades over 24 million acres of fertile soil every year, raising concerns about meeting the rising global demand for food. But a simple farming practice born from the 1930's Dust Bowl could provide a solution, according to new Stanford research. The study, published Dec. 6 in Environmental Research Letters, shows that Midwest farmers who reduced how much they overturned the soil—known as tilling—increased corn and soybean yields while also nurturing healthier soils and […]
